According to the latest 'Energy Infrastructure Update' report from the Federal Energy Regulatory Commission's Office of Energy Projects, 10,717MW of new domestic electrical generating capacity has been installed in the first nine months of this year. Renewable energy sources (biomass, geothermal, solar, water, and wind) accounted for 3,218MW (30.03%) of this total.
This is more than the generation capacity provided thus far this year by coal, oil, and nuclear power combined, which accounted for 1,543MW (14.40%), 27MW (0.25%), and 0MW (0.00%), respectively. However, natural gas dominated the first nine months of 2013 with 5,854MW (54.62%) of new installed capacity.
Among renewable energy sources, solar is leading the way so far this year with 146 new 'units' totaling 1,935MW. Solar is followed by wind with 9 units totaling 961MW and Biomass added 57 new units totaling 192MW. Water had 11 new units with an installed capacity of 116MW and geothermal steam had one new unit of 14MW.
The newly installed capacity provided by solar is only surpassed by natural gas, which had 51 units totaling 5,854MW installed. The new solar capacity in Q1-Q3 2013 is 77.36% higher than in the same period in 2012.
Actual net electrical generation from renewable energy sources in the U.S. now accounts for 15.68% of total installed U.S. operating generating capacity: water 8.32%, wind 5.18%, biomass 1.31%, solar 0.54%, and geothermal steam 0.33%. This is more than nuclear (9.19%) and oil (4.06%) combined.
