SPIRIT LAKE, Iowa -- Towering more than 12 stories above a school playground, a pair of wind turbines(渦輪機(jī)) transform the usts blowing over the lakes and ridges sur-rounding this northern Iowa town into power that provides about half of the school district' s electrical needs.

     Students here can "look right out the back door" to see the giant turbines capture the wind and learn how they can produce power. More than 80 schools across the USA have installed some type of wind turbine, says Ian Baring - Could, senior engineer in a wind technology center at the National Renewable Energy Laboratory in Golden, Colo.

      Now, a program called Wind for Schools is aiming to bring smaller turbines to six states:Colorado, Idaho, Kansas, Montana, Nebraska and South Dakota. The program, sponsored by the U.S. Department of Energy' s Wind Powering America program at the National Renewable Energy Laboratory, is the first program to use smaller turbines with a mission of educating students and the cmmnunity about wind power.

      In Faith, S. D. , home to one of the schools hoping to build a small wind turbine in the next couple of years, a fierce wind blows across the plains most days. Angela King, who teaches science in grades 7 to 12 in Faith, believes a turbine wiI1 give students learning about wind energy the chance to "see it happening, rather than just reading it in a book. "

      Much of the first year of the three - year program has been spent identifying schools hoping to join the program. South Dakota, for instance, announced its eight school districts over the summer. About five schools in Kansas have the turbines, and schools in Montana, Idaho and South Dakota are now preparing sites and will have them installed during this school year.Now, the goal is to add wind turbines at about five schools per year in each state, for a total of about 30 per year overall, Baring - Gould says.
