The electric power sector consists of facilities which generate electricity primarily for use by the public. Energy is used for the generation, distribution, and transmission of electric power.
Between 2019 and 2020, electric power sector energy use decreased 4.5 percent to 368.5 trillion British thermal units (Btu). Renewable energy use increased 21.1 percent. Nuclear electric power use decreased 11.0 percent, coal use decreased 10.9 percent, natural gas use decreased 10.4 percent, and petroleum use decreased 9.2 percent.
The principal fuels used at electric utilities are coal (53.89 percent), renewable energy (25.38 percent), and nuclear electric power (17.54 percent). Natural gas (3.14 percent), solar thermal and photovoltaic energy (0.13 percent), and petroleum (0.06 percent) made up the other 3.33 percent of fuels consumed. Petroleum was comprised totally of distillate fuel oil.
In 2020, if there was consumption of geothermal energy in the electric power sector, it was comparatively small and rounded to zero.
Hydroelectric power data was included in renewable fuels, but is shown separately in the graphs and data tables below.
