Keep in mind these people are living with 20 turbines (not 70 or more) that are located at least 2500 feet away from their homes (not the 1,000 feet proposed in Champaign County).
Safe setbacks: How far should wind turbines be from homes? Let's start with what one manufacturer considers to be safe for its workers. The safety regulations for the Vestas V90, with a 300-ft rotor span and a total height of 410 feet, tell operators and technicians to stay 1,300 feet from an operating turbine -- over 3 times its total height -- unless absolutely necessary. That already is a much greater distance than many regulations currently require as a minimum distance between wind turbines and homes, and it is concerned only with safety, not with noise, shadow flicker, or visual intrusion. In February 2008, a 10-year-old Vestas turbine with a total height of less than 200 feet broke apart in a storm. Large pieces of the blades flew as far as 500 meters (1,640 feet) -- more than 8 times its total height. The Fuhrländer turbine planned for Barrington, R.I., is 328 feet tall with a rotor diameter of 77 meters, or just over 250 feet (sweeping more than an acre of vertical air spa...
