As it happens, I was pondering a 'Peak Oil Reason' claim, maybe something like:
When POIL30 or similar subsequent claim is judged what it the main reason for the Peak having been reached
Cheaper other fuels - pays 0
Government taxes/cap/rationing - pays 50
Shortage of remaining oil reserves and/or increased cost of extracting them - pays 100
Defining how that works might be tricky but maybe something can be worked out. If the government action is all taxes and no cap or rationing or similar then it may be possible to compare
(Government taxes close to judgement date-Government taxes in 2019)/selling price of gasoline close to judgement date
(Cost of extracting and refining oil close to judgement date-Cost of extracting and refining oil in 2019)/selling price of gasoline close to judgement date
Even then performing some average of G7 tax rates would be tricky and I am not at all sure about working out an appropriate comparable formula for cheaper other fuels.
Factoring out population or aiming at percentage of world energy.
Interesting ideas, but does it just add complexity to the claim for no particularly good reason? If the claim was likely to span 30+ years I could see merit in the ideas. The claim is set to time out in 2030 if oil production is still rising. If population and total energy use don't change all that much over a 10 year period then it isn't much different. Peak oil production then just seems a cleaner idea than percentage of world energy declining or oil use per capita declining.
So I am not convinced at the moment but if a majority say they would prefer one of these, I will give it further consideration.
