“…Total annual income and access to credit were significant variables (p < 0.01) and distance to firewood sources, distance to water sources and access to electricity did also significantly (p < 0.05) influence the decision to adopt biogas technology. The influence of these variables on the household's decision to adopt biogas technology is consistent with previous findings [3,36,39] in Ethiopia [17], Bangladesh, and Uganda [16]. Most of these factors affected households' decisions to adopt biogas technology in Africa [1,14,30].…”

“…Households' access to electricity decreased the probability of adopting biogas technology by a factor of 0.047 compared to households lacking access to electricity. As opposed to this finding, in a previous study by Kelebe et al [39] in northern Ethiopia a positive relationship between access to electricity and the adoption of biogas technology was ascertained. However, rural households with, perhaps, access to electricity prefer electricity to the biogas technology for its lower cost for connection, maintenance and purchasing of spare parts.…”

“…Access to water is mandatory for biogas production and, hence, biogas technology adoption [4]. To avoid a shortage of water, most adopters connected their toilets to the biogas digesters, which is also supported by an earlier finding in northern Ethiopia [39].…”

“…Household heads with a higher education level had better ability to adopt a technology than their counterparts [40,41]. Years of education of the household head had likewise a significant positive association with biogas technology adoption in Ethiopia [39], Kenya [15], and Bangladesh [17]. This might be due to the fact that households with no or low formal education are more likely to be skeptical to take up a new technology than are their counterparts.…”

Background: Renewable energies such as biogas are considered as clean sources of energy that minimize environmental impacts and are sustainable with regard to current and future economic and social needs. Biogas offers an attractive option for replacing the unsustainable usage of traditional energy sources such as firewood, cow dung, and charcoal in developing countries. In Ethiopia, these energy sources have been in decline. To address these challenges, mainly in rural areas, biogas technology has been domesticated since 2009, as seen in the National Program. The purpose of this study is thus to examine factors that influence households' decisions of adopting biogas technology in rural areas in southern Ethiopia. Methods: A sample of 268 households with 134 biogas adopters and 134 non-adopters were surveyed using simple random and purposive sampling techniques, respectively. The data were collected through individual interviews of households using a semistructured questionnaire. Descriptive statistics and a binary logistic regression model were used for the data analysis. The binary logistic regression model was applied to identify determinant factors affecting the adoption of biogas technology. Results: The results of the study indicated that biogas adopter and non-adopter households had significant mean differences in education level, cattle size, household income, farmland size, number of planted trees as well as the distance to water sources, market places, and firewood sources. Level of education, level of income, access to credit, distance to firewood sources, and access to electronic media had a significantly positive influence on the adoption of biogas technology. Conversely, distance to water sources and access to electricity had a significantly negative influence on the adoption of biogas technology. Conclusions: Biogas technology mostly appears in privileged households having a better socioeconomic status and other resource endowments. The beneficiaries are thus households that can afford the higher initial investment costs for bio-digester installation, maintenance services and purchasing bio-digester spare parts; as well as households that have access to credit facilities, water sources for adequate water supply, markets for purchasing spare parts and electronic media for information, and also households residing far away from firewood sources.

“…This situation could be improved by using biogas (Kamp and Forn, 2016). The deployment of biogas energy as alternative energy source can have the potential to fill the gap in the energy needs of the rural community if it is effectively managed and appropriately utilized (Kelebe et al, 2017).…”

Biogas technology, which converts biological waste into energy, is considered as an excellent tool to improve the lives, livelihoods, health, ecosystem and economy. In Ethiopia, biogas technology has been domesticated to improve the rural energy security and household’s income by reducing their dependence on traditional biomass energy and chemical fertilizers. The profitability of biogas installation is rendered doubtful despite its numerous benefits and domestication efforts. Hence, this study aimed at evaluating the cost-benefit analysis and Profitability of biogas technology at household level in West Hararghe zone, Eastern Ethiopia. A multi-stage sampling technique was employed to select sample households. A total of 105 biogas adopter households were selected for household survey. Results indicated the most commonly domesticated plant is fixed dome biogas with volumes of 6 m 3 and 8 m 3 . Investing 6 m 3 biogas plant with subsidy (0.73 year) had short payback period (PBP) than the 8 m 3 plant (0.97 year). This implies, subsidy has been attracting households into biogas adoption. The benefit cost ratio (BCR) under assumption with subsidy was found to be 1.34 and 1.10 at 10% discount rate for 6 m 3 and 8 m 3 plants, respectively. Under both assumptions with and without subsidy, the NPV results for 6 m 3 and 8 m 3 biogas plant sizes turn out positive. In general, the results of PBP, BCR and NPV shown that the biogas investment is preferable and profitable for continuing the investment for the future.
