MASTER'S THESIS

The South African economy strongly depends on the consumption of fossil fuels such as coal as the primary energy source countrywide. Although other renewable potential, such as that which is possessed by hydropower and solar irradiance, as well as by wind power, is vast, it is, as yet, almost untapped.
