Are we re-entering the dark ages? Tue 19 Apr 2005 by JOHN BOWKER
SENIOR CITY CORRESPONDENT:
ENERGY is one talking point Labour is hoping will not rear its head during the next couple of weeks. A full-blown power failure would be a disaster for the government’s credibility - and with it the chances of an historic third term.
Like the MG Rover debacle, blackouts similar to those in the United States, Italy and the UK two years ago would be yet another example of complacency by this government. It might be why we are heading for the ballots in May; having negotiated the winter months, a spring election should make it easy to keep the lights on.
However, a report just out from PricewaterhouseCoopers (PwC) says we are about to be plunged into darkness again - and not just in the UK. Worldwide, populations are suffering from poor levels of energy investment and ageing power plants. The research calculates that about $12.7 trillion (£6.7tn) of investment, greater than the entire US annual economic output, is understood to be needed globally to meet an expected doubling in electricity consumption through 2030. That total raises the bar above the estimated $10tn electricity spend agreed by the International Energy Agency (IEA) for the same period.
"Blackouts are expected to become more frequent," the report damningly concludes. "Two-thirds of utility respondents believe the likelihood of blackouts will increase or remain the same, while only a quarter think it will reduce." The findings are based on a survey of 119 investors and utilities executives in 36 countries.
By 1996, however, I had successfully tested the Olduvai theory against numerous sets of data. Four of these tests are graphed in Figure 2. The following facts emerge.
1. On the average, world per capita energy-use reached a maximum value (i.e., a peak) in 1977.
2. The 1977-1995 rate of decline has averaged 0.90% per year.
3. Per capita energy-use will continue to decline as long as the world population growth rate exceeds the energy growth rate.
4. If the decline continues (and extinction is avoided), human societies will bottom out at the subsistence level of energy-use.
The Olduvai theory explains the Figure 2 data, but the exponential-growth theory (of mainstream economics) and the steady-state theory both fail.
The Olduvai theory cannot be overthrown (i.e., scientifically rejected) by outrage or indignation. However, it can be overthrown by either, (1) demonstrating that the four sets of data in Figure 2 are in error, or (2) by gathering additional data over the next few decades and demonstrating that the Olduvai theory cannot explain that data. In any case, the data will be the final arbiter.

Statistics are there to prove that Energy efficiency measured in terms of Energy consumption per dollar of GDP has improved steadily over the years. See for example this chart : http://www.eia.doe.gov/emeu/25opec/sld022.htm
What does that means ? It means that even if "in volume" Energy consumption decreases, that decrease can be balanced by better energy utilization which at the end is what matters the most.
Don't get me wrong. I'm not an advocate of "Business as usual". Energy efficiency won't go up indefinitely and there are big disparities between countries (Developped vs Developping) but that parameter is important for one to comprehend the big picture.
The ancient Chinese philosophical symbol yin-yang represents the understanding of the workings of the universe. This image may be illustrative as we think about the cycling of global crude oil inventories from region to region.
So far this year, oil demand growth has remained strong globally, with China and the United States vying for petroleum supplies. China’s demand growth has accelerated over the past two years, stretching OPEC production to near capacity levels, given that non-OPEC sources are pumping at capacity, if not nearing their peak.
With low spare capacity, the global supply chain is struggling to meet all needs evenly, resulting in a cycling of tightness from region to region, as price differentials attract imports into one area and out of another. As prices fall in the well-supplied area and rise in the less well-supplied area, the pattern is reversed and imports flow in another direction.

2. When you engage in actual fighting, if victory
is long in coming, then men's weapons will grow dull and
their ardor will be damped. If you lay siege to a town,
you will exhaust your strength.
3. Again, if the campaign is protracted, the resources
of the State will not be equal to the strain.
4. Now, when your weapons are dulled, your ardor damped,
your strength exhausted and your treasure spent,
other chieftains will spring up to take advantage
of your extremity. Then no man, however wise,
will be able to avert the consequences that must ensue.
5. Thus, though we have heard of stupid haste in war,
cleverness has never been seen associated with long delays.
6. There is no instance of a country having benefited
from prolonged warfare.
