<P> A fossil fuel power station is a power station which burns fossil fuel such as coal , natural gas , or petroleum to produce electricity . Central station fossil fuel power plants are designed on a large scale for continuous operation . In many countries , such plants provide most of the electrical energy used . Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy , which then operates an electrical generator . The prime mover may be a steam turbine , a gas turbine or , in small plants , a reciprocating internal combustion engine . All plants use the energy extracted from expanding gas , either steam or combustion gases . Very few MHD generators have been built which directly convert the energy of hot , moving water into electricity . MHD means Magnetohydrodynamics , which is the study of the magnetic properties of electrically conducting fluids . Examples of such magnetofluids include plasmas , liquid metals , salt water and electrolytes . </P>
