in the party's over book, it's thought that the peak would apprx. 4 years of a plateau, bumping up and down.

From a economical-theoretical point of view the peak is magical because of the following:

'Peak' means no more growth is possible. Up to peak, economics was based on growth. From the peak afterwards, economics must be based on diminuishing resources.

Therefore, peak implies a change in economic paradigm, which IS a big thing.

Not quite correct, unless you assume that "peak oil" is equivalent to "peak energy", which is unclear.

It is fair to say that it means "peak transport", at the very least a temporary peak. And that does have all sorts of economic repercussions. I'm still trying to figure it out.

It's certain that the current economy can't deal with peak oil. It's already showing cracks all over. Considering the past records, it's likely that it will fail with a big crash. My preliminary study suggests that the economy should crash before the peak, but there are signs that we already could be in the plateau and the economy hasn't fallen apart yet... I suspect we won't understand exactly what happened to the economy until after it's crashed. I suspect we are on the top of the biggest financial bubble ever. Everyone is borrowing like there's no tomorrow.

Well seeing that oil is our No1 primary energy source, powering 97% of transport and modern agricultural processes, and is soon to go into terminal decline, with no apparent substitute in sight, I would suggest that peak oil does indeed signify peak energy. Especially since No2 on the hit parade, gas, is also only 10 years or so behind and these two sources alone account for 60% of the total global energy supply.

From that, it seems clear we must "magically" replace 60% of the total global energy supply (plus additional demand) within the next ten years or so. What are the odds?

Well not exactly as we don't have to replace all 60% within 10 years - just a substantial proportion, due to decline, which as you pointed out is highly unlikely.

*pokes sleeping brain* :oops:

Right, so, something like 5 - 15% of 60%, per year, plus additional demand. Still looks like a lot to replace...

Yes, 5 to 15% plus the additional demand due to exponential population and economic growth would mean we would need to "replace" (if indeed replace* is the operative word) 3 - 9% of oil and NG capacity, year in year out!

At a rough guess that's around 250,000 to 750,000 megawatts of power, or 250 to 750 1000 MW nuclear reactors, or 100,000 to 300,000 2.5 MW wind turbines, or 25,000 to 75,000 10 MW solar panel farms, or never mind I think you get the picture....

*Based on world energy demand of 14.2 terrawatts
