Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid.

In 2022, wind supplied over 2000 TWh of electricity, which was over 7% of world electricity and about 2% of world energy. With about 100 GW added during 2021, mostly in China and the United States, global installed wind power capacity exceeded 800 GW. To help meet the Paris Agreement goals to limit climate change, analysts say it should expand much faster - by over 1% of electricity generation per year. (Full article...)

The Chokecherry and Sierra Madre Wind Energy Project is large-scale wind farm located near Rawlins, Wyoming, currently under construction. If completed as scheduled in 2026, it is expected to become the largest wind farm in the United States and one of the largest in the world. Located largely on federal lands, the project is being built in conjunction with the TransWest Express transmission line to supply power to the California market. Originally slated for completion in 2020, the goal was extended to 2026 in 2019 amid permitting, environmental, and construction delays. (Full article...)

A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (gristmills), but in some parts of the English-speaking world the term has also been extended to encompass windpumps, wind turbines, and other applications. The term wind engine is also sometimes used to describe such devices. (Full article...)
