In the following thread:
http://peakoil.com/fortopic5726.html
We put forth the following hypothesis:
$this->bbcode_second_pass_quote('', 'M')y hypothesis is that down deep, under all the fluff in the current economy, there is a core of activity that consists of making things, building things, digging things out of the ground, refining, maybe or maybe not shippign things from one place to another, but actual useful work that people are doing, and if you compute oil expenditures for "useful economic work" for this time period, compared to 1981, it's right about the same as it always was, maybe higher now.
to go below the surface of the superficial stats put forth in this article:
http://www.forbes.com/fdc/welcome.shtml
So for the entertainment of the board, I have checked out the BEA tables and made the following calculation: The percentage of the economy that is currently involved in making things, building things, chemical conversion, transportation, and, in general, doing useful economic activity has decreased from 48% in 1987 (the tables only go back that far) to 41% now. I'm surprised it's that high. So, if you extrapolate back to 1981,
that's maybe 50-51%.
Then, adjust GDP for inflation and population (very important and usually ignored) to get an "inflation adjusted population adjusted GDP.
Then, compute the GDP dollars generated by "useful activity" as opposed to fluff, such as suing each other, etc. as described in the other thread.
Then, compare to oil consumption in each of the periods, for a measurement of "oil impact on the economy".
Here is the result:
$this->bbcode_second_pass_code('', ' 1981 1987 2004
Oil Consumption (gb)----------- 5.86 6.08 7.33

Conclusions:
a. As expected the actual energy input needed to do "real work" in the modern economy has remained practically unchaged since 1981 (estimated) and for sure since 1987.
b. What that says, as expected, is that the so-called "energy efficiency" of the current economy is due 100% to the fact that fewer people are making or doing useful work.
c. Does this mean that industry itself is less efficient than they used to be? Well, without further study, it is hard to say, but I imagine it's Jevon's Paradox in action: Any efficiency gained during this period in actual manufacturing, for example, was just offset by the fact that people are driving SUV's to work, and commuting farther.
d. So what are people doing with their time these days, rather than useful work? Here's a little table of the % GDP change, by industry, between 1987 and 2004:
   $this->bbcode_second_pass_code('', ' Arts, entertainment, and recreation 45.3
Administrative and waste management services 41.8
Finance and insurance 38.6
Professional, scientific, and technical services 34.2
Professional and business services 29.4
Health care and social assistance 28.5
Educational services, health care, and social assistance 28.0
Educational services 24.5
Finance, insurance, real estate, rental, and leasing 15.3
Arts, entertainment, recreation, accommodation, and food services 12.2
Real estate and rental and leasing 4.1
Accommodation and food services 3.6
Management of companies and enterprises 1.3
Other services, except government 0.9
Government -8.5
')
As predicted, we are becoming a nation of people entertaining, lending money, managing, and selling insurance to one another. Do not blame the government. Government as a percent of "adjusted" GDP is lower today than in 1981.
d. There is no telling what percentage of the manufacturing and transportation amounts are currently involved in making things that are non-mission-critical, such as DVD's, cellphones, video games, and other gadgets. The transportation sector, per the above, is not really that much bigger than it was in 1987.
e. Kustler's column this morning kind of touches on this issue as well.
f. We will have to wait to see what happens during the next downturn, but I am thinking this will not be pretty.
