$this->bbcode_second_pass_quote('TonyPrep', 'M')ind you, I'm not convinced that some liquids are double counting, as Leanan asserts, since the inputs simply get added to the demand side.
But we're not talking about demand, we're talking about production. If you pump out 1 million barrels of oil and then use 500,000 of that to produce 1 million barrels of ethanol, how much have you really produced? The IEA would say 2 million. I would say you have traded 500,000 barrels of oil for 500,000 barrels of something else - so you really only produced 1.5 million total. (I'm making up these numbers, of course)
This goes back to the fact that EROEI is not accounted for. Ethanol is one of the more obvious culprits, but it has always taken some amount of energy to produce a barrel of oil. That amount is growing.
Having said all that, I skimmed the IEA report and it seemed to say that
crude oil production has increased 1.4mb/d. Does this not mean crude and condensates?
