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.
In 2023, 421.1 terawatt-hours were generated by wind power, or 10.07% of electricity in the United States. [4] The average wind turbine generates enough electricity in 46 minutes to power the average American home for one month. [5] In 2019, wind power surpassed hydroelectric power as the largest renewable energy source in the U.S.
Offshore wind power currently has a share of about 10% of new installations. [8] Wind power is one of the lowest-cost electricity sources per unit of energy produced. In many locations, new onshore wind farms are cheaper than new coal or gas plants. [9] Regions in the higher northern and southern latitudes have the highest potential for wind ...
Wind Power Density (WPD) is a quantitative measure of wind energy available at any location. It is the mean annual power available per square meter of swept area of a turbine, and is calculated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density. [25]

India has the fifth largest installed wind power capacity in the world. [96] As of 31 March 2014, the installed capacity of wind power was 21136.3 MW mainly spread across Tamil Nadu state (7253 MW). [97] [98] Wind power accounts nearly 8.5% of India's total installed power generation capacity, and it generates 1.6% of the country's power.

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.
