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.

UFS attracts excellent and diverse students

When Thato Monkoe and Matshediso Mokoena sat for their final matric examinations in 2014, all they had on their minds was not just passing, but passing well. Little did they know at that time that passing well would place so much responsibility on their shoulders.

 

Both Thato and Matshediso come from rural and disadvantaged backgrounds. They are first-year students at the Qwaqwa Campus of the University of the Free State, and are the first in their respective families to study at a university.

 

Thato describes his situation as “sad and good at the same time”.

 

“It is good, because I am the first one at home to have completed my matric and to have gone on to study at a tertiary institution. At the same time, it is sad as I feel sorry for my siblings who, for various reasons, did not have similar opportunities when they opted out of school”, said Thato, a BEd student.

 

”Now my sister and brother, as well as the entire family, perceive me as the one with brains, and this makes me uncomfortable. However, I am up for the challenge to be the first one to graduate with a degree in my family”.

 

Matshediso Mokoena, a BSc student, who obtained distinctions in Mathematics, Physical Sciences, and Life Sciences last year, concurs with Thato.

 

”As much as my family is supportive, there is always pressure as they expect the best from me,” she said.

 

“The pressure does not only come from my family. My entire community looks up to me, and they can’t stop talking about my achievements”, Matshediso revealed.

 

Both Thato and Matshediso are, however, happy that the dark cloud of doubt about academic achievement in their families has finally disappeared.

 

“At least someone in my family is hard at work carving her future, and willing to set a good example. That person is me”, said Matshediso, who aspires to be a medical doctor, and has a younger sister in Grade 8.

 

Thato and Matshediso are just two of hundreds of students making good use of the University of the Free State’s commitment to attract excellent and diverse students at both undergraduate and postgraduate levels, as reflected in the Strategic Plan 2015-2020.
