WIND POWERWIND POWER
Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships. Individual-wind power units may be purchase to reduce or eliminate the dependence on grid electricity.
A wind turbine is a rotary device that extracts energy from the wind. If the mechanical energy is used directly by machinery, such as for pumping water, cutting lumber or grinding stones, the machine is called a windmill. Wind turbines have been used for household electricity generation in conjunction with battery storage over many decades in remote areas. |
