"I don't think in the last two or three hundred years we've faced such a concatenation
of  problems all at the same time.... If we are to solve the issues that are ahead of us,

we are going to need to think in completely different ways."

Why Solar?

".... you're not going to be self-sufficient, or even produce half of our energy from biomass in the U.S., if we want to eat.... The difficulty is that plants do not collect very much solar energy. On average, plants collect one-tenth of one percent of the solar energy available. Photovoltaic solar cells collect at least 10 percent, which means 100 times the energy collected by plants. Biofuel Skeptic Extraordinaire.... When these people talk about biofuels providing us with our energy, they need to look at the facts right now. Eighteen percent of all corn is going into ethanol production. We're getting 4.5 million gallons of ethanol. That's 1 percent of U.S. petroleum use. It's 1 percent. If we use 100 percent of U.S. corn, and we won't do that, but if we used 100 percent, what would that do for us? Six percent."

Biofuel Skeptic Extraordinaire
Grist, 8 December 2006

"Humanity’s 'primary energy production,' including all fossil fuels, nuclear power, hydroelectric and renewables, is 13 terawatts (equivalent to 13,000 large power plants), less than 1/100 of 1 percent of the 170,000 terawatts continuously delivered to the earth as sunlight. With 600 terawatts of terrestrial potential, solar energy far exceeds all other possible forms of substitution..... A direct path from sunlight to electricity can be 10 times as efficient as photosynthesis. Solar energy can’t be touched or put into a bottle. Solar is radiant energy, not a solid, liquid or gas. Electricity from renewables is ideally suited for urban transportation. It is nonpolluting and well-suited for fixed guide rail and automated routing of traffic, and an electric vehicle is at least twice as efficient as a gasoline vehicle. We are ready for a good reason to get rid of the internal combustion engine in dense urban areas, where it is about as practical as a campfire in the kitchen. Efficiency in the face of oil depletion is that compelling reason. Solar technologies continue to improve, and so do electric vehicles. A battery with three times the energy density of lead-acid and a charging time under two minutes is scheduled for introduction in 2007 or 2008."
Dawn of the Solar Era - A Wake-Up Call
Solar Today, March/April 2006


"Bloomberg reported last week that a number of solar developers in Spain have applied for permits to connect to the country’s electric grid and sell solar power at market prices. Taken together the permit requests total 37,5 gigawatts (GW = 1,000 megawatts). ... The rest of the world has Spain to thank for inching so far out into traffic that they lost the hood ornament on the car: the stimulus effect from that program (and that of Germany – which has spent a couple billion Euros for 30,000 MW of solar – and other European countries) helped create a global industry with rapidly falling costs and increasing efficiencies. As a consequence, we are now able to talk seriously about grid parity of solar resources, and sun-drenched Spain has gotten to the point that utility-scale programs can be envisioned without subsidies."

".... this year, Friedman’s team succeeded so spectacularly in bending the rules of the solar spectrum that NREL and its industry partner, Solar Junction, won a coveted R&D 100 award from R&D Magazine for a world-record multijunction solar cell. The three-layered cell, SJ3, converted 43.5% of the energy in sunlight into electrical energy — a rate that has stimulated demand for the cell to be used in concentrator photovoltaic (CPV) arrays for utility-scale energy production. Last month, that record of 43.5% efficiency at 415 suns was eclipsed with a 44% efficiency at 947 suns. Both records were verified by NREL. This is NREL’s third R&D 100 award for advances in ultra-high-efficiency multijunction cells. CPV technology gains efficiency by using low-cost lenses to multiply the sun’s intensity, which scientists refer to as numbers of suns."

"By harvesting waste heat, researchers from the US Department of Energy’s National Renewable Energy Laboratory (NREL) have for the first time built a solar cell with an external quantum efficiency over 100 percent. A cell's external quantum efficiency is the number of electrons flowing per second in its external circuit, divided by the number of photons per second entering it, and is different at different wavelengths. "
Solar cell could be cheaper than fossil fuel
TG Daily, 19 December 2011


" companies are increasingly optimistic that, with technological advances and improvements in manufacturing efficiency, it won't be too long before 'grid parity' — the point at which solar power is equal to or cheaper than conventional energy sources — is reached, especially if oil prices remain high.... If the technology continues to improve, solar power could achieve parity within five to 10 years, says Peter Thiele, executive vice president of Sharp's energy-solutions division in Europe. Or even sooner, if panel prices continue to fall while oil prices rise. Observers say sales growth is rebounding as buyers respond to increasingly cost-effective solar power."
Solar Power: Sunshine's Cloudy Days

Those who believe that future wars will be fought over global energy supplies and other natural resources include John Reid (former UK Defence Minister), Paddy Ashdown (former High Representative for Bosnia and Herzegovina), Bill Clinton (former US President), Joe Lieberman (Senator and former Vice Presidential running mate to Al Gore), and Mike McConnell (US Director of National Intelligence to George W Bush).

Improved global energy conservation will need to play a vital role in trying to pre-empt the occurrence of these harrowing scenarios. But large amounts of energy will still be required as the world population expands and develops.

Finding new sources of energy in this context is an essential part of establishing and maintaining world peace and stability. Reserves of traditional fossil fuels are depleting, and their are even doubts about the adequacy of global uranium supplies to fuel nuclear reactors. By contrast there are other sources of energy which cannot be depleted as long as the sun continues to shine.

Most forms of renewable energy are driven partly or wholly by the sun - wind, wave, hydroelectric, near surface ground source heat, biomass, and even tidal (through gravitational effects, although the influence of the moon is much greater), are all part of the framework of solar energy in one form or another.

All of these have a potentially important role to play in moving humanity towards the onset of a new solar based society. This web page, however, focuses on news items related to the development and use of direct solar thermal and solar photovoltaic energy systems.

"Solar installations offer a cheaper alternative to biomass over the lifetime of a system according to a new report from the Natural Resources Defense Council (NRDC), which also claims that biomass produces higher carbon emissions than coal and natural gas. The new study from the US-based environmental advocacy group has examined the full system costs of renewables like wind and solar relative to biomass under carrying assumptions about the total economic costs of each. The analysis took into account the latest technology costs, the cost of ensuring reliability of supply, and carbon costs and concluded that in 2020, biomass will be more costly than wind and solar alternatives. This is due in part to the continually falling costs of these renewable technologies which are expected to continue into the next decade. Meanwhile, biomass conversion is already a mature technology and so the potential for technology costs to fall is limited. This means that comparatively little capital cost reduction is expected over time while fuel costs, which make up the bulk of biomass costs, are highly uncertain whereas solar installations do not carry this lifetime cost. Sasha Stashwick, a senior advocate with NRDC, said: “The economics of biomass don’t make sense as the UK strives to replace coal and decarbonize its power sector. This report clearly indicates that when you account for total economic costs, cleaner alternatives like wind and solar are the lower cost solution for a coal-free UK. It’s just good economic sense.”"

"UK-based Camborne Energy Storage has installed a grid scale solar power storage facility in Somerset using US-based Tesla’s revolutionary battery technology. The first of its kind in Europe, the installation, which comprises of five 100 kWh Tesla powerpacks, will store energy produced from a nearby solar farm in Somerset. Providing an ancillary service to the National Grid, the installation has the capacity to provide power for over 500 homes.  This new project will not only demonstrate the capabilities of Tesla’s technology in the renewable energy sector but, more importantly, showcase how the UK can viably reduce its reliance on fossil fuels and nuclear power."

"Ever since Tesla announced its merger with Solar City, we’ve been waiting for the first crossover product. According to CEO Elon Musk, we won’t be waiting long. Tesla is planning to unveil a “solar roof” with an integrated battery system and Tesla charger on October 28th, marking the first time that Tesla will move into the electricity generation game. The integrated solar roof and battery was the first item in Elon Musk’s Master Plan Part Deux released back in July. At the time, Musk described it as “a smoothly integrated and beautiful solar-roof-with-battery product that just works, empowering the individual as their own utility, and then scale that throughout the world. One ordering experience, one installation, one service contact, one phone app.”"

"The world's next energy revolution is probably no more than five or ten years away. Cutting-edge research into cheap and clean forms of electricity storage is moving so fast that we may never again need to build 20th Century power plants in this country, let alone a nuclear white elephant such as Hinkley Point. The US Energy Department is funding 75 projects developing electricity storage, mobilizing teams of scientists at Harvard, MIT, Stanford, and the elite Lawrence Livermore and Oak Ridge labs in a bid for what it calls the 'Holy Grail' of energy policy. You can track what they are doing at the Advanced Research Projects Agency-Energy (ARPA-E). There are plans for hydrogen bromide, or zinc-air batteries, or storage in molten glass, or next-generation flywheels, many claiming "drastic improvements" that can slash storage costs by 80pc to 90pc and reach the magical figure of $100 per kilowatt hour in relatively short order. “Storage is a huge deal,” says Ernest Moniz, the US Energy Secretary and himself a nuclear physicist. He is now confident that the US grid and power system will be completely "decarbonised" by the middle of the century. The technology is poised to overcome the curse of 'intermittency' that has long bedevilled wind and solar. Surges of excess power will be stored for use later at times when the sun sets, and consumption peaks in the early evening. This transforms the calculus of energy policy. The question for the British government as it designs a strategy fit for the 21st Century - and wrestles with an exorbitant commitment to Hinkley Point - is no longer whether this form of back-up power will ever be commercially viable, but whether the inflection point arrives in the early-2020s or in the late 2020s. One front-runner - a Washington favourite - is an organic flow battery at Harvard that uses quinones from cheap and abundant sources such as rhubarb or oil waste. It is much cheaper and less toxic than current flow batteries based on the rare metal vanadium. Its reactions are 1,000 times faster."

"What if your entire roof was made up entirely of dedicated solar power cells? No, not adorned with the current kind of solar panels you’ve likely seen on the existing roofs of a few neighbour houses – an entire roof actually made up of solar gathering material, rather than add-ons that install after the fact. That’s the vision described by Elon Musk in SolarCity’s investor call yesterday (via Elecktrek). Musk, who acts as board Chairman rather than occupying a company executive role, joined TeslaCity likely because of his proposal that Tesla buy SolarCity. That deal remains in progress, with a $2.6 billion stock offer agreed upon by both companies and now awaiting shareholder approval. On the call, Musk followed a reveal by SolarCity CEO Lyndon Rive that SolarCity would have two product s to unveil by the end of this year with a comment that the company is working on “a solar roof, as opposed to modules on a roof.” Rive echoed the product details, and Musk said that part of their product’s appeal vs. Other solutions will be that customers end up with “a beautiful roof,” as opposed to “a thing on the roof.” By creating a product that actually replaces roofing material, SolarCity’s power generation offering becomes not an add-on, but a core housing component, with a much easier sell opportunity both for new construction and whenever a home has to re-roof (typically once every 20 years or so depending on the type of shingle used). Both Musk and Rive signalled they see a huge market opportunity in new roof builds."

"The energy-storage market will go “ballistic” in the final two months of this year, Tesla Motors CEO Elon Musk said Wednesday, when the company ramps up production of batteries he promises will be “head and shoulders above anything else I’ve even heard announced as future plans from other companies.” Exactly one year ago Musk called the energy-storage market “staggeringly gigantic,” and although Tesla utility-scale Powerpacks and residential-scale Powerwalls have since rolled out, Musk cautioned then and continued to caution Wednesday that the real launch comes at the end of 2016 and the beginning of 2017. “It’s going to be heavily concentrated in Q4 and probably heavily in November and December, but I think it’s going to be real exciting when people see it,” Musk said Wednesday afternoon during the Tesla Motors Q2 earnings call. “That’s why I expect kind of exponential growth from there. It’s really going to go ballistic.” Tesla battery competitor AES Corp. also sees a promising market, but in characteristically more conservative language, AES CEO Andres Gluski predicts the market will be “quite large” in five years. Musk believes the market is large now, and Tesla’s only constraints are on the production side.."

"Solar power is on pace for the first time this year to contribute more new electricity to the grid than will any other form of energy – a feat driven more by economics than green mandates. The cost of electricity from large-scale solar installations now is comparable to and sometimes cheaper than natural gas-fired power, even without incentives aimed at promoting environmentally friendly power, according to industry players and outside cost studies. Buoyed by appeals to self reliance and environmental stewardship, as well as government subsidies, the early solar industry was dominated by rooftop panels that powered individual homes and businesses. But such small-scale installations are expensive, requiring hefty incentives to make them attractive to homeowners. Today, large systems that sell directly to utilities dominate. They are expected to account for more than 70 percent of new solar added to the grid this year, according to industry research firm GTM Research. The success of large-scale solar has raised questions about the wisdom of continuing incentives for rooftop installations, which remain far more expensive than most other forms of electricity. Unsubsidized utility-scale solar power costs $50 to $70 per megawatt-hour (or 5 to 7 cents a kilowatt hour), compared with $52 to $78 for the most efficient type of gas plant, according to a 2015 study by investment bank Lazard. Generating power from residential rooftop panels is far more expensive, ranging from $184 to $300 a MWh before subsidies, the report said."

"UK solar has continued to break domestic records after generation reached a new peak of delivering almost a quarter of electricity demand.The data was released by the Solar Trade Association (STA) alongside MyGridGB as part of its third ‘Solar Independence Day’ being held today (Monday 4 July) and claims that 23.9% of demand was met by solar energy early last month. According to Sheffield Solar, which records PV generation across the UK in an effort to help the transmission network operator National Grid keep track of intermittent energy sources, solar generated 61.7GWh on Monday 6 June. This was the second highest day of solar generation in the UK after 4 May, when 62.6GWh was achieved. Installed solar capacity in the UK is thought to have reached almost 12GW after Solar Intel revealed last month that 1.553GW was installed in Q1 2016. Much of this has come through utility-scale solar farms, which were being rushed to completion by 31 March when the latest degression occured in the government's Renewables Obligation support scheme."

"Solar power has gone beyond a revolution on our rooftops. It's forging ahead to a position where it will become the dominant form of new power generation full stop. Thanks to rapid cost reductions that have surprised even the experts, large-scale solar is on the verge of transforming Australia's energy mix, whatever the outcome of the July 2 election. McKinsey is predicting that in less than 10 years, the only new generation capacity that will get built in Australia will be solar, with one or two exceptions."

Financial Review, 24 June 2016

"South Korean scientists have created solar PV cells that are 1 micrometer thick, hundreds of times thinner than most PV and half again as thin as other kinds of thin-film PV. (The research is in a paper just published in Applied Physics Letters.) The cells are made with gallium arsenide as the semiconductor, "cold welded" directly onto a metal substrate, with no adhesive to make them thicker. Remarkably, they produce roughly as much power as thicker PV cells, though in testing, "the cells could wrap around a radius as small as 1.4 millimeters." With cells this thin, solar PV can be integrated in all sorts of "wearables" — clothes, glasses, hats, or backpacks with solar cells integrated, continuously feeding power to our portable electronics. More to the point, PV could be integrated into just about anything. This isn’t the thinnest solar cell ever, either. Back in February, MIT researchers made solar cells so small and light they could sit atop a soap bubble without popping it. The process takes place in a vacuum chamber at room temperature, without the solvents and high temperatures required to make conventional PV. Researchers say the same fabrication process could work with a number of different materials, including quantum dots or perovskites, yielding solar cells small and transparent enough to be embedded in windows or building materials. Now, all these lab breakthroughs are just that: lab breakthroughs. It’s a long road from the lab to a commercial product. Plenty could go wrong in between. But the trends in solar innovation are clear. Cells are getting smaller and smaller, and more and more flexible, using new fabrication techniques that are less and less resource-intensive. It’s all super expensive now, and probably will be for a while. Eventually, though, these new methods will find their way into markets and start getting scaled up. With scale, costs come down."

"The amount of electricity generated using solar panels stands to expand as much as sixfold by 2030 as the cost of production falls below competing natural gas and coal-fired plants, according to the International Renewable Energy Agency. Solar plants using photovoltaic technology could account for 8 percent to 13 percent of global electricity produced in 2030, compared with 1.2 percent at the end of last year, the Abu Dhabi-based industry group said in a report Wednesday. The average cost of electricity from a photovoltaic system is forecast to plunge as much as 59 percent by 2025, making solar the cheapest form of power generation “in an increasing number of cases,” it said."
Solar Power to Grow Sixfold as Sun Becoming Cheapest Resource
Bloomberg, 22 June 2016

"Bloomberg New Energy Finance (BNEF) projects that in most countries, solar PV will be the cheapest form of new electricity generating capacity by 2030. It predicts several major shifts in power markets. The world is about a decade away from reaching the point of "peak fossil fuels" in the electricity-generation sector, after which less will be burned each subsequent year. That's according to BNEF New Energy Outlook (NEO) for 2016, released to subscribers on Monday. NEO is a comprehensive annual look-ahead focused on the development of global clean energy markets and technologies. The turnabout is happening "not because we're running out of coal and gas, but because we're finding cheaper alternatives," writer Tom Randall wrote in a summary of NEO 2016's main findings. There are several major shifts coming to power markets. First, as Randall puts it, "there will be no golden age of gas," despite the huge ramp-up of fracked gas in the US since 2008, which displaced a lot of coal-generated power. Nuclear power won't play a major role either. The reason: Wind and solar power costs are falling too quickly for gas to ever dominate on a global scale. Even with rock-bottom coal and gas prices, a global transition toward renewable energy will occur. NEO 2016 estimates that utility-scale solar PV will drop in price per MWh by 60 percent by 2040, to a global average of about $40 (35 euros) per MWh. "You can't fight the future," said Seb Henbest, NEO 2016's lead author. "The economics are increasingly locked in." The report pegged the peak year for coal, gas and oil in the global electricity generation sector at 2025. Second, renewable energy investment will absorb the majority of financial investment in the power sector through 2040. NEO 2016 projects that up to $2.1 trillion will be spent on new fossil-fueled generating capacity over the next 25 years globally. That's a lot of money. However, wind, solar and hydropower projects will together absorb about $7.8 trillion over the same time-frame. By 2027, building new wind farms and solar fields will often be cheaper than running existing coal and gas generators, according to NEO 2016: "This is a tipping point that results in rapid and widespread renewables development." By 2028, affordable batteries will be ubiquitous, eliminating concerns over the intermittency of wind and solar power. NEO estimates that for every doubling in the global installed capacity of solar PV panels, costs per unit of new panels drops by about 26 percent - a very high "learning rate." Wind power prices are also dropping fast, with a learning rate of 19 percent. This means, according to NEO, that wind and solar PV will be the cheapest ways of generating electricity in most of the world by the early 2030s. Another factor favoring the shift to renewables is that the total numbers of installed wind turbines and solar PV plants are growing faster than total electricity demand. The result is that coal and gas-fired power plants are idle more and more of the time - because they have to pay for fuel, whereas wind turbine or solar PV plant operators don't. Whenever the wind is blowing or the sun is shining, cheap wind or solar electricity displaces fossil electricity. The financial economics: Coal and gas power plants are getting progressively worse as a result. Power companies are aware of this trend, which is why they're increasingly reluctant to invest in new fossil-fueled generating capacity. The foregoing refers to electricity generation, not fuel for transportation. Peak oil demand will take longer to arrive, because most cars will still burn diesel or gasoline for years to come. But electric vehicles (EVs) are on the verge of disrupting oil markets nevertheless - and EV penetration has major implications for electricity markets. NEO 2016 projects that EVs will make up about one in four cars on the road in 2040, adding 8 percent to total global electricity demand by that year." NEO 2016 points to India as a key emerging threat to climate stability, because its electricity demand is expected to increase fourfold by 2040, and "the country sits atop a mountain of coal. It intends to use it," Randall wrote. That's in contrast to China, which is engaged in a massive shift from coal to renewables that will see it reduce its carbon emissions over the next 25 years. India is the main reason that global coal use will remain flat between now and 2040, rather than declining, according to NEO."
Cheapest power in 2030: solar PV
Deutsche Welle, 13 June 2016

"The solar power industry says it has seen the loss of more than half its 35,000 jobs due to recent changes in government energy policy, just at a time when solar power has eclipsed coal as a major generator of Britain’s electricity. Experts believe ministers had cut subsidies too far and too fast, praising the “seismic”, record-breaking growth of solar in recent years. This month the Solar Cloth Company became the latest to be put into administration, following the liquidation and 170 job losses at Solarlec two weeks ago. The biggest single collapse was late last year when the Mark Group went into administration with almost 1,000 redundancies."

"It looks like 2016 may be solar energy’s time in the sun. Not only did the U.S. have more new solar capacity additions — mainly installations of solar photovoltaic panels — in the first quarter than all other energy sources combined, but going solar is becoming more affordable. In the three months ending March 31, there were 1,665 megawatts (MW) of solar power plants — accounting for 64% of total capacity additions — more than coal, natural gas and nuclear combined, according to a joint report by the Solar Energy Industries Association’s (SEIA) and GTM Research, the research arm of Greentech Media, an energy and greentech company.  This growth comes on the heels of a record 2015, in which solar exceeded natural gas capacity additions on an annual basis for the first time ever, the report said."

"Researchers at the Massachusetts Institute of Technology published a paper this week in the journal Nature Energy in which they describe how they built a working solar thermophotovoltaic device (STPV). Using this revolutionary new setup, the researchers think they can dramatically increase the amount of energy solar panels generate by harnessing some of the energy current panels waste. A normal solar cell converts sunlight into energy and delivers it to a storage mechanism. Meanwhile, the heat energy created in the process simply dissipates and is wasted. Scientists have been working for years to find a way to harness some of that wasted heat, and now it appears as though the team at MIT is onto something. The MIT researchers have added a new layer to a solar cell's structure that absorbs heat energy and converts it to light, which is then reflected off to another solar cell. The reflected light is also delivered to the second cell at the perfect wavelength for peak efficiency."
Breakthrough tech could double the amount of energy generated by solar cells
Yahoo Tech, 25 May 2016

"Australian engineers have taken us closer than ever before to the theoretical limits of sunlight-to-electricity conversion, by building photovoltaic cells that can harvest an unheard-of 34.5 percent of the Sun's energy without concentrators - setting a new world record. The previous record of 24 percent was held by a large, 800-square centimetre solar cell produced by a US company, but these new photovoltaic cells aren't only more efficient, they also cover far less surface area, which means they're going to make solar power even cheaper. "This encouraging result shows that there are still advances to come in photovoltaics research to make solar cells even more efficient," said one of the researchers, Mark Keevers, from the University of New South Wales (UNSW) in Sydney. "Extracting more energy from every beam of sunlight is critical to reducing the cost of electricity generated by solar cells as it lowers the investment needed, and delivering payback faster." This UNSW team is the same one that set a new solar conversion record back in 2014, by using mirrors to concentrate sunlight and achieve 40 percent efficiency. But this new record is even more impressive, because it didn't involve any concentration, and it was something engineers hadn't expected to achieve for several decades. "A recent study by Germany’s Agora Energiewende think tank set an aggressive target of 35 percent efficiency by 2050 for a module that uses un-concentrated sunlight, such as the standard ones on family homes," said one of the researchers, Martin Green. "So things are moving faster in solar cell efficiency than many experts expected."  The new cell is only 28 square centimetres (11 square inches) and it works by splitting the incoming sunlight into four bands. The infrared band of that light is reflected back towards a silicon solar cell, and the other three bands are directed into a three-layer, new type of solar cell, made of: indium-gallium-phosphide; indium-gallium-arsenide; and germanium.... To be clear, these four-junction solar cells aren't likely to end up on the rooftop of your home or office anytime soon - they're harder to maintain and more expensive than the standard single-junction solar cells we're used to seeing. But this type of photovoltaic cell is ideal for solar towers, which use mirrors to concentrate sunlight onto a series of cells, and then convert that directly into electricity, often through heat - as is this case in this giant Moroccan solar plant. Or this record-breaking system in Sweden and Australia. The team is now looking to scale-up its solar cells and see what kind of results they can achieve when they're 800-square centimetres in size, like the previous record holders. Right now, the theoretical limit for a four-junction device is thought to be 53 percent, which means even with their tiny cell, the UNSW team is two-thirds of the way there."

"Researchers at Lund University in Sweden have successfully explained how iron-based dyes work on a molecular level in solar cells. The new findings will accelerate the development of inexpensive and environmentally friendly solar cells. The goal is to be able to use iron-based dyes in solar cells in the future. By using iron instead of other more expensive and rare metals, the production of solar cells and light catchers will become cheaper and more environmentally friendly. The demand for solar cells is therefore expected to significantly increase."

"The sun provided British homes and businesses with more power than coal-fired power stations for 24 hours last weekend. While solar power has previously beaten coal for electricity generation over a few hours in the UK, Saturday was the first time this happened for a full day. Analysts said the symbolic milestone showed how dramatic coal’s decline had been due to carbon taxes, as solar had “exploded” across the UK in recent years. National Grid data gathered by climate analysts Carbon Brief showed that 29 gigawatt hours (GWh) of power was generated on Saturday by solar, or 4% of national demand that day, versus 21GWh from coal-fired power stations."

"A federal study has revealed that if Americans installed solar panels on every roof, it would supply 39% of the total power used by the U.S. Researchers from the National Renewable Energy Laboratory (NREL) used light detection and ranging (lidar) data, geographic information systems and photovoltaic (PV) generation modeling to calculate the suitability of rooftops for hosting solar panels in 128 cities nationwide, representing about 23% of U.S. buildings. The total national potential of rooftop solar power is 1,118 gigawatts (billion watts or GW) of installed capacity and 1,432 terawatt-hours (trillion watt hours or TWh) of annual energy generation. That equates to 39% of total national electric-sector sales last year."

"Tesla Motors Inc. said Thursday it has more than 325,000 reservations for its Model 3, the mass-market sedan the electric-car maker unveiled a week ago. That figure implies about $14 billion in future sales, achieved without paid advertising or endorsements, Tesla  said. “Most importantly, we are taking a huge step towards a better future by accelerating the transition to sustainable transportation,” the company said on its website. Tesla claimed the launch was “the biggest one-week launch of any product ever.” Tesla TSLA, -2.77%   unveiled a prototype of the Model 3, scheduled for delivery in late 2017, last Thursday at its design studio in the Los Angeles area. A surge of interest greeted the sedan: Within hours, Tesla’s Chief Executive Elon Musk announced that reservations had surpassed 100,000 online and in stores. Wall Street had expected 100,000 reservations in the first weeks.  Thousands lined up in Tesla stores across the globe to be the first to put down a refundable $1,000 to reserve the Model 3, expected to cost $35,000 before incentives and go 215 miles between charges. Online reservations opened shortly after."

"A US government agency says it has attained the “holy grail” of energy – the next-generation system of battery storage, that has has been hotly pursued by the likes of Bill Gates and Elon Musk. Advanced Research Projects Agency-Energy (Arpa-E) – a branch of the Department of Energy – says it achieved its breakthrough technology in seven years. Ellen Williams, Arpa-E’s director, said: “I think we have reached some holy grails in batteries – just in the sense of demonstrating that we can create a totally new approach to battery technology, make it work, make it commercially viable, and get it out there to let it do its thing,” If that’s the case, Arpa-E has come out ahead of Gates and Musk in the multi-billion-dollar race to build the next generation battery for power companies and home storage.... The battery storage systems developed with Arpa-E’s support are on the verge of transforming America’s electrical grid, a transformation that could unfold within the next five to 10 years, Williams said. The most promising developments are in the realm of large-scale energy storage systems, which electricity companies need to put in place to bring more solar and wind power on to the grid. She said projects funded by Arpa-E had the potential to transform utility-scale storage, and expand the use of micro-grids by the military and for disaster relief. Projects were also developing faster and more efficient super conductors, and relying on new materials beyond current lithium-ion batteries. The companies incubated at Arpa-E have developed new designs for batteries, and new chemistries, which are rapidly bringing down the costs of energy storage, she said."

"Researchers at the Massachusetts Institute of Technology (MIT) have developed the thinnest and lightest solar cells ever made, which could eventually be used to power the next generation of personal electronics. The process of creating the small, flexible cells – measured at a thickness of only 1.3 micrometers and a surface density of 3.6 grams per square meter – was described by MIT professor and associate innovation dean Vladimir Bulovic along with researcher Annie Wang and doctoral student Joel Jean in the April edition of Organic Electronics. The scientists developed the organic cells by growing a parylene-C polymer substrate film in a vacuum, creating solar units that are comparable in their energy output to those utilizing a traditional glass design. By growing the cell, substrate, and coating together in a lab in one process, development was streamlined and the cells end up being less exposed than if the components were created separately.  “The innovative step is the realization that you can grow the substrate at the same time as you grow the device,” Prof. Bulovic said in a MIT news release. The process can also be completed at room temperature without the addition of solvents and chemicals not used in the final product, unlike more demanding solar-cell production methods commonly employed today. Instead, the cell components are grown in a vacuum at room temperature simply through the vapor deposition of polymer precursors that eventually react and settle to form the cell’s parts together....the cells created so far are functional and efficient; they have a weight-based power of more than 6 watts per gram, about 400 times higher than the output of glass solar cells, despite being about 1/1000th the thickness of those units.... In order to collect the creations, the team used glass to carry the final cell systems, but the relatively simple process allows for the possibility of placing the cells on a variety of materials, including fabric, rubber, and more. “It could be so light that you don't even know it's there, on your shirt or on your notebook,” Mr. Bulovic said in a news release. “These cells could simply be an add-on to existing structures.”"

"The U.S. solar industry installed 7,286 megawatts of solar power in 2015, according to data from GTM Research and the Solar Energy Industries Association (SEIA). The figures, announced Monday, represent an increase of over 1,000 megawatts of solar photovoltaic installations compared to 2014. Photovoltaic technology is able to directly convert sunlight into electrical energy. According to the data, solar beat natural gas capacity additions for the first time ever, with 29.5 percent of all new electric generating capacity met by solar power in 2015."

"China, the world’s largest consumer of energy, surpassed Germany as the country with the most installed solar capacity after record additions last year. The nation added 15.1 gigawatts of new solar last year, bringing the total to 43.2 gigawatts, the National Energy Administration said Friday on its website. That’s equal to more than a quarter of global additions and a third of the nation’s solar-panel production, the NEA said. China’s solar capacity has surged almost 13-fold since 2011, according to data from Bloomberg New Energy Finance. Germany had 38.4 gigawatts of power supply from the sun at the end of 2015, while the U.S. had 27.8 gigawatts, according to BNEF."

"Last week, France’s minister of Ecology and Energy announced that the country will pave 621 miles of road with solar panels over the next five years, with the goal of providing cheap, renewable energy to five million people. Called "the Wattway," the roads will be built in collaboration with the French road-building company Colas and the National Institute of Solar Energy. The company spent the last five years developing solar panels that are only about a quarter of an inch thick and are hardy enough to stand up to heavy highway traffic without breaking or making the roads more slippery, David Rogers reports for Global Construction Review. The panels are also designed so that they can be installed directly on top of existing roadways, making them relatively cheap and easy to install without having to tear up any infrastructure."There is no need to rebuild infrastructure," Colas CEO Hervé Le Bouc told Myriam Chauvot for the French magazine Les Echoes in 2015. "At Chambéry and Grenoble, was tested successfully on Wattway a cycle of 1 million vehicles, or 20 years of normal traffic a road, and the surface does not move." The panels are made out of a thin polycrystalline silicon film and coated in a layer of resin to strengthen them and make them less slippery. Because the panels are so thin, they can adapt to small changes in the surface of pavement due to temperature shifts and are sealed tightly against the weather, Fiona MacDonald reports for ScienceAlert. According to Colas, the panels are even snowplow-proof, although plows need to be a little more cautious so as not to rip the panels off the ground."

