Do you mean the death of birds due to wind turbines? As best as I can tell, that is dwarfed by the birds killed by domesticated animals.
Or to apples to apples it killed by coal for that matter. It is a bizzare mental blindspot that people never ask that question - but birds always seem to come up mainly as NIMBY pretexts anyway.
you say "domesticated animals" but is that not cats exclusively?
The impact on the environment is severe in many aspects. The impact on the power grid as well. Germany already have to pay other countries to accept Germany's excess electricity in the other countries's power grids.
