Koch proposes shutting down wind turbines at times when bats' migration path puts them at risk from the huge, rotating blades. But if bat protection is to be taken into consideration when designing policy – on wind energy development, forestry, agriculture and the use of pesticides – solid data is essential.
Southern Arizona’s only wind-energy farm is under a federal criminal investigation because its turbines killed an endangered bat and a federally protected golden eagle, law enforcement officials say. ...if the company had chosen to seek permits in advance that would have allowed it to kill a certain number of the protected species.
“Hawaii has been through so much trial and error, and we don’t even have all the information at the table,” Tuivaiti said. “We’re still trying to figure out the population. We’re still trying to figure out about the bats themselves, and here we are just kind of playing God. . . . If we keep taking, we’re going to have nothing left.”
The figure is scary: The approximately 6,000 wind turbines are operating in France today may have caused the death of 1.6 million bats over the period 2002-15, according to the Environment Agency and the control of energy (Ademe).
It is not in the interests of the wind industry or Scottish Government to let the public know how many thousands of birds and bats their turbines are killing. The public will not like it and may well demand the slaughter ceases and that would mean no more turbines because it is impossible to stop.
The OPSB postponed the adjudicatory hearing in response to a request from its staff to suspend the procedural schedule in this case to allow additional time to obtain more information from Icebreaker Windpower on the pre- and post-construction radar technology monitoring protocol selected for use at the project site for determining project impacts.
This important study provides the most complete dataset of bat flight height distribution. Highlights include:
Two studies Apex Clean Energy is planning to provide to help assess how its Galloo Island Wind project could affect bats are inadequate for determining the potential impacts, argues avian advocate Clifford P. Schneider.
"Currently, all major wind farms in Hawaii have exceeded their amount of take that they've been approved for. In fact, the two existing wind farms on Oahu have already killed over 70 bats in just a few years of operation," said Maxx Phillips, an attorney for Keep the North Shore Country.
The recent cancelation of the proposed Camp Perry demonstration windmill was celebrated by the American Bird Conservancy of Virginia, and the Black Swamp Bird Observatory — a local bird research, conservation and education organization headquartered in Oak Harbor.
GREAT FALLS, Mont. – A wind farm in Montana might be killing more birds and bats than expected, according to preliminary findings of a study by Montana Fish, Wildlife and Parks.
A preconstruction acoustic survey for bats predicted that the wind farm’s impact would be low, but the preliminary results of the study show it’s been higher than anticipated. Over the first six months of the post-construction study, FWP is estimating with 95 percent confidence that the turbines killed between 120 to 397 bats with the figure likely 221 or about nine bats per turbine.
Five different species of bats have been found dead below turbines in southern Sweden by the researchers. What they all have in common is that they prefer to hunt at higher altitudes, making them more vulnerable to the rotating blades than peers. ...if nothing is done to limit the deaths, numerous populations are at risk of getting rare, Green said.
“The proposed wind farm would be disastrous for Africa’s Critically Endangered vultures, and many other important bird species, and contradicts Kenya’s commitment to the Convention on Migratory Species.”
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.

As wind farms statewide are killing more Hawaiian hoary bats than expected, a Maui wind farm is asking the state to increase the amount of endangered bats and nene it’s allowed to incidentally kill.
Led by researchers at Austin, Texas-based Bat Conservation International, the paper estimates that if new mitigation measures to prevent bats from colliding with spinning turbine blades are not quickly implemented, "the hoary bat population could decline by as much as 90 percent in the next 50 years."
A Maui wind farm wants the government to increase the number of endangered Hawaiian hoary bats it is allowed to kill, after passing the limit 15 years ahead of schedule. SunEdison Inc., owner of the 21-megawatt wind facility called Kaheawa Wind Power II, requested to increase the amount of hoary bats the facility is allowed to kill to 62 from 11 bats over its 20-year project with the Department of Land and Natural Resources. DLNR proposed to approve the increase in a bulletin called the Environment Notice from the Office of Environmental Quality Control released Thursday. “The proposed action would result in benefits at the local and state level by producing clean, renewable energy in line with Hawaii’s clean-energy goals,” DLNR said in the notice. “Effects to the Hawaiian hoary bat and nene would be offset by funding research, restoration, or land acquisition to mitigate for the take of each species. Based on the mitigation efforts, no adverse impacts to either species is anticipated.”
