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.

University gets support to improve student success

The Kresge Foundation has awarded $400 000 (about R4 million) to the University of the Free State (UFS) to increase student success through improved data analysis.

This four-year grant, as part of Kresge’s Siyaphumelela initiative, was recently announced by Mr Rip Rapson, Kresge’s President and Chief Executive Officer. This announcement was made at a symposium on South African higher education and philanthropy in Cape Town.

“Universities across South Africa are grappling with how to improve persistence and graduation rates for their black students in particular,” Mr Rapson said. “These universities will work together with the South African Institute for Distance Education to develop their data analytics capacity to find and share solutions and interventions based on solid information to improve student success.”

The UFS was only one of four universities receiving funding from Kresge. The other universities include the Nelson Mandela metropolitan University in Port Elizabeth, the University of the Witwatersrand in Johannesburg and the University of Pretoria.

The grants will help the universities build their capacities to use data to better integrate institutional research, information communication technology, academic development, student services and academic departments. Beyond the improvements sought for the UFS, Kresge hopes to see new approaches to data become mainstream for higher education in South Africa.

The Siyaphumelela initiative provides four years of institutional support and hope to create a community of practice that learns lessons that may benefit not only individual institutions and the cohort, but also potentially all of South African higher education.

Dr Lis Lange, Vice-Rector: Academic at the UFS, said improving student successes is a university goal that operates in the interface between the Human and Academic Projects of the university.

“We are delighted to be part of an initiative that is going to help us develop greater capability for data analytics and deeper integration between data and teaching and learning practices; and, at the same time, will bring the Centre for Teaching and Learning, the Directorate for Institutional Research and Academic Planning (DIRAP) and the faculties into a closer cooperation.”

Over the past four years donor income to the UFS increased considerably, both from governmental sources, trusts and foundations. By the end of 2013, governmental funding increased from about R5 million in 2011 to over R35 million. Funding by trusts and foundations increased from R5 million in 2011 to over R15 million in 2013. A general increase of 25% in funding is expected for 2014.

Dr Marcus Ingram, UFS Director for Institutional Advancement, says as the UFS begins to settle into a refined academic identity, the Department for Institutional Advancement intends to support these efforts by helping to facilitate the telling of a more integrated narrative to the university’s friends, prospects and donors.
