Integrating household energy needs and agricultural productive uses in energy planning can enhance economic development in Sub-Saharan Africa

Abstract

Sub-Saharan Africa (SSA), with one of the fastest-growing populations in the world, is experiencing rapid urbanization and the emergence of a growing middle class. However, agricultural production falls short of meeting the projected food demand, hindered by a lack of access to modern energy. Improving the productivity of smallholder farmers and expanding local crop processing are vital strategies for addressing food security and improving the livelihoods of farmers. Supplying electricity for irrigation and crop processing can stimulate entrepreneurship, foster local wealth creation, and support the achievement of several Sustainable Development Goals, while improving the cost-effectiveness of clean energy plans in rural areas. This article argues that Africa's energy planning should prioritize clean and modern energy solutions aimed at accelerating economic growth extending beyond basic household services. The argument applies specifically to rural smallholder contexts in SSA, typically served by mini-grids or off-grid systems. Drawing on a synthesis of recent literature and illustrative projects from rural Tanzania, this manuscript shows that the benefits of productive energy use extend beyond mechanizing agriculture and crop processing. These initiatives enhance local economic development by integrating electricity into household business operations, such as milling and agro processing, which create jobs and diversify income, while acknowledging that local context, water governance and market access critically shape outcomes. They also enhance communication and provide critical market information, empowering rural communities. By prioritizing productive energy uses, these projects increase electricity consumption, improving the financial sustainability of electrification efforts.
