$this->bbcode_second_pass_quote('pstarr', '[') So yes there is elasticity at the margins, but over time since we industrialized petroleum use always increases at 2% per year regardless of recessions etc. (except for that one time period in the late 70' and early 80's, when the Moore's Law of Conservation kicked in once and only once.)
PStarr, where do you GET this stuff?
Using this as a reference
http://www.eia.doe.gov/aer/txt/ptb1105.htmlI would instead state the following.
Oil production grew at approximately 7.3% per annum from 1960 until until peak oil in 1974. This greater rate of increase is visible in this graph as well, using the slope during the upswing as an approximation for the exponential increase of 7.3%.
Image size edit per Code of Conduct, please limit the size of the pics. It's stretching the size of the page here. You can shrink and re-list the chart later on. Thanks for the compliance. Blu Notice how, after the period you have referenced, the recessions of the 70's, early 80's, the slope of the increase is different. Referencing the EIA table again and recalculating, it becomes obvious that the average increase from about 1985 to another peak oil in 2005, the increase was now 1.6% on average.
Now, I realized you referenced rate of growth since the beginning of "industrialization", the date of which you don't mention.
It strikes me that this way of measuring the rate of growth, except for the time period you don't like, is fraught with peril. For example,since the peak oil referenced in this information in 2005, oil production has shrunk again through 2007. Conventional of course.
But that slope change which took place in the 70's, early 80's, is pretty darn indicative of a seismic shift from one regime of growth to another, which means categorizing the entire mess as "2% since the beginning of wherever" is just WAY too big of a generalization,
Goodness gracious, the information has peak oil in 1974, 1979, 1998, 2000, and 2005!
I don't mind all the wild claims of growth, but I think you should at least recognize that in the 47 years referenced, 13 out of 47 years ( 27% of the time ) we were using LESS year over year, thereby completely resetting any calculations on where the next growth number begins from!
That certainly precludes a constant 2% growth rate forever when the thing can SHRINK in the middle!
