I think one problem is the people designing wind turbines are too hooked on the idea that things have to be shiny and modern looking. I've no doubt that it'd be possible without much trouble, and without losing efficiency, to vary the way they looked, in ways that would make them much more appealing to people who don't much like shiny and modern looking.

Of course the people who do like shiny and modern would probably object to that. But there's no reason they all have to look the same. After all, the old windmills came in all kinds of different shapes and sizes and design.
