The Organization for Petroleum Exporting Countries reports that there are 1.5 trillion barrels of crude oil reserves left in the world. These are proven reserves that are still capable of being extracted by commercial drilling. That figure (which is wildly debated) may seem like a lot (or maybe not), but consumption rates are growing year by year. The International Energy Agency says that the world uses 34 billion barrels of crude every year. The bottom line is that crude oil is a non-renewable resource. So, regardless of the exact quantity, the fact remains that the supply is dwindling more and more every day.
