In the 1990s in the latter part of his career H.T. Odum together with David M. Scienceman developed the ideas of emergy, as a specific use of the term Embodied energy. Some consider the concept of “emergy”, sometimes briefly defined as “energy memory”, as one of Odum’s more significant contributions. However the concept is neither free from controversy, and not without its critics. Odum looked at natural systems as having been formed by the use of various forms of energy in the past: “emergy is a measure of energy used in the past and thus is different from a measure of energy now. The unit of emergy (past available energy use) is the emjoule to distinguish it from joules used for available energy remaining now.” This was then conceived as a principle of maximum empower which might explain the evolution of self-organising open systems. However such a principle has not been empirically demonstrated nor verified by the scientific community.

I will be expanding this section eventually. Put simply, I feel this article could be improved a lot.
