Coal is put in a massive chamber, where it is ignited. As it burns, it heats up water flowing nearby in pipes. The heat is absorbed by the water, which turns into highpressure steam. This steam is used to propel turbines into spinning at high speeds, turning huge magnets they are attached to. These are what produce the electric current that is ...

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...

Electricity generation from coal in the United States fell 20 percent in 2020, bringing it to its lowest point since 1972. Even so, coal generated percent of the country's power, roughly the same as nuclear power ( percent), and almost twice as much as the electricity generated by wind and solar. Coal is far from finished in the ...

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. Residual fuel oil and petroleum coke are used in steam turbines.

Electric vehicles (EVs) have no tailpipe emissions. Generating the electricity used to charge EVs, however, may create carbon pollution. The amount varies widely based on how local power is generated,, using coal or natural gas, which emit carbon pollution, versus renewable resources like wind or solar, which do not.

In both cases a power source is used to turn a propellerlike piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coalfired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.

Hydrogen production is the family of industrial methods for generating hydrogen gas. There are four main sources for the commercial production of hydrogen: natural gas, oil, coal, and electrolysis of water; which account for 48%, 30%, 18% and 4% of the world's hydrogen production respectively. Fossil fuels are the dominant source of industrial hydrogen.

Generating Electricity from Oil or Natural Gas. Natural gas is burned to produce electricity following the same general process used in a coal power plant (figure (PageIndex{n})). Oil is occasionally used to generate electricity as well. Figure (PageIndex{n}): This combustion chamber burns either natural gas or oil.

Two of the power plant's four coalburning units have already retired and the last is planning to shut down in 2025. "AES Indiana will be the first utility out of coal in the state," said Kelly Young, a spokeswoman for the company, which has more than half a million customers in the Indianapolis area. Power generation, however, will continue.
