This reminds me of a comment about Creality's belted 3D printer not being able to violate the laws of physics and then someone added rollers so long prints don't fall of the bed...

You can do three easy things. Create bigger electricity grids with more decentralized generation (the whole earth receives a roughly constant amount of energy from the sun), overproduce energy or build some storage.
