Could wave power be an answer to SAs electricity crisis
Attending a recent guest lecture, were from the left: Prof Marian Tredoux UFS Department of Geology, Prof Stoffel Fourie fromWalter Sisulu University, and Thoriso Lekoetje a third-year UFS Geology student.

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.

Each year the Mail and Guardian produces a special report on that year’s top 200 young South Africans who inspire, have talent, and drive. This year, we celebrate one of our own, Adv Loyiso Makapela, who has been nominated as one of the top 200 Mail and Guardian Young Achievers of 2016 under the category of Education. Loyiso is an outstanding academic, lecturer and mentor. At age 27, she is the youngest lecturer in the Faculty of Law.

With two Master’s degrees under her belt, she has been awarded the Desmond Tutu Doctoral scholarship by the National Research Foundation and will commence her PhD at both the University of Stellenbosch and Vrije Universiteit in Amsterdam July 2016. With a keen focus on research, she has presented papers and chaired sessions at various conferences locally and internationally in, for example, the United Arab Emirates and Greece, and in Oxford, England.

“The fact that I was nominated under the category ‘Education’ is undoubtedly one of my proudest achievements to date, because there is nothing I am more passionate about and love than the education of young South Africans, particularly women. This is only the beginning, and I hope my story and accomplishments will inspire others to walk out in determined pursuit of their goals and dreams,” said Loyiso.
She is in the final stages of launching a lifestyle website that aims to engage young and ambitious South African women, titled “Young Women of Power”. Through this platform, Loyiso hopes to bring together influential women in business and politics, to empower and enlighten younger women.

The Mail and Guardian Top 200 Young South Africans have, over the years, positioned themselves as leaders in their fields and gained local and international acclaim. The selected 200 will be announced later this month.
