Understanding the nexus between energy and water: A basis for human survival in South Africa

Despite the fact that the South African economy is highly diversified, the sustainability of its economic growth depends on the availability of two critical resources: water and energy. The national energy grid is mostly based on coal combustion, with very few viable alternative resources. Large amounts of water are needed to produce energy from coal and, in most places where coal reserves are located, there is evidence of water scarcity. The sustainable management of both sectors is essential, since research has shown that access to potable water and energy will lead to a better quality of life for people and help alleviate poverty. This paper will focus on the interlinkages and understanding of the trade-offs between water and energy and its implications for sustainable development in South Africa. The simultaneous implementation of selected Sustainable Development Goals targets could help reduce the trade-off between the two sectors.
