A second independent study by the Council for Scientific and Industrial Research (CSIR) found that renewable energy from South Africa's first wind and solar (photovoltaic) projects created R4 billion more financial benefits to the country than they cost during the first six months of 2015. This is including the costs of avoided load shedding when solar and wind energy supplied power when the system would otherwise have had to go into load shedding.
For a general overview of findings see the CSIR media release, for specifics, see the CSIR’s presentation on the findings.
