Wind has been used as an energy source from last several decades. The Babylonians and Chinese had used wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were about long before that. Wind power was used during the middle Ages, in Europe, to grind corn, which is where the phrase "windmill" comes from.

The Sun heats our atmosphere disproportionately, so some places become warmer than others. These warm patches of air rises, other air flows in to replace it and we feel a wind blowing. Thus we can use the energy in the wind by building a giant tower, with a large propeller on the top. The wind blows the propeller on all sides which turns a generator to produce electricity. The rotation of propeller turns wind generator thus generating electricity. A grid tied wind turbine is a rotating engine which converts the kinetic energy of wind into mechanical energy. If the mechanical energy is as a substitute converted to electricity, the machine is called a wind generator, wind turbine, wind power unit (WPU), wind energy converter (WEC), or aero generator.
Another way is to use Inverters and power panels. Solar energy is the most readily obtainable source of energy. It does not belong to anyone and is, therefore, free. Solar energy has been used since ancient times, but in a most primordial manner. Before 1970, some research and development was carried out in a small number of countries to exploit solar energy more efficiently, but most of this work remained largely academic. Solar Panel inverters are used principally to change direct current (DC) to alternating current via an electrical switching process. You can suppose of inverters used with solar panels as electronically synthesized alternators. Solar panels are used convert solar energy to electrical energy.
If you live in an area where there is a substantial amount of wind, get one of these systems and get free electricity. Call hardy solar at 800-341-7027 for a free consultation.
