People listening to policymakers debate the nation's energy future might think: Just erect a lot of wind turbines, and problem solved. Or install a bunch of solar panels, and let the sun do the work. But renewable energy alternatives present costs and challenges just like traditional energy sources - coal, natural gas, nuclear and hydropower.

Portland-based Keppel Prince Engineering, which makes about 40% of Australia's wind turbine towers, has indicated it may need to lay off 150 staff because of lack of work. Keppel Prince's chief executive, Steve Garner, told Green Left Weekly a big problem is that the companies it has contracts with can't access Renewable Energy Certificates (RECs) to support their projects.

Owners of a wind-power company set to erect 22 turbines on local hills have decided to delay the project by a year because the energy market has fallen in the recession. Record Hill Wind LLC is building a $120 million wind farm along the 4-mile ridgeline that connects Partridge Peak, Record Hill and Flathead Mountain. The company had planned to put up the turbines next year, but now says it will be up and running in 2011.

Saying that they are paying close attention to Vinalhaven's community wind project, town officials this week agreed to a preliminary feasibility study for a wind project atop Ragged Mountain. While no project is now in the pipeline, anemometers placed on the mountain three years ago found that the town has "a serious wind resource," said Jeff Lewis, chairman of the Camden Energy Committee. ...Any project ultimately would be put to a town vote, Lewis said. That won't be a slam-dunk for wind power proponents, according to Baker. "If you thought Vinalhaven was iconic, try messing around with the Camden Hills," he said.

The city thought it was ahead of the curve back in 2007 when it bought a windmill that was supposed to provide power for a transportation center built around a station for the Downeaster train. The $200,000 windmill never came close to meeting expectations, but even that was OK. The city had an agreement in which the manufacturer would pay the difference between the value of the anticipated electricity and the value of the actual output.

Robert Gardiner, a public broadcasting executive-turned-wind power developer, fielded questions from the audience about the so-called Highland Wind project. It's a $250 million development that would place 48 wind turbines in a single-file, southeasterly row along four peaks. It would likely be visible from the Appalachian Trail. ...I'm very concerned about the mountaintop removal," says Greg Perkins, the owner of the home in Highland Plantation that would be closest to the wind farm, about a half-mile away. He's also a soil scientist. "I really think we need to rethink this whole wind power thing in Maine. It doesn't create that much energy and for what we're losing, there's no balance to it. So I really think we need to rethink it."

Folks living in Dixmont voted Thursday night on an ordinance that would regulate wind power development in their town. The issue arose when a company began looking into the prospect of placing ten wind turbines along Mount Harris in Dixmont. For the past nine months the local planning board has been researching the effects of such projects on residents living nearby.

Longtime environmental activist and wind-power supporter Jonathan Carter of Lexington Township joined forces this month with a grassroots coalition trying to stop sprawling industrial wind farms atop Maine's mountains. Carter, a former Green Party gubernatorial candidate, is the director of the Forest Ecology Network, which was created to protect, preserve and defend Maine's native forest environment through public awareness, grassroots citizen activism and education, according to its Web site. ..."This isn't simply (not in my backyard)," Carter said. "These mountaintops are unique. They're rare. To destroy them is, in my thinking, extremely inappropriate and shortsighted."

Power producers have installed more than 500 megawatts of wind energy generation in Wyoming in the past year. One driver behind the wind boom presumably is action by other states in the West to require that utilities use certain percentages of renewable energy in their power supplies -- called renewable portfolio standards. ...That has many speculating whether renewable portfolio standards in other states are driving up rates in Wyoming, where there is no such requirement.

The Selinger government is considering a bailout deal to rescue the financially floundering wind farm slated to be built near St. Joseph. Following some pointed questions from Tory MLA Cliff Graydon during a committee hearing late Tuesday night, Finance Minister Rosann Wowchuk acknowledged Pattern Energy has approached the government for funding and that the province is considering it.

