energy consumption. it s supply/demand economics. are those demand numbers sustainable? will it stay that way or is this a fluke right now? good question willie. nobody knows because nobody predicted this drop. i think the conventional wisdom is demand will continue to grow slowly but supply at least for the moment is also going to grow and we re probably looking at one or two-year phenomenon like this. in washington, it s gotten people talking about the gas tax. the gas tax has not been raised since 1993. highway trust fund is about to run out of money again for the third time in a number of years. you can see that spending on roads and mass transit has been going up. that s this red line here. but the revenues which is the dotted blue line from the gas tax, have been flat to down because people are driving less. they are using more fuel efficient cars.
