Abstract: Traditionally, the basic concepts of energy, exergy and embodied energy are founded in the field of physics. But since these concepts have environmental, technical and economical significance as well, it may be advantageous to explain, interpret and apply them in a more universal manner in line with their multidisciplinary traits. Some argue that science has not clarified and unified technical and ecological viewpoints. To address meaningfully many of the problems facing humanity today, a set of conditions for the performance of sustainable technical systems must be formulated. Here, the benefits are demonstrated of using exergy concepts to understand the efficiencies of electrical technologies and systems and to guide improvement efforts. Although exergy applications in electrical engineering are uncommon, exergy clearly identifies efficiency improvements and reductions in thermodynamic losses for electrical technologies and systems. The research reported here aim!
s to demonstrate, in terms of sustainability, the usefulness of the embodied energy and exergy concepts for analyzing electric devices which convert energy, particularly the electromagnet. A dualist view is adopted, incorporating technical and environmental dimensions. The information provided by energy assessments is shown to be less useful than that provided by exergy and prone to be misleading. It is concluded that exergy has a significant role to play in evaluating and increasing the efficiencies of electrical technologies and systems, and should prove useful to engineers as well as decision and policy makers.
Keywords: Electrical engineering, electromagnet, embodied energy, energy conversion, exergy, magnetic field, magnetic forces, mechanical work.
