How Does A Nuclear Power Plant Make Electricity? | NRC.gov
So if you pump water through some sort of a heat source — like a nuclear reactor, or a coal‑fired boiler — that is hot enough to boil the water, the exiting steam will be travelling much faster than the water going in. That steam runs through a machine called a turbine, which acts something like a highly‑sophisticated windmill.

Coal-fired power generation
Coal- and oil-fired process. Coal- and oil-fired steam power plants have steam turbines to convert the heat energy of combustion into mechanical energy, which then operates an electric generator. All plants use the steam turbine for the drop between the high pressure and temperature of the steam and the lower pressure of condensing vapor.

Electricity explained
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.

How a Nuclear Reactor Works
In most power plants, you need to spin a turbine to generate electricity. Coal, natural gas, oil and nuclear energy use their fuel to turn water into steam and use that steam to turn the turbine. Nuclear plants are different because they do not burn anything to create steam. Instead, they split uranium atoms in a process called fission.
