When I posted about there being no need for higher fuel economy standards, I mentioned in a later comment how high gas prices do two things: alter people’s behavior when it comes to choice of vehicles, change how much they drive, etc and new resources become economically feasible. I mentioned the tar sands in Alberta, Canada as an example, this article talks about Shell’s work on recovering oil from oil shale. The size of those deposits is huge and until oil began rising to current levels, they didn’t make economic sense. Now they are looking a lot better.
Let the market and prices work their magic and supplies start to appear to take up the slack. If politicians try to interfere with talk of “price gouging” and laws to cap prices, then the market breaks and new alternatives can’t get a foothold.
