On one hand many countries will invest in heavy industry, manufacturing, and fall back to fossil fuels.
On the other hand, economy overall should slow down and consumption of non-essential goods and services will drop.
I’m not expecting any definite answers or numbers, of course, just some food for thought.
There are hybrids, even in WWI there were French tanks with hybrid drivetrains, then WWII Germans also had super-heavy stuff with hybrid engines, and the AbramsX is supposed to also be like that.
