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.

Report card outlines major achievements
2005-02-04

Staff at the University of the Free State (UFS) have received above-inflation increases in remuneration averaging 18,2 percent since the year 2000, according to the Rector and Vice-Chancellor, Prof Frederick Fourie.

Delivering a keynote speech at the Official Opening of the UFS today, Prof Fourie gave a report card for the UFS which he said indicated significant progress in salaries and promotions as well as capital expenditure and infrastructure development on the campus.

“The aggregate extra earnings of staff (money in their pockets above inflation) from 2000 to 2005 amount to R75 million in salaries. This is the result of the hard work of all staff and we pay tribute to them,” he said.

Prof Fourie said that several categories of staff are better off than before the financial turn-around strategy was implemented in 2000 which aimed to make the UFS a financially sustainable campus.

The lowest paid workers and professors had received an additional structural correction, which gave professors at the UFS a 27% above-inflation increase (on total remuneration package) since 2000.

He said there had also been a dramatic increase in promotions to associate professor and full professor during the last 6 years.

From 1999 to December 2001, there were only 9 promotions to associate professor. From January 2002 to January 2005, there were 37 such promotions to associate professor, four times as many.

Regarding promotions to full professor, from 1999 to December 2001 there were 7 promotions. From January 2002 to January 2005, there were 31 promotions to full professor, more than four times as many.

“We have also created a new category of senior professor to give due recognition to the outstanding work of our leading academics in many fields,” Prof Fourie said.

The UFS has introduced numerous new and innovative learning programmes, together with an increasing number of community service modules which enhanced the UFS as a leader in service learning and helped to make it a university engaged with its surrounding community.

According to Prof Fourie the number of support staff had also grown along with the professionalisation of the support services.

He said management was aware that there still several challenges regarding staff overload and staff development but that these were being addressed
