They look it don't they? You should see the (once) windmill GRAVEYARD in east SF Bay Area - in a pass over to Livermore they built one of the first (and really huge) windmill farms - when I last saw it (1995?) more than 2/3 of the windmills weren't operational. What a waste! That pass gets a lotta wind . . . when it was operational it was really something to see.
