A dilemma is projected to surge on the long run if not properly dealt with. The power sector is totally dependent on fuel, which is a primary source of energy in Egypt, and since the production of energy is not equivalent to the rising demand, so it becomes a major cause behind the power crisis. Efforts so far had been concentrating on the supply side, while neglecting an equally important part of the equation presumed by the demand side. On the other hand, energy efficiency is fast becoming an integral part of the demand, where the residential sector in Egypt plays a very important part with around 47% of power consumption, making it the highest sector consuming energy from the demand side, and hence presents a good opportunity to investigate in term of energy efficiency and the promotion of its applications in order to solve the energy problem, so that later the same concept can be applied in other sectors for a holistic solution to the both the power and the energy problem in Egypt. This study will focus on generating a political framework to promote energy efficiency as a solution to the energy problem in Egypt at end-user’s level.展开更多
