Wind energy has been harnessed in various ways over thousands of years, from sailing ships to traditional windmills. A modern wind turbine works on the same basic principle as these windmills, using the wind's power to turn its blades, which in turn powers mechanical equipment that produces electricity. Here we look at wind energy, how wind turbines work, and the factors that need to be considered in their installation.
