This number can be compared to the 11.98% of energy that nuclear energy contributes to in USA. According to the SUN DAY Campaign the total consumption of nuclear power dropped by 1% during the first half of 2008 while the renewable energy increased by 5%.
"The significant contribution being made by renewable energy sources to the nation's energy supply documented by the U.S. Energy Information Administration (EIA) is far greater than most Americans realize," said Ken Bossong, Executive Director of the SUN DAY Campaign. "Repeated statements by nuclear and fossil fuel interests that renewables contribute only a tiny fraction of the nationâ€™s energy supply are not only misleading but flatly wrong."
In these 10% biomass and biofuels accounts for the largest amounts of renewable energy shortly followed by hydropower. Wind power increased by almost 49% from the first half of 2007 compared to the first half of 2008. Solar and geothermal energy were at roughly the same levels in 2008 as they were in 2007. Although many predict that their share of the market will significantly increase in the near future.
