Impacts

Impacts

Cape Wind: a 25-square-mile industrial scale wind power plant that would have consisted of 130 wind turbines, each 440 feet tall, and a 10-story electrical service platform housing 30,000 gallons of transformer oil. The turbines would have had 58 red perimeter lights which would flash in unison at night.

Cape Wind would have posed a major threat to the safety of air and sea travel in and around Nantucket Sound, devastated commercial fishing, desecrated a national treasure and sacred Tribal lands, threatened birds and marine mammals, and increased electric rates.

Environmental Impacts

Cape Wind would have posed threats and risks to the rich environment of Nantucket Sound during both construction and operations. A loss of habitat, changes in tidal currents, and harm or mortality to threatened and endangered avian and marine species would have likely resulted. Further, Cape Wind’s electrical service platform, which would have held 30,000 gallons of transformer oil, would have introduced the chance of an oil spill. Cape Wind’s own studies show that in the event of a spill, oil would reach the shoreline of the Cape and Islands in less than five hours. The project would have also disrupted commercial and recreational fishing in the resource-rich shoal area where Cape Wind would be situated.

Historic and Tribal Impacts

Cape Wind would have destroyed the tribal and historic values of Nantucket Sound. The local Wampanoag Tribes of Gayhead/Aquinnah and Mashpee believe Cape Wind would have not only desecrated sacred land, but also harmed their traditional religious and cultural practices. They are supported by the United Southern and Eastern Tribes, 25 federally-recognized Tribes. Wampanoag means “People of the First Light” and, as such, an unobstructed view of the sun rising over the Sound is integral to their way of life and traditions.

In addition, Cape Wind would have adversely impacted hundreds of historic properties dotting the Cape and Islands shorelines as well as several National Historic Landmarks, including the island of Nantucket. The federal Advisory Council on Historic Preservation recommended Cape Wind “be denied or relocated” because it would have a “permanent and devastating effect on the historic and cultural properties of the Sound.”

Economic Impacts

Based on its terminated contracts with National Grid and Eversource, Cape Wind would have added $3 billion in surcharges for Massachusetts ratepayers. Such rate increases would have led to job losses as businesses strove to offset these costs. These contracts have been canceled, due to Cape Wind’s failure to close on financing. Cape Wind would have also harmed the Cape and Islands economy by threatening tourism and commercial fishing and by lowering property values.

Public Safety Threats

Navigational safety – Cape Wind would have threatened the safety of millions of travelers crossing the Sound. The 130 turbines would have jeopardized navigational safety by creating obstructions that ferries, cargo ships, and pleasure craft would have to negotiate not only in clear weather, but in dense fog and highly variable weather conditions characteristic of the Sound. The spinning turbine blades would have also interfered with marine radar.

Aviation safety – Cape Wind would have also posed a significant risk to the 400,000 flights and millions of passengers that traverse Nantucket Sound every year due to radar interference and its location in the center of three airports. It would have also impacted search and rescue efforts.

Cape Wind’s 130 wind turbines, each 440 feet tall, would have been highly visible from the south shore of Cape Cod from Falmouth to Chatham, the eastern shore of Martha’s Vineyard from Vineyard Haven to Edgartown and Cape Pogue, and the northern shore of Nantucket from Wauwinet to Madaket. With hundreds of fixed and flashing navigational and aviation lights, the turbines would have urbanized the night-time sky.

Q&A with Audra Parker, President & CEO

Together, we have made great strides in our mission to permanently protect Nantucket Sound. But, we need your continued support to leave a lasting legacy for our children and grandchildren. I encourage you to contribute to our preservation campaign. Nantucket Sound won’t stay a national treasure without your support.

Why is Nantucket Sound a national treasure? The Sound has a rich tribal and maritime history and has long been recognized as more than just a body of water. It is the heart and soul of the Cape and Islands. It is a significant marine habitat for a diversity of ecologically and economically important species. It provides a livelihood for local fishermen, an inspiration for artists, and is a source of solace, relaxation, and recreation for the millions that flock to its shores. Nantucket Sound connects all of us who live and visit here.

Why is Nantucket Sound still vulnerable to industrialization? While the state waters of the Sound are protected under Massachusetts law, the federal waters in the center remain open to industrial development.

How can we permanently protect Nantucket Sound? The best way to secure permanent protection for the Sound is through federal legislation. The Alliance has proposed the ‘Nantucket Sound National Historic Landmark Act’ which would recognize the Sound’s historic, environmental and economic values. It would also prevent future development by prohibiting industrial projects in the Sound.

What have we achieved since the defeat of Cape Wind? We made solid progress toward enacting this federal legislation. We worked closely with our federal delegation and built a strong and diverse coalition of support. We earned endorsements from Governor Baker, our local representatives and nearly 100 key stakeholder groups. This coalition of elected officials, environmental groups, municipalities, tribal governments, historic preservation groups, commercial fishermen, and many others, is urging our representatives in Washington, D.C. to enact the Nantucket Sound National Historic Landmark Act.

Why does the Alliance still need funding? The Alliance is the only group that is fighting to protect Nantucket Sound. As a non-profit, we rely solely on private donations. Thank you for your continued generosity as we work to Save Our Sound… FOREVER. Your tax-deductible donation today will leave a legacy for tomorrow.
