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.

Make the right choices and you will succeed, Prof Jansen advises learners
2014-05-30

“You can make a choice today that will end up with you being pregnant, having babies, being unemployed, sitting at home like some of our brothers and sisters, uncles and aunts. Or you can make a different decision – and that decision is about you working so hard that you earn entry into the University of the Free State, get your degree and become great, not only in South Africa, but in the world.”

This was the message from the UFS’s Vice-Chancellor and Rector, Prof Jonathan Jansen, who addressed prospective Kovsies during our Open Day on the Qwaqwa Campus on Saturday 24 May 2014. Prof Jansen advised all learners to always make the right decisions.

“The first right decision is to pass well. You must go for 60%, 70% and 80% passes. Set yourself a target and do not just strive to pass, but to pass well,” Prof Jansen told a packed Rolihlahla Mandela Multi-purpose Hall, with learners coming from as far as Ficksburg, Lindley and Koppies.

“The second thing that you need to do, is to believe in yourself. Do not believe people who tell you what you can or cannot do. Believe in what you can do,” said Prof Jansen.

“Thirdly, you have to get up and do things for yourself. You have to work hard, sleep less and study hard. Don't accept excuses. If you can do these three things, then the best place to study is the University of the Free State. Believe that the sky is the limit.”

“We learned a very valuable lesson here today,” said Tumelo Mofokeng from Nkarabeng Secondary School in Kestell.

The fun-filled programme included performances and messages of encouragement from current students who have been part of the unique Leadership for Change Programme. This programme equips first-year students with skills to reflect, dialogue and engage on issues of diversity and leadership.
