Clean energy could lead to scarce materials

As the world moves toward greater use of low-carbon and zero-carbon energy sources, a possible bottleneck looms, according to a new MIT study: the supply of certain metals needed for key clean-energy technologies.

Electrifying new way to clean dirty water

(PhysOrg.com) -- University of Utah researchers developed a new concept in water treatment: an electrobiochemical reactor in which a low electrical voltage is applied to microbes to help them quickly and efficiently remove ...

Egyptian method filters seawater in minutes

Researchers at Alexandria University in Egypt have unveiled a cost-effective desalination technology which can filter highly salty water in minutes.

Scientists say cost of capturing CO2 declining

Technology now in limited use removes about 90 percent of carbon dioxide from the smokestacks of coal-fired power plants, but energy experts say cost remains the chief obstacle to bringing the "clean coal" touted by President ...

Renewable energy costs falling: agency

Power from renewable energy sources is getting cheaper every year, according to a study released Wednesday, challenging long-standing myths that clean energy technology is too expensive to adopt.

A lung-inspired design turns water into fuel

Scientists at Stanford University have designed an electrocatalytic mechanism that works like a mammalian lung to convert water into fuel. Their research, published December 20 in the journal Joule, could help existing clean ...
