California might have a decent amount of electricity from renewables, but it is nowhere near 70%. According to https://www.energy.ca.gov/data-repo...ty-data/2020-total-system-electric-generation it is closer to 45%. Even if you add nuclear, it only gets to about 55%.Irregardless of the energy density of gasoline, gasoline's energy has to be burned in an explosion to change the energy into a useful form of propulsion. Gas engines are usually only about 20%-25% efficient in producing useful energy, with 75%-80% of the energy wasted as heat...which causes global warming.
All of this wasted heat energy also requires gas cars to have large complicated cooling systems, to get rid of all this heat. All of this heat requires oil to lubricate parts, which then wears out from the heat, requiring replacement of oil and car parts.
Electric motors don't need to heat something to work, and are 90%-95% efficient. Gasoline is energy-dense, but hugely energy-wasteful. Electric motors don't damage the planet, and in states like California with 70% hydro-solar-wind generated power, generating the electricity is mostly non-polluting as well. Gas is a dead end.
