In addition, there is currently no competitive market for wind energy (though there may be in the future), because wind is a freely available natural resource, most of which is untapped. [115] The main cost of small wind turbines is the purchase and installation process, which averages between $48,000 and $65,000 per installation.
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 ...
A wind farm or wind park, or wind power plant, [1] 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.
A wind farm says that it can produce 5 GW at £100 per megawatt hour (MWh). Then a big gas power plant promises to produce 4.9 GW at £110 per MWh. But there is still 0.1 GW needed.

The Vattenfall utility company study found Hydroelectric, nuclear stations and wind turbines to have far less greenhouse emissions than other sources studied.. A typical study of a wind farm's Life cycle assessment, when not connected to the electric grid, usually results in similar findings as the following 2006 analysis of 3 installations in the US Midwest, where the carbon dioxide (CO 2 ...
