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.

First-year wellbeing a top priority at Harmony residence

A unique residence that focuses on first-years’ experience, is exactly what Harmony sets out to provide for all first-year students at the University of the Free State.

A residence focusing on mentoring

Entering the adult world can be a daunting experience, but Harmony, unlike other residences on campus, focuses on mentoring. Harmony came to life in 2014 and has assisted many first-years in adapting to the university environment.

According to Pulane Malefane, Residence Head of House Harmony, they have witnessed a significant change in the pass rate of first-year students. “We have realised that first-years gain confidence much quicker than in other residences where they still need to find their way around seniors,” she says.

Adapting to the varsity environment

Harmony makes use of a Residence Assistants (RA) system, not Residence Committees (RC). The RA stay in corridors with their mentees in order to have close contact with them. An RA’s primary role is to be a mentor to first-years and also expose them to different co-curriculum activities on campus. They assist them in adapting to the varsity environment quicker, so as to be able to focus and concentrate on their academics.

Nicole Rabe, RA First-years, says the Harmony belles never cease to amaze her. “Watching these first-years grow from the high school girls that arrived at the start of this year, to the independent women they are now, has truly been a blessing.”

Malefane mentions that they intentionally try to place students from one faculty in the same corridor. In that way, mentors and residence assistants are in close proximity to them. “We have study rooms in each and every corridor of Harmony, making it easy for students to study close to their rooms at any time,” she says.

Phathutshodzo Nekhavanmbe, a first-year LLB student, says she could not have asked for a better house to be placed in. “The Harmony experience has been great so far, as the people living there are approachable and eager to lend a helping hand.”
