This TED talk is funnily enough entirely spoken from a US-selfish point of view. The already old presentation (2005) makes a scientific-economical, peer-reviewed case to get entirely rid of oil dependence for transport in a couple of years time, without major governmental influence and actually gaining (American) jobs. Not that the barrel price back then was $26, not the $80+ range we’re seeing today. It is a compelling proposition, and what it did to me is showing at least the real feasibility. Having said that, there is still, 2.5 years later no way for me to buy a truly fuel efficient car (Toyota Prius) here unless I cough up at least $42.000, and that is NOT the sort of car this guy is talking about.
