Assessing wind energy development in Uganda: Opportunities and challenges
(Sage Journals, 2021-12-06) Wabukala Benard M; Otim Jacob; Mubiinzi Geoffrey; Adaramola Muyiwa S.
In this paper, we utilize a systematic review to assess opportunities and challenges in wind energy development in Uganda. Apart from being an environmentally friendly and renewable energy resource, development of wind energy could boosts economic growth and creates jobs. For Uganda, rising energy demand, need to reduce greenhouse gas emissions, and increasing electricity access to rural areas, emerge as rational opportunities to invest in wind energy. The main obstacles to wind energy development in Uganda are insufficient wind resource data, high initial investment cost, inadequate research and development, weak infrastructure, and unsupportive policies. For policy, comprehensive wind resource assessment, energy infrastructure investment, financial de-risking, capacity building, and deliberate wind power policy incentives could accelerate wind energy development and consequently contribute to the country’s energy security.
Economic growth through gender parity: evidence from education, labour, and governance in Uganda
(Science Direct, Elsevier, 2025-04-19) Mubiinzi Geoffrey; Ssebabi Mutumba Geoffrey
This study examines the extent to which gender parity in education, labour force participation, and governance influences Uganda's economic growth. It investigates whether progress in these dimensions of gender equality leads to sustained economic benefits by analysing both short- and long-run effects using an Autoregressive Distributed Lag (ARDL) model and annual data from 1997 to 2023. The results reveal contrasting effects: while educational parity has a positive but statistically insignificant long-run impact, suggesting that increased female enrolment alone is insufficient for economic transformation, labour force parity exerts a significant negative long-run effect due to structural inefficiencies, such as occupational segregation and under-employment. By contrast, governance parity, measured by female representation in parliament, demonstrates a significant short-run positive effect, indicating that inclusive decision-making can yield immediate economic gains, although its long-run effect remains statistically insignificant due to institutional constraints. These findings highlight the need for structural reforms to enhance the quality of female employment, institutional governance effectiveness, and the alignment between education and labour market demands. Policymakers should prioritize gender-sensitive policies that foster productive employment, strengthen governance reforms, and improve economic returns on educational parity to maximize the contribution of gender equality to economic growth. This study provides empirical evidence supporting gender-inclusive economic strategies, offering valuable insights for Uganda and similar economies in sub-Saharan Africa.
Efficient tariff system in the electricity distribution: evidence from Uganda
(Sciencedomain International, 2024-03-27) Ssebabi Mutumba Geoffrey; Amerit Bosco; Kaddu Milly; Mubiinzi Geoffrey; Bashir Hassan; Birungi Felister; Nakajubi Florence; Jaza Muhamood; Senyonga Livingstone
This study investigates incentive regulation to foster an efficient tariff system in the electricity distribution subsector in Uganda. This study seeks to find empirical evidence to support the argument that regulation is associated with efficiency among distributors. It seeks to design an appropriate model of incentive regulation within the distribution subsector. It assesses the efficiency of existing tariff setting system with a view of guiding policy on how best incentives should be appropriated. It uses the data envelopment analysis and stochastic frontier analysis to investigate how distribution firms use input costs to come up with an efficient end user tariffs. Quarterly data used is from Electricity Regulatory Authority (ERA) covering the period 2013-2019. The findings are that distribution firms cost inputs are inconsistent with the way they their operational and maintenance costs are generated and transmitted to end user tariff. The regulator should be keen on the way tariff is set such that it is fair to all players in the electricity markets. Incentive regulation has a positive influence on cost efficiency and end user tariff. A reduction in energy losses and energy purchases from transmitter makes up the most efficient cost drivers. Lastly, tariff regulation has increased efficiency in operations through in improved quality and reliability of power distribution. First and foremost is reduced load shedding, secondly is more reliable power distribution to end users. Appropriate Incentive regulation has a direct effect on cost of utility and in increasing access of vulnerable groups.
Electricity consumption and economic growth: evidence from the East African community
(Elsevier, Science Direct, 2024-07) Ssebabi Mutumba Geoffrey; Mubiinzi Geoffrey; Amwonya David
This study investigates the dynamic causal relationship between electricity consumption and economic growth in the East African Community (1990–2021). It seeks to interrogate the nature of relationship between electricity consumption and economic growth. The hypothesis used in this study is four folded including growth, conservation, feedback and neutral hypothesis. It uses panel data estimation techniques, particularly the panel dynamic ordinary least squares (DOLS), fully modified ordinary least squares (FMOLS), and non-linear autoregressive distributed lag (NARDL). The panel augmented Dickey Fuller (ADF)-fisher and Levin, Lin & Chu (LLC), 2003, was used to test the unit root process. Dumitreschu-Hurlin (2012) and pairwise Granger tests were used to test for the direction of causality. The findings indicate growth hypothesis with a unidirectional relationship running from electricity consumption to economic growth. Regional governments must increase their investments in electricity market trading to boost economic growth. Greater benefits from regional cooperation can be realized with increased investment in electricity consumption. This is a novel study of the dynamic causal relationship between electricity consumption and economic growth in the East African Community. It is a ground-breaking inquiry into the possibility of integrating electricity markets and their role in promoting economic growth.
Income and price elasticities of household electricity demand: a comparative systematic review of aggregated and disaggregated data studies
(Elsevier, Science Direct, 2024-12) Mubiinzi Geoffrey; Senyonga Livingstone; Kigongo Kaawaase Twaha; Wasswa Francis; Adaramola Muyiwa S.; Nantongo Maria
This systematic review investigates disparities in research coverage and assesses the implications of income and price elasticities on household electricity demand. By analyzing studies across various regions and income groups, it aims to uncover imbalances in research distribution and understand their impact on energy policy development. The review employs a systematic approach, analyzing peer-reviewed and gray literature from Scopus, Web of Science, and Google Scholar databases from 1980 to 2023. It addresses four research questions: regional and income group classifications, differences in income elasticities, variations in price elasticities, and the accuracy and variability of household electricity demand elasticity estimates between aggregated and disaggregated data studies. The review reveals significant imbalances, with the Middle East, North Africa, and Sub-Saharan Africa underrepresented, while Europe and Central Asia exhibit robust research. Consistent inelasticity in electricity demand is observed across contexts and timeframes. High-income countries dominate this research, leading to a lack of empirical studies in low-income regions, hindering tailored interventions. Understanding short- and long-run elasticities is crucial for effective demand forecasting and policy design. This review uniquely compares income and price elasticities from aggregated and disaggregated data studies, highlighting regional research disparities and their implications for energy policy. It emphasizes the need for inclusive, context-specific investigations to foster sustainable development and equitable energy access globally.
