It's almost as if you people think that peak oil is some kind of voluntary politically progressive phenomenon. Oil production will be 50% less globally in 17 years at a 4% annual decline rate.

The best thing that could happen right now, for the U.S at least, would be for most of the world to experience a re-birth in old-school maoism. China used so much less energy when they were true communists. Mugabe and Chavez are a good start.

Where do you get the 4% decline figure? Out of the money tree?

* Global annual decline rate: 4% - 6% / year?

So 4% is actually on the optimistic side.
Calculation is ln(.50)/ln(.96) =~ 17 for 6% ln(.50)/ln(.94) = 11.2 years. This is assuming we are past peak of course.

My, you are good, aren't you. Did somebody teach you about logarithms recently? Since quantities aren't logarithmic, the calculation you provided is nonsense.

Since quantities aren't logarithmic, the calculation you provided is nonsense.

Your objection makes no sense, a fact which is easy to see if you just plug his numbers back in:

4% decline for 17 years = (0.96)^17 = 0.499587 = 50% less

Tag him for basing the calculation on a wild-ass guess, sure, but the calculation itself is correct.

Hi abelard,

I appreciate your point: "Oil production will be 50% less globally in 17 years at a 4% annual decline rate."

The rates are quite dramatic, no matter what they are, really (it seems to me). That said, I'd characterize the attempt here ("thought-experiment") as more like an effort to see what ideas and plans might be put forth, using "voluntary", and perhaps even "politically progressive" as part of the cultural components of dealing with the hard geologic facts.

In terms of China:

"The plan is generally agreed to have failed in its intentions, leading to millions of deaths plus widespread economic dislocation, and is widely regarded both in and out of China as an unmitigated policy disaster."
