Another thing to keep in mind with solar is that so far we have been optimizing primarily for cost, rather than land use. This means installing panels at a high angle, far apart from each other to minimize shading and maximize energy captured per panel. If land is ever the limiting factor we can tilt solar panels at a shallower angle to reduce shading problems or just accept a certain amount of shading in the morning or evening. This could reduce land use by a factor of 5 or more.

I read a really interesting article about the rise of solar powered fish farms in China some years ago. These use aquaculture techniques with ponds shaded by solar cells, with feed grasses grown as part of the same mini ecosystem. I think there's a ton of open space for exploring how we could colocate solar, wind, and other land uses in a way that's mutually beneficial to each.
