What do Windmills do? A windmill is a structure used to harness the power of the wind for purposes like grinding grain, pumping water, and generating electricity. Wind causes its blades to spin, thereby creating kinetic energy. The spun blade turns a shaft, which …
The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can …
The first true windmill, a machine with vanes attached to an axis to produce circular motion, may have been built as early as 2000 B.C. in ancient Babylon. By the 10th century A.D., windmills with wind-catching surfaces as long as 16 feet and as high as 30 feet were grinding …
Windmills were further developed to automate the tasks of grain-grinding and water-pumping.The earliest design was the vertical axis system. It was developed in Persia around 500-900 A.D. Grain grinding was the first recorded windmill application. A grinding stone was affixed to the vertical shaft to grind …
History of Windmills. Windmills represent one of the key pieces of technology that enabled our ancestors to transform the power of the wind into a physical force that can be used for countless things, from most traditional jobs such as grinding grains and moving water, to the many more industrial and agricultural needs.
A windmill is a structure or machine that converts wind into usable energy through the rotation of a wheel made up of adjustable blades. Traditionally, the energy generated by a windmill has been used to grind grain into flour. Windmills are designed by skilled …
Traditionally windmills were used on farms to pump water or grind grain. Today's windmills or wind turbines can use the wind's energy to generate electricity. A windmill on a farm only makes a small amount of electricity. To make enough electricity to serve lots of people, utility companies build wind farms with a large number of wind turbines.

Grinding Grain. Windmills were first used many centuries ago to help grind grain, and they still were being used for that task in the 1800s. Such windmills had sails attached to a vertical shaft, which in turn was attached to a grinding stone; as the sails turned the stone, the grain was ground.
