An environmentally friendly power generation source, the windmills are usually set-up in areas of high speed, constant winds. These wind power offers advanced-technology products that let homeowners and businesses generate their own clean power. These turbines are also used for off-grid homes, for rural electrification, and to boost the performance of solar electric systems. They generate electric power and feed the battery source when the blades turn. There are small generators at the base of the blades that turn mechanical energy into electrical energy. Wind generators can be used alone, or they may be used as part of a hybrid system. Hybrid systems are especially useful for winter backup of home systems where cloudy weather and windy conditions occur simultaneously. To get the most out of the wind you need to have your machine up in clear air. The higher your wind generator is the less it will be negatively affected by turbulent wind and the more power it will produce.
