Issues of icing, noise, and structural damage and failure, particularly as they determine setback requirements, have been extensively documented by John Mollica in response to proposed expansion of the wind facility on Wachusetts Mountain in north central Massachusetts (between Princeton and Fitchburg). The title of this post links to a page from which a complete or partial PDFs can be downloaded.
What sets this paper apart is that it relies solely on information from wind industry proponents. The Wachusetts project borders a public recreation area, and Mollica shows that the proposed expansion doesn't come close to meeting even the industry's own guidelines for safety and nuisance setbacks.
