No combination of alternative fuels can or will ever replace the 160 exajoules of energy that industrial civilization currently consumes each year. Attempting to do so will result in ecological disaster. Thorium nuclear would get us near that again, but it's not likely to be something we do in the case of a complete industrial civilization collapse.
So what happens is that we "reboot" to a smaller scale civilization with a limited population. No matter what happens, there's still a lot of refined metal, particularly copper wire, laying around so we will probably have electricity no matter what. We also have plenty of mirrors that can be re-purposed for mini-smelting operations and water purification. Moreover, there will still be plenty of functional practical machines and devices. Cars will be a valuable source of alternators for electricity generation. Simple items, like stainless steel tables and bowls will last for hundreds of years. Steam is likely to make a comeback.
We won't reboot, and the population bottleneck from 2100 to 2200 may be quite severe, but some will survive and muddle through.
