But as far as the new ones: I recently moved offices in Copenhagen, to a 5th-story office looking east towards the Øresund. I think the offshore wind farm there adds substantially to the view (http://en.wikipedia.org/wiki/Middelgrunden). It's especially nice on overcast, windy, gray days, when you can see the white turbines rotating in the fog. But it's nice on sunny days too, at least in my opinion. Here's a snapshot from my window: http://sphotos-b.xx.fbcdn.net/hphotos-snc7/598966_1010047304...

And if you get closer, e.g. at Amager Beach, it's even nicer (again imo). It's like a modernist kinetic sculpture or something, an aesthetically pleasing series of 20 massive but sleekly styled turbines in a row.
