Not too slow not too fast not changing direction not speeding up not slowing down and predictable enough that you know all that and a bit more before you build the thing and maybe your giant bird blender will pay for itself before it breaks down.,(reply>), @Ryvaken <br>And I'm not sure how you even came up with the stupid that is your claim about turbines in areas with low wind, and their energy output being a drain.<br><br>You could out a turbine in an area with so little wind that it produces 10 times less energy than average,  and it would still produce more than twice the energy that it took to make and install it.<br><br>And no one is going to put a turbine in an area with that little wind......<br>They don't guess at where they want to put these things. There's VERY few places on land that we don't have decades of wind data for.,(reply>), @Robert Pruitt A "lives lost per megawatt produced" calculation isn't possible because of how unreliable wind power is, even the ones that are positioned well enough to actually generate a positive return. Whatever merits you find in the top percentage of performance isn't repeatable. This is a technological dead end.,(reply>), @Robert Pruitt Can't help but notice you skipping over the far more important problem that a fair number of these things are net energy drains instead of producers.,(reply>), Fossil fuels directly kill over 4 million people worldwide every year, and they also cause 26 million people to die sooner due to making preexisting conditions worse. Only 55 million people die every year.<br><br>If fossil fuels are doing that to us, just how many animals, who mostly don't have any healthcare at all, do you think are being killed because of them?<br><br>Far far more. The fact is that even if wind turbines killed 10 times more birds, a LOT less birds would be killed compared to fossil fuels.<br><br>Take your ignorance somewhere else.<br><br>Also, between a 100 million and a billion birds are killed in America due to our buildings.
