We got our first wind farm on Maui last year. They're arrayed along a ridge that can be seen from the south part of the island. After they were finished a number of letters were printed in the local paper screaming about the visual pollution. The ridge is made up of volcanic rock, brown grass and mangy looking trees. Visual pollution indeed!

One letter writer demand they be painted to blend into the dead grass. The reason they're painted white is to keep from killing the birds.

The only downside I can see is they only generate power when the wind blows so the power company can't rely on them. That means they still have to buy and maintain diesel generators. Luckily we have consistant winds for most of the year.
