The will to build the PV farms and the electrical wiring across the entire planet to always get the power where it's needed IS NOT THERE. The entire eletrical needs for the entire planet was meetable with some rather small area shown on a map in the Saharan desert. Panels have gained quite a significant efficiency jump since then so that total area has shrank. Again, they won't build the plants and they won't build the rest of the interconnects, though many countries already share electrical grids. It's fucking ridicules.
