U.S. electric power sector emissions totaled 1,744 million metric tons in 2017, the lowest since 1987, according to an Oct. 29 report from the U.S. Energy Information Administration. Energy-related emissions in the power sector fell by 28 percent since 2005 compared to 5 percent in all other energy sectors. The agency attributed the drop in power sector emissions to slower electricity demand growth and changes in the generation mix. Electricity demand fell in six of the past 10 years as industrial demand dropped and residential demand has been flat. Less-carbon intensive natural gas has been displacing coal and gaining share in the power mix. Increases in generation from non-carbon resources such as wind and solar have also contributed to the emissions reductions.
