FIGURE 9.2 At the top we see again the idealized cycle of energy consumption as obtained in Chapter 8. At the bottom we<br />

see S-curves describing technological growth and substitution processes all normalized to reach <strong>10</strong>0% when they are completed.<br />

The rising part of most curves coincides with the upswing of the cycle indicating growth and prosperity, while<br />

“coordinated” saturation coincides with economic recession.<br />
