What are wind turbines and how do they work?
Wind turbines are the most common of the alternative energies, they are effectively the modern equivalent of the old fashioned windmill. The rotors or blades of the wind turbines are placed on a pole high up, where they need relatively little wind to turn them. The spinning blades of the turbines create electricity by rotating a permanent magnet to generate electricity, which can be used for a variety of purposes. The more electricity required the bigger the wind turbines required. When most people think of wind turbines they think of the very large commercial wind farms, with very high, very large wind turbines. Wind turbines are now available on a much smaller scale for domestic dwellings, and are capable of generating sufficient electricity for the household, and dependent upon size, there is also the possibility of selling excess electricity to the grid.
