Wind energy uses the energy in the wind for practical purposes like generating electricity, charging batteries, pumping water, or grinding grain.

Turbines are perched on high towers, usually 100 feet or higher, and often placed in large groups, or "farms", to generate electricity to towns and cities.

On a much smaller scale, stand-alone turbines are sometimes used by farmers and homeowners to generate supplemental electricity.

In the past twenty years, U.S. government incentives in the form of tax credits to producers and incentives for homeowners have helped to lower the price of wind power by an estimated eighty-five percent, making it a more feasible option.

There are people who object to wind farms because of their appearance or the noise the turbines make. Wind power raises few other environmental problems except danger to birds.

There is also a problem with having a consistent generation of electricity with wind energy because of the of the unknown features of the weather. Sometimes the wind is simply non-active.
