The Federal Aviation Administration says five wind turbines can't be built at the Massachusetts Military Reservation on Cape Cod, six days after approving them. The FAA now says the 400-foot high turbines pose a hazard to air navigation.

Construction on Berkshire Wind's $46 million wind turbine project atop Brodie Mountain has been halted indefinitely because of a dispute over its access road. Silverleaf Resorts Inc., which plans a $42 million vacation condominium project at the foot of Brodie Mountain, contends Berkshire Wind's 2004 road permit had expired because it took more than a year -- the life of the permit -- for "substantial construction" to begin, according to the injunction order issued last week by the Massachusetts Land Court in Boston.

Construction of 10 wind turbines along Brodie Mountain has stopped after Massachusetts Land Court issued a temporary injunction against Berkshire Wind Power Cooperative Corp. late last week. The injunction, obtained by abutter Silverleaf Resorts Inc. as part of a pending lawsuit, prevents Berkshire Wind from using part of a road that crosses private property in Lanesborough leading up to the site of the project. Tyler Fairbank, chief executive officer of EOS Ventures, Berkshire Wind's communications and public relations firm, said Tuesday that the injunction is temporary while a Land Court judge reviews a suit filed by Silverleaf about the validity of a special permit for the access road.

History may judge Cape Cod renewable-energy initiatives sooner than many expected. Although the proposed Nantucket Sound wind farm is the most prominent example of conflict between history and renewable-energy efforts, less well-known projects face scrutiny from historic preservation advocates across the Cape.

The Massachusetts National Guard took a giant leap toward generating its future electricity needs through wind this week with about half of its proposed turbines approved by the Federal Aviation Administration without restrictions. The FAA approved eight of 17 sites at the Upper Cape military base on Thursday, saying they pose no adverse effects to aviation.

There are only 14 articles on the warrant for the Oct. 26 Wellfleet Special Town Meeting, but four of them are big ticket items, expected to generate a lot of discussion. Chief among them is article 2, which asks voters to appropriate $290,000 for the permitting and survey of the building site for construction of one wind turbine at Wellfleet-by-the Sea.

The Martha's Vineyard Commission (MVC) last Thursday voted 12 to 1 to accept a nomination to create an Island wind district of critical planning concern (DCPC) that would cover the airspace above 220 feet over the waters of Dukes County. The purpose of the DCPC is to provide a framework to regulate large-scale wind turbine development, according to the MVC. ...Acceptance of a nomination immediately triggers a moratorium on development permits.

Final approval for Cape Wind is stalled, aggravating developers of the Massachusetts offshore wind project and igniting concerns that the latest roadblock -- over American Indian ceremonies -- could jeopardize other ocean-based energy proposals. ..."There's great concern. It should have been finished months ago," said Mark Rodgers, a spokesman for Cape Wind, noting that the delay is disrupting efforts to arrange construction contracts, line up installation barges and find buyers for the anticipated electricity.

The city announced yesterday it is one of 103 Massachusetts cities and towns to receive a planning assistance grant from the Green Communities Program from state Department of Energy Resources. The grant will help communities like Newburyport take the necessary steps to becoming official Green Communities by providing free technical assistance to reach a set of pre-written standards.

The West Roxbury Neighborhood Council supported the placement of a temporary 200-foot meteorological tower at a site on the Roxbury Latin school campus Monday night ...Discussion was heated among residents in attendance, with both supporters and challengers to the proposal voicing their opinions. Ultimately, however, the 6-2 vote in favor of the MET tower left many residents at the meeting feeling their thoughts on the matter were not seriously considered by the board.

The discovery of wetlands on the Chase Road site where two wind turbines are proposed means the project has to be temporarily placed on hold, proponents said Monday night. Word came the same night that an estimated 75 opponents came out in protest of the $9.5 million project, targeted for the 137-acre Chase Road site.

In the scramble to harness ocean wind power, floating turbine technology may be the holy grail. Turbines that can be floated into position and anchored in deeper water are the solution to much of the politics that confronts shallow-water projects, according to proponents of the concept. A pair of announcements this month seems to herald the next step into deeper water.

Starting on Monday, travelers in northern Berkshire County will be sharing the road with giant pieces of 10 wind turbines that will be transported to Brodie Mountain for the construction of the $46 million Berkshire Wind Project. Transporting the wind turbine parts is expected to take three weeks. ...Connection to the grid and the start-up of power generation is anticipated to take place in the spring.

Trucks carrying wind turbine components bound for the ridge line of Brodie Mountain will join traffic along Routes 43, 7 and Brodie Mountain Road beginning next week. Acting as spokeswoman for the Berkshire Wind Project, Betsy Strickler of EOS Ventures -- a renewable energy company, said Thursday project equipment will begin moving on Monday from Stephentown, N.Y.

A question of jurisdiction from the Old King's Highway committee has halted preparation work for Cape Cod Community College's 380-foot wind turbine project. The Barnstable Old King's Highway Historic District Committee believes the project requires a certificate of appropriateness in order to proceed. The entire college campus falls within the historic district, which extends from Route 6 northward. ...In an e-mail, college director of communications Michael Gross confirmed that the project is stopped.

Well over 100 people attended the public hearing called to receive feedback on the Oceans Management Plan, billed by the state government as a first-in-the-nation attempt to manage all development in Massachusetts waters. But just one issue dominated proceedings: wind generation. ...Overwhelmingly, the dozens who rose to speak were opposed to the plan, either outright or in part - although most also asserted their support in principle for alternative power generation.

Although the public hearing was the fifth and last in the comment phase of the state's process, state officials said they would plan to come back for further less formal discussions with Islanders. The public comment period for the draft plan ends November 23. "We would like to say to the governor, yes we can, but it's ‘we' - you have to come and talk to us," Dukes County manager Russell Smith said.

The Air Force has scrapped a ribbon-cutting ceremony scheduled to celebrate its new 1.5-megawatt wind turbine while it waits for essential parts sitting in a New York port, a spokesman said yesterday. ...It's unclear when the Air Force will be able to move the parts to Massachusetts, he said, so the celebration and turbine are on hold indefinitely.

Developers of a proposed 331-foot-tall wind turbine to generate electricity for the Berkshire East Ski Resort answered Planning Board questions regarding the turbine's impact on nearby wildlife and houses.

It's one step in what will be a lengthy process, but the Massachusetts Renewable Energy Trust will be undertaking a site assessment of several possible locations in Duxbury for the placement of a wind turbine. Emily Dahl, a spokesperson for the trust, said DNV Global Energy Concepts, a company with offices in Lowell, would be performing what she called a "desktop analysis".
