I think we are severely overestimating the panacea that is the future. When we run out of gas to fuel automobiles and natural gas to make fertilizer from, it will make us all poorer. Our problem is not just that we need to transition to electric automobiles or sustainable agriculture, rather it's that we have no replacement for the free portable liquid and gas energy that we take out of the ground every day.

We'd be better off planning for the reduction in carrying capacity of the human race that will ensue as fossil fuels wane, instead of trying to find more efficient ways to distribute all of our newfound wealth and production.
