While U.S. clean energy installations lagged, a record amount of capacity brought online in 2016 drove generation from renewables in 2017 to its highest level ever, at 18 percent of the overall energy mix. Natural gas and coal still remain the top producers of U.S. electricity, but both sources experienced a slight dip in 2017. Natural-gas generation dropped 2 percent, while coal fell 3 percent. Renewables are making a lot of headway in pushing forward the decarbonization of the power sector, even as the natural gas share decreases, but natural gas still remains the largest single contributor to the electricity mix.
