Wind A wind system uses the force of the wind to turn a windmill which turns a generator thus producing power. In order for this system to produce power, you need to have a wind speed of 10- 12 mph. Note that this is just to begin producing power- just because it is turning does not mean that anything useful is being produced... To produce any kind of significant power on a sustained basis, you need to have an average wind speed of at least 25 mph. Few places in Missouri have this kind of wind. See the wind map as an example.
Wind systems come in all shapes and sizes. Some are the traditional pole mounted propeller type. Others spin horizontally. Because of the movement involved in a wind system, parts will wear over time and the maintenance will be greater than that required by a solar system. Additionally, harmonic vibration is common (depending on the rotational speed), so installing a wind generator away from a house, or houses, is recommended. Finally, the height of installation is critical. The ideal wind system will have 360 degree access to clear air. Trees, buildings, hills and other structures can all cause wind turbulence which will lessen the amount of wind actually reaching the generator’s blades.
