The thing about a market like the oil market is that, in the short term, demand is inelastic. We need a certain amount of oil to function as a society, that amount is a function of many factors, most of them difficult to change in the short term. Most of us can't simply reduce our consumption at the spur of the moment, and it holds even more true for business users. Most of my oil consumption is through driving to work and various places around town. I can't not drive to work, given the sad lack of public transportation where I live, and I just got a new car, so I'm not going to rush out and buy one with better MPG (although mine is MUCH better than the average tank on the road today in that respect).
Given that, demand for oil is relativly inelastic for short term fluctuations. We all might bitch and moan, but changing our consumption patterns is too difficult in the short term. However, if the currently high prices persist, we'll see a HUGE shift away from our current wasteful oil consumption habits. Europe is a good model for this. If long term prices stay high, it gives the country incentive to develop ways to cut consumption, as the return will be seen over a long period of time. Public transit, always a low point in the vast majority of America, will become much closer to how it looks in Europe. More trains, subways and busses for short and long distance travel. We'll also drive smaller and more efficient vehicles. Again, Europe has SUVs, but they are enough of a rarity that seeing them is kind of a surprise, while in the US you can't go 10 feet without seeing one. I also suspect that the current pattern of suburban growth will reverse itself, as it becomes less economical to live out in the burbs and commute into the city. Of course I'm talking fairly long term here, but if oil prices stay high, we WILL see these things happen. Even longer term, oil alternatives will become much more of a hot button issue. Right now, oil is a good deal, and while alternative sources of energy are a scientificly interesting area, there is less economic incentive to persue them. When the economics make sense, we'll see a MASSIVE push in that field as well.
The idea that our current energy consumption patterns have nothing to do with prices is stupid, high prices will change them because low prices brought them about in the first place. The growth of suburban areas came about mostly because low fuel prices made it easy to live in the pseudo-country and work in the city. The SUV became popular because, although they are hugely wasteful vehicles, the relative costs were low enough to make them economical for many consumers. You can see the reversal aready, try and watch a car commercial today and see how many mention fuel economy. 6 years ago, I don't think that would have been much of a selling point.
