Document Summary

For most organisms in nature, population growth rate slows to zero as population approaches a limit. A period in which fundamental changes occurred in agriculture, textile and metal manufacturing, transportation, economic policies and social structure. High energy density - many joules per gram. Used for more than just fuel: all synthetics and plastics. Easily adaptable for large and small power plants. The energy cost of acquiring an energy resource; one of the objectives is to get out far more than you put in. Eroi = sum of the energy returned to society/energy required to produce, deliver, and use the energy. 8 methane + 16 oxygen = 8 carbon dioxide + 16 water. Carbon and hydrogen + 12. 5 oxygen = 8 carbon dioxide + 9 water. 8 carbon + 8 oxygen = 8 carbon dioxide. In terms of energy content, natural gas produces the least carbon dioxide, and coal the most.
