The adoption of solar energy by households is an important avenue of protecting the environment and enabling energy access in rural areas, especially in developing countries like Uganda, where energy access is low. Therefore, this study aims to investigate the factors that influence the households’ willingness to adopt solar photovoltaic (PV) energy and how soon the households are willing to adopt solar PV energy for business use in Uganda.

Heckman’s two-step selection model was used to determine the willingness and urgency of adopting solar PV energy for business use in selected districts in Eastern Uganda. The respondents were selected purposively at the household level at a given point in time.

Results show that sex, household head estimated income, mode of acquisition and repayment terms of solar technology positively influence both willingness and urgency to adopt solar energy for business use in households. However, financial disclosure only influences willingness to adopt solar. Then, age and energy need only significantly influence how soon the household is willing to adopt solar PV energy for business use.

This study’s findings essentially apply to the individual factors that determine the willingness and urgency to adopt solar PV energy for business use by households. Hence, further research is needed to understand the external and industrial factors which could strengthen the predictive potential of the elements in this study.

This study underscores the need for regulatory enforcement on the supply and usage of quality, reliable and affordable solar equipment which are suitable for business use. Also, the need to promote and finance the usage of solar PV as a green energy source for household businesses has been emphasized.

The study simultaneously examines the willingness and urgency to adopt solar PV energy for household business purposes using Heckman’s two-step selection model. This has hitherto remained unknown empirically.

As higher education institutions (HEIs) have increasingly turned to consider sustainability over the last decade, education for sustainable development (ESD) has emerged as a way of imbuing students with the skills, values, knowledge, and attributes to live, work, and create change in societies facing complex and cross-cutting sustainability challenges. However, the question of how HEIs can actively embed ESD more broadly in and across curricula is one that continues to challenge institutions and the HE sector as a whole. While traditional teaching practices and methods associated with subject-based learning may be suitable for educating students about sustainable development, a re-orientation towards more transformational, experiential and action-oriented methods is required to educate for sustainable development. The need for educators to share their practices and learn lessons from each other is essential in this transformation.

This paper presents a selection of practical examples of how to embed a range of interactive, exploratory, action-oriented, problem-based, experiential and transformative ESD offerings into HE teaching practice and curricula. Presented by a group of academics and professional services staff at the University of Strathclyde who lead key modules and programmes in the institution’s ESD provision, this paper reflects on five approaches taken across the four faculties at Strathclyde (Humanities and Social Sciences, Science, Engineering and the Strathclyde Business School) and examines the challenges, practicalities and opportunities involved in establishing a collaborative programme of ESD.

This case study was developed using data from secondary sources. The data was collected from the organization’s website, annual reports, press releases, published reports and documents available on the internet.

According to the International Energy Agency’s (IEA) World Energy Outlook (WEO), 775 million people worldwide would not have access to electricity even by 2022, with the majority of them living in sub-Saharan Africa (SSA) (Cozzi et al., 2022). In SSA, energy poverty had been a serious issue over the years. According to the IEA, 600 million people lacked access to electricity in 2019, while 900 million people cooked with traditional fuels (Cozzi et al., 2022). A World Bank report from 2018 said many SSA countries had energy access levels of less than 25% (Cozzi et al., 2022). Energy poverty in SSA hampered sustainable development and economic growth.

Despite significant efforts to address this poverty, Africa remained the continent with the lowest energy density in the world. Although solar and other energy-saving products were appealing, their adoption rates were modest, and their distribution strategies were not particularly effective. The lack of electricity exacerbated a number of socioeconomic problems, as it increased the demand for and use of wood fuel, which caused serious health problems and environmental harm.

While working in Uganda, Katherine Lucey (Lucey) saw that having no electricity had negatively affected women’s health in particular because it was women who were responsible for taking care of the home. These effects were both direct and indirect. The women’s reliance on potentially harmful fuels for cooking, such as firewood and charcoal, resulted in their suffering from respiratory and eye problems, in addition to other health issues. Furthermore, the distribution of energy-saving and renewable energy items was seen as the domain of men, and there was an inherent gender bias in energy decisions. Women were not encouraged to participate in energy decisions, despite the fact that they were the ones managing the home and would gain from doing so. In addition, because there was no light after dusk, people worked less efficiently. Lucey saw the economic and social difficulties that electricity poverty caused for women in rural Africa. She also witnessed how the lives of a few families and organizations changed after they started using solar products. This motivated her to start Solar Sister with the mission of achieving a sustainable, scalable impact model for expanding access to clean energy and creating economic opportunities for women.

Solar Sister collaborated with local women and women-centric organizations to leverage the existing network. Women were trained, provided all the necessary support and encouraged to become Solar Sister Entrepreneurs and sell solar products in their communities and earn a commission on each sale. To provide clean energy at their customers’ doorstep, the Solar Sister Entrepreneurs received a “business in a bag” – a start-up kit containing inventory, training and marketing assistance.

Solar Sister’s business model empowered the women in SSA by providing them with an entrepreneurship opportunity and financial independence. Also, the use of solar products helped them shift from using hazardous conventional cooking fuels and lead a healthy life. The children in their households were able to study after sunset, and people in the community became more productive with access to clean energy.

