There are few issues I think nobody want to accept:
- living on renewable is possible in some parts of the inhabited earth, not all, essentially only where Sunlight + climate and|or hydro can be used enough for local residential needs;
- it's doable ONLY for private homes, not for industries, or so to speak actual "RE" tech can't be built with itself;
- it's doable only for few humans, not all those living already or relocatable toward eligible lands, starting from only those who can afford it.
Now if you start telling people: "you can have $thing, you, you and you can't" those excluded start to revolt if such $thing is a key to mere living/living well enough. So someone have probably thought "well, we can push most in situations they can't revolt, to survive they can only accept" and that the mechanic of "universal revenues" etc in a prisons-alike "smart cities" (so dumb citizens) like those from https://youtu.be/Hx3DhoLFO4s https://youtu.be/Hx3DhoLFO4s those who can are also divided in two cohort, the rebels witch can perhaps just barely survive and those who are helpful who can profit A BIT, but not more than that of the new society.
Are you think that's a crazy far-right stanza? Well, I came from a WWII Partisans family, so hardly nazi-fascist or clerical. BEVs have a handful of scale issue:
- current substantial inability of recycling batteries and perhaps producing enough of them;
- battery wight and stored energy limit that makes them substantially unfit for anything more than private cars, to a point that electrified roads would cost FAR LESS;
- to charge quickly, but really quickly, they simply drain to much power witch is not an issue per se, but is a AC distribution network stability issue since they cause a sudden frequency drop anytime they start draining power. Such drop can't be sustained on scale. It can be correct with "smart-grid" features who mount and lower the load slowly enough to allow power plants to adapt but so far no such feature exists;
- even really quick (300+ kW) chargers are not quick enough for long business trips, they can be ok only if you are on vacation, while the sole reasonable charging (from the Sun, locally generated electricity from a p.v. plant or hydro) hardly mach the current state of things.
To correct IMVHO:
- start mandate p.v. near-zero injection to the grid (allow just 1-3kW) to REDUCE grid frequency;
- start subsidizing SMALL (8-10kWh) home batteries, enough to offer the minimum except heating/cooling without the Sun to power a whole home (fridge, VMCs, computers, lights etc) with two purposes: compensating small p.v. output fluctuations and small blackouts;
- MANDATE home battery inverters high-voltage DC (400V) to DIRECTLY use (both directions) car battery for the home and to charge depending on p.v., no AC conversion needed;
- mandate domestic p.v., 10kWp minimum WITH subsides, to buy a BEV.
Those steps are the BARE minimum to get a sustainable amount of usable BEVs for those who can own/use them without causing grid issues. Oh surely, that means a far slower transition but ladies and gentleman transition will be slow ANYWAY because so far only possible at individual homes level, no technical way to "accelerate" at all beside a mass genocide.
