What a difficult question - it is almost heresy to say that you do not support a green energy initiative. But.....our local village school put up a wind turbine, which does provide their energy (and they sell back to the grid) and many of the villagers are very unhappy about it - it truly is astonishingly noisy on windy days - it really is like a helicopter landing. I would not like to be living near it - we are lucky to be far enough away not to hear it.
I am not a scientist and do not know what the answer is, but it would be good to find one that might not be such a blight.
Having said that I do not find turbines particularly ugly, but then I only drive past them and am unlikely to finish up with one in my backyard.
