This statement is 100% correct, but I think is wrong - utility scale solar is 100% more efficient and cheaper to build at scale, the problem is finding large parcels of land to put it on that are close to where the power consumption is, as well as the complexity and cost associated with grid interconnection (and transition if it not close to demand)

Edit: though if we ever get to self driving cars there should be a whole lot of parking lots in metro areas that aren’t needed.
