This work is intended to contribute to the foundations for formalizing
industrial ecology analyses of energy systems (systems for energy gen
eration, transfer, or transformation) and to examine how the tools for
performing these analyses can also enhance the field of industrial ec
ology in other applications. We discuss requirements for studying mate
rials and energy cycling in industrial processes, with particular emph
asis on energy generating systems, through explicit inclusion of entro
py concepts in industrial ecology considerations. This perspective is
intended to contribute to the theoretical basis for industrial ecology
, to the development of tools for comparing the ecological (human and
environmental health, and institutional) impacts of energy generating
and other industrial processes, and to possible changes in engineering
curricula with emphasis on design. (C) 1998 Elsevier Science B.V. All
