Primary energy consumption totaled 93 quadrillion British thermal units (quads) in the United States in 2020, or 7 quads less than in 2019. Fossil fuels— specifically petroleum, natural gas, and coal— accounted for 79% of total U.S. energy consumption in 2020. About 21% of U.S. energy consumption in 2020 came from nonfossil fuel sources such as renewables and nuclear— the highest share since the early 1900s, according to data in our Monthly Energy Review.
