Abstract

The residential sector in Ethiopia heavily relies on biomass for cooking, using inefficient cookstoves. In order to assess energy policies and decision-making for better economic development, it is essential to have final energy consumption by end-use. However, there is a lack of readily accessible data on residential energy end-use. Our study fills this gap by using data collected from surveys of 590 urban households in Ethiopia, estimating their energy end-use consumption, and analyzing their determinants. The annual final energy consumption per household is about 7.2 MWh, where 90 % is for cooking, baking, tea/coffee boiling end-uses, and only 2.3 % for lighting. The analysis reveals that income has the strongest effect on energy consumption for baking and on miscellaneous end-uses, both directly and partly indirectly as a mediating variable. The study highlights the importance of end-use consumption data to plan energy efficiency, mix technology options, and make suitable policy interventions.

摘要

埃塞俄比亚的住宅部门严重依赖生物质用于烹饪,使用的是低效炉灶。为了评估能源政策和决策以实现更好的经济发展,按最终用途掌握最终能源消费至关重要。然而,缺乏关于住宅能源最终用途的易于获取的数据。我们的研究通过使用从埃塞俄比亚590户城市家庭的调查中收集的数据,估算其能源最终用途消费,并分析其决定因素,填补了这一空白。每户每年的最终能源消费量约为7.2兆瓦时,其中90%用于烹饪、烘焙、煮茶/咖啡等最终用途,而照明仅占2.3%。分析表明,收入对烘焙和其他杂项最终用途的能源消费影响最大,既直接影响,也部分通过作为中介变量间接影响。该研究强调了最终用途消费数据对于规划能源效率、混合技术选择以及进行适当政策干预的重要性。
