I was told that one of the biggest costs of wind farms was the public inquiries that seem compulsory whenever one is proposed! This article was teh first in a Google search on 'WInd farm arguments fr and against' and seems to deliver a reasonable view. It includes the comment that since the 1980s the cost of energy production continues to deplete.

I think the need for wind farms will increase as we continue deforrestation though. It is a known fact that wind is created by trees waving their branches about - Have you ever seen a windy day when the trees are not waving their arms? We now have less trees so there is less wind and we have to mechanicaly produce it with wind farms. Just you watch - As the trees decrease the wind farms will spread. It is all part of the worldwide plot by the major powers so I suspect this post will not stay about long. Keep wearing the tinfoil hats...
