Actually a lot, especially at scale. Solar PV is not as bad but wind is a significant threat to hoary bats as a species and to large threatened birds like eagles, owls, etc. Yes cats kill 1000x more birds than current wind but they kill swallows and robins and stuff, not damned eagles. Mining and fabricating the amount of low-density energy harvesters and storage systems needed to fill in the intermittency also requires dozens of times more materials, land, and waste than the major carbon-free competition (nuclear).
