There is all the reason for the 30% increase, and that is only the beginning, $180 dollars / barrel of crude is fair price according to some well informed estimates. Could go much higher if and when the dollar collapses. It is important to understand why, because all politicians, from left to right understand that all American voters (except few Greens) share the same unsaid priority, to be delivered cheap fuel, and no sane politician can expect to win if he does not acknowledge that truism, and so the change must come from below, by getting rid of the denial that natural resources are limited. But notice also that yesterday Bernacke from the Federal Reserve confirmed that the situation is caused by supply-demand crunch, and before that Romano Prodi from the European Commission confirmed that the problem is structural. Hedge-funds and the rest of them and what possible role they play, they are the symptom, not the disease.
So here goes, first take a look at this picture:
That is the first part, the geological part of the Peok Oil theory (google Hubbert's peak for more info). The production capacity goes along Gaussian curve, and that is well established theory and proven right by numerous historical examples, e.g. US PO in 1970. PO has got nothing to do with running out of oil (that will never happen in absolute sense), and everything to do with the fact that global production capability will start to decrease by about yearly 3% quite soon. ASPO model, shown in the picture, is just one of many, but the disagreement for the PO date is not very big between various models, only few years, and the exact date is not really essential. What is essential is the next part.
So here we come to the second part of the PO theory, the socio-economical part. I assume the laws of supply and demand are familiar to you, and you understand what will happen to commodity prices when the demand surpasses supply, especially fysically limited supply? That is what is happening now, the supply can't satisfy the increasing global demand, as the physical limit has been more or less reached and we have now arrived at what is called PO production plateau. So up up goes the price. Next task is to start thinking what are the implications of PO spesifically for the US, which uses 25% of all the oil production in the world and twise as much per capita as Europeans, and the implications for the (nearly) global growth based socio-economic model, model that is based on the unquestioned assumption of unlimited natural resources.
It is not an easy task (should you give up denial and think it through) because giving up everything one has been raised up to believe is not an easy task for us human beings. First you will probably go through a phase of anxiety, nightmeres, hopelessness, all kinds of negative feelings, before (if you find the strength and compassion in yourself) you start to think what you can do on your part to push the odds towards avoiding the worst scenarios.
In the PO discussion forums I see that the reaction of many Americans is to get ready to "run to the hills", hoarding food, guns and ammo to defend their stash against the hungry crowd. That is suicidal reaction, it is based on prediction that can be self-fulfilling. I hope that is not the reaction of the good people on DU, but that together with others they will start to educate themselves, share information and look for solutions based on community and feeling of solidarity.
