Coal was the third-largest energy source for U.S. electricity generation in 2020—about 19%. Nearly all coal-fired power plants use steam turbines. A few coal-fired power plants convert coal to a gas for use in a gas turbine to generate electricity.
How many power plants are coal?
In 2019 there were 241 coal powered units across the United States which generated 23% of the United States electricity in 2019, an amount of electricity similar to that from renewable energy or nuclear power but about half of the amount generated by natural gas plants. Installed capacity was about 236 GW.
Does coal fuel most electric plants?
Coal is the most-used electricity generation source in 18 states; natural gas in 16. Electricity generators that use fossil fuels continue to be the most common sources of electricity generation in most states.
How long will coal power last?
Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.

Why coal is the best energy source?
Coal is a stable, secure energy source
Coal also has the unique advantage of being able to be stored on-site, providing weeks or even months of fuel supply at the power plant. This important characteristic contributes to grid reliability, resiliency and reduces fuel supply bottlenecks.
What are the disadvantages of using coal?
The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
What is the most used power source?
Natural gas was the largest source—about 40%—of U.S. electricity generation in 2020. Natural gas is used in steam turbines and gas turbines to generate electricity. Coal was the third-largest energy source for U.S. electricity generation in 2020—about 19%.
