You can't burn it if you can't find it
Chart from the Association for the Study of Peak Oil and Gas
In that graph, the scales represent gigabarrels per year, averaged over the 10 years centered on the year on the bottom. What it shows is that the world is already using far more oil than is being discovered, even with the latest technology and high prices. While the reckless consumption can probably continue a little while longer on previously-discovered oil, all of that will be mostly gone relatively soon, and new discoveries aren't coming (and won't come) close to making up the difference. I can't understand why groups like the IEA continue to make absurd predictions like the one in the chart showing 45 gb/yr in 2030--there is no way at all that there will be that much oil available.
