How wind trubines kill bats

If they make them in the form of "The Cross", that might keep the big ones away.

Seriously, who would have thought.

I wonder if they've tried 'deer whistles' on the blades?

Isen't this the same issue as birds being hit by the blades.

It's not that hard to believe these flying things being hit by the blades whose tips move at about 200 MPH.
 
Right; they don't have any predators that fast. Even the ones who've learned about cars are not prepared for that kind of speed, especially with no significant noise signature.

this must be akin to a wind shear for birds and bats, they don't know it until it is too late to avoid a collision

Interesting. Although, anyone could have thought of that solution.

What solution was that?

'deer whistles' I think.

I think the effect would be like a speeding car that keeps honking it horn. You can't hear the horn till it's to late.

 
The one in the article...

Cranky: Did you even read the article? Doesn't sound like you did.
 
The Royal Society for the Protection of Birds has apparently offered to be more accomodating to wind turbines, if they will cooperate in locating turbines away from critical birding areas. Here,

Regarding the latest news, it remains to be seen what the Royal Society for the Protection of Bats' position is on this matter.

Deaths of birds and/or bats should always be considered in relation to other factors that kill them:
Denmark studies this in 2001 (there are hundreds of giant windmills in that tiny country):

Windmills: 30,000
Automobies: 1,000,000
Cats: 55,000,000

If it were up to me, we could ban cats, instead!

It appears to be standard practice amongst those types of studies to normalize death rates attributable to one particular factor with all other known factors.

I hope you get along well with mice.

Wind turbines are killing raptors which are far less likely to be affected by cars or cats.
Plus there are far fewer raptors than sparrows.
It isn't enough to simply post the numbers.

"It isn't enough to simply post the numbers".
I believe there is paper work also with each one.

This is a simular issue with power lines.

So why can't we just help nature replace the lost raptors? Or even bats?
We do it with fish, and endangered species.
 
If it was your family, I'm not so sure you'd be happy with that strategy.

They need to be virtually extinct first. e.g. beavers and wolves proposed to be re-introduced to the UK. It is probably easier to protect and preserve than it is to re-introduce, especially if their niche has been closed or taken over.

I am very happy with the return of red kites (some sheep farmers not so happy) to parts of Wales. Never mind wind turbines, their survival has been difficult as they are vulnerable to unhappy farmers shooting or poisoning even now they are protected. When populations are at risk, just a few extra mortalities can trip the population over the edge.
Unliek song-bird or scavenger populations, raptor populations are much smaller as might be expected and thus more vulnerable.

JMW
 
So we breed fish because they are endangered? Or because we want to have fun with them?

Yes reducing the number of bat or raptor deaths is desirable, but as I pointed out there are alternitives to keep the species viable.

If you consiter the life time length of the wind turban, probally about 15 years, which is short in natures scheme. So we only need to worry about it for this cause for this time period.
However, the question remains, what will happen to the wind farms after there life? Will they be abandon, destroyed, or life extended?
So how long will be required to sustain these species?
