In Sub-Saharan Africa, the current state of electricity consumption heavily leans on fossil fuels, which account for a little over 60% of the electricity generation. Coal, as the major contributor within this group, provides almost 41% of the total. Low-carbon or clean energy sources, while trailing its fossil counterpart, form a significant portion by contributing nearly 38% to the electricity mix. This low-carbon segment includes hydropower as the leading clean energy source making up about 29%, while solar and wind add just over 3% and slightly over 2.5%, respectively. Nuclear and geothermal energy are the least common low-carbon sources in the region, contributing close to 2% and a little over 1%, respectively. The reliance on fossil fuels poses environmental threats through emissions contributing to global climate change, underlining the need for a transition towards cleaner energy.

Is Electricity Growing in Sub-Saharan Africa?
Electricity consumption per person in Sub-Saharan Africa currently stands at 418 kWh as of 2022. This figure, unfortunately, marks a decline from the peak last recorded in 2012 at 450 kWh per person. This drop of 32 kWh per person raises concerns about stagnation in electricity access, particularly when electric power is crucial for economic development and quality of life. However, there is a silver lining in the growth of low-carbon electricity consumption, which reached a record 158 kWh per person in 2022, up from the previous high of 152 kWh per person in 2021. This increase in low-carbon electricity, albeit modest, is a step in the right direction and indicates a growing adoption of sustainable energy solutions.
Suggestions
To significantly accelerate the growth of low-carbon electricity generation in Sub-Saharan Africa, there are valuable lessons to be gleaned from regions with successful clean energy integration. Notably, countries like Denmark and Iowa have integrated wind power to supply 60% and 58% of their electricity, respectively. Nuclear, while less common in the region, could also be pivotal; examples from France, where nuclear energy accounts for 67%, indicate its potential for substantial and reliable low-carbon power generation. Encouraging investment in solar energy, as seen in Nevada's 34% solar electricity generation, could leverage the abundant sunlight in many parts of Sub-Saharan Africa. These initiatives would help mitigate reliance on fossil energy, reduce emissions, and move towards a sustainable energy future.
History
In the historical context, Sub-Saharan Africa's journey of low-carbon electricity generation has seen both progress and setbacks. Starting in 2013, hydropower was on a steady rise with regular annual increases, apart from minor contractions in 2015. A significant boost was observed in 2022 with an increase of over 8 TWh. Wind and solar energies have also been growing with notable increases in recent years, particularly in 2022 when solar energy saw a noteworthy rise of 4.9 TWh. However, nuclear energy has faced inconsistencies, with recent years showing considerable declines, such as in 2018 and 2020. Despite these setbacks, nuclear remains a vital part of the region’s clean energy mix, and with strategic planning and investment, its potential can be fully harnessed to complement the other growing low-carbon sources. This pattern shows the region's potential in renewable sector and sets a promising path towards energy sustainability.
