Electrification of transportation as a response to peaking of world oil production
ttp://www.energybulletin.net/14492.html
The technology for electrification of transportation is extremely well proven and widely used (more so outside the US) and, from an energy BTU/joule point-of-view, highly efficient. Well-established modes of electrified transportation in use today provide many more freight ton-miles/BTU and passenger-miles per BTU than the competing rubber-tired, oil-burning transportation alternatives.
The ratio in energy efficiency is so great, especially when electrified rail is substituted for "18 wheeler" tractor trailers and single-occupancy vehicles (SOVs), that minimal, if any, expansion of the national electricity grid will be required to reduce U.S. national oil consumption by 10%, or about two million barrels per day.
Electrified transportation is also much more environmentally benign as well. Central power plants are more efficient thermodynamically and their emissions can be more easily controlled. Electric motors are dramatically more efficient than internal combustion engines.
There are three viable electrified modes available in the USA today: (1) urban rail – rapid/heavy rail, high-performance light rail transit (LRT), and streetcars, (2) electric trolleybuses, and (3) electrified inter-city railroad lines (predominantly freight, but with a passenger component).
The US could learn from the French "Grand Strategy" of using domestic nuclear and hydroelectric power to operate electrified inter-city transportation and urban rail. A majority of French towns of 250,000 or more are now getting at least one new tram line.
