What you say is not true in most places. EV charging won't raise overall power consumption that much, and the majority of tthe EU will stop burning coal around the 2030's. Nuclear isn't much on the table in Europe, especially since new wind developments produce cheaper power than nuclear plants. Solar works quite well at lower latitudes, but at higher latitudes in Europe it can work as a supplement to hydro in the summer (as there's less water around then), but it won't play any significant role in power production (some 10s of percentage points perhaps). Biggest challenge for the next few decades is inertia as well as base load when there's low wind over large geographic areas. We need cheaper (and better) grid scale energy storage. A lot of people forget about the cheaper part.