"While recent advances in solar technology have made the process of harvesting the sun’s energy less costly and more widespread than ever, Massachusetts Institute of Technology (MIT) researchers have developed a new way to farm and store solar heat, according to a university news release. MIT professor Jeffrey Grossman, postdoctoral researcher David Zhitomirsky, and graduate student Eugene Cho say they have created a new type of polymer film that can soak up energy from the sun during the day and store it for a later release of heat. This material could prove beneficial in a variety of circumstances, as heat from the sun is available only for, on average, less than half of the day worldwide. A new solar-based heating polymer could be an advantage in places with less sunlight or frequent cold. Technology that converts the sun’s rays into heat or electricity is not a new development, but the material developed by the trio of researchers uses a new chemical process. While previous attempts at storing heat from the sun using similar solar thermal fuels were successful, they were only usable as liquid solutions and therefore not practical for many everyday needs. A solid polymer, however, could be more easily integrated into commonplace products or industrial processes.... The polymer could be woven into clothing to charge in daylight and instantly warm a wearer during the nighttime or cold hours. The material is also comparable in thickness to bonding polymers currently used in car windows, and could be installed in a similar way to quickly melt snow and ice from window glass. The MIT team will continue work on the film as they try to improve its capacity and color, but its release in the future could signal a big step for heating operations."
Will a new solar-powered polymer help keep us warm?

"One of the limitations of current solar panel technology is the panels need to be facing in a certain direction to make the most of the Sun's rays, otherwise the amount of energy they can absorb drops off dramatically. A newly invented material could make the direction of solar panels much less of a concern in the future. The material has been produced by electrical engineers at the King Abdullah University of Science & Technology (KAUST) in Saudi Arabia and Taiwan's National Central University. Not only does the glass coating they've come up with soak up sunlight from multiple angles more effectively, it's also able to keep itself clean - the newly treated panels were able to maintain 98.8 percent of their efficiency after six weeks outdoors. For several years now experts have debated whether solar panels are more productive when facing south or west, with the majority concluding that it really depends on where in the world you live. If the new coating can be produced on a mass scale, not only will panels become more efficient, they can also be placed in all kinds of positions to catch the sunlight. To create the glass coating, the researchers integrated ultrathin nanorods and larger honeycomb-shaped nanowalls into the existing material: the ability of the nanorods to capture subwavelengths of light and the scattering ability of the nanowalls combine to lead to a boost in efficiency of between 5.2 and 27.7 percent. In the long term, as much as a 46 percent efficiency improvement could be possible, depending on the angle of the light."

"Researchers in the US have figured out how to make solar cells absorb significantly more sunlight than they previously could by making the tiny wires that lie across the top of solar cells effectively invisible. Conventional solar cells are panels with a square grid of wires interlaced over the top of them. These wires are necessary to conduct the electrical charge absorbed by the cell, but while they might not look like they’re really blocking the cell’s capacity to absorb sunlight, in reality they are – obstructing 5–10 percent of the light that would otherwise hit the cell. If only you could make those wires… disappear? Well, it seems that we can.“Using nanotechnology, we have developed a novel way to make the upper metal contact nearly invisible to incoming light,” said one of the researchers, Vijay Narasimhan from Stanford University. “Our new technique could significantly improve the efficiency and thereby lower the cost of solar cells.” ...With expectations that their nano-wire sheeting could boost the efficiency of conventional solar cells from 20 to 22 percent, the researchers plan to test the design on a working cell to see how it performs in the real world."

"SolarCity today said it has manufactured the world's most efficient rooftop solar panel. The photovoltaic panels have an efficiency exceeding 22%, the company said, 7 percentage points higher than the average rooftop panel efficiency rating of roughly 15%. "The new SolarCity panel generates more power per square foot and harvests more energy over a year than any other rooftop panel in production and will be the highest volume solar panel manufactured in the Western Hemisphere," the company stated in its news release. SolarCity is headed by Tesla Motors CEO Elon Musk. It was founded by Musk and his cousins Peter Rive and Lyndon Rive.  SolarCity said it will begin production of the new solar panels in small quantifies this month at its 100 MW (megawatt) pilot facility in Freemont, Calif. The company, however, eventually plans to begin mass production of the panels in its 1 GW (gigawatt) facility in Buffalo, N.Y.  The 1 GW facility is expected to produce from 9,000 to 10,000 solar panels per day once it's running at full capacity, SolarCity stated.  According to SolarCity, the new panels were measured as having a 22.04% module-level efficiency by Renewable Energy Test Center, a third-party certification provider. The new panels produce 30% to 40% more power over the current models, but they cost the same to manufacture -- about .55 cents per watt, according to Bass. The panels, which are 1.61 meters or 1.81 meters in size, depending on the model, will have a capacity of 355 watts each."

"Advances in solar power are happening so quickly that they could herald the end of the era of large coal-fired or nuclear power stations in Britain, according to senior executives at National Grid. “From a consumer’s point of view, the solar on the rooftop is going to be the baseload,” Steve Holliday, the transmission network’s chief executive, said. “Centralised power stations will be increasingly used to provide peak demand.”"
Grid shouts it from the rooftops: the future belongs to solar power
London Times, 28 September 2015

"National Grid finance chief Andrew Bonfield says solar panel costs are falling so rapidly that energy from the sun is expected to be one of the most cost-effective ways to power homes within 18 months. With home storage of electricity and using battery technology fast advancing in the United States, he said that the prospect of pulling the plug on a power company and going off-grid could become a reality for all in the UK within five years. “From a consumer’s point of view, the solar on the rooftop is going to be the baseload,” Steve Holliday, the transmission network’s chief executive, said. “Centralised power stations will be increasingly used to provide peak demand.” Mr Holliday, who is scheduled to leave National Grid next year after 15 years with the business, said that energy markets were “clearly moving towards much more distributed production and towards microgrids” — a big break from the past, when big power stations delivered centralised power to consumers and businesses on demand....Mr Holliday made his remarks in an interview with World Energy Focus, a publication of the World Energy Council, an alliance of 90 nations that collaborate on energy policy matters. “The amount of solar being added to the system is incredible,” he said. “[There was] 1,500 megawatts in the first three months of this year. That’s the capacity of two power stations. I made a comment to the energy minister four years ago that there was little probability we would have 20,000MW of solar in the UK. Now three of our scenarios have more than 20,000MW of solar by 2035.”"

"When world leaders assemble in Paris next month for the United Nations Climate Conference, they will have to consider a difficult issue: Where humans will get enough energy to meet their needs without destroying the planet. From a purely scientific perspective, solar is the only solution. Humanity's most ambitious goals -- such as pulling another 2 billion people out of extreme poverty, or getting a grip on global warming -- require an abundant source of clean, renewable energy. The question is how to choose among options such as solar, wind and biomass. To that end, a group of scientists from Germany's Max Planck Institute for Biogeochemistry decided to figure out which energy source has the most potential to satisfy humans' long-term needs. Their result is striking: Solar can offer about 100 times as much clean energy as any other source. The total solar energy hitting the Earth at the top of the atmosphere is about 175,000 terawatts, or about 10,000 times what humans currently use. Much of this gets absorbed in the atmosphere, where it fuels winds and storms and helps drive ocean flows. A bit less than half reaches the planet's surface in the form of radiation energy. Humans collect the sun's energy in two ways. First, we employ solar technology to harvest the light radiation directly. Second, we get it indirectly, by burning organic matter (oil or coal) that the sun helped to grow, or by harnessing the wind and waves that the sun's light stirs up. Each method has its own physical limit -- the amount of sunlight that, according to the laws of thermodynamics, it can convert into usable energy. The scientists from Max Planck find that the indirect method is by far the most wasteful. For wind energy, the best possible efficiency -- defined as the fraction of initial sunlight captured for human use -- is only about 0.5 percent. Making biofuels from plants operating through photosynthesis turns out to be only slightly better, with a maximum efficiency of 1.5 percent on land, mostly because plants manage to gather light energy only from a small fraction of the spectrum. The direct approach is much better. The scientists estimate that energy can be harvested with 93 percent efficiency from direct sunlight, and 73 percent from diffuse, ambient light. The combination of abundance and efficiency makes solar power far more promising than other energy sources. Using satellite data on global radiation patterns, the scientists estimate the maximum solar energy derivable over land at 16,300 terawatts, about 1,000 times our current energy usage. That's more than 100 times what can be had from either wind or biomass. Adding energy gathered over the oceans doesn’t change the picture much. To be sure, photovoltaic technology remains far from ideal. The current average efficiency is only 20 percent, well below the theoretical maximum. Still, even with such devices, the available solar energy exceeds our current use by more than 250 times. Hence, it makes sense to keep expanding the use of solar technology, which has been growing at nearly 5 percent a year for 20 years. We can meet our energy needs with solar farms covering only a small fraction of the planet, particularly if one assumes that efficiency will improve."

"More American homes than ever before are getting solar panels. The market to install solar panels on the roofs of homes in the U.S. set another record in the second quarter of this year, indicating a shift in the U.S. solar panel industry towards home owners and consumers. According to a new report from research firm GTM Research and the Solar Energy Industry Association trade group, the recent record beat out the amount of solar panels installed on home roofs in the first quarter of this year, which itself was a record at the time..... The amount of home solar roofs grew 70% year-over-year for the most recent quarter, and went from four states with vibrant residential solar markets in 2013, to ten states today.... Overall the growth in both the utility-scale and residential solar markets in the U.S. this year has been impressive. There are now over 20 gigawatts of solar panels operating in the U.S., which can power 4.6 million U.S. homes. So far this year, 40% of all the new electricity-generating capacity came from solar."
Solar panels just broke another record in the U.S.

"Manhattan has approximately 47,000 buildings with around 10.7 million windows, according to a 2013 estimate from The New York Times. Now imagine if just 1% -- or 100,700 -- of those windows could generate electricity through transparent photovoltaics. That's the idea behind solar power windows, and at least two companies are hoping to sell the technology to window manufacturers, saying once installed in a building the technology will pay for itself in about a year. "If you look at the glass that's manufactured worldwide today, 2% of it is used for solar panels; 80% of it is used in buildings. That's the opportunity," said Suvi Sharma, CEO of solar panel maker Solaria. Solaria uses existing photovoltaic (PV) cells and slices them into 2.5mm strips. It then sandwiches those thin PV strips between glass layers in a window. "The way human eye works, you don't even notice them," Sharma said. An additional benefit? As the PV strips absorb light striking a building's window, they reduce the "solar heat gain coefficient"; in other words, the windows reduce the sunlight's effect on a building's internal air temperature and thereby lower air conditioning costs. Solaria is targeting its technology for windows that will be installed in newly constructed buildings. Another company, SolarWindow Technologies, is pitching a different form of transparent PV cell technology for new construction, replacement windows and retrofits to existing windows. SolarWindow is using what it calls organic photovoltaics, which can vary in color and transparency. The company is planning to announce its product in a couple of weeks. SolarWindow CEO John Conklin said what sets his company's technology apart is its ease of integration. Because it's based on a PV film, it can be adhered to existing windows or incorporated into manufactured products relatively easily. Depending on the number of south-facing windows, which receive a majority of the sun's light, and the building's location in the U.S., Solaria's technology could provide from 20% to 30% of a skyscraper's energy needs, Conklin said. Conklin would not disclose exactly which organic material SolarWindow uses. In 2013, however, Oxford University researchers released the results of a study on how neutral-colored, semi-transparent solar cells made of perovskite could be used in building and car windows to generate electricity. Perovskite is an oxide used in ceramic superconductors. The Oxford researchers said they could create transparent solar cells with comparatively high efficiencies. For example, the researchers were able to drive PV efficiencies up to 20% in a "remarkably short period of time" using a simple cell architecture. The university's work is being commercialized by Oxford Photovoltaics (a spin-out company), which is planning to produce attractively colored and semi-transparent glass, which works as a solar cell and could be integrated into the facades of buildings and windows. Similarly, a team of researchers at Michigan State University (MSU) has developed a new type of transparent solar concentrator that when placed over a window creates solar energy. Called a transparent luminescent solar concentrator (TLSC), MSU's technology can not only be used on building windows but also on cell phones and any other device that has a clear, uncolored surface. Richard Lunt of MSU's College of Engineering said the key to the TLSC technology is that it's completely transparent. "No one wants to sit behind colored glass," Lunt, an assistant professor of chemical engineering and materials science, said in a statement. "It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent." MSU's solar harvesting technology uses small organic molecules developed by Lunt and his team to absorb specific nonvisible wavelengths of sunlight. One problem with MSU's technology is that more work is needed to improve its energy efficiency. Currently it is able to produce a solar conversion efficiency close to 1%, but the researchers hope to achieve efficiencies beyond 5% when fully optimized. Today, traditional solar power panels that reside in solar farms or on building rooftops can achieve a PV efficiency of about 15% to 20%. The efficiency rating refers to how much of the photons striking a solar cell are converted into energy. Solaria's solar window technology can achieve a solar effiency of about 8% to 10%. SolarWindow's Conklin would not disclose his company's technology efficiency rating, but did say it was less than standard PV panels. "Obviously when you're looking at absorbing visible light and it's transparent, it's not as efficient as an opaque panel," Conklin said. When it comes to solar windows, however, efficiency matters less than transparency, Conklin said. "When you're looking at transparent or clear photovoltaics, it's not necessarily a function of power conversion efficiency as it is about using the vast amount of space available for that tech," Conklin said. "We're making use of the space that right now is not available for solar energy production. Passive windows are turned into active energy generating windows." In other words, transparent solar PV is about not wasting perfectly good real estate in order to supplement a building's power requirements. The solar window technologies utilize varying methods of transmitting the energy that the PVs produce to a building's internal power infrastructure. Solaria, for example, hides its wiring in the window's frame, and the connectors are wired into a newly constructed building's electrical conduits. Those conduits lead to a central power inverter, which converts the solar windows direct current to alternating current that's usable in the electric grid. SolarWindow's technology can come with micro DC-to-AC power inverters, allowing the electricity to be used only in one room with a solar window. Alternately, it can be connected to a distributed microgrid inverter to power a single floor of a building or to a central inverter from which the entire building can draw power. Solaria is already piloting its windows in "a few" buildings and it is working on the first large-scale commercial projects in California and Europe, according to Sharma. Sharma did not disclose the projects..... Solar windows will cost about 40% more than conventional windows, but the ROI is achievable in under a year and there's big demand even though products have yet to ship, the manufacturers say. "It's actually very viable and will be even more viable as we approach our product launch," Conklin said. "It's in very high demand because right now skyscrapers... don't have a good way of offsetting energy through renewable energy generation." "

"Thousands of householders are installing solar-powered "smart meters" that promise to cut household bills by £250 a year. The development comes as state payouts for renewable energy produced in homes fall sharply. The devices track when rooftop solar panels produce excess energy and divert it to a water heater. The hot water can be used later, saving on gas and electricity bills. Any gadget that claims to improve the return on solar panels will come as welcome news to home owners who could see subsidies cut by 87pc as part of a government reform to the "feed-in tariff". If you bought solar panels today the Government would pay a feed-in-tariff rate of 13p per kilowatt hour (kWh). But from January this rate will drop to less than 2p.  The move will cut the taxpayer-funded subsidy by £192 per year for a typical household as ministers attempt to halt a £1.5bn overspend on renewable energy."

"A team of experts from the University of Exeter mimicked the v-shaped posture adopted by the butterflies to heat up their flight muscles before take-off. In doing this, they were able to increase harvested solar power in panels by almost 50%. The power-to-weight ratio of the overall solar energy structure was also increased 17-fold in the process, making it much more efficient. Professor Tapas Mallick, lead author of the research said: "Biomimicry in engineering is not new. However, this truly multidisciplinary research shows pathways to develop low cost solar power that have not been done before." Being the early birds among butterflies on cloudy days, the Cabbage White butterflies that take off early have limited access to solar energy. The V-shaped posturing used on such days helps them maximise the amount of solar energy onto their thorax and fly. Sub-structures on their wings reflect light efficiently, ensuring that the flight muscles are warmed to an optimal temperature as quickly as possible. The optimal angle of 17 degrees between the wings increases temperature by around 7 degree C as compared when held flat. The Exeter team set out to replicate the wing structure and develop a new, lightweight reflective material for solar panels. Besides the angle, a single layer of scale cells as found in the butterfly wings helped improve power-to-weight ratios of solar concentrators, making them significantly lighter and more efficient. The research by the team from the Environment and Sustainability Institute (ESI) and the Centre for Ecology and Conservation, based at the University of Exeter's Penryn Campus in Cornwall, is published in the leading scientific journal, Scientific Reports. Solar energy is predicted to become the cheapest source of electricity across much of the globe in the next 10 years. It is fast approaching grid parity with fossil fuel power, and in some cases falling even lower as wafers go thinner and more efficient. Solar photovoltaic prices have fallen by 80% since 2008. The global installed capacity of solar electricity has increased by six times to 135GW in 2013 from 23GW in 2010."

"Oman’s largest oil producer ordered work to begin on what will be one of the biggest solar plants in the world, establishing the technology as an alternative to fossil fuels for coaxing crude out of the ground. GlassPoint Solar Solar Inc. will build the facility at the Amal oilfield in southern Oman, according to a statement on Wednesday. Rows of parabolic mirrors covering 2 square kilometers (0.8 square mile) will heat 1,021 megawatts of steam, which will be injected into underground reservoirs to reduce the viscosity of the crude produced there. The development is a landmark both for its scale and because it shows the oil industry can tap renewables instead of its own supplies to power its own facilities. Those energy needs are vast and growing as the top grades of crude drain away, leaving producers dependent on heavier deposits."
World’s Biggest Solar Heat Plant Backed by Oman to Boost Oil

"A consortium of eleven European partners in eight countries claims to have an effcient alternative to silicon that achieves 25% efficiency with its Sharc25 (super-high efficiency CIGS thin-film solar cells) program to produce single-junction thin-film solar cells that rival silicon at 25 percent efficiency for a fraction of the cost of the cheap low-efficiency Chinese varieties. Today run-of-the-mill single-crystal silicon solar cells—the most used variety—average about 25 percent efficiency, although advanced designs have been reported to have efficiencies approaching the theoretical limit of 33 percent. The cheap thin-film variety favored by Chinese manufacturers and other low-cost solar cell suppliers use achieve significantly lower efficiencies, although last month Japan's National Institute of Advanced Industrial Science and Technology (AIST), the Photovoltaic Power Generation Technology Research Association (PVTEC), Sharp, Panasonic, and Mitsubishi reported a triple-junction thin-film solar cell built in a joint venture that achieved in excess of 13 percent efficiency.  The Sharc25 project, coordinated by the Centre for Solar Energy and Hydrogen Research Baden-Wurttemberg (ZSW, Stuttgart, Germany) was funded to the tune of $6.9 million by the European Union's Horizon 2020 program in conjunction with the Swiss government's Federal Laboratories for Materials Science and Technology at Eidgenossische Materialprufungs und Forschungsanstalt (Empa, Dubendorf, Switzerland). "Our solar cells could be used for small devices such as wearables," Ayodhya Tiwari, head of Empa’s Thin Film and Photovoltaics laboratory and the scientific coordinator of Sharc25 told EE Times. "But our main interest is large scale power generation for applications in buildings and solar farms on a utility scale."

"A new power converter chip that can harvest more than 80 per cent of the energy trickling into it has been designed by MIT researchers. Previous ultra-power converters had efficiencies of only 40 or 50 per cent, and where its predecessors could use a solar cell to charge a battery or directly power a device, the new chip can do both, the researchers said. It can power the device directly from the battery. The chip could forge the way for extremely low-power sensors that can run for months without battery changes or that can extract energy from the environment to recharge, which is necessary in the Internet of Things age. Vehicles, appliances and equipment would have their own embedded sensors to feed back information directly to network services, streamlining the maintenance process and coordination of tasks. The chip's operations share a single inductor, its main electrical component, which saves space on a circuit board, but increases the circuit complexity even further while keeping the power consumption low."

"The Government and local councils have splashed millions of pounds of taxpayers’ cash on building thousands of electric car charging points that barely anyone uses. Ministers confirmed that public money had been used to construct a network of of 57,567 publicly-funded charging points as of the end of the last financial year. The figure is roughly double the number electric cars actually registered for use on the road in Britain – around 24,500 as of December 2014, according to the Office for Low Emission Vehicles. Despite the rarity of electric cars, there are now more than six times as many charging points in Britain as there are petrol stations. In 2013 the Government unveiled a £37m grant package to build the charging stations, with cash strapped local councils forking out even more money to install the points. The grant was part of a £400m commitment towards encouraging the take-up of similar cars."

"A new technology developed by scientists at - (UCLA) can store solar energy for up to several weeks -- an advance that could change the way scientists think about designing solar cells. The materials in most of today's residential rooftop solar panels can store energy from the sun for only a few microseconds at a time. The new design is inspired by the way that plants generate energy through photosynthesis. 'In photosynthesis, plants that are exposed to sunlight use carefully organised nanoscale structures within their cells to rapidly separate charges -- pulling electrons away from the positively charged molecule that is left behind, and keeping positive and negative charges separated,' said senior study author Sarah Tolbert. 'That separation is the key to making the process so efficient,' Tolbert said. To capture energy from sunlight, conventional rooftop solar cells use silicon, a fairly expensive material. On the other hand, plastic solar cells - which are cheaper - are relatively inefficient, because the separated positive and negative electric charges often recombine before they can become electrical energy. 'Modern plastic solar cells don't have well-defined structures like plants do. But this new system pulls charges apart and keeps them separated for days, or even weeks,' Tolbert said. 'Once you make the right structure, you can vastly improve the retention of energy,' she added. The two components that make the UCLA-developed system work are a polymer donor and a nano-scale fullerene acceptor. In the new system, the materials self-assemble just by being placed in close proximity. The new design is also more environment-friendly than current technology, because the materials can assemble in water instead of more toxic organic solutions that are widely used today, the researchers said. The findings were published in the journal Science."

"While China has long been a leader in making solar panels, it’s now become the largest market, by far, for solar panels. China has emerged as the world’s largest market for solar panels and in 2015 is expected to be home to a quarter of the planet’s new energy capacity from solar panels, according to a new report from GTM Research. China is rapidly adding as much power generation as possible, and solar is just one source of new energy generation in the country. China is expected to install 14 gigawatts of solar panels in 2015 out of a total 55 gigawatts worth of solar panels installed worldwide. In addition to China, countries in the Asia Pacific region are supposed to count for more than half of the world’s new solar panel capacity this year, including many new solar installations in Japan (a huge market following the reduction of nuclear in the wake of the Fukushima crisis), and an emerging potentially huge market in India. One gigawatt is around the size of a large natural gas or nuclear plant. Usually when people think about solar panels they picture panels installed on the rooftops of homes or buildings. And while that market is growing in some countries, the vast majority of solar panels being installed in China are mounted on the ground, organized into big solar farms, installed in remote areas and sold to utilities. China’s National Energy Administration says that out of the 28.05 gigawatts of solar panels that were connected to the country’s grid by the end of 2014, 23.38 gigawatts came from the ground-mounted type of solar panels."
China is utterly and totally dominating solar panels

"They have become a commonplace sight across Britain: rows of darkly-winking panels nestling across rooftops, quietly generating free energy for the inhabitants below during daylight hours. It is fair to say that the success of solar power has astonished energy analysts over the last five years. The International Energy Agency yesterday forecast that renewables will produce more power than coal within 15 years.Technically, if solar’s current rate of growth continues, its output could match world power demand in just 18 years time. From big banks such as UBS and Citigroup, to environmental groups and technology entrepreneurs, everyone is talking of a 'solar revolution'. The sun has become mainstream, and the world is moving inexorably towards a future that is not only clean, but which promises to democratise energy generation. UK solar output nearly doubled last year and in Britain there is now around 8GW installed across houses, offices, schools and poor-quality land – enough to power 2.4 million homes. Combined with unprecedented cost reductions (a 70 per cent price drop in five years) and massive public popularity (80 per cent plus in repeated opinion surveys), solar power has been an astonishing UK energy success story. Unfortunately, politicians don’t seem to have woken up to the extraordinary implications. Policy changes made towards the end of the last government favour more expensive and less popular technologies, which risks stalling further growth. Other nations, by contrast, are not restraining themselves. Both India and China will have 100GW installed within the next seven years. However, in its official projections, the Department for Energy and Climate Change anticipates that Britain will install only 4GW between now and 2020 - as much as we installed over the past year alone. To follow this pathway would be to constrain a cutting-edge British industry that has the potential not only to generate cost-effective electricity at home, but also to become a leading player in the global market, guaranteeing jobs and revenue. So what do we need to do to develop our solar industry? The first thing is to unlock the barriers to installing solar panels across large rooftops: factories, supermarkets, university buildings, warehouses and the like. Our independently verified analysis shows that the UK can install twice as much solar capacity by 2020 as currently forecast, for only a little more than we estimate current policies will cost. This is a question of using financial support more efficiently and providing better stability for the industry. Our plan would see solar power providing seven per cent of UK electricity in 2020 and providing 57,000 jobs across the solar industry and its supply chains."

"The Spanish government is planning to tax homes that produce their own energy through solar power and store some of it using batteries. A draft decree prepared by the Industry, Energy and Tourism Ministry establishes a new fee to discourage the use of batteries or other storage systems by people who produce electricity, with solar or photovoltaic panels for instance, and who are connected to the national power grid. Under the new rules, these self-reliant consumers will not be able to use products such as the Powerwall battery recently launched by American automotive and energy-storage company Tesla, and will additionally be penalized for the storage systems that come included with the latest generation of solar panels. Only off-grid consumers who have their own, completely independent energy-production systems will be able to use batteries without being penalized for it. Modern storage devices typically have an autonomy of two hours or so, making it difficult to be entirely self-reliant. The new fee will not affect systems without storage, which work only for instantaneous consumption."

"A record amount of solar power was added to the world’s grids in 2014, pushing total cumulative capacity to 100 times the level it was in 2000. Around 40GW of solar power was installed last year, meaning there is now a total of 178GW to meet world electricity demand, prompting renewable energy associations to claim that a tipping point has been reached that will allow rapid acceleration of the technology. 'For the first time ever in Europe, renewables produced more power than nuclear – and solar power was key in achieving this remarkable achievement,' said Michael Schmela, executive adviser to trade body SolarPower Europe, which compiled the statistics published on Tuesday. Britain led the European solar expansion, with government incentives helping to add 2.4GW of solar resources to the domestic market, and a third to Europe’s overall 7GW of growth. Unofficial sources estimated the British numbers even higher – at up to 3GW – based on an analysis of solar module shipments.... Although global growth was impressive, the European pace of development last year slowed to its lowest since 2009, as incentives known as feed-in tariffs were removed across Europe in 2014. Even Germany, the continent’s largest solar market, saw a slight decline in annual installed capacity to 1.9GW, as incentives were cut and market uncertainties increased."

"So what to make of the statement by Saudi Arabia’s oil minister that the world’s biggest oil exporter could stop using fossil fuels as soon as 2040 and become a 'global power' in solar and wind energy? Ali Al-Naimi’s statement is striking as Saudi Arabia’s wealth and influence is entirely founded on its huge oil wealth and the nation has been one of the strongest voices against climate change action at UN summits. 'In Saudi Arabia, we recognise that eventually, one of these days, we’re not going to need fossil fuels,' said Naimi at a business and climate conference in Paris on Thursday. 'I don’t know when - 2040, 2050 or thereafter. So we have embarked on a program to develop solar energy,' he said in comments reported by the Guardian, Bloomberg and the Financial Times. 'Hopefully, one of these days, instead of exporting fossil fuels, we will be exporting gigawatts of electric power.' Naimi also said he did not think that continuing low crude oil prices would make solar power uneconomic: 'I believe solar will be even more economic than fossil fuels.'"

"Engineers in the Netherlands say a novel solar road surface that generates electricity and can be driven over has proved more successful than expected. Last year they built a 70-metre test track along a bike path near the Dutch town of Krommenie on the outskirts of Amsterdam. In the first six months since it was installed, the panels beneath the road have generated over 3,000kwh. This is enough to provide a single-person household with electricity for a year. 'If we translate this to an annual yield, we expect more than the 70kwh per square metre per year,' says Sten de Wit, spokesman for SolaRoad, which has been developed by a public-private partnership..... The project took cheap mass-produced solar panels and sandwiched them between layers of glass, silicon rubber and concrete. 'This version can have a fire brigade truck of 12 tonnes without any damage,' said Arian de Bondt, a director at Ooms Civiel, one of consortium of companies working together on the pilot project. 'We were working on panels for big buses and large vehicles in the long run.' The solar panels are connected to smart metres, which optimise their output and feed the electricity to street lighting or into the grid. 'If one panel is broken or in shadow or dirt, it will only switch off that PV panel,' said Jan-Hendrik Kremer, Renewable Energy Systems consultant at technology company Imtech."

"The Conservative election victory has dealt a severe blow to Britain’s green energy industry, campaigners have warned, as the new majority government prepares to scrap crucial subsidies for renewable power; champion the development of polluting shale gas; and make significant cuts to spending. The renewable industry is most worried about the future of onshore wind farm developments, which the Tories have repeatedly dismissed as an unwanted eyesore despite being cheaper than other forms of green energy. The party’s manifesto pledges 'to halt the spread of onshore wind farms' – and although it is not clear exactly when subsidies for new land-based turbines will be scrapped, an announcement is expected soon. But the Government’s axe is likely to fall across much of the renewable energy industry, campaigners say. They point to David Cameron’s plan to remove what he in 2013 reportedly called the 'green crap' that subsidises renewable power from Britain’s energy bills as evidence of his dislike for alternative energy sources."

"Britain’s antiquated electricity grid is stopping renewable energy projects connecting to the system, threatening the country’s prospects for a low-carbon future, the solar power industry’s trade body has warned. Parts of the grid are closed to new connections and further shutdowns are likely, the Solar Trade Association (STA) said. It claimed the new Conservative government needs to invest heavily in the UK’s power infrastructure to prevent the withering of low-carbon projects and ensure Britain meets its 2020 renewable energy goals. The lack of capacity is at the 14 private sector distribution network operators (DNOs) which carry electricity from the main grid to commercial and domestic users. Western Power Distribution, the DNO for the Midlands, south-west England and Wales, has closed the grid to new large renewable projects in Cornwall, Devon, Somerset and Dorset for up to six years. Large parts of eastern and south-east England barely have any capacity, maps from UK Power Networks, the DNO for these regions, show."

"In recent years, the fast-growing popularity of solar panels has intensified a central challenge: how to use the sun’s energy when it isn’t shining. Now, Tesla Motors, the maker of luxury electric sedans, says it is taking a big step toward meeting that challenge with a fleet of battery systems aimed at homeowners, businesses and utilities. The company’s foray into the solar storage market will include rechargeable lithium-ion battery packs that can mount to a home garage wall as well as battery blocks large enough to smooth out fluctuations in the grid. 'We’ve obviously been working on building a world-class battery, a superefficient and affordable way to store energy,' said Khobi Brooklyn, a Tesla spokeswoman. 'It’s just that we’ve been putting that battery in cars most of the time.' To herald its ambitions in the field, the company scheduled an event Thursday night at its design studio in Hawthorne, Calif., with Elon Musk, its chief executive, presiding. In a news conference before the event, Mr. Musk said the consumer battery, called the Powerwall, would sell for $3,500, and was derived from the batteries that Tesla uses in its Model S vehicles. The device, which Tesla will start producing later this year, will be installed by licensed technicians. The batteries will be connected to the Internet and can be managed by Tesla from afar. Customers can connect up to nine battery packs to store larger amounts of power. 'If you have the Tesla Powerwall, if the utility goes down, you still have power,' Mr. Musk said. He added: 'The whole thing is an integrated system that just works.'.... Tesla’s announcement comes as energy companies are moving in the same direction. Sungevity, a leading solar installer, announced a partnership this week with Sonnenbatterie, a smart energy storage provider in Europe, to begin offering their systems to its customers. NRG, one of the largest independent power producers in the United States, is also developing storage products.... The Tesla systems are designed for different scales. The home battery, roughly four feet by three feet, would allow solar customers to have power in the event of an failure, draw from it when utility rates are higher and use more of the electricity their panels produce, easing reliance on the grid. For utilities, they can help compensate for fluctuations from intermittent sources like solar and wind — whose production can dip sharply or stop altogether — as well as meet demand during peak periods. And for businesses, they can help lower demand for electricity from the grid, which in turn can lower costly demand charges."

