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.
the lignite- and hard coal–fired power plants are less flexible in most cases. 1, 20 In contrast and regarding the reviewed years 2016 to 2018, their levelized costs of electricity (LCOE) in Germany are significantly lower than the LCOE of gas. 28 However, this may change with fluctuating gas prices and more expensive CO 2 Emission ...
Coal–biomass co-firing power plants with retrofitted carbon capture and storage are seen as a promising decarbonization solution for coal-dominant energy systems.
