Coal was the thirdlargest energy source for electricity generation in 2022—about 18%. Nearly all coalfired power plants use steam turbines. A few coalfired power plants convert coal to a gas for use in a gas turbine to generate electricity. Petroleum was the source of less than 1% of electricity generation in 2022.
