Smitty, I double checked this. Apparently it’s totally inaccurate and the authors words have been selectively quoted (or misquoted) to make windmills look less effective than they actually are. It’s based on the premise that windmills are placed in poor locations where in reality they’d most likely never be built.
They are ugly though, I’ll give you that.
If you look at Homer-Dixon.com the supposed author suggests the poster is fraudulent and that he didn’t write that.