"The White House has announced a goal to train 75,000 workers in the solar industry by 2020, many of them veterans. 'These are good-paying jobs that are helping folks enter the middle-class,' President Barack Obama said on Friday at Hill Air Force Base in Utah. The plan will expand on the Department of Energy SunShot Initiative's Solar Instructor Training Network currently running at more than 400 community colleges. The White House also announced the Solar Ready Vets program aimed at helping veterans transition into the solar industry. A joint program between the Department of Defense and the DOE, it's currently being launched at 10 military bases across the country, including Hill Air Force Base and Camp Pendleton in California. Obama touted the new goal as a way to bolster the economy and help meet the White House's climate change goals, which call for greenhouse gas emissions to be cut 26 percent to 28 percent below 2005 levels by 2025. The solar industry is creating jobs at a rate of 10 times faster than the overall economy, the White House said."

"Solar power could provide up to 4% of the UK's electricity by the end of the decade, the government has said. The plummeting cost of solar panels has caused the government to revise upwards its forecast for solar energy use, Energy Secretary Ed Davey said. This had contributed to the government decision to end most subsidies for large-scale solar this month, he added. But the solar industry said the cuts were a mistake and would prevent it from competing with fossil fuels. The price of solar panels has reduced by 70% in the past few years as subsidies in many countries created a mass market and drew in Chinese manufacturers. In the UK this prompted the government to withdraw subsidies from large-scale solar farms - above 5MW - from the end of March. That in turn has created a temporary solar boom as firms race to connect to the grid in the coming days. The Solar Trades Association said as much new capacity has been installed in the first three months of this year as in the whole of 2014. But after April it expects installations to fall 80%, because most firms will not be able to compete."

"Japanese scientists have succeeded in transmitting energy wirelessly, in a key step that could one day make solar power generation in space a possibility, an official said Thursday. Researchers used microwaves to deliver 1.8 kilowatts of power -- enough to run an electric kettle -- through the air with pinpoint accuracy to a receiver 55 metres (170 feet) away. While the distance was not huge, the technology could pave the way for mankind to eventually tap the vast amount of solar energy available in space and use it here on Earth, a spokesman for The Japan Aerospace Exploration Agency (JAXA) said. 'This was the first time anyone has managed to send a high output of nearly two kilowatts of electric power via microwaves to a small target, using a delicate directivity control device,' he said. JAXA has been working on devising Space Solar Power Systems for years, the spokesman said. Solar power generation in space has many advantages over its Earth-based cousin, notably the permanent availability of energy, regardless of weather or time of day. While man-made satellites, such as the International Space Station, have long since been able to use the solar energy that washes over them from the sun, getting that power down to Earth where people can use it has been the thing of science fiction. But the Japanese research offers the possibility that humans will one day be able to farm an inexhaustible source of energy in space. The idea, said the JAXA spokesman, would be for microwave-transmitting solar satellites -- which would have sunlight-gathering panels and antennae -- to be set up about 36,000 kilometres (22,300 miles) from the earth. 'But it could take decades before we see practical application of the technology -- maybe in the 2040s or later,' he said."

"Researchers at Harvard have discovered how to convert solar energy into liquid fuel, potentially accelerating our switch to the alternative-energy source, according to an article in this month’s scientific journal Proceedings of the National Academy of Sciences (PNAS). At the moment, solar energy can be converted into hydrogen by using photovoltaic cells. The hydrogen can then be stored in fuel cells for future use. But hydrogen has failed to make headway as an energy source in a world that is infrastructurally set up to handle liquid fuels. Now, however, scientists have figured out a way of using sunlight to split water into hydrogen and oxygen. They then use a bacterium to convert the hydrogen, plus carbon dioxide, into the liquid fuel isopropanol. 'This is a proof of concept that you can have a way of harvesting solar energy and storing it in the form of a liquid fuel,' said researcher Pamela Silver. The hope now is that solar energy will find more takers, particularly in the developing world, where the ability to make energy locally will be a boon."

"University of Toronto engineers study first single crystal perovskites for new applications Engineers have shone new light on an emerging family of solar-absorbing materials that could clear the way for cheaper and more efficient solar panels and LEDs. The materials, called perovskites, are particularly good at absorbing visible light, but had never been thoroughly studied in their purest form: as perfect single crystals. Using a new technique, researchers grew large, pure perovskite crystals and studied how electrons move through the material as light is converted to electricity. Led by Professor Ted Sargent of The Edward S. Rogers Sr. Department of Electrical & Computer Engineering at the University of Toronto and Professor Osman Bakr of the King Abdullah University of Science and Technology (KAUST), the team used a combination of laser-based techniques to measure selected properties of the perovskite crystals. By tracking down the rapid motion of electrons in the material, they have been able to determine the diffusion length--how far electrons can travel without getting trapped by imperfections in the material--as well as mobility--how fast the electrons can move through the material. Their work was published this week in the journal Science. 'Our work identifies the bar for the ultimate solar energy-harvesting potential of perovskites,' says Riccardo Comin, a post-doctoral fellow with the Sargent Group. 'With these materials it's been a race to try to get record efficiencies, and our results indicate that progress is slated to continue without slowing down.' In recent years, perovskite efficiency has soared to certified efficiencies of just over 20 per cent, beginning to approach the present-day performance of commercial-grade silicon-based solar panels mounted in Spanish deserts and on Californian roofs. 'In their efficiency, perovskites are closely approaching conventional materials that have already been commercialized,' says Valerio Adinolfi, a PhD candidate in the Sargent Group and co-first author on the paper. 'They have the potential to offer further progress on reducing the cost of solar electricity in light of their convenient manufacturability from a liquid chemical precursor.' The study has obvious implications for green energy, but may also enable innovations in lighting."

"Global investment in clean energy jumped 16% in 2014, boosted by fast-growing solar power in the US and China. Solar, whose costs have plummeted in recent years, attracted over half the total funding for the first time. The green energy market has been gloomy in recent years and the rise in investment is the first since 2011. But despite strong growth in most regions, only a series of large offshore wind farms stopped Europe going into reverse, while the Australian government’s antipathy to renewables saw investment there tumble by 35%. The new figures, from Bloomberg New Energy Finance (BNEF), show $310bn (£205bn) was ploughed into green energy last year, just short of the record $317bn in 2011. However, as green energy gets ever cheaper, the money invested in 2014 bought almost double the clean electricity capacity than in 2011."

"California’s Topaz project is the largest solar power plant in the world with a 550 MW capacity, and it is now in full operation. It is located in San Luis Obispo County and has 9 million solar panels. Construction began just two years ago. The electricity produced by the plant will be purchased by Pacific Gas and Electric. The solar panels were manufactured by First Solar and the project was developed by First Solar. SEIA says about 200 homes in California are powered for each MW of solar power capacity. So, for a 550 MW solar plant, about 110,000 homes could be powered when the sun is shining. First Solar has said this figure could be 160,000 homes in the case of Topaz. The San Luis Obispo county population is about 276,000. It might turn out that the majority of this population could be powered by a single solar power plant. Energy storage is a growing field, so it eventually might be that excess electricity generated by solar power could be stored for nighttime use and for overcast days, extending the impact of Topaz even further."

"Barristers, it is said, should never ask witnesses questions unless they already know the answers. Journalists, by contrast, do best by seeking to elicit information that they genuinely do not know. But the other evening I found myself getting a wholly unexpected answer to a question which I had expected would produce a predictable one. The occasion was a scintillating lecture by Prof Sir David King, the former government Chief scientist, put on by Ashden, the charity that runs the eponymous energy awards. That’s not an adjective I apply often to talks, but I was riveted as David ranged over subjects from population growth to water resources, the growth of cities to commodity prices, spewing out new information and insights. But while he said a lot about the promise of renewable energy, he said almost nothing about nuclear power – despite for long having been one of its foremost and most influential advocates in Britain, describing it, for example, as a 'massive economic opportunity' for the country. So I got up and asked him about it, expecting the same pro-nuclear response as I had heard from him many times before. Instead he amazed me by suggesting that Britain 'might well' be able to do without atomic power altogether, and that the real priority should be on developing ways of storing electricity so as to be able to depend on famously intermittent sun and wind. 'We have to keep reassessing the situation', he said. 'I believe that what we need, more than anything, is a surge of activity to develop energy storage capability …. Once we can do that technologically, why would we not just keep with renewables.' For a country like India, with plenty of sunlight and deserts where it can be collected, he went on, 'there’s no reason' for it not to go 'directly wholesale into solar energy'. After all it was already 'three to four times' cheaper to provide villages unconnected to the grid in India and China with solar electric panels and batteries than to connect them up. In countries like Britain and Japan, with less space and sun, he added, 'it was difficult to see that we’re going to reach a position where we don’t want nuclear energy', and in that case he favoured the small 'modular nuclear reactors' recently advocated by the former environment secretary, Owen Paterson. But later he came back to the question and corrected himself: 'if we can get the costs down we might well manage our future basically on renewable energy and energy storage'. Which raised an interesting thought. In recent years there have been several much publicised conversions of former opponents of nuclear power – like columnist and activist George Monbiot, and former Greenpeace executive director Stephen Tindale – to supporting it. Could this be the first example of a powerful nuclear advocate going, at least partially, the other way?"

"Across the world, efforts are underway to improve the way we store and distribute energy, as we move towards more sustainable but intermittent forms of energy generation, such as wind and solar power. Improving the way we store energy is important for the UK’s energy security, as it will allow us to decouple energy generation and its usage. If we can find a better way to store energy it will allow us to save it when it’s generated and use it when it’s required, replacing our current awkward system where generation has to match demand in real time. The UK’s first two-megawatt (MW) lithium-titanate battery is to be connected to the energy grid as part of a new research project to tackle the challenges of industrial-scale energy storage. The project aims to test the technological and economic challenges of using giant batteries to provide support to the grid."
Giant batteries connected to the grid: the future of energy storage?

"A British start-up has developed a way for parking lots and structures with roofs that can’t take much weight to harness the power of the sun. The Cambridge, England-based Solar Cloth Company is beginning to run trials of its solar cloth, which uses lightweight photovoltaic fabric that can be stretched across parking lots or on buildings that can’t hold heavy loads, such as sports stadiums with lightweight, retractable roofs. Perry Carroll, Solar Cloth Company’s founder, told BusinessGreen that the company is working to close deals to install solar cloth on 27,000 parking lots.'We have built a growing sales pipeline worth £4.2m [about $6.57 million] for 2015, including park and ride projects, airport parking operators and retail park owners,' he said. According to Solar Cloth Company, there are about 320 square miles of roof space and 135 square miles of parking space in the U.K. that could be covered by solar cloth, and if all of these spaces were covered, the solar power produced would be enough to power the U.K.’s grid three times. The key to solar cloth’s adaptability is its lightweight nature. An approximately ten square-meter piece of the cloth weighs about 7.3 pounds, far less than a traditional, silicone-based solar panel’s weight of about 35 to 48 pounds. The material is also flexible, which allows it to be installed on most roofs, regardless of their shape."
New 'Solar Cloth' Allows Solar Cells To Be Stretched Across Parking Lots, Stadiums

"On Nov. 12, the very first bike path powered by solar panels will open in Krommenie, which lies just northwest of Amsterdam. Though the lane will stretch only 328 feet in length when it's eventually completed, it's a big step for solar roadways, which, despite much fanfare, are still only in the early stages of development. CityLab notes that the path is a result of a collaboration between the private industry, the government and academia. Solaroad, as it's been dubbed, is made from concrete 'modules' covered with a layer of glass and a friction-inducing layer to prevent accidents. The solar cells are in place beneath only one traveling direction — the other side of the road will be used to test various top layers to see which surfaces work best. "In time, the solar power from the road will be used for practical applications in street lighting, traffic systems, electric cars (which drive on the surface) and households," reads the description. The path does have a few drawbacks. It can't be angled toward the sun, so it receives roughly 30% less solar power than roof panels. It was also incredibly expensive — roughly $3.7 million, paid for largely by the local government. However, once completed, researchers are hopeful that the path will produce enough energy to power three households. Eventually, the plan is to extend the idea to roadways, as the concrete and glass cover are strong enough to support the weight of a truck. The Guardian reported that up to 20% of the Netherlands' road system could be converted to solar roadways, which could help provide energy to things like traffic lights and electric cars. Across the ocean, a pair of Americans, Scott and Julie Brusaw, are attempting to make solar roadways a reality as well. As Mic reported in May, the couple are in the midst of bringing that idea to life. Their Indiegogo campaign has raised more than $2 million so far; they also received a $50,000 private grant and two rounds of Federal Highway Administration funding."
The Netherlands Has Built Something No Other Country Has

"German car manufacturer Mercedes-Benz has debuted a new concept for a hydrogen-powered SUV, and it's pretty crazy. The Vision G-Code is as striking as any concept, with a squat profile and space-age interior, but it's not the car's looks that are interesting here: it's the paint. When the G-Code is stationary, its multi-voltaic' paint generates electricity in a number of ways. It acts like a giant solar cell, turning the sun's energy into electricity, and also charges electrostatically, harnessing the power of the wind.Instead of simply passing the electricity generated onto an internal battery, Mercedes uses it to facilitate hydrogen synthesis, creating fuel for the car's engine. The front wheels are powered by a hydrogen engine, while an electric motor drives the rear axle. It also has some other tricks to aid the production of hydrogen: on the move, further power is drawn from the G-Code's suspension system. One byproduct of the synthesis is oxygen, which Mercedes says "is routed to the interior as needed," providing "a refreshing effect for the occupants." Of course, it's worth remembering this is just a concept, and while its looks may filter down to upcoming models, it's unlikely we'll see the more innovative tech on display in any production cars soon."

"Every time fossil fuels get cheaper, people lose interest in solar deployment. That may be about to change. After years of struggling against cheap natural gas prices and variable subsidies, solar electricity is on track to be as cheap or cheaper than average electricity-bill prices in 47 U.S. states -- in 2016, according to a Deutsche Bank report published this week. That’s assuming the U.S. maintains its 30 percent tax credit on system costs, which is set to expire that same year. Even if the tax credit drops to 10 percent, solar will soon reach price parity with conventional electricity in well over half the nation: 36 states. Gone are the days when solar panels were an exotic plaything of Earth-loving rich people. Solar is becoming mainstream, and prices will continue to drop as the technology improves and financing becomes more affordable, according to the report. The chart below shows how far solar will come out ahead in each state in 2016, assuming a worst-case scenario of lower tax credits. The blue bars show the anticipated cost of solar energy (assuming a conservative 20-year lifespan for the panels) minus average electricity prices. Positive numbers indicate the savings for every kilowatt hour of electricity..... Solar has already reached grid parity in 10 states that are responsible for 90 percent of U.S. solar electricity production. In those states alone, installed capacity growth will increase as much as sixfold over the next three to four years, Deutsche Bank analyst Vishal Shah wrote in the Oct. 26 report. The reason solar-power generation will increasingly dominate: it’s a technology, not a fuel. As such, efficiency increases and prices fall as time goes on. The price of Earth’s limited fossil fuels tends to go the other direction.... The chart below shows the price of energy sources since the late 1940s. The extreme outlier, of course, is solar, which only recently became an expensive blip in the energy marketplace. It will soon undercut even the cheapest fossil fuels in many regions of the planet, including poorer nations where billion-dollar coal plants aren’t always practical. Solar will be the world’s biggest single source of electricity by 2050, according to a recent estimate by the International Energy Agency. Currently, it’s responsible for just a fraction of one percent. Because of solar's small market share today, no matter how quickly capacity expands, it won’t have much immediate impact on the price of other forms of energy. But soon, for the first time, the reverse may also be true: Gas and coal prices will lose their sway over the solar industry."
While You Were Getting Worked Up Over Oil Prices, This Just Happened to Solar
Bloomberg, 29 October 2014

"Solar panels installed on the roof of a home or garage can easily generate enough electricity to power an electric or plug-in gas-electric hybrid vehicle. The panels aren't cheap, and neither are the cars. A Ford Fusion Energi plug-in sedan, for example, is $7,200 more than an equivalent gas-powered Fusion even after a $4,007 federal tax credit. But advocates say the investment pays off over time and is worth it for the thrill of fossil fuel-free driving. 'We think it was one of the best things in the world to do,' says Kevin Tofel, who bought a Chevrolet Volt in 2012 to soak up the excess power from his home solar-energy system. 'We will never go back to an all-gas car.' No one knows exactly how many electric cars are being powered by solar energy, but the number of electric and plug-in hybrid cars in the U.S. is growing. Last year, 97,563 were sold in the U.S., according to Ward's AutoInfoBank, up 83 percent from the year before. Meanwhile, solar installations grew 21 percent in the second quarter of this year, and more than 500,000 homes and businesses now have them, according to the Solar Energy Industries Association. Tofel, 45, a senior writer for the technology website Gigaom, installed 41 solar panels on the roof of his Telford, Pennsylvania, home in 2011. The solar array — the term for a group of panels — cost $51,865, but after state and federal tax credits, the total cost was $29,205. In the first year, Tofel found that the panels provided 13.8 megawatt hours of electricity, but his family was using only 7.59 megawatt hours. So in 2012, Tofel traded in an Acura RDX for a Volt plug-in hybrid that could be charged using some of that excess solar energy. In a typical year, with 15,243 miles of driving, the Volt used 5.074 megawatt hours. Tofel used to spend $250 per month on gas for the Acura; now, he spends just $50, for the times when the Volt isn't near a charging station and he has to fill its backup gas engine. Charging the Volt overnight costs him $1.50, but the family makes that money back during the day when it sends solar power to the electric grid. He estimates that adding the car will cut his break-even point on the solar investment from 11.7 years to six years."
Electric-Car Drivers Trading Gas for Solar Power
Associated Press, 28 October 2014

"[A] study, commissioned by the E.U. and conducted by Ecofys, a renewable energy consultancy, considered the economic costs of climate change, pollution, and resource depletion as well as the current capital and operating costs of the power plants. The authors assessed the cost of generating electricity and any resulting environmental damage. They used a measure known as the 'levelized cost,' the estimated cost per megawatt-hour, without subsidies, of building and operating a given plant in a given region over an assumed lifetime. The authors referred to established models and academic literature to find monetary values for pollution, land use, and resource depletion. And to account for climate change, they assumed a metric ton of emitted carbon dioxide costs around €43 ($55).... Previous studies have looked at the economic impacts of pollution and other environmental consequences of energy production, but the Ecofy analysis is unique in that it includes the depletion of energy resources as an additional cost, says Ann Gardiner, a consultant at Ecofys who co-authored it. Surprisingly, solar power fared poorly in the analysis, costing far more than wind power and nearly the same as nuclear power. The reason, says Gardiner, is that many of world’s solar panels are manufactured in China, where electricity is very carbon-intensive. The depletion of metal resources also represents a larger cost for solar than wind, she says. Gardiner notes, however, that solar technology is still improving and may be more cost-effective today than it was in 2012, the year used for the study. According to the Ecofys analysis, new coal and natural gas plants in the E.U. have levelized costs of just over €50 ($64) (in 2012 euros) per megawatt-hour (assuming they are running at maximum capacity); onshore wind is around €80 ($102) per megawatt-hour; utility scale solar PV is about €100 ($127); nuclear power is around €90 ($115); and hydropower is as cheap as €10.... The environmental costs associated with different forms of energy production are approximations, but they the show the scale of damages associated with each technology. These costs would look different for other parts of the world. Two of the most influential variables are the cost of fuel (natural gas is much cheaper in the U.S., for example) and the capital cost of building power plants, which varies globally by as much as four times, says David Victor, professor of international relations at the University of California, San Diego."

"Investors are seeking funding from the UK government for an ambitious plan to import solar energy generated in North Africa. Under the scheme, up to 2.5 million UK homes could be powered by Tunisian sunshine by 2018. The company involved says they have already spent 10 million euros developing the site. A number of overseas energy producers are competing to bring green energy to the UK from 2017. The TuNur project aims to bring two gigawatts of solar power to the UK from Tunisia if the company wins a contract for difference (CFD) from the British government. Under new rules published by the Department for Energy and Climate Change (Decc) in the Summer, the government will allow developers of renewable energy projects that are not based in the UK to bid for contracts that guarantee subsidies to supply power."

"With a speed of 106.966 kilometres an hour, a solar car known as eVe is now officially the fastest electric vehicle over a distance of 500 kilometres in the world - and it was built entirely by undergraduate engineering students from the University of New South Wales (UNSW) in Australia. The previous record was 73 kilometres an hour, and it stood for 26 years before Sunswift smashed it in July. The Fédération Internationale de l'Automobile, the world motorsport’s governing body, has now updated its official records. 'It's not often you can confidently say you made history before you even graduated,' said Sunswift’s project director and third-year engineering student Hayden Smith in a press release. eVe was built by Sunswift, UNSW’s solar car racing team, and more than 100 undergraduate students were involved in its world record attempt over the past two years. eVe is the fifth solar car to be built by the student-led team, and previous models set a Guinness World Record for the fastest solar car, and a world record for the fastest solar powered road trip from Perth to Sydney."

"China has only completed a quarter of its rooftop solar installation target for this year, industry sources say, raising further concerns about the growth potential of domestic solar panel manufacturers in the world's largest solar market. Early this year, China set a goal of building about 14 gigawatts (GW) of solar generating projects in 2014 - close to Finland's entire power capacity. Of that, it expects 8 GWs to be so-called distributed solar, which includes rooftop panels and other small installations.In the first nine months of the year, however, China has built less than two GWs of distributed solar, industry executives and analysts say. At best, that number may rise to five GWs by year-end, they added."

Why is the Oracle of Omaha, who many consider to be history's greatest investor, willing to invest $30 billion into renewable energy?... Warren Buffett is a man with an enviable problem. His company is simply generating so much free cash flow that it's threatening his ability to grow the company's profits, and thus his investors' (and his own) wealth. Thus, Mr. Buffett has turned to one of the few global industries large enough to grow into: global energy infrastructure and renewable power. These offer not only somewhere to reinvest his rivers of cash, but also tax credits that can help boost Berkshire's earnings growth rate and boost the stock price by a significant amount."

"Researchers have created a 'solar battery' by combining the energy-harvesting panel with the energy-storing medium at a microscopic level. The device could change the way solar power is used, though it still has much to prove. Ohio State's Yiying Wu, professor of chemistry and biochemistry, led the team that made the breakthrough, which was reported this week in Nature Communications. The panel, like any other solar cell, produces electrons when struck by sunlight. But then, instead of having those electrons piped to a separate battery unit and leaking as much as 20 percent of them in the process, they built the battery right into the panel. The solar-sensitive part is porous, and gives access to a battery layer that attaches and detaches oxygen from lithium ions to store energy. 'Basically, it's a breathing battery,' Wu explained in a news release. And, strangely enough, the panel is tuned to a certain wavelength of reddish light by using iron oxide as a dust — also known as rust. Combining the production and storage of solar power could potentially reduce costs and make solar-powered devices compact."

"Wearable electronics are quickly becoming the fashion. And there could soon be a way to power those electronics indefinitely, now that scientists in China have developed a solar cell ‘textile’ that could be woven into clothes. The textile retains a power-generation efficiency close to 1% even after been bent more than 200 times, and can be illuminated from both sides. Scientists have been looking into flexible solar cells for decades, partly for coating irregularly shaped objects but also for integrating into wearable fabrics. One popular line of investigation has been dye-sensitized solar cells, in which a pigment absorbs sunlight to generate electrons and their positive counterparts, holes, before passing on those charges to inexpensive semiconductors. These solar cells are cheap and flexible, but the liquid nature of their pigments means that they must be well sealed. Bend a dye-sensitized solar cell more than a few times and the seals are likely to break, destroying its light-harvesting properties. That is why Huisheng Peng at Fudan University in Shanghai and colleagues have been exploring another option: polymer solar cells. Although their maximum efficiencies fall below 10% – about half that of crystalline silicon, the most prevalent solar cell – polymer solar cells are lightweight, flexible and easy to manufacture. Peng and colleagues’ solar cell textile consists of microscopic interwoven metal wires coated with an active polymer (to absorb the sunlight), titanium dioxide nanotubes (to conduct the electrons) and another active polymer (to conduct the holes). The researches coated each side of the textile with transparent, conductive sheets of carbon nanotubes, which complete the circuit."

"Citigroup said solar already competes in the growing regions of the world on "pure economics" without subsidies. It has reached grid parity with residential electricity prices in Germany, Italy, Spain, Portugal, Australia and the US southwest. Japan will cross this year, Korea in 2018. It forecast that even Britain will achieve grid parity by 2020, a remarkable thought for this wet isle at 51 or 52 degrees latitude. The industry can at last tap a "large investor universe" through the market for asset-backed securities. It priced debt below 5pc last year. Some US electric companies are starting to build solar farms for hard-headed commercial reasons as a hedge against future shifts in the gas price. This is astonishing. Roughly 29pc of all electricity capacity added in America last year came from solar. The story is by now well-known. A McKinsey study found that installed solar power in the US across all sectors has dropped from $6 a watt to $2.59 in four years, largely due to the collapse in the cost of solar cells. The next leap in competitiveness will come from falling "soft costs", currently 64pc of the residential solar price in America. This happened in Germany as scale built up, and is following in the US. In California you can sign up for solar panels in a supermarket, with no money down, and make a saving from day one. The clinching shift will come when the battery storage is cheap enough and lasts long enough for users to draw down their suplus generated during the day to cover needs at night, opening the way for mass exodus from the grid, unless utilities harness it first to their own advantage. There are at least 220 research projects into energy storage currently under way in the US, many funded by the US Advanced Research Projects Agency and other arms of the world's scientific superpower. It is Hegel's irony of history. We can now see that the oil price shock of 2008 was traumatic enough to draw an emergency response, bringing forward oil's nemesis. Harvard is working on an organic flow battery using quinones - from rhubarb - instead of rare earth metals. It hopes to cut battery costs by two-thirds within three years. Rivals at the University of Southern California think they can eventually slash the cost by 90pc below today's lithium-ion batteries. It is a fair bet that scientists will have conquered intermittency by the end of the decade, at which point the switch to renewables becomes a stampede. This is where great fortunes may be made, perhaps the mirror image of the wealth to be lost on fossil defaults. Brokers Sanford Bernstein call it the new order of "global energy deflation". Technology momentum is unstoppable, and one-way only."

"The solar industry is facing a looming shortage of photovoltaic panels, reversing a two-year slump triggered by a global glut. The oversupply pushed prices through the floor, making solar power more competitive and driving up demand. It also dragged dozens of manufacturers into bankruptcy, and slowed capital investment at the survivors. With installations expected to swell as much as 29 percent this year, executives are bracing for the first shortfall since 2006. Scarcity will benefit the biggest manufacturers, including China’s Yingli Green Energy Holdings Co. (YGE) and Trina Solar Ltd. (TSL) A shortage may slow development outside the top markets in Asia and North America if suppliers favor their largest customers. Shipments to large, utility-scale solar farms may get priority over smaller, rooftop systems, threatening one of the industry’s fastest-growing markets. “The cell and module glut has certainly dried up,” said Stefan de Haan, a solar analyst at IHS Inc. “There is no massive overcapacity anymore.” Related: Obama’s Green Dilemma: Punish China, Imperil U.S. Solar. The looming shortage shows the rapid expansion of solar energy. The industry may install as much as 52 gigawatts this year and 61 gigawatts in 2015. That’s up from 40 gigawatts in 2013, and more than seven times what developers demanded five years ago, according to Bloomberg New Energy Finance."

"Battery storage paired with residential rooftop solar arrays are not a thing of the distant future. It’s happening now and companies like SunPower and SolarCity are already selling package systems. SolarCity partnered with Tesla to manufacture a lithium-ion battery storage system. In a pilot program, SolarCity is offering the battery setup to California customers for $1,500 down and $15 a month on a 10-year lease agreement. Currently, the pilot system is only set up to work as a battery backup in case power goes out.... The electric vehicle manufacturer recently announced finalist cities for its proposed Tesla gigafactory, where it will mass produce batteries for energy storage and electric vehicles. In addition to rooftop solar systems paired with storage and electric vehicles that demand batteries, utilities are investing in energy storage technologies.

Solar + Storage Has Arrived:
Clean Energy, 11 July 2014

".... staggering gains in solar power - and soon battery storage as well - threatens to undercut the oil industry with lightning speed, perhaps in a race with cheap nuclear power from a coming generation of molten salt reactors. The US National Renewable Energy Laboratory has already captured 31.1pc of the sun's energy with a solar chip, but records keep being broken. Brokers Sanford Bernstein say we are entering an era of "global energy deflation" where gains in solar technology must relentlessly erode the viability of the fossil nexus, since it goes only in one direction. Deep sea drilling will become pointless. We can leave the Arctic alone. Once the crossover point is reached - and photovoltaic energy already competes with oil, diesel and liquefied natural gas in much of Asia without subsidies - it must surely turn into a stampede. My guess is that the world energy landscape will already look radically different in the early 2020s."

