Oil will never run out in our lifetime. The green River formation in the us alone has 3 trillion barrels worth of shale oil with half expected to be recoverable. At 100 million barrels of oil usage per day for the globe, it could support the world's oil usage by itself for over 40 years. Factor in all of the other resources, and it will be a long time before we run out.
