Over Time we create more wealth with a unit of energy, - but not enough to reduce energy consumption.
The incentive for efficiency increases, - but you can’t eliminate all waste so the difficulty grows.

It has to level off, so it has to have been steeper too
Energy Inefficiency = Wastefulness
- 1/W
- 1/W
Maximum Efficiency Limit ?
(Is Never Zero Wastefulness!)
Zero
It was less steep before, so the trend is getting steeper
Zero
When reading curves of change over time if you -feel- the intensity of acceleration, as if a rollercoaster ride, it tells you a lot about the complex changes the curve represents.
Decay curves are settling and predictable Growth curves are unsettling and can come to dramatic ends.
Curious Facts Following the present growth trend, every time the world doubles
energy efficiency it doubles energy consumption too…!
