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 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.
But Angus Hutchinson, the authority’s principal development control officer, said there were many species of bats and some could be severely affected by the turbine. He recommended to members that the application be rejected as a result of this, despite it having been recommended for approval in their papers.
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.
Plans for a controversial wind farm on the edge of York have been delayed by a year - because of concerns about the impact on bats and other wildlife. Banks Renewables had hoped to lodge a planning application for a 15MW wind farm in fields west of Copmanthorpe by the end of this year.
Scientists found the blades of wind turbines were a major threat to bats particularly when they are migrating. ...Writing in the journal Science, the researchers estimated that bats could be worth billions to agriculture around the world.
More than a thousand letters have been received objecting to plans to build two wind turbines in Grange Moor, Huddersfield, claiming they would be too close to a school and homes and would ruin the skyline of a scenic rural area. Councillors are being urged to throw out the plans because officers say insufficient information has been provided.

A 65ft blade from the 290ft turbine fell off and a second was bent in the mysterious incident in Conisholme, Lincs, on Wednesday. ...Scientists at manufacturers Enercon have been looking into the mystery, and dismissed the theories that either a chunk of ice thrown from another turbine, or frozen urine dropped from a passing plane, was the cause.
Councillors have refused to let a school press ahead with a plan for a wind turbine because of fears it will kill bats. Askam Village School had asked Barrow Borough Council for permission to install a 11.7-metre tall turbine in the school grounds, about 40 metres from Lots Road. But Natural England, the government agency responsible for bat conservation, objected and urged the council not to allow it.
Windfarms are blamed for the deaths of large numbers of birds, including the threatened hen harrier, that crash into the spinning blades. But, what's now emerging is that bats are probably more at risk than birds. Up to now little has been known about the effects of windfarms on bats. Something that has mystified researchers, however, is that bats found dead around turbines had no visible injuries. So, are windfarms killing bats without touching them? It seems they are. ..."If bat fatalities continue this has the potential to be really serious. The problem is likely to get much worse with the proliferation of turbines, not just from large power companies erecting them but private individuals doing so as well," Ms Baerwald pointed out.
I am extremely concerned at the detrimental impact the construction of wind turbines on the land adjacent to High Elms Lane, Benington could have on wildlife. It is well known locally that this site supports a large and varied wildlife and many of the species are of national and international importance. It has taken a long time and sympathetic farming to encourage so many species to thrive in this area. A total of 26 mammal species (not counting bats) and 75 bird species have been recorded around the proposed wind farm, along with various amphibians and reptiles.
A series of events on bats look set to be overshadowed by problems affecting the mammals' chances of survival, according to an expert. Anne Youngman, the Bat Conservation Trust's Scottish officer, said wet weather may have hit the breeding season for a second year running. ...On the agenda is a presentation on wind farms in mountain areas of Portugal. Ms Youngman said: "Wind farms were a hot topic at the last symposium. "In Germany, there are turbines above forests and the mortality rate of bats has been found to be high.
Plans for a wind farm in north Devon have been rejected on environmental grounds. Torridge District Council turned down the scheme on the grounds of visual impact, noise and the impact on bats at the site near Stibb Cross. Developer Ecotricity is considering whether to appeal against the decision.
Plans for Europe's largest wind farm could still be approved if ministers and environmental agencies can be persuaded to change their interpretation of rules protecting wildlife, councillors in the Western Isles heard yesterday. Ministers indicated last month that they are "minded to refuse" Lewis Wind Power's (LWP) plans for a 181-turbine development on the environmentally sensitive Lewis peatlands, although a final decision has yet to be made. Developers have until 15 February to respond. Following a special meeting of Western Isles Council yesterday, a spokesman for the authority said: "There is determination to do what we can to bring to the Scottish ministers' attention the opportunity that is in danger of being passed up here." ...the council is challenging the government's conclusions and insists the interpretation of environmental rules is too strict. It
Despite common misconceptions, the animals are vital in the food chain to keep down the level of insects. ...Evidence is also mounting that wind turbines are killing bats. Louise Oliver, of the Norfolk and Suffolk Government Team from Natural England, is working with the bat conservation group. Their research has found people with wind turbines often find dead bats near the machinery first thing in the morning.
PLANS to build a wind turbine in the grounds of a school could be blown away by a colony of bats. ...In response to Mr Swain's comments at the meeting, a council officer said if there were any bats in the area, government environment department DEFRA could make an objection to the application.
But then there is the problem of wind turbines. Research in the US and Europe has linked big turbines to bat mortality. In Britain, there has not been enough research yet, but bat conservationists are particularly concerned about micro turbines on houses. "We've had reports of bats killed by micro turbines. It's possible they pose a greater threat because they could be placed right where bats regularly commute," says Williams. "We need to undertake more research. BCT naturally supports all these strategies to reduce energy waste and increase renewables. Our only fear is we don't know what the impacts are on bats and if they go ahead on a large scale before we know, it may be too late."