The COVID-19 pandemic outbreak, however, had a serious impact on Solar Sister. It found it challenging to mentor and encourage new business owners due to restrictions on travel and on group gatherings. The Solar Sisters were unable to do business outside the house either. Their source of income, which they relied on to support their families, was therefore impacted. The COVID-19 outbreak also slowed down the progress achieved by the community over the years and made household energy purchasing power worse. Furthermore, the organization was also grappling with other issues like limited access to capital, lack of awareness and infrastructural challenges. Another challenge lay in monitoring and evaluating the organization’s impact on the last mile.

In the absence of standardized measurement tools and issues in determining the social impact of Solar Sister, it would be interesting to see what approach Lucey will take to measure the impact of Solar Sister on the society. What measurement tool/s will Lucey implement to gauge the social impact of Solar Sister?

This case is intended for use in PG/Executive-level programs as part of a course on Social Entrepreneurship and Sustainability.

Emergency humanitarian medical cold chains (HMCCs) depend heavily on their supporting energy services due to end-to-end temperature requirements in volatile disaster situations. Most energy sources powering emergency HMCCs are fossil-based due to well established processes, regardless of their environmental impact. In response to the recent energy crisis and climate change, a solution to tackle this issue relies on renewable energy sources (RES), whose use has increased to promote climate resilient development. Nevertheless, RESs’ capacity to replace conventional energy services in emergency HMCCs remains poorly understood. This study aims to investigate opportunities for, and barriers to, increasing the use of RESs in emergency HMCCs, thereby enhancing their environmental sustainability.

Based on a review of academic and practice literature, interviews with expert practitioners on emergency HMCCs and sustainable energy, and case study examples, this research aimed to analytically generalise the phenomenon by investigating opportunities for, and barriers to, increasing the use of RESs in emergency HMCCs. The phenomenon is illustrated in a novel framework of typical HMCC, that forms a contextual basis for future research.

A conceptual framework of typical emergency HMCC shows energy-consuming sections where RES can best be increased. This research is put forth in four propositions to manage the opportunities and barriers of the transition.

This research is, to the best of the author’s knowledge, the first attempt to operationalise sustainability by linking energy with HMCCs’ logistical activities in complex emergency settings. The cross-findings from literature, example cases and interviews together demonstrate the need to increase the use of RES in HMCCs, and how to do it.

Tanzania is rich in small hydropower (SHP) potentials. However, many of these potentials have yet to be fully used, and more than two-thirds of its rural population lacks access to electricity. The purpose of this paper is to explore the role of SHP stations in improving rural welfare in the southern highlands of Tanzania. It further explores the history, cost-effective analysis and threats to the sustainability of SHP as one of the renewable energy sources.

The study uses a qualitative research design to explore respondents’ views on the role of SHP stations in facilitating rural electrification and welfare improvement. Primary data were gathered using semi-structured interviews with the 27 key informants and beneficiaries of SHP stations from the Southern Highlands of Tanzania. In addition, the study used documentary research to complement the information from the field survey.

The findings found that SHP stations enhance rural electrification and welfare by providing electricity in remote areas with sparse populations. They operate as standalone off-grids, often by church communities and individuals. However, the sustainability of SHP stations is hampered by challenges such as climate change impacts, high capital investment costs, heavy siltation of small reservoirs, skilled manpower shortages, limited local manufacturing capabilities and infrastructural issues.

The study contributes to the ongoing debate on renewable energy supply and uses, focusing on how SHP stations could contribute to sustainable rural electrification and achieve the 2030 United Nations agenda for sustainable development, which, among other things, aims to safeguard access to sustainable and modern energy and alleviate energy poverty.

The surging cost of living and shortage of affordable and sustainable homes fuel the global housing crisis. Earthship buildings are marketed as the epitome of affordable and sustainable alternative housing. This paper aimed to elicit the perception of Earthship buildings among youngsters in the United Kingdom using immersive virtual reality technology. Additionally, the impact of virtual reality on perception compared with two-dimensional drawings was investigated in the study.

A three-phase, experiment-based survey was adopted: Phase 1: literature review, Earthship house model conception and the virtual environment creation; Phase 2: two-dimensional drawing-based pre-visualisation survey; Phase 3: virtual reality–based post-visualisation survey.

The findings indicated that youngsters had a remarkable, positive change in attitude towards the uptake of the Earthship houses after virtual reality visualisation. In contrast, sustainability experts shared more concerns regarding the concept's viability in the United Kingdom, even after the virtual reality visualisation. However, both youngsters and experts agreed with the pre-eminence of virtual reality over two-dimensional drawings.

The lack of awareness about Earthship buildings for posterity was noted in previous studies, which could be attributed to there being very few Earthship buildings in the United Kingdom. The importance of this awareness among youngsters cannot be over-emphasised since youngsters are affected most by the shortage of affordable and sustainable homes. This gap was addressed by enlightening the youth about Earthship houses and imparting awareness through near-real-life virtual reality visualisation.

