Abstract: Traditionally considered, the basic concepts of energy, exergy and embodied energy are founded in the field of physics, having however environmental, technical and economical significance as well, and could be explained, interpreted and applied in a more universal manner, due to their multidisciplinary traits. It means that in Science unclarified, unindexed and unassimilated worlds are unifying and harmonizing, without contradictory frontiers between microscopic and macroscopic phenomena. If we really want to avoid the concept of „on the edge of chaos” then a set of conditions for performance of sustainable technical systems must be formulated. Hence, this study aims to demonstrate, in terms of sustainability, the usefulness of the embodied energy and exergy concepts for analyzing systems which convert energy or matter, particularly, an electric transportation system in a dualist view, technical and environmental.
It is argued in the study the sustainability framework, which revealed tentative steps in „cradle to grave” embodied energy assessment of an electric train, from the manufacturing processes to the train operation regimes modeling. In particular, this study tries to provide a missing link in the analysis of electric transportation systems, a bond between Environment and Science that could be translated into the paradigm: only the win model of the self-organizing systems of Nature as solution for human technology applied will have survival value.
The understanding of the Universe Creation and Revival will be probably out of reach. We will never know actually when and how was exergy created and transformed into life-supporting light in our Sun. But whatever it was, we should take care of our gift-given home, the Earth. All humans who are considering that the Universe is, in a tragic way, transient and imperfect should think to the fragile and running moments of our happiness and try to accept the right of survival for the living Nature. Looking forward, the environmental education should lead to decisive changes in our lifestyle, if we really want the human society to be a true part of the living Nature. Otherwise, if Science will be not directed towards the right purposes of the humanity, sooner or later everything will be passed, and forgotten, and erased.
