For electric power it’s an especially tricky physics problem; you can’t overproduce power, or things will just blow up. Grid operators must perfectly balance supply and demand at every moment of every day and electricity moves at the speed of light, so the electricity powering your lights was a hunk of coal or a gust of wind within the last nanosecond. large scale batteries could make the jobs of grid operators like me soo much easier.
