The international scientific community has considered the efficient use of energy in production systems to be extremely important for sustainable development. This paper studies the improvement of energy efficiency in industrial motor systems through technological change. Initially, a literature review was conducted to present the main actions necessary for and barriers to overcome to improve energy efficiency in industrial energy systems and to highlight the application of a multi-criteria approach in the case of technological change. The paper presents a case study recommending the prioritization of replacing electric motors using the multi-criteria method called PROMETHEE II. The study reveals that the choice of criteria can significantly change the priority of the technologies to be replaced, thus significantly impacting the performance of new technologies. The paper emphasizes the importance of participation from all areas of the company to attend to the organization’s interests.
