I hope and pray that in solving the problems, that we recognize that there is an opportunity not to be wasted. By that I mean that we do not simply rebuild the old technology and infrastructure that has been destroyed, but look to technologies that can provide the same, or better, services that were there before, but also provide greater reliability/"robustness" to disruptions in the future. What are those technologies? I don't know, but one thing that is clear to me is that power generation needs to be more widely distributed, as opposed to our very centralized system that we have now. IMO, long transmission lines are a vulnerability that we should start to be eliminating our dependence on.
