>>I assume after a disaster we would massively increase the rate of production There is a chicken-egg problem here. You can't massively increase production because, you don't have enough energy to do that. And that is because your existing infrastructure is fried. For a few months/years at least you will have to bootstrap a lot of transformers to increase supply to produce more transformers. And only when you break even on a good enough energy you will go back to the normal. However note, in order to increase production you also need to mine quickly for you don't really have energy. So there are a lot of sub dependencies. But by any measure lack of energy for a such a long time, would have already set back world economy to way back in the past.
