Chemical fingerprints implicate wind turbines killing bats

The study found that half of red bats killed in the area were not local residents and probably summered at locations far from the wind turbines, whereas nearly all of the hoary bats summered locally. The red bats represented a single, massive breeding population in the hundreds of thousands to millions of individuals. In contrast, the hoary bats represented a relatively small group.

White Pines Wind appeal decision:15-068 HIRSCH V. ONTARIO (MOECC)

Ert-white-pines-decision_thumb The Ontario Environmental Review Tribunal released this decision partially granting an appeal of the Province's decision to approve the White Pines wind energy facility. The panel upheld the appeal because of the risk of serious and irreversible harm to the Little Brown Bat and Blanding’s Turtle. The White Pines wind facility, as proposed, consists of 29 wind turbines with a nameplate capacity of 59.45 megawatts (MW). The Project will be located within the ward of South Marysburgh and a small portion of Athol, Prince Edward County. The background details of the case before the Tribunal are provided below. The full decision can be accessed by clicking the links on this page.

Decades of bat observations reveal uptick in new causes of mass mortality

Collisions with wind turbines worldwide and the disease white-nose syndrome in North America lead the reported causes of mass death in bats since the onset of the 21st century. These new threats now surpass all prior known causes of bat mortality, natural or attributed to humans. A comprehensive study reveals trends in the occurrence and causes of multiple mortality events in bats as reported globally for the past 200 years, shedding new light on the possible factors underlying population declines.

Multiple mortality events in bats: a global review

Multiplemortalityevents-bats_thumb This new study examines bat mortality events including impacts from operating wind energy facilities. The global expansion of industrial wind energy production has resulted in multiple fatalities reported from wind turbines in North America, Europe, South America, Africa, and Australia, most during the past decade (See Appendix S6 of the report). Estimates that include bias corrections range to thousands of bat deaths annually at some facilities. Cumulative deaths of bats at turbines tabulated for Europe for the period 2003–2013 involved 5626 bats of 27 species in 18 countries, only a fraction of the likely mortality. In some regions, deaths of some species at wind turbines far exceed other known sources of mortality (Cryan 2011). Causes of susceptibility to wind turbines are not fully understood.

Industrial wind is destroying Iowa's eagle habitats

The bald eagle recovery program in Iowa is perhaps our state’s best wildlife management success story to date, but progress is being lost due to the mass killing of bald eagles by industrial wind turbines. This conflict between industry and environment is now playing out near Fairbank, Iowa located in Fayette County, where shell companies Mason Wind (parent firm is China’s largest naval defense contractor) and Optimum Renewables (parent company is a German wind services firm) are attempting to build their wind farm in an area known for bald eagle habitats.

Cape and Islands population of threatened bats hangs on

As for the wind turbines, any federally run turbines are required to shut down when the bats are migrating in the spring or fall, McCumber said. The base has three wind turbines that provide power to its groundwater treatment plants and two for the PAVE PAWS radar station. Typically, it’s on nights when the winds are light or nonexistent that the turbines stop spinning because the bats are likely on the move, he said.

Wind, Birds And Bats: Recent Legal Migrations

On Aug. 11, a California district court overturned an FWS rule authorizing 30-year BGEPA take permits for failure to comply with NEPA. The FWS already commenced a NEPA review and aims to finalize revised regulations by 2017. This decision does not prohibit further issuance of five-year BGEPA take permits. Only one five-year permit, and no 30-year permits, has been issued to date, although several applications are pending.

Wind Industry Plans Serious Changes to Protect Bats

Researchers and conservationists first raised the alarm about wind turbines killing bats more than a decade ago. Studies have since suggested that migratory bats, which roost in trees and fly long distances in the spring and fall, are attracted to the turbines and their towers for some reason. When they fly too close, they collide with the spinning turbine blades and are killed. Estimates of just how many bats are dying range from the tens of thousands to hundreds of thousands.

Another reason to just say “No”

Much of the scenic beauty for which Maine is so widely known will be despoiled. The stated 2,700-Megawatt goal of Maine’s Wind Energy Act would require as many as 1,500 wind turbines, each hundreds of feet tall, with accompanying access roads and new transmission lines, on up to 300 miles of Maine’s hills and mountains. Those transmission lines, to carry the electricity that could be provided by a single, high-quality conventional generator, will add billions of dollars to New England electric bills.

Concern for bats won't block Ohio wind farm

The 15-page opinion credits the finding by FWS "that the minimization and mitigation measures 'fully offset' the impact of the taking of Indiana bats, and thus, it was not necessary to determine if the plan was the 'maximum that can be practically implemented.'"

Wildlife experts: Huron turbines could kill thousands of bats

The Service’s three-mile setback from Great Lakes shorelines is a recommendation based on areas along the shoreline identified as having the highest habitat value for migrating and nesting birds. Hicks said the agency cannot force developers to apply for permits, but killing an eagle and not having an incidental take permit can result in prosecution. The Service’s 2012 wind energy guidelines are voluntary for developers.

Wildlife and renewable energy: German politics cross migratory bats

Voigtetal_2015ejwr_thumb This important study concludes that more than 250,000 bats are killed annually due to interactions with German wind turbines, and total losses may account for more than two million killed bats over the past 10 years, if mitigation measures were not practiced. The abstract to the paper is provided below. The full paper can be accessed by clicking the links on this page.
