Hand-wringing about land use amounts to concern trolling. There is absolutely no hint of shortage of land to site overabundant solar on. Solar coexists synergetically with numerous existing uses, including reservoirs and canals, pastures and farmland, and on industrial, warehouse, and even residential roofs and parking lots. On water, solar farms operate more efficiently and cut evaporation and biofouling. In pasture and farmland, they operate more efficiently, cut water demand and heat stress, and for many crops even increase yield. They extend the life of roofs under and cars parked under them. The area now devoted to domestic oil extraction is well over the most that would ever be needed for overbuilt solar, even without dual use. Wind extraction, of course, has long coexisted nicely with agriculture and navigation. So, the most effective way to get the overabundant energy we will need is to overbuild renewables. The "environmental externalities" of renewable generation are orders of magnitude less than for others, so for purposes of planning really are negligible. Most of that is carbon emission occasioned by fabrication before the power used can be generated renewably.
