On the Isle of Islay, a 250kW wave-powered generator produces enough electricity to power 500 homes. It is clean and renewable and uses no fossil fuels. Out to sea, the 'Pelamis', an alternative wave-powered generator, which floats on the ocean surface, produces electricity. Renewable energy makes the most of what nature has to offer. Scotland already produces hydroelectricity and has some large wind farms, the most recent being located in the Moray Firth.
