1 An energy-consuming sector that consists of electricity-only power plants and combined-heat-and-power plants whose primary business is to sell electricity, or electricity and heat, to the public.
2 Preliminary data for 2015.
3 Includes CO2 emissions from the combustion of miscellaneous waste materials made from fossil fuels and by some types of geothermal power generation.
Monthly Energy Review, Tables 12.1 and 12.6 contain the most recent estimates of monthly and annual U.S. energy-related CO2 emissions, total and by the electric power sector.
