Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050.

Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050. The energy mix by 2050 is focused on renewables and the long-term journey is very clear: we have to be renewable driven.

This is according to panellists speaking at the University of the Free State’s (UFS) third webinar in the 2022 Thought-Leader webinar series. The webinar titled, What needs to be done to POWER up South Africa? comprised panellists Matthew Mflathelwa, General Manager: Strategy and Planning at Eskom; Steve Nicholls, Head of Mitigation at South Africa’s Presidential Climate Commission (PCC); Happy Khambule, Environment and Energy Manager at Business Unity South Africa (BUSA); and Louis Lagrange, Head: Department of Engineering Sciences in the Faculty of Natural and Agricultural Sciences, UFS. 

We need to invest in new infrastructure

In his presentation, Mflathelwa talked about how Eskom can unlock additional grid capacity and how to start rolling out business models to enable this transition. 

“On the demand side, we are looking at some exciting and interesting initiatives. We are looking at how we can start to aggregate or leverage the idea of consumers becoming prosumers, and leverage technology to aggregate the potential supply and management demand from that perspective.” 

“The question is also how to do this sustainably in the long term. We need to invest a considerable amount of new infrastructure,” said Mflathelwa. 

According to him, it is not a secret that most of Eskom’s generating assets are approaching the end of life. The question now is how to proactively plan for this to ensure that we address the problem of load shedding sustainably. “The big takeaway is that there is a significant amount of new capacity that needs to be built and this is predominantly going to be renewables, but it is not the only additional infrastructure that is required. We need an energy mix that can respond and achieve adequacy for the future requirements.”  

Another important element that is often neglected is the transmission of grid infrastructure, given the penetration or entry of new players with greater penetration of renewable energy and the advantages that come with distributing these energy sources across the country. There is a lot of transmission and distribution infrastructure needed to enable this future capacity.

Some of the things also being discussed, said Mflathelwa, are how to enable greater and faster penetration of new capacity – specifically renewables to aid in the reduction of environmental challenges.

The next decade is critical 

Nicholls gave a climate-friendly perspective on the work that Eskom is doing, saying energy transition in SA is core to the overall economy transition and getting a zero-carbon, least-cost energy system is fundamental to the strategy of the country. 

“We need to move from carbon emissions of around 480 megatons per annum today to somewhere between 350 and 420 by 2030, and then onto zero carbon emissions by 2050. If South Africa is to reach net-zero by 2050, we need targeted investment between now and 2030, setting the stage for accelerated investment in decarbonisation post 2030. The next decade is critical. Given the state of South Africa’s balance sheets, international support and foreign direct investment are critical.”

Nicholls said the energy mix by 2050 is really focused on renewables, and the long-term journey is very clear: we have to be renewable driven. The short- and long-term solutions are alike; renewables are cheaper, quicker to get onto the grid, pending some investment in the grid.   

“In the long term, we need big investments in renewables – about 6 GW a year between now and mid-2050. We need a big investment in the transmission grid. Hydrogen plays a critical role in decarbonisation of power and industry. Energy efficiency is key. It’s really the unsung hero in this conversation. If we can be energy efficient, we can take two power stations off the grid and that makes a big difference in terms of affordability.” 

“Transport is also important; if we are going to be a net-zero economy, we have to fully electrify the transport fleet, which puts an extra load on what Eskom needs to achieve,” Nicholls said. 

Energy efficiency is most critical

Khambule emphasized that the country needs to focus on using energy in an efficient manner in the commercial and household sectors, as energy efficiency is critical to the country’s power supply issues in the short term. According to Khambule, the country is not using energy in an efficient manner.

"If we are able to use power the minute it is necessary and become more efficient with it, we can get more value out of that power," said Khambule.

Lagrange concurred with Khambule on the importance of energy efficiency, referring to it as ‘the unsung hero’. “Energy efficiency is the biggest solution that we can have, and people need to be trained on how to use energy efficiently,” said Lagrange.

