Personally I'm glad we are using resources of our planet, in Europe they are everywhere, kinda like a signal to show they are being productive. I agree they can be an eyesore in the countryside, although in Europe there's a lot more land.
I believe the majority of the wind farms should be placed in the sea, just off our coasts. Again it will create a visual problem, but if placed stategically they shouldn't prove too much of an eyesore?
