The paint job might make the windmills more visible to humans and make people not want them on their land or within eyesight. This could lead to fewer being built and more dependence on fossil fuels which ultimately kill more birds.
And warmer blades might be less stiff, decreasing efficiency, and with it increasing birds killed/GWh (but that’s not even guessing from my side; I don’t know whether stiffness would be affected, and I don’t know whether it would affect efficiency, or in what direction)
I think that’s already the case. Better paint one black before someone has the idea to put ads on them, the only thing that could make them even less pleasant to have around
Do you actually live near an installation of wind turbines? I don't, but I drive past many wind farms fairly regularly. I just can't wrap my head around this "they're so unpleasant" argument. They are aesthetically neutral at worst.
Seems to be the outcome of existing bias that is entirely unrelated to the aesthetic "pleasantness" of the wind farms. Trotted out by politicians that have a vested interest in subsidising fossil fuels, whose extent of suffering through the unpleasantness of wind farms is looking down at them from 30,000 ft.
I also have a strong dislike for the aesthetic, though my wife doesn't mind it much, so I guess it's a purely subjective take. Assuming that everyone who disagrees with you is blindly shilling for politicians and oil companies is a bit extreme, though.
