I don't want to go offtopic for too long, but the way I see it is not a matter of "sooner or later", it's a matter of "soon or we're screwed later". If we only act when oil prices are exorbitant, at that point there's no time or energy to update the energy infrastructure. PS: Oil will still exist, it's just that it may be too expensive to extract. Soon thereafter it may become energetically not worth it (i.e. it would require more energy to extract it than the energy recovered from it).

You got that right. Once all of the easy-to-obtain oil is gathered up, all that's left is oil-shale. While there is a lot of it (especially in the US) it is by far the hardest to extract like you said. It would be nice if it was easy to get, since it would be an abundant alternative resource to be inplemented until we get used to renewable resources like wind, solar, etc.
