This is speculation on my part, but I would think that the threat to the oil producers is not that they may run out of the stuff in 100 years...rather, it&#x27;s that oil may become obsolete before then (because alternative energy). At $30&#x2F;barrel, it puts tremendous pressure on electric cars, solar, wind, etc. At $100+&#x2F;barrel, they were creating a major incentive for the alternatives to thrive.<p>I&#x27;d like to hear about this from anyone more qualified than me (which would really be anyone).
