Determining the cost of energy saving measures and the magnitude of their potential application is the first and essential step to correctly design energy efficiency policies, which are in turn a keystone for energy transitions. This is particularly relevant for MENA countries, which feature energy intensities among the highest in the world. This paper presents a methodology for assessing reductions in energy demand based on expert evaluations; the methodology incorporates several improvements over previous similar studies. Our results suggest a significant potential for energy savings, and recommend different policy designs based on the different costs and potentials of different energy saving measures.

确定节能措施的成本及其潜在应用的规模是正确设计能效政策的第一步，也是至关重要的一步，而节能政策又是能源转型的基石。这对于中东和北非国家尤其重要，这些国家的能源强度位居世界前列。本文提出了一种基于专家评估来评估能源需求减少量的方法；该方法与之前的类似研究相比有一些改进。我们的研究结果表明节能潜力巨大，并根据不同节能措施的不同成本和潜力推荐不同的政策设计。