"After decades as an expensive and sometimes impractical source of energy, experts say solar power is finally coming into its own.   Not only has the technology improved the efficiency and cost of solar panels, in some states, rising prices for conventional electricity make solar panels an economical alternative.  But can solar power actually compete with conventional electric utilities?  John Desmarteau waited 10 years before switching to solar, but the retired Washington physician is glad he did.  He says he's cut his reliance on the electric company by 85 percent, and saved the equivalent of more than 200 trees. “In fact, for the last two months, which would be April and May 2014, we’ve used from our electric utility, no electricity," said Desmarteau. The 39 photo-voltaic panels installed on Desmarteau's roof generate three times more than he consumes even with the air conditioning at full blast.  It's not just a greener alternative - for some it can mean real savings.  The industry is still evolving but AstrumSolar's Mark Manthy says companies like his are making it easier for consumers to switch. "In most markets right now, especially up and down the [U.S.] East Coast and the West Coast - you could put solar panels on your house for no money down.  Somebody else owns them, you pay them a monthly payment that is cheaper than you would pay your utility," said Manthy. In many states, brown energy - electricity generated from polluting, non-renewable resources like coal -  is still cheaper than solar.  But green advocacy groups such as the Rocky Mountain Institute say that's changing. “In our most optimistic case that we analyzed, all customers in the Southwest, in the states of California, Arizona, New Mexico, Colorado and Utah would see favorable economics within 10 years and 90 percent of the customers in the Mid-Atlantic," said RMI's Jon Creyts. Some will not wait that long.  American University in Washington just signed a 20-year deal with solar pioneer Duke Energy.  AU’s Chief Financial Officer Doug Kudravetz says the long-term savings are substantial. “We’ve done quite a bit of financial modeling and if brown power goes up five percent a year, we’ll save about $14 million, present value," he said. Barclays Bank believes solar is a big enough threat to the status quo that it downgraded bond ratings for electric utilities. "
Experts: Solar Power Could Soon Pose Economic Threat to Electric Utilities
Voice of America, 7 July 2014

"Last week, for the first time in memory, the wholesale price of electricity in Queensland fell into negative territory – in the middle of the day. For several days the price, normally around $40-$50 a megawatt hour, hovered in and around zero. Prices were deflated throughout the week, largely because of the influence of one of the newest, biggest power stations in the state – rooftop solar. “Negative pricing” moves, as they are known, are not uncommon. But they are only supposed to happen at night, when most of the population is mostly asleep, demand is down, and operators of coal fired generators are reluctant to switch off. So they pay others to pick up their output. That's not supposed to happen at lunchtime. Daytime prices are supposed to reflect higher demand, when people are awake, office building are in use, factories are in production. That's when fossil fuel generators would normally be making most of their money. The influx of rooftop solar has turned this model on its head. There is 1,100MW of it on more than 350,000 buildings in Queensland alone (3,400MW on 1.2m buildings across the country). It is producing electricity just at the time that coal generators used to make hay (while the sun shines). The impact has been so profound, and wholesale prices pushed down so low, that few coal generators in Australia made a profit last year. Hardly any are making a profit this year. State-owned generators like Stanwell are specifically blaming rooftop solar. Tony Abbott, the prime minister, likes to say that Australia is a land of cheap energy and he’s half right. It doesn’t cost much to shovel a tonne of coal into a boiler and generate steam and put that into a turbine to generate electricity. The problem for Australian consumers (and voters) comes in the cost of delivery of those electrons – through the transmission and distribution networks, and from retail costs and taxes. This is the cost which is driving households to take up rooftop solar, in such proportions that the level of rooftop solar is forecast by the government’s own modellers, and by private groups such as Bloomberg New Energy Finance, to rise sixfold over the next decade. Households are tipped to spend up to $30bn on rooftop modules. Last week, the WA Independent market Operator forecast that 75% of detached and semi detached dwellings, and 90% of commercial businesses could have rooftop solar by 2023/24. The impact on Queensland’s markets last week is one of the reasons why utilities, generators and electricity retailers in particular want to slow down the rollout of solar. The gyrations of wholesale power prices are rarely reflected in consumer power bills. But let’s imagine that the wholesale price of electricity fell to zero and stayed there, and that the benefits were passed on to consumers. In effect, that coal-fired energy suddenly became free. Could it then compete with rooftop solar? The answer is no."
Solar has won. Even if coal were free to burn, power stations couldn't compete
Guardian (Comment Is Free), 7 July 2014

"Does it make sense to soak up the sun and use the energy later? The Achilles' heel of self-contained solar systems is batteries. The extra cost doesn't usually pay for itself if your home is already connected to the electricity grid; wired electricity is cheaper than stored. Yet there is a growing number of off-grid homes that make economic as well as environmental sense if the alternative is paying for a new grid connection. Built four years ago, Michael Carpenter's large family home in the Manukau hills was off-grid from the start. Over two kilometres from the nearest supply, grid connection cost was prohibitive. "It was going to be very expensive, with ballpark figures around $100,000." His 4kW of solar panels and 1000Ah battery bank would have cost less than the $60,000 he paid if built now, due to falling panel costs over the past few years. The battery bank can be the costliest component and needs replacement when it wears out. Marijn Weehuizen's Waipu home has just been treated to new batteries after seven years - a $9000 bill. Carpenter believes it's worth it in the long run. "What we would pay in power bills is more than enough to set aside for new batteries," he says. There are a number of battery options, but the most popular is lead acid. While your car battery is 12V and perhaps 60Ah, solar battery banks tend to use 48V DC and store 10-20 times that energy. These are deep cycle batteries, designed to slowly release much of their energy. However if you take too much charge out of them it does shorten their life so they need to be used carefully. Flooded cells need regular electrolyte checks, while costlier sealed units are maintenance-free. Other technologies are coming; "Lithium batteries are starting to come into play and will be quite popular," says Kevin Hunter of Cellpower NZ. "For now they are at quite a high price." Stanton offers NiFe batteries. "They are about twice the price, but virtually indestructible." They also have a long cycle life, he says, and you can replace the electrolyte around five times so they last a lifetime. Both Stanton and Hunter estimate the break-even cost of going completely off-grid is when you face a $20,000 bill for connection. Sue Pugmire, whose Manawatu home has been off-grid since 2000, reckons for their set-up $15,000 is nearer the mark. With a 5kW array and $27,000 spent, she estimates her lead acid and ex-telecom gel cells can hold four days' supply. Her Nissan Leaf electric vehicle holds four days (of average motoring) in its on-board battery if required."
Solar and batteries - an off-grid solution

"Fuel cell technology, which creates power when hydrogen is combined with oxygen, was first used in spacecraft in the 1960s but has since become significantly cheaper and is now seen as an alternative to conventional battery power in cars. Japanese car manufacturer Toyota plans to launch the first fuel-cell car in Europe next year for £40,000."

"A breakthrough in the production of solar cells will make the next generation of solar panels cheaper and safer, and promises to accelerate the development of solar energy over the next decade, scientists said. A technical advance based on an edible salt used in the manufacture of tofu could revolutionise the production of future solar panels to make them less expensive, more flexible and easier to use than the current models seen on millions of roofs across Britain. Researchers believe they have found a way of overcoming one of the most serious limitations of the next generation of solar panels, which are based on toxic cadmium chloride, by simply adding magnesium chloride, an abundant salt found in seawater. A study has shown that the solar cells produced with magnesium chloride – which is also found in bath salts as well as used to coagulate soya milk into tofu – work just as efficiently as conventional cadmium cells but at a fraction of the cost and with much lower toxicity. “We certainly believe it’s going to make a big change to the costs of these devices. The cost of solar is going to match fossil fuels eventually but this is going to get us there quicker,” said Jon Major of the University of Liverpool, who led the research. “Magnesium chloride is incredibly low-cost and it’s simply recovered from seawater. It’s used to de-ice roads in winter and it’s completely harmless and non-toxic. We’ve managed to replace a highly expensive, toxic material with one that’s completely benign and low cost,” Dr Major said. About 90 per cent of the solar panels currently in use are made of photovoltaic cells composed of silicon semiconductors, which convert sunlight directly into electricity. However, silicon is not good at absorbing sunlight which is why the next generation of PV cells will be based on a thin coating of cadmium telluride, which absorbs sunlight so well that it only needs to be about one hundredth of the thickness of silicon. However, although cadmium telluride is seen as the future for solar energy, it is potentially dangerous after it is “activated” with cadmium chloride, a critical step in the manufacturing process that raises the efficiency of converting sunlight to electricity from about two per cent to 15 per cent or more. The Liverpool team attempted to find an alternative to cadmium chloride in the activation step and discovered that it could be done just as well with magnesium chloride, which they sprayed onto a test sample of cadmium telluride with a model aircraft spray gun they bought for £49.99, Dr Major said. In a study published in the journal Nature, the researchers demonstrated that the efficiency of the resulting photovoltaic cells made from cadmium telluride and magnesium chloride were on a par with commercial cadmium telluride cells that had been activated with toxic cadmium chloride. “We have to apply cadmium chloride in a fume cupboard in the lab, but we created solar cells using the new method on a bench with a spray gun bought from a model shop,” Dr Major said. “Cadmium chloride is toxic and expensive, and we no longer need to use it. Replacing it with a naturally occurring substance could save the industry a vast amount of money and reduce the overall cost for generating power from solar,” he said. It is not possible to estimate how much cheaper the new solar cells will be, Dr Major said, but magnesium chloride is about one per cent of the cost of cadmium chloride. In addition, waste disposal will be far easier and cheaper with a product based on a non-toxic salt, he said. Asked why the solar power industry had not thought of using magnesium chloride before, Dr Major said: “We genuinely don’t know. The only reason we can suggest is that cadmium chloride works well so it may be a case of ‘if it’s not broke, why is there a need to fix it?’” Jeremy Leggett, chairman of the renewable energy firm Solarcentury, said that the development is exciting because it promises to make an already competitive industry even more competitive with conventional sources of energy, such as fossil fuels. “Their costs are coming down so fast that they are already knocking the business models of utilities into what some analysts call a ‘death spiral’. Imagine, then, what will happen if developments such as the one described in the new research come to market,” Dr Leggett said."
Breakthrough in solar panel manufacture promises cheap energy within a decade

"Japan is becoming one of the world’s leading solar energy markets. The Ministry of Economy, Trade, and Industry has released a report concerning the country’s growing solar power capacity. Over the past year, Japan’s solar capacity has increased significantly, partly due to the falling cost of photovoltaic technologies and the increased domestic production of these technologies. The government has also been funding the development of the solar energy sector throughout the country quite aggressively. The figures highlighted in the report are based on data provided by the Agency for Natural Resources and Energy. The report shows that more than 7 gigawatts of solar capacity was installed throughout Japan during the past fiscal year. This represents a 10-fold increase over the country’s capacity as recorded in early 2013. Much of Japan’s solar growth is being attributed to the development of commercial solar energy systems and the growing popularity of rooftop photovoltaic systems."

"According to Koh’s estimates, the cost of residential photovoltaic systems declined at a compound annual rate of 10% from 2007 through 2012, as governments around the world provided plenty of incentives for manufacturers to increase output. While pointing out that “solid data are difficult to come by,” the analyst added that “the average cost of automotive batteries was in excess of $1,000/kWh as recently as 2009,” and that according to electric-car and battery manufacturer Tesla Motors Inc. TSLA +0.79% , battery costs had declined to $200-300/kWh earlier this year, “with the company guiding to significant (5% to 10% annually) reductions in the next several years.” “Based on our analysis, the cost of solar plus storage for residential consumers of electricity is already competitive with the price of utility grid power in Hawaii,” Koh wrote. An analysis of California, the second most expensive state for residential electricity, indicates consumers may find solar to be competitive by 2017, with New York and Arizona following a year later, “and many states soon after,” according to the Barclays research team. The trend is clear: Looking out over the next 10 years, residential electric customers in most U.S. states will have a viable alternative to regulated electric utilities, as long as they are able to cough up thousands of dollars to install the photovoltaic panels and batteries. Millions of consumers will be unable to afford the outlay for a solar system, but in California, which saw a terrible spike in electricity rates in 2000 and 2001, many people will be eager to switch to solar, even if the initial investment is high. Solar-panel production is hitting critical mass, pushing prices down. The decline in battery costs may accelerate, as Tesla plans to begin construction of its “gigafactory” for batteries late this year, partnering with Panasonic Corp. PCRFY +1.02% , which will produce fuel cells. Tesla CEO Elon Musk has said the company plans to build many more gigafactories. Musk said this week he will share patents for battery and charger technology with other manufacturers. That means more declines in battery prices."

"Germany is big on renewables and at the beginning of June it succeeded in producing half of its energy from solar power for the first time. But it didn't last long. For just a single day production of solar energy hit 23.1 gigawatts, high enough to provide 50.6 per cent of energy demand. A combinatio of factors such as good weather and a national holiday, when demand tends to be lower, contributed to the country achieving the milestone for the first time. However it signals just what the country's solar infrastructure is capable of according to a renewable energies expert, and will help Germany reach the ambitious goal of producing 80 per cent of its energy from renewables by 2050. The country is currently producing 27 per cent of its energy from renewables on average this year.Germany Trade and Invest’s Tobias Rothacher told The Local he thought this record could be broken every two to three months from now on. Rothacher said that solar power production had increased by 34 percent in the first five months of the year compared to last year as a result of better weather."

"Solar cell efficiencies can be improved by as much as 50% with the use of a new optical element designed by engineers from the University of Utah, according to recent reports. The “optical element” — which is essentially just a thin layer of transparent plastic or glass that can sort and concentrate light — can be readily integrated into the glass covering of a solar panel. As a result, the new “polychromat” appears to represent a fairly cheap means of boosting solar cell performance — though, as always, until the technology is commercialized, there are no certainties.... “Currently, high-efficiency solar cells are very expensive because they have to be carefully manufactured in a complex environment and are only cost-effective for space or defense applications like the Mars Rover,” states Rajesh Menon, a Utah Science Technology and Research (USTAR) assistant professor of electrical and computer engineering at the U. “We have designed a very cheap optical element that can be incorporated into the cover glass of a solar panel that will separate sunlight into various colors.”...There are still challenges remaining, though, specifically with regard to incorporating the technology into production processes — the researchers think that, at the earliest, the technology could hit the solar market in 5-10 years."

"Like many consumers, David Polstein had already done much to reduce energy use in his large Victorian home in Newton, Mass. He replaced his appliances with energy-efficient models, installed better heating and put in new insulation. But he was unable to get a solar system to reduce his utility bill, he said, because his roof is too small and shady to make it worthwhile. Now, that could be changing. Mr. Polstein is considering joining a so-called community solar garden that is under development in his part of the state, one of many similar new arrangements now available in Massachusetts. Through the approach — largely pioneered in Colorado and spreading across the country — customers buy into a solar array constructed elsewhere and receive credit on their electricity bills for the power their panels produce. For developers, such shared or community solar arrays create a new market from the estimated 85 percent of residential customers who can neither own nor lease systems because their roofs are physically unsuitable for solar or because they do not control them — like renters and people living in large apartment buildings. And for those customers, it offers a way into the solar boom, whether they seek to contribute to the spread of clean energy or to reap the potential cost savings."
Buying Into Solar Power, No Roof Access Needed

"Pension fund managers are investing more in solar energy, undeterred by declining returns because the industry is considered a safe alternative to traditional securities such as government bonds. That’s the conclusion of executives from two of the biggest Chinese solar panel manufacturers, which have listed their shares in New York. Trina Solar Ltd. (TSL:US) said it’s seeing more interest from fund managers, and Wuxi Suntech Power Co Ltd. said these managers accept returns as low as 1.7 percent. Pension funds are “prepared to invest more in PV, as they have done with wind, because they see it as a sustainable and reliable income,” Benjamin Hill, president of Trina’s unit in Europe, said in an interview. The comments are evidence that fund managers are getting comfortable with solar projects, tapping stable returns as central banks keep their benchmark lending rates near historic low levels. The European Central Bank earlier this month cut the main refinancing rate to a record 0.15 percent and moved the deposit rate below zero for the first time, meaning banks will be charged to park cash with the central bank.... While the funds are most interested “in big utility-scale projects” earning between 2 percent and 5 percent, they’re content with lower returns if the plant is located in a country with a stable government and regulatory regime, such as Germany and the U.K., Suntech Chief Executive Officer Eric Luo said in a separate interview....While institutional investors generally seek to buy parks starting at 5 megawatts to 10 megawatts, they “also invest indirectly via securitized vehicles of pooled smaller parks,” Seherr-Thoss said by phone from Berlin, where the company is based. He is managing the potential sale of a 30-megawatt plant in France that requires 40 million euros ($54 million) of equity and a portfolio of projects in Japan, he said. Last year, the U.K.’s Lancashire County Pension Fund invested 12 million pounds in a bond for a community-owned solar park and Aviva Plc bought the photovoltaic installations on 4,000 U.K. homes."

"Homeowners and developers installed 1.33 gigawatts of solar panels in the first quarter, the second-largest total on record, according to the Solar Energy Industries Association. Installation increased 79 percent from the same quarter a year earlier with utility-scale projects making up almost two-thirds of the total and homeowner demand surging, the Washington-based trade group said today in a statement. Total installations may reach 6.6 gigawatts this year, driven by residential rooftop systems and more than 12 gigawatts of utility projects under development, said Shayle Kann, vice president of research at Boston-based GTM Research, which publishes the quarterly market reports with SEIA. This was the first quarter when residential systems exceeded commercial and government solar."

"INSTALLING state-of-the-art solar panels on 250,000 roofs could meet one-sixth of Scotland’s electricity demands, according to researchers. Scientists believe the strategy could help the one in three Scottish households which they claim are currently struggling to provide themselves with adequate heat and hot water. Experts from the University of Edinburgh, along with other researchers, business leaders and public sector representatives, contributed to a new report which sets out how Scotland could benefit from solar power. Those involved in the project say it offers the most comprehensive assessment yet of Scotland’s solar energy potential, and argue that harnessing energy from the sun on the roofs of south-facing buildings could have 'significant economic, environmental and social impacts'. Solar power could help Scotland meet renewables targets, create jobs and make sure the energy needs of people in cities and rural areas are met, the project found."

"India’s new government led by Narendra Modi plans to harness solar power to enable every home to run at least one light bulb by 2019, a party official said. 'We look upon solar as having the potential to completely transform the way we look at the energy space,' said Narendra Taneja, convener of the energy division at Modi’s Bharatiya Janata Party, which swept to power on May 16 in the biggest electoral win in three decades. About 400 million people in India lack access to electricity, more than the combined population of the U.S. and Canada. The outgoing government led by Prime Minister Manmohan Singh missed a 2012 target to provide electricity to all households. The five-year goal will require the cooperation of state-level administrations with which the central government shares control over the power industry, Taneja said. If successful, solar panels could allow every home to have enough power to run two bulbs, a solar cooker and a television, he said. Expanding clean-power generation will be the administration’s top energy-related priority, especially solar because it has the potential to create jobs and supply millions of scattered households not connected to the grid, he said."

"Subsidies that have driven the spread of large solar farms across Britain are to be scrapped under plans to stop the panels blighting the countryside. Energy companies that build solar farms currently qualify for generous consumer-funded subsidies through the so-called 'Renewable Obligation' (RO) scheme, and had expected to keep doing so until 2017. But the Department of Energy and Climate Change announced on Tuesday that it planned to shut the RO to new large solar farms two years early, from April next year. The decision follows an admission by ministers that far more projects have been built than expected, leading to an rising subsidy bill for consumers and increasing local opposition.  Greg Barker, the energy minister, pledged last month that solar farms must not become 'the new onshore wind' and said he wanted solar panels installed on factory rooftops instead. Although a separate, new subsidy scheme will be made available to large solar farms, it is expected to be far more difficult for solar farms to gain funding under the new regime. A Whitehall source said: 'Large scale solar shouldn't be in any place or at any cost. The direction of travel is away from farms - especially where communities don't want them.'  Leonie Greene, head of external affairs for the Solar Trade Association, said the industry was 'dismayed' at the proposals. She said that the replacement subsidy scheme - so-called 'contracts for difference' (CfD) - simply 'doesn't work for solar'. The new scheme will have a capped budget and onshore wind and solar farm projects will be forced to compete with each other in reverse auctions to win subsidy contracts. Ms Greene said that, on current costs, solar farms 'can't compete with onshore wind'. The uncertainty in the auction process also made solar farm development too risky for the small businesses who typically build them."

"Agua Caliente, the largest photovoltaic solar power facility in the world, was completed last week in Arizona. The plant comprises more than five million solar panels that span the equivalent of two Central Parks in the desert between Yuma and Phoenix. It generates 290 megawatts of power—enough electricity to fuel 230,000 homes in neighboring California at peak capacity. The Agua Caliente Solar Project represents a significant advance in the technology compared with just four years ago, when the largest solar facility in the U.S. generated only 20 megawatts. 'Solar has completely arrived as a competitive energy resource,' says Peter Davidson, executive director of the Loan Programs Office at the U.S. Department of Energy (DoE)."

"Driven by an energy-hungry population and unstable oil prices, countries in the Gulf and the wider MENA region are investing in various green energy options, with a focus on in solar energy. The Middle East could see more than $50 billion investment in its solar power sector by 2020, according to report by Middle East Solar Industry Association (MESIA). The report found that new renewable projects, providing around 37,000 megawatts (MW) of energy, are to be commissioned by the end of this decade. Solar energy projects are forecast to provide around 12,000MW to 15,000MW of power. Saudi Arabia is the largest solar power market in the region with plans to install 23,900MW of renewable energy by 2020. The Kingdom announced plans to spend around $109 billion on solar, in a bid to shift power generation to renewable sources. The UAE too has been stepping up investment in solar. Last year Abu Dhabi launched Shams 1 – the world’s largest concentrated solar power plant (CSP) in operation. The 100MW plant, located in the western region of Abu Dhabi, generates enough clean energy to power 20,000 homes in the UAE. Dubai too opened the first phase of a 13 MW photovoltaic park last year, which has the capacity to generate 1,000MW of power when completed. Despite being abundantly blessed with sun throughout the year, countries in the MENA region have traditionally shied away from investing in solar, citing reasons of commercial unviability in the long term. But attitudes have drastically changed in last few years. Experts point out that a combination of rising population and declining oil reserves has increased the appeal of renewables."

"At long last, this Earth Day we celebrate the true dawn of the Solar Age. That sunrise is hastened, here and abroad, by the slow demise of the once-touted 'too-cheap-to-meter' Atomic Age of nuclear power. As utilities find nuclear power less and less cost effective, new solar photovoltaic installations in the United States are springing up. New solar installations in 2013 reached a record 4.2 gigawatts, bringing the total to 10. On average, one gigawatt of solar photovoltaics powers 164,000 U.S. homes. That means power for 1.6 million homes.  Worldwide, in 2013, solar power installations grew by 38 gigawatts, from 96 to 134. According to the World Nuclear Industry Status Report 2013, in the preceding year, 45 gigawatts of wind and 32 gigawatts of solar power were installed worldwide, compared with a net addition of just 1.2 gigawatts of nuclear. Hastening this energy revolution is the nuclear industry's Achilles heel: an aging, dangerous reactor fleet that is increasingly uncompetitive and new reactor designs that are too expensive to build. Last year, utilities permanently shuttered five more reactors, lowering the number of operating units in the United States to fewer than 100 for the first time in two decades. Utility owners canceled at least nine planned upgrades of existing reactors, deeming the investments no longer economically justifiable. Additionally, nine planned new nuclear reactors were axed in 2013, an indication of how rapidly things have changed. Just five years ago, utilities applied for licenses to construct at least 27 new reactors. By the close of 2013, only four of those reactor projects were still alive."

"It's official. Off-grid energy is moving from the eco-fringe to mainstream. Last month US investment bank Morgan Stanley announced that the off-grid era had arrived: falling prices for renewable energy equipment and rising prices for energy supplied by power companies are fundamentally altering the business model of the trillion-dollar electricity industry. A key piece of the jigsaw came in another statement last month: Tesla Motors are now committing to a huge increase in battery production, bringing down the cost of energy storage capacity by over 50%. The power grid is like a giant battery and up to £500 per year of our energy bills is paying for the maintenance of that battery. Morgan Stanley calculates that Tesla's batteries will only cost an off-grid household £350 per year, rendering the Utility company business model obsolete. 'Our analysis suggests utility customers may be positioned to eliminate their use of the power grid,' says the Morgan Stanley report, Clean Tech, Utilities and Autos. 'We expect Tesla's batteries to be cost competitive with the grid in many states, and think investors generally do not appreciate the potential size of the market.'"

"Internet access fuelled by solar power could soon be a reality. Researchers at the University of Edinburgh have developed technology that enables solar panels to detect broadband signals, allowing data to be transmitted on the world wide web using daylight. In addition, solar energy can be used to power such a device, as well as detect and carry data.... The two technologies combined could enable self-sufficient wireless communications in remote areas, in developing regions with no web infrastructure, or in emergency situations. Prototypes of the system have reached transmission speed of about 7 Mbps, which is equivalent to maximum speeds in conventional wireless networks. The research builds on the Edinburgh team's pioneering Li-Fi technology, which enables data to be transmitted over the Internet using LED light bulbs. Telecommunications pioneer Professor Harald Haas explains the latest developments in his research at the Tam Dalyell prize lecture at the Edinburgh International Science Festival.

"Oregon State University chemists have discovered how to use the sun as more than just a way to harvest passive energy - they can use it to directly produce the solar energy materials that make energy harvesting possible. This breakthrough by chemical engineers at Oregon State University could soon reduce the cost of solar energy, speed production processes, use environmentally benign materials, and make the sun almost a 'one-stop shop' that produces both the materials for solar devices and the eternal energy to power them. Writing in RSC Advances, they say the  work is based on the use of a 'continuous flow' microreactor to produce nanoparticle inks that make solar cells by printing. Existing approaches based mostly on batch operations are more time-consuming and costly. In this process, simulated sunlight is focused on the solar microreactor to rapidly heat it, while allowing precise control of temperature to aid the quality of the finished product. The light in these experiments was produced artificially, but the process could be done with direct sunlight, and at a fraction of the cost of current approaches."

"Solar energy now costs the same as conventionally generated electricity in three European countries. The latest report from an ongoing "PV (Photovoltaic) Grid Parity Monitor" study by consulting firm Eclareon found that the cost of solar- and fossil fuel-powered electricity has the same per kilowatt hour (kWh) price tag in Germany, Italy and Spain. Germany decommissioned all of its nuclear power plants in 2012 after the Fukushima nuclear disaster in Japan. The country has a ways to go to replace that with energy from renewable resources. While Germany is the world's top PV installer, with a solar PV capacity of 35.8 gW at the end of January, the total represents only 3% of its total energy produced there. Germany has set a goal of producing 35% of electricity from renewable sources by 2020 and 100% by 2050.... Cory Honeyman, a solar power analyst with GTM research, said the dropping costs of solar power has spurred utilities to sign contracts to use renewable energy rather than conventional fuels like gas in power plants. For example, utility Austin Energy recently signed a contract to buy solar energy-produced electricity from SunEdison at a rock bottom price of 5 cents per kilowatt hour of energy. SunEdison will generate the power at two solar energy plants in West Texas. 'SunEdison beat out the natural gas prices by 2 cents per kilowatt,' Honeyman said. 'That's a prime example of what we're seeing in terms of [solar plant] projects bid by developers at really competitive prices.' Power costs from plants fueled by renewable energy and conventional fuels fluctuate state-by-state in the U.S. due to subsidies and other factors. According to a July 2013 report from Lawrence Berkeley National Laboratories in Berkeley, Calif., the price of PV solar power plant installation has seen a 'precipitous decline' year over since 2008. On average, the plant installation price has declined by 9 cents per watt (or 14%) for solar installations. Among projects installed in 2012, the median plant cost $5.30 per watt for systems under 10kW in size, $4.9 per watt for systems ranging from 10-100 kW, and $4.6 per watt for systems greater than 100 kW in size. A separate study by Stanford University revealed that it's possible to fulfill all of America's energy needs through renewable energy sources such as wind, solar and hydroelectric, while creating jobs in the process. The Stanford team of researchers created 50 individual plans for how each U.S. state could transition to 100% renewable energy.... The GPM by Eclareon monitored competitiveness in seven European countries with retail electricity prices for residential consumers (PV systems of 3kW) and commercial segment (PV systems of 30kW). Photovoltaics (solar PV) is already price competitive against retail electricity in the commercial sector of major European markets, according to Ecareaon.... While the cost of renewable energy has gone down, high installation prices in Latin America still prevent PV technology from being competitive against grid electricity there, according to Eclareon's report. At the same time, the majority of Latin American countries have been facing retail electricity price decreases. In contrast, European countries such as Germany, Italy, and Spain have reached grid parity. France is the only exception of the analyzed markets in continental Europe, as high irradiation levels and relatively low installation prices are offset by low electricity rates there, the report stated."

"Basic, safe, sustainable sanitation remains an issue for approximately 2.5 billion people world-wide. These people do not have access to running water or safe sanitation methods such as sewage systems or water processing plants. Now, with sufficient sunlight, a new solar powered toilet can serve up to a family of six while turning their waste into a product that they may want. A University of Colorado at Boulder team has developed a toilet that is not only solar powered but can generate biochar. Biochar was used as a farming aid in the Amazon basin almost 3,000 years ago. The indigenous people took wood and leafy greens and roasted them in smothered fires. These low temperature burns created charcoal as opposed to ash. The people then took the charcoal and buried it in the fields to fertilize crops. With the arrival of the Europeans, this type of farming was soon gone but the layers of biochar remained. In the 20th Century, these deposits of black soil were found and in the 1990s it was discovered by scientists that this black soil was actually made by man. The soil deposits were immense. Some of the deposits were up to six feet deep with a total acreage on the order of 180,000 square miles.... The self-contained solar powered toilet was developed by Karl Linden, a professor of environmental engineering at Colorado University in Bolder. The toilet uses the sun’s energy to sterilize the solid human waste, a need and a want of approximately 40 percent of the Earth’s population. In addition to the sterilization of the waste, this particular toilet turns the waste into biochar. Not only simply a soil additive, the resultant product from the toilet may be used for heating.The toilet utilizes the sunlight to heat up the waste and turn it into biochar. This process is done by using eight parabolic mirrors which focus the light on a small area. This, in turn, heats up a bundle of fiber optic cables which transmits the heat to a reaction chamber. The temperatures in this reaction area may exceed 600 degrees Fahrenheit."

"California set back-to-back solar power records last week, the state grid operator said on Monday. The amount of electricity produced from carbon-free solar facilities connected to the grid reached 4,093 megawatts on Saturday, surpassing the day-earlier record of 3,926 MW, the California Independent System Operator (ISO) said in a statement. With 5,231 MW, California leads the nation in installed solar generation, including thermal and photovoltaic facilities, according to the Solar Energy Industries Association. Power generated from solar has more than doubled from June 2012 when the ISO recorded 2,071 MW of peak production, the ISO said. 'This shows that California is making remarkable progress in not only getting new resources approved and connected to the grid, but making meaningful contributions in keeping the lights on as well,' Steve Berberich, president the California ISO, said in a statement. Electricity was being produced by 78 percent of the state's installed solar capacity Saturday, well above the 20 percent of nameplate electric capacity solar plants typically produce on an annual basis, according to the Electric Power Research Institute. The record solar generation accounted for about 18 percent of the state's 22,700-MW demand on Saturday, the ISO said, with the ability to supply about 3 million homes. 'The milestones illustrate that we are well into a new era when clean, renewable energy is shouldering its share of our electricity needs,' Berberich said. California also has about 5,890 MW of wind generation, second only to Texas which has 11,213 MW in commercial operation. California's wind, solar and geothermal resources make up about 15,000 MW of the state's generation mix. California's wind production record stands at 4,302 MW, set June 23, 2013."

"Now that the world’s largest concentrated solar plant is operational in California’s Mojave Desert, the question is whether it will prove its mettle and whether more of those facilities will crop up. The 392-megawatt Ivanpah solar plant doesn’t just have competition from natural gas and nuclear facilities. It is also up against photovoltaic (PV), or rooftop solar panels, which have fallen in price by 70 percent since 2010. Odds are that concentrated solar power (CSP) technology, which focuses the sun’s rays to produce heat, will have a tough time competing, unless it can reduce costs and perfect the technology. 'CSP has fallen by the wayside of the solar industry after attracting huge amounts of government and investor money in 2010 and 2011,' says Ed Cahill, a research associate with Boston-based Lux Research and lead author of its recent report on CSP. ' But the industry can still bring the technology back to the forefront for utility-scale, stand-alone power applications.' The plunge in solar PV prices has led to 4,400 megawatts of solar-panel installations in the United States. PV’s gain will be CSP’s loss. Because several large plants are in the pipeline, the 520 megawatts of CSP capacity in operation now could become 1,300 megawatts by year end. But after that, while PV takes off, CSP's growth will slow and eke its way to 2,000 megawatts by 2018."
Concentrated solar power: Did it miss its chance?

"The latest Bloomberg prediction is that the solar market will grow 20%-plus in 2014. After consulting with 'some of the world’s most knowledgeable and respected solar analysts' – Deustche Bank, HSBC, Citigroup, Yingli, NPD Solarbuzz, Wacker Chemie, and PricewaterhouseCoopers – Bloomberg suggests there will be around 44.5 GW installed. That is only a little less than the 46 GW suggested by the Deutsche Bank. The big story, from 2013, is the change of leadership amongst the world’s solar powers. After dominating the industry for more than six years, Germany is expected to install a mere 3.3 GW this year. Instead of incentives, the owners of clean energy plants may soon be paying a 4.4 euro cents (6 cents) a kilowatt-hour tax. That could turn potential customers away."
Solar to grow 20% in 2014: analysts
The Australian, 6 March 2014

"Energy harvested from the Sun was the second-biggest source of new electricity generation capacity in 2013, but there are clouds on the horizon as a trade war between the U.S. and China stands to throw a monkey wrench in the works... While big utility scale plants like Ivanpah, which harnesses the heat of the sun with concentrated solar mirrors, got most of the headlines, it was small-scale residential systems that drove much of the demand last year. Residential projects increased by 60% over 2012 as the price of installing solar fell and as customers took advantage of leasing options—offered by companies like Solarcity....Last year China installed at least 12 gigawatts of solar capacity, at least 50% more than any other country had ever built in a single year. But that’s where things get cloudy. The U.S. solar boom has been fueled in part by cheap solar panels from China, which have helped bring down the cost of solar power—now 15% cheaper than it was in 2012. But those same cheap Chinese panels have hurt domestic manufacturers of solar PV, even as they’ve helped installers like Solarcity. Several domestic solar manufacturers—led by SolarWorld, an American arm of a German company—have complained that the Chinese government is unfairly subsidizing national solar PV manufacturers, which allows them to undercut their American competitors. In response, the U.S. government agreed in 2012 to impose tariffs of 24 to 36% on Chinese PV panels. But that made little difference—Chinese companies just outsourced much of their production to Taiwan. This year, however, SolarWorld brought a new suit in response, pushing the U.S. to extend those tariffs to Chinese panels made in Taiwan. Last month, the U.S. International Trade Commission said it would move forward with an investigation, and is set to issue a preliminary ruling by the end of March. If those tariffs are indeed extended, you can expect solar power in the U.S. to get more expensive, slowing down growth and hitting installers—who employ far more Americans than U.S. solar manufacturers do—very hard, especially since China has already said it would impose retaliatory tariffs. More expensive panels would likely depress demand for solar in the U.S., hurting installers."

