A drawback to wind power is that the wind can be erratic, changing direction by the hour.
Wind power is competitive and has provided good value in wholesale power markets.
Wind power is best described as the conversion of wind energy into a usual form, for example electricity.
The theory behind the wind power generator is simple. For windmills, the wind rotates the rotor blades to operate a pump or other mechanical systems.
Research from a wide variety of sources in various countries shows that support for wind power is consistently between 70 and 80 per cent amongst the general public.
Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator.
Interest in wind power is also growing in countries such as India and China, and Australia is paying increasing attention to the concept.
Cost reductions, technology improvements and government incentives are all responsible to the rapid growth of wind power.
Any home owner may very easily build a small wind turbine, or a number of them, to generate all or part of their required power.
The devices that generate mechanical energy from wind power resources are called wind mills.
