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.

Leeds academic presents a seminar on racism in the UK

A prominent researcher and academic, Dr Shirley Tate, recently delivered an academic paper – soon to be published – on racism at institutions of higher learning in the United Kingdom. The seminar was hosted at the Bloemfontein and Qwaqwa Campus by the Institute for Reconciliation and Social Justice.

Dr Tate spoke about colour-blind racism – where racism at an interpersonal level, racial differences and ethnic particularities are overlooked. Colour-blind racism continues to negate the fact that skin colour has consequences in societies where it has been claimed that 'race' no longer matters.

Dr Tate, author of two books, is particularly interested in exploring the intersections of 'raced' and gendered bodies, race performativity, critical mixed race and racism in organisations.

Her talk sparked a lot of interest from both students and staff who were extremely keen to find out more about her extensive research and its striking similarities to our South African experience.

Dr Tate is an Associate Professor in Race and Culture and Director of the Centre for Ethnicity and Racism Studies at the University of Leeds in the United Kingdom.
