Once energy costs reach high enough people will embrace nuclear, hydrogen powered cars and more wind and solar.
Peak oil is peak of sweet light crude. It is not peak of all oil let alone energy sources.
Add in uranium breeder reactors, thorium salt reactors and micro reactors to supply base energy levels. Then add in high energy batteries to make the best use of sporadic wind and solar and you have plenty of viable alternatives.
The country that will best increase it's standard of living will be the one that can make best use of energy sources and farmland.
BTW USA has lots of fresh water... That is a huge advantage that is so often under estimated. Essentially USA and Australia are the same size countries. Australia has plenty of resources except not enough water.