"Volkswagen has released the first official images of the Golf GTE plug-in hybrid ahead of its world premiere at the Geneva motor show on March 4. Claimed to combine the dynamics of the petrol GTI with the cleanliness of electric propulsion, the GTE has a range of about 37 miles in electric-only mode and a total range of 583 miles. Its Combined fuel consumption is 188mpg, with 35g/km of CO2. It will cost about £28,000 after a Government grant has been included. It will be available to order in late August, with the first cars expected in showrooms in late November.Essentially it’s a Golf GTI with a smaller capacity petrol engine and the addition of an electric motor. A 1.4-litre, turbocharged TSI unit develops 148bhp, with a 75 kW/100bhp electric motor integrated into the housing of the six-speed, triple-clutch DSG gearbox to provide a total power of 248bhp. Even better, the combined petrol engine and electric motor develop 258lb ft of torque. Using the electric motor only, the GTE is capable of 80mph. With the addition of the TSI petrol engine, it can accelerate from 0-62mph in 7.6sec, with a top speed of 138mph.  The battery can be fully charged in three and a half hours from a domestic socket, or about two and a half hours using a high-capactiy home charger or public charging site. The car’s socket is located behind the VW badge on the grille.'"

"'You can just imagine the area in New York, Chicago, or Hong Kong: There are huge buildings with big windows. That area is just wasted.' That’s Alan Heeger, a Nobel chemistry laureate, getting enthusiastic about new uses for thin, flexible, semi-transparent solar cells he’s developing using a 'liquid ink' material. The transparent solar cells can generate power for air conditioning and even serve to screen from the sun’s rays. 'It’s like wearing sunglasses,' Heeger explained; the cells act as a solar insulator, reducing the amount of heat radiating in the building. The liquid solar cell material can be printed from a roll-to-roll printing press, much as newspaper is printed; comes in different colors; is durable; and being bendable, can be placed along curved surfaces like the outer walls or windows of high rises. Its lightweight and rugged aspect is very attractive to urban planning specialists because it allows endless possibilities on where and how the solar cells can be applied to surfaces. Another interesting use of these solar cells is on greenhouses. They are light enough to be placed on the roof and sides of the structure, and their transparency lets the sun shine through toward the plants. Heeger suggested that tinting the color of the cells may increase the productivity of the plants below. The possibilities of solar installation are endless with the new variables of flexibility and lightweight technology. This alone may allow people who’ve never considered using solar cells to find ways to apply them to their structures. Solar cells need a reasonably high efficiency to make the cells productive. Heeger explained that he and his colleagues originally sparked the idea in 1995 in the laboratory and created cells that were about one percent efficient. He explained, 'Many people around the world see the potential value in this research. Now, the efficiencies [of our solar cells] are steadily rising up to about 12 percent, and we foresee 15-20 percent in the reasonable future. By utilizing tandem cells, we could probably obtain even higher efficiencies, which is fantastic.'"

"The world's largest solar energy plant has officially opened in California. Sprawling across 3,500 acres in the Mojave desert, Ivanpah solar thermal power plant can produce nearly 400 megawatts of energy - enough to power 140,000 homes. The opening of the $2.2 billion complex of three generating units represents a major milestone in the growing green industry. .... The plant consists of three 459-foot tall towers each with tens of thousands of robotic, heliostats that angle sunlight towards a water boiler. Each heliostat consists of two garage size doors. The reflective area of each heliostat is 163 square feet.  Seen from above the 173,500 heliostats together look like a lake, reflecting the blue sky, but this has proved problematic for birds. Government documents show dozens of dead birds from sparrows to hawks have been found on the site, some with melted feathers. The suspected causes of death include collisions with mirrors and scorching."

"It seems far-fetched to imagine that putting money into solar panels on the roof of your house could deliver a better return than in a private pension. But that is exactly what the energy minister, Greg Barker, argued in an interview with the Telegraph this week. Installation costs for solar panels have fallen, and the Government subsidises the electricity they produce, meaning households could get typical rates of return of between 5pc and 8pc, according to official figures. Average rates on annuities, which many pensioners buy to guarantee a set income for life, are currently around 3.5pc, if the rate of return is linked to inflation. Financial advisers have been swift to warn that while solar panels have their merits, they are no substitute for a pension in retirement planning.  Laith Khalaf, head of corporate research at Hargreaves Lansdown, said: 'There is nothing wrong with the idea of installing solar panels, but it is not a way to save for retirement. Rather, they are something you spend your retirement savings on.' Figures calculated for the Telegraph show that when compared on an annual basis, solar panels could provide a higher income than a pension. But there are certain provisos – and over the long term, the figures appear to swing in favour of pensions. Some 500,000 British homes have installed solar panels, which enable users to generate their own electricity and sell any excess power to energy firms. If a householder spent £7,500 on a 4kWp installation of solar photovoltaic panels to generate electricity, under the current feed-in tariff rates they could generate an income of £770 a year. The Energy Saving Trust, which provided the figures, said that households could earn £555 a year for generating the electricity, as well as £90 a year selling excess power back to the energy companies. The trust estimated that savings on electricity bills would add another £125 a year. These figures are calculated on the current tariff rates, which will fall slightly on April 1, so the average 4kWp system could save around £750 a year. A lump sum of £7,500 paid into a pension by a 50-year-old higher rate taxpayer can produce a tax-free lump sum of £5,600 and a pension income of £504 a year when they retire at 60, according to Hargreaves Lansdown. After income tax at retirement, which is calculated for a basic rate taxpayer at 20pc, this leaves an income of £403 a year. A key advantage of pension saving is that a pension typically comes with an employer contribution, as well as benefiting from tax relief from the Government, so a lump sum can go much further.  For each £100 a saver puts into a pension, for example, a further £100 will typically be added by your employer and the Government. Higher rate taxpayers get a further £25 tax back from the Government, turning a saving of £75 into a pension investment of £200. A pension generates a secure income for life, while the solar panel income will last for 20 years; and the average lifespan of a panel system is 25 years. If the average male, who has a life expectancy of 86, retired at 60, then the £7,500 lump sum would pay out £16,070 in total over his retirement. Women on average live slightly longer, with a life expectancy of 89, so they can expect a total of £17,280. If a pensioner lived until they were 95, which is increasingly common, the initial lump sum would pay out £19,700 over the course of their retirement. These figures are based on assumptions of 6pc investment growth over the decade before the pensioner retires, and an inflation-linked annuity over the course of their lifetime. The expected profit for households for solar panels over 25 years is around £10,500, according to the Energy Saving Trust, based on the income and savings after installation and maintenance costs. ... Mr Khalaf said that rather than replacing a pension in a retirement plan, solar panels could be a good use for the tax-free lump sum people can take out of their pension savings. To extend the tax efficiency even further, people could put the money saved each year on energy bills into an individual savings account (ISA), which will allow the savings to grow each year free of income and capital gains tax.... Once fitted, solar panels require little maintenance and they should last 25 years or more, although the inverter, which converts the electricity for household use, is likely to need replacing at some point, at an approximate cost of between £800 and £1,000.

"Advances in solar technology are set to revolutionise the Building Integrated Photovoltaic (BIPV) market with the development of a new type of cells which combine semi-transparency with good efficiency, opening up the possibility of entire facades formed of electricity generating glass. A paper in the prestigious American Chemical Society (ACS) journal ACS Nano, by Oxford University physicist and Oxford Photovoltaics co-founder Professor Henry Snaith and his team, charts the development of alternatives to crystalline silicon photovoltaics, describing how the original ‘new generation’ technology based on organic or dye-sensitised solar cells achieved the semitransparency that is desired by designers and developers of buildings, but was unable to achieve efficiencies close to crystalline technology. Now, however, Professor Snaith and his team at the University have developed solar cells using perovskite. These solar cells have achieved efficiencies over 15% in the last 12 months, overtaking other emerging solar technologies which have yet to break the 14% barrier despite decades of research. Most significantly, the team has also found a solution to the reddish-brown tint previously associated with the use of perovskite to produce neutral coloured, semi-transparent cells which address the needs of the construction industry. This world-leading research is being brought to market by Oxford Photovoltaics (Oxford PV), which holds an exclusive license to the technology. Oxford PV scooped a number of awards for its progress in the commercialisation of the technology during 2013 including the British Renewable Energy Association’s Innovation Award, the UK Business Angels’ Best Early Stage Investment in a Disruptive Technology Business Award and the Solar Award for Excellence: BIPV Innovation at the 2013 Solar UK Industry Awards. In December last year, Nature magazine identified Professor Snaith, Oxford PV’s Chief Scientific Officer, as one of the ten people who made a difference to science in 2013. Commenting on this latest breakthrough he said: 'The pace of development, of this new solar technology, alongside ongoing research into storage solutions, means that photovoltaics will play an increasingly important role in meeting future energy demand globally.'"

"Ten million homes in the UK should have their roofs covered with solar panels in the next six years, if the country is to fulfil its renewable energy potential, energy experts said on Wednesday. That number - of more than a third of households generating energy from the sun - would allow the UK to produce about 6% of its annual electricity needs from solar power, with as much as 40% coming from the panels on sunny days in summer, by 2020. These figures are comparable to those of Germany, which has made a major push on solar power in the last decade. Installing more solar panels brings the costs of the technology down dramatically, because of economies of scale, as the example of Germany and other countries shows. By 2030, the cost of solar should be comparable to that of even the dirtiest forms of coal, and of gas, said Ajay Gambhir, of Imperial College London. Nearly half a million homes in the UK have solar panels installed today, recent figures show. At present, the cost of solar power in Germany is about Euro cents 10 per kilowatt hour, compared with about 6 to 8 Euro cents per kilowatt hour for 'brown' coal – the most carbon-intensive form of the fuel, but also the cheapest – and gas. On current trends that should reduce to 6 to 8 Euro cents per kilowatt hour for solar energy by 2030, while the cost of fossil fuels is expected to stay the same, according to academics from the Grantham Institute at Imperial College London, who published a briefing paper on the subject on Wednesday."

"A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the energy for later use, the researchers say. In this case, adding the extra step improves performance, because it makes it possible to take advantage of wavelengths of light that ordinarily go to waste. The process is described in a paper published this week in the journal Nature Nanotechnology, written by graduate student Andrej Lenert, associate professor of mechanical engineering Evelyn Wang, physics professor Marin Soljacic, principal research scientist Ivan Celanovic, and three others. A conventional silicon-based solar cell "doesn't take advantage of all the photons," Wang explains. That's because converting the energy of a photon into electricity requires that the photon's energy level match that of a characteristic of the photovoltaic (PV) material called a bandgap. Silicon's bandgap responds to many wavelengths of light, but misses many others. To address that limitation, the team inserted a two-layer absorber-emitter device — made of novel materials including carbon nanotubes and photonic crystals — between the sunlight and the PV cell. This intermediate material collects energy from a broad spectrum of sunlight, heating up in the process. When it heats up, as with a piece of iron that glows red hot, it emits light of a particular wavelength, which in this case is tuned to match the bandgap of the PV cell mounted nearby."

"Cloudy Britain is emerging as Europe’s hottest market to build solar parks. Cheaper equipment costs and steady subsidies are attracting developers of large-scale, ground-mounted projects from nations like Germany and Spain that pioneered solar on the continent. Britain may build more big plants — 2 megawatts or larger — than any European country, adding as much as 2,000 megawatts of capacity this year, according to PricewaterhouseCoopers. Those panels would occupy about 16 square miles, enough to cover most of central London. While much of the continent has scaled back solar aid to favor economic growth over green policies, Britain pledged subsidies through 2020 with no limit on the size of projects. Investors raised at least $1.2 billion last year for megawatt-scale projects, according to data compiled by Bloomberg."

"Ford Motor Company, in collaboration with Georgia Tech, debuted a new solar car concept earlier this month at the 2014 International CES in Las Vegas. The C-MAX Solar Energi Concept is a first-of-its-kind hybrid electric vehicle with the potential to free drivers of their dependence on the electric grid. Instead of recharging its battery from an electrical outlet, C-MAX Solar Energi Concept harnesses the power of the sun by parking under a special concentrator that acts like a magnifying glass, directing intensified rays from the sun onto solar panels on the parked vehicle’s roof below. The result is a car that takes a day’s worth of sunlight to deliver the same performance as Ford’s conventional C-MAX Energi plug-in hybrid, which gets combined miles per gallon gasoline equivalent (MPGe), with EPA-estimated 108 city/92 highway/100 combined MPGe. “Ford didn’t just want to build an electric car, but a plug-in hybrid electric car that actually uses green electricity,” said Bert Bras, a professor in the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology in Atlanta. “Just putting photovoltaic cells onto a car is not going to do it, so they reached out to us to help progress the concentrator idea.”"

"Roughly 300 million Indians living in 80 million households — about a quarter of the country’s population of 1.2 billion — do not have access to electricity. According to the World Bank, per capita electricity consumption in India, centered mainly in cities and towns, is 684 kilowatt hours — just 1/20th of the United States’ per capita consumption of 13,246 kilowatt hours. Nearly all microgrids in India are powered by solar photovoltaic panels, with the exception of 20 to 30 networks that run on hydropower in the states of Karnataka and Uttarakhand and the biomass-powered grids operated by Husk. To date, microgrids provide just a tiny fraction of India’s overall power needs. Although no comprehensive statistics exist on the number of microgrids, a conservative count shows that they serve at least 125,000 households in India, divided mostly between large, government-sponsored projects in the North Indian states of Chhattisgarh and West Bengal and private ventures centered on Uttar Pradesh and Bihar. Uttar Pradesh and Bihar are among the most rural and least electrified states in India — a countryside packed with tens of millions of people, united by darkness. India’s Ministry of New and Renewable Energy, through its National Solar Mission, has set the highly ambitious goal of replacing kerosene lamps with 20 million solar lighting systems — powered by microgrids, solar panels on individual homes, or solar lanterns — by 2022. ...By illuminating an entire village at once, a microgrid can spread light more quickly than handouts of solar-powered lanterns. It can also scale up far faster than traditional power lines, which are often promised in India but seldom delivered. By deriving their power from biomass or solar panels, microgrids raise the possibility that large regions could stay off the coal-fired power grid forever, shaving a significant chunk off the world’s future carbon budget. Whoever finds the business model for providing cheap, reliable, local power will help pull 300 million Indians from the 19th century into the 21st century, with vastly expanded opportunities for education and commerce."

"US researchers have made an important step forward in the quest to store electricity from intermittent energy sources such as wind and solar. A Harvard University team came up with a way to drive down the cost of flow battery technology, which is capable of storing energy on large scales - within an electrical power grid, for example. Grid-scale storage for renewables could be a game-changer - making wind and solar more economical and reliable. While flow battery designs are suited to storing large amounts of energy cheaply, they have previously relied on chemicals that are expensive or difficult to maintain, driving up costs. Most previous flow batteries have chemistries based on metals. Vanadium is used in the most commercially advanced flow battery technology, but its cost is relatively high. Other variants contain precious metal catalysts such as platinum. The researchers say their new battery already performs as well as vanadium flow batteries, but uses no precious metal catalyst and has an underlying chemistry that is metal-free, instead relying on naturally abundant, more affordable chemicals called quinones. These water-soluble compounds are organic (carbon-based) and are similar to chemicals that store energy in plants and animals. These molecules are cheap and they're in all green vegetables, as well as crude oil,' said co-author Michael Aziz from the Harvard School of Engineering and Applied Sciences (SEAS) in Cambridge, Massachusetts.... Much like fuel cells, flow batteries store energy in chemical fluids contained by external tanks, instead of within the battery container itself as do the solid-electrode batteries found in cars and mobile devices. '[A flow battery is] similar to a fuel cell in that respect. It stores energy as hydrogen gas outside the fuel cell and when you need to convert that chemical energy into electrical energy, you run it through the fuel cell to make electricity,' Prof Aziz explained. 'The difference with a flow battery is that you need to run it forwards and backwards. You run it backwards to turn the electrical energy into chemical energy and store it in the tanks. Then you run it forwards to get the energy back out, converting the chemical energy back into electricity.' The amount of energy that can be stored by a flow battery is limited only by the size of the tanks and the amounts of storage chemicals that can be afforded, he added. In an accompanying article in Nature, Grigorii Soloveichik, from General Electric Global Research in New York, called the results 'promising', and said the approach 'may serve as the basis for a new flow-battery technology".

"To help remedy India’s situation, two solar septic systems and a lavatory are being shipped from the Caltech campus to India on Tuesday. Using the solar toilet system will provide underdeveloped or impoverished areas a cleaner and healthier way to dispose of human waste without the risk of mixing it with drinking and bathing waters.... According to the World Wide Water Report, 2.5 billion people live without basic sanitation like flushing toilets and latrines, almost one billion of them children. Every 20 seconds, a child dies as a result of poor sanitation. A 20-foot lavatory and treatment system will be sent to Mahatma Gandhi University in Kottayam, Kerala, which will collaborate with Caltech on the solar-powered septic system. A treatment system will be shipped to either Ahmedabad or Trivandrum to be connected to an Eram Scientific 'eToilet,' an energy-saving approach to the toilet. The systems were built three months ago. A third solar toilet will stay at Caltech for further studies, and can be used by anyone on campus. Kohler, a kitchen and bathroom design and technology company, is supporting the efforts by donating plumbing products and design advice...'In 2011, a team of Caltech researchers was awarded a $400,000 grant to create a toilet that would safely dispose of human waste for just five cents per use per day. In 2012, their solar system won first place in the Reinventing the Toilet Challenge sponsored by the Bill and Melinda Gates Foundation. Using solar power, which can be operated remotely, the solar toilet converts sunlight to electricity that powers an electrochemical reactor, which breaks down water and human waste into fertilizer and hydrogen, which can be stored in hydrogen fuel cells. In addition, the waste water can be recycled through the septic system to keep the toilet from contaminating drinking water. 'We’re oxidizing the waste, and we’re also disinfecting it, so we’re killing bacteria,' Cid said."

"The documented savings for people who go solar are enormous. Solar power is surely now saving millions of people billions of dollars. However, generic studies regarding solar savings and even building-specific projections of how much you can save aren’t enough for some people. Generaytor may have a solution for those who need a little more convincing. The company started off by offering its service to IKEA customers in the UK (solar panels are sold at IKEA there), but it has now expanded its service to web users the world over. So, compared to other solar savings projections that companies like 1BOG (with whom we have a partnership) and Cost of Solar (for whom I write) offer, what’s so unique about Generaytor? 'With Virtual Solar, users get a live simulation of their savings, powered by actual data from solar systems of nearby community members,' Generaytor writes. In other words, rather than using entirely generic inputs + your home’s specifics, the service also utilizes the solar data from houses in your area. Additionally, it lets you look at how solar would theoretically perform on your roof in real time. As they say, it’s 'try before you buy' for solar… or something close to it.'"

On many circuits, the utility said, there's so much solar energy that it poses a threat to the system and a safety issue. Studies are needed on whether grid upgrades are necessary. If they are, residents adding solar must foot the bill. And starting immediately, contractors and residents would need permission to connect most small rooftop systems to the grid. The new HECO policy was included deep in the text of emails the Walkers' solar contractor had sent, but it escaped their notice before installation. They're now paying $300 per month on a loan for the panels, plus the $250 electric bill. 'It goes from frustration to outrage,' William Walker, 33, said of his reaction. 'We hear the excuses that HECO provides, that they put out there at least as far as the justification. There's really not a lot of substantiation. My belief is it's purely profit-motivated, to keep people away from PV and keep them on the grid.'...The new struggle on Hawaii foreshadows what the rest of the country could face as solar moves closer to the mainstream, several involved in the debate said."
A Solar Boom So Successful, It's Been Halted
Scientific American, 20 December 2013

"You may have noticed lately that more residences and businesses are being equipped with photovoltaic solar roof panels. The reason is relatively simple: the cost to do so has dropped dramatically over the past five years. The cost of installing photovoltaic solar arrays has dropped to $3 per watt of electricity they produce - about the same as coal-powered plants cost to build - creating a watershed moment in the development of clean energy, experts say. The average price of a solar panel has declined by 60% since the beginning of 2011, according to GTM Research. And, according to CleanTechnica, a website dedicated to renewable energy news, the price of solar power has fallen rom $76.67 per watt in 1977 to 74 cents today. This year, solar power was the second leading source of new electricity, according to CleanTechnica. The amount of power produced by solar arrays in the U.S. is skyrocketing as installations soar. This year, it's expected that the amount of power solar arrays produce will be equal to that of 10 nuclear power plants or 10 gigawatts (a GW is equal to 1 billion watts), according to GTM. As a whole, the U.S. installed 4.3GW of PV solar arrays this year, a 27% increase over 2012."

"Israel’s foremost green energy pioneer is visiting London next week, where he will propose, among other innovations, a 'renewable energy' solution to the Iranian crisis. 'Nuclear power is the power of war and solar power is the power of peace,' said Yosef Abramowitz, who has set up massive solar fields in Israel’s Negev desert.  'If the Iranian government says it is concerned about having electricity for its people, no one so far has either called its bluff or helped it towards cheap energy that is greener.' Mr Abramowitz will argue at a meeting in Parliament that the West should try to end the nuclear crisis with Iran by offering to help it develop large-scale green energy capabilities. He acknowledged that his idea is unorthodox, but said he thinks there is a 'diplomatic opening' for it."

"A Japanese construction firm is proposing to turn the moon into a colossal solar power plant by laying a belt of solar panels 250 miles wide around its equator and beaming the energy back to Earth by way of lasers or microwave transmission. The 'Luna Ring' that is being proposed would be capable of sending 13,000 terawatts of power to Earth - more than three times more than the United States generated throughout the whole of 2011. Shimizu is reluctant to put a price tag on the construction costs involved but, given adequate funding, the company believes construction work could get under way as early as 2035. Robots and automated equipment would be developed to mine the moon’s natural resources and produce concrete and the solar cells required for the scheme. Shimizu believes that “virtually inexhaustible, non-polluting solar energy is the ultimate source of green energy”. "

"Fracking is not going to reduce gas prices in the UK, according to the chairman of the UK's leading shale gas company. The statement by Lord Browne, one of the most powerful energy figures in Britain, contradicts claims by David Cameron and George Osborne that shale gas exploration could help curb soaring energy bills. Browne added to the government's ongoing troubles over energy policy by labelling nuclear power as 'very, very expensive indeed' and describing the fact that more state subsidies are given to oil and gas than to renewable energy as 'like running both the heating and the air conditioning at the same time'. The former chief executive of BP, who now holds a senior government position as lead non-executive director, told an audience at the London School of Economics that climate change was 'existentially important', but that without gas the transition to a zero-carbon energy system would never happen. However, Browne, who is the chairman of fracking company Cuadrilla, said: 'I don't know what the contribution of shale gas will be to the energy mix of the UK. We need to drill probably 10-12 wells and test them and it needs to be done as quickly as possible.' 'We are part of a well-connected European gas market and, unless it is a gigantic amount of gas, it is not going to have material impact on price,' he said..... Browne criticised the UK's fossil fuel subsidies: 'In 2011, the UK spent over £4bn supporting the production and consumption of oil and gas, more than they spent to support renewable energy.' Across the OECD, he added, $80bn every year is spent supporting production of carbon-based fuels: 'It is like running both the heating and the air conditioning at the same time,' he said..... Browne said nuclear power was one of the safest energy sources available, but said that had come at a cost: 'Nuclear power has become very, very expensive indeed.' In October, ministers agreed a deal to pay French state energy company EDF billions of pounds in subsidies if it goes ahead with two new reactors at Hinkley Point in Somerset, a deal that left some analysts 'flabbergasted' at the cost. Browne also said the siting of new reactors on the coast when sea level and storm surges are rising was a 'big issue' and that they must be made resilient. Lord Adair Turner, the former chairman of the Financial Services Authority and Committee on Climate Change, introduced Browne's lecture and agreed that the cost projections for nuclear power were 'disappointing' compared to a 2008 analysis he led. Turner said that in contrast, solar power costs had fallen 'beyond our wildest dreams' by about 80% in five years.' Browne, once known as the 'sun king' and who said he is now co-head of the largest private equity renewable energy fund in the world at Riverstone Holdings, said: 'Solar is a very good technology and we should use more of it.'"

"If anybody doubts that federal energy regulators are aware of the rapidly changing electricity landscape, they should talk to Jon Wellinghoff, chairman of the Federal Energy Regulatory Commission (FERC). 'Solar is growing so fast it is going to overtake everything,' Wellinghoff told GTM last week in a sideline conversation at the National Clean Energy Summit in Las Vegas. If a single drop of water on the pitcher’s mound at Dodger Stadium is doubled every minute, Wellinghoff said, a person chained to the highest seat would be in danger of drowning in an hour. 'That’s what is happening in solar. It could double every two years,' he said. Indeed, as GTM Research's MJ Shiao recently pointed out, in the next 2 1/2 years the U.S. will double its entire cumulative capacity of distributed solar -- repeating in the span of a few short years what it originally took four decades to deploy."

"In a first for the solar power industry, Wall Street is dealing with bonds backed by solar electricity payments. SolarCity, a provider of energy services, plans to sell the bonds, secured by its residential and commercial power contracts. The offering will be managed by Credit Suisse and has received an investment-grade classification of BBB+ from Standard and Poor’s. The bonds will have a yield of 4.8 percent, a relatively high rate that rewards investors for buying untested securities, and will be sold initially to select institutional investors. The solar industry needs new sources of financing. To date, it has relied on tax equity investments and has not been able to draw on capital from public markets. In its preliminary rating report, S&P outlined the risks of the industry’s limited operating history as well as uncertainty about the future of tax credits: the federal tax credit for solar energy projects is set to drop to 10 percent from 30 percent at the end of 2016. Other risks were identified, such as quickly evolving technology and changing utility rates. But S&P also pointed out benefits to the bonds, such as the inclusion of extra collateral, a special reserve account to cover equipment failures, and a shortened, 13-year bond term. In conclusion, S&P stated that it expected the market to continue to grow rapidly. This bond offering is an important step toward financial sustainability as we move toward an energy future powered by renewable sources."

"Saudi Arabia has long been known for its oil. According to Oil and Gas Journal, Saudi Arabia has almost 265 billion barrels of proven oil reserves or around one-fifth of the world's oil reserves. Those oil riches afford Saudi citizens one of the highest living standards in the Middle East with a purchasing power parity per capita of $31,800 per year. With the trend of increasingly affordable solar, Saudi Arabia may soon be known for solar as well. According to Reuters, Saudi Arabia plans to install 41 gigawatts of solar power over the next 20 years from the current 12 Megawatts of capacity today. To put that in perspective, according to the European Photovoltaic Industry Association, the entire continent of Europe had 70 gigawatts of solar installed at the end of 2012."

"Solar panels work great, as long as the sun is shining. This is not some esoteric problem. Solar's intermittency boosts its overall cost because utilities can only depend on a small portion of a panel's generational capacity. The good news is that grid operators realize that pumped hydro storage is tried and tested, offering grid scale storage and a straightforward path for more reliance on solar. Pumped hydro storage transfers water between two reservoirs, allowing the water to flow downhill and make electricity when prices are high. Back in the 1890s Italy and Switzerland were already using pumped hydro storage, and it currently represents around 3% of global generation capacity. More storage facilities are already being built to help handle the new solar farms in America's Southwest. The 1,300 megawatt (MW) Eagle Mountain facility was recently approved with a price tag of $1.4 billion. The operator will be able to release energy during times of peak demand, helping California meet its renewable energy goals."

"Toward the end of last year, installed global photovoltaic generating capacity passed the milestone of 100 gigawatts — enough to meet the energy needs of 30 million households and save more than 53 million tons of carbon dioxide emissions annually, according to a recent report by the European Photovoltaic Industry Association, E.P.I.A., a solar power industry lobby group. 'Right now, today, the world has installed 130 gigawatts of PV, up from 1.4 gigawatts in 2000,' Wolfgang Palz, a former manager of the European Commission’s development program for renewable energies, told a conference organized by France’s National Center for Scientific Research, CNRS, in Paris last month. Europe alone now has 80 gigawatts of installed photovoltaic capacity, of which 35 gigawatts is in Germany, the European Union leader, providing about 7 percent of the country’s electricity, he said. Some regions of Germany are even further ahead: 'If you buy an Audi today, manufactured in Bavaria, 10 percent of the electricity used to produce it is PV,' Mr. Palz said in an interview. With large-volume installation, economies of scale have substantially reduced unit costs. According to a report by the E.P.I.A., the European solar industry’s lobby group, photovoltaic costs have dropped 22 percent with every doubling of production capacity. Going back 10 to 15 years, 'we had to fight to find some crazy people who would install solar panels for $70 per watt on the rooftop,' said Eicke Weber, director of the Fraunhofer Institute for Solar Energy Systems, in Freiburg, Germany.  'We had to find some market support systems for the first thousand-roof program,' Mr. Weber said. 'That became the 100,000-roof program — and then the million-roof program.'  Now, 'the number that should be broadcast is that, in Germany now, we are able to put PV systems on the rooftop for one euro per watt,' or $1.34, 'with the back-up system, with the inverter, and with the cost of installation,' Mr. Weber said. An inverter is a device that converts the direct current electricity produced by solar generation into alternating current that can be fed into the electrical grid. “In other countries, in the United States, it’s about a factor of two to three more expensive,” he added."
Solar Power Begins to Shine as Environmental Benefits Pay Off
New York Times, 11 November 2013

"American innovators still have some cards to play when it comes to squeezing more efficiency and lower costs out of silicon, the workhorse of solar photovoltaic (PV) cells and modules worldwide. A recent breakthrough - the product of a partnership between manufacturer TetraSun and the Energy Department's National Renewable Energy Laboratory (NREL) - could spark U.S. solar manufacturing when the approach hits the assembly line next year. The innovative design, simple architecture, and elegant process flow for fabricating the cells make the technology a prime candidate for large-scale production. Solar industry leader First Solar acquired TetraSun in April 2013, about the time R&D Magazine honored TetraSun and NREL with one of its coveted R&D 100 Awards for the year's top innovations. Typically, silicon PV cell manufacturers add a grid of thin silver lines to the cell via a screen-printing process to form the front contacts. The TetraSun cell instead loads 50-micron-wide copper electrodes on its front contacts in a way that prevents diffusion of the metal-which can degrade performance. The new process exceeds the performance of traditional heterojunction cells without the need of any special equipment, complicated module assembly, or costly transparent conductive oxides. That adds up to a significant cost advantage when it comes to high-volume manufacturing. 'It's a potentially disruptive technology, and that's why we decided to work with TetraSun,' said NREL's Martha Symko-Davies, who headed the Energy Department's SunShot Initiative PV Incubator program when TetraSun received a grant from it back in 2010. 'The Incubator program supports potentially disruptive innovations from small startups.'"
New Solar Cell Is More Efficient, Less Costly

"The sound vibrations that make up music can make solar panels work harder, according to new research, and pop music performs better than classical.Scientists showed that high pitched sounds like those common in pop and rock music caused the greatest improvement in the solar cells' power output, increasing it by up to forty per cent. Classical music, with typically lower pitched sounds, still increased the cells' output, but not as much.This discovery makes it possible to power a wider range devices with solar energy than at present, as scientists can improve the efficiency of solar cells using the ambient, or background, noise present in many environments. The study is published today by LCN researchers at Imperial College London and Queen Mary University of London, in the journal Advanced Materials. They found that sound levels as low as 75 decibels (equivalent to a typical roadside noise or a printer in an office) could significantly improve the performance of the solar cells tested in the study. Practical uses for this discovery could include solar powered air conditioning units, laptop computers or electronic components on buses, trains and other vehicles... 'After investigating systems for converting vibrations into electricity this is a really exciting development that shows a similar set of physical properties can also enhance the performance of a photovoltaic solar cell,' said Dr Steve Dunn, Reader in Nanoscale Materials from Queen Mary’s School of Engineering and Materials Science. 'The work highlights the benefits of collaboration to develop new and interesting systems and scientific understanding,' he added."

