IntroductionElectric power plays a vital role in the development of the South African economy. Historically, South Africa relied primarily on coal for electricity generation, making the power sector one of the largest emitters of greenhouse gases(), however, these countries have enormous potential to produce more electricity. clean using renewable resources. The current challenge is that these sources are still very expensive and coal remains the cheapest source for generating electricity (Kinghorn, 2014). This report will discuss the supply of electric energy, its demand, challenges and the future energy mix in the South. Africa, a conclusion will be drawn from the facts and opinions discussed in the report. "It is based on the presentation made by Mr AJ Kinghorn on 24 April 2014 to fourth year mining engineering students at the University of the Witwatersrand. Energy SupplySouth Africa produces more than half of the electricity used on the African continent and has three electricity generator groups: the national electricity utility, municipal generators and automobile generators, and industries that produce electricity for their own use (UCT, 2006). the state-owned company that supplies and produces 95% of the national public electricity in South Africa, with the remaining percentage going to industries producing for their own use and to municipalities (Ner, 2001 Electricity Generation in Africa). The South's electricity comes largely from conventional coal-fired power stations. South African coal deposits are found in Mpumalanga Province, Gauteng, Limpopo and the Free State. These have therefore led to the construction of power stations around these areas, as transporting coal over long distances can be expensive. More than 92% of the world's population relied primarily on coal for electricity generation, making the electricity sector one of the largest emitters of greenhouse gases. Eskom, which is the state-owned utility that supplies 95% of the national public electricity in South Africa. Electricity generation in South Africa comes largely from conventional coal-fired power stations and other forms of generation come from nuclear power station, gas turbines and hydroelectric power which is entirely owned by Eskom. The demand for electricity has reduced electricity reserve margins, industries are the largest demanders of electrical energy, coal pollutes not only the air but also the water, and nevertheless it will always be used as the main source of electrical energy due to its availability and low cost. But the Integrated Resources Plan 2010 to 2030 emphasizes that dependence on coal would decrease by 2030
