  2. Wind turbine - Wikipedia

    en.wikipedia.org/wiki/Wind_turbine

    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]

    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.

    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.
