A bit of a digression from the technical issues... there is a notion among techno-optimists like Amory Lovins that with enough efficiency gains economic growth can be "decoupled" from energy consumption. Relative decoupling of energy consumption per unit of GDP is well established but absolute decoupling (where energy consumption has declined and GDP increased) has only occurred seven times in the last 36 years -- and these were "growth recession" years.
A closer look at even relative decoupling, though, reveals the dark underside of what it is that is actually being decoupled. The lion's share of GDP uncoupled from energy consumption has not gone to wage earners. One way to interpret this outcome is to view much of the GDP growth of the last three or four decades as a statistical artifact that hasn't trickled down to middle-income earners -- whether because it was redistributed upward, an increase in that items should have been excluded from the accounts as intermediate goods or both.
