Retrenching the dollar is impossible without the US government regaining control over the power of the mint-- something that's impossible. The 'federal' reserve isn't Federal, and has no reserves.

Yes. A gold/silver standard would stem the fiat currency inflation problem; it would also make the status quo fractional reserve banking impossible. Therefore, it will never happen.

I expect a push to Digital Central Bank Currencies tied to social credit systems; a boot stamping the face of the poor, forever.

But also consider at some point a technology will be more efficient than oil

It's already come and been abandoned: Nuclear fission.

I see the elites opting to build solar & wind infrastructure to monopolize after oil peaks. They'd rather rule over the ruins than lose control of the future.

I'd propose using nuclear as the spearhead of a transition to a hydrolysis/liquid hydrogen infrastructure, which could bridge into superconductors and a supergrid. I imagine liquid hydrogen pipelines cooling superconductors being a prerequisite for some future fusion technology becoming feasible as a primary energy source for the planet.

That kind of planning requires planning 7 generations ahead and our 'elites' are more concerned with lining their pockets and visiting Little St. James-style hedonistic theme-parks.
