Renewable energy, including wind, solar, biomass, biofuel, geothermal, and hydroelectric sources, accounted for 11.14% of U.S. electricity production during the first six months of 2010, according to the most recent issue of Monthly Energy Review by the U.S. Energy Information Administration (EIA). The 11.14% figure marks continued growth for U.S. renewable energy, which accounted for 10.71% of domestic electricity generation during the first six months of 2009 and 10.35% during the first six months of 2008, EIA said. The largest single renewable energy source was biomass, including biofuels, which accounted for 50.66% of renewable energy production over the first half of 2010, followed by hydropower at 32.56%.
EIA pointed out that the contribution of renewable energy sources to U.S. electricity generation is now almost equal to that of nuclear power, which accounted for 11.19% during the first half of 2010—a decline of 1.3% compared with the first six months of 2009. Electricity generation from non-hydroelectric renewable sources continues to grow rapidly, EIA reported. According to EIA data, electricity from biomass, geothermal, solar, and wind during the first six months of 2010 increased by 13.0% over the amount generated during the first half of 2009.
