Determinants of residential electricity consumption in South, East and South East Asia: A systematic review

Residential electricity consumption (REC) is poised to grow significantly in the emerging markets of the Indian subcontinent and South East Asian region. The study aims to provide a systematic review of studies that have explored the determinant factors of REC in South, East and South East Asia. After screening for eligibility and data quality, 52 studies were selected for systematic review using the PRISMA framework. A systematic review of these studies revealed 113 factors that at least one study reported as having significant impacts on REC. These factors comprised socioeconomic indicators, variables pertaining to building envelopes and occupancies, ownership and usage patterns of appliances, and influence of climate and location. The effect of each of these determinants on REC was recorded, and the relationship was analysed considering the available literature. Using a criterion of being reported as significant by at least five studies, a subset of 21 factors emerged as the key determinants of REC. To our knowledge, this study is the first to present a comprehensive picture of the key determinants of REC in South, East and South East Asia based on a systematic review. The review identifies factors that unambiguously contribute to increasing or decreasing REC and those that require further research.
