    Climate shocks, adaptive mechanisms and household energy transition in Uganda
    (Springer International Publishing, 2024-11) Elasu, Joseph; Ntayi, Joseph Mpeera; Adaramola, Muyiwa S.; Buyinza, Faisal; Atukunda, Ronnette; Ngoma, Muhamad
    Abstract Nearly 41% of the global populace depends on unclean fuels for cooking. As a result, about 4 million premature deaths connected to household air pollution are registered annually. Worryingly, over 2.1 billion people are estimated to continue using unclean fuels by 2030 if no strong policy actions are taken to alter the status quo. Climate parameters including; temperature, solar radiation, wind, and moisture have been widely touted as having an impact on multidimensional energy poverty, their effect on household energy consumption and subsequent transition to cleaner fuels is seldom investigated in Uganda. The purpose of this study is to investigate the effect of climate shocks, and adaptation mechanisms on household energy transition in Uganda. The study adopted a panel data methodology employing an ordered logit model with random effects to estimate the effect of climate shocks and adaptation mechanisms on household fuel transition from high to low-pollutant cooking fuels in Uganda. The findings revealed that climate shocks, adaptation mechanisms significantly affect household energy transition in Uganda. The study recommended that policies aimed at enhancing detection and report of early warning signs should be emphasized. Furthermore, investing in an insurance scheme especially for people living in climate shock prone areas can help households to cope up with shocks are eventually transition to clean cooking fuels.

    Conceptualization and antecedents of productive use of electricity: A systematic literature review
    (Cleaner Engineering and Technology, 2024-04-28) Aarakit, Sylvia M.; Ntayi, Joseph M.; Wasswa, Francis; Buyinza, Faisal; Adaramola, Muyiwa S.
    Productive use of energy is recognized as a pathway to economic and sustainable development. Indeed, there has been deliberate effort to promote productive use of energy, particularly, electricity by policy makers and international organizations. However, limited understanding of what constitutes productive use and factors that potentially influence uptake of productive uses at micro level continue to undermine existing efforts to promote productive use of energy in developing countries. Using a systematic literature review approach, a total of 54 out of 997 articles were selected following the criteria for inclusion and exclusion for further analysis. We find that majority of studies define productive use of electricity as application of electricity energy services to activities that generate income or enhance productivity. Regarding conceptualization, we found that productive use of electricity is conceptualized along three dimensions, which are (1) improved performance of existing income generating activities, (2) use of modern electrical productive use appliances and (3) creation of new enterprises and job opportunities after electrification. Furthermore, the review found that majority of studies identify electricity related factors as important drivers of productive use of electricity. However, these should be bundled with other non-electricity related variables including financial, technological, human capabilities, institutional, infrastructural, social, demographic characteristics. The paper has also identified various research gaps that may inform future studies in productive use of electricity.

    Effects of technical and security factors on grid electricity reliability: evidence from Uganda national electricity grid network
    (Emerald, 2023-11-03) Migisha, Adella Grace; Ntayi, Joseph Mapeera; Adaramola, Muyiwa S.; Buyinza, Faisal; Senyonga, Livingstone; Abaliwano, Joyce
    Purpose An unreliable supply of grid electricity has a strong negative impact on industrial and commercial profitability as well as on household activities and government services that rely on electricity supply. This unreliable grid electricity could be a result of technical and security factors affecting the grid network. Therefore, this study aims to investigate the effects of technical and security factors on the transmission and distribution of grid electricity in Uganda. Design/methodology/approach This study used the ordinary least squares (OLS) and autoregressive distributed lag (ARDL) models to examine the effects of technical and security factors on grid electricity reliability in Uganda. The study draws upon secondary time series monthly data sourced from the Uganda Electricity Transmission Company Limited (UETCL) government utility, which transmits electricity to both distributors and grid users. Additionally, data from Umeme Limited, the largest power distribution utility in Uganda, were incorporated into the analysis. Findings The findings revealed that technical faults, failed grid equipment, system overload and theft and vandalism affected grid electricity reliability in the transmission and distribution subsystems of the Ugandan power grid network. The effect was computed both in terms of frequency and duration of power outages. For instance, the number of power outages was 116 and 2,307 for transmission and distribution subsystems, respectively. In terms of duration, the power outages reported on average were 1,248 h and 5,826 h, respectively, for transmission and distribution subsystems. Originality/value This paper investigates the effects of technical and security factors on the transmission and distribution grid electricity reliability, specifically focusing on frequency and duration of power outages, in the Ugandan context. It combines both OLS and ARDL models for analysis and adopts the systems reliability theory in the area of grid electricity reliability research.

    Investigating the modern renewable energy-environmental Kuznets curve (REKC) hypothesis for East Africa Community (EAC) countries
    (Emerald, 2023-11-28) Nabaweesi, Jennifer; Kigongo, Twaha Kaawaase; Buyinza, Faisal; Adaramola, Muyiwa S.; Namagembe, Sheila; Nkote, Isaac Nabeta
    Purpose The study aims to explore the validity of the modern renewable energy-environmental Kuznets curve (REKC) while considering the relevance of financial development in the consumption of modern renewable energy in East Africa Community (EAC). Modern renewable energy in this study includes all other forms of renewable energy except traditional use of biomass. The authors controlled for the effects of urbanization, governance, foreign direct investment (FDI) and trade openness. Design/methodology/approach Panel data of the five EAC countries of Burundi, Kenya, Rwanda, Tanzania and Uganda for the period 1996–2019 were used. The analysis relied on the use of the autoregressive distributed lag–pooled mean group (ARDL-PMG) model, and the data were sourced from the World Development Indicators (WDI), World Governance Indicators (WGI) and International Energy Agency (IEA). Findings The REKC hypothesis is supported for modern renewable energy consumption in the EAC region. Financial development positively and significantly affects modern renewable energy consumption, whereas urbanization, FDI and trade openness reduce modern renewable energy consumption. Governance is insignificant. Originality/value The concept of the REKC, although explored in other contexts such as aggregate renewable energy and in other regions, has not been used to explain the consumption of modern renewable energy in the EAC.
