Analysis
The most recent figure for electricity generation from low-carbon sources in South Africa is 43.31 terawatt-hours, measured in 2025. That is the highest value across all 55 years on record.
Compared with earlier readings it is up 11.7% on the previous year and up 130.9% over ten years.
Over the whole period, electricity generation from low-carbon sources in South Africa peaked at 43.31 terawatt-hours in 2025 and was at its lowest, 0.112 terawatt-hours, in 1971.
That places South Africa 36th out of 209 countries with data for 2025, putting it in the top quarter.
The series is highly variable year to year, so single readings are best treated with caution.
