collapse of the old society

Exactly. Because oil in the ground is profit wasted. The energy companies want to transition the world to green energy - from giant nuclear power plants and wind farms and other centralized megastructures that they control and profit from - but not until the last drop of reasonably extractable fossil fuel has been sold and burned. So they pretend to be working on the "transition" now, and leech billions in government funding, while doing their best to slow the transition until they're ready to profit from it.
