From algae to alloys, ingenuity in the world’s laboratories is fueling experiments to find new ways of providing viable sources of clean energy.
As electricity from renewable sources tops 25 percent in the U.K., the government is challenged to create a level playing field by scrapping nuclear and fossil-fuel subsidies.
Researchers have developed a battery that uses a common food additive to enable abundant solar and wind power to be stored cheaply and safely in homes and offices.
By adapting a tropical grass to grow in the British climate, scientists hope to be able to replace coal in power stations with biofuel.
New research shows that saving the planet from global warming by combining renewables and energy efficiency will also save money and create jobs.
Environmental assessment of a proposed hydroelectric dam in Canada sheds new light on the cause of high levels of a potent neurotoxin in Arctic marine life.
Massive solar power stations are being built in the world’s “sun belts” -- with the U.S. and India competing to have the largest in the world.
The use of poor-quality coal in Chinese power plants means that the carbon dioxide emissions of the world’s biggest polluter are 10 percent less than previously thought.
The Chinese are planning to come to the aid of a nuclear industry so short of funds that it cannot build any new generating plants without outside help.
Innovative turbines designed in the U.K. aim to harness tidal energy to produce cheaper electricity -- without endangering marine life.
