This model is then applied to analyze three different scenarios of energy interaction between human society and the ecosystem: (i) societal activity is supported exclusively by biophysical processes for energy input and conversion; (ii) society is fueled by ‘biofuels' (biogas and alcohol) but power is generated by exosomatic technological devices (engines, etc.); (iii) society has ample access to a high-density energy input and exosomatic technological devices. For each scenario limits to human development are discussed, and estimates of a sustainable population size provided on the basis of compatibility between energy throughput in society and the environment.
