"To date, the Obama Administration has created and supported pro-solar policies that have been vital to the success of the industry. Solar installations and jobs have risen dramatically throughout the U.S, while costs have fallen. Today, the solar industry employs more than 119,000 Americans at 5,600 companies, mostly small businesses, across all 50 states – this is more than double the number of Americans working in solar in 2009. "Since President Obama took office, the amount of solar powering homes, businesses, and military bases has grown by 400 percent – from 1,100 megawatts in 2008 to more than 5,700 megawatts today. The Administration enacted a policy allowing solar installations for the first time on public lands and set a goal to permit 10 gigawatts of additional renewable energy projects on public lands by the end of 2012, which has been a great driver of this growth. The U.S. now has enough installed solar capacity to power nearly a million households, and 2012 will be another year of record growth for our industry. "Policy certainty is crucial to continue the growing role of solar in America's energy mix. Stable policy frameworks at the federal and state level, including maintaining and expanding commitments to renewable energy initiatives, spur and leverage private sector investments in the solar industry to meet our nation's future energy needs."
China has given the go-ahead for the wind energy counterpart of its massive Three Gorges dam, the world's largest. The 1.4 gigawatt (GW) wind farm in Inner Mongolia will be the largest in the country so far. Each of seven wind farms that comprise the project will be built by different developers - Huadian, Guodian, Huaneng, Longyuan, CPI, Beijing Jingneng New Energy and Xiehe Wind Power - at a total cost of $2.18 billion. Construction should be finished by the end of next year. As of 2011, Inner Mongolia had 17.6 GW of wind, providing 13.8% of the city of Baotou's electricity. Another 10 GW of wind is planned for the area. Baotou is the largest city in Inner Mongolia with about 2.3 million residents. The Chinese wind industry has been languishing waiting for the transmission infrastructure to connect projects already built.
A solar cell made entirely from carbon, one of the most abundant elements on earth, has been developed for the first time by a research team from Stanford University. The discovery opens the door to much cheaper energy generation capabilities in the future. The results are published in the Oct. 31 online edition of the journal ACS Nano. Stanford Professor Zhenan Bao says: "Photovoltaics will definitely be a very important source of power that we will tap into in the future," said study senior author Zhenan Bao, a professor of chemical engineering at Stanford University . "We have a lot of available sunlight. We've got to figure out some way to use this natural resource that is given to us." Stanford University scientists have developed the first solar cell made entirely of carbon. This new solar cell promises a cheaper alternative to the expensive, silicon-based photovoltaic solar panels available today.
The world's largest offshore wind farm produced its first electricity on Monday around 20 kilometres off the east coast of Britain, boosting the country's position as the world's top offshore wind market. The first 151 wind turbines of the London Array project generated electricity for the first time and the remaining 24 will power up by the end of the year, owners DONG Energy (50 percent), E.ON (30 percent) and Masdar (20 percent) said. Britain aims to build around 30 gigawatts (GW) of wind capacity at sea by 2020 to make use of high wind speeds for electricity generation to help meet the governments legally binding emissions reduction targets. Once the London Array project is fully operational at the end of the year, Britain will have nearly 3 GW of offshore wind capacity in operation. The London Array wind farm could be expanded to 870 MW if a second phase receives required permits, the owners said.
Photovoltaic cell efficiency may soon get a big boost, thanks to next-generation antireflection coatings crafted from nanomaterials capable of cutting down on the amount of light reflected away from a cell's surface. Materials boasting a "tunable" refractive index have been developed within the past few years, and they show tremendous potential for photovoltaic applications. Professor E. Fred Schubert, of Rensselaer Polytechnic Institute's Department of Electrical, Computer, and Systems Engineering, is investigating ways to exploit this newly gained controllability and will present his findings at the upcoming AVS 59th International Symposium and Exhibition, held Oct. 28 - Nov. 2, in Tampa, Fla. The refractive index is the property of a material that changes the speed of light, and is computed as the ratio of the speed of light in a vacuum to the speed of light through the material. Among the most fundamental properties of optical materials, the refractive index determines important optical characteristics such as Fresnel reflection, Bragg reflection, Snell refraction, diffraction, and the phase and group velocity of light. Air and other gases have a refractive index very close to 1.0, but unfortunately aren't viable for thin-film optoelectronic applications. Among transparent dense materials suitable for use in thin-film optoelectronic applications, magnesium fluoride (MgF2) has the lowest refractive index (n=1.39); no dense materials with a lower refractive index are known to exist.

