Greater use of natural gas for U.S. electricity generation is the leading factor in reducing carbon dioxide emissions from the power sector. Utilities have turned to low-cost, abundant and clean natural gas which today powers nearly one in three American households. Natural gas also produces just half the carbon emissions of coal.
As use of coal has fallen, and reliance on natural gas has grown, carbon emissions have tumbled. From 2005 to 2017, the amount of natural gas consumed for electricity generation grew by more than 56 percent. Natural gas is now the leading fuel for U.S. electricity generation.
