The recent shift in the United States from coal to natural gas for electric power has reduced the carbon dioxide emissions intensity of electric power production, but the other pollution-related impacts of this shift are not yet known. This study finds that, between 2005 and 2016, decommissioning coal-fired plants in the continental US saved an estimated 26,610 lives and 570 million bushels of corn, soybeans and wheat in their vicinities and also changed regional climate.
