NEW YORK, July 15 (UPI) -- The United States and Europe added more power capacity from renewable sources like wind and solar than from conventional sources in 2009, a report says.
This year or next, experts predict, the world as a whole will add more capacity to the electricity supply from renewable sources than from traditional sources such as coal, gas or nuclear plants, a report by the U.N. Environment Program said Thursday.
China surpassed the United States in 2009 as the country with the greatest investment in clean energy, the report said, with China's wind farm development enjoying the greatest investments.
Countries that encourage renewable energy have roughly doubled, the report noted, from 55 in 2005 to more than 100 today, half of them in the developing world.
In 2009 renewable sources represented 25 percent of global electrical power capacity, generating 1,230 gigawatts of the total of 4,800 gigawatts from all sources including coal, gas, nuclear, the report said.
