If you’re trying to persuade your school district to rely on wind power, contact the good folks in the School District of Spirit Lake, Iowa. They’ll give you a detailed economic breakdown of the costs, and benefits, of their two wind turbines, with a total capacity of 1 MW. These turbines generate more than enough electricity for all of the District’s facilities. By the year 2008 their original investments will be paid off and the district expects to save about $140,000 each year thereafter.
