Did I post the Jeremy Rifkin lecture here yet? Watch it on 1.5 speed to save time. He outlines the infrastrucure shifts needed worldwide for a new, more efficient society.

Very optimistic and inspiring. But he only briefly alluded to the relationship of energy and economy by stating that a crash is coming when oil prices go over $120 and skipped past it.
.
I agree that we need to move to an internet of things sharing economy world wide. But it takes energy to make the transition so we need to stop all superfluous human activities and focus our remaining fossil fuel wealth to get as much done as possible before oil starts to slip away. It will leave us before we are ready to leave it. Along with many other peaking non renewable resources.
.
He also (deliberately?) leaves out any concept of scale and density of rebuildable solar and wind compared to the amount of energy we are using now.
.
So I agree we should strive for his vision with full dedication of remaining resources but also be ready with a simpler "Plan B" for the times when the techno solution falters over the inevitable speed bumps.
