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.

The most talented students of the Bloemfontein Campus have been announced. 

Johann Steyn, a final-year LLB student and SRC member, was named as the SRC Dux Student for 2013. He and seven other students were recognised for their academic achievement and participation in extracurricular activities. 

Jean Vermaas, also a final-year LLB student, and Onthathile Serehete, a fifth-year medical student, were announced first and second runner-up respectively. 

In a new category introduced this year, Jomari de Beer, Mpho Sefo, Lehlohonolo Mofokeng, Richard Chemaly and Foster Lubbe received student achiever awards based on exceptional achievement, representing the university in renowned organisations or structures. 

The SRC Dux Student Award is granted to a final-year undergraduate student who has demonstrated excellence in academic achievement, co-curricular and community involvement, and student leadership.
