In 2024, South Africa's electricity consumption remains heavily reliant on fossil fuels, with coal dominating the landscape at 82% of the total mix. This reflects the country's longstanding dependence on coal-fired power plants, which have significant implications for both air quality and greenhouse gas emissions. On a more positive note, clean energy sources, such as solar, wind, and nuclear, account for just over 17% of the total electricity production. Solar power contributes 8.5%, while wind energy supplies close to 5%. Meanwhile, nuclear energy, which stands as a powerful source of low-carbon electricity, represents a little over 3% of the total, demonstrating the potential for further expansion in South Africa’s clean energy portfolio.

Is Electricity Growing in South Africa?
Despite efforts to integrate low-carbon sources, overall electricity consumption in South Africa has not seen a similar upward trajectory. Currently, the per capita consumption is 3674 kWh, a decline from the 2007 peak of 5214 kWh. This suggests that the total electricity availability has decreased by about 1540 kWh per person since then. In contrast, there is a positive trend in terms of low-carbon electricity generation, which has increased to 628 kWh per person, a slight improvement from the previous year’s record. While progress is being made in clean electricity, the overall reduction in electricity consumption raises concerns about meeting future demands driven by electrification and technological advancement.
Suggestions
To bolster low-carbon electricity generation, South Africa can look to successful regions for inspiration. Countries like France and Slovakia generate more than half of their electricity from nuclear power, showcasing the viability of nuclear expansion. Similarly, states such as Nevada and California demonstrate effective solar power integration, with solar contributing approximately a third of their electricity. South Africa could strategically enhance its solar and nuclear capacities, drawing lessons from these regions to not only meet its electricity needs but also reduce its carbon footprint and reliance on fossil fuels.
History
Historically, South Africa's journey with low-carbon electricity has experienced varied progress. The 1980s saw fluctuations in nuclear output, with notable increases followed by declines, reflecting an inconsistency in nuclear integration that persisted into the early 21st century. Recent years, however, show a promising growth in solar power, with significant increases in 2022 and 2023. While the nuclear sector has seen occasional setbacks, the uptick in solar suggests a growing commitment to harnessing sustainable sources. Moving forward, South Africa should strive to capitalize on these clean energy expansions while learning from past challenges to create a more resilient and sustainable energy future.
