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.

The UFS continues to produce leaders and is proud to have three Mandela Rhodes scholars next year.

Lehlohonolo Mofokeng, Zola Valashiya and Tumelo Morobane all received this prestigious scholarship for 2015.

A Mandela Rhodes Scholarship provides full funding for a maximum of two years of postgraduate study. The award is open to all African citizens under the age of 30 years and recipients must study towards an honours or master’s degree at a recognised South African institution. Although there is no maximum number of awards, the scholarships are highly competitive, with fewer than 30 scholarships being awarded each year since its inception in 2005. The scholarships cover tuition, accommodation, meals, book allowance, general allowance, and travel expenses. Recipients of the Mandela Rhodes Scholarship are students with outstanding academic achievements, who also possess leadership ability, entrepreneurial skills, and a commitment to reconciliation. In addition to receiving funding for their studies, scholars also do a leadership development programme while in residence. The award is named after Nelson Mandela and Cecil Rhodes and is administered by the Mandela Rhodes Foundation, which is a partnership between the Nelson Mandela and the Rhodes Trusts.

Lehlohonolo has just finished his BEd Hons in Philosophy and Policy of Education at the UFS. He hopes to enroll for a master’s degree in Education Policy, Planning and Management at the University of Witwatersrand with his Mandela Rhodes Scholarship.

Zola is originally from Johannesburg and is completing his LLB degree at the UFS this year. He is planning to stay at the UFS in 2015 to do his LLM in Constitutional Law or International Human Rights Law.

Tumelo has a BSc Honours in Actuarial Science and will use this scholarship next year to study towards her master’s degree at the UFS.

“I chose to stay at the UFS because I am doing a great master's project with Munich Re through the UFS,” says Tumelo. 

“Furthermore, the CEO of the Mandela Foundation, Mr Sello Hatang, asked me to work with the foundation on a few projects that mostly focus on keeping the girl child in school across Africa, as well as helping with providing training and workshops on entrepreneurship to young people.

“So, I am looking forward to a very busy year ahead of me, which will be filled with so much learning, growth and making a difference,” Tumelo says.
