How much carbon dioxide is produced per kilowatthour of U.S. electricity generation?

On average 0.855 pounds of CO2 emissions are produced per kWh generated.

In 2021, utility-scale electric power plants that burned coal, natural gas, and petroleum fuels were the source of about 61% of total annual U.S. utility-scale electricity net generation, but they accounted for 99% of U.S. CO2 emissions associated with utility-scale electric power generation. The other 1% of CO2 emissions were from other fuels and gases derived from fossil fuels and some types of geothermal power plants. EIA considers electricity generation from biomass, hydro, solar, and wind to be carbon neutral.
