I think they are very expensive and they don't generate the electricity that the left tell everyone that they do. I saw a documentary on the news about them when that snowstorm hit Texas and that's how I found out about the parts not being recycled or reused for anything. The center that holds the blades were laying on the ground at the bottom of the windmill where someone had changed them out but left the part laying. I have no idea why they can not be recycled; especially as expensive as they are.
