Here in the West they're just covering up all the desert areas that are not being used anyways. And they also bring in livestock of various kinds to take care of a lot of the weeds and keep it cleaned up as well. I think it's a great use of space since there is so much of it in such wide abundance of sun. There's also quite a few of the car parks here that have been installing solar panels over the cars and that's a great use as well but that's also quite a huge expense overall.
