Abstract: A sustainable industrial metabolism, integrating technical and ecological aspects should be one of the greatest challenges of humanity within the present industrial world. Starting from the observation that Nature built ordered structures and human beings are only one component in the complex web of the ecological interactions, the focus of this presentation is to enhance the way of thinking that human technical activities cannot be separated from the functioning of the entire system. Based on the strong conviction that Nature has so far generated life, Industrial Ecology seeks for a new approach of the industrial systems, viewed not in isolation from the Nature surroundings systems, but in concert with them. Within the framework of Industrial Ecology, an approach of technical systems, created by humans, and ecological systems, created by Nature, as parts of the same system, the industrial ecosystems, could provide a holistic view of the interactions and symbiosis interrelationships among human activities, industrial practices and ecological processes. This presentation goes on to adopt a dualist view, incorporating technical and environmental dimensions, to describe exergy and embodied energy applicability to electric ecosystems. Drawing up a description of the electric power system as an industrial ecosystem, with its limits and components, defining the systems operation regimes and assessing the equilibrium points of the system within the two reference frames represent key points and issues related to an appropriate analysis of electric power systems. Further on, this presentation aims to shed light the exergy analysis that overcomes the limitations of the energy analysis, and provides an illuminating way of assessing systems meaningfully, since the concept of exergy is based on both the first law of thermodynamics and the second law of thermodynamics. Exergy analysis clearly identifies the locations of energy degradation in a process, revealing how much it is possible to design more efficient an electric power system, being also a tool for addressing the impact on the environment of energy utilization, this way identifying whether an industrial system is sustainable or not.
