Approximately a quarter of the total electricity generated in the U.S. is used for lighting, according to the U.S. Department of Energy.

The Biennial Solar Decathlon, which pits some of the world’s best engineering students against one another, has culminated with Team Germany’s “Cube House” being declared the winner, says an October 16 press release from the U.S.

A California-based company is working to make algae an answer to cut manufacturing pollution and reduce the amount of plastics that end up in the landfill.

Soaking in outdoor hot tubs warmed by geothermal heat has been part of Icelandic life as much as drinking aquavit, so it comes as no surprise that Bank of Iceland, Íslandsbanki, is focusing on geothermal development in the U.S.

These days more and more homes and businesses are being lit by mercury-containing compact fluorescent lights (CFL). While they represent a much better alternative than traditional incandescent light bulbs and last up to 10 or 15 times longer than regular “Edison” bulbs, the cleanup process after a bulb break can be dangerous and complicated.

The Arctic ice caps are melting at a faster rate than scientists had predicted, a rate in which there will be little ice present within the next decade and is expected to melt completely within the next 20 to 30 years, according to expedition leader, Pen Hadow.

Last week, leaders from the world's two biggest democracies met in Washington D.C. to discuss opportunities to collaborate on catalyzing innovation in efficiency and cleantech.

A Michigan township outside of Detroit on Sept. 17 erected a wind- and solar-powered streetlight, making it possibly the first community in the country to boast a hybrid public light.

Biomass is an organic matter that can be used to make fuels, chemicals and other products, as well as provide heat or electricity. For example, wood is one of the oldest and most commonly used examples of biomass. Burning it produces heat to give us warmth.

Although China’s per-capita carbon dioxide emissions are relatively low, their giant population makes them the number one country in the world when it comes to total carbon dioxide emissions.
