Good morning all.
In my opinion is the global glut from 85-2005 doesn't say much at all about what might happen post peak. I know, on a PO site, doom one upmanship makes it sage to say that not only are we dead but that we've been so for years and are just too stupid to realise. As well, people have been trying to shoehorn any and every event into PO Doom for a decade. Personally I don't think any of that is necessary.
PO is pretty well evident in the 10 years record prices and flatline in conventional production, all that's left is the shouting— i.e.: decline.
My guess is we aren't likely to have a 20 year global glut post decline like we did '85-'05.* Real prices were lower between '85-05 than 1950! Not too Peaky IMHO.
Yeah the US peaked in 1970, but when the world peaks we likely won't be ordering up a tanker-full from Saturn.*

Overall demand fell in the 70-80s because there were huge efficiencies to be gained that we'd never had reason to consider before. But the decline was mostly in industry and power generation uses, transport was not much affected. Transport fuels consumption is pretty rigid short term. But when we pontificate something like "30 years now", it simplistically ignores all other factors— like the historic increase, then decline in workforce participation over the same period.
In the US, miles traveled has been flat the last 7 years post-recession, dwarfing the little blips in growth during the embargoes. Obviously the prices have been higher, longer than in the '70s. But also the workforce change is in exactly the opposite direction, rising then, falling now.
I like this second chart a lot because it illustrates the correlation between miles driven and the falling workforce participation starting in the mid-90s. Participation peaked then fell, and then it fell precipitously post recession... flatlining the average miles right along with the number of commuters. Oil price was a factor but not the only one.

My thought is conventional decline will tell the tale. We won't need to look very hard for peak oil, won't need to shoehorn every dot into the matrix, and I'm pretty sure won't be drawing parallels to the '80s.
