The problem is its actual history.
Windmills did kill way too many birds
- when they first built at Altamont pass, a natural constriction on a major migratory bird route
- when they used open lattice towers, which present tons of tempting roosting spots
- seems like at least one more major factor.
But this was in like the 1970s and they paid attention. Since then, wind turbines kill effectively zero birds, but it’s a huge problem when there’s an actual grain of truth that conservatives can grab onto and never let go
Edit: apparently still in production despite the poor site, but it looks like they cut bird fatalities in half and are looking at newer turbine designs to be safer. I guess the real lesson is don’t build in a mountain pass constricting a major Migratory bird route
