There have been no new refineries built in the US in thirty years. It is a NIMBY issue apparently but I suspect that is an excuse from the Oil companies. To believe that they don't have the clout to get a refinery built is silly. I notice that all the moves by the Bush admin regarding replacing oil are towards a similar distribution system or adjuncts to the current gasoline itself. Pretty muchly protecting their interests for sure. A better answer is solar conversion to electricity or solar conversion to hydrogen, the former is proven working technology and the second one seems to be coming online in a small way. Maybe the market place can defeat even big oil if they gouge too much.
