$this->bbcode_second_pass_quote('garyp', '-') There is no mention of other approaches to the transportation problem, including ethanol, nuclear/electric, bikes, etc. There is probably a reason why they were told to do this, but it does reduce the usefulness significantly.
Perhaps they considered the possibilities and determined that they weren't viable.
Ethanol - low EROEI, displaces food production, ignores Ogallala aquifer depletion impact.
Nuclear/Electric - Each transformation of energy tends to lose part. Can the electric grid support millions of electric cars charging? What would the efficiency be?
Bikes - on a lovely spring day, that's a great idea. In the middle of a Texas summer or a North Dakota winter, they might be problematic. And they probably wouldn't be effective for transportation of goods.
