Could wave power be an answer to SAs electricity crisis

South Africa has a 2800-km long coastline with high wave energy potential that can generate electricity. Presenting a lecture at the UFS Department of Geology, Prof Stoffel Fourie discussed wave power as a possible solution to the country’s electricity needs. Prof Fourie is a geophysicist and the chairperson of research and development in the faculty of engineering at Walter Sisulu University.

Power at any time
Wave power is a renewable and sustainable resource. “It can provide continuous base load power because wave energy systems do not suffer from ‘time of day’ issues as other renewable energy options. This means that it can generate power at any time of the day,” said Prof Fourie. 
Discussed also was the wave power advantages and disadvantages. 

Wave energy advantages
• Wave energy is a reliable renewable energy resource;

• Reduces dependency on fossil fuels;

• Wave energy is predictable and consistent;

• Generates little or no pollution to the environment compared to other energy resources; and

• Presents no barriers or difficulty to migrating fish and aquatic animals.

Wave energy disadvantages
• Wave energy conversion devices are location dependent, thus limiting possible sites where they can be implemented;

• Offshore wave energy devices can be a threat to shipping as they are too small to detect by radar; and

• High capital investment required for start-up costs, construction and maintenance.

“Looking at both advantages and disadvantages, there is no doubt that South Africa can use this method to harvest energy. With the right investment and political buy-in, wave power could provide a continuous supply of energy and contribute to all South Africa’s electricity needs,” Prof Fourie said.

In view of the environmental and social problems faced in South Africa today, researchers such as Dr Inge Konik are hard at work mapping these issues and seeking long-term solutions. Dr Konik,  a lecturer in the Department of Journalism, Media and Philosophy at the Nelson Mandela Metropolitan University (NMMU) shared her views in a presentation on 6 May 2016. She spoke about revaluing indigenous ways of life and subsistence-focused lifeways, linking this to materialist ecological feminism, or ecofeminism for short.

Dr. Konik’s presentation, hosted by the Department of Philosophy at the Bloemfontein Campus of the University of the Free State (UFS), was entitled: “Transversal reflections on ecological feminism and ubuntu.” The research underpinning the presentation derived from Dr Konik’s doctoral thesis which was supervised by Ariel Salleh (University of Sydney) and Andrea Hurst (NMMU).

Dr Konik’s research suggests that ecofeminism - which is a convergence between environmentalism and feminism - may hold the answers to the question of how we may work against environmental and social injustices. She also proposed that society look back toward subsistence communities of the past, and those currently being marginalized in our industrial societies, and linked the values evidenced in the practices of these communities to the African philosophty of ubuntu. In order to solve  complex contemporary challenges Dr Konik suggests that we combine these seemingly disparate theoretical frames - ubuntu and ecofeminism - by applying a transversal approach, which involves openness to dialogue  between traditions.

“My focus was on ecological feminism and critical theory and very specifically on South Africa, given the challeges South Africa faces - the environmental and social challenges and what kind of frameworks would be helpful,” said Dr Konik, who will officially become a postdoctoral research fellow at the department as of July 2016.

Prof Pieter Duvenage, Head of the Departement, stated that compelling research outputs are anticipated from Dr Konik as a fellow.
