Oxford ecologist: "Renewables pose a far greater threat to wildlife than climate change"

Oxford ecologist Clime Humbler has written a must read article on the shocking environmental costs of renewable energy. Wind farms particularly are devastating populations of rare birds and bats across the world, but for ideological reasons environmentalists prefer to ignore the carnage:

Wind turbines only last for ‘half as long as previously thought’, according to a new study. But even in their short lifespans, those turbines can do a lot of damage. Wind farms are devastating populations of rare birds and bats across the world, driving some to the point of extinction. Most environmentalists just don’t want to know. Because they’re so desperate to believe in renewable energy, they’re in a state of denial. But the evidence suggests that, this century at least, renewables pose a far greater threat to wildlife than climate change.
I’m a lecturer in biological and human sciences at Oxford university. I trained as a zoologist, I’ve worked as an environmental consultant — conducting impact assessments on projects like the Folkestone-to-London rail link — and I now teach ecology and conservation. Though I started out neutral on renewable energy, I’ve since seen the havoc wreaked on wildlife by wind power, hydro power, biofuels and tidal barrages. The environmentalists who support such projects do so for ideological reasons. What few of them have in their heads, though, is the consolation of science.
My speciality is species extinction. When I was a child, my father used to tell me about all the animals he’d seen growing up in Kent — the grass snakes, the lime hawk moths — and what shocked me when we went looking for them was how few there were left. Species extinction is a serious issue: around the world we’re losing up to 40 a day. Yet environmentalists are urging us to adopt technologies that are hastening this process. Among the most destructive of these is wind power.
Every year in Spain alone — according to research by the conservation group SEO/Birdlife — between 6 and 18 million birds and bats are killed by wind farms. They kill roughly twice as many bats as birds. This breaks down as approximately 110–330 birds per turbine per year and 200–670 bats per year. And these figures may be conservative if you compare them to statistics published in December 2002 by the California Energy Commission: ‘In a summary of avian impacts at wind turbines by Benner et al (1993) bird deaths per turbine per year were as high as 309 in Germany and 895 in Sweden.’
 A recent study in Germany by the Leibniz Institute for Zoo and Wildlife Research showed that bats killed by German turbines may have come from places 1,000 or more miles away. This would suggest that German turbines — which an earlier study claims kill more than 200,000 bats a year — may be depressing populations across the entire northeastern portion of Europe. Some studies in the US have put the death toll as high as 70 bats per installed megawatt per year: with 40,000 MW of turbines currently installed in the US and Canada. This would give an annual death toll of up to three -million.
Why is the public not more aware of this carnage? First, because the wind industry (with the shameful complicity of some ornithological organisations) has gone to great trouble to cover it up — to the extent of burying the corpses of victims. Second, because the ongoing obsession with climate change means that many environmentalists are turning a blind eye to the ecological costs of renewable energy. What they clearly don’t appreciate — for they know next to nothing about biology — is that most of the species they claim are threatened by ‘climate change’ have already survived 10 to 20 ice ages, and sea-level rises far more dramatic than any we have experienced in recent millennia or expect in the next few centuries. Climate change won’t drive those species to extinction; well-meaning environmentalists might.
