Wind power or wind energy is mostly the use of wind turbines to generate electricity. Historically, wind power has been used in sails, windmills and windpumps. Wind power is a popular, sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network.

In 2020, wind supplied almost 1600 TWh of electricity, which was over 5% of worldwide electrical generation and about 2% of energy consumption. With over 100 GW added during 2020, mostly in China, global installed wind power capacity reached more than 730 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...)

Whitelee Wind Farm is a windfarm on the Eaglesham moor in Scotland. The main visitor centre is located in East Renfrewshire, but the majority of turbines are located in East Ayrshire and South Lanarkshire. It is the largest on-shore wind farm in the United Kingdom (second in Europe to Fântânele-Cogealac, in Romania) with 215 Siemens and Alstom wind turbines and a total capacity of 539 megawatts (MW), with the average of 2.5 MW per turbine. Whitelee was developed and is operated by ScottishPower Renewables, which is part of the Spanish company Iberdrola.

The Scottish government had a target of generating 31% of Scotland's electricity from renewable energy by 2011 and 100% by 2020. The majority of this is likely to come from wind power. (Full article...)

This information is gathered from multiple Internet sources, primarily the UK Wind Energy Database from RenewableUK (formerly BWEA) and The Wind Power's database,  and is current up to October 2010. The name of the wind farm is the name used by the energy company when referring to the farm and is usually related to the name of the physical location. E.g. hill, moor, fell, down etc. or the name of the agricultural farm for the smaller installations on property owned by farmers. The "wind farm" part is implied and hence removed for clarity in most cases. (Full article...)

They were listed on the National Register of Historic Places in 1983; the listing included two contributing buildings on 1.3 acres (0.53 ha).The water tank is round, constructed of rock walls about 12 feet (3.7 m) tall and 14 feet (4.3 m) in diameter.  It is covered by a concrete-coated wood plank cover.  It is one of Bill Darrah's earlier water tank works, and was built for his brother Ben Darrah's upper ranch. (Full article...)

A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines and other applications. The term wind engine is sometimes used to describe such devices. (Full article...)