"Sunlabob Renewable Energy and Fondation Energies pour le Monde this week announced the completion of a solar-powered mini-grid that is now delivering reliable, affordable electricity to nearly 500 people in a remote village in Luang Prabang Province, Laos. Ban Houaypha, a village of 83 households, has limited job opportunities, low income levels, inadequate education and health services and no short-term outlook to receive electricity from the national electricity grid. The average household income is less than $2.50 a day. The 6.5 kWp solar plant will distribute electricity through a decentralized village grid to households, a community center and five street lights. The Ban Houaypha mini-grid is the first step within the Fondation’s long-term rural electrification strategy in Laos that aims to implement 15 solar village grids to provide energy access to at least 10,000 rural Laotians and contribute to the Lao Government’s target of 90% electrification by 2020."

"Sitting on a rooftop, soaking up sun, the humble solar panel may not look like a threat to a multibillion-dollar industry. But some electric utility executives say it is. They even have a name for the nightmare scenario solar could create - the 'death spiral.' They fear solar's rapid spread across homes and businesses, combined with the increasing efficiency of modern buildings and appliances, could slowly erode the utilities' ability to grow. California utilities get paid based on the value of the assets they own - the transmission lines, substations and wires. As more businesses and homeowners generate their own electricity, the utilities won't need to add as many of those assets as before. At the same time, the costs of maintaining the electricity grid might fall on fewer and fewer nonsolar utility customers. The companies could compensate by tacking on fixed monthly charges for all customers, solar and nonsolar alike. But those new charges would jack up bills, and that could prompt more people to slap panels on their roofs. The problem will only get worse if advanced battery packs become cheap enough for home use, parked in the basement by the water heater. Mike Florio, a member of the California Public Utilities Commission, remembers listening to an irate solar homeowner at a hearing in San Diego, where utility executives had proposed a fixed charge. 'A gentleman came up and said, 'Well, I put in solar, and now the utility wants to hit me with a fixed charge,' ' Florio said. ' 'Guess I'll just put in storage with solar and get off the grid altogether.' That's the death spiral. That's what we don't want.' Most everyone who uses the term death spiral quickly acknowledges that it's overblown. Solar installations are spreading at breakneck speed, with another added somewhere in the nation every four minutes, says the Solar Energy Industries Association. But the number of systems is still small, estimated by GTM Research to reach 399,111 by year's end. Most of those systems will be in California."

"All indications are that electric vehicles will rapidly come into common use. The major problems have been the cost, cruising ranges that are less than what we are used to, the time it takes to recharge batteries, and for many, a place to do the recharging. During the last six months there have been dozens of announcements by companies and laboratories around the world concerning the improvement in battery and occasionally ultra-capacitor technology. Many of these speak of 4-5 fold increases in potential energy density of their new electricity storage devices. While most of these are still at the laboratory-bench stage, a few appear ready for commercial application in the next few years or at least before the end of the decade. In August, the Department of Energy announced that it will award $36 million to spend on 22 projects aimed at accelerating the development of better energy storage systems that will speed the adoption of electric vehicles. The era of the electric vehicle is much closer with a dozen or so models from different manufacturers likely to be on the market within the next year. These are coming from manufacturers in the U.S., Europe and the Far East. BMW, Mercedes and VW will have high quality vehicles with ranges in excess of 100 miles on the market next year. Rapid charging that will boost a battery to 80 percent of capacity or less in 20 minutes is being tested as are methods of charging a vehicle simply by stopping over a device on the ground. Similar progress is being made for light trucks and buses. The Koreans are testing a bus that recharges its electric batteries from wires buried beneath its route as it is moving. This allows for smaller and cheaper battery packs and the ability to move the bus off its designated route. Forecasters are starting to take notice of these developments and making what they consider bold predictions that sales of electric-powered cars might reach 400,000 vehicles ten years from now."

"Significant improvements to the efficiency of solar cells could be possible in the near-future thanks to the recent development of a new heat-resistant thermal emitter by researchers at Stanford University. The new heat-resistant thermal emitter was created as a means of converting the higher-energy portion of light into lower energy waves which can then be absorbed by the solar cells and converted into electricity, along with the lower energy portions that most solar cells convert. Technologies such as this — more broadly known as thermophotovoltaics — have been around for quite some time, but have, until now, possessed a number of important limitations that this new device seems to overcome. Foremost of which, are the limitations to do with operating temperature ranges — earlier designs have all become nonfunctional at temperatures of around 2200 degrees Fahrenheit, whereas the new one “remains stable at temperatures as high as 2500 F”..... 'These results are unprecedented,' stated lead author Kevin Arpin. 'We demonstrated for the first time that ceramics could help advance thermophotovoltaics as well other areas of research, including energy harvesting from waste heat, high-temperature catalysis and electrochemical energy storage.' 'We’ve demonstrated that the tailoring of optical properties at high temperatures is possible,' Braun added. '[Hafnium and tungsten are abundant, low-cost materials, and the process used to make these heat-resistant emitters is well established. Hopefully these results will motivate the thermophotovoltaics community to take another look at ceramics and other classes of materials that haven’t been considered.' The new research was just published in the October 16th edition of the journal Nature Communications."
Vastly Improved Solar Cells Possible With Use Of New Heat-Resistant Materials

"Concentrated solar thermal is again making the news, with the world’s largest parabolic trough array with thermal storage – opening for business in Arizona. The 280 MW Solana Generating Station constructed by Spanish group Abengoa has six hours of molten storage capacity that will allow it to produce energy into the evening, and deliver output according to the needs of the customer. 'Solana is a monumental step forward in solar energy production,' said Don Brandt, the president of APS, the local utility. 'This provides a huge boost toward our goal to make Arizona the solar capital of America.' The opening of Solana is one of three major new projects that are coming on stream, as CSP begins to recover the ground lost, and projects ceded, to solar PV when that technology delivered massive cost reductions in recent years. The 375 MW Ivanpah project, the largest solar power tower in the world, has delivered to the grid for the first time and is due to start full operations within the next few months, as is the 110 MW Crescent Dunes facility in Nevada, which will be the world’s largest solar power tower project with molten salt. Also, the first commercial scale solar thermal plant with storage, the Gemasolar plant in Spain, recently marked its second anniversary by delivering electricity 24/7 for 36 consecutive days. On Thursday, Dr Keith Lovegrove, the head of solar thermal at Australia’s IT Power, said CSP with storage is ”virtually unbeatable” as a technology, and the costs are coming down quickly. The Solana plant’s CSP technology produces electricity by collecting the sun’s heat to create steam that turns conventional turbines. It has 2,700 parabolic trough mirrors,which follow the sun to focus its heat on a pipe containing a heat transfer fluid. This fluid, a synthetic oil, can reach a temperature of 735 degrees Fahrenheit. The heat transfer fluid then flows to steam boilers, where it heats water to create steam. The steam drives two 140 MW turbines to produce electricity, much like a traditional power plant."

"A novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source while improving the efficiency of wastewater treatment. A research team led by Yat Li, associate professor of chemistry at the University of California, Santa Cruz, developed the solar-microbial device and reported their results in a paper published in the American Chemical Society journal ACS Nano. The hybrid device combines a microbial fuel cell (MFC) and a type of solar cell called a photoelectrochemical cell (PEC). In the MFC component, bacteria degrade organic matter in the wastewater, generating electricity in the process. The biologically generated electricity is delivered to the PEC component to assist the solar-powered splitting of water (electrolysis) that generates hydrogen and oxygen."

"Last week there were two announcements related to innovation in increasing solar PV efficiency. Both are from a team of companies rather than individual company. In the established silicon PV cell domain imec, RENA, and SoLayTec have achieved solar PV cell efficiency of 20.1% on a Passivated Emitter and Rear Cells (PERC) type silicon solar cells, which are made using atomic layer deposition (ALD) Al2O3 passivation and standard screen printed contacts. These silicon solar cells are manufactured on imec’s silicon solar cell pre-pilot line using RENA’s InPilot tool for rear-side polishing and emitter removal, and SoLayTec’s spatial ALD tool for Al2O3 deposition. A top efficiency of 20.6% was reached when applying Cu-plated contacts at the front instead of silver screen printed contacts. ALD Al2O3 passivation process by SolaYTec is aimed at lower cost of ownership (< 2€ct/layer) without effecting the cell efficiency, which is ready to be implemented in an industrial environment. While silicon-based solar PV getting better, researchers are exploring III-IV group semiconductor materials to develop high-efficiency solar cells for concentrated solar photovoltaic applications. The CPV is suitable for areas where sunlight intensity is very higher. In another announcement on solar PV efficiency achievement, The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin have jointly achieved a new record efficiency of 44.7%. Scientists have used multi-junction solar cells to achieve increased efficiency, several cells made out of different III-V semiconductor materials are stacked on top of each other. Each material is designed to convert light radiation into electricity for different wavelengths such as infrared, ultraviolet and visible light. Multiple semiconductor wafers were bonded one over the other."
Solar PV cell efficiency taken to new levels

"Solar power is here, and it isn’t just environmentalists saying it anymore. A research division of Citigroup, the massive multinational bank that probably doesn’t share Greenpeace’s worldview on many issues, does agree with us on one point: solar energy is poised to explode in the U.S. Citi Research published the report, 'Rising Sun: Implications for U.S. Utilities,' in August (hat tip to Marc Gunther, who referenced it in a great piece for Yale Environment 360.) It slipped under the media radar, which is unfortunate because the analysis is phenomenal and offers great hope for the clean energy revolution here in the U.S. Citi’s analysts don’t mince words: 'Our viewpoint is that Solar is here to stay and very early in the growth cycle in the U.S.' They note that solar panels costed an average of $75/watt in 1972. In 2012, that number was down to less than $1/watt (the number is even lower now, closer to $.65/watt in some places.) The report compares that rapid decrease in cost to Moore’s Law, the famous theory which postulated in 1965 that computer chips could double in performance every two years. That prediction turned out to be uncannily accurate, which is the basic reason for why you’re reading this on a laptop, tablet or smartphone right now. A similar phenomenon is happening now with solar costs, which have shrunk reliably and quickly. As a result, two thirds of all the solar power in the world has been installed since 2011, and that number will double again by 2015, Greentechmedia reported. Citi’s analysts noted that this solar growth has exceeded almost everyone’s expectation: 'The biggest surprise in recent years has been the speed at which the cost of solar panels has reduced, resulting in cost parity being achieved in certain areas much more quickly than was ever expected.' The most exciting thing about this solar boom is probably the hope that it provides for everyone who depends on a healthy planet (AKA, everyone.) Solar growth means less burning of coal, gas and eventually oil, the main causes of the climate change that is already causing extreme weather here in the U.S. and around the world, and portends much uglier effects like increased conflict, rising sea levels, ocean acidification and fresh water scarcity down the road.'"

"A new world record has been set for solar hydrogen production efficiency — the new record-breaking efficiency of 5.3% blows past the previous record of 4.2%, thanks in large part to the development of a new 'wormlike' hematite photoanode. The new photoanode was developed by researchers from the Ulsan National Institute of Science and Technology (UNIST) in South Korea, and from the University of Tokyo in Japan. The impressive jump from a record efficiency of 4.2% to 5.3% was achieved by the researchers through the utilization of an entirely new method/different materials — whereas the previous record was set by researchers (from the Ecole Polytechnique de Lausanne in Switzerland) using stable oxide semiconductor photoanodes, the new record was set via the use of the new worm-like hematite photoanode."

"For the first time, more solar will be added to the world's grid this year than wind. About 36.7 gigawatts (GW) of solar is expected to be installed this year compared to 33.8 GW of onshore wind and 1.7 GW of offshore wind, says Bloomberg New Energy Finance. That's because this is the worst year for wind installations since 2008 - down 25% - largely because of policy uncertainty in the US and China. Last year, new wind capacity totaled 46.6 GW, much more than solar at 30.5 GW - but both were record figures.  Going forward, wind and solar PV are expected to grow neck-in-neck through 2030 - expanding at about the same rate, says New Energy Finance. Wind is expected to grow from 5% of the world's total installed capacity in 2012 to 17% in 2030. Solar PV is projected to grow from 2% today to 16% of world energy generating assets by 2030."

In other words, most of the solar power systems installed at homes in California are owned by someone other than the homeowner. The EIA’s analysis, which relied on data from the California Solar Initiative, provides still more evidence of a maturing third-party financing market for solar PV projects. While the CSI data is limited to California, other industry reports have shown similar growth trajectories for third-party-owned residential solar PV systems in other states."

"Developers installed 832 megawatts of solar power capacity in the U.S. in the second quarter, led by large projects that sell electricity to utilities, a trade group said. Installation grew 15 percent from the prior quarter, with flat results in the residential market and commercial demand slumping 11 percent, the Washington-based Solar Energy Industries Association said today in a statement. Utility-scale projects increased 42 percent. The U.S. will probably install 4.4 gigawatts of solar power this year, up 30 percent from 2012, as demand increases for residential rooftop systems and the pipeline of utility-scale projects increases, according to Shayle Kann, vice president of research in Boston at GTM, which wrote the report with SEIA."
U.S. Solar Power Rises 15% on Large Scale Power Projects
Bloomberg, 12 September 2013

"Today’s solar industry is puny – it supplies less than 1 percent of the electricity in the U.S. – but its advocates say that solar is, at long last, ready to move from the fringe of the energy economy to the mainstream. Photovoltaic panel prices are falling. Low-cost financing for installing rooftop solar is available. Federal and state government incentives remain generous. Yet opposition from regulated utilities, which burn fossil fuels to produce most of their electricity, could stop a solar boom before it gets started.  Several utilities, including Arizona Public Service and Denver-based Xcel Energy, have asked their state regulators to reduce incentives or impose charges on customers who install rooftop solar; so far, at least, they aren’t making much headway. A bill in the California legislature, backed by the utility interests would add $120 a year in fees to rooftop solar customers.  But other utility companies are adopting a different strategy – they are joining forces with solar interests. NRG Energy, based in Princeton, N.J., has created a rooftop solar unit to sell systems to businesses and, eventually, homeowners. New Jersey’s PSE&G is making loans to solar customers, and Duke Energy and Edison International have invested in Clean Power Finance, a San Francisco-based firm that has raised half a billion dollars to finance solar projects.   'The industry is divided on how to deal with the opportunity – or threat,' says Nat Kreamer, Clean Power Finance’s CEO. 'Some utilities are saying, how do I make money off distributed solar, as opposed to, how do I fight distributed solar.'
With Rooftop Solar on Rise, U.S. Utilities Are Striking Back
Yale Environment 360, 3 September 2013

"A new tax on solar power introduced two weeks ago by the Spanish government has been described as 'ludicrous' and 'stupid' in two leading international publications. US business and finance magazine Forbes pulled no punches in an article titled, 'Out of ideas and in debt, Spain sets sights on taxing the sun'. It pointed out that Spain 'is one of the top countries in the world with respect to installed photovoltaic (PV) solar energy capacity.' But the author took an incredulous tone and noted: 'Spain is now attempting to scale back the use of solar panels – the use of which they have encouraged and subsidized over the last decade – by imposing a tax on those who use the panels.'"

"The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity needs of nearly 70 million people at the European level of use. While PV production has become increasingly concentrated in one country—China—the number of countries installing PV is growing rapidly. In 2006, only a handful of countries could boast solar capacity of 100 megawatts or more. Now 30 countries are on that list, which the International Energy Agency (IEA) projects will more than double by 2018."

"China has raised its 2015 target for solar-electricity capacity, giving a shot in the arm to its solar companies, many of which are struggling due to industry overcapacity, slow global demand and overseas trade disputes. China’s State Council, or cabinet, in a statement dated July 4 but posted Monday said installed capacity for solar electricity would reach more than 35 gigawatts by 2015, and would grow by about 10 gigawatts a year between now and then. China’s previous target was 21 gigawatts, and its installed capacity in 2012 was about 7 gigawatts."
China Raises Target For Solar Power Capacity
Wall St Journal (blog), 15 July 2013

"Britain's new support plans for renewable energy confirm that offshore wind is the most expensive green power technology, raising the question why the country is placing so much faith in it. Offshore wind is even more expensive than solar power, which is not an energy technology where Britain has a competitive advantage, as a northern country whose climate is dominated by wet Atlantic weather. The country has one of the best wind resources in Europe, which has led to a belief by some that it makes more sense to invest in offshore wind. Such thinking is muddled because solar power is cheaper, even in Britain, and will probably remain so. Britain announced support rates on Thursday for the second half of the decade which would provide offshore wind with a 20-25 per cent premium to solar power. The premium was even greater compared with other low-carbon technologies including onshore wind, biomass, waste-to-energy and hydropower. That is before accounting for the astronomical grid connection cost for offshore wind - by sub-sea cable. This cost, about 10 times that for rival electricity generation technologies, is subsidised separately and is far from transparent. The evidence for higher costs is a concern for Britain's plans, confirmed on Thursday, to install more offshore wind capacity than any other renewable power technology by 2020. The government says it supports offshore wind because of its potential to help generate thousands of jobs, and to improve Britain's security of energy supply with low-carbon power....Under the new system of support, offshore wind will qualify for a strike price of 155 pounds per megawatt hour (MWh), from 2014/2015, while large-scale solar photovoltaics will get 125 pounds, and onshore wind 100 pounds. The rate for offshore wind is higher than any other technology, with the exception of an experimental waste-to-energy process called pyrolysis, and marine wave and tidal projects. Offshore wind will continue to earn the highest level of subsidy - with the exception of wave and tidal - through 2018/2019. (See Chart 1) The difference with pyrolysis, wave and tidal power is that these are unproven and experimental, and will therefore see negligible capacity installed by 2020 - an aggregate of about 0.4 gigawatts, according to the DECC figures. By contrast, offshore wind will see the most capacity installed of any renewable technology, at 8-16 GW. The logic of selecting the most expensive technology for the largest deployment is unclear. It may be that DECC expects the costs of offshore wind to plummet shortly thereafter, but that expectation is not demonstrated."

"Most efforts at improving solar cells have focused on increasing the efficiency of their energy conversion, or on lowering the cost of manufacturing. But now MIT researchers are opening another avenue for improvement, aiming to produce the thinnest and most lightweight solar panels possible. Such panels, which have the potential to surpass any substance other than reactor-grade uranium in terms of energy produced per pound of material, could be made from stacked sheets of one-molecule-thick materials such as graphene or molybdenum disulfide. Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering at MIT, says the new approach 'pushes towards the ultimate power conversion possible from a material' for solar power. Grossman is the senior author of a new paper describing this approach, published in the journal Nano Letters.... Pound for pound, he says, the new solar cells produce up to 1,000 times more power than conventional photovoltaics. At about one nanometer (billionth of a meter) in thickness, 'It’s 20 to 50 times thinner than the thinnest solar cell that can be made today,' Grossman adds. 'You couldn’t make a solar cell any thinner.' This slenderness is not only advantageous in shipping, but also in ease of mounting solar panels. About half the cost of today’s panels is in support structures, installation, wiring and control systems, expenses that could be reduced through the use of lighter structures. In addition, the material itself is much less expensive than the highly purified silicon used for standard solar cells — and because the sheets are so thin, they require only minuscule amounts of the raw materials."

"An expert here believes that the Kingdom is likely to spend all its oil on electricity in the country by 2031 if current consumption continues, and has called for an urgent program to harness solar energy. 'There must be real work done to benefit from this alternative energy in the Kingdom in light of climat changes, population growth and increasing electricity use,' said Abdel Malik Al-Junaidi, chairman of the mechanical engineering department at King Abdul Aziz University. He said Saudi Arabia has a 'real wealth' of alternative energy but has not exploited it. He said Saudi Arabia could become a leading exporter of solar power. The Kingdom has this potential because it is located close to the equator, its skies are cloud-free and because the sun's rays fall vertically onto the country. 'Solar energy generation can be 1,000 watts for every square meter which requires stations to transfer this solar energy to electrical energy. (This is important) especially since Saudi Arabia by 2031 will need to use all its oil for electricity production.' Al-Junaidi said that Saudi Arabia has "the highest consumption of electricity in the world.” He said Saudi Arabia has become dependent on oil for its electricity because of the low production costs involved. In contrast, there is a fivefold increase in costs for solar power stations. However, the cost will be much less over the long term, beating traditional sources. He said there was too much electricity consumption in the Kingdom, with the Saudi Electricity Company producing 50GW. In comparison, dams only produce 2GW. There are 25 dams used for electricity generation in the Kingdom."

"Ambulance service vehicles in the south of England have become the first in the country to be fitted with solar panels. Thirty-six rapid response vehicles from the South Central Ambulance Service have been fitted with the panels following a nine-month trial last year. The panels, on the single-crewed cars, help power life-saving equipment and will now be trialled on larger double-crewed ambulances. The ambulances cover Buckinghamshire, Berkshire, Oxfordshire and Hampshire. The solar panels charge the emergency vehicle's secondary battery which powers on-board equipment such as defibrillators, satellite navigations systems and communication devices. Before, ambulances had to let their engines run idle while on standby between emergency calls in order to keep the equipment charged. The idea has come from within the south ambulance service itself as its engineers sought ways of reducing its carbon footprint and fuel costs. It cost £34,560 in total to fit the vehicles with the panels, but the service anticipates reducing its carbon dioxide emissions by 30.28 tonnes and its fuel costs by more than £50,000 over the next five years."

'Theoretically,' said its pilot, Bertrand Piccard, 'the plane can fly forever.' The Swiss-made Solar Impulse is in the middle of a U.S. tour this month, flying five legs from California to New York. In 2015, Piccard and his co-pilot, Andre Borschberg, hope to make the next generation of Solar Impulse the first solar-powered plane to circle the globe."

"In February, California, which mandates that 33% of its electricity come from renewable sources by 2020, required a Los Angeles-area utility to ensure some capacity comes from energy storage. On May 1, Germany, which is shuttering its nuclear power plants as it boosts renewables, began subsidizing homeowners' purchases of batteries to store power from solar panels. China's five-year plan calls for 5% of all electricity to be stored by 2020. In the United States, about 2% of electric capacity is pumped hydro storage, the most common form of energy storage. The global market for storing power from solar panels is forecast to explode, from less than $200 million in 2012 to $19 billion by 2017, according to a report this month by IMS Research. One factor driving this growth is the plummeting price of renewables, especially solar panels that have fallen at least 60% since the beginning of 2011. As a result, industry groups report historic growth as U.S. electric capacity from solar panels jumped 76% and from wind turbines, 28%, last year alone.... Toyota's Jaycie Chitwood said lithium-ion batteries are just too expensive to make electric cars cost competitive without subsidies. Speaking at the Advanced Energy 2013 conference last month in New York City, she said Toyota is expanding its line of electric vehicles to meet the U.S. government's fuel-efficiency targets — not because they're profitable. She said it gives a $14,000 discount for each new electric RAV4. Chitwood said a major battery advance is needed. Toyota is working on several alternatives, including cheaper, longer-range batteries that use magnesium instead of lithium. Commercialization, though, is years away. 'Batteries continue to be a challenge,' especially those for electric vehicles, Esther Takeuchi,chemistry professor at SUNY Stony Brook, said at the same conference. 'Things aren't where we'd want them to be, but they're getting closer.' ... IBM's Allan Schurr is bullish on his company's new lithium-air battery, which takes in oxygen from the air to form a chemical reaction that generates an electric charge. It's lighter and denser than the lithium-ion ones in most of today's electric vehicles, which use heavy metal oxides to drive the chemical reactions that produce power. 'The performance we've seen in tests so far is at or above our expectations,' he says. With 500 miles on a single charge, he says, 'You'd take the 'range anxiety' out of the equation.' The current Nissan Leaf gets up to 75 miles on a single charge, and the Mitsubishi i-MiEV, 62 miles."

"A Vijayawada-based solar energy equipment manufacturer, Jyothi Solar Power Projects has claimed that by using two new technologies together with the existing photo-voltaic (PV) panel system, 91 per cent of the Sun’s energy could be converted into electrical power. At a meeting to showcase the technologies here on Saturday, P. Lakshminarayana, Director-Technical of the company said they had applied for patents. They include ‘Twintin’, a system based on sensors that could synchronise PV panels with the Sun’s movement, thus capturing maximum heat and a Multi-Junctional Device (MJD) with Nano technology that could instantly convert solar energy into electrical power.... In two months, the company’s technical team would prove the technology by generating 40 megawatts of solar power in the presence of scientists from the National Aeronautics and Space Administration, USA. A young scientist with Jyothi Solar Power Projects, Prasanna Kumar said the cost would work out to between Rs. 1 and 1.2 lakh per kilowatt of electrical power produced. Currently, he said between 14 and 16 per cent of solar energy was converted into electrical power in India."

"A project that envisaged supplying solar and wind energy from Morocco to Europe has been shelved. Observers say the question is now whether it will be possible to revive at a later stage. Expectations were running high at the start of November last year for plans to construct a solar and wind power plant in Morocco and export the energy it produced to Europe. Paul von Son, head of the green energy project Desertec Industry Initiative (Dii), had been waiting for a declaration of intent to be signed by Morocco and a number of European countries. 'It would be the first agreement between European and North African governments that regulates the transfer of electricity from renewable sources across national borders,' said von Son at the last Dii annual conference November 2012 in Berlin. That could have been the breakthrough moment for the Desertec project - but in the end, nothing was signed."

"'We're fifteen to twenty years out of date in how we think about renewables,' said Dr. Eric Martinot to an audience at the first Pathways to 100% Renewables Conference held April 16 in San Francisco. 'It's not 1990 anymore.' Dr. Martinot and his team recently compiled their 2013 Renewables Global Futures report from two years of research in which they conducted interviews with 170 experts and policymakers from fifteen countries, including local city officials and stakeholders from more than twenty cities. They also reviewed more than 50 recently published scenarios by credible international organizations, energy companies, and research institutes, along with government policy targets for renewable energy, and various corporate reports and energy literature.  The report observes that '[t]he history of energy scenarios is full of similar projections for renewable energy that proved too low by a factor of 10, or were achieved a decade earlier than expected.' For example, the International Energy Agency's 2000 estimate for wind power in 2010 was 34 gigawatts, while the actual level was 200 gigawatts. The World Bank's 1996 estimate for China was 9 gigawatts of wind and 0.5 gigawatts for solar PV by 2020, but by 2011 the country had already achieved 62 gigawatts of wind and 3 gigawatts of PV."
Conventional Wisdom About Clean Energy Is Still Way Out of Date

"Australian scientists have found a way of hugely increasing the efficiency of solar panels while substantially reducing their cost. The University of NSW researchers have come up with improvements in photovoltaic panel design that had not been expected for another decade. The breakthrough involves using hydrogen atoms to counter defects in silicon cells used in solar panels. As a consequence, poor quality silicon can be made to perform like high quality wafers. The process makes cheap silicon 'actually better than the best-quality material people are using at the moment' the head of the university's photovoltaics centre of excellence, Professor Stuart Wenham, said. Silicon wafers account for more than half the cost of making a solar cell. 'By using lower-quality silicon, you can drastically reduce that cost,' he said. 'We've been able to figure out what the secret is that enables hydrogen to sometimes work the way people want it to, and sometimes doesn't.' At present, the best commercial solar cells convert between 17 per cent and 19 per cent of the sun's energy into electricity. UNSW's technique, patented this year, should produce efficiencies of between 21 per cent and 23 per cent. The price of solar panels has fallen by about 65 per cent in two years, partly due to a huge rise in production in China. Australians have been taking advantage of lower prices, with the number of homes with solar panels exceeding 1 million. The phenomenal growth has caused some casualties in the industry as companies have taken on massive debt to expand supply, then struggled with falling prices in saturated markets. Notable among them is the recent debt default by Suntech Power, once the world's largest solar-panel maker, founded by former University of NSW researcher Shi Zhengrong. Panel prices are predicted to fall much further. European producers predict they will be 60 per cent cheaper by 2020. 'Based on the technological advances we're making, we think that's certainly achievable,' Dr Wenham said."

"In 2007 installed solar power amounted to .0006 of the world's electrical consumption and did not keep pace with the growth of electric consumption. Or as Prieto put it in 2008: 'The Energy Consumption Chariot goes over 200 times faster than the Solar Power horses.' Spain, of course, has gained some fame and notoriety as a global solar pioneer. One-tenth in 2009 and one-fifteenth of the world's installed solar power modules now dot the Spanish countryside. But these expansive operations provide but 4.3 per cent of Spain's electricity....The sun is renewable but photovoltaics are not. Just to make the silicon used to trap the sun's rays on manufactured wafers requires the melting of silica rock at 3,000 Fahrenheit (1,649 Celsius). And the electricity of coal-fired plants or ultrapurified hydrogen obtained from fossil sources provide the heat to do that. It also takes a fantastic amount of oil to make concrete, glass and steel for solar modules.... what troubled Prieto most were the paltry energy returns of some 57,900 solar plants, both big and small. He reviewed Spain's excellent data on the energy outputs of the nation's solar network and than compared those findings to actual energy inputs. To his dismay Prieto found that solar offered only slightly better returns than biofuels. Or 2.4 to one. #That is not enough to maintain society as it is today.' His finding surprised many researchers and for good reason. Previous studies put solar returns as high as eight or even up to 30 to one in some cases, or almost on par with conventional oil. But most of this research used the same sort of best-case scenario modelling typically employed by car industry mileage studies....Prieto calculates.... that to replace all electricity made by nuclear and fossil fuels in Spain would take a solar module complex covering 6,000 sq. km of the country at the cost the entire Spanish budget (1.2 billion Euros in 2007). It would also require the equivalent of 300 billion car batteries to store the energy for night-time use. Prieto is not alone in reaching such sobering conclusions. A 2013 Stanford University report, for example, calculated that global photovoltaic industry now requires more electricity to make silicon wafers and solar troughs than it actually produces in return. Since 2000 the industry consumed 75 per cent more energy than it put onto the grid and all during its manufacturing and installation process."

"Tesla pioneered the idea of harnessing solar power to create an incentive to lure potential customers to its cars. Late last year the Californian startup opened the first of a series of ‘fueling’ stations where owners of its Model S could drive in and charge their batteries to approximately half their charge, for no cost whatsoever. Now BMW, which later this year will launch its first of a new range of electric cars, is announcing a similar concept. Rather than establish its own solar-powered charging stations, BMW will offer owners of its new i range of electric cars an elegant charging system designed to be installed on a garage at their home. The solar-powered home charging system has been developed by fellow German firm Solarwatt and includes a household microgeneration system that can be used to help reduce a home’s power bill."

"Solar power and other distributed renewable energy technologies could lay waste to U.S. power utilities and burn the utility business model, which has remained virtually unchanged for a century, to the ground. That is not wild-eyed hippie talk. It is the assessment of the utilities themselves. Back in January, the Edison Electric Institute — the (typically stodgy and backward-looking) trade group of U.S. investor-owned utilities — released a report [PDF] that, as far as I can tell, went almost entirely without notice in the press. That’s a shame. It is one of the most prescient and brutally frank things I’ve ever read about the power sector. It is a rare thing to hear an industry tell the tale of its own incipient obsolescence....the power generated by solar panels on residential or commercial roofs is not utility-owned or utility-purchased. From the utility’s point of view, every kilowatt-hour of rooftop solar looks like a kilowatt-hour of reduced demand for the utility’s product."

