Wind power generators are machines that convert wind energy to electrical power. The only required fuel is wind and is therefore free, natural and unlimited.
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.
Technological advances make it more and more feasible to install wind power generators for individual homes.
Off grid wind power systems often cost about 30% more than on-grid systems.
In a typical residence that uses under 10,000 kilowatt hours per year of electric power, a 5-15 kilowatt wind turbine should more than suffice.
Using wind power holds out many added advantages, including significant reduction in electric charges, stopping any unnecessary wastage of power, and helping to sustain the environmental balance by ensuring zero pollution of the atmosphere.
The wind power information that our ancestors knew has helped them create a wind power system that could work on irrigation and furnaces. By 7th century the very first wind mill was made in Afghanistan.
With an annual average growth of 32% between 1998 and 2000 wind power has become the fastest growing energy source in the world.
Industries of different types all over the world have started to utilize wind power.
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.
