Technology?

That sure does move back that "third world slag heap" you were predicting, doesn't it.
Moreover, there are considerable reserves in Canada stored in oil shales. Our technology continues to improve with respect to not only recovering oil but also in locating it.
Please contact your pals at the Club of Rome to learn how and why technology will let us down. Again. Luddites like them and you are not to be believed. They've/you've been so wrong so many times in the past, why should they/you be believed now?
I find your blind faith in future technology as a way to defeat the laws of physics quite amusing.
Lets get a few things straight: Coal and Oil are NON-RENEWABLE. Meaning when you use them, they're gone.
Still with me? Good.
So, when you use non-renewable resources they're eventually going to run out. If you're almost completely dependent upon said non-renewable resource for almost every aspect of your life and suddenly said resource RUNS OUT, well then you're pretty fucked.
Technology is NOT going to make non-renewable resources renewable. Renewable sources of energy may help with the issue but I personally have serious doubts that they will completely displace fossil fuels. I have some hope in nuclear fusion, but that's just about it.
Look up the "Impossible Hamster" to get a better visualization of the dilemma you're simply ignoring. Technology will not allow for indefinite, exponential human growth. It's a PHYSICAL LAW. Granted, this thread isn't discussing human growth specifically but simply doing nothing regarding our society's interdependence on oil only exacerbates the problem.
Also, about that shale in Canada. The EROI on any type of oil shale is very low. When I say very low, I mean VERY LOW. Anywhere from 1.7:1 - 2.1:1
Oil Shale is, at best, a MARGINAL resource. It is nearly impossible to rely on it: really a resource needs an EROI of 3:1 to be of real practical use. Corn-based Ethanol has an EROI of about 1:1 and is thus completely worthless. Oil in America when first discovered had an EROI of about 100:1 for some perspective.
So yes, they may be a lot more oil out there but most of it is NOT WORTH EXTRACTING. In accordance with the "Best First" principle our best, most profitable oil reserves have been or will be depleted. Whats left when all is said and done is, indeed, a lot of unused oil worldwide, but would incur a loss to extract.

Um what is EROI?
Other then that i get it, an example would be slovenias oil we used to extract it and there is still lots left tough for some reason nobody wants to do it anymore because there is no profit in it or was no profit do to the increase in oil prices maybe someone will start again.
EROI is an acronym for "Energy Return on Investment". Some people prefer EROEI (Energy Return on Energy Investment) but its pretty much the same thing. It's how much energy you get out of an energy source versus how much energy you needed to put into it in order to extract that much. EROI of 3:1 means you get 3 barrels of oil out of a well for every 1 barrel expended to extract, process, and transport it (the sum of all the energy used in order to get it to your gas station, power plant, etc). The units aren't always barrels of oil but it works as an example.
