How are those relevant?
I could make up data too. Instead everything I post has the name of the author(s) (if given), the name of the source (always) and a link to the original source. Plus I only post reports from 2011 not stale data about the past.
Believe me I could save a lot of time by just posting unsupported random noise instead of something that takes more work to track down and keep on top of.
Admittedly there's the Olduvai Gorge chart but that's just a symbol, I don't consider it to be data.
Pops, your chart doesn't even mention electricity and that is what this thread is discussing so it's off-topic too.
Sorry, the thunder started booming and I had to sign off quick.
I've been updating Duncans charts every year for quite a few years and posting them here. The charts are mine from the BP Stat. Review 2011 & US Census.gov. Duncan originally used BP data in Barrel Oil Equivalent and UN population figures.
Duncan's theory uses primary energy per capita as a measure of civilization, not electricity:
- Electricity is not a primary energy source, but rather an "energy carrier"
-The third, or de-industrial phase lies immediately ahead during which time industrial economies will decline toward a new period of equilibrium, limited by the exhaustion of non-renewable resources and continuing deterioration of the natural environment.
There are a couple hundred pages over at dieoff.org with all Duncan's stuff, Jay Hanson, Jean Laherrere and lots more with good background info, you might want to check it out.
One more thing, if this is your typical attitude, I suggest you dial it back a tad and save us all some effort.
