Over the next several months Stantec will operate a number of radar units and arrays of digital acoustic bat detector systems at select sites located 6 to 20 miles off of the coast of Maine, covering a transect of nearly 150 miles from Casco Bay north to Machias Seal Island. Stantec scientists will be monitoring the data for information on the offshore presence or absence, timing, flight heights, and passage rates of bats and birds moving south during the late summer and fall migration season.

The Maine Department of Environmental Protection has released its answers to questions and concerns raised earlier this year about a proposed wind-power project in Roxbury. As part of its review process, the department convened its public meeting on Feb. 18 to gather information and questions people had about the Record Hill Wind project. It proposes to site 22 wind turbines on Roxbury ridges running from Partridge Peak to Record Hill on the west side of Route 17.

As planners and developers zero in on locations for offshore wind turbines along the Maine coast, researchers such as Wing Goodale are trying to follow the birds. Goodale, a biologist with the BioDiversity Research Institute in Gorham, is about to release a report and a preliminary map of bird populations along the Maine coast. It's one of several efforts to prevent, or at least reduce, conflicts between offshore turbines and the animals that live in or pass through coastal Maine.

The Maine Department of Environmental Protection issued First Wind of Massachusetts a permit Tuesday to build a 40-turbine industrial wind site for $130 million on Rollins Mountain in Burlington, Lee, Lincoln and Winn. "The Department finds that the applicant has demonstrated that the proposed project will provide significant tangible benefits to the host community and surrounding area,".

First Wind of Massachusetts' proposed $130 million wind farm and an associated 115-kilovolt power line might affect an Essential Fish Habitat for Atlantic salmon, but its impact will be minimal if precautions are taken, the U.S. Army Corps of Engineers said Tuesday.

More than 30 people expressed their concerns about a massive power line upgrade project proposed by Central Maine Power at Lewiston City Hall Monday night during a public hearing before Maine's Public Utilities Commission. About 70 people were present. ...Nearly all of those who spoke before Commissioners Jack Cashman, Sharon Reishus and Vendean Vafiades were apprehensive about the project, anticipating noise pollution, loss of property value and health risks.

Wiscasset is being considered for the largest energy development proposal - and potentially the largest development project of any kind - in the history of the state. A Toronto entrepreneur who has developed Canadian wind farms has floated the idea of building a massive $2 billion underground hydropower station at the old Maine Yankee nuclear power station site. The project would be one of the first of its kind anywhere. The proposal raises questions about impacts on the Back River and groundwater, and it would use as much energy as it creates.

Diane Winn doesn't dispute the need for clean, renewable energy -- the kind provided by wind turbines and hydroelectric dams. But Winn and Marc Payne, her partner at Avian Haven Wild Bird Rehabilitation Center, are all about saving injured or abandoned wild birds. Wind turbines provide clean energy, but birds often die when they fly into turbines, and the noise the machines make can disrupt bird and human alike. For those reasons, Winn and Payne say they would close their North Palermo Road facility if Beaver Ridge Wind, an affiliate of Competitive Energy Service, builds three electricity-generating wind turbines on nearby Beaver Ridge. "No one argues with the basic fact that turbines kill birds," Winn said. "The only issue is how many are killed, and whether those numbers impact species populations."

On Capitol Hill, the Audubon Society is leading the fight to increase production of climate-friendly power. So why are Audubon enthusiasts battling a wind farm that could help meet that goal? For one thing, there are trout in nearby streams, which activists say are at risk from chemical and sediment runoff from construction of 30 turbines, each soaring about 400 feet -- taller than the Statue of Liberty. Then there are the bats and hawks, which might be puréed by the giant blades that would catch the wind gusting along the Allegheny Mountains of Western Pennsylvania. "They're enormous," says Tom Dick, a retired veterinarian who founded the local Audubon chapter. "When you start looking at this, it's like, 'hell, this is not right.'"

The Black Nubble Wind Farm, which calls for 18 turbines on the western Maine mountain, will go before the public Wednesday, Thursday and Friday at the Sugarloaf Grand Summit Conference Center in Carrabassett Valley. ... The Black Nubble proposal is a smaller version of the Redington wind farm proposal, which was rejected by Land Use Regulation Commission members in an unusual 6-1 vote in January that went against the recommendation of its own staff.

Three environmental organizations agreed to back the proposed Kibby Mountain wind-power project in Franklin County after the developer agreed to pay $500,000 to protect several high-elevation acres in Oxford County. According to a late Tuesday afternoon report, the Appalachian Mountain Club, Maine Audubon and Natural Resources Council of Maine negotiated the deal with TransCanada Maine Wind Development Inc.

The state’s largest wildlife conservation organization commends the commissioners of Maine’s Land Use Regulation Commission for their 6-1 decision today to deny a permit for a controversial wind-power project sited in a high-mountain Western Maine area zoned for protection and home to rare wildlife. “Today we have seen LURC’s commissioners take action for which all Maine citizens can be grateful: They have upheld the laws that protect unique, spectacular areas in Maine,” said Jennifer Burns, staff attorney and advocate for Maine Audubon.

"It's a difficult bird to study because it's distributed across a fragmented range of mountaintops which we sometimes refer to as 'sky islands.' We estimate the total population to be between 20,000 and 40,000 birds," Rimmer said. The bird's habitat faces potential threats from ski area development, communications tower construction, wind energy projects, acid rain, mercury and global warming.

Charles B. Cooper, a Massachusetts-based consultant who has been retained by Maine Tidal Energy Co., said the company is developing new technology for its Maine and national tidal energy projects. The tidal in-stream energy conversion units, which could be used in the Kennebec River, would resemble a tall fan with a giant hole in the middle of the section where the blades would be located. Portions of blades, or propellers, would extend 20 to 50 feet outward through the rim of the fan. As the tides flow in and out of the river with each lunar cycle, the blades would rotate slowly -- in the range of three to 10 revolutions per minute, Cooper said.

BREWER - As wind power begins to blow into Maine, state regulators on Wednesday considered its potential to squeeze increasingly expensive - and less environmentally friendly - fossil fuels out of the region's energy mix.
