One of the fundamental aspects of any economy is the availability and provision of sustainable energy. This is because it forms the central part of social, environmental and economic challenges in any country. Most governments worldwide, are now considering locally accessible, available, and renewable substitute energy options to address the concernsof emissions of greenhouse gases, climatechange impacts and the necessity for the provision of cleaner energy. Reliance on fossil fuels for energy provisions is well documented. South Africa thus depends largely on coal as the core energy source contributing about 77%, with 92% production of thetotal coal consumed on the continent. Biogas, as an alternative is a renewable and sustainable energy source that can offer green energy. Biogas has proven to be a promising, realistic and feasible technology in providing clean and reliable energy. This paper, therefore, aims at presenting the potentials and status of biogas utilization, the technological associated benefits, future prospects and lingering challenges in South Africa.
