Use the wind to generate electricity has been around a long time - you've probably seen windmills on farms. When the wind turns the blades of a windmill, he turns a turbine in a small generator to produce electricity and a coal plant.
A windmill on a farm can make only a small amount of electricity - enough to power a few farm machinery. To make enough electricity to serve many people, power companies build "wind farms" with dozens of large wind turbines.
Wind farms are built in the flat, open areas where the wind blows at least 14 miles per hour. Iowa currently has more than 600 wind turbines producing enough electricity to power 140,000 homes. Minnesota and Wisconsin are also home wind turbine - and that number is growing daily.
Some schools in the Midwest have their own wind farms! In Spirit Lake, Iowa playground is just under two wind turbines.
