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.

Advocates of coal power argue that it is among the cheapest sources of energy in the United States and allows for lower-cost power. But a new Harvard study found that whatever money is saved in operation costs is completely negated by the cost coal plants inadvertently pass on to the American public: $345 billion.

The capital's nuclear programme is progressing well but must now begin to pay greater attention to areas surrounding nuclear fuel supply and disposal, and protection of facilities, said a review board set up by the emirate's Government.

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?

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 demand for renewable energy is expected to triple over the next decades according to U.N.E.P.’s Year Book 2011. United Nations Environment Program’s 2011 Year Book predicts this year to be the first where low-carbon energy capacity exceeds that of fossil-fuel.

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.

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.

India was taking serious steps to promote alternative technologies that used bio-fuels and solar and wind energy, a senior official said Saturday. India also has plans to produce more bio-fuels and electric vehicles to save petrol for other vital needs, Sohail Akhtar, director in the ministry of new and renewable energy, said.

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.

The UK government has formally announced that it intends to set up a new independent statutory body to regulate nuclear power in the UK, taking over regulatory functions currently performed under the auspices of two different bodies.

The Asian Development Bank (ADB) will provide a $36.8m loan for a privately owned wind farm in Pakistan. The loan will be used by Turkish energy firm Zorlu Enerji Electrik Uretim to install wind turbines in the southern Sindh province. The wind project will cost $147m with 30% financed through equity provided by Zorlu Enerji.

A researcher at the National Institute of Standards and Technology (NIST) has invented a method of making high-temperature superconducting (HTS) cables that are thinner and more flexible than demonstration HTS cables now installed in the electric power grid while carrying the same or more current. The compact cables could be used in the electric grid as well as scientific and medical equipment and may enable HTS power transmission for military applications.

Russia has said it was ready to provide Indonesia with assistance to build its own nuclear power plant. Russian Ambassador to Indonesia Alexander Ivanov said in a press conference Tuesday that the possibility of building a nuclear plant in Indonesia was one of many issues Russia was willing to discuss in the ASEAN Regional Forum (ARF) later this year.

Environmentalists have long complained that so long as diesel or gasoline remains relatively inexpensive, there is little incentive to come up with alternative, greener energies for transportation. But the price of oil and gasoline isn't the only reason to go green. The United States Navy says they are making a tactical decision to find cleaner alternatives. Secretary of the Navy Ray Mabus says that by 2012, the military branch plans to demonstrate a carrier strike group that uses alternative fuels.

Asia leads the growth in global wind power, which grew 35.8 GW in 2010 bringing total global capacity to 194.4 GW – up 22.5% from 2009, the Global Wind Energy Council (GWEC) says. Wind power installations in 2010 represented investments worth €47.3 billion, but the global wind power market was nonetheless down for the first time in 20 years. New installations fell 7% compared to 2009, mainly due to a disappointing year in the US, as well as a slowdown in Europe.

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.
