Windmills and other spinning wind-energy devices - more accurately known as wind turbines - were used for grinding grain by the 7th century AD, and were in wide use for this purpose and for pumping water by the Middle Ages; they were brought by the French to Canada in the 17th century and were commonly used for grinding grain.

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 in turn spins other blades, which are attached to generators that produce electricity.

The Persians are believed to have pioneered the use of windmills to pump water around 600 B.C. Grinding grain was another early use for the windmill in places like the Middle East, China and ancient Greece -- although there's no evidence that anyone outside of …

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 …

2. Wind energy The use of wind as an energy source begins in antiquity. Mankind was using the wind energy for sailing ships and grinding grain or pumping water. Windmills appear in Europe back in 12 th century. Between the end of nineteenth an d beginning of twentieth century, first electricity generation was carried out by windmills with 12 KW.

By the 10th century A.D., windmills with wind-catching surfaces as long as 16 feet and as high as 30 feet were grinding grain in the area now known as eastern Iran [Persia]and Afghanistan. The western world discovered the windmill much later. The earliest written references to working wind machines date from the 12th century.

Wind energy has been used historically for sailing boat, grinding grain and pumping water. Wind mills were used for harvesting energy from the wind, which developed overtime. Various new designs were constructed for obtaining maximum output. However, there is a limit for wind energy extraction as formulated by Albert Betz, with maximum theoretical efficiency of 59.3%.

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.

Before diving into the history of wind power it is important to understand the difference between a windmill and a wind turbine. A windmill is a device that uses the kinetic energy of the wind for mechanical work like grinding grains or pumping water, whereas a wind turbine uses the kinetic energy from the wind to produce electricity from a generator.

People used wind energy to propel boats along the Nile River as early as 5,000 BC. 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.
