U.S. Energy Information Administration, October 31, 2012

 

According to the latest issue of EIA's "Electric Power Monthly," with data through to August 31, 2012, net electrical generation from non-hydro renewable energy sources (i.e., biomass, geothermal, solar, wind) was 12.95% higher during the first eight months of the year compared to the same period in 2011. In total, those sources have accounted for 5.25% of U.S. net electrical generation thus far in 2012 compared to 4.57% during the first two-thirds of 2011. Combined with conventional hydropower, renewable sources have accounted for 12.50% of net U.S. electrical generation since January 1, 2012. However, hydropower output is 14.16% lower in 2012 than it was in 2011.
