Despite projected growth in natural gas and renewable energy use to generate electricity through 2050, in the Annual Energy Outlook 2020 (AEO2020) Reference case, the U.S. Energy Information Administration (EIA) projects that coal and nuclear power plants will collectively provide more than 25% of generation through 2050. Other scenarios with different assumptions for oil and natural gas supply—which in turn affect natural gas prices—have implications for long-term coal-fired and nuclear-powered electricity generation in the United States.
