Enjera baking is the most energy-intensive activity in Ethiopia which causes an economic problem, forest degradation and CO emission. This research aims to quantify fuel cost reduction, forest preservation, carbon dioxide emission reduction potential of advanced stoves and influencing factor of their adoption in Werabe University, Ethiopia. To attain its objectives: firstly, Control cooking test on traditional cooking stoves and both single clay and double clay electric stoves was conducted to quantify their fuel use efficiency. Secondly, document analysis was used to investigate forest reservation, fuel cost reduction and carbon dioxide emission reduction. Thirdly, focus group discussion with bakers used to identify the health impact of the traditional cookstove. Fourthly, an interview was also conducted to identify factors determining the adoption of electric cookstoves. The results show, substituting traditional cookstoves by single clay electric stoves or double clay electric stoves can reduce fuel cost by 159% and 148% y. Electric cookstoves can preserve 4.76 and 9.77 ha of dense and open forest cover. The finding also reveals that single clay electric stoves and double clay electric stoves reduce CO emission by 99.08% and 98.87% y. The study also indicates switching traditional cookstove to cleaner stoves avoids IAP; consequently, it improves cooks health. Finally in Werabe University adoption of cleaner stoves is influenced by transmission failure of electricity and lack of attention about the benefit of the clean cookstove. To conclude the study may have economic, environmental and social implication.
英吉拉薄饼烘焙是埃塞俄比亚能源消耗最大的活动,这导致了经济问题、森林退化和碳排放。本研究旨在量化埃塞俄比亚韦拉贝大学先进炉灶在降低燃料成本、森林保护、减少二氧化碳排放方面的潜力以及其采用的影响因素。为实现其目标:首先,对传统炉灶以及单泥质和双泥质电炉进行了对照烹饪测试,以量化它们的燃料使用效率。其次,采用文献分析来调查森林保护、燃料成本降低和二氧化碳排放减少情况。第三,与面包师进行焦点小组讨论,以确定传统炉灶对健康的影响。第四,还进行了访谈,以确定决定采用电炉灶的因素。结果表明,用单泥质电炉或双泥质电炉替代传统炉灶,每年可分别降低燃料成本159%和148%。电炉灶可保护4.76公顷和9.77公顷的茂密和开阔森林覆盖面积。研究还发现,单泥质电炉和双泥质电炉每年分别减少碳排放99.08%和98.87%。该研究还表明,将传统炉灶换成更清洁的炉灶可避免室内空气污染;因此,可改善厨师的健康状况。最后,在韦拉贝大学,采用更清洁炉灶受到电力传输故障以及对清洁炉灶益处缺乏关注的影响。总之,该研究可能具有经济、环境和社会意义。
