Oil companies make money from selling gasoline and diesel to owners of ICE cars. An EV's 'juice' comes out of a wall socket. Is there a similar direct relationship as the one between oil companies and car companies? Are electricity companies in fact major investors in for instance Tesla? If not, shouldn't they? What is the common interest between an EV builder like Tesla and an electricity company? How can they mutually enhance each others potential? Or is there a potential conflict of interests?
