The proposal is to test whether there is enough wind to establish windmills 2 kilometers out into the lake. That is considerable distance from the bluffs and will not have a big impact on how they look. Also most people find the curve of white windmills an attractive feature in the places where they have been located. Finally, the threat of global warming will do the bluffs a lot more harm than the wind power that will help to prevent it.
