Wind turbine design is the process of defining the form and configuration of a wind turbine to extract energy from the wind. [1] An installation consists of the systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power , and other systems to start, stop, and control the turbine.
The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site. A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps, wind turbines, and other applications.
It is a rudimentary and inefficient type of windmill [1]. That is, a panemone primarily uses drag whereas the blades of a HAWT use lift. [1] Historically the earliest known wind machine was made by the Persians and it was the panemone design, consisting of a wall, with slits, surrounding a vertical axle containing four to eight fabric sails.

Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. [181] A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power , and other systems to start ...
Around the time of World War I, American windmill makers were producing 100,000 farm windmills each year, mostly for water-pumping. [15] By the 1930s, use of wind turbines in rural areas was declining as the distribution system extended to those areas. [16] A forerunner of modern horizontal-axis wind generators was in service at Yalta, USSR, in ...
Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.
The use of windmills became widespread across the Middle East and Central Asia, and later spread to China and India. [22] Vertical windmills were later used extensively in Northwestern Europe to grind flour beginning in the 1180s, and many examples still exist. [23] By 500 AD, windmills were used to pump seawater for salt-making in China and ...
