People here also can calculate Pearson's coefficient between GDP and energy usage and understand by themselves that this is bullshit and that energy efficiency is less than minor in the grand scheme of things.

And those who did not brush up their math know about the theorical max efficiency of Carnot engines and can evaluate without calculation how much growth must be driven by efficiency increase and how much is driven by energy use increase. I mean, we did increase oil production by roughly 2-3 percent per year. If Carnot engines efficiency had risen as much as growth in the last 50 years, we would have those infinite energy motors...

And there is probably a lot of other way to reach that conclusion without thinking about it. I don't understand why people don't just think about it.
