Peak oil isn't just a "Government Theory" btw. The oil companies charts show the same info. Thus is the reason they have reported they'll most likely have decreased production of crude within the next 20-30 years, possibly farther out considering some of the reserves recently found, but also see an increase in many of the alternative fuels. That's directly from the oil companies (who aren't really evil, they're just doing what they're supposed to do, supply oil and make money).

Feel free to check out David O'Rielly's words "Most of the debate about whether peak oil is imminent, however, misses the point. Oil will peak - that is a geologic fact. But the new energy equation is not static. It is dynamic and variable."

Also George Kirkland's Statements "This view is based on the fact that technology will deliver conventional resources from new frontiers, like the Arctic, in addition to unconventional sources of energy - liquefied natural gas, gas-to-liquids, extra heavy oil, oil sands, among others - that will step in to fill the gap. In fact, by 2025 estimates are that nonconventional sources will account for roughly 10 percent of the global oil supply."

Other links are available at Chevron's site. Lots of links that actually have good legitimate information. If one chooses there are also sources that are available beyond Chevron's site that have 3rd party scientific research that backs up many of their views.

The real facet though isn't not using oil, it's a good energy source. They key is to make its usage CLEAN. I.E. Like the increase of ULEV type vehicles that basically produce no carbon waste; Prius, Insight, Sentra, Civic, and others.
