Energy is becoming more and more in demand throughout the world. It is a fundamental necessity for the economic development of a country. It is within this framework that this study is to study the possibilities of optimization of energy consumption and to propose alternative improvements to reduce the energy bill. However, it should be noted that energy management does not mean its total elimination, but rather the identification of savings and the implementation of measures to reduce energy losses while maintaining the same service provided. So in summary, energy efficiency is not consuming less but consuming better.
