How do wind turbines work?
** Wind turbines ** transform the kinetic energy of the wind into electrical energy. Figure 3 shows the key energy transformations that take place.





Have you ever seen a wind farm or a wind turbine? A ** wind turbine ** is rather like a giant fan. When the wind sets it spinning, it generates electricity. Wind turbines can range in size from small ones installed on large yachts and small buildings, to giant ones like those shown in Figures 1 and 2. A ** wind farm ** is a set of wind turbines that are linked together to supply electricity to a local community or to an electricity grid for a larger population. Many are located along coastlines where the winds are strong. The Woolnorth wind farm in Tasmania, shown in Figures 1 and 2, is an example of this.