Nanotechnology's rapid development worldwide is a significant measure for countries to strengthen the building of energy security. Thus, to empirically investigate the underlying effect of nanotechnology on energy poverty alleviation, the authors of this study assess the impact of nanotechnology on alleviating energy poverty in developing countries.

The paper used panel data for 56 developing countries over the period 2012–2019, by employing dynamic generalised method of moments (GMM) analysis.

The findings showed that the emergence of nanotechnology has a significant trend in increasing energy poverty in developing countries. This suggests that whilst nanotechnology may be a promising solution for addressing energy poverty in certain contexts, nanotechnology may not be the most viable option for reducing poverty in developing countries. The findings have added credence as the findings are robust to the inclusion of alternative energy poverty measures and additional controlled variables.

Although this study results show unpromising outcomes in addressing energy poverty in developing countries, the authors believe that this may be a short-term phenomenon. In the long run, policies and programs must be put in place to support the development and deployment of nanotechnology to reduce energy poverty.

The authors believe this is the first attempt to examine the dynamic influence of nanotechnology development on energy poverty in developing countries. From the standpoint of nanotechnology development, this can help policymakers develop rules and regulations to tackle energy poverty.

This study aims to examine the impact of socioeconomic factors on electricity usage and assess the feasibility of implementing a mini-grid system in Kasangazi, Malawi. The primary aim is to understand the community’s current and potential utilisation of electrical equipment.

A mixed-methods approach was used to collect quantitative and qualitative data. Information was gathered through structured questionnaires, and energy audits were conducted among 87 randomly selected households from 28 Kasangazi communities. Data analysis relied on descriptive statistics using IBM SPSS version 28.

The study indicates that every household in Kasangazi uses non-renewable energy sources: 60 households use disposable batteries for lighting, 20 for radios and all use firewood, freely sourced from local forests, for cooking and heating water. The study shows that firewood is the community’s preferred energy source, illustrating the challenges faced in the fight against deforestation. Most household income comes from farming, with smaller contributions from businesses, employment and family remittances. Access to higher education is scarce, with only one out of 349 family members receiving tertiary education. Despite the constraints of low education levels and income, there is a demand for larger electrical appliances such as stoves and refrigerators. This underscores the need for mini-grid solutions, even in less technologically advanced, agriculture-dependent communities.

This study underscores that in Sub-Saharan Africa, factors like household size, income and education levels do not significantly influence the electricity demand but should be taken as part of the fundamental human rights. Rural populations express a desire for electricity due to the convenience it offers, particularly for appliances like refrigerators and stoves. Mini-grids emerge as a viable alternative in regions where grid electricity provision is challenging. It is concluded from this paper that the issue of using renewable energy should not only be taken for environmental preservation but also to promote energy access, augmenting efforts in supplying electricity to the remotest parts of the country.

Despite the existing gaps in the use of technology in East Africa, the region is among the fastest-growing mobile data users on the continent. This progress is partially attributed to local initiatives to develop and adapt homegrown technologies to local contexts to increase their accessibility and use even in the remotest areas. In this chapter we identify a few of these innovations in Kenya, Rwanda and Uganda and examine how they have been indigenised to fit local contexts as well as the processes of their diffusion, adoption, affordability and accessibility among users and their everyday gratifications from the innovations. The socio-technological assemblage theory, which illuminates the influences of, and the connections between various types of actors and their roles, visions, ideas, concepts and the technological products, informs our inquiry. Other related concepts including ‘innovation’, ‘indigenisation’ and ‘diffusion’ are discussed to understand the homegrown technology innovations and their adaptability. Discussions with both innovators and users/beneficiaries reveal rigorous proactiveness and responsiveness of innovation creators and users in the three countries – reflected in numerous attestations of life transformation. Nevertheless, there is a paradigm shift in the diffusion of innovations amongst users – contrary to the discourse around its early precepts.

This study aims to examine the determinants of adoption intention toward the rooftop solar photovoltaic (RSPV) systems among residents of peri-urban villages of Gurugram, Haryana, India. This study also analyzes the impact of the adoption of RSPV systems on carbon neutrality from a behavioral perspective.

Data was collected using a self-administrated structured questionnaire from 208 male villagers (195 usable) of 22 villages using the purposive sampling technique.

Results revealed that relative advantage, followed by simplicity, trialability, observability and compatibility, positively and significantly impact villagers’ attitude toward adopting RSPV systems in their homes. Perceived severity and perceived vulnerability significantly influence the perceived behavioral control of villagers toward adopting the RSPV systems. The results show villagers’ attitudes, subjective norms and perceived behavioral control are the essential predictors of their adoption intention of the RSPV systems. Most notably, carbon neutrality was significantly affected by villagers’ adoption intention of RSPV systems as the renewable energy source in their homes.

The findings of this study provide that innovation attributes are important factors in shaping the adoption intentions of customers toward RSPV systems. This study is also the extent of previous studies measuring customers’ perception of adopting renewable energy in developed and emerging countries worldwide.
