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.

On Thursday 11 December 2014, the university awarded a total of 392 qualifications during our Summer Graduation Ceremony in the Callie Human Centre on the Bloemfontein Campus. Of these, 225 were awarded to graduates from the Faculty of Health Sciences, while 134 master’s degrees and 33 PhDs were awarded in the other six faculties. Another 74 diplomas and 56 certificates were also awarded in the School for Open Learning.

Well-known radio personality, Redi Thlabi, and acclaimed cardiothoracic surgeon, Dr Susan Vosloo, encouraged and inspired the graduates during the two ceremonies on the day.

During the morning session, Thlabi imparted some of the valuable lessons she learned in her personal life as well as in her career. She encouraged graduates to change the script of our country for future generations, to be mindful of others and to find meaning in whatever you do.

“Those who have a platform, a voice and an education have the power to help others further on their journey,” Thlabi said. “I believe we are living in an exciting time – a time to leave a legacy behind, a time to make a mark in this world.”

Graduates from the Faculty of Health Sciences and the School for Open Learning were addressed by Dr Vosloo during the second ceremony.

Dr Vosloo often referred to the success of transformation at our university and added that few successes are achieved without adversity. She encouraged the afternoon’s graduates to become professionals with a high sense of dignity, accountability and transparency in their workplace.

“Remember that you and you alone are able to decide what your approach will be in anything in life from here on forward,” she said.

Dr Vosloo, a Kovsie alumnus, graduated in 1980. Shortly after this, she became the first female heart surgeon in South Africa. She is currently in independent private practice at Christiaan Barnard Memorial Hospital, having also worked from 1998 untill 2012 at the Vincent Pallotti Hospital in Cape Town.
