What is coal used for?
Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United

· The technology to capture CO2 is relatively simple, and has been in use since the 1930s. For example, CO2 can be captured from the smokestacks of coal plants, natural gas plants, and even factories by routing the flue gases through an amine chemical bath, which binds the CO2. The chemical is then heated to release the CO2.

oil shale | National Geographic Society
Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar hydrocarbons. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas.
Globally, fossil fuels account for a much smaller share of electricity production than the energy system as a whole. In 2019, around 64% of our electricity came from fossil fuels. This interactive map shows the share of electricity that comes from fossil fuels (coal, oil and gas summed together) across the world.
