Windmill - an overview | ScienceDirect Topics
Windmills have existed for at least 3000 years, mainly for grinding grain or pumping water. The use of windmills to generate electricity is a twentieth-century development and in the early 1970s started the development toward modern wind turbine technology. The amount of wind power systems increased by 25–30% per year between 1998 and 2011.

Wind Power Technology - Renewable Energy World
From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent – a wind turbine – can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy.
How a Wind Turbine Works - Text Version | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
