The selection of renewable energy technologies and their cost implications for a developing country : the case of South Africa

Abstract: Renewable energy technologies have to be considered and appropriately supplemented in the energy mix. For this mini-dissertation, particular emphasis will be focusing on the developing nation of South Africa. Research previously conducted has indicated there are specific key criteria to consider for selecting sustainable energy methods, particularly for renewable energy technologies in Africa. Within this mini-dissertation consideration is given to renewable energy methods for generating power in South Africa from selected viewpoints that consist of political, social, technical, economic and environmental impact. With the aid of the Analytic Hierarchy Process (AHP), this particular mini-dissertation will allow for selecting and prioritizing various renewable technologies for power generation. Potential for electricity generation was accessed from renewable resources, reviewing of relevant scholarly literature and discussion with experts; an appropriate decision-model has been utilised consisting of goal, criteria, sub-criteria and alternatives. Onshore wind energy, solar photovoltaic, concentrated solar thermal, biomass and small hydro energy options are used as the alternatives in the decision model. The mini-dissertation makes use of a real-world case study within South Africa, to apply the decision-model, build upon previous research and showcase its value in energy planning. In addition to prioritisation and ranking of these alternatives to show the best technology will be that of solar energy for the South African market; results of the proposed decision model can also be used to advocate in developing specific policies and energy roadmaps for the country.M.Ing.
