39. The conclusion I have reached is electrification, both personal and freight
Electric cars, electric trains, electric trucks (trams). The part that cannot be electrified can be run on biofuel and a modest CTL program (< 1 Mbbl/dy total).

Electric cars (w/ regen braking) require 1/7th of the energy of an equivalent sized IC powered vehicle to get a payload from point A to B in typical driving conditions.

Parallel to transforming the transportation energy carrier, we need to transform society. In a general sense, re-localize. Much shorter commutes, essential goods and services produced locally as much as possible.

Problem is, we will still need personal transport to negotiate the sprawl built over generations during the transition that will take generations. The following class of vehicle is probably the future in this transition. Designed using bicycle concepts (the most efficient form of transportation), a small, lightweight EV.

People should probably not get their hopes up for anything bigger, as there are not the resources to build a fleet of EV's equal to the number of IC personal vehicles we have today.

Oh, and did you know that a conventional IC personal vehicle (say, a Ford Taurus) is more energy efficient than all forms of mass transit when the vehicle carries two or more passengers. From an energy conservation standpoint, small efficient EV's make much more sense than mass transit except for the most densely traveled routes.
