Wind Power or Wind Energy is the process by which wind is used to generate mechanical power or electricity. Wind turbines convert kinetic energy into mechanical power. They are available in a variety of different sizes. A generator then converts this mechanical power into electricity.
The wind turbines have massive propeller blades which turn in the air and power an electric generator. There are turbines with blades the size of a football pitch and they produce enough energy to power 1400 homes. A home sized machine normally has propellers between 8 and 25 feet and these are able supply all the needs of your home or a small business.
You often see a group of turbines together and this is often known as a wind farm. Electricity is generated in bulk and fed into a utility grid. Then just like conventional power plants it is distributed to customers.
Wind energy is clean, non-polluting and is a free renewable source of energy. Therefore it is great for the planet. However, the blades do make noise and there is a visual impact to the landscape. Also the blades can kill birds and bats.
Another negative is that using wind as a source of power is that it does not always blow when electricity is required. Also, good wind sites are often in remote places away from demand.
Although it can be a hefty investment wind power really could be an alternative for us all. As you travel through the British countryside they are more and more common. For example the photograph accompanying this post was taken in Brocton, Cannock, just outside the Seven Stars eatery https://thesevenstarsbrocton.co.uk/ (which I would highly recommend if you get the opportunity for a visit).
