The most effective argument against windfarms is the aesthetic one- the presence of a windfarm will ruin the view. The danger for us is that this is true- a windfarm is an intrusion into a natural landscape. So we need to change the frame, because the choice is not between nature and windfarms, the choice is between windfarms and coal-fired electric plants.

Windmills are prettier than smokestacks.

This frame is the genuine choice at hand, and that sentance has a clear winner built into it. No way a smokestack (the word implies smoke) can be nicer than a windmill (think bucolic scene from the Netherlands of windmills, tulips and open fields).

Please consider using this in all discussions of wind power. Thanks for the starting point Jerome.
