<P> Almost all commercial electrical power on Earth is generated with a turbine , driven by wind , water , steam or burning gas . The turbine drives a generator , thus transforming its mechanical energy into electrical energy by electromagnetic induction . There are many different methods of developing mechanical energy , including heat engines , hydro , wind and tidal power . Most electric generation is driven by heat engines . The combustion of fossil fuels supplies most of the energy to these engines , with a significant fraction from nuclear fission and some from renewable sources . The modern steam turbine ( invented by Sir Charles Parsons in 1884 ) currently generates about 80 % of the electric power in the world using a variety of heat sources . Turbine types include : </P>
