TABLE 1 DEMANDITE AND ENERGY SUMMARY TABLE 2 PER CAPITA ENERGY USE PER YEAR (U.S. — 19681 and enable new materials to serve in new roles (e.g., glass fibers in optical communications can replace copper wires). Demandite does not include the vast quantities of water and air which flow through the biosphere under the combined influence of evaporation from the oceans and worldwide photosynthesis which are driven by solar energy. Nor does it include the soils recurrently used by agriculture. It does not include foods, trees and similar forms driven by solar energy through the cycles of the biosphere. Table 2 breaks down the per capita energy usage. Note that most of the energy (4,5) is used downstream of Demandite production in such activities as manufacturing, transport, construction, and domestic life. We are all aware that considerable energy is required to extract metals from the Earth (note line 5 in Table 1). Metals
