You can't, it was an order of magnitude napkin math calculation I did based on the cost of pump back hydro dams in china and the amount of energy storage you would need.
It is going to be in the trillions barring some radical revolution in storage that is unlikely given our breadth of knowledge of physics at this point. A lot of people think that Tesla Megapacks here and there are enough but those cover interruptions on the scale of minutes, not hours or days.
