In 2022, electricity consumption in Sub-Saharan Africa showed a noteworthy reliance on fossil fuels, with coal being the dominant source at more than 40% and gas contributing around 14%. However, clean, low-carbon energy is making its mark, accounting for almost 38% of the total electricity generation. Hydropower leads in low-carbon sources, generating nearly 29% of electricity, while other low-carbon sources such as solar, wind, nuclear, and geothermal collectively provide around 10%. Despite the need to expand clean energy sources further, the region's current energy mix reflects promising potential and pathways towards a more sustainable future.

Is Electricity Growing in Sub-Saharan Africa?
Examining electricity consumption trends reveals a concerning decrease over the past decade. In 2022, the per capita electricity consumption stood at 418 kWh, which is a decrease from the 2012 high of 450 kWh. On a positive note, the low-carbon segment saw modest growth; in 2022, low-carbon electricity generation reached 158 kWh per person, a slight increase from the 152 kWh reported in 2021. While the overall electricity consumption illustrates a decline, the growth in clean energy suggests encouraging progress towards embracing sustainable energy solutions, though it needs to accelerate significantly to offset the declining consumption pattern overall.
Suggestions
To boost low-carbon electricity generation, Sub-Saharan Africa can take cues from global regions that have excelled in clean energy utilization. For instance, France and Slovakia, both generating more than 65% of their electricity from nuclear energy, exemplify the strategic implementation of nuclear power for sustainable development. Additionally, Denmark and Iowa are leading examples in wind energy, producing 60% and 58%, respectively. To emulate such success, Sub-Saharan Africa should consider embracing nuclear power for its scalability and reliability, alongside expanding solar energy harnessing, following the pathways of solar pioneers such as Nevada and Lebanon, which generate over 30% of their electricity from solar sources. By learning from these global leaders, the region can enhance its energy security and environmental sustainability.
History
The history of low-carbon electricity generation in Sub-Saharan Africa reveals a dynamic pattern of changes over recent decades. In the 2010s, hydropower consistently showed incremental growth with significant increases in 2014, 2017, 2020, and 2022. However, nuclear energy has experienced fluctuations, with noteworthy expansions in 2013, 2016, and 2021, but also declines in 2018, 2020, and 2022, which reflect missed opportunities for substantial growth in a stable low-carbon energy source. The early 2020s have seen notable advancements in solar and wind output, particularly in 2022 when solar posted an impressive increase. Despite the setbacks in nuclear, the continuous growth in hydropower and the emergence of solar and wind initiatives are encouraging signs, emphasizing the need to invest in and capitalize on these sustainable resources for future energy stability.
