To find a smooth flow, Sagrillo recommends keeping the rotors at least 30 feet above anything within 500 feet. Another way to avoid turbulence is to site the turbine at least ten times as far away as the height of the tallest obstacles. Many parts of Wisconsin have good wind resources. In the Door County Peninsula, for instance, the average wind speed at 110 feet is 13 miles per hour, fast enough for utility-sized wind farms. Even Madison boasts average wind speeds of about 11 miles per hour.
Turbulence is the archenemy of wind power.
