It makes a lot of sense to me that PV and wind power could have subtle undesirable effects that we don't know about until it scales up.
Taking gigawatts of energy out of the planet ecology and redirecting it to something else seems like it could have drawbacks. Of course, on net it seems likely to still be a significant improvement over burning hydrocarbons.
