Cutting down electricity usage can help save costs for SA school - study reveals By The Conversation Jason Avron Samuels,Leslie van Rooi, MJ (Thinus) Booysen and Sara Grobbelaar Despite financial constraints, high costs and the best efforts of principals, electricity usage in South Africa’s schools remains largely unchecked, as schools focus on educational outcomes. The country’s 23,471 public schools use an estimated 3.5 TWh of energy a year. This is about a quarter of Koeberg nuclear power station’s production and it costs about R5 billion ($330 million). In a recent study we analysed the energy usage of 13 schools in Stellenbosch, a town in South Africa’s Western Cape province. The sample included poor and affluent schools. We then compared it with what schools use in other countries. This comparison makes it possible to estimate energy efficiency and see where money can be saved.
