A major concern with on-shore wind turbines is bird strikes. An article in the May Readers Digest says that an on-shore wind farm in Smola, Norway in a 9 year study has found a 70% reduction in bird strikes by painting one of the three blades black. This "motion smear" allows birds to see the blades. Seems this could save mega bucks by eliminating miles and miles of underwater cable. I would rather see turbines along the GSP in non-residental stretches than in the ocean, and with much less environmental impact.
