Wind Farms in North Dakota

Hear hear. I'm a North Dakota native (now living in Fargo) and visited the wind farm near Edgeley about a year ago and took my camera with me. Some environmental people complain that the generators are ugly and that they kill birds. First, I think they look beautiful and secondly, if you've lived on a farm in a house that had a window, I'll tell you right now that a window poses much more of a "bird killing risk" than any wind farms do. North Dakota is one of the few places in America where there is always a wind (it is almost never calm here). Why not harness this naturaly occuring energy source? I can't think of a valid reason not to.
