The cape wind project intends to install dozens of wind towers off Cape Cod. This project has drawn a ridiculous storm of criticism with "Not In My Back Yard" (NIMBY) style protests from people who normally support ecological initiatives, but call this a blight. er... The huge cities are ecological blights, but how are wind towers a blight?
Alaskan Senator Threatens to Halt Cape Wind Project discusses a proposed ammendment by Alaska Congressman Don Young which would change the buffer requirements around offshore wind tower projects. There's more details in the article, the gist being that the current standard is a 500 foot zone around each wind tower and any shipping lanes. Further the current standard has the Coast Guard reviewing these plans. The proposal arbitrarily sets a 1.5 mile buffer zone, and removes the Coast Guard from review.
Fortunately this is only a proposal to put an ammendment on in committee. But it's a dangerous sort of thinking that's clearly intended to scuttle offshore wind projects.
