'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.

Wind Turbines; Offensive industrialization of human space

People have been hoodwinked into promoting wind turbine energy as some sort of Nirvana all while human population growth and per capita energy consumption continue to spiral upward. Turbine energy generation is fueling growth in human population and energy consumption and growth in a false "economy". It is NOT doing the opposite. Matching the folly of the energy replacement misunderstanding is denial by governments and promoters of the ecological impacts and health effects of turbines; the ugly reality is that they are a serious addition to the industrialization of quiet rural landscapes that people have long valued for quality of life, retirement, and recreation. ...Wind turbines are an assault on human well being and act to degrade the human "gestalt". Promotion of wind turbine energy is a case of serious misjudgment by those who fraudulently use green wash to promote their commercial aspirations.

Georgian Bay, wind and beauty

Yet the Ontario Government seems to be committed to opening up this sensitive area to the burgeoning wind-farm industry. In a recent report commissioned by the Ontario Power Authority, Georgian Bay has been singled out as an excellent place to locate offshore wind farms. A number of land-based farms have already been proposed along its shoreline.

Lack of will, lack of funds wiping out migratory birds

Birds are in big trouble in North America. A recent study found 127 species of neotropical migratory birds are in decline. How badly? The Black-chinned Sparrow population has fallen 89 per cent over the past 40 years, the Cerulean Warbler is down 83 per cent, and Sprague's Pipit population has declined by 81 per cent. So drastically have overall migratory bird populations fallen that one scientist who compared weather satellite images over time, found that migrating bird flocks were 50 per cent smaller than they were several years ago. Last week in Washington, Congress began hearings into the crisis and there were calls on the government to boost funding to the Neotropical Migratory Bird Conservation Act.

Wildlife area in crisis at PE Point

Gilead Power, a privately owned renewable energy company, is proposing a wind farm of up to 13, 90-metre high turbines in Ostrander Point Crown Land block, directly west of the National Wildlife Area and in the heart of the Prince Edward County South Shore Important Bird Area. ...now is the time to ask politicians and the candidates the hard questions about this important part of Canada's natural heritage. Is the provincial government willing to protect the integrity of migratory bird habitat and say no to the wind farm at Ostrander Point? Are our leaders in Ottawa ready to ante-up the required resources to get our national wildlife areas off life-support? Demand answers!

Western governors weigh balancing energy, wildlife

Governors from several western U.S. states and Canadian provinces met Sunday to discuss strategies for protecting wildlife that roams their region while also capitalizing on immense energy resources. ...The council´s task will be to identify key wildlife corridors and habitats for wildlife, such as pronghorn antelope, sage grouse and bear. The council will also study ways to protect animal habitat in the face of ever-increasing demand for domestic energy development _ both in the form of oil and gas drilling and new construction of solar and wind generation plants _ the building of new infrastructure for the region´s growing population and the effects of climate change.

Minister of Tourism approves Wolfe Island Wind Project

On June 4, 2008, the Minister of Tourism confirmed the province's approval for the Wolfe Island Wind Project. Premier Dalton McGuinty asked the Minister to step in when the Environment Minister declared a conflict-of-interest on May 29, 2008. Controversy over the Wolfe Island Wind Project centres on the location of a handful of the 86-wind turbines that Canadian Renewable Energy Corporation hopes to build on the island later this year.

Honeybees, wind farms and the triumph of greed over green

Is the proposed wind-energy farm on Wolfe Island an example of a community making environmentally sound choices? The honeybee story has made me skeptical. Are decisions being made because they are good for the environment and the residents of Wolfe Island or because the project is going to line the pockets of the people involved? Are people so anxious to make money they won't wait for an environmental assessment? Has anyone taken into consideration the location of the turbines and their impact on the people who live near the site? Do those residents have a say?

Wind farm plans changed to protect birds

Following a study of the movement of birds at a proposed wind farm site, the City of Summerside has reduced the number of turbines planned and changed their shoreline location. ...Two of the four turbines would go on the shoreline of Malpeque Bay, just east of Slemon Park. The site is recognized under an international conservation treaty signed in 1971, known as the Ramsar Convention on Wetlands.

Draft plan would ban shoreline wind farms

A ban on wind energy projects within 200 metres of the Lake Erie, Lake St. Clair and the Detroit River shoreline is among the many recommendations in the final draft of official plan changes proposed for the County of Essex. Bans would also protect national parks, conservation areas and a host of smaller natural areas, particularly those with endangered or threatened species. The recommendations by the Jones Consulting Group divide the county into four different management areas and requires that proponents show their wind farm proposals won't harm communities or the environment. New policies would protect "heritage resources and significant cultural heritage landscapes." The visual impact of turbines, that could be 120 metres high, has to be weighed for the impact on scenic viewpoints and landscapes.
