If you go with a mixed solution like micro-nukes for the cities and the solar/batt option for the rich suburbs and rural, you are closer to a plausible total solution.  You wouldn't need such a vast expansion of the high voltage transmission lines that would take so much copper and aluminum and faces so many regulatory hurdles and shortage of manpower to build it and maintain it.

In this solution, suburbia would be limited to the rich while poor folks live in the cities with electricity, or in rural areas mostly without it.  The filthy rich would have the luxury skyscrapers for their city home and an off grid solar and wind powered rural estate in the countryside.  Basically the same organization as Jolly Old England circa 1880 when the Earl had his Estate and his London Town home.  Poor folks lived in squalor in the city or shacks on the estate to mind  the Lord's pigs and sheep.  The Manor got wired up for electricity in the 1920s, but the poor folks didn't start getting wired until after WWII.

I of course am no big fan of Nuke Puke, micro or otherwise, but this solution is at least plausible.  Not sure how much or how many of these micro nukes you would need to pull it off or how much it would cost, but it doesn't stretch my credibility like expanding and upgrading the grid does.  I am also unsure of how much Uranium this would require and whether enough can be mined up and refined, or how long it would take to build all these nukes if you started today.  I suspect it's a decade at least, probably 2.  Also don't know if enough nuclear power plant engineers could be trained up to staff them all.   Finally, the radioactive waste problem still remains.

The micro nuke solution also faces the same MONEY problem a grid build out does, which is that it is fabulously expensive and financing it with loans from already insolvent banks handed out to already insolvent construction companies with no clear idea how this debt could ever be paid by an increasingly poor population of consumers is a fiduciary magic act that is beyond my pay grade.

Regardless what solution is pursued here, I don't think any will come online fast enough to transition to the EV transport fleet with zero carbon by 2035.  As an increasing number of EVs get produced, the increased load will lead to more grid failures, blackouts and brownouts, or they will start rationing electricity.  I took a WAG that it will take about 5 years for this to become apparent.  Always risky to make predictions of course.
