Renewables and Carbon Dioxide Emissions

  • EIA expects the share of U.S. total utility-scale electricity generation from natural gas-fired power plants to rise from 32% in 2017 to 34% in 2018 and 2019. The forecast electricity generation share from coal averages 28% in 2018 and 2019, down from 30% in 2017. The nuclear share of generation was 20% in 2017 and is forecast to be 20% in 2018 and 19% in 2019. Nonhydropower renewables provided slightly less than 10% of electricity generation in 2017 and are expected to provide more than 10% in 2018 and nearly 11% in 2019. The generation share of hydropower was 7% in 2017 and is forecast to be about the same in 2018 and 2019.
  • In 2017, EIA estimates that wind generation averaged 697,000 megawatthours per day (MWh/d). EIA forecasts that wind generation will rise to 746,000 MWh/d in 2018 and to 777,000 MWh/d in 2019. If factors such as precipitation and snowpack remain as forecast, conventional hydropower is forecast to generate 752,000 MWh/d in 2019, which would make it the first year that wind generation exceeds hydropower generation in the United States.
  • After declining by 0.9% in 2017, EIA forecasts that energy-related carbon dioxide (CO2) emissions will rise by 1.1% in 2018 and by 0.2% in 2019. Energy-related CO2 emissions are sensitive to changes in weather, economic growth, energy prices, and fuel mix.
