This chapter helps understand the present energy consumption across the world and the need for an energy management system similar to the quality and environmental management system in a manufacturing facility. It also helps understand the different national and international management standards and certification programs. To overcome the lack of availability of proper framework to implement an energy management system conforming to the ISO 50001 standard, a standard methodology using flow charts and ISO 50001 Analyzer software is required to be developed which can help perform tasks to realize the best possible results.
