The windmill was created to replace animal power in grinding grain. Like a watermill, the windmill could grind at least 1,000 bushels of grain per week and 6 bushels an hour based on the performance of the wind. Around the 11th-12th centuries, in England, the windmill would come into existence, conceivably by returning Christian crusaders ...

Windmills used for grinding tend to be larger than other types of windmills because they need space to house the grinding stone. Today windmills are generally used for pumping water or generating electricity. Windmills that pump water are called wind pumps and are used in dry and arid places to pump water from under the ground.

wind could be used as a source of energy for grinding corn, pumping water and other similar applications. The wind is a free, clean, and inexhaustible source of energy. It has served mankind well for many centuries. The first practical application of wind energy was witnessed in 4000 BC in the form of a single square sail on a sailing ship.

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.

By 200 BC, simple wind-powered water pumps were used in China, and windmills with woven-reed blades were grinding grain in Persia and the Middle East. New ways to use wind energy eventually spread around the world. By the 11th century, people in the Middle East were using wind pumps and windmills extensively for food production.

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. At 100 feet (30 meters) or more ...

This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. 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.

Likewise, the technique of grinding grain between stones to produce flour is similarly ancient, and widespread. Quite where and when these two came together in the first windmill is unknown, but a likely scenario suggests a Persian origin, from where (tradition has it) the knowledge spread back into Northern Europe as a result of the Crusades.

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.

The first windmill ever used to generate electricity (wind turbine) was in 1887 in Cleveland, Ohio, designed by inventor and electrician Charles F. Brush. Today, most wind devices that we see are wind turbines, which generate electricity, but in some areas windmills are still used for grinding or pumping water.

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.

The wind turns the blades of windmills, and as they rotate on the axle, it makes the gears and cogs inside of the windmill turn. In a windmill used for making flour, this turns the grinding stones. In a windmill used for pumping water, turning the axle moves a piston or a screw.
