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.

They came from near and far. Some hail from Bloemfontein, others from as far away as Botswana but they all have one thing in common. They were here to start their first year as Kovsie students. Thousands of first-year students, along with parents and guardians, attended the first year welcoming on the Qwaqwa and Bloemfontein campuses on 18 and 19 January 2013 respectively.

“I do not care whether you come from the Free State or Zimbabwe or whether you are from Gauteng or Lesotho. I do not care if you speak Sesotho, Setswana or Afrikaans. What I care about is that you must understand that you are smarter than you think.”

This was the message from Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), when he officially welcomed first year students to the Qwaqwa Campus. “At the UFS, we put emphasis on two very important projects - the academic and human projects”, said Prof Jansen.

“The academic project is about you excelling academically as a student. It is about being the best you can be in your chosen field of study. All of you should strive to be like Zandile, a young girl from Umlazi who, despite her poverty and challenging conditions at home, went on to attain seven distinctions in her 2012 matric results”, said Prof Jansen. He was referring to Zandile who he tracked down via Facebook to offer her a full bursary to study at the UFS. Zandile had appeared on SABC TV news, expressing her frustration at the lack of funds to continue her studies, despite her performance.

“The human project is about you loving those who are different from you, thus becoming better human beings,” Prof Jansen said.

Prof. Jansen echoed the same message on the Bloemfontein Campus the following day when he welcomed thousands of new students. These students, their parents and guardians packed the huge tent that was erected in the CR Swart parking area of the campus. Prof. Jansen welcomed students from the different faculties during four sessions. He told parents and students that the class of 2013 was the smartest class the university had had in its 109-year history.

Mr Rudi Buys, Dean of Students, informed them about the many opportunities that awaited them at Kovsies. These include programmes like the Leadership for Change Programme for first year students and the Stanford Sophomore College Program for second year students.
