Abstract: By 2035, global energy demand will grow by more than a third. Half of this growth will come from China and India, but a significant growth from populous and developing countries is also expected. Energy efficiency has become one of the main pillars of the mankind development. It is an invisible and underappreciated source, supporting economic growth, improving social development, promoting environmental sustainability, and ensuring energy security. Industries consume a substantial amount of electrical power, and most electricity is demanded by motor systems. However, the complexity of the energy industrial system requires proper energy management associated with competent decision tools. This chapter sets out a framework to promote energy-efficiency programs by assisting industries to replace inefficient technologies, e.g., old industrial electric motors. The framework supports the design and evaluation of motors replacement opportunities and suggests a practical plan of replacement considering investments and energy-saving conditions.
