Wind turbine pressure change kills bats, research may help prevent future deaths

Miles away, wind turbines sat motionless in the windless night. Their spinning blades can be deadly to bats, bursting capillaries in their lungs before the blades hit their tiny bodies. Three Wyoming bats are particularly susceptible when they migrate from summer to winter ranges. Keinath and Abernethy were looking for bats to tell them which, if any, species called the area home.

Bat-Taking Permits, An open letter to Vermont's Agency of Natural Resources

These bat species are far more important than First Wind's profits. There's presently a glut of generation in New England and First Wind's intermittent power does nothing more than add to the surplus on the grid. ...First Wind agreed to curtailment during low wind speeds at certain temperatures and now seems to be complaining that such curtailment won't be profitable. Too bad for them.

Wind turbines may halve bat activity

The research, funded by the Leverhulme Trust, involved halting microturbine movement at 20 sites across the UK and examining the effect on bird and bat activity. Bird activity was not significantly affected but bat activity was 54% lower in close proximity to operating turbines.

Bats & blades: More research needed on bat, wind farm fatalities

Laura Ellison is an ecologist with the U.S. Geological Survey in Fort Collins, Colorado, who has spent the last 20 years studying bats and other small mammals. Earlier this month she presented on the bat and wind farm issue at the North America Congress for Conservation Biology. "The newer, larger turbines seem to be worse for bats," Ellison said.

White-nose syndrome spreads west

Scientists have discovered that the fungus exists in Europe but bats there seem to be unaffected by it, possibly because they have been exposed to it for a longer time and have developed an immunity, explains Kilpatrick. White nose appears to sicken bats while they are in caves because their immunity is suppressed during hibernation, he said.

Sheffield Wind files for bat permit, conducts study

Sheffield Wind, whose 16-turbine, 40-megawatt utility scale project in the Northeast Kingdom went on line last fall, has filed for the permit because a fungus has decimated Vermont bat populations and placed them on the endangered or threatened species list. "White-nose syndrome" has caused mortality of more than 90 percent of the population of little brown and long-eared bats in the state.

German wind farms can kill bats from near and far, research suggests

Previous studies have already highlighted that more than 200,000 bats are killed each year by German wind turbines. Researchers are convinced that such high mortality rates may not be sustainable ...Voigt calls for stronger legislative agreements. The large-scale development of wind farms throughout Germany may have negative consequences for even remote ecosystems in northeastern Europe.

Fixing wind power's bat problem

A fungal infection known as white-nose syndrome has killed at least 6 million bats in North America since it was discovered six years ago; some species, such as the Indiana bat and the gray bat, may go extinct as a result. The economic impact of losing so many insect-eating animals is staggering: A study published in Science last year estimated that bat deaths could lead to annual agricultural losses in North America of more than US $3.7 billion.

The trouble with turbines: An ill wind

But the concern is that turbines threaten species that are already struggling, such as bats, which in North America have been hit hard by white-nose fungus. Another vulnerable group is raptors, which are slow to reproduce and favour the wind corridors that energy companies covet. “There are species of birds that are getting killed by wind turbines that do not get killed by autos, windows or buildings,” says Shawn Smallwood ...Smallwood has found that Altamont blades slay an average of 65 golden eagles a year. “We could lose eagles in this country if we keep on doing this,” he says.
