    From Coal to Renewable Energy: Perspectives on South Africa's Energy Transition for a Sustainable Future.
    (University of the Witwatersrand, Johannesburg, 2024) Sebele, Temperance; Simatele, Mulala Danny
    South Africa has been experiencing an unstable electricity supply for years, leading to periods of load shedding from 2007 up to the present date. The electricity shortages have been attributed to distinct reasons, ranging from inefficient coal supply, skills shortages, sabotage by employees and lack of maintenance for nearly sixteen years. In addition to the electricity supply shortages, coal-fired electricity generation is responsible for roughly 80 per cent of South Africa’s total greenhouse gas emissions due to fossil fuel dependence, leading to many health, climate, and environmental challenges. To address the challenges related to fossil fuel dependency, moving to Renewable Energy sources that are climate and environmentally friendly is a necessity. The aim of this study was to investigate the optimal approaches that South Africa can embark on for a successful transition from coal to renewables. The institutional, policy, and strategic frameworks that exist within which South Africa can embark on for a successful transition were explored. Furthermore, the study sought to identify the challenges, and opportunities that exist or hinder the transition in South Africa. Lastly, the study explored how developments in the international policy frameworks influence South Africa’s ambitions to transition to renewables. The study is best suited to the pragmatism approach, and data were collected through the reviewing of literature, key-informant interviews, and questionnaires. A mixed-methods strategy that involved gathering both qualitative and quantitative data was employed and primary and secondary sources of data were used. The primary data sources used included key informants from various private and public institutions with an interest in South Africa’s energy matters such as ESKOM, SANEDI, SANEA, SAREC, SAPVIA, SAWEA, SAIPPA and NECSA. The non-probability sampling method was used in the participants’ selection from the sampled study institutions, with a combination of judgmental, snowballing and convenience sampling procedures employed at distinct phases of the research. Data collected was analysed both quantitatively and qualitatively, with interviews text data transcribed and analysed through manual tabulation and thematic analysis, and presented in graphs generated from Microsoft Excel, and the data from questionnaires analysed through the IBM Statistical Package for the Social Sciences (SPSS) software. The study revealed that the government played mainly four leading roles in the energy transition, which were providing financial support, legislative direction, institutional direction, and project oversight. Financial support is provided through financing projects and setting up financing policies that promote renewable energy investment, and legislative direction is provided through policy development and ensuring efficient implementation. Providing institutional direction is ensured through ensuring coordination across all spheres of government and capacitating institutions involved in the transition, and project oversight is provided through setting out renewable energy capacity determinations. The study further identified key energy transition elements, namely infrastructure, governance, legislation, stakeholders’ perceptions, and skills and strategies for a successful transition, which included channelling adequate financial resources to the renewable energy sector, privatisation of the electricity utility, diversification, rolling out bid windows, improving the legislative framework, improving grid access and integration, skills development, localisation of RE components manufacturing, providing incentives, and increasing consumer awareness about renewables. Several barriers to the transition were also identified, which included political interference and corruption, lack of financial investment, policies/legislation inadequacy, inconsistency in rolling out bidding windows, ESKOM’s monopoly, high cost of renewables, deficiency of incentives, skills and technology, labour unions, and deficiency of awareness on alternatives. The study recommends multisector reskilling of employees, since not all employees in the coal value chain may be interested in or able to be absorbed in the Renewable Energy sector. Furthermore, the government should fund and support progressive technologies and business models, improve the quality of institutions through merit-based appointments and uprooting corruption, privatisation of ESKOM to create opportunities for new entrants in the electricity market and improve stakeholder engagement and community support programmes. The UNFCCC must develop and ensure the implementation of enforcement strategies for holding countries accountable for their climate commitments for the transition to be realised

    The Role of Climate Change Governance in Community Adaptation in Kwazulu-Natal: A Study of uMkhanyakude District Municipality
    (University of the Witwatersrand, Johannesburg, 2024) Sibiya, Nomfundo Patricia; Simatele, Mulala Danny
    It can be argued that, although South Africa has developed good climate change initiatives, policies, and strategies, the implementation of these policies seems to present difficulties, as those for whom they have been developed do not seem to have any knowledge of their effectiveness in helping them build resilience against extreme weather events. Additionally, the findings demonstrate the existence of structures tasked with coordinating climate change matters across all government sectors affected, comprising inter-departmental arrangements, departmental arrangements, other institutions, and stakeholders. The inter-departmental arrangements consist of forums whose purpose is to ensure inter-sectoral coordination of climate change matters. The national Department of Forestry, Fisheries and the Environment assumes leadership and coordination responsibilities in developing and implementing responses to climate change adaptation in South Africa. The findings also revealed that government officials employed at the Department of Forestry, Fisheries and the Environment unanimously believe that the institutional arrangement of climate change at the national level effectively drives the climate change agenda. Conversely, government officials at the provincial and local levels exhibit diverse perspectives regarding the effectiveness of the institutional arrangements. Consequently, one can posit that there is inadequate coordination of climate change adaptation horizontally among national government departments and sectors affected by climate change impacts, as well as vertically between national, provincial, and municipal governments. This study divulged various barriers to climate change adaptation in South Africa, including insufficient financial resources, inadequate human capacity at provincial and local levels, limited political resolve at the local level, deficient comprehension of climate change adaptation issues among communities, insufficient coordination across government levels and sectors, absence of legal mandate at the local level, absence of climate change units at the district and local levels, lack of knowledge among certain staff members entrusted with environmental responsibilities at the local level, inadequate climate change plans in place at the local level, and utilisation of outdated climate change information in the Integrated Development Plans (IDPs). This study proposes that policies should be jointly designed and implemented with vulnerable groups, based on local knowledge, and tailored to the specific needs of those most affected by climate change (e.g., women, the impoverished). There is a necessity to establish operational institutions that are dedicated to fulfilling their mandate, supporting communities, and fostering robust partnerships among civil society, the public sector, and the private secto
