I don't believe they are the sole reason at all. OPEC countries for example are using more and more oil and soon will combine to use more than OECD countries. But that's not the only thing. You have an increasingly global world, increased demand in the BRIC's and throw in dwindling crude reserves and more reliance on higher cost oil (like tar sands) what does it equal? All together now...High prices!
But hey i'm the one with no idea 
Yes, as has been shown throughout this thread, you ARE the one with no idea. Like 333 said, you Obama dicksuckers and your refusal to put any of this on your God-King is a sad, pathetic joke. For one, you refuse to acknowledge the failed fiscal policies of your Messiah that have contributed to 19+ weeks of increased oil prices. Secondly, trying to pin this on a "recovery" from the recession is another sad joke as there is no recovery. And there certainly wasn't any talk of recovery in November, when prices started going up. But you keep hanging onto your fantasy about demand, though.

I'd hate to rain on your parade but you really need to read into China's current economic situation. It's not roses like you think and their demand for oil is falling right now due to inflation's effects starting to him them hard. But hey, you go ahead and thump your chest about demand until you're blue in the face. Maybe if you draw blood it might come true.
