We agree renewables are never likely to replace energy needs. Nuclear can and will once the anti-nuclear fools get out of the way. Smaller, mass produced reactor units are likely the way once we decide to make them. While more expensive in kWhr/$ metrics are reconsidered given other advantages, they offer a way past the overuse of fossil energy reserving it for critical applications. All of that assumes that nations develop rational energy policy not dominated by the climate mafia.

The EV of the future is much more likely to be based on Hydrogen with an awful lot of needed new technology. As you note we are nowhere near the ability to produce high density batteries for all those dream EVs that the government promotes. Utility scale batteries are a different proposition because they don't require the energy density. An interesting future involves home solar with those type of batteries.

As I note technology has always defeated Mathusian concepts and will continue to do so given past history.
