Renewable energy sources are way cheaper than fossil fuels like coal and nuclear.
This is according to a recent presentation by the head of CSIR's Energy Centre, Dr Tobias Bischof-Niemz, and Ruan Fourie, energy economist at CSIR's Energy Centre.
Power utility Eskom supports getting power from independently-run coal projects rather than renewable sources as the state-owned company expects current generation will be insufficient to meet demand by 2022.
Energy minister Tina Joematt-Pettersson recently announced the successful bidders for the first coal-based independent power producer (IPP) programme. Coal is SA's dominant energy source, with 77% of the country's energy needs being provided by this mineral.
SA is also proceeding with plans to expand nuclear as a source of energy, although the issue has been contentious amid allegations that individuals close to the president and groups linked to the ruling ANC have significant financial interests in the matter.
