Peak Oil News and Message Boards

I was reading the article referenced at the landing page when I realized it also has a weakness. Internal combustion engines have room to become more efficient. They also have become more efficient in recent decades. All you have to do to realize this is look at an F-150, which I think is America's most popular vehicle, from the most recent model year and compare it to one from a couple of decades ago. The modern one is much larger. They have have the same hauling capacity. The efficiencies have gone into allowing the modern one to become that much bigger. Right away, you can see that huge gains could be made in terms of fuel efficiency by making something like that small again. Battery powered electric vehicles are facing their own efficiency challenges. They may compete well against the current fleet of bloated cars and trucks, but would they do so well against a leaner fleet? What about a leaner fleet that has had a lot more research money poured into fuel efficiency? I know, it's scary when you consider the environment. It would be nice to go all electric and really cut down on carbon emissions. The plus side, though, is that the people behind going all electric could have some concrete obstacles to overcome after which they would know better about how to really pull it off. Extending oil that bit more, with efficiency gains, might just give them the time they need.
