I mean something undeniably WILL happen as the world has roughly 47 years left at current consumption rate of oil.
Whether what's going to happen will be whatever it is you're imagining is completely different story entirely.
Needless to say, If you have a largely deindustrialized country you can't really make any sort of transition happen yourself anyway, not at the grand scale and speed necessary for this endeavour.
Does that make those 47 years irrelevant - just because they will end?
There's no contradiction there. It just makes these last-remaining fossil fuels even more valuable.
Moreover oil use hasn't ramped down, nor is it getting replaced in any substantial way. I suspect people have no slightest clue just how reliant the modern world is on fossil fuels outside of it's use in cars.

Expect fireworks.
