Fossil fuel power plants refer to electricity generating facilities that use coal, oil or natural gas as their primary fuel source. These plants typically involve the combustion of fossil fuels to produce heat, which is then used to generate steam that drives a turbine connected to an electrical generator. The resulting electricity is then distributed to homes and businesses through the power grid. Fossil fuel power plants are a major source of energy production around the world, but they also have significant environmental impacts due to the emissions of greenhouse gases and other pollutants.
