The project has been the subject of resistance for years from some local organizations concerned it will threaten the wildlife and aesthetics of Nantucket Sound. Some local residents and environmental groups also fear it will decrease property values and significantly disrupt the habitats of several local animal species.
The late Sen. Edward Kennedy M. Kennedy opposed the project.
Supporters of the project say the wind farm will significantly reduce oil consumption with clean energy and provide a substantial supply of electricity to New England.
The massive project is to be built by a private developer, Cape Wind Associates. It is expected to cost over $800 million, according to the Cape Cod Times.