According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, 433 MW of new electrical generating capacity was added in the U.S. in September -- all from solar and wind sources. The total consisted of five wind projects totaling 300 MW and 18 solar projects totaling 133 MW. For the first nine months of 2012, 77 wind projects (4,055 MW), 154 solar projects (936 MW), 76 biomass projects (340 MW), 7 geothermal projects (123 MW), 10 water power projects (9 MW), and 1 waste heat project (3 MW) have come on-line. Collectively, these total 43.8% of all new generating capacity added since the beginning of 2012. By comparison, new natural gas capacity additions since January 1, 2012 totaled 61 projects (4,587 MW) or 36.8% while 3 new coal projects added 2,276 MW (18.3%). Nuclear and oil represented just 1% and 0.1% of new capacity additions respectively. The new renewable energy generating capacity added in 2012 represents a 29% increase over the level recorded for the same period in 2011. Renewable energy sources now account for 14.9% of all installed U.S. electrical generating capacity.
The U.S. wind industry reached a milestone during the third quarter, surpassing 50 GW of total installed generation capacity, according to a new American Wind Energy Association report. The industry installed 1,832.7 MW during the quarter, bringing total wind power capacity installations to 51,630 MW. Wind capacity additions in 2012 have totaled 4,728 MW so far, AWEA said in its third-quarter market report. At least 40 electric utilities own or have contracted wind from projects currently online through the third quarter, the association said. The third quarter saw a 52% increase in installed capacity over the year-ago quarter. Twenty-seven wind projects were installed in 15 states during the quarter. The wind industry installed 40% more capacity during the first three quarters of 2012 than the same period in 2011, primarily due to developers racing against the clock to complete projects before the production tax credit, or PTC, expires. The PTC provides wind plants that are in service by Dec. 31 with a tax credit for the first 10 years of electricity production from utility-scale turbines. "This is what a successful policy looks like when it's working, but whether wind will continue to be a bright spot in the U.S. economy now depends on whether Congress acts to extend the production tax credit by the end of the year," AWEA CEO Denise Bode said in an Oct. 18 statement.
Siemens AG announced plans to give up its loss-making solar business and concentrate its renewable energy business on wind and hydroelectric power. The German industrial conglomerate, whose products range from trains to turbines, said Monday it's in talks with possible buyers, but offered no details. It said the move is part of a wider effort to increase its productivity and efficiency. The solar power industry has been hit by falling subsidies, weaker sales and increasingly stiff price competition, especially by Chinese manufacturers. Siemens said that "due to the changed framework conditions, lower growth and strong price pressure in the solar markets, the company's expectations for its solar energy activities have not been met." Several German solar manufacturers, including Q-Cells SE and Solar Millennium AG, have filed for insolvency over the past year. Another German company in the solar market, SMA AG, announced last week that it will slash up to 1,000 jobs — about a fifth of its global workforce — amid falling revenues and a possible annual loss in 2013 due to the growing price pressures.
The energetic use of solid biomass such as wood will increase to a larger extent than ever before in the years to come. At present, more than 2,200 biomass power plants are operational throughout the world. They have a total capacity of about 32,000 megawatts (MW). In Europe alone, there are more than 1,100 active biomass power plants. Another 130 coal power plants co-incinerate biomass. Over the past five years, about 150 biomass power plants went operational per year worldwide, each one with an average capacity of 11 MW, which is more than ever before. However, this growth will once more accelerate in the future: by 2016, 165 plants with an average capacity of more than 15 MW will be commissioned per year. Investments in new construction and maintenance of biomass power plants will increase from currently 10 to more than 14 billion euros annually. The trend for developing biomass follows the trend for developing renewable energies. More and more countries introduce feed-in tariffs for electricity from biomass. The increasing prices for fossil energy sources, the fact that many countries aim at increasing the use of domestic raw materials and the introduction of CO2 certificates for fossil fuels in Europe have over the past years improved the competitiveness of electricity generation from biomass.
