They used the power of the wind to spin an inner camshaft that drove a grain mill at its base. Windmills used an early gear system to transfer the energy from the sails to the camshaft and into the grain mill. The windmill was especially useful in areas where running water was scarce, as many riverside villages used a watermill for similar ...

There are two main types of hydropower turbines: reaction and impulse. The type of hydropower turbine selected for a project is based on the height of standing water—referred to as "head"—and the flow, or volume of water over time, at the site. Other deciding factors include how deep the turbine must be set, turbine efficiency, and cost.

In both cases a power source is used to turn a propellerlike piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coalfired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.
