In South Africa's electricity landscape for the year 2024, fossil fuels still dominate the generation mix, with more than four-fifths of the electricity being derived from fossil energy. Coal is the primary source within this category, contributing a significant portion of the total consumption. Despite this heavy reliance on coal, the share of low-carbon energy in South Africa's electricity generation mix stands at about 16%. Within the low-carbon category, solar contributes to almost half of the clean energy share, while wind provides almost a third, and nuclear energy contributes slightly more than 3%. The increasing penetration of solar power is notable among South Africa's low-carbon energy sources.

Is Electricity Growing in South Africa?
Examining the growth of electricity consumption in South Africa reveals a concerning decline compared to historical records. As of 2024, the total electricity consumption per capita is around 3675 kWh, a significant drop from the historic high of 5214 kWh per person in 2007. This reduction of nearly 30% indicates stagnation in the electricity growth needed to support development and electrification. On a positive note, low-carbon electricity generation per capita has climbed slightly to 586 kWh from the previous year's record, reflecting a modest yet encouraging 19 kWh increase. This small uptick highlights an opportunity for further transition to renewable sources to spur overall electricity growth.
Suggestions
To bolster low-carbon electricity generation, South Africa can draw lessons from regions with similar energy profiles and environmental conditions. Expanding solar infrastructure in areas with high solar irradiance, like California, which generates nearly a third of its electricity from solar, could be highly beneficial for South Africa. Additionally, adopting successful nuclear strategies from countries like France and Slovakia, where nuclear accounts for more than half of their electricity generation, could substantially increase South Africa's low-carbon output. Implementing such strategies would help to reduce the country's reliance on fossil fuels, thereby minimizing environmental impacts such as air pollution and contributing positively to climate change mitigation efforts.
History
Looking back at the history of low-carbon electricity in South Africa, there have been alternating periods of growth and decline, particularly concerning nuclear energy. The mid-1980s saw substantial growth in nuclear power, with significant increases in 1984 and 1986. However, this was followed by declines in subsequent years, notably in 1987, 1990, and the early 2000s. Sporadic support for nuclear energy can also be seen with declines in 2001 and 2005. In recent years, nuclear energy saw brief revivals, as in 2021. More recently, solar energy has emerged as a significant contributor, with steady growth, especially noticeable in 2022 and 2023. The persistence of these variances underlies the potential and necessity for a stronger, more consistent commitment towards bolstering South Africa's low-carbon electricity network, particularly through nuclear and solar investments.
