— Coal was the fourth-highest energy source—about 16%—of U.S. electricity generation in 2023. Nearly all coal-fired power plants use steam turbines. One power plant converts coal to a gas to use in gas turbines to generate electricity. Petroleum was the source of about 0.4% of U.S. electricity generation in 2023.
