demand has increased i don't have the exact figures, but, take a look at a chart between the usd and the px of a barrell of oil, seems to me that as the dollar drops as it has been for the last number of years the per barrell price of oil has increased - there is a direct corelation to a weak dollar leading to higher oil prices - when the foreigners sell us there oil they get paid in usd. if the usd is falling the only way to cover their losses on the usd is to raise the prices per barrell that with demanded outpacing supply pushes the price higher -
