physics researchers at Virginia Commonwealth University have discovered that most of the electrolytes used in lithium-ion batteries — commonly found in consumer electronic devices — are superhalogens, and that the vast majority of these electrolytes contain toxic halogens. At the same time, the researchers also found that the electrolytes in lithium-ion batteries (also known as Li-ion batteries) could be replaced

It may come as a surprise to some, but David Owens, executive VP of the Edison Electric Institute, and Ralph Cavanagh, co-director of the Natural Resources Defense Council’s energy program, seem to have a lot in common. Owens leads the trade group representing the nation’s investor-owned utilities; Cavanagh is an attorney with an environmental organization that heavily influenced the new

Grid-scale energy storage is slowly moving from its pilot-program phase to its early commercialization phase. And the slow road to commercialization at U.S. utilities comes in the form of requests for quotation and solicitations like the one just issued by the New Jersey Board of Public Utilities, which approved a modest $3 million competitive solicitation “aimed at encouraging the development

It seems like only yesterday that the German solar company SolarWorld was leading the charge to pound China and Taiwan with solar tariffs for allegedly dumping cheap, government-subsidized solar cells on the US market. That action has touched off a slugfest among competing interests in the US solar industry, but apparently the Energy Department has stayed out of the fray.

Georgia has not done the best of the US states in adopting solar power. At the same time, it has installed about 138 MW, so it ranks 15th nationally. The state’s utility, Georgia Power, has not been very open to renewable energy, even though Georgia has very strong solar potential. Up until now, it seems most of this potential has

The blazing Sahara sun may power homes a world away by 2018. The people behind a new $13 million project called TuNur farm propose to build a massive 100-square-kilometer solar farm in Tunisia. The farm would then connect directly to the UK, pumping energy through a 280-mile-long underwater cable. The mega solar farm would be made up of thousands of
