Wind farms 

A wind farm is a group of wind turbines in the same location used to produce energy. You can get offshore wind turbines as well as onshore. A large wind farm may consist of several hundred or more wind turbines therefore generating a lot of energy.
Wind farms tend to be located in rather hilly, mountainous areas. This is usually because there is more wind higher up which is useful for more wind power to be generated.
Wind is a renewable energy resource and there are no fuel costs. No harmful polluting gases are produced.
