In 2024, the United States consumed about 94 quadrillion British thermal units (quads) of energy, a 1% increase from 2023, according to our Monthly Energy Review. Fossil fuels—petroleum, natural gas, and coal—accounted for 82% of total U.S. energy consumption in 2024. Nonfossil fuel energy—from renewables and nuclear energy—accounted for the other 18%. Petroleum remained the most-consumed fuel in the United States, as it has been for the past 75 years, and nuclear energy consumption exceeded coal consumption for the first time ever.
