NaiKun offshore wind farm presents environmental dilemma

It's a dilemma that forward-thinking, environmentally conscious people do not want to face: Will moving toward carbon-free energy sources mean disrupting bird migration routes and having a negative impact on wildlife populations? This weekend sees the July 12 deadline for public comments on the massive NaiKun wind farm proposed for Hecate Strait. ...The problem arises, however, that this exact location, the shallow water around McIntyre Beach and Rose Spit, is a designated important bird area under the BirdLife International program that lists critical sites for bird populations in over 200 countries worldwide.

Digby wind project slowed; Environmental approval requires more information

Plans to build a wind turbine park for Digby Neck hit a snag this month when Nova Scotia's deputy minister of environment told an executive at Skypower Corp. in a letter that more information about the project is needed before an environmental assessment application is approved. Skypower Corp. of Toronto and Scotian Windfields of Dartmouth have jointly proposed a 30-megawatt wind farm on Digby Neck comprised of 20 wind turbines, each generating 1.5 megawatts of electricity.

Environmental assessment decision throws caution to the Digby Wind Power Project

Nova Scotia's Deputy Minister of Environment has issued a decision on the Digby Wind Power Project's Environmental Assessment Report that appears to leave the project twisting in the wind. ...In a June 19 letter addressed to SkyPower Corporation VP Charmaine Thompson, Deputy Minister of Environment Nancy Vanstone states quite simply, "I have determined that the registration information provided is insufficient to allow me to make a decision."

Emu farmers worry about windmills

The noise and vibration from heavy equipment has been known to frighten emus to death, Debi VanTassel said in a recent interview. She wonders what living near a wind turbine will be like. Ms. VanTassel has another worry, though. Her husband is an epileptic who may have grand mal seizures. They can't have wallpaper in their home because the patterns could seem to come alive and bother Mr. VanTassel.

Birds die in places other than in Alta. oilsands: MP

The 500 ducks that died in the Alberta oilsands pale in comparison to the thousands of birds killed by cats or by crashing into Toronto office towers or flying into windmills, says Conservative MP Brian Jean. ...At the committee, he questioned federal officials about "how do you balance" 500 ducks who died in an oilsands tailings pond with 6,000 killed annually on Toronto skyscrapers and 200,000 caught in wind turbines.

Wind turbines and the disappearance of our birds

It is with great· sadness that we have come to the realization that the "Mohawk Point Wind Farm" has virtually destroyed our backyard avian population. (Lowbanks Wind Facility, Haldimand County, Ontario) ...The only tenants in the nesting box and brand new $120.00 Purple Martin House will be sparrows. The constant drone of the turbine closest to us is, in my opinion, comparable to the sound of the heavy duty cycle on a clothes dryer. The drone continues non-stop, 24 hours a day, and it will be interesting to see how long the sparrows and starlings continue to put up with it.

Wind farm developer drops oil-spill appeal

The company building the wind plant on Wolfe Island has withdrawn an appeal it had launched to avoid being held responsible for a diesel spill that occurred last fall. Canadian Hydro Developers Inc. had appealed to the Environmental Review Tribunal, an independent provincial agency, after failing to comply with a director's order the Ministry of the Environment issued as a result of the spill. The firm launched the appeal in an effort to have its name removed from the order.

Bats surpassing birds as ecological concern

New research shows that the study of bat mortality at wind turbines should be the primary ecological concern for developers. ...TransAlta has about 189 MW of wind farms operating in southern Alberta and another 162 MW under construction. By analyzing specimens found on one of TransAlta's farms, Robert Barclay, a biological sciences professor at the university, discovered that the vast majority of bats died not as a result of colliding into the turbines, but as a result of a sudden drop in air pressure in the airspace around the turbines - which destroys their lungs.

For the birds

It is time for Ontario to work with citizens and environmental specialists to establish guidelines for the careful development of wind energy (Who Could Object To Wind Power? - Nov. 25). There are some places where wind turbines simply don't belong. ...Build wind developments in the wrong places and the environment will be collateral damage.

U. S. ponders use of offshore wind turbines in Great Lakes; But There Are Environmental Issues At Stake

Imagine sections of the Great Lakes dotted with rows of gleaming, 12-storey turbines, blades whirring in the stiff breeze as they generate electricity for homes and businesses onshore. It's only an idea -- for now. But U. S. government regulators are bracing for an expected wave of proposals for offshore power generation ...Despite its allure as a plentiful source of clean energy, they say, offshore wind power could affect the aquatic environment and commerce.

'Green' wind turbines prove deadly for bats

Bats and wind turbines make a bad mix. In fact, bats have become an unexpected casualty in the burgeoning wind-power industry, with several thousand bats killed by turbines each year in North America. Now studies are being conducted at the future site of a Peace region wind farm in order to save bats from dropping dead near the whirling blades. ...Most of the wind-farm research has been focused on birds, and little is known about the effect on bats, although new studies are beginning to yield clues on how to minimize the impact of the wind farms on the tiny flying animals.

B.C. study to help bats survive wind farms

Bats may never find wind farms as friendly as belfries, but a three-month study in northeast British Columbia is designed to make the power-generating turbines at least somewhat less deadly. Monitoring devices installed by AltaGas at the site of the proposed Bear Mountain Wind Farm have been recording data on the population and migratory routes of bats in the area since July. In later stages of development, the research is intended to help how the company can make its turbines to more bat-friendly.

Bats fatally battered by wind farm effects

Baerwald, whose team checks for carcasses under turbines at the Summerview wind farm near Pincher Creek, Alta., every morning, says bats are one of the unforeseen casualties in the rush to harness wind power. Several thousand of the tiny flying mammals are killed by the turbines each year across North America, with some farms much more deadly than others. Industry officials say they are determined to reduce the death toll but concede it is not going to be easy since so little is known about the nocturnal creatures. ...The researchers dissected 75 corpses and report that 90 per cent died form internal hemorrhaging consistent with "barotrauma," tissue damage caused by rapid or excessive change in air pressure near the rotor blades.

What is killing the bats of Pincher Creek?

Bats are dying as they fly into low-pressure zones around wind turbines. The sudden low pressure causes the air in their lungs to expand and cause tissue damage, called barotrauma. Low-pressure area: most severe immediately out from the blades and decreases as it gets closer to the centre of the turbine. There is also a low-pressure area down the shaft.

Wind turbines to blame for bat deaths: study

Sudden air pressure changes around wind turbines is likely behind the large numbers of migratory bats found dead in southern Alberta, according to a new University of Calgary study. The two-year study found 90 per cent of the studied bats found dead below turbines near Pincher Creek suffered severe injuries to their respiratory systems consistent with a sudden drop in air pressure that occurs near the turbine blades.

Developers should pay for wind turbine vandalism

Accompanying the myth that wind turbine energy will replace fossil fuel energy is denial of the ecological impacts and health effects of wind turbines by governments and promoters. The ugly reality is that wind turbines are a serious addition to the industrialization of quiet rural landscapes, places that people have long valued for quality of life, retirement and recreation. The environmental costs imposed on wildlife and people have been systematically ignored by a political and regulatory system that has corrupted individual and societal freedom and environmental integrity by relegating these values to some distant offshoot of economic growth.
