As I live not far from Altamont Pass and often hike the wind energy area, I see the damage windmill blades do to birds by the number of dead ones on the ground. Also, these windmills are truly Star Wars ugly and insulting to the environment visually, not even considering what they do to birds. Ugh, overall. Are wind turbines better energy producers, all things considered? With turbines, at least screens can be put on them, but as a naturalist I do understand that a bird hitting a screen in flight is almost as bad as hitting a blade. Both near 100% fatality, but even a few percentage points better saves birds. Turbines can be grouped closer and are perhaps more space efficient(?), and are not as architecturally offensive as I have actually seen some online that look sculpted and are quite cool. Are they less deceptive to flying birds with their unmoving support structure, as birds know to avoid the support structure but not the moving blades of a windmill? Thanks for any learned input.
