Answer: Renewables! According to an article on RenewableEnergyWorld.com written by Ken Bossong of the Sun Day Campaign, renewable sources such as biofuels, biomass, solar, wind, geothermal, and hydroelectric make up 11.14% of the electricity produced in the U.S. today. In fact, the electricity produced by renewable sources is now almost equal to that produced by nuclear power. According to the article, the U.S. Energy Information Administration (EIA) shows that, along with hydroelectric energy production, ”electrical generation from non-hydro renewable sources continues to grow rapidly. 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.” To read the full article, click here.
