Sustainability of energy is key for quality life; thus, the use of clean energy at the household level warrants moving from fossil-based energy to modern forms like biogas. However, the joint interactive effect of household income, biogas usage and willingness to adopt a single-stage solar-supported hyper-thermophilic anaerobic biogas digester (SSHTABD) is not known. A cross-sectional survey was carried out to assess the willingness of residents of Elmina to adopt the SSHTABD. Stratified and simple random sampling techniques were used to select 219 respondents fitted into a complementary log–log regression model. Household willingness to adopt the SSHTABD was 86%. Among them are households not willing to use biogas but have high income and households willing to use biogas but have either low or high income are more likely to adopt the technology compared to households not willing to use biogas and have low income. Households not willing to use biogas, but have high income (OR = 1.725, confidence interval [CI] 0.803–3.706) and households willing to use biogas, but have low income (OR = 1.877, CI 1.103–3.188) compared to households willing to use biogas and have high income (OR = 1.725, CI 1.080–3.451) are more likely to adopt the technology as households not willing to use biogas and have low income. Additionally, households employed under the formal government sector, formal and informal private sectors are 40%, 136% and 103%, respectively, more likely to adopt the technology than those unemployed. The high willingness of households to adopt the technology calls for government to support households to own biogas digesters thus requires policy interventions and interdisciplinary research.

加纳家庭愿意采用单级太阳能支持的超高温厌氧沼气池

能源的可持续性是优质生活的关键；因此，在家庭一级使用清洁能源保证从基于化石的能源向沼气等现代形式转变。然而，家庭收入、沼气使用量和采用单级太阳能支持的超高温厌氧沼气池（SSHTABD）的意愿之间的联合交互效应尚不清楚。进行了一项横断面调查，以评估 Elmina 居民采用 SSHTABD 的意愿。分层和简单的随机抽样技术被用来选择 219 名符合互补对数-对数回归模型的受访者。家庭采用 SSHTABD 的意愿为 86%。其中，与不愿意使用沼气但收入较低的家庭相比，不愿意使用沼气但收入较高的家庭和愿意使用沼气但收入较低或较高的家庭更可能采用该技术。与愿意使用沼气的家庭相比，不愿意使用沼气但收入较高的家庭（OR = 1.725，置信区间 [CI] 0.803–3.706）和愿意使用沼气但收入较低的家庭（OR = 1.877，CI 1.103–3.188）使用沼气且收入较高（OR = 1.725，CI 1.080–3.451）的家庭更有可能采用该技术，因为家庭不愿意使用沼气且收入较低。此外，在正规政府部门、正规和非正规私营部门就业的家庭采用该技术的可能性分别比失业家庭高 40%、136% 和 103%。