GTM Research says many PV solar panel makers will go under or be acquired soon. The global marketplace is simply over-saturated, the company’s report states, so dramatic changes are coming. The difference in PV supply and demand could be 35 GW a year. About 88 companies are predicted to shutter PV factories, mainly in the United States, Europe, and Canada. The cost of solar panels and their manufacture has dropped so much it is simply too costly to produce them competitively in certain parts of the world. The number of companies affected by the fast-changing market conditions is huge, and very sad for the demise of their once promising ventures. “Manufacturing costs for firms in Europe, the U.S. and Japan are currently over 80 cents per watt. The cost for their Chinese competitors is between 58 cents and 68 cents per watt. The writing is on the wall: these companies will either take what they can get via acquisition or they will bow out,” said the report’s author, Shyam Mehta, Senior Analyst at GTM.
Battery maker A123 Systems, a one-time darling of the U.S. electric car industry and recipient of millions in government funding, filed for Chapter 11 bankruptcy Tuesday. The filing highlights the controversy over federal subsidies for "green energy" companies that has been a part of the 2012 presidential campaign. A123 has $144 million in debt and missed a $2.7 million interest payment on Oct. 15. In 2009, A123 received $249 million in federal funding for advanced battery technology manufacturing at two sites in Michigan -- Romulus and Brownstown. The funding was part of $2.4 billion in stimulus funds designed to jump start advanced vehicle manufacturing in the United States.
The American Wind Energy Association (AWEA) with support from the US Energy Department and National Renewable Energy Laboratory, has developed a set of recommended practices for using existing standards to plan, design, construct and operate offshore wind facilities in compliance with federal and state regulations. The recommended practices drawn up by AWEA’s Standards Development Board cite four levels of existing standards: international, American National Standards, classification society such as DNV, Germanischer Lloyd and The American Bureau of Shipping standards, and commercial standards and guidelines, These standards address five critical areas: structural reliability; manufacturing, qualification testing, installation, and construction; safety of equipment; operation and inspection, and decommissioning. The 63-page Recommended Practices for Design, Deployment, and Operation of Offshore Wind Turbines in the United States was unveiled at AWEA’s offshore windpower conference here.
Interior Secretary Ken Salazar on Tuesday authorized what he described as potentially the largest wind energy project in the United States, if not the world: A Wyoming wind farm with up to 1,000 turbines that would provide electricity to some 1 million homes. Roadwork and groundwork could begin next year for the Chokecherry and Sierra Madre Wind Energy Project. After that, turbines could go up over a three-year period within an area covering 350 square miles of the hilly sagebrush country south of Rawlins in south-central Wyoming. Most of that area is among the 245 million acres nationwide overseen by the U.S. Bureau of Land Management — hence Salazar's role. Salazar highlighted the project as an example of President Barack Obama's "all of the above" strategy for renewable energy development and fossil fuel extraction on BLM and other public lands.
The Commerce Department issued its final ruling Wednesday in a long-simmering trade dispute with China, imposing tariffs ranging from about 34 percent to nearly 47 percent on solar panels imported from the country. For most of the Chinese manufacturers, the penalties are somewhat higher than those announced by the Obama administration earlier this year, when the government determined that Chinese companies were benefiting from unfair government subsidies and were selling their products below the cost of production, a practice known as dumping, on the American market. For the biggest panel maker, Suntech, the duties are significantly higher, moving to almost 47 percent from about 33 percent. The trade case stemmed from a legal filing nearly a year ago by a coalition of manufacturers, led by SolarWorld, a German company with considerable manufacturing in the United States. The coalition contended that Chinese companies, which dominate global sales with a two-thirds market share, were competing unfairly in the American market.
