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 cant
eliminate all waste so the difficulty grows.

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!
