Solar, wind, carbon burning, nuclear, hydro… a mix. Petro fuel burning won't go away, it will just be a smaller part of the mix.
And there's plenty of capacity at night. And there are batteries, which we can charge with for example solar in the daytime, and then use at night.
Rooftop solar is great because it's near the point of use. All the people wringing their hands about the grid can rest easy, it will be fine. Sure in some climate solar is less available; see above… it can be a mix as appropriate for the place.
According to [1] in 2019 61% of the world electricity is produced burning coal and oil. I don't see a reason why this proportion would change to fullfill EV caused demand increase. I'm afraid that even worse - sweeping demand increase will be fullfilled the easiest way - burning oil and gas. Hydro and nuclear are slow to build. Solar... I don't know what is wrong with it but taking into account that it is a lot cheaper to extract (comparing to oil and gas) it is still just 3%.

ok, but others do.
The current landscape is just that, current. We can build new stuff. I agree there are challenges with speed and scale though. I don’t think they are completely insurmountable.
