Growth & Efficiency in the vicinity of Union Square, NY NY EfficiencyDecay Curve ConsumptionGrowth curve 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.

Growth curve Decay Curve
It has to level off, so it has to have been steeper too Decay Curve - 1/W - 1/W Energy Inefficiency = Wastefulness 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. • On the next slide click to draw a shutter across the view • Look first at one curve then the other, then both Try to feel the experience, easing down off a steep slope and charging up an ever steeper one. Curious Facts Following the present growth trend, every time the world doubles energy efficiency it doubles energy consumption too…!
