The scientific community does seem to be rethinking the environmental impact of wind energy at this point. Supposedly the drag created by windmills is enormous for the amount of energy they provide, so in order to take up a greater portion of our current energy needs, it would drastically harm the environment from essentially slowing down the wind. Local temperatures rise substantially, but there's meteorological effects beyond that that are not fully understood at this time. Here's a primer article on what's been found. http://www.seas.harvard.edu/news/2013/02/rethinking-wind-power http://www.seas.harvard.edu/news/2013/02/rethinking-wind-pow...
