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.

Now is the right time to talk, says Njabulo

Studying at a multicultural campus adds a lot of colour and spice towards every student’s experience, and it also offers some necessary challenges.

This belief is held by the Qwaqwa Campus SRC member responsible for RAG, Community Service & Dialogue, Njabulo Mabaso.

“Our multi-culturalism should be our uniting force, especially at this time in our country. What started as a one-person protest against the Cecil Rhodes statue at UCT should be used to broaden our view in relation to challenges that we are still facing as students and as a country. We need to talk more”, said Mabaso, a final-year BEd FET Languages student.

“Now is the right time for us to really talk about issues affecting us as young adults. Matters of collective interest like pregnancy rates, alcohol and substance abuse, sexism, crime, xenophobia, etc. need to be tackled”, added Mabaso, a weightlifting fanatic.

“As the student leadership, we intend working closely with community structures as we come from the very same communities. We must not wait for Mandela Day to do good.”

“My portfolio, together with Arts and Culture and Sports Affairs portfolios, can create that necessary social cohesion that we as students and our communities need so much.”

Mabaso said that all perceived taboos should be dealt with.

“Our programme this year encourages open dialogue. Nothing should still be treated as a ‘no-go area’ if we are to survive the scourge of HIV. We must talk openly, despite the cultural challenges that might restrict us. We must talk about homophobia. We must talk about rape. In fact, how many students – male and female – really understand what rape is? Does culture even recognise the ‘no’ factor associated with rape? It is important that we should not leave it until it is too late. We must not wait until it is his word against hers. We must deal with these matters now. The right time to engage is now”, he added.
