What’s wind power? Wind turbines convert the kinetic energy from the wind into mechanical energy which is then used to drive a generator that converts this energy into electricity. The UK has more usable wind power than any other European country and large scale wind turbine farms on and offshore will become a major supplier of electricity to the national grid in the next twenty years. As at 15 Mar 2010, there are 245 UK grid- connected wind farms containing 254 wind turbines with the capacity to generate 4113 MW. Source: BWEA
What kind of wind turbine? Horizontal axis turbines (HAWT) are the more familiar ‘windmill’ type. Vertical axis turbines (VAWT) known as ‘eggbeater’ turbines required a power source to start rotating because of their high torque.
Benefits Wind is free, wind farms need no fuel. Produces no waste or greenhouse gases. The land beneath can usually still be used for farming. Wind farms can be tourist attractions. A good method of supplying energy to remote areas.
