At 2640 feet, noise from an industrial wind turbine may still be heard from inside your home... 1/4Mile may not be far enough.
A minimum setback of 2640 feet from a home is necessary to mitigate the noise impacts that aren’t predicted by the one-size-fits-all sound models typically used by wind developers. Noise may be amplified by the lay of the land, atmospheric conditions, time of day, temperature inversions, wind layers and other factors. Low frequency noise can travel much further and easily penetrates the walls of a home.
Distance is the only thing which reliably lessens the negative effects of turbine noise. At 2640 feet, noise from an industrial wind turbine may still be heard from inside your home, but will be less of a problem than the noise from a turbine sited 1000 feet from your home. Residents whose homes are less than 2640 feet from large wind turbines have complained of trouble living with the noise they make, especially at night, and suffer from the variety of health effects associated with loss of sleep.
Recent studies show that a setback of 2640 feet will significantly reduce noise annoyance and associated adverse health effects, but even at that setback people may still suffer from problems associated with turbine noise, especially in quiet, rural environments. A setback of 5280 feet has been shown to eliminate most noise complaints. Both Germany and France have a setback of a mile.
http://betterplan.squarespace.com/todays-special/2008/12/11/121208-part-3-of-our-look-at-the-history-and-content-of-the.htmlI would like to see the specifics of the bill. There are many smaller turbines out on the market and I 'd be curious to see if there are restrictions on those.
But I'll wager dollars to doughnuts the restrictions are more favorable then not for major power companies like WE Energies.
