$this->bbcode_second_pass_quote('spot5050', 'M')onte, Jevons' Paradox does not apply in world of decreasing supply.
I asked Aaron to weigh in on this as he wrote the Jevon's Paradox thread :
$this->bbcode_second_pass_quote('Aaron', 'S')ure it does.
Jevon's paradox simply says that conservation & efficiency gains make energy less expensive and more available than it would be otherwise.
It applies no matter what the overall condition of the supply.
In fact, the effect of the paradox is more pronounced if supplies are shrinking.
If oil is already cheap, and supplies are growing, then conservation and efficiency gains have a limited impact on prices and availability.
However, if oil prices are high and supplies shrinking, the savings from conservation and efficiency have a bigger impact relative to the potential use of oil.
Energy savings don't get deposited into your energy bank account, waiting for you to use it, but remains on the market making that commodity less expensive that it would have been otherwise, stimulating it's use.
The cheaper our energy becomes, the more we encourage it's use.
Another way to view this is that we use energy at a constant rate... as much as we can afford.
When you make a carburetor twice as efficient, there are no net savings, because you end up with twice as many cars driving twice as far.
