Renewable energy – including wind, solar and biomass resources – accounted for all new generating capacity added in the U.S. in January, according to the Federal Energy Regulatory Commission's (FERC) latest Energy Infrastructure Update.
The 1.231 GW of new U.S. electrical generating capacity entering service in January represented nearly a threefold increase in new renewable energy generating capacity compared to January 2012, when wind, solar and biomass provided 431 MW of new capacity.
Wind energy accounted for the largest share of the new capacity in January, with six new units providing 958 MW, followed by 16 units of solar (267 MW) and six units of biomass (6 MW). No new generating capacity was reported for any fossil fuel (i.e., natural gas, coal, oil) or nuclear power sources.
Renewable sources now account for 15.66% of total installed U.S. operating generating capacity, and wind energy represents 5.17% of the total. Other renewable resources include water (8.5%), biomass (1.29%), solar (0.38%) and geothermal (0.32%). In comparison, natural gas accounts for 42.37% of total operating generating capacity, followed by coal (29.04%), nuclear (9.23%) and oil (3.54%).
