Mitä linkkisi todistaa? Sen, että pumpattava öljy on paljon halvempaa tällä hetkellä, joten öljyä ei kannata tuottaa esim. liuskeöljystä? Kysymys oli potentiaalista, jos tarve vaatii eikä mikä on tällä hetkellä taloudellisesti kannattavaa.
"Fig 5 shows that half of US crude imports come from Mexico and Canada. As US crude production growth has stalled, North America could only become self sufficient in crude oil by replacing the other half of crude imports i.e. increasing imports of liquids from Canadian tar sands by a theoretical 2.8 mb/d, assuming Mexico could continue to export 700 kb/d. If these exports were to shrink by the past rate of 100 kb/d pa, the additional tar sand import requirement would be 3.5 mb/d in 7 years provided US oil consumption would not change. This calculation is theoretical because refineries usually need a blend of different types of crudes, not just heavy oil from Canada. So there would be a minimum crude import requirement from outside North America. And Canada itself also imports around 300 kb/d from outside North America.
In any case, an increasing reliance on tar sands would be an environmental and climate disaster."
The myth of US self-sufficiency in crude oil
Tämän voi kai halutessaan kumota: Barack Obama bans oil and gas drilling in most of Arctic and Atlantic oceans, joten on myös mahdollista nostaa pumpattavan öljyn määrää tarpeen sitä vaatiessa.
