The devices that generate mechanical energy from wind power resources are called wind mills.
Residential wind power systems are closer than some might think to becoming a widespread reality. Already many homeowners all over the world are using wind generators to produce 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.
Homeowners today everywhere are even turning towards wind power, it is said that you can save up to 50 - 90% in energy this is also depending on the amount of wind and also the wind turbine size.
Solar radiations emit a type of energy, which result in creation of wind.
In most residential situations, a wind turbine is used as a supplemental source of power in combination with local, on-the-grid, utility power.
Wind power is abundant in many parts of the world which can be used safely to generate electricity.
Beyond any doubt wind power is the lowest cost type of renewable energy.
If your home uses 10,000 kWh (kilowatt-hours) of electricity each year, a small turbine of rating between five and fifteen kilowatts should be sufficient for your needs.
Aside from the manufacturing process, wind power emits absolutely no greenhouse gases.
