Cost of wind power falls heavily in cases where a gas power plant and a wind power unit are acquired on identical terms.
Many residential customers think that converting to residential wind power will be hard or they will need to replace all the wiring in their home.
With an annual average growth of 32% between 1998 and 2000 wind power has become the fastest growing energy source in the world.
An average wind turbine has about two or three propeller blades, which are attached to a rotor.
Beyond any doubt wind power is the lowest cost type of renewable energy.
Wind power is now being touted as a highly efficient alternative energy source by many leading energy experts.
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.
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.
Interest in wind power is also growing in countries such as India and China, and Australia is paying increasing attention to the concept.
In most residential situations, a wind turbine is used as a supplemental source of power in combination with local, on-the-grid, utility power.
