History does show that renewable technology tends to develop when it is economically efficient. Alternatives to fossil fuels will be found when fossil fuels are too expensive to buy, and therefore people are willing to buy what is initially an inferior product. It is only then after general adoption, that the inferior product will improve to the point at which it is equal to the product it is replacing.  The fact is that as long as there are large scale supplies of fossil fuels available, and those supplies are plentiful enough to be affordable, consumers will be unwilling to accept the inferior performance they will get from electric cars, or the inferior comfort of smaller vehicles. The EU, with a far superior public transportation system is a bad comparison with the United States, as it is likely that the price at which Americans would accept the same sort of compromises is much higher, and no amount of environmental concern or preaching about alternative energy will generate the political capital to force them to if they don’t have to.  Furthermore, what the opposition ignores in this argument is that it is often the poor who will suffer the most from artificially high fuel prices. Raising prices will increasingly make driving a luxury good, limiting the mobility of low income workers. This will both reduce their standard of living (i.e. ability to take vacations) and reduce their options for work and therefore for advancement.
