Dr Jacques Maritz, Albert van Eck, and Dr Nola Redelinghuys are among the University of the Free State researchers driving an interdisciplinary project that combines social insight, high-performance computing, and ecological engineering to support South Africa’s just energy transition.

The University of the Free State (UFS) is taking bold steps to address the complexities of South Africa’s energy transition by combining expertise across disciplines, innovative technologies such as high-performance computing (HPC), and active student involvement. This forward-thinking approach is positioning the UFS at the forefront of solving real-world challenges linked to renewable energy adoption and social dynamics, while equipping students with future-ready skills.

 

Interdisciplinary solutions for a just energy transition

“Current grand challenges – the pressing societal and scientific problems shaping research at the UFS and globally – require students and researchers to include computational approaches such as modelling, simulations, and large-scale data analysis,” says Dr Jacques Maritz, Head of the Unit for Engineering Sciences at the UFS.

“One such example is in merging social dynamics with energy paradigms – two seemingly different worlds, yet connected via scientific elegance,” says Dr Maritz. Energy decisions, such as shifting to renewables, are shaped by the behaviour of communities, governments, and industries. As a recent response to these challenges, ecological and nature-based engineering sciences at the UFS aim to integrate human activity into nature, while benefiting both via the merging of computation, ecological engineering sciences, nature-based solutions, and data-driven complexity science. 

The UFS’ pioneering project models these complex social-energy relationships to better understand how South Africa can sustainably and justly transition from fossil fuels to renewable energy. This interdisciplinary effort involves researchers and students from physics, sociology, engineering, data science, and mathematical modelling working together to map these interdependencies shaped by economic, political, cultural, and community forces.

For students such as Lurgasho Minnie, a final-year MSc Astrophysics student, this interdisciplinary exposure is transformative. “It has given me a new lens or perspective on approaching and solving problems in my field of research. By approaching challenges from an interdisciplinary point of view, new methods and techniques can be applied to solve challenging problems,” he says.

A crucial part of this research involves modelling dynamic social-energy networks using systems thinking, network analysis, and scenario planning. These tools help simulate interactions between government policies, community behaviour, environmental impacts, and technological innovations, allowing researchers to predict and plan for different future scenarios.

Students are actively shaping this work. The first set of social data was collected by UFS students on the Qwaqwa Campus, with training and support from the Centre for Global Change and Student Affairs. These data-gathering efforts are not only enriching the research but also building students' skills in real-world data collection and analysis.

“One of the study objectives is to inform the development of an awareness campaign about the complexities inherent in transitioning from a predominantly non-renewable to a renewable energy system, firstly aimed at UFS students but ultimately at the broader community,” explains Dr Nola Redelinghuys, Senior Lecturer in Sociology at the UFS.

The research team also hopes to help shape sustainable energy solutions for the university itself, with plans to create a renewable energy supply network that balances energy demand and renewable supply across the UFS campuses.

 

High-performance computing powering new insights 

At the heart of this initiative is the UFS High-Performance Computing (HPC) Unit, which enables researchers to run complex simulations and process vast data sets. The HPC is essential for solving problems that require immense computing power and data storage, and the UFS is making these resources accessible to a growing number of students – even those from non-computational disciplines.

“The eResearch and HPC team promotes the development of new skills and knowledge to harness the power of HPC and expand one’s technological abilities to solve problems. The HPC staff must first train a student or researcher to use the system effectively before using their toolsets. Thereafter, students can streamline or even automate specific processes by using a collection of more generic toolsets. Even if not using an HPC daily (or after entering the workforce), the HPC methodologies and toolsets they are exposed to often change how a person approaches future problem sets. Students using the HPC are more likely to share their experiences and are encouraged to assist other students in their department to lessen the burden of entry for newcomers. This broadens the collective knowledge within a department on their toolsets and how to use them effectively,” says Albert van Eck, Director of the UFS HPC.

Students can also learn how to build and configure basic HPC clusters through freely available training materials, opening doors to careers in private cloud hosting, data science, genomics, and other tech industries. By focusing on open-source tools, the UFS ensures that students acquire industry-relevant skills without being locked into specific software vendors.

