The chart above shows weekly US oil consumption since 2000 as the blue curve (the EIA weekly product supplied series). I have added a 13 week centered moving average (red) to cut the noise a bit. Both of these are on the left scale in millions of barrels/day (not zero-scaled to better show changes). Then the green curve is Brent oil price (right scale).
There's a couple of points worth making here. I have a very rough rule of thumb -- now that we are on the oil plateau -- that if US consumption is increasing, oil prices are below the required level. US consumption must decrease overall to accomodate rising consumption in the developing world, and stagnant supply. Since the beginning of 2011, oil consumption has been decreasing, suggesting that oil prices are in roughly the right range.
However, it's also worth noting that the price required to make consumption decline has increased over time. In 2006-2007, prices of around $70 were enough to make oil consumption flatten and then decline. However, in late 2009 and 2010, similar prices obtained while consumption continued to rise. It took the rise to over $100 in spring 2011 to get consumption to start to decline again.
Thus it seems likely that at some point, higher prices will be required to get US consumption to continue to decline. As usual, timing is hard to determine.
