The year 2015 represented a major turning point for electricity generation in the United States. The country retired 14 GW of fossil-fueled generation. Meanwhile, it brought online 16.4 GW of carbon-free generation, with wind energy leading the mix at 8.5 GW of new installed capacity, according to BNEF’s Sustainable Energy in America 2016 Factbook.
Natural gas, despite historical low commodity prices, brought online just 6 GW. This is an exciting sign of a changing tide, but the U.S. bulk power fleet today totals ~1,100 GW of capacity, and two-thirds of generation still comes from fossil fuels. Renewables still have much ground left to cover.
