Begs the question, why didn't the world wean off oil and supporting then-repressive regimes 50 years ago. I despair for the species sometimes.
But I could offer a concession, at the time, that the solutions were not off-the-shelf available.
Now? The bottom has fell out of the "we can't" argument. Solar just kept going down in price along with batteries. Anyone defending coal power is hardly doing so on the price argument. A solar-based economy is not familiar, no. We will have to build infrastructure that turns on and off daily and seasonally in response to electricity supply-and-demand balance. There are large engineering changes needed... but no cultural ones.
There's no day like today. The energy transition will benefit our friends and crush our enemies.
