Do solar water heaters improve access to hot water and reduce electricity costs? : the complexities of implementing energy poverty interventions in South African Townships : a case study of Nyanga Township
Solar energy is abundantly available in South Africa, but it is a highly under-utilised resource. One way of efficiently using the resource is solar water heating (swh), a natural process whereby hot water for domestic and/or industrial use is heated by the sun. In 2009, a national swh strategy was …
