Solar Junction is a 4-year-old company spun out of Stanford University that designs high-efficiency, multi-junction solar cells for concentrating photovoltaic (CPV) solar collectors. The National Renewable Energy Laboratory recently certified that its solar cells can operate at 40.9% efficiency, a significantly higher efficiency than typical silicon solar cells that convert sunlight to electricity at an efficiency of about 15-20%.

Scientists are reporting development of an advanced lithium-ion battery that is ideal for powering the electric vehicles now making their way into dealer showrooms. The new battery can store large amounts of energy in a small space and has a high rate capacity, meaning it can provide current even in extreme temperatures.

France's consumption rose by 7% – and in Europe only Denmark and Ireland used less energy per unit of GDP than UK.The EU energy commissioner, Günther Oettinger, is expected to recommend member states are set individual targets on efficiency improvements.The UK is one of the top performers in Europe on energy efficiency, according to a European commission report.

Wind turbine prices last year fell below 1 million euros ($1.4 million) a megawatt for the first time since 2005, Bloomberg New Energy Finance said. Global turbine contracts signed in the last six months of 2010 for delivery this year averaged 980,000 euros a megawatt, the London-based analyst said today in a statement. That’s down from 1.06 million euros for contracts signed in 2009 and a peak of 1.21 million euros in 2007 and 2008, the group said.

The Umeox Apollo is named after the Greek Sun God, and comes with a built-in solar panel covering the rear of the phone allowing the user to place a call when the batteries are discharged, provided there is sufficient sun available. Daily usage recharge needs about 2.5 hours of sunlight with a complete recharge requiring 17 hours.

CyberSmart Africa implements a practical and scalable solution to enlighten the frequently ignored rural schools with contemporary education. Funded by the United States Agency for International Development (USAID), CyberSmart’s “tech-lite” approach, which includes a specially adapted interactive whiteboard and other low-power digital tools, puts learning first. The system uniquely focuses on teacher training and puts the latest low-power, portable equipment to work directly in the classrooms of off-the-grid rural schools.

Clearing up the regulatory hurdles that are slowing development of electricity transmission lines would provide a significant boost to U.S. wind power development, industry officials said Wednesday. The American Wind Energy Association is holding a two-day workshop in Omaha focused on the challenges of transmitting power to places that need it. The biggest regulatory barriers have to do with who pays for high-voltage transmission lines and who decides where the lines will go.

Until last year, wind power appeared immune to the worst ravages of an economic storm sweeping the globe. Then the world's biggest manufacturer of wind turbines took an axe to 3000 jobs in its native northern Europe. Did it signify not just a readjustment to a single producer's business model but a threat to the technology's continuing worldwide deployment? Or, as some believe, are fears of a decline in the sector's fortunes simply overblown?

Năm nay, Geoplasma dự định xây dựng một nhà máy với chi phí 120 triệu USD ở California (Mỹ). Rác thải từ các hộ gia đình địa phương cung cấp cho nhà máy sẽ tạo ra lượng syngas đủ để sản xuất điện phục vụ hơn 20.000 gia đình.

Các nhà khoa học thuộc đại học tổng hợp Cornell đang có hi vọng dùng một số loại vi khuẩn trong chất thải nhà máy bia để sản xuất xăng sinh học và các sản phẩm hữu ích khác. Largus T. Angenent, phó giao sư ngành kỹ thuật sinh học và môi trường, tác giả chính cùng trợ lý Jeffrey J. Werner gần đây đã đăng một bài viết về nghiên cứu của mình trên tạp chí Proceedings of the National Academy of Sciences (Biên bản của Viện hàn lâm khoa học quốc gia).

Gaining new insight into how efficiently the microbes in large bioreactors produce methane from brewery waste, Cornell scientists hope to use their new knowledge to shape these microbial communities to produce liquid biofuels and other useful products.

The global market for LED light fixtures, which already stood at $3.8bn in 2010, is expected to grow to $8.3bn within the next three years, according to new research. The heightened awareness of energy efficiency together and global fiscal stimulus has created suitable conditions for the adoption of white light application of LED technology, which would otherwise have faced high costs.

Deputy Prime Minister Hoang Trung Hai has directed the MOIT to soon complete and submit to the Government the mechanism issuing regulations to support, facilitate and encourage wind power projects in Vietnam.

Thus, from March 1st, the average price of electricity will increase from 1,077vnd/kWh to 1.242vnd/kWh, equivalent to a 15.28% increase. With this increase, many of EVN’s costs shall continue to be kept from being allocated to the price, the rate of return on state capital of EVN is zero and coal price has not risen in the electricity price structure.

Automobiles, military vehicles, even large-scale power generating facilities may someday operate far more efficiently thanks to a new alloy developed at the U.S. Department of Energy's Ames Laboratory. A team of researchers at the Lab that is jointly funded by the DOE Office of Basic Energy Sciences, Division of Materials Sciences and Engineering and the Defense Advanced Research Projects Agency, achieved a 25 percent improvement in the ability of a key material to convert heat into electrical energy.

Solar power could be on the brink of economic breakthrough, reaching investment levels of €70 billion in 2015, according to a major study out this week. The report, Solar Generation 6, by the European Photovoltaic Industry Association (EPIA) and Greenpeace International estimates that photovoltics could meet 12% of European demand by 2020 and up to 9% of the world’s demand by 2030.

Will electric car charging networks have the type of roaming commonly found between cell phone providers? If Nokia Siemens Networks– a joint venture between the European networking giants — has anything to say about it, in Europe they will. This week at Mobile World Congress (MWC), an annual telecom conference in Barcelona, Nokia Siemens and a German public utility group called Smartlab announced they are developing an authentication and authorization service to enable electric vehicle drivers to “roam” when charging up via various service providers.

Đó là một trong những kết luận của bản báo cáo Solar Generation 6 trong cuộc nghiên cứu do Hiệp hội Công nghiệp Quang điện Châu Âu (EPIA) và Greenpeace International thực hiện. Theo ước tính của nghiên cứu này, quang đện có thể đáp ứng 12% nhu cầu của châu Âu tới năm 2020 và 9% nhu cầu toàn thế giới tới năm 2030.

Drayson Racing and Aston University have announced a collaboration to develop and demonstrate low carbon automotive technologies. The partnership will investigate 'second generation' biofuels produced from waste biomass such as straw, wood and sewage sludge to create high performance cars with reduced CO2 emissions.

France’s solar-panel imports surged last year as developers relied mostly on foreign manufacturers to supply a boom in renewable-energy projects, Environment Minister Nathalie Kosciusko-Morizet said. French customs figures show the deficit in favor of solar panel imports widened to 1.5 billion euros ($2.1 billion) in 2010 compared with 800 million euros the previous year, she said at a conference in Paris.
