Could wave power be an answer to SAs electricity crisis
Attending a recent guest lecture, were from the left: Prof Marian Tredoux UFS Department of Geology, Prof Stoffel Fourie fromWalter Sisulu University, and Thoriso Lekoetje a third-year UFS Geology student.
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.

Prof. André Keet, Director of the Institute for Reconciliation and Social Justice at the university, has been appointed as member of the Oversight Committee on the Transformation of South African Universities. He is one of seven committee members that were appointed by the Ministry of Higher Education and Training to monitor progress on transformation in public universities.

The committee will advise Dr Blade Nzimande, Minister of Higher Education and Training, on policy to combat racism, sexism and other forms of unfair discrimination in public higher education. The committee will also advise on the role of universities in promoting the development of a free, fair and non-discriminatory society beyond the world of the academia.

The senior leadership of the university has welcomed the appointment of Prof. Keet and said with his extensive experience as a former Commissioner on the Commission for Gender Equality and as the Director of the university's Institute for Reconciliation and Social Justice (which was formed as one of several initiatives taken by the senior leadership in the aftermath of the Reitz incident), Prof. Keet will be a valuable member of the committee.

"Prof. Keet has the experience and expertise to guard the autonomy and academic freedom of universities, thus avoiding this committee from becoming a political intervention in the affairs of the higher education sector," said Prof. Jonathan Jansen, Vice-Chancellor and Rector of the university.

Honoured to be elected on the committee, Prof. Keet said he is ready to serve the national interest in the transformation of South African universities. "The appointment is also a compliment to the university and to its exceptional experience in the process of transformation."

Prof. Keet will serve on the committee for a period of three years. The other members of the committee are Prof. Malegapuru Makgoba, who will serve as chairperson, Dr Mvuyo Tom, Ms Nazeema Mohamed, Ms Zingiswa Losi, Mr Joe Mpisi and Prof. Shirley Walters.
