$this->bbcode_second_pass_quote('yesplease', 'I') think I've seen the more false dichotomies from mods on this site than anywhere else.

Then please educate and enlighten.
I think that short-term momentum is not the same thing as a "proof" that a thing is true. Because something "works" for a short-period of time (measured in years in this case) does not mean that it will prove to be an accurate description of what is or is not possible. It only means that a model was not complex enough to predict the timing of the event (in this case GDP contraction).
Just because a model (declining global energy available = declining world GDP) is not complex enough to account for a delay between the onset of one and result does not mean that the model is fundamentally flawed; only that it is inadequately complex to account for the delay.

$this->bbcode_second_pass_quote('yesplease', 'I')s there some statistically significant disconnect between the two?
They may be. What does the consumption graph look like?
$this->bbcode_second_pass_quote('yesplease', 'F')air enough.
Average oil consumption was flat for a decade plus.
Big deal. you tried to give the impression that oil consumption was essentially flat for a decade. That would have been truly misleading, if not corrected.

Actually for the most part GDP/oil demand seem to track pretty well in terms of time, especially for the most significant events. It's a false dichotomy in that we don't have to choose between oil or a significant drop in GDP. We have data regarding whether or not oil demand is primarily influenced by GDP or the other way around and so far it seems like GDP drives oil for the most part, not the other way around, although they are intermingled so we do need a certain amount of oil given our current infrastructure for GDP, but for the most part we need GDP for oil. In other words, while oil does influence GDP, GDP influences oil wayyyy more...
$this->bbcode_second_pass_quote('wisconsin_cur', 'J')ust because a model (declining global energy available = declining world GDP) is not complex enough to account for a delay between the onset of one and result does not mean that the model is fundamentally flawed; only that it is inadequately complex to account for the delay.
If it can't accurately (not precisely) predict the behavior of a system a model is fundamentally flawed. In other words it needs to be altered until it can assess the behavior of the system accurately, which may or may not be possible at the time. Saying a model that doesn't work isn't fundamentally flawed is akin to saying a tool that doesn't work is still right for the job. I suppose if we try enough to use a hammer to screw a lag bolt into a stud we may eventually get lucky and succeed in some way, but that doesn't mean that we shouldn't use a wrench or similar instead when our initial tool doesn't work very well or at all.

It would have to look the same less the potential for excess storage at any given time. I doubt we even have enough infrastructure to store enough oil to produce a statistically significant difference between consumption and production, not that we would since infrastructure use costs money as well so it's use probably isn't practical...

Are you suggested there would be a significantly different impact on GDP between oil consumption over a decade and it's average?

I'm suggesting that for 5-6 years of that period you characterized as flat consumption, consumption was rising significantly.

The period I was referring to was longer than just five years. If oil production goes down 20% over some time period, and then over some equal time period directly after that increases 20%, is it not accurate to say that over the sum of both periods average production was essentially flat?

$this->bbcode_second_pass_quote('yesplease', 'H')ow can it give a false impression?
Come, on yesplease, I'm sure you're more intelligent than that. You said it was a decade of flat consumption. It most certainly was not flat, essential or not.
$this->bbcode_second_pass_quote('yesplease', 'A')s for the rest, you're doing the same thing wisconsin_cur did. While we do know that economic growth tends to spur increases in the consumption of oil and that oil is required for economic growth currently, we also know from data that economic growth impacts oil consumption far more than oil consumption impacts economic growth.
So, there is a feedback loop. It doesn't really alter the basic point being made.
$this->bbcode_second_pass_quote('yesplease', 'T')his is illustrated by the difference in behavior between the two, where small changes in GDP tend to result in larger changes in oil consumption, while otoh small changes in oil consumption don't seem to result in larger changes in GDP.
Really? Well, global consumption hasn't dropped much, if at all. Developed nations are already seeing a marked decrease in economic activity, however, with many economies seeing quarters of contraction or zero growth, even by official figures. But there does seem to be some inertia.

No, I said...
$this->bbcode_second_pass_quote('yesplease', 'I')f oil production goes down 20% over some time period, and then over some equal time period directly after that increases 20%, is it not accurate to say that over the sum of both periods average production was essentially flat?
So, if we take the average (in mbpd), of year production at 66, 63, 60, 57, 57, 58, 58, 60, 61, 63, 64, 66, 66 over the corresponding 13 year interval we come up with a decade plus average of about 61.5mbpd.
The only way that could give a false impression is if the person interpreting it didn't have even a grade school notion of what an average was.
$this->bbcode_second_pass_quote('TonyPrep', 'S')o, there is a feedback loop. It doesn't really alter the basic point being made.
Of course it does. If we depend for the most part on oil consumption for GDP, then w/o oil we can't have GDP. Otoh, if for the most part we depend on GDP for oil consumption, then even w/o oil consumption we can still have GDP.$this->bbcode_second_pass_quote('Professor Membrane', ' ')Not now son, I'm making ...

$this->bbcode_second_pass_quote('TonyPrep', 'I')f so, it's easy to see why you regard yesplease as making sense. I suppose when oil consumption gets down to the levels of 100 years ago, you'd characterise oil consumption over the previous century and a half (or whatever the period is) as "essentially flat". That would be a fairly useless representation of what actually occurred.
I wish I could say "Come on TonyPrep, I'm sure you're more intelligent than that." But I'm not sure that would be accurate.
If we take some interval/data to measure an average of, and every point between the starting and ending points has a greater value associated with it, then the average consumption will be higher, in this case much higher, than the starting/ending values. Otoh, if we take a period where the starting/ending points have values greater than those in between, then the average (consumption in a recent example) over that period is lower than the values at the starting/ending points.
