Explore the interconnectedness of efficiency growth and decay in the vicinity of Union Square, NY. Learn how as we create more wealth with a unit of energy, the challenge of reducing energy consumption persists. Discover how consumption growth curves and efficiency decay curves intersect over time, shaping energy inefficiency and wastefulness. Gain insights on the patterns of growth and decay and their implications on energy sustainability.

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…!
