It will not be long until renewable energy sources replace fossil fuels. I give it a maximum 30 years. You may say I am a dreamer. You may deem it impossible. But the more scientific progress continues to 'fuel' innovation in the 21st century, the farther away we drift from using oil and coal.

Considering how unreliable Venezuela's figures are, thanks to Chavez, Venezuela could be extracting oil for a lot longer than 200 years!

This doesn't account for oil sands in Canada, which would be around 170 billion barrels of reserves under current technologies.

Per this chart, China will run out of domestic oil in <10 years assuming no growth in current production rate & the US will run out of reserves in 11.3 years, again assuming no growth beyond 2010 production rates. Am I correct in thinking the two biggest users of oil will be 100% oil importers within the decade? Let's hope someone comes up with some new technology to get more oil out of the ground or $100 oil will seem very cheap & economic growth will be severly hampered.

Interesting that Venezuela's oil reserves are shown at 200 billion barrels (which are mostly very heavy crude), but Canada's reserves do not include the oil sands of almost as much and which are currently producing more oil than Venezuela!
