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.

Freedom of religion is enshrined in the South African Constitution, states that everyone has the right to freedom of religion, which more specifically entails the freedom of conscience, religion, thought, belief and opinion. It makes provision for the protection of religious communities in South Africa. Consequently, the maintenance and protection of such a right is of fundamental importance.

Prof Shaun de Freitas, Associate Professor of Law at the University of the Free State (UFS) specialises in constitutional law, with a specific focus on the right to freedom of religion, and has produced several publications in the field. The latest is titled “Transcending the Private-Public School Divide in the Context of the Right to Freedom of Religion in South Africa”, Chapter 19, in Religious Freedom and Religious Pluralism in Africa – Prospects and Limitations published by Stellenbosch University in 2016.

Prejudice a challenge in all societies
There are numerous challenges faced by religious groups around the world concerning prejudice, association with terrorism and political power and influence. Therefore, research in this field becomes important in helping to uphold the rights and freedoms of religious minority groups, to be able to foster understanding between communities.

Balancing responsibility and religious rights
His current focus is on challenges that have arisen in South Africa, more specifically pertaining to the right of medical practitioners to object conscientiously towards participating in certain medical procedures, the parameters of freedom related to religious associations and the inclusion of religious expression in public schools. These matters are also relevant to many other parts of the world (including, ironically enough, those democratic societies that endeavour to make diversity flourish).
