A grid-tie wind system may be as simple as a wind turbine and a Xantrex grid-tie inverter. Depending on the amount of power being used by the household, electricity is either fed to or accepted from the utility.
The wind turbine is placed on a tower at a height of up to 100 feet where the rotor blades are exposed to faster and less turbulent wind. This enables the turbine to produce the maximum amount of power. Usually, two or three blades are mounted on a shaft connected to the turbine to form a rotor.
Wind blowing over the blades causes them to lift and rotate. This rotation is used to spin a shaft inside a generator that converts the motion into electricity for use in the house or business.
Wind is a completely renewable fuel source and produces no health risks and no air pollution.
