The dramatic fall in the cost of supplying power from wind and solar photovoltaic (PV) plants has moved the global electricity supply industry beyond a critical “tipping point”, which leading energy scientist Dr Tobias Bischof-Niemz says is irreversibly altering the operating model, with significant implications for sun-drenched and wind-rich South Africa.
Instead of renewable energy playing only a modest and supportive role in the future supply mix, research conducted by the Council for Scientific and Industrial Research (CSIR) Energy Centre shows that, having the bulk of the country’s generation arising from wind and solar is not only technically feasibly, but also the lowest-cost option.
