CO2 emissions from the U.S. power sector down 28%

CO2 emissions from the U.S. power sector down 28%

U.S. electric power sector carbon dioxide emissions (CO2) have declined 28% since 2005 because of slower electricity demand growth and changes in the mix of fuels used to generate electricity. EIA has calculated that CO2 emissions from the electric power sector totaled 1,744 million metric tons (MMmt) in 2017, the lowest level since 1987, Caspian Energy News ( reports with reference to the U.S. Energy Information Administration (EIA).

In the United States, most of the changes in energy-related CO2 emissions have been in the power sector. Since 2005, as power sector CO2 emissions fell by 28%, CO2 emissions from all other energy sectors fell by only 5%.

U.S. electricity demand has decreased in 6 of the past 10 years, as industrial demand has declined and residential and commercial demand has remained relatively flat.

In 2016, natural gas generation surpassed coal as the largest source of electricity generation.

Increases in electricity generation from noncarbon power sources since 2005 had an effect on emissions from power generation. In 2005, noncarbon sources accounted for 28% of the U.S. electricity mix. By 2017, that share had grown to 38%. Almost all of this growth was in renewables, including wind and solar, as shares for other noncarbon sources such as nuclear and hydroelectricity remained relatively flat.
