On Grid Wind System

 A grid-tie wind system consists simply of a wind turbine and a grid-tie inverter. The wind turbine is placed on a tower 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 to form a rotor. Wind blowing over the blades causes them to rotate. This rotation is used tospin a shaft inside a generator that converts the kinetic energy into electrical energy that feeds the load. If the load is less than the energy production the excess goes through the  grid.
Wind is a completely renewable fuel source and produces no health risks and no air pollution
