I'll cast my vote for that one, too. It was one of those classic "Oh shit" moments for me this year.
Hard data like that give coments like Heinberg's "well connected insider" quote the weight they deserve.

That was a good one. Also vivid in my mind was the graph at the top of the "natural gas cliff" post. (I can't seem to get the current TOD search function to find it.) (Ah, here is it - found in a comment below. Direct link to the chart.)

Thanks to all the posters for their hard work. Engineer-Poets energy-scheme post stands in my mind as a monumental effort, even if I disagree with the conclusions... And the Sasquatch parable was good - I wish Nate would fix the minor flaws in the numbers and re-post it in a more permanent place.

Wish list for future posts:
* Inflation vs. deflation (not that we'll ever wrap up that debate),
* other topics in how money works in the international scene, and the interaction between that and peak oil
* current trends in EROI of fossil fuels, if anybody can find good data - I think that this is critical in evaluating the current apparent "plateau",
* more on the impact of low EROIs on economy and society. Why worry about whether ethanol is 0.9 vs. 1.3 if anything less than 4 is potentially useless?
