Wind Power

• The force of moving air.• Can be captured by a windmill, which can

be used to generate electricity.• The amount of power generated depends

on the speed of the wind, the length of the windmill’s blades, and efficiency of the windmill.

Windmill Farms

• For wind to provide for several homes, windmill farms must be built.

• Windmill farms can have up to several hundred windmill’s.

• Farms in the U.S. – Hawaii, California, New Hampshire.

• Homeowners can use individual windmills to power small electrical generators.

Windmills over the years• Wind isn’t the most efficient way to provide

electricity.• Since 1991, the number of windmills dropped in

California. - The amount of electricity has remained about

the same.• 1999, California windmills produced over 1650

megawatts of electricity - About the same amount produced by a

medium sized nuclear powerplant.
