"Embodied energy" was abandoned altogether in 1986 when David Scienceman, a visiting scholar at the University of Florida from Australia, suggested the term “emergy” and "emjoule" or "emcalorie" as the unit of measure to distinguish emergy units from units of available energy.
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.
