The world is nowhere near being in a position to replace the underlying forms of energy with another, augment at best. Reference this graph:

There isn't enough lithium and copper in the world to do this.
The direction I would go is small modular reactors with TRISO fuel that is accident safe. Use smaller, scalable power generation to produce hydrogen and electricity locally. Japan is still head long into fuel cell vehicles vs lithium and storage. The 12 years to build a full scale pressurized water nuke plant is too costly and slow for most utilities to get behind.
The energy from all this electrification must come from somewhere and renewables don't even scratch the surface.
