Wind farms are an incredible waste of money.Probably the absolute most expensive method of producing electricity devised.Small scale onsite wind plants fit niche needs due to transportation costs of fuel and so on and make economic sense in those special cases.
A little side bar re your great photo. If that guy, you, I or even a native American took 1 feather from that dead eagle, we could go to jail and get a big fine. Apparently, it is okay for the wind farms to slaughter eagles and other protective birds, but illegal to take a single feather.
