Bringing over the discussion from
Pops' Pearl Harbor Thread:

Yes, I am aware of that. However, that just goes to show that alternatives like tar sands and NGL can scale up and compensate for peak oil -- something which was said to be impossible by the peak oilers.
You write as though that's the final word. Unconventional and stocks have "scaled up" for the last couple of years, so they can continue to substitute for the decline in crude oil, and raise overall production for ever. Do you honestly think that?
Of course I don't think they can raise overall production forever. But there's no need for them to do that. You are pointlessly exaggerating the need for liquid fuel. There is no need for endless supplies of gasoline etc. In fact, we don't even need most of what we are using now. You could easily lop off 5mbd of U.S. oil consumption simply by people riding scooters/mopeds and carpooling. And that's with no loss of functionality whatsoever. The greatest users of oil are private automobiles, and most private auto use is optional/lifestyle-related, not necessary. So the inability to continually increase liquids production is not a problem. We have more than enough fuel to get everyone/everything from point A to point B. Do you disagree?
All liquids really need to do is hang in there long enough to allow further shifting to electric cars/scooters/bikes, electric trucks, electrified rail etc. That should be feasible because EVs are taking off right now, and Laherrere (of ASPO) predicts peak liquids for 2020.
Laherrere: "I have access to several technical databases.
Liquids production will significantly decline after a likely bumpy plateau 2010-2020 and likely chaotic oil prices.
30 years from now, production of easy oil will be 35% less than to day but production of all liquids (including from coal and biomass) only 5% less than to day."
Source (pdf)There will also be significant shifting to NG as a transportation fuel because NG supplies outside of North America remain plentiful and are not peaking.
When liquids peak, these alternatives (EVs and NG powered vehicles) will compensate for the decline, just as liquids are compensating for oil right now.
$this->bbcode_second_pass_quote('TonyPrep', '')$this->bbcode_second_pass_quote('JohnDenver', 'R')emember, the peak oiler claim has always been that *oil* is special and cannot be substituted with alternatives. That's why peak oil is so scary. The idea that liquids would smoothly substitute for oil has always been the cornucopian position.
And still is. Some of the unconventionals, as I understand NGLs, are an artifact of declining conventional reservoirs.
