Wind power or wind energy is the use of wind to provide mechanical power through wind turbines to turn electric generators for electrical power. 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. Onshore wind is an inexpensive source of electric power, competitive with, or in many places cheaper than, coal or gas plants. Onshore wind farms have a greater visual impact on the landscape than other power stations, as they need to be spread over more land and need to be built in rural areas, which can lead to "industrialization of the countryside"^{[better source needed]} and habitat loss.^{[undue weight? – discuss]} Offshore wind is steadier and stronger than on land and offshore farms have less visual impact, but construction and maintenance costs are significantly higher. Small onshore wind farms can feed some energy into the grid or provide power to isolated off-grid locations. (Full article...)

The San Gorgonio Pass wind farm in California, United States.

A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.

Many of the largest operational onshore wind farms are located in China, India, and the United States. For example, the largest wind farm in the world, Gansu Wind Farm in China had a capacity of over 6,000 MW by 2012, with a goal of 20,000 MW by 2020. As of December 2020, the 1218 MW Hornsea Wind Farm in the UK is the largest offshore wind farm in the world. Individual wind turbine designs continue to increase in power, resulting in fewer turbines being needed for the same total output. (Full article...)

This is a comprehensive list of onshore wind farms (more than 1 turbine) in the UK. 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...)

Windmill topics

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 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...)
