I shouldn’t have used the word “trend” – it’s more of a massive push toward alternative fuel. Capitalism at its best. The recent spike in the price of oil has only made the major auto manufacturers wake up to the fact that alternative fuel vehicles are their future income. They’ll be mainstream in a few years, let alone 2025. Those who want to keep a gasoline-powered weekend car (like me) and pay $20/gallon will happily do that, but commuters will not be driving them to work.
The transition from oil to alternative fuels in other industries may not be easy, but companies who want to compete will find a way. A technological disaster is much more likely than a Mad Max scenario due to peak oil. If you feel the need to worry about the end of days, you should be more concerned about nanobots turning the entire planet into jello, or a man-made plague.
