Re: The elephant...
Problem is we keep finding unintended consequences from dabbling with nature. So I saw something about an island off Australia. Uninhabited, but in whaling waters. So people figured it was a good idea to stick some rabbits there, so there'd be some food around. Rabbits did as rabbits do, and then there were a lot of rabbits, and much less vegetation.
The transition to 'carbon-neutral' carries a lot of the same risks. There's a lot of pressure to do it, because there's a lot of money to be made. There's often much less concern about the environmental impact, even to the extent that allegedly pro-environment groups like Greenpeace or the RSPB encourage wind farms. I mean nothing says 'protecting the environment' quite like covering it in solar farms, and windmills.
So early wind installations, famously Altamont Pass in California killed a lot of birds, including heavily protected ones like Golden Eagles. The numbers of dead raptors have been dropping, which no doubt will be seen as a 'success' for ever larger 'bird friendly' windmills being built there now. And that 'success' will no doubt be used in PR, and local extinction will be glossed over.
And of course if you erase a predator, then their prey populations increase.. So unsuprisingly, ground squirrels support wind power.. Except those squirrels are a pest and will destroy vegatation, so habitat loss for other species..
Or windmills also kill lots of bats, which normally are a protected species. 'Renewables' get an exemption on that one. Bats help keep insect populations in check, but then so might windmills-
The model calculation used in the study indicates that the numbers of affected flying insects could be relevant for the stability of the flying insect population and thus influence species protection and the food chain.
The study does not conclude whether wind farms are the main cause of insect extinction or whether they have an impact on it.
Although the study did show plenty of bug impacts on windmill blades, leading to efficency losses and costs to try and keep those clean.
But there are impacts, either directly killing species, or indirect effects from things like boundary layer mixing & vorticies on species and habitats down-wind from massive windmills. So ok, some of these effects are easier to hide than eagle carcasses.. Like off-shore windfarms. But those have their own impacts from construction and potential threats like mechanical noise and vibration. LF sonar bad! LF noise from wind farms.. Let's gloss over that one and build MOAR!
Alternatively, given 'renewables' are the most expensive/less efficient and most environmentally harmful forms of electricity generation.. Perhaps building more nuclear plants is a better way to tackle the 'low carbon' problem.. Assuming of course that carbon is/was ever a problem..
