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...
