This document discusses energy efficiency and its importance. It defines energy efficiency as the level of energy consumption required to provide a given service based on both technical and non-technical factors. The benefits of energy efficiency include energy savings, increased disposable income, reduced greenhouse gas emissions, poverty alleviation, and job creation. However, energy efficiency also faces costs in the form of rebound effects, where consumers increase their consumption in response to energy efficiency gains. The document also examines energy efficiency in Jordan, where initiatives aim to increase renewable energy production and public awareness to reduce energy demand.
