If anyone is curious as to why we don't run the world off solar, from what I understand the big issue is power grid frequency. Unlike a turbine, solar has no intertia. If you take away light the power drop is instant. With turbines, they keep spinning due to their weight. This is especially important since if a large load is suddenly energized, the turbine might slow down but still won't stop immediately. Maybe in the future giant electric powered flywheels or pumpgen systems can take up the slack. Nuclear would likely also help since those are essentially giant steam turbine generators. Good video with some more info here.
