Energy Conservation and Efficiency

Energy conservation and energy efficiency may relate to each other, but they have different meanings in the energy world. Energy conservation is associated with behaviors and habits to use less energy while energy efficiency involves using technology without compromising the quality and service to perform the same function. In this chapter, some terms used in energy management were given first. Next, various approaches to energy management were compared while energy management system standard was briefly explained. The energy planning process covering energy baselines, objectives, targets, indicators and action plans was then described. After that, a total of 25 energy-saving opportunities was presented. Finally, some energy-saving checklists were given in tabulated forms. It may be concluded that a systematic approach is needed to achieve energy efficiency. In this regard, establishing an energy management system standard at enterprises may help continually improve energy performance, which includes energy use, energy consumption, energy efficiencyand energy intensity.