Khambule also addressed the issue of power cuts, saying the unpredictability thereof, even in the short-term, further exacerbated the situation.

"The unpredictability of load shedding has become much more of a driver for uncertainty, which leads to a lack of business confidence, and secondly leads to losses in production;  a key notion is that if we have predictability of load shedding, planning can be undertaken, and if planning is undertaken in a more judicious manner, then we are at least able to keep the losses at a minimum and see how we can weather the storm until a sustainable supply can be implemented."

Khambule also added that in the short and mid-term, solutions must consider protecting or mitigating options for vulnerable sectors. “In some industries – such as health care, power is essential and there is a need for predictable supply. Therefore, some sectors will require mitigating solutions to protect some essential sectors,” said Khambule.
According to Lagrange, no amazing technology for the generation and distribution of energy has been developed over the past decade. “We need to reimagine the entire current regulatory systems business model, because it is caught up in an energy stagnation, which is frighteningly fragile from a physical and cyber-security point of view,” added Lagrange.

Historians must place African history on world stage – Dr Zeleza

“African historians must take seriously the challenge of placing African history in world history, and in the history of our species, Homo sapiens.”

With these words, Dr Paul Tiyambe Zeleza, Vice Chancellor of the United States International University-Africa in Nairobi, Kenya, stressed the continent’s challenge.

According to him the contest should continue to recover and reconstruct Africa’s long history. Liberating African knowledges can be done by: “Provincialising Europe that has monopolised universality, universalising Africa beyond its Eurocentric provincialisation, and engaging histories of other continents on their own terms.”

University celebrates Africa Month in various ways  
Dr Zeleza delivered the ninth Africa Day Memorial Lecture, titled The Decolonisation of African Knowledges, at the University of the Free State (UFS). The lecture, hosted by the Centre for Africa Studies (CAS), took place on 24 May 2017 in the Equitas Auditorium on the Bloemfontein Campus and was one of the ways in which the UFS celebrated Africa Month.

Scholars should immerse themselves in these thoughts

Dr Zeleza focused on two issues, which he said were interconnected. They were the unfinished project of decolonising African knowledges and the continent's positioning in global knowledge production.

He said Africa’s scholars and students should “immerse themselves in the rich traditions of African social thought going back millennia”. According to him the continent’s research profile still remains weak in global terms.

“It is imperative that the various key stakeholders in African higher education from governments to the general public to parents, and to students, faculty, staff, and administrators in the academic institutions themselves, raise the value proposition of African higher education for 21st century African societies, economies, and polities.”

“Colonialism is associated with injustice
and inequality, but what happens when
our liberators become our oppressors?”

Library celebrates with panel discussion and book launch
The UFS Sasol Library celebrated Africa Day by presenting a book launch and panel discussion on 25 May 2017, on the pertinent and current political theme of land redistribution with a comparative basis of land invasions in Zimbabwe.

Prof Irikidzayi Manase discussed his book White Narratives: The Depiction of Post-2000 Land Invasions in Zimbabwe, accompanied by Rev Henry Jackson who wrote Another Farm in Africa. A perspective of the economic implications of land redistribution in South Africa was discussed by panellist Arno Van Niekerk: Senior Lecturer of Economics at the UFS Faculty of Economic and Management Sciences.

Inequality still an African problem
The content of the books are a stark reminder of the burning issues of inequality and loss of identity of those who lost their farms in Zimbabwe, a collection of memoirs by white farmers and their families. Rev Jackson gave a religious perspective on reconciliation, forgiveness and the question of land ownership, saying that healing of injustice begins with forgiveness of past transgressions.

Van Niekerk highlighted that while land issues were important, “social cohesion is affected by the economic decisions that will be made”. In closing, Prof Manase called for serious consideration of what the future may hold. “Colonialism is associated with injustice and inequality, but what happens when our liberators become our oppressors?” 

The panel discussion was attended by staff and students of the university, and was lit up by robust discussions on possible historical and future solutions to the question of land, decolonisation and political power struggles in Southern Africa and lessons to be learned from Zimbabwe.
