2 Renewable Energy Provides Half of All New US Electrical Generating Capacity in 2012 By Kenneth Bossong, SUN DAY Campaign January 17, 2013 Washington DC -- According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, renewable energy sources (i.e., biomass, geothermal, solar, water, wind) accounted for 49.10% of all new domestic electrical generating capacity installed in the twelve months of 2012 for a total of 12,956 MW. More than a quarter of that new capacity (25.29% - 3,276 MW) came online in the month of December 2012 alone. Wind led the way in 2012 with 164 new "units" totaling 10,689 MW followed by solar with 240units totaling 1,476 MW. Biomass added 100 new units totaling 543 MW while geothermal steam and water each had 13 new units with installed capacities of 149 MW and 99 MW respectively. SOURCE:
