ABC brief supporting disclosure of bird-bat mortality: Blue Creek Wind facility

Brief_thumb This brief, filed before the Ohio Court of Common Pleas in Franklin County, Ohio, responds to Iberdrola's (Avangrid Renewables) action to stop any public disclose of bird/bat mortality data at its Blue Creek wind facility. Iberdrola has argued that the number of birds and bats killed by its turbines is a “trade secret” protected under Ohio law. The introduction and summary of arguments for why Iberdrola's claims are not supported by Ohio law are provided below. The full brief can be accessed by clicking the links on this page. The original complaint can be found here.

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.

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.

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.

Behavior of bats at wind turbines

Pnas-2014-cryan-1406672111_thumb This important paper published in the Proceedings of the National Academy of Sciences examines the unprecedented numbers of tree-roosting bat fatalities at operating wind turbine facilities and the behavior of the bats near the turbines. The abstract of the paper along with the significance of the findings are provided below. The full paper can be accessed by clicking the links on this page.

Wind farm facilities in Germany kill noctule bats from near and far

Journal.pone.0103106_thumb In this recent study, researchers present a comprehensive study on the breeding provenance of endangered and protected noctule bats killed at German wind turbines, showing that individuals from local and distant populations are among the recorded fatalities. The results provide a first step on the way towards an evaluation on how bat fatalities at wind turbines might impact local and regional populations in migratory bat species. The abstract of the paper is provided below. The full paper can be accessed by clicking the link(s) on this page.

Offshore observations of Eastern Red Bats (Lasiurus borealis) in the Mid-Atlantic United States using multiple survey methods

Journal.pone.0083803_thumb This important paper examines bat movement and foraging offshore along the United States eastern shore. The authors raise the concerns that migratory bats are at risk of mortality due to offshore wind turbines. The abstract and a portion of the paper's background section is provided below.

Bats Killed in Large Numbers at United States Wind Energy Facilities

Bioscience-2013-hayes-975-9_thumb The development and expansion of wind energy facilities is a key threat to bat populations in North America. Dead bats are being found underneath wind turbines across North America, and bat fatalities have been documented at almost all of the wind facilities at which thorough bat surveys have been conducted. This paper examines the scale of the problem. The abstract and conclusions of the paper are provided below. The full paper can be accessed at the links on this page.

Evaluating Bird and Bat Post-Construction Impacts at the Sheffield Wind Facility, Vermont

Sheffield_wind_2012_annual_report_final_3-25-2013_thumb The Sheffield Wind Energy facility, a 40 megawatt project that went into service in October 2011, released the first season of bird/bat mortality. Total bird fatality estimates for the project site for the entire season was 211 (95% CI: 147, 321), with an estimated 13.17 birds killed per turbine (95% CI: 9.20, 20.05). A total of 87 bats of three species from 1 April-31 October, all of which were migratory tree-roosting bats. Bat carcasses were found at all 16 turbines. The full report can be found by clicking on the links at the bottom of this page.

The effect of wind energy development on bats

This report from Boston University is about a year old but well worth the read. "For such small animals, bats have unusually low reproductive rates, with an average mother producing only one or two young each year. At this rate, it could take decades to reverse dramatic losses to bat populations. The hoary bat, one of the most commonly killed species by wind turbines in North America, may not be able to sustain anticipated losses to its population within the next ten years."

Population-level impact of white-nose syndrome on the endangered Indiana bat

11-mamm-a-355.1_thumb The important report examines the impact of White Nose Syndrome on Indiana bat populations and the opportunity, if any, for the populations to recover. In addition, renewable energy generation has resulted in the erection of thousands of wind turbines in the midwestern United States, resulting in significant mortality of both migrant and resident bats. The abstract of the paper is below. The full report can be accessed by clicking on the links at the bottom of this page.
