The latest figures from the Energy Information Administration show that net U.S. electrical generation from renewable energy sources (biomass, geothermal, solar, water, wind) reached an all-time monthly high in May 2009. Combined, those sources accounted for 13 percent of total electrical generation in the U.S., according to recent analysis from the Washington, D.C.-based Sun Day Campaign.

"Non-hydro renewables are already well beyond the levels of the Renewable Electricity Standard proposed in energy legislation now being considered by before the U.S. Senate, which calls for just 3 percent renewables by 2013." -- Kenneth Bossong, Executive Director, Sun Day Campaign
