Director of Science Nature Conservancy in Wyoming, Holly Copeland remarked, “Over a half million birds and about a million bats, a study in 2013 by Smallwood, et al showed. And if you run those numbers out for Wyoming there are about 5000 grassland birds we would be losing every year…there was a paper that showed 20 eagles and in addition to that Duke Energy reported 52 eagles as well.”
The staff of the Ohio Power Siting Board has recommended that the six wind turbines the Lake Erie Energy Development Corp. (LEEDCo) has proposed building 10 miles offshore operate only during daylight hours for 10 months out of the year while experts determine whether technology designed to detect bird and bat collisions with the turbines is effective. LEEDCo has tried without success to negotiate a compromise. The issue and other issues regarding sophisticated radar systems are now headed into hearings that begin Sept. 24 in Columbus.
The plan is part of MidAmerican’s request for a 30-year U.S. permit to allow for an average of 10 turbine-related incidental bald eagle deaths per year across the company’s Iowa footprint.
If extrapolated to all of Britain’s wind farms it would mean 80,000 die each year from colliding with the blades. The number increased with blade length with some individual turbines responsible for the deaths of five bats each month.
The mystery of why more than 80,000 bats are killed by wind turbines in the UK each year may finally have been solved. Scientists found the winged creatures are naturally drawn to sources of red light – an attraction that can confuse them on migration routes.
“It’s a conservation conundrum,” said Phillips. “We want green energy, but are we willing to do that at the extinction of our only native land mammal?” Fish and Wildlife officials anticipate the draft of the programmatic environmental statement and each wind energy project’s habitat conservation plan will be available for public review and commentary by the end of this year.
The Ohio Power Siting Board has recommended conditional approval of the $126 million Icebreaker six-turbine wind turbine project proposed by the Lake Erie Energy Development Corp. 8 to 10 miles northwest of downtown. But the staff has included more than 34 conditions. The six-turbine wind farm is expected to look similar to this offshore wind farm near Block Island in the Atlantic Ocean.
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.
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.”
