Electricity can be stored, mostly in pumped hydro storage, but also in e.g. battery storage, pressurized air or heated rock. But storage is scarce, expensive and doesn't look like it is going to be built anytime soon (for the usual reasons, NIMBY, environmentalism, YAGNI (correct or imagined), "energy abstinence is more virtuous", "we can manage by regulating demand", etc.)

Pumped hydro capacities are all but fully occupied, and few and far between to begin with. Battery tech os nowhere close, nor is battery capacity, to make as much as a dent overall.