"The excitement over solar power, which once attracted billions in private investment and public subsidies, has waned recently, underscoring the limitations of renewable energies and the unchallenged dominance of fossil fuels. Some of the $75 billion sector's high profile names have fallen on hard times recently – most notably Suntech Power. The China-based solar panel company rattled the industry when it filed for bankruptcy last week. In its heyday, the stock traded just shy of $90 and had a market capitalization of $16 billion: on Thursday, the last day U.S. markets were open, the shares traded around for 42 cents each. Alternative energy advocates point out that Suntech's difficulties were specific to its business model, exacerbated by a trend of compressed industry prices that have squeezed profit margins for solar companies. The company's failure belies a U.S. market where solar panel installations grew by 76 percent last year, according to the Solar Energy Industries Association (SEIA). 'The overall story is about growth and declining costs,' said Arno Harris, chairman of the SEIA Board, in an interview. Much like the way low-cost natural gas is transforming the U.S. energy market, '[solar] costs have come down so dramatically, it's created a Darwinian environment,' Harris added. He pointed to the collapse in silicon – a linchpin of solar panel manufacturing – which has led to a steep drop in prices per watt of solar panels. That amount is now less than a dollar, down sharply from $4 per watt a few years ago, making it difficult for companies to make money. ... SEIA's Harris said that prospects for solar remain bright as renewable energy becomes more mainstream. 'Solar this year will be the number two technology right behind natural gas,' he said. 'It's no longer this fringe thing that's a fun science experiment.'"

Obama said funding research for an Energy Security Trust would help move the nation off oil and 'helps us free our families and our businesses from painful spikes in gas once and for all.'... Obama said the project could create more auto jobs. He pointed to progress by two U.S. automakers: 'Last year, General Motors sold more hybrid vehicles than ever before. Ford is selling some of the most fuel-efficient cars so quickly that dealers are having a tough time keeping up with the demand,' Obama said. 'We're making progress, but the only way to really break this cycle of spiking gas prices, the only way to break that cycle for good is to shift our cars entirely — our cars and trucks — off oil.'"

"The oil-rich sheikhdom of Abu Dhabi this week dedicated what it says is the largest concentrating solar power plant in the world, a sign that Middle Eastern countries are serious about developing their solar resources. The 100-megawatt Shams 1 power plant covers two and half kilometers and generates electricity from over 700 rows of large reflective troughs. Mirrors on the parabolic troughs reflect light onto a tube carrying a synthetic oil, which is converting into steam to turn a conventional electricity-generating turbine. The plant is part of Abu Dhabi’s effort to diversify its energy supply and develop renewable energy technologies for export, says Sultan Ahmed Al Jaber, the CEO of Masdar, the state-owned renewable energy company. 'From precious hydrocarbon exports to sophisticated renewable energy systems, we are balancing the energy mix and diversifying our economy–moving toward a more sustainable future,' Al Jaber says in a statement. The project was developed as a joint venture of Masdar, French energy company Total, and Abengoa Solar of Spain, which has a number of concentrating solar plants around the world. The $600 million project took three years to build and will power thousands of homes. It will use an air-cooling method to condense steam, a water-conserving measure.

"A new technique developed by University of Toronto Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells. In a paper published in the journal Nano Letters, the group describes a new technique to improve efficiency in what are called colloidal quantum dot photovoltaics. It's a technology that already promises inexpensive and more efficient solar cell technology. But researchers say such devices could be even more effective if they could better harness the infrared portion of the sun’s spectrum, which is responsible for half of the sun’s power that reaches the Earth. The solution has an unwieldy name: spectrally tuned, solution-processed plasmonic nanoparticles. These particles, researchers say, provide unprecedented control over light’s propagation and absorption. The new technique developed by Sargent’s group shows a possible 35% increase in the technology’s efficiency in the near-infrared spectral region, says co-author Susanna Thon (pictured left). Overall, this could translate to an 11% solar power conversion efficiency increase, she says, making quantum dot photovoltaics even more attractive as an alternative to current solar cell technologies."

"If the electric car batteries were much cheaper, the range longer, and recharging faster and more readily available, such vehicles just might catch on as an attractive option in the face of ever increasing gasoline costs. This is where the good news comes in, for in the last year what may prove to be highly significant advances in battery technology have been announced and partially verified. These new battery technologies offer the prospects of greatly lowering the cost of batteries, increasing the range of electric cars, and even offering an affordable way of storing intermittent power generated by wind and the sun. The first announcement came in February 2012 from a start-up in California, called Envia, which announced that they had developed a battery cathode made of manganese for lithium ion batteries that would allow electrical energy to be stored at a density of 400 watt-hours per kilogram as compared to 100-180 watt-hours in current batteries. This announcement was followed shortly by one made in March of last year from another California startup, CalBattery, who said they were developing a new lithium ion battery anode material that would allow electric cars to go three times further at a battery life-cycle cost 70 percent less than that of current batteries. Last October CalBattery announced that independent tests had verified that their new silicon-graphene anode material was showing an energy density of 525 watt-hours per kilogram which should clearly allow three times longer ranges for electric cars – provided of course that this new anode material can be introduced into batteries that will last long enough to useful."

"The solar manufacturing industry is now a highly competitive industry. Solar module companies that can’t compete are dropping like icicles on a warm spring day. Shell dropped out of the solar module race in 2006, giving its solar business to SolarWorld. Nonetheless, Shell is still quite bullish on solar energy in the long term. In one of the two future energy scenarios it just released (the New Lens Scenarios), it projected that solar would become the largest source of energy by 2070."

"Buoyed by bullish demand forecasts, and increasing utilization rates and pricing, Deutsche Bank forecasts a solar market transition from subsidized to sustainable in 2014. The German bank has raised its 2013 global solar demand forecast to 30 GW – representing a 20% year-on-year increase – on the back of suggestions of strong demand in markets including India, the U.S., China (around 7 to 10 GW), the U.K. (around 1 to 2 GW), Germany and Italy (around 2 GW). Rooftop installations are, in particular, expected to be a main focus, says Deutsche Bank. A trend for projects being planned with either 'minimal/no incentives' has also been observed, despite the belief that solar policy outlooks are improving, particularly in the U.S., China and India, and 'other emerging markets'. Looking at India, Deutsche Bank predicts that due to state and RPO programs, demand is likely to be strong, at between 1 to 2 GW. Meanwhile, it says, 'grid parity has been reached in India even despite the high cost of capital of ~10-12%.' With system prices between €1,500 to €2,000/kW, net metering for systems below 200 kW and 'advanced' plans for unsubsidized projects in the south of the country, Italy also 'appears to be at grid parity'. 'Assuming small commercial enterprises are able to achieve 50% or more self consumption, solar is competitive with grid electricity in most parts of Italy,' says Deutsche Bank."

"Solar cells made using a process like spray painting have been developed by a research collaboration between scientists at the University of Sheffield. The method could potentially reduce the cost of solar cells significantly meaning the technology could be provided to people in developing countries and perhaps one day be used on glass in buildings or car roofs. Experts from the University of Sheffield’s Department of Physics and Astronomy and the University of Cambridge have created a method of spray-coating a photovoltaic active layer by an air based process – similar to spraying regular paint from a can – to develop a cheaper technique which can be mass produced. Professor David Lidzey from the University of Sheffield said 'Spray coating is currently used to apply paint to cars and in graphic printing. We have shown that it can also be used to make solar cells using specially designed plastic semiconductors. Maybe in the future surfaces on buildings and even car roofs will routinely generate electricity with these materials. We found that the performance of our spray coated solar cells is the same as cells made with more traditional research methods, but which are impossible to scale in manufacturing. We now do most of our research using spray coating. The goal is to reduce the amount of energy and money required to make a solar cell. This means that we need solar cell materials that have low embodied energy, but we also need manufacturing processes that are efficient, reliable and consume less energy.' Most solar cells are manufactured using special energy intensive tools and using materials like silicon that themselves contain large amounts of embodied energy. Plastic, by comparison, requires much less energy to make. By spray-coating a plastic layer in air the team hope the overall energy used to make a solar cell can be significantly reduced."

"Light-trapping, silver nano-antennas could dramatically improve the performance of solar panels by catching more light, according to a new study. A team of physicists, including Professor Constantin Simovski from Finland's Aalto University, has developed theoretical designs that could increase photovoltaic cell efficiency in a commercially viable way. It proposes incorporating chessboard-patterned arrays of tiny silver nano-antennas into solar panels. This would trap more incoming light, allowing it to be preferentially re-radiated through the photovoltaic slab, improving efficiency. New fabrication techniques for printing a nano-antenna array on thin film means it could be done at low cost."

"Using an exotic form of silicon could substantially improve the efficiency of solar cells, according to computer simulations by researchers at the University of California, Davis, and in Hungary. The work was published Jan. 25 in the journal Physical Review Letters. Solar cells are based on the photoelectric effect: a photon, or particle of light, hits a silicon crystal and generates a negatively charged electron and a positively charged hole. Collecting those electron-hole pairs generates electric current. Conventional solar cells generate one electron-hole pair per incoming photon, and have a theoretical maximum efficiency of 33 percent. One exciting new route to improved efficiency is to generate more than one electron-hole pair per photon, said Giulia Galli, professor of chemistry at UC Davis and co-author of the paper. 'This approach is capable of increasing the maximum efficiency to 42 percent, beyond any solar cell available today, which would be a pretty big deal,' said lead author Stefan Wippermann, a postdoctoral researcher at UC Davis. 'In fact, there is reason to believe that if parabolic mirrors are used to focus the sunlight on such a new-paradigm solar cell, its efficiency could reach as high as 70 percent,' Wippermann said. Galli said that nanoparticles have a size of nanometers, typically just a few atoms across. Because of their small size, many of their properties are different from bulk materials. In particular, the probability of generating more than one electron-hole pair is much enhanced, driven by an effect called 'quantum confinement.'"

"U.K. solar electricity may more than double this year as a boom in solar farms and domestic installations adds 2 gigawatts of new capacity, according toTrina (TSL) Solar Ltd., the third-biggest solar cell maker. The U.K. industry benefits from a stability that 'every other country in the world pretty much envies right now,' Ben Hill, president of Trina Solar Europe, said in a Jan. 25 phone interview from the World Economic Forum in Davos, Switzerland. Government incentives for rooftop panels and ground-mounted farms are spurring both types of development, he said....Hill’s prediction for 2 gigawatts of U.K. installations this year compares with the current installed base that Energy Minister Greg Barker put at 1.8 gigawatts in a Jan. 16 speech. London-based Bloomberg New Energy Finance predicts installations this year will total 1.1 gigawatts, up from 830 megawatts in 2012. The government is chasing 20 gigawatts of solar capacity by 2020, and on Dec. 27 added the technology to a list of nine deemed crucial for the nation to meet renewable-energy and carbon-reduction targets. That followed the second wettest year on record, with U.K. rainfall averaging 1,330.7 millimeters (52.4 inches), just 6.6 millimeters short of the record set in 2000, according to the Met Office, the government forecaster. Guaranteed prices for electricity, known as feed-in tariffs, or FITs, are the main spur for rooftop installations, and changes to them were the subject of the legal challenges in 2011. Since then, the government has introduced a system of rolling cuts to ensure predictable reductions as solar costs come down and installations mount."
Trina Predicts U.K. Solar ‘Boom’ to Double Installations

".... researchers announced that they’ve set a new record for flexible copper indium gallium selenide (CIGS) solar cells, a type of solar cell that has the potential for low costs because it can be made quickly with relatively small amounts of material. CIGS cells, if made on a flexible plastic or metal foil, can also be flexible, unlike conventional silicon solar panels, which are heavy and rigid. But CIGS cells aren’t as efficient as conventional silicon ones, making it hard for the technology to compete. Efficiency is the most powerful lever for reducing solar power costs. Improved efficiency reduces the number of solar panels needed for a given installation, saving on the cost of panels and labor. The researchers demonstrated solar cells with an efficiency of 20.4 percent, which is far better than the roughly 13 percent efficiency of flexible CIGS cells used in commercial applications such as solar rooftop shingles. It’s also better than typical silicon solar cells, which are roughly 16 percent efficient (higher cost, premium silicon solar cells can have efficiencies as high as 24 percent)."
Thin Film Solar Gets a Boost from a New Record Efficiency
MIT Technology Review, 22 January 2013

"Here's how to make a powerful solar cell from indium and phosphorus: First, arrange microscopic flecks of gold on a silicon background. Using the gold as seeds, grow precisely arranged wires roughly 1.5 micrometers tall out of chemically tweaked compounds of indium and phosphorus. Keep the nanowires in line by etching them clean with hydrochloric acid and confining their diameter to 180 nanometers. (A nanometer is one billionth of a meter.) Exposed to the sun, a solar cell employing such nanowires can turn nearly 14 percent of the incoming light into electricity—a new record that opens up more possibilities for cheap and effective solar power. According to research published online in Science—and validated at Germany's Fraunhofer Institute for Solar Energy Systems—this novel nanowire configuration delivered nearly as much electricity as more traditional indium phosphide thin-film solar cells even though the nanowires themselves covered only 12 percent of the device's surface. That suggests such nanowire solar cells could prove cheaper—and more powerful—if the process could be industrialized, argues physicist Magnus Borgström of Lund University in Sweden, who led the effort."

"The global solar market will rise 22 percent to 33.4 gigawatts in 2013, with gains in China, the U.S. and India more than offsetting declines in Germany and Italy, Deutsche Bank predicted today in a note to investors. The Chinese market, the second biggest in 2012, will more than double to 10 gigawatts this year from 4 gigawatts last year, Deutsche said. The Indian market will more than triple to 4 gigawatts and the U.S. will rise 29 percent to 4.5 gigawatts, the bank’s analysts, led by Vishal Shah, predicted in the note. Those gains will help offset declines in European markets, led by Germany and Italy, where demand will be cut in half, according to the bank. Those two countries were the biggest and third-largest markets in 2012, it said."

"Renowned innovator and futurist Ray Kurzweil predicts that within 20 years we will have our energy problem licked. It’s solved. We just don’t know it yet. As he told Lauren Fenny of PBS: 'One of my primary theses is that information technologies grow exponentially in capability and power and bandwidth and so on. If you buy an iPhone today, it’s twice as good as two years ago for half that cost. That is happening with solar energy — it is doubling every two years…Every two years we have twice as much solar energy in the world. Today, solar is still more expensive than fossil fuels, and in most situations it still needs subsidies or special circumstances, but the costs are coming down rapidly — we are only a few years away from parity. And then it’s going to keep coming down, and people will be gravitating towards solar, even if they don’t care at all about the environment, because of the economics. So right now it’s at half a percent of the world’s energy. People tend to dismiss technologies when they are half a percent of the solution. But doubling every two years means it’s only eight more doublings before it meets a hundred percent of the world’s energy needs. So that’s 16 years. We will increase our use of electricity during that period, so add another couple of doublings: In 20 years we’ll be meeting all of our energy needs with solar, based on this trend which has already been under way for 20 years.' Of course, there are huge integration and storage issues that will need to be addressed. But his point about solar echoes what has occurred with 'green' technologies such as the Prius. Consumer Reports recently found the Prius to have the lowest cost of ownership of any car. People buy it 'because of the economics.' Similar things are happening with electric vehicles. Motor Trend just named the Tesla Model S it’s car of the year, and competitive in price with other luxury car peers. 'At its core, the Tesla Model S is simply a damned good car you happen to plug in to refuel.' For Motor Trend, the environmental benefits are beside the point.... The next area where solar may make huge gains is integration into the skin of buildings, what is know as Building Integrated Photovoltaics, or BIPV. A recent report from Pike research see BIPV growing from just over 400 MW in 2012 to 2,250 by 2017, with annual value increasing from just over $600 mn to $2.4 bn. 'In the future, BIPV will no longer be confined to spandrel or overhead applications. Rather, the entire building envelope will be able to put it to use, allowing the structure to produce its own power and feed additional power into the grid system.' ...But what about the enormous fleet of existing buildings? How to attack that? Stanford scientists may have just found the answer. In tackling the vexing problem that most solar panels are rigid and thereby limited in their applications, Stanford researchers came up with a technology to create decal-type panels that can be stuck to virtually any surface. Including window panes..."

"It takes outside-the-box thinking to outsmart the solar spectrum and set a world record for solar cell efficiency. The solar spectrum has boundaries and immutable rules. No matter how much solar cell manufacturers want to bend those rules, they can’t. So how can we make a solar cell that has a higher efficiency than the rules allow? That’s the question scientists in the III-V Multijunction Photovoltaics Group at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) faced 15 years ago as they searched for materials they could grow easily that also have the ideal combinations of band gaps for converting photons from the sun into electricity with unprecedented efficiency. A band gap is an energy that characterizes how a semiconductor material absorbs photons, and how efficiently a solar cell made from that material can extract the useful energy from those photons. 'The ideal band gaps for a solar cell are determined by the solar spectrum,' said Daniel Friedman, manager of the NREL III-V Multijunction Photovoltaics Group. 'There’s no way around that.' But this year, Friedman’s team succeeded so spectacularly in bending the rules of the solar spectrum that NREL and its industry partner, Solar Junction, won a coveted R&D 100 award from R&D Magazine for a world-record multijunction solar cell. The three-layered cell, SJ3, converted 43.5% of the energy in sunlight into electrical energy — a rate that has stimulated demand for the cell to be used in concentrator photovoltaic (CPV) arrays for utility-scale energy production. Last month, that record of 43.5% efficiency at 415 suns was eclipsed with a 44% efficiency at 947 suns. Both records were verified by NREL. This is NREL’s third R&D 100 award for advances in ultra-high-efficiency multijunction cells. CPV technology gains efficiency by using low-cost lenses to multiply the sun’s intensity, which scientists refer to as numbers of suns."

"Solar panels that can be integrated right into rooftops and the walls of buildings is a new market that is set to grow dramatically over the next five years, according to a new report from Pike Research, a part of Navigant. The report says that the energy capacity of solar panels that are built into the structures of buildings will grow from 400 MW in 2012 to 2.25 GW in 2017, or a five-fold increase worldwide. The solar industry calls this technology “building-integrated photovoltaics” or BIPV. Some of this new capacity will come from thin film solar panels that will be able to be printed right onto building materials, like shingles, steel roof casing, and windows. A lot of companies have been gunning for this market, and many have been held back by the difficult solar production market in 2012. There are at least 53 companies working on this tech, says Pike."

"Bloomberg reported last week that a number of solar developers in Spain have applied for permits to connect to the country’s electric grid and sell solar power at market prices. Taken together the permit requests total 37,5 gigawatts (GW = 1,000 megawatts). Clearly, not all of these proposed facilities will get built. To put it into context, Spain has about 4.2 GW of installed solar capacity at present (representing almost 10% of the country’s peak power generating capability). If even a fraction of these plants were to be built, it would crush the market and bankrupt the developers. However, if the amount is limited, the first few actors are likely to see a profit. The proposed installations are enormous – the largest eyed for Europe to date, ranging from 150 to 500 MW – with costs coming in as low as $.073 to .079 (.055 to .060 Euros) per kilowatt-hour. These plants compare in size to the 290 MW NRG/First Solar Agua Caliente facility in Arizona, and Exelon‘s 230 MW Antelope Valley project in Southern California, but they are considerably less expensive. This is a far cry from a snapshot of solar in Europe just a half decade ago. At that time, Spain was looking at subsidized prices for solar coming in at 9X traditional fossil plants. These prices surely stimulated the market, resulting in Spain installing more solar than the entire rest of world in the boom days in 2007-2008. However, the Spanish economy and ratepayer paid a significant price – transfers from ratepayers to solar developers totaled $3.3 bn before the program was axed this year. It is that kind of program which fuels conservatives’ anger. But it is also this type of program which sometimes sparks a technological revolution. The rest of the world has Spain to thank for inching so far out into traffic that they lost the hood ornament on the car: the stimulus effect from that program (and that of Germany – which has spent a couple billion Euros for 30,000 MW of solar – and other European countries) helped create a global industry with rapidly falling costs and increasing efficiencies. As a consequence, we are now able to talk seriously about grid parity of solar resources, and sun-drenched Spain has gotten to the point that utility-scale programs can be envisioned without subsidies."

"Fabrication of thin-film solar cells (TFSCs) on substrates other than Si and glass has been challenging because these nonconventional substrates are not suitable for the current TFSC fabrication processes due to poor surface flatness and low tolerance to high temperature and chemical processing. Here, we report a new peel-and-stick process that circumvents these fabrication challenges by peeling off the fully fabricated TFSCs from the original Si wafer and attaching TFSCs to virtually any substrates regardless of materials, flatness and rigidness. With the peel-and-stick process, we integrated hydrogenated amorphous silicon (a-Si:H) TFSCs on paper, plastics, cell phone and building windows while maintaining the original 7.5% efficiency. The new peel-and-stick process enables further reduction of the cost and weight for TFSCs and endows TFSCs with flexibility and attachability for broader application areas. We believe that the peel-and-stick process can be applied to thin film electronics as well."

"There is huge potential in solar power. The sun is a giant ball of burning hydrogen in the sky, and it’s going to be sticking around for at least a few more billion years. For all intents and purposes, it’s a free source of energy. Sadly, humanity hasn’t been very good at harnessing its power directly. Our current methods of capturing the sun’s energy are very inefficient. For example, modern silicon and indium-tin-oxide-based solar cells are approaching the theoretical limit of 33.7% efficiency. Well, a research team at Princeton has used nanotechnology to create a mesh that increases efficiency over organic solar cells nearly three fold. Led by Stephen Chou, the team has made two dramatic improvements: reducing reflectivity, and more effectively capturing the light that isn’t reflected. As you can see by the illustration below by Dimitri Karetnikov, Princeton’s new solar cell is much thinner and less reflective. By utilizing sandwiched plastic and metal with the nanomesh, this so-called 'Plasmonic Cavity with Subwavelength Hole array' or 'PlaCSH' substantially reduces the potential for losing the light itself. In fact, it only reflects about 4% of direct sunlight, leading to a 52% higher efficiency than conventional, organic solar cells. PlaCSH is also capable of capturing a large amount of sunlight even when the sunlight is dispersed on cloudy days, which results in an amazing 81% increase in efficiency under indirect lighting conditions when compared to conventional organic solar cell technology. All told, PlaCSH is up to 175% more efficient than conventional solar cells. As you can see in the image to the right, the difference in reflectivity between conventional and PlaCSH solar cells is really quite dramatic."

"There wasn’t much coverage earlier this month of the Saudi Arabia‘s decision to invest $100 billion in solar power. Instead there was a lot of frothy coverage of an International Energy Agency report suggesting the USA could overtake Saudi Arabia as an oil producer by 2020 if a lot of dubious assumptions panned out. Likewise there wasn’t a lot of interest earlier this year when Warren Buffett, through MidAmerican Holdings, put over $2 billion into one solar project in California. Instead there was a lot of noise and grandstanding when the US government picked the wrong bet and lost a quarter as much in Solyndra. The reality is that solar power has come of age and is now a bankable technology attracting the likes of Buffett and Google and KKR and Blackstone and Walmart and MetLife because it garners double-digit returns on investment. Smart money and the Saudi’s know solar works; why don’t we? Take only the news from King Abdullah City for a moment, where spokespeople say they’re targeting around 41,000 megawatts of solar capacity within two decades. Can you imagine the hype if 41 nuclear power plants were seriously canvassed to be built anywhere in the next 20 years? Did you realize more solar panels were installed in Europe last year than all the gas, coal and wind power installations combined? That’s from the Global Market Outlook to 2016 of the European Photovoltaic Industry Association – a great read full of charts “up and to the right” for a region otherwise beset by doldrums. Germany has had days this year where 50% of the electrons consumed were solar power from its 27,000 megawatts of capacity... One analyst, who wants to remain anonymous expects solar power to be competitive with gas-fired power on the eastern seaboard of China by this time next year. The economics will reach that point when it costs $1 to install a watt of solar power capacity – the current market rate is $1.25/w in China down from over $2/w this time last year... There’s not a lot of coverage of the phenomenon of the technology cost curve that is driving down the price of solar power, even though it’s as American as Apple. Instead there’s still a lot of buzz about the latest oil or gas boom, even though we know busts follow those and are already stalking the shale plays."

"A nanostructured 'sandwich' of metal and plastic may be a way to nearly triple the efficiency of organic solar cells, those cheap and flexible plastic energy devices that could be the future of solar power. The researchers were able to increase the efficiency 175 percent and the technology should increase the efficiency of conventional inorganic solar collectors, such as standard silicon solar panels, but that is another research issue. Any solar solution needs to to overcome two primary challenges that cause solar cells to lose energy; light reflecting from the cell, and the inability to fully capture light that enters the cell. With their new metallic sandwich, the researchers were able to address both problems. The subwavelength plasmonic cavity can dampen reflection and trap light. The new technique allowed the team to create a solar cell that only reflects about 4 percent of light and absorbs as much as 96 percent. It demonstrated 52 percent higher efficiency in converting light to electrical energy than a conventional solar cell.  That is for direct sunlight, but the structure achieves even more efficiency for light that strikes the solar cell at large angles, which occurs on cloudy days or when the cell is not directly facing the sun. By capturing these angled rays, the new structure boosts efficiency by an additional 81 percent, leading to the 175 percent total increase."

Dubbed a 'solar energy funnel', the new concept offers a way of using strain to modify the band gap of a semiconductor so that it responds to light within a range of different wavelengths. However, the funnels have yet to be made and tested in the lab – some researchers suggest using them in practical devices could prove problematic."

"The reality of solar panels is that those on the market today aren’t very efficient – most of the solar cells, which make up an entire panel, convert less than a fifth of the sunlight into electricity. But researchers at MIT said on Monday they have come up with a funnel-like design that will manipulate the incoming electrons to engineer more efficient solar cells. The research, just published in the journal, Nature Photonics, used computer modeling to look at how to stretch the semiconductor molybdenum disulfide to change its physical properties to make use of a broader spectrum of sunlight than what silicon, the most common solar cell material, can manage today. Whether the design will work as well in real life will require further research."

"What if we could use solar energy when the sun has set, or wind energy when the air is calm? Donald Sadoway is working on a way to make that happen. The professor of materials chemistry at MIT is leading an effort to develop a new kind of battery -- a 'liquid metal battery' -- that would enable the economical storage of energy from solar, wind and other sources so that it could be used when homes and businesses need it.... Inspired by the technique developed in the 19th century to produce aluminum at very low cost, Sadoway came up with the idea of using such commonly available materials as magnesium and antimony to create the battery. He said a battery of this type housed in a 40-foot shipping container could store enough power to meet the daily needs of 200 American households. Sadoway got enthusiastic applause when he told the audience at TED: 'If we're going to get this country out of its current energy situation, we can't just conserve our way out; we can't just drill our way out; we can't bomb our way out. We're going to do it the old-fashioned American way, we're going to invent our way out, working together."

Figures collated by the EST showed that the annual net benefit from solar PV panels has risen to £635 from around £540 per year. The average size of solar PV installed has increased, said the EST, meaning households generated more electricity and consequently more savings and feed-in tariff income.   However, of the third of Brits approached with solar panels last year only 4 per cent chose to purchase them."

CIRO Group executive Ruben Perez said Friday that the project will help save 236 million barrels of petroleum a year and reduce greenhouse emissions by 217 billion pounds. Puerto Rico's government also expects construction to start soon on what will be the region's largest wind farm. It will be near the island's southern coast."

"Scientists at California's Stanford University have managed to construct the first solar cell made entirely of carbon. If ultimately brought to market, a carbon-based solar cell could offer a potential alternative to the expensive materials currently used in photovoltaic devices. 'Unlike rigid silicon solar panels that adorn many rooftops, [our] thin film prototype is made of carbon materials that can be coated from solution,' she explained. 'Perhaps in the future we can look at alternative markets where flexible carbon solar cells are coated on the surface of buildings, on windows or on cars to generate electricity.' As expected, the coating technique also has the potential to reduce manufacturing costs. 'Processing silicon-based solar cells requires a lot of steps,' Stanford graduate student Michael Vosgueritchian confirmed. 'But our entire device can be built using simple coating methods that don't require expensive tools and machines.'"

"The Saudis are raising $100 billion for solar-power development, which could ease its rapidly growing demand for electric power. Though natural gas would be cheaper, the Saudis may prefer solar. Prince Turki bin Faisal Al Saud, an important member of the Saudi royal family, announced last week that his hope was that Saudi Arabia would replace 100 percent of its power generation with renewables within his lifetime. This follows public announcements earlier in the year that the kingdom was in the process of raising $109 billion in investments for solar power and was already in the process of constructing 100 megawatts of solar generation in Mecca as part of a larger renewable energy plan for the city. It's important to note that the energy proclamation by Prince Turki (a classmate of Bill Clinton's at Georgetown) needs to be taken in context. He has never held an energy related position in the Saudi government, but has held very high-profile government roles, including director of intelligence and ambassador to the United States. The 100 percent claim is clearly aspirational, but the $100 billion investment, representing enough solar to meet roughly one-third of current Saudi power demand, appears to be entirely serious. Saudi Arabia's interest in renewables, and solar in particular, highlights a handful of important points: * Power demand growth in the Middle East * Saudi Arabia is bullish on future oil prices  * Saudi's limited access to natural gas * Oversupplied solar market may have a new demand base."

"China is creating supportive measures to shore up its ailing photovoltaic (PV) industry, which has been rocked by recent U.S. duties on Chinese exports over alleged dumping. In the latest attempt, State Grid Corporation of China (SGCC), the country's largest state-owned utility company, announced a plan to allow small-scale distributed solar power generators to connect to its power lines. Under the plan, SGCC will allow solar power generators with less than 6 megawatts of installed capacity to be connected to the grid."

"Clean energy has become a dirty word in presidential politics. In their second debate, Mitt Romney and Barack Obama each tried to outdo the other’s love of fossil fuels: Obama extolling his record on oil and natural gas production, Romney vowing to take 'advantage of the oil and coal we have here.' The Republican candidate has ridiculed the administration’s $535 million loan guarantee to Solyndra, the bankrupt California-based solar panel maker, and accused Obama of living 'in an imaginary world where government-subsidized windmills and solar panels could power the economy.' The candidates’ coolness to renewable energy comes at a time when the domestic supply of traditional energy sources, such as oil and natural gas, is at an all-time high. And yet this failure to make the promise of renewables a keynote in the debate is a huge missed opportunity. In particular, it ignores the dramatic reduction in the cost of photovoltaic solar power worldwide and the considerable benefits to U.S. consumers and the environment. The untold story of this campaign is that what killed Solyndra may turn out to be a boon for the nation. 'Economically and technologically, the game is over,' says Bill Powers, a San Diego engineer and board member of Solar Done Right, a group that proselytizes for rooftop solar power. 'The hangups in the U.S. are strictly political.' Over the past five years the price of photovoltaic panels has plummeted 75 percent, due largely to a glut of Chinese-made panels. The fall in prices rendered technically advanced photovoltaic panels, like those produced by Solyndra and other U.S. companies, too expensive to compete. But cheap panels have been a godsend for consumers... Nationally, the average cost of residential installations—including hardware, permits, and labor—has plummeted from $9 a watt in 2006 to $5.46. Averaging in commercial industrial installations, the national installed price plummets to $3.45 a watt, says the Solar Energy Industries Association, a Washington-based trade group. The result is a burgeoning rooftop revolution. The SEIA says almost 52,000 residential rooftop systems were installed in the U.S. last year, up 30 percent from a year earlier. Total rooftop installations, including on commercial buildings, grew 109 percent from 2010 to 2011, according to SEIA data. Total photovoltaic installations are projected to grow an additional 71 percent this year from 2011 levels. Worldwide, the picture is even more positive. Australia projects that 10 percent of its 8 million houses will have rooftop systems within the next 12 months—most of that growth coming in the past three years. European rooftop installations continue to outpace those in the U.S., even as some countries begin to pare subsidies that have helped spur a continental rooftop boom. Including residential, commercial, and industrial-scale projects, the world had installed about 67 gigawatts of photovoltaic power at the end of last year—up from just 1.5 gigawatts in 2000. Despite such breakthroughs, the U.S. economy is harnessing only a fraction of solar’s potential benefits. Based on U.S. Census Bureau data, about 100 million U.S. residential units could physically hold rooftop systems one day, generating by one estimate 3.75 trillion kilowatt hours of electricity a year. In 2011, total U.S. electrical generation from all sources was about 4 trillion kilowatt hours—42 percent of that from coal, according to the U.S. Energy Information Administration. The trouble is, many of the big,investor-owned utilities that provide about 85 percent of America’s electricity see solar as both a technical challenge and a long-term threat to their 100-year-old profit models. And the lack of a national energy policy means regulation of solar is up to states, public service commissions, and a wealth of local governments and bureaucracies—many of whom have a vested interest in maintaining the status quo."

