The hill in the photo looks ugly, tbh. Still, much better (and livelier) than the landscape after oilsands or brown coal extraction.
Preferably, most grid-connected solar panels would be on buildings, deserts, and postindustrial land. But in the face of the climate catastrophe, the South China hills are also fine.
I mean - one thing ugly, and the other thing is that this land could be arable or a nature reserve.