Senate Democratic leaders said Tuesday they would put off debate on a big climate-change bill until spring, in a sign of weakening political will to tackle a long-term environmental issue at a time of high unemployment and economic uncertainty. Legislation on health care, overhauling financial markets and job creation will be considered before the Senate takes up a measure to cap emissions of carbon dioxide and other gases linked to climate change, Senate Democratic leaders said Tuesday.

Dignitaries, schoolchildren and more than 400 islanders crowded Tuesday morning around the base of a massive wind turbine to officially dedicate the Fox Islands Wind Project. ...While it seemed clear that the vast majority of residents at the ceremony were thrilled with "their" turbines, a small but vocal group of islanders who live close to the turbines has expressed deep concerns about the noise, flickering red lights and potential negative effects on health and well-being. "Last night, it was just throbbing," said David Wylie, who lives about a half mile from the turbines. "Whump, whump, whump."

Two years ago, a company started looking into the potential for placing wind turbines along Mt. Harris in Dixmont. Since then, local residents have been talking about what that could mean for them-- and Thursday, the issue comes to a vote. Mt. Harris Wind had plans to build about ten turbines along this ridge in Dixmont, says project partner Andrew Price.

The solicitations have been flooding people's mailboxes lately: pay a bit more on your electricity bill for 100 percent clean wind power. Or, the fliers say, buy "green power certificates" to offset your global warming emissions. Close to a million electricity customers have signed up for such payments voluntarily, and the amount of electricity sold in this way has nearly tripled since 2005, amid rising concern about climate change and energy security. But the participants are in a distinct minority, with a sign-up rate of only about 2 percent in programs run by utilities.

Supporters of liquefied natural gas terminals have thrown a late snag into what has been an orderly process to create rules for developing multibillion-dollar energy corridors in Maine. LNG representatives want to extend the current moratorium on energy corridors and create a government commission to do more reviews. Their proposal was filed late last week with the special study group already debating policy for energy corridors.

The High Court has thrown out a legal bid that had the potential of derailing the drive to achieving the UK's ambitious wind energy targets. Mr Justice Cranston rejected a challenge to the authority of South Norfolk Council and their decision to grant planning permission for a wind farm development at Lotus sports car factory. Campaigners had argued that the local authority had acted unlawfully because it had not considered the impact of the scheme on local residents.

In the distance, the dark, low expanse of the island is punctuated by three white lines jutting through the horizon. Three giant wind turbines rise from the interior of the island, visible from miles away, above pines, above homes, above Vinalhaven's granite bones. And on Tuesday, the $14.5 million Fox Islands Wind project officially goes on line with a ribbon-cutting event ...The Lindgrens said the noise can be more intrusive then they were led to believe it would be. The noise is constant, said Britta Lindgren, like a jet passing overhead, "but it never passes." And there's an odd pressure in the air, indefinable, like low frequencies that have begun since the turbines started.

Umatilla County is again asking the Oregon Energy Facility Siting Council to do away with a 400,000 acre box designated as an energy generation area. The box sits along the north border of the county, in about the center. It includes Milton-Freewater, Adams, Athena, Weston and some of Pendleton. In 1999 the siting council designated the EGA in response to a legislative mandate. The Oregon Department of Energy has been unclear on the EGA's original purpose, but some have said it was meant to analyze cumulative effects of many small wind farms in a given area.

Early work on a unified wind turbine policy was met with many questions at Thursday's Burleigh County Planning Commission meeting. Bismarck City Planner Gregg Greenquist said the policy should be split between "household wind energy systems" and larger wind farms. Greenquist said a large expansion is planned for a wind farm near Wilton into the Burleigh County jurisdiction.

A Patrick administration proposal that critics say would strip local control from the siting of wind turbines is still awaiting action on Beacon Hill. And some West County town officials say revisions in the legislation don't go far enough in addressing their concerns. The Hawley Planning Board wrote this week to Gov. Deval Patrick and area legislators opposing the Wind Energy Siting Reform Act.
