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.

Tough future if nothing changes in Africa
2015-02-20

 

The Department of Political Studies and Governance at the UFS recently hosted a workshop with the Osaka School for International Public Policy and the Southern African Centre for Collaboration in Peace and Security Studies.

The workshop, which was held on Thursday 12 February, had the theme of Perspectives on African Peace and Security. During workshop sessions, thoughts and views on peace and security were discussed for both African and South African circumstances. This was the fourth year of this joint workshop at the UFS.

Prof Hussein Solomon from the Department of Political Studies and Governance at the UFS shared some notes:

“In terms of South Africa, the fact that only 11% of South Africans have a post-school education holds negative prospects for us attaining a so-called ‘knowledge economy’”, says Prof Solomon.

“This also means that unemployment will continue to remain high since, in certain key areas, the South African economy is quite sophisticated, and needs a sophisticated labour force. Therefore, high unemployment translates into further social unrest, especially if one considers that youth unemployment is approaching 50%.”
 
Moving to broader issues in Africa, Solomon states that governance remains a challenge.

“There is a need to move away from Eurocentric forms of governance to more hybrid forms, implementing a mix of western forms of governance alongside more traditional forms.”

“Otherwise, the probability of conflict remains high as we look into the future. The possibility of water wars between African states is distinct.”

“Terrorism too will be with us for some time to come, with three terrorist attacks per day in Africa. Making matters worse, whether it is conflict over water or terrorist atrocities, is the African Union’s inability to resolve these issues. It simply does not have the capacity”, says Solomon.
