What is a wind turbine used for?

Wind turbines are the modern version of a windmill. Put simply, they use the power of the wind to create electricity. Large wind turbines are the most visible, but you can also buy a small wind turbine for individual use; for example to provide power to a caravan or boat. What is a wind farm? Wind farms are groups of wind turbines.

How do wind turbines work?

Wind turbines turn energy from the wind into electricity. Turbines turn so that they face into the wind. The turbine blades are shaped so that even low winds will push them round. Kinetic energy from the moving air is transferred to the spinning blades. The blades turn a shaft which is connected to a gearbox.

How much power does a wind turbine produce?

At a wind speed of 40–55 km/h (20–30 knots), it will produce a handsome 140–240 watts of power. At 20 km/h (10 knots), it produces a rather more modest 27 watts. If small is beautiful, micro-wind turbines—tiny power generators of about 50–150 W capacity, perched on a roof or mast—should be the most attractive form of renewable energy by far.
