Title: Evaluation Knowledge Brief on Review of Energy Efficiency Interventions
Abstract: The Asia-Pacific region’s gross domestic product (GDP) has grown remarkably over the past few decades, and it is anticipated to outpace the rest of the world over the coming years. The region’s rising share of GDP is expected to make it the largest energy-consuming region in the foreseeable future. Unless the Asian Development Bank (ADB) and its developing member countries (DMCs) encourage measures to contain energy consumption, the region will be increasingly exposed to risks related to energy security and climate change. Among the options available to contain energy consumption are the improvement of (i) energy supply-side efficiencies (by reducing energy losses in the supply chain), and (ii) energy demand-side efficiencies (by consuming less energy for same level of service). Energy efficiency (EE) improvement is recognized as a highly cost-effective alternative to increasing energy availability; a megawatt of power capacity saved (e.g., by retrofitting energy-efficient industrial equipment) costs about half that of adding equivalent coal-fired power-generating capacity. Industry and buildings accounted for more than 70% of all energy use and more than 85% of electricity use in the region in 2008, the most recent year for which complete data are available. It is usually difficult to estimate the technical and market potential for EE improvements in industry and buildings. Therefore, scaling up of EE investments in industry and buildings, though highly desirable, is challenging. This evaluation focuses on EE investments in industry and buildings, reviews ADB’s efforts in this area as well as on the supply side, and provides information on how it may further support EE improvement on the demand side. Based on the study, two key lessons are identified to enhance ADB’s participation in demand-side EE initiatives, which could contribute to improved design of demand-side EE interventions. Remaining segments of the executive summary introduce the motivation for the study, the key findings, and some considerations for going forward.