"The United States finally has a road map for developing solar energy on federal land in the West. The big idea: Seventeen solar-energy zones – about 285,000 acres of public lands in six western states – have been set aside as priority areas for commercial-scale solar development. That way, instead of approving such large renewable energy projects on a case-by-case basis where developers want to build them, the energy zones will guide development to areas that are high in solar energy, close to transmission lines, and have, in the Interior Department's words, 'relatively low conflict with biological, cultural, and historic resources.' The road map also excludes 79 million acres of federal land as being inappropriate for development and another 19 million acres as "variance" areas where the government would continue to decide solar projects case by case. Secretary of the Interior Ken Salazar finalized the roadmap at a signing Friday. The six states are Arizona, California, Colorado, Nevada, New Mexico, and Utah."

"Alternative Energy Development Board (AEDB) Managing Director Arif Alauddin has said prices of solar panels have dropped 80% over the last five years, making alternative energy attractive for the consumers. 'We should avail of the opportunity and switch to solar energy to overcome the energy crisis,' he stressed while speaking at the International Exhibition and Conference on Alternative Energy and Energy Efficiency, organised by the Renewable and Alternative Energy Association of Pakistan here on Saturday. As the country was generating power at an average rate of Rs20 per unit, Alauddin said the consumers could have cheaper electricity with the help of solar applications. Despite the decrease in the cost of battery, the solar panels were still expensive, but the consumers could take benefit of them in day time, he suggested."

"Silicon nanowire and nanopore arrays promise to reduce manufacturing costs and increase the power conversion efficiency of photovoltaic devices. So far, however, photovoltaic cells based on nanostructured silicon exhibit lower power conversion efficiencies than conventional cells due to the enhanced photocarrier recombination associated with the nanostructures. Here, we identify and separately measure surface recombination and Auger recombination in wafer-based nanostructured silicon solar cells. By identifying the regimes of junction doping concentration in which each mechanism dominates, we were able to design and fabricate an independently confirmed 18.2%-efficient nanostructured ‘black-silicon’ cell that does not need the antireflection coating layer(s) normally required to reach a comparable performance level."

"V3Solar has developed a new way to convert the sun's energy into electricity using traditional technology in a new way, and in so doing have discovered a way to get twenty times more electricity out of the same amount of solar cells. Their new device, called the Spin Cell, does away with the traditional flat panel and instead places the solar cells on a cone shaped frame which are then covered with energy concentrators. Once in operation, the whole works spins, making unnecessary the need for tracking hardware and software.... Because of the great potential of solar energy, researchers have looked into increasing the efficiency of solar cells by using lenses or mirrors to direct more of the sun's energy onto them hoping to get more electricity out of the same number of cells. Unfortunately, doing so tends to create so much heat that the cells become useless. The engineers at V3Solar took this idea and modified it to prevent such overheating by mounting the cells on a rotating platform; doing so means that each cell only receives extra heat for a very short amount of time and is then allowed to cool as the cone spins. The concentrators form an outer skin creating a hermetically sealed inner environment for the triangular shaped blue colored solar cells. The cone is situated on a base of electromagnets powered by some of the energy that has been converted from the sun's energy by the solar cells, creating a nearly frictionless spin. The result is a marvel of engineering and an artistic triumph – a means to produce much more electricity than traditional flat panels in a pleasing, and as the company says, beautiful way."

"Reports of the demise of the European solar industry have been greatly exaggerated. That is the central conclusion of a new status report from the European Commission's Joint Research Centre, which reveals that despite subsidy cuts in a host of key markets two-thirds of the world's new solar PV panels were installed in Europe last year. It also confirms that solar power delivered two per cent of the EU's electricity needs in 2011, equivalent to the national electricity demand of Austria. Writing in the foreword of the report, Arnulf Jager-Waldau, senior scientist for renewable energy at the Joint Research Centre, said that demand for solar power was being driven by a drastic reduction in the cost of solar panels. 'From 2008 to second quarter of 2012, residential PV electricity system prices have decreased by almost 60 per cent in the most competitive markets, and in some markets, the cost of PV-generated electricity is already cheaper than residential electricity retail prices,' he wrote. 'Due to falling PV system prices and increasing electricity prices, the number of such markets is steadily increasing.' He added that as a result solar energy had attracted almost half of all new renewable energy investment globally last year, approaching $130bn, with around two-thirds invested in Europe. 'In 2011, the photovoltaic industry production increased by almost 40 per cent and reached a world-wide production volume of about 35 GWp of photovoltaic modules,' he wrote. 'Yearly growth rates over the last decade were on average between 40 per cent and 90 per cent, which makes photovoltaics one of the fastest growing industries at present.' The report acknowledged that European solar firms are facing growing competition from Chinese manufacturers – a scenario that has prompted threats of legal action against China by European and US firms."

"First Solar Inc. (FSLR) Chief Executive Officer Jim Hughes is stepping up efforts to manage power plants that generate electricity from the sun, helping utilities use the technology in a way his rivals in China can’t. The biggest U.S. solar panel maker plans to build new projects from the Middle East to Australia and use proprietary systems that help power-purchasers manage the amount they buy from solar farms, Hughes said in his first interview since taking the CEO position in May. The company’s pitch to utilities is that it will help them predict uneven power flows from solar panels, giving grid operators the ability to integrate the facilities into their networks alongside those that burn fossil fuels. That’s making First Solar less dependent on manufacturing, an industry dominated by Chinese companies led by Suntech Power Holdings Co. (STP)."

"The solar-power business is expanding quickly in the U.S., helping lift the cloud that has surrounded the industry since the demise of Solyndra LLC a year ago. But the growth isn't coming from U.S. solar-panel manufacturing, despite the money and rhetoric devoted to the industry by the Obama administration. Instead, it is in installations of largely foreign-made panels, whose falling price has made solar more competitive with other forms of power. 'There should be little emphasis put on where the panels are made,' said Lyndon Rive, chief executive of SolarCity Corp., which finances and installs rooftop solar systems."

"China's push into solar energy was supposed to be a proud example of how the country was advancing into hi-tech manufacturing. But now the whole sector is on the brink of bankruptcy. Two years ago, LDK Solar, one of China's largest solar panel makers, built a new, state-of-the-art factory in the central city of Hefei. It sits in one of the city's industrial parks, a big LDK Solar logo on its wall, with the New York-listed company's slogan underneath: 'Lighting the Future'. 'It cost 2.5 billion yuan (£250m) to build, the majority of the equipment was imported from Germany, and it hired 5,000 staff,' said Jie Xiaoming, a 30-year-old who works at the plant's quality control and packaging department.  Last month, however, 4,500 of the staff were put on gardening leave. They receive 700 yuan a month to stay at home. The factory has shut down 24 of its 32 production lines. 'There do not seem to be any orders. People are still turning up for work, but mostly just sleeping. The management has not said much, just that the United States has a new policy that is stopping our exports,' said Mr Jie. .... in Europe and the US, governments provided subsidies to buy Chinese-made panels as part of commitments to boost renewable energy. But the incentives created a glut of suppliers, and since 2010, the price of polysilicon wafers has fallen by nearly three-quarters. The price is now below the production cost - in the latest quarter, LDK Solar's gross margin was -65.5pc. Meanwhile, the debt crisis in Europe has cut government subsidies to the sector and the US imposed a 31pc tariff in May on Chinese wafers, complaining that manufacturers were being underwritten by the government. In July a group of 25 European solar companies followed suit, filing an anti-dumping complaint with the European Union. At the same time, the quality of the solar equipment being made by Chinese companies, even by the biggest companies, is often not export-grade. While the Chinese government has promised to hugely increase its purchases of solar panels, there is a significant excess capacity in the domestic market that has kept prices low. China's big five firms are all reporting disastrous trading and heavily indebted balance sheets."

"Princeton Satellite Systems announced on Friday an electric car charging station integrated with a stationary solar power system. The company claims the SunStation is the first 100% green charging station for electric vehicles, because all power comes from the Sun. The SunStation has a built-in battery pack that enables recharging electric cars 24 hours a day, even when the Sun has set. It provides a 240 volt charging voltage for charging an electric car at it's normal rate, namely the Nissan Leaf in 8 hours, a Chevy Volt in 4 and a Toyota Prius Plugin Hybrid in 1.5. The system is installed simply by pouring a concrete base and bolting the station to the base. The SunStation does not require a wired connection to the electricity grid, because of the battery pack. Other electric vehicle charging stations require an electricity grid connection to provide the power. It does wirelessly connect via the cell phone network for a payment system, and allowing Princeton Satellite Systems to remotely manage the station."

"New research out of Berkeley Lab and the University of California suggests that it is possible to make solar cells from any semiconductor, opening the door to solar panels made from cheaper, more abundant materials. Until now, phosphides and sulfides of metals have been judged ill-suited for solar cells because of the near-impossibility of chemically doping them with the quality of p-n junctions required. The new approach, dubbed 'screening-engineered field-effect photovoltaics' (SFPV), sidesteps the problem by inducing p-n junctions in semiconductors by applying an electric field."

"Researchers from UCLA have developed a new transparent solar cell that is a significant step towards giving the windows in homes and other buildings the ability to generate electricity while still being transparent. The research team 'describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye.' They created the device from a photoactive plastic that generates an electrical current from infrared light. 'These results open the potential for visibly transparent polymer solar cells as add-on components of portable electronics, smart windows and building-integrated photovoltaics and in other applications,' said study leader Yang Yang, a UCLA professor of materials science and engineering, who also is director of the Nano Renewable Energy Center at California NanoSystems Institute (CNSI). Yang also said that there has been a definite world-wide interest in polymer solar cells. 'Our new PSCs are made from plastic-like materials and are lightweight and flexible,' he said. 'More importantly, they can be produced in high volume at low cost.'... The new study appears in the journal ACS Nano.”
Solar Cells for Windows Take Another Step Forward
CleanTechnica, 22 July 2012

"Researchers from the Karlsruhe Institute of Technology (KIT) have launched a four-year research program that aims to improve the efficiency of organic solar cells to more than 10 percent. Organic solar cells are cheaper to produce, lighter and more flexible than traditional silicon-based solar cells, opening new perspectives in particular for the architectural design of buildings. Solar modules can be integrated in facades and even windows. The downside is that the efficiency rate of OPV cells remains much lower than inorganic solar cells, demonstrating 15-20 percent efficient. Led by Dr. Alexander Colsmann, at KIT's Light Technology Institute, the newly-launched project uses tandem architectures. Two solar cells with complementary absorption characteristics are stacked directly on top of each other to achieve better sunlight harvesting and more efficient energy conversion. The KIT scientists said they use novel materials, develop innovative device architectures, optimize their stability, and test the solar cells in a real-life environment. They also intend to transfer manufacturing processes from the laboratory to an industry-compatible production environment so as to promote future commercial use of their results. ... Recently, Heliatek GmbH (Dresden, Germany) claimed it had pushed the record efficiency for organic solar cells higher, achieving an efficiency of 10.7 percent in a 1.1 square centimeter tandem cell. Measurements, led by independent test house SGS SA (Geneva Switzerland), showed that the cell improved efficiency under low light conditions and that the efficiency remains constant with temperature."

"Riding on the crash in photo voltaic (PV) panel prices, the solar power sector in India had a dream run last year with capacity ballooning to 940MW in 2011-12 from a paltry 20MW in 2010-11. That's just statistics. What's significant and not borne out by these statistics is the fact that the cost of power from solar is now on a par with the cost of power from new coal-based plants. In industry parlance, it's referred to as grid parity, considered the holy grail of solar power. Grid-parity is the point where the cost of electricity generated from sunshine becomes competitive with that of power produced from coal, gas, wind and hydro-based plants. .... 'If we compare the cost of power from new coal-based plants, it will be at par with that of solar. If one takes into account the total duration of the power purchasing agreement, which is 25 years, grid-parity is already there. Solar power needs only a one-time investment in the form of land and PV panels. Its fuel, which is sunshine, is free unlike coal where price will head only northwards,' said Gaurav Sood, managing director, Solairedirect, a solar power producer. ... Three years ago, the cost of generating a unit of solar energy was around Rs 18. In fact, solar has already taken over diesel as a cheaper form of energy and a lot of telecom towers are now being run on solar power. In recent years, there has been a sharp decline in capital costs for solar PV plants. PV module prices have fallen a sharp 80% in the last five years and 30% during last year alone."

"Global investment in renewable energy reached a record $257 billion last year, with solar attracting more than half the total, according to a U.N. report released Monday. Investment in solar energy surged to $147 billion in 2011, a year-on-year increase of 52% thanks to strong demand for rooftop photovoltaic installations in Germany, Italy, China and Britain. China was responsible for almost a fifth of the total investment volume, spending $52 billion on renewable energy last year. The United States was close behind with investments of $51 billion, as developers sought to benefit from government incentive programs before they expired. Germany, Italy and India rounded out the top five. Large-scale solar thermal installations in Spain and the United States also contributed to growth during a fiercely competitive year for the solar industry. Several large American and German manufacturers fell victim to price pressure from Chinese rivals that helped to halve the cost of photovoltaic modules in 2011.   The report's authors said the demise of companies such as Solyndra, Evergreen Solar, SpectraWatt, Solar Millenium and Solon was a sign that the solar industry is maturing. 'In 1903, the United States had over 500 car companies, most of which quickly fell by the wayside even as the automobile sector grew into an industrial juggernaut,' the report said. 'Today, the renewable energy sector is experiencing similar growing pains as the sector consolidates.' Wind power investment slipped 12% to $84 billion due to uncertainty about energy policy in Europe and fewer new installations in China, according to the report. Overall investment in renewable energy grew 17%, a slowdown from the 37% increase in 2010. Still, the head of the U.N. Environment Program claimed the latest figures are an indication that renewable energy is drawing level with fossil fuels in some markets. 'These trends are real, they are substantive and they are transformative,' Achim Steiner told reporters in a conference call."

"One of the biggest challenges facing the silicon photovoltaic industry is making solar cells that are economically viable. To meet this goal, the module cost, which is currently about $1/watt, needs to be decreased to just half that. Much of this cost comes from the silicon material and the expensive fabrication processes often used. In a new study, a team of scientists and engineers has demonstrated that a hybrid solar cell covered in silicon nanocones and a conductive organic polymer can address both cost-cutting areas while providing excellent performance. The researchers, led by Professor Yi Cui and Professor Michael D. McGehee from Stanford University, have published their study in a recent issue of .....  After testing the solar cell and making some improvements, the researchers produced a device with an efficiency of 11.1%, which is the highest among hybrid silicon/organic solar cells to date. In addition, the short-circuit current density, which indicates the largest current that the solar cell can generate, is only slightly lower than the world record for a monocrystalline silicon solar cell, and very close to the theoretical limit. Due to the hybrid silicon nanocone-polymer solar cells’ good performance and inexpensive processing, the researchers predict that they could one day be used as economically viable photovoltaic devices."

"German solar power plants produced a world record 22 gigawatts of electricity per hour - equal to 20 nuclear power stations at full capacity - through the midday hours on Friday and Saturday, the head of a renewable energy think tank said. The German government decided to abandon nuclear power after the Fukushima nuclear disaster last year, closing eight plants immediately and shutting down the remaining nine by 2022. They will be replaced by renewable energy sources such as wind, solar and bio-mass. Norbert Allnoch, director of the Institute of the Renewable Energy Industry (IWR) in Muenster, said the 22 gigawatts of solar power per hour fed into the national grid on Saturday met nearly 50 percent of the nation's midday electricity needs. 'Never before anywhere has a country produced as much photovoltaic electricity,' Allnoch told Reuters. 'Germany came close to the 20 gigawatt (GW) mark a few times in recent weeks. But this was the first time we made it over.'...The record-breaking amount of solar power shows one of the world's leading industrial nations was able to meet a third of its electricity needs on a work day, Friday, and nearly half on Saturday when factories and offices were closed....Government-mandated support for renewables has helped Germany became a world leader in renewable energy and the country gets about 20 percent of its overall annual electricity from those sources. Germany has nearly as much installed solar power generation capacity as the rest of the world combined and gets about four percent of its overall annual electricity needs from the sun alone."

"An experimental solar-powered airplane took off from Switzerland on its first transcontinental flight Thursday, aiming to reach North Africa next week. Pilot Andre Borschberg planned to take the jumbo jet-size Solar Impulse plane on its first leg to Madrid, Spain, by Friday. His colleague Bertrand Piccard will take the helm of the aircraft for the second stretch of its 2,500-kilometer (1,554-mile) journey to the Moroccan capital Rabat. Fog on the runaway at its home base in Payerne, Switzerland, delayed the take off by two hours, demonstrating how susceptible the prototype single-seater aircraft is to adverse weather. 'We can't fly into clouds because it was not designed for that,' Borschberg said as he piloted the lumbering plane with its 63-meter (207-foot) wingspan toward the eastern French city of Lyon at a cruising speed of just 70 kilometers an hour (43.5 mph). Before landing in Madrid in the early hours of Friday, Borschberg will face other challenges, including having to overfly the Pyrenees mountains that separate France and Spain. Just in case things go disastrously wrong, Borschberg has a parachute inside his tiny cabin that he hopes never to use. 'When you take an umbrella it never rains,' he joked in a satellite call with The Associated Press."

The state Public Utilities Commission on Thursday tweaked its rules to authorize an increase in the number of residential, commercial and government buildings that can participate in a program that allows solar users to lower their electricity bills by getting credit for excess power sent back to the grid. The move raises the maximum total capacity of all the state's rooftop solar systems to about 5,200 megawatts from a current 2,400 megawatts. That's enough new electricity to power about 2.1 million homes."

"Saudi Arabia, the world's top oil exporter, may finally be getting serious about overcoming the technical and financial hurdles for tapping its other main resource: sunshine. Thousands of solar power panels have sprung up across Europe over the past few years, thanks to generous subsidies that make the technology an attractive alternative to conventional energy. Saudi Arabia too, wants to generate much more solar power as it lacks coal or enough natural gas output to meet rapidly rising power demand. Doing so would allow it to slash the volume of oil it burns in power plants bankrolled by billions of dollars worth of saved oil earnings. 'At world market prices, solar is competitive if you use crude oil to generate electricity,' said Maher al-Odan, a senior consultant at King Abdullah City for Atomic and Renewable Research (KA-CARE) which was set up to plan Saudi Arabia's energy mix. Saudi Arabia has said it wants to become a major solar producer before, but its investments amount to much less than 50 megawatts versus several countries which have added thousands of megawatts a year. This month, KA-CARE set forth a much more ambitious plan, recommending that the kingdom aim to get more than a third of its peak-load power supply, or about 41 gigawatts (GW), from the sun within two decades at an estimated cost well over $100 billion. Making the plan work economically rests on three assumptions: that technology improvements will cut costs, that a domestic solar industry will emerge and create jobs for a booming population, and that many billions of dollars worth of exportable oil will be saved. An average of 700,000 barrels a day of crude were used in Saudi power stations during the peak air-conditioning demand period from May to September last year, according to official data supplied to the Joint Organisations Data Initiative (JODI)."

"An Israeli solar company says it has raised more than $200 million to build eight solar energy fields in the country's southern desert. Arava Power Co. says the deal is by far the biggest ever in Israel's solar power industry. Arava Power's chief executive, Jon Cohen, said Tuesday the installations, to be built in southern Israel's Negev desert, are 'another step toward energy independence for Israel and a greener future for generations to come.' The company says the fields will generate 58.5 megawatts of power. Investors include the Noy investment fund, French energy company EDF, Bank Hapoalim, Israeli insurer Migdal and pension fund manager Amitim. Israel hopes to generate 10 percent of its power from renewable sources by 2020."

"Electric cars are far more expensive to buy than their petrol equivalents, largely because the cost of the lithium-ion battery that powers the vehicle is so high – currently about $12,000. But the fuel costs of electric vehicles are already far lower than for petrol-powered ones. In the US, for example, the petrol for an average car costs about 8 cents per kilometre, compared with less than 2 cents for the electricity to power an electric car. In Europe, where fuel tax is higher, the numbers are 12.5 cents and 2.5 cents, respectively. Either way, that is a huge gap. So for electric vehicles to compete on price, battery costs need only fall far enough to be swallowed by that gap, and Galves believes that it is likely to happen sooner than most people think. First, he expects the costs of batteries to plummet as mass production ramps up – just as they did for laptops – to less than $7000 by 2015. Second, the gap is likely to widen with most analysts expecting oil prices to keep rising. 'On a 10-to-15-year view, it’s almost impossible for electrification not to carve out a decent portion of the market,' says Galves, who expects electric vehicles to be economic within a decade even without the subsidies that many governments currently give.  The effect of falling electric vehicle costs will be reinforced by strengthening fuel efficiency and emissions policies in the world’s most important car markets. The policies of the world’s biggest gas guzzler will soon be among the toughest. In 1975, US president Jimmy Carter passed a law forcing vehicle manufacturers in the US to meet average fuel efficiency standards. For cars, that number has languished at around 27 miles per gallon (11.5 kilometres per litre) since the early 1990s, but recent legislation means average fuel economy must double to 54.5 mpg by 2025. The standard has been rising since 1978, and by 2020 the targets become so demanding, says Galves, that car manufacturers will not be able to meet them without selling a significant number of electric vehicles. Galves expects them to make up a fifth of US car sales in 2020. The impact will be dramatic. Every day, US vehicles guzzle about 9 million barrels of oil – the biggest single element in our daily global consumption of almost 90 million barrels (see chart, top left). Deutsche Bank oil analysts expect US petrol consumption to plummet, almost halving by 2030. The story is the same in the European Union, which regulates carbon dioxide emissions per kilometre rather than miles per gallon. Cars manufactured there in 2020 must reduce their average emissions by more than a quarter compared with models made in 2015. Such standards will especially encourage electrification because they govern 'tailpipe' emissions pumped out in the day-to-day running of car engines and not those emitted while they are being built. By this measure, electric vehicles are zero emission. Deutsche Bank expects them to make up 25 per cent of Europe’s car sales in 2020, accelerating the decline in demand for petrol. So much for the world’s richer nations. In China, where the developing car market is booming, the demand for petrol will continue to rise for at least a decade. Yet the global impact will be limited because the size of China’s car fleet is currently just a fifth of that of the US. The Chinese government too is strongly committed to electric vehicles as one way of tackling appalling air quality in the cities and the country’s dependence on imported oil. Deutsche Bank forecasts that Chinese petrol demand will start to fall from 2025, as electric vehicles become more common. The net effect is that global petrol demand will peak as early as 2015. 'From that point forward,' writes Deutsche Bank’s lead oil analyst Paul Sankey in a research note. 'We believe gasoline demand will be on an inexorable and accelerating decline.' And as a result, he argues, global demand for crude oil will go the same way in about 2020. Others disagree with Deutsche Bank’s analysis. The International Energy Agency has long been dismissive about predictions of an early peak in the global oil supply. It is just as dismissive that demand will decline within the next couple of decades. It forecasts that daily oil demand will rise to 107 million barrels by 2035 on the basis of current government policies. Fatih Birol, the agency’s chief economist, believes that there are simply too many cars in the world – about a billion and rising – for electric vehicles to have a meaningful impact in the short term. Although most governments have policies to encourage electrification, they are very unlikely to achieve their targets. Even if they do, says Birol, the number of electric vehicles on the road in 2020 will be just 20 million – about 2 per cent of the total fleet. Stefanie Lang, a London-based automobile analyst at investment-research firm Sanford C. Bernstein, agrees that electric vehicles will make only limited progress over the next 10 to 15 years. She argues that they will struggle because they will remain far too expensive and will face fierce competition from the incumbent technology – the internal combustion engine. Even after a century of development, the internal combustion engine has the capacity to make major improvements in fuel economy, says Lang, rattling off three examples. .... So what does the motor industry itself think lies ahead? That the internal combustion engine’s days are numbered, for one thing. In a recent survey, consultants KPMG asked 200 top executives of car companies how long they thought the traditional engine would continue to prevail over electric vehicles. Some 70 per cent answered 1 to 10 years, but only 18 per cent thought 10 to 20 years. One reason for the result could be that electrification is now widely seen as the best way to make major reductions in transport emissions, even taking into account the emissions from generating the electricity in the first place. That is because electric vehicles are far more efficient than petrol cars. Take the Nissan Leaf. It is responsible for just 99 grams of CO2 per kilometre, even when charged on electricity generated by the average mix of coal, natural gas, nuclear and renewables. That makes it 40 per cent cleaner than a typical petrol car in Europe. And as electricity generation becomes cleaner, the emissions of electric vehicles will fall further still – unlike those of cars powered by biofuel or natural gas (see New Scientist, 25 February, p 48)."

"The world's solar power generating capacity will grow by between 200 and 400 percent over the next five years, with Asia and other emerging markets overtaking leadership from Europe, a European industry association said on Monday. 'Europe has dominated the global PV (photovoltaic) market for years but the rest of the world clearly has the biggest potential for growth,' the European Photovoltaic Industry Association (EPIA) said in its market outlook until 2016. The fastest PV capacity growth is expected in China and India, followed by the southeast Asia, Latin America, the Middle East and North Africa in the next five years, said the report distributed at a PV conference in northern Italy. Global installed PV capacity, which turns sunlight into power, is expected to have risen to between 207.9 gigawatts and 342.8 GW in 2016, depending on the level of political support, from 69.7 GW in 2011, the report said. This year, the world's total PV capacity is expected to rise to between 90 and 110 GW, EPIA's Secretary General Reinhold Buttgereit told the conference."

"German solar installations may have more than tripled in the first quarter from a year ago, the country’s deputy environment minister said. 'The first quarter had big installations,” Katherina Reiche said today in an interview during an informal meeting of ministers in Denmark. 'It is assumed that nearly 1,800 megawatts were installed.' Germany added 513 megawatts in the same period last year, according to the Bundesnetzagentur grid regulator."

"Thin-film solar panels may perform better in hot climates than rival crystalline products, based on half a year of data from the first Indian projects, an executive at the nation’s largest contractor on the developments said. 'The last six months for which we have data show that the performance of crystalline in hot climates is not as efficient as thin film,' said S.N. Subrahmanyan, senior executive vice president of construction at Larsen & Toubro Ltd. (LT) 'Of course, it’s still early days. But that’s what we’re seeing.' Concerns over use of thin-film panels were raised as First Solar Inc. (FSLR), the largest supplier, in February boosted provisions for warranties by $37.8 million due to potential for 'increased failure rates in hot climates.' Developers and their lenders are seeking data on how technologies fare in warmer conditions as Europe, the biggest solar market, cuts renewables subsidies. Traditional crystalline modules are silicon-based, while thin-film technology coats panels with materials such as cadmium telluride, copper indium gallium selenide and amorphous silicon. Crystalline’s competitiveness matches thin-film when placed on trackers to rotate panels with the sun’s movement, boosting output as much as 20 percent, Subrahmanyan said in an interview."

"The average price of an electric vehicle-grade battery fell 14 percent year-on-year to $689 per kilowatt hour in the first quarter as manufacturing capacity outstripped demand, a report by Bloomberg New Energy Finance said on Tuesday.Lower battery costs for electric vehicles could improve their commercial uptake, which has been slow. The United States wants to see up to 1 million electric and plug-in hybrids on its roads by the middle of next decade. To help achieve this goal, the U.S. government has spent over $2 billion under President Obama to underwrite domestic battery production and billions more to finance electric car development to cut U.S. oil imports and reduce pollution. But electric vehicles such as Mitsubishi Motor Corp.'s iMiEV, Nissan Leaf or Tesla Model S to travel longer distances need to store 16 to 85 kWh at a cost of $11,200 to $34,000, which is around 25 percent of the total cost of the vehicle. A Tesla car with an 85 kWh battery, for example, has a range of about 300 miles before it needs to recharge. Battery prices for plug-in hybrid vehicles such as GM's Volt are on average 67 percent higher than those for electric-only vehicles, mainly due to the greater power-to-energy performance required for plug-in hybrid vehicles."

"California may be the solar Promised Land but Delaware is where those big green dreams go to die. On Monday, Solar Trust of America became the latest solar developer to file for bankruptcy in Delaware federal court, putting into jeopardy photovoltaic power plant projects utilities were counting on to generate 2,000 megawatts of electricity – enough to light hundreds of thousands of homes at peak output. Among the projects was what would have been the world’s largest solar station, the Blythe Solar Power Project, a 1,000-megawatt power plant to be built in the Mojave Desert that had received a $2.1 billion federal loan guarantee offer. Solar Trust’s parent company, German developer Solar Millennium, filed for bankruptcy in Germany in December and moved to sell its U.S pipeline of projects to a German photovoltaic power plant developer called Solarhybrid. Then late last month Solarhybrid itself sought bankruptcy protection, citing a cutback in German subsidies for solar energy. According Solar Trust’s bankruptcy filings, the company has liabilities of $20 million and missed a $1 million rent payment on April 1 to the U.S. Bureau of Land Management for the 7,025-acre Blythe site. Solar Trust this week faces deadlines to pay $30.9 million in security deposits to related to its right to connect its projects to the power grid."

"In a move with potential to spark a trade war, the Commerce Department ruled Tuesday that US solar panel manufacturers are being victimized by Chinese manufacturers dumping cheap panels in North America that were unfairly subsidized by the Chinese government. Amid an ongoing investigation, Commerce determined that Chinese producers and exporters have received subsidies ranging from 2.90 percent to 4.73 percent, a smaller advantage over US manufacturers than many analysts had expected. Commerce will now direct tariffs to be collected on Chinese imports. The Obama administration argues that dumping of under-priced solar panels is a violation of World Trade Organization rules that has come at a high cost to US panel manufacturers. Several have already been forced to close domestic manufacturing facilities even though 2011 was one of the best years ever for US solar panel sales. While the US remains a leader in the production of thin film – an advanced type of solar-electric panel technology – at least 12 US manufacturers that made more conventional photovoltaic panels have laid off employees, shut down plants or filed for bankruptcy during the past two years, according to the Coalition for American Solar Manufacturing. The group of seven US manufacturers filed trade petitions last year against two Chinese silicon solar PV manufacturers, leading to the Commerce investigation."

"..... analyst firm Bloomberg New Energy Finance (BNEF) is now predicting that substantial penetration of energy storage technologies into national grids is likely to be led by an expected drop in battery prices over the next few years. According to a new report from the firm, grid-scale lithium-ion battery projects today cost more than $1,000/kWh, but with battery manufacturing capacity likely to outstrip supply in the short term, BNEF forecast prices will drop over the next 36 months and reach $600/kWh by 2015. The report argues that falling prices mean using storage systems to manage energy prices, buying energy at periods of low demand and then storing it for use during peak periods could make economic sense for large power consumers within the next year and for smaller consumers by 2016. Significant growth is also expected for pumped hydro and flywheel energy storage systems, meaning that by 2020 energy storage could be in widespread use in the UK across the transmission and distribution systems, and even co-located with wind farms and solar parks. However, BNEF warns that changes in government policy, such as allowing transmission and distribution utilities to sell stored electricity to National Grid, will be needed to realise the benefits of bringing more renewable energy online and allowing commercial users to avoid having to purchase power at the most expensive times of day."

This current figure is enough to power up to 6,000 homes. But ultimately, the entire plant should generate as much power as is used by the 600,000 people of Seville. It works by focusing the reflected rays on one location, turning water into steam and then blasting it into turbines to generate power.....
