Wind turbines harness the power of the wind and use it to generate electricity. When the wind blows, the blades are forced round, driving a turbine that generates electricity. The stronger the wind, the more electricity produced.
There are two types of domestic-sized wind turbine:
- pole mounted – these are free standing and are erected in a suitably exposed position, with generation capacity of about 5-6kW
- building mounted – these are smaller than mast mounted systems and can be installed on the roof of a home where there is a suitable wind resource. Often these are around 1-2kW in size
