I agree that over regulation is problematic, but to suggest that wind farms should be allowed to compete in an 'open market' ignores the fact they are given extremely favorable treatment (often ignoring laws such as E.S.A. or voltage regulations for the grid) and are the most heavily subsidized energy form. When allowed to compete in more level arenas wind farms (both on or off shore) fail miserably. With respect to shipping lanes--if the wind farm imposes safety risks on shipping the wind farm should compensate shippers.
