I'm a big boy. And they are only words. From someone anonymous at that. My email address is part of my profile. As well as a boring and rarley posted to website. I don't have anything to hide.

And my views will necessarily clash with some members of this forum. It's to be expected on a topic that elicits such, er, passions.

If you can disprove his thesis I would be amazed!!

Figure 3. World Energy Production per Capita: 1920-1999
Notes: (1) World average energy production per capita (ê) grew significantly from 1920 to its all-time peak in 1979. (2) Then from its peak in 1979 to 1999, ê declined at an average rate of 0.33%year. This downward trend is the "Olduvai slope", discussed later. (3) The tiny cartoons emphasize that the delivery of electricity to end-users is the sin quo non of the 'modern way of life'. Not hydrocarbons.
Observe the variability of ê in Figure 3. In detail: From 1920 to 1945 ê grew moderately at an average of 0.69%/year. Then from 1945 to 1973 it grew at the torrid pace of 3.45%/year. Next, from 1973 to the all-time peak in 1979, growth slowed to 0.64%/year. But then suddenly - and for the first time in history - ê began a long-term decline extending from 1979 to 1999. This 20-year period is named the "Olduvai slope," the first of the three downside intervals in the "Olduvai schema."
Bottom Line: Although world energy production (E) from 1979 to 1999 increased at an average rate of 1.34%/year, world population (Pop) grew even faster. Thus world energy production per capita (ê) declined at an average rate of 0.33%/year during these same 20 years (Figure 3). See White's Law, top of this section.
Acknowledgments: As far as I know, credit goes to Robert Romer (1985) for being first to publish the peak-period data for world energy production per capita (ê) from 1900 to 1983. He put the peak (correctly!) in 1979, followed by a sharp decline through 1983, the last year of his data. Credit is also due to John Gibbons, et al. (1989) for publishing a graph of ê from 1950 to 1985. Gibbons, et al. put the peak in 1973. But curiously, neither of the above studies made any mention whatever about the importance of the peak and decline of world energy production per capita.
The 1979 peak and decline of world energy production per capita (ê) is shown on page 40 of BP Amoco (2000), www.bpamoco.com/worldenergy. Have a look.

Although all primary sources of energy are important, the Olduvai theory postulates that electricity is the quintessence of Industrial Civilization. World energy production per capita increased strongly from 1945 to its all-time peak in 1979. Then from 1979 to 1999 - for the first time in history - it decreased from 1979 to 1999 at a rate of 0.33%/year (the Olduvai 'slope', Figure 4). Next from 2000 to 2011, according to the Olduvai schema, world energy production per capita will decrease by about 0.70%/year (the 'slide'). Then around year 2012 there will be a rash of permanent electrical blackouts - worldwide. These blackouts, along with other factors, will cause energy production per capita by 2030 to fall to 3.32 b/year, the same value it had in 1930. The rate of decline from 2012 to 2030 is 5.44%/year (the Olduvai 'cliff'). Thus, by definition, the duration of Industrial Civilization is less than or equal to 100 years.
