Using wind as a variable resource
Wind has been utilized for hundreds of years to perform many functions for man. From pumping water to making flour, wind mills have been making life easier for mankind by using the power of the wind and a little old fashioned ingenuity. Wind can be a great renewable resource option if the right conditions are available to you. For the most part wind is not reliable enough to rely on as your only source of power unless you have a very large turbine(s) and battery bank for those days when wind is not as abundant.
How Does a Wind Turbine Work?
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of faster and less turbulent wind. Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electricity grid (shown here) for more widespread electricity distribution.
