Thermal power generation is a process that converts heat energy into electrical energy. This is typically achieved by burning fossil fuels like coal, natural gas, or oil to produce steam. The steam drives a turbine connected to a generator, which then produces electricity. In addition to fossil fuels, nuclear power plants also use thermal energy, but they generate heat through nuclear fission instead of combustion. The generated electricity is then transmitted through power lines to homes and businesses, making thermal power a significant source of energy worldwide.
