But one of the biggest, perhaps THE biggest problem currently facing the Great Lakes is the dangerous level of mercury in the waters (we're told not to eat fish from them, and "dead zones" are appearing in areas), a result of the pollution from coal-fired electricity generation.  

Would windfarms be able to replace some of these plants, decreasing the pollution and restoring the ecosphere of the lakes?  Seems like that would be a serious incentive.
