I would agree with your sentiments in the case of a TV aerial or radio mast or a quarry, but when it comes to clean power I throw out all considerations. The planet and the environment come first. Plain and simple.
If the evidence of damage to the peat (itself only 3000 years old and a recent invader to these parts) was being damaged by turbines was strong enough then I would be against them, because the environmental damage caused <i>might</i> just outway the good they will do.
