This song of Oil running out has been playing constantly for the last 30 years. The reason you don't hear the "Peak Oil" song and narrative being played anymore by the propaganda agencies in America is because the globe has not even hit peak oil yet.
Global production of oil fell from a high point in 2005 at 74 mb/d, but has since rebounded setting new records in both 2011 and 2012.

You and I will have vehicles drinking Petroleum for at least 10 years. At that point there will be slow shifts to other fuel technologies.

- VandyILL 13y agoOne of the reasons the estimates for Peak Oil are off is because oil companies only project the amount of oil they can economically recover. However, because the price of oil continues to go up they start to consider more options economical, such as tar sands. If you read literature on how these companies determine the size of their reserves and how much oil is left that can be extracted economcally, the answer is pretty much consistent at 40 years, but this measure has never been an accurate account of the total amount of oil in the ground, its just a number that makes sense for their business.
- beat 13y agoIt stops when EROEI hits 1:1, though, and it's no longer possible to get a net positive energy result from recovery/refining. The tar sands are already in the 3:1 range. Corn ethanol is even worse, 1.3:1. In practice, it will stop before that, when the recovery costs exceed the cost of wind/solar. In the meantime, it will continue to be LESS expensive than unsubsidized wind/solar.
- danielweber 13y agoI'm not convinced that battery-powered vehicles are a better idea than using that same energy to manufacture fossil fuels from atmospheric CO2. We could be using gasoline in cars 100 years from now, only the gas is a storage mechanism for nuke/solar.
- beat 13y agoIt's a thermal efficiency problem. Yes, you can theoretically turn atmospheric gasses (CO2 and water) into gasoline, but it requires a LOT more energy to create than you get out of it by burning on the back end. If there's sufficient surplus solar energy one of these days, it's great. Gasoline is just about the perfect energy source for vehicles, but petroleum is kind of a nasty source for gasoline. Unfortunately, it's the only net energy positive one.
