Abstract

The management of energy generally focuses on point-of-use consumption, specifically on those of the actual vehicles used. In order to reduce the total system consumptions and to take energy management into the future, energy supply and consumption needs to be investigated holistically on a systematic level. Energy consumption is generally directly proportional to greenhouse emissions. This is particularly relevant to South Africa where the majority of all energy consumed is fossil fuel-based. Included in this is the electricity used by the various facilities that are used by the rail industry. The feasibility of reducing fossil fuel-based energy consumption, at rail facilities forms the basis of this article. In order to reduce the fossil fuel-based energy consumption either the amount of energy consumed, or the type of energy consumed or both need to change. Financial feasibility of any such shift is a key component to encourage industry to adopt these recommendations. In order to validate the financial feasibility of the recommendations a case study that was performed at the Salt River maintenance facilities of Metrorail, Cape Town, South Africa, is discussed.
