Electric is here to stay and will only increase its market share IMO. Legislation will see to that but in slightly bizarre twist off fate that same legislation will allow a certain number of ICE cars to be produced. See Porsche and their manufacturing right now. The only thing that will save the ICE is clean fuels, once again look a Porsche and their research into clean fuels.
As for not enough electric generation, that's poppycock and industry will provide (as is happening in Europe).
