Most are in places where the wind is strongest, such as Wales, Scotland and Cornwall. Look at the map to see where some of the main wind farms are. Already, UK wind farms make enough electricity for many thousands of homes. Other wind turbines are very small. They can be used in a number of ways - by houses with no other electricity, on boats and so on.
Wind energy is one of the most popular renewable energy technologies.
Just over eight out of ten people are in favour of wind energy. Wind energy is very safe. No member of the public has been injured by wind energy or wind turbines anywhere in the world. In March 1999 Cassop School in County Durham became the first school in Britain to be powered by a wind turbine. The school is even able to sell some electricity to the grid.
