12. Saving energy at home and finding energy at your feet

Figure 12.1 Indian dwellings in Mesa Verde, Arizona, showed that the Anasazi understood the benefits of energy conservation, as did all early peoples. They had no choice—they lacked the abundant, cheap energy that we are accustomed to. The Anasazi in Mesa Verde built their houses on the south-facing slopes of cliffs, beneath an arch, so that they were shaded from the intense midday sun but warmed by the early-morning and evening sunlight at lower angles.