The project is also laying the groundwork for partnerships with renewable energy companies, technology firms, NGOs, and development agencies. These collaborations will strengthen the UFS’ industry ties and create more work-integrated learning (WIL) opportunities for students.

As part of UFS Vision 130, this project advances academic excellence, societal impact, and inclusivity. By involving diverse staff and students from both the Bloemfontein and Qwaqwa Campuses, it demonstrates the university’s commitment to building a future-ready, skilled, and socially conscious graduate community prepared to tackle South Africa’s energy challenges.

In a country grappling with energy security and the need for a just transition, the UFS’ approach – blending social insight, cutting-edge technology, and student empowerment – offers a valuable model for addressing one of the nation’s most pressing development priorities.

Protection of Information bill- opinions from our experts
2011-11-28

Prof. Hussein Solomon
Senior Professor in the Department of Political Science at the University of the Free State. 

In recent years, given their failure to effectively govern, the ANC has become increasingly defensive. These defensive traits have become particularly acute in light of the various corruption scandals that members of the ruling party involve themselves in.
 
Given the fact that for now they are assured of an electoral majority (largely on account of their anti-apartheid credentials), coupled with the fact that they have managed to make parliament a rubber stamp of the executive as opposed to holding the executive accountable, it is the media which has increasingly held the ruling party to account by exposing such corruption and incompetence in government.
 
The passing of the information bill, therefore, is not merely an attack on the media, but an attack on the pivotal issue of accountability. Without accountability, there can be no democracy.
 
By defining national interest broadly, by refusing to accept a public interest clause in the bill, the ANC increasingly shows its disdain to South Africa's constitution and its citizens.
 
More importantly, as former Minister of Intelligence and ANC stalwart Ronnie Kasrils pointedly makes clear, the ANC is also betraying its own noble struggle against the odious apartheid regime. It was the media which played a key role in exposing apartheid's excesses, it is the same media which is coming under attack by the heirs of PW Botha's State Security Council - Minister of State Security Siyabong Cwele and his security apparatchiks whose mindsets reflect more Stalin's Gulag's than the values of the Freedom Charter.
 
The passing of this bill is also taking place at a time when journalists have had their phones attacked, where the judiciary has been deliberately undermined and parliament silenced.
 
Democrats beware!

 
Prof. Johann de Wet
Chairperson: Department of Communication Science 
 
The ANC’s insistence on passing the Protection of State Information Bill in its current form and enforcing it by law, means that the essence of our democratic state and the quality of life of every citizen is at stake.
 
Yes, our freedom as academics, researchers, mass media practitioners and citizens comes into play. Freedom implies the right to choose and is, along with equality, an underlying principle which helps make democracy happen. While the South African state needs to protect (classify) information which could threaten its security and/or survival, the omission of a public interest clause in the Bill at this stage effectively denies a citizen the right to freedom of information.
 
 Freedom of information, along with press freedom, freedom of speech, freedom of assembly, freedom of association and religious freedom, are essential to democracy. These freedoms are granted because they conform to basic liberal ideas associated with (Western) democracy and which resonate with South Africa’s liberal constitution, such as (1) belief in the supreme value of the individual (and thus not of the state); (2) belief that the individual has natural rights (rights which belong to all human beings by nature – such as the right to life and to control government)) which exist independently of government, and which ought to be protected by and against government; and (3) recognition of the supreme value of the individual. 
 
One wonders how many cases of South African government corruption and mismanagement would have been uncovered by investigative journalists over the past number of years if this Bill in its current form was on the statute books. This Bill represents a backward step from the promise of democracy of having an informed public. The former National Party government had similar laws in place and one does not want to go there again. The infamous Information Scandal in South Africa of some thirty years ago, or Muldergate as it has come to be known, reminds one of what governments can do when it works clandestinely.
 
What South Africans need, is more information on what government structures are doing and how they are doing it with taxpayers’ money, not less information. While information in itself does not equal communication or dialogue, it is an indispensable part thereof, and the need for dialogue based on verifiable information is urgent for meeting vexed challenges facing South African communities. Academics in all fields of specialisation are constantly in need of untainted information to pursue answers and/or offer solutions to where South Africa should be moving in all spheres of life.
