Electricity from natural gas. View of a modern gas-fired power station. In the foreground are pipes which carry cooling water to the plant. This power station is one of the new combined-cycle types,and produces about 220 MW (megawatts) of electricity. The gas is burnt in a turbine,like a jet engine,which drives a generator. The hot exhaust gases are then used to boil water,the steam passing through a second turbine and generator. In a combined heat and power (CHP) system,the water would then be piped away to provide domestic or industrial heating. This 'double' use of the gas gives a very high thermal efficiency.
