South Africa has several suitable renewable energy sources beyond the widely used solar and wind power that could help diversify its energy mix and support sustainable development:

• Biomass Energy : South Africa's agricultural and forestry sectors produce significant organic waste that can be converted into biogas or used directly for biomass power generation. Biomass offers a sustainable and locally available energy source that can complement solar and wind

• Hydropower : Although large-scale hydropower potential is limited, small-scale hydropower projects utilizing rivers and streams could be developed in certain regions to provide additional renewable electricity

• Geothermal Energy : South Africa has some geothermal potential in specific areas. While currently less prominent, geothermal energy could provide a consistent baseload power supply, helping to stabilize the grid alongside intermittent solar and wind sources

In summary, alongside the dominant solar and wind resources, biomass, small- scale hydropower, and geothermal energy represent other renewable options suitable for South Africa's energy transition. These sources can enhance energy security, reduce reliance on coal, and support economic growth through job creation and local industry development
