This can vary greatly on the type of windmill... I live near the Altamont wind farm, and the oldest windmills are undeniably ugly, and so small that they required tons of them. The next generation windmills were less ugly, but still too small. I always found them rather unobjectionable, but I could see one quibbling with that. The current giants being put up though? They look great! They have these 90 foot blades that look like they were designed by an advanced alien race, their size makes them operate with a slow graceful sweep, and the relatively low density of them leaves the hillsides more visible as well.
