Hero of Alexandria invented the first steam-driven turbine in the 1st century A.D., but a commercially practical steam turbine wasn't developed until 1884; steam turbines are now the main elements of electric power stations.

A wind turbine generates electricity by being turned by the wind; the largest now have vanes with a turning diameter of over 400 feet.
