It's running out pretty fast now, just a matter of time. 7% depletion per year, won't be long. I suggest buying petrol cars in Australia, because they can be converted to gas which is abundant here.
Newbie question: I assume the current economic crises is to blame for the recent decline in oil prices... But I thought if we are running out of oil and we depend on it so much wouldn't that drive prices higher? So you could expect prices to increase alot once demand picks up?
