“…These factors have and continue to drive the call for a cleaner energy sector (Adeyanju et al, 2020), particularly as self-generation through privately-owned generators is widespread (Ajenikoko et al, 2018;Adejoro, 2017;Imandojemu and Tonuchi, 2021). Nigeria is the largest user of generators in Africa (IEA, 2019) and the region's 2 nd largest GHG emitter (Ritchie and Roser, 2019) as can be seen in This is despite its noteworthy catalogue of both conventional and RE resources and energy potential (Akhator et al, 2019;Chanchangi et al 2022), described as underexploited and/or overshadowed due to its oil-producing capacity and exportation gains (Abdullahi, et al 2021;Adeyanju et al, 2020;Cervigni et al's, 2013). Nigeria is ranked as a leading country with high solar potential (Ohunakin et al, 2014), with solar recognised not only key to its national energy diversification but also its direct and/or specific use in buildings due to its widespread availability and diverse application (Adesanya and Schelly, 2019;Mas'ud et al, 2021).…”
