Combining panel data econometrics (2000–2022), geospatial analysis, and policy evaluation, we find that renewable energy adoption drives significant LCF improvements, with a 1% increase in renewable share boosting LCF by 0.12 points (p < 0.01). Fossil fuel efficiency gains, while beneficial, prove half as effective. Morocco's integrated solar strategy (+10.2% LCF) and Kenya's geothermal expansion (+4.7% LCF) demonstrate how targeted renewable investments enhance sustainability, whereas Nigeria's governance failures (-15.0% LCF) and South Africa's coal dependence (-8.9% LCF) reveal institutional and technological lock-in challenges. Crucially, policy quality emerges as a decisive factor: strong governance regimes triple renewable energy's impact compared to weak ones. Urbanization pressures offset 30% of renewable gains, highlighting the need for complementary sustainable urban planning. The study challenges conventional transition models by showing no automatic LCF recovery at higher income levels—unlike Asian experiences— emphasizing Africa's need for proactive, context-sensitive policies. It was recommended among others that governments must implement enforceable renewable energy policies with clear accountability mechanisms. Moreso, energy transitions should be systematically integrated with sustainable urban development strategies to mitigate ecological pressures. Keywords: Load capacity factor, energy transition, renewable energy, Africa, environmental sustainability, policy governance Introduction The pursuit of environmental sustainability has emerged as a critical imperative for developing nations, particularly in Africa, where rapid population growth, urbanization, and industrialization intersect with acute energy poverty and climate vulnerability (IPCC, 2022). Unlike industrialized economies, many African countries face a dual challenge: addressing energy deficits that hinder socio- economic development while mitigating environmental degradation linked to conventional energy systems (IEA, 2022). In this context, the interplay between non-renewable energy efficiency and renewable energy adoption has gained prominence as a pathway to reconcile economic growth with ecological preservation. However, the effectiveness of such strategies remains contested, particularly in resource-dependent economies where fossil fuels and biomass dominate energy matrices (Bhattacharya et al., 2020). This study investigates the role of non-renewable energy efficiency and renewable energy deployment in advancing environmental sustainability across four African nations Kenya, South Africa, Morocco, and Nigeria through the lens of the Load Capacity Factor (LCF) hypothesis. By evaluating biocapacity and ecological footprint dynamics, the analysis seeks to unravel how these countries can navigate the tension between energy security, economic development, and planetary boundaries. The LCF hypothesis, introduced by Gürlük (2009), offers a nuanced framework to assess environmental sustainability by comparing a region’s biocapacity (its ability to regenerate resources and absorb waste) with its ecological footprint (the de mand placed on ecosystems). Unlike conventional metrics such as carbon emissions or energy intensity, the LCF provides a holistic measure of ecological balance, making it particularly relevant for African nations where biodiversity loss, deforestation, and soil degradation exacerbate climate risks (Alola et al., 2023). For instance, Kenya’s reliance on biomass for 68% of its energy needs has accelerated deforestation, reducing its biocapacity by 12% since 2000 (KNBS, 2021). Conversely, Morocco’s Noor Ouarzazate Sol ar Complex one of the world’s largest concentrated solar power plants has reduced its ecological footprint by displacing 1.3 million tons of CO2 annually (World Bank, 2023). Such contrasts underscore the urgency of understanding how energy transitions influence
