Introduction
South Africa’s energy sector stands at a crossroads in 2025, characterized by heavy reliance on coal for electricity generation, which accounts for 81% of the mix, while low-carbon sources like solar (9%), wind (5%), and nuclear (3.5%) make up nearly 18% [1]. This dominance persists despite environmental concerns and international commitments to decarbonization, as highlighted in the OECD Economic Surveys: South Africa 2025, which notes insufficient progress in renewables to meet emission targets [2]. Recent improvements in Eskom’s coal fleet, with an energy availability factor (EAF) peaking at 70% in 2024, have reduced loadshedding, but total electricity demand fell 3% that year, reflecting economic strains and rising tariffs [3]. The Integrated Resource Plan (IRP 2023) projects coal capacity rising to 39.4 GW by 2030, even as renewable targets are scaled back to 25.7 GW [2]. Amid these dynamics, private sector distributed generation has surged, projected to reach 11.3 GW by 2030, offering a buffer against grid instability [2][3]. This overview sets the stage for examining coal’s grip, renewable growth, and the path forward.
Coal’s Enduring Dominance and Challenges
Coal remains the backbone of South Africa’s energy mix, powering major stations like Medupi and Kusile (each 4,800 MW), alongside Kendal, Majuba, and Lethabo [1][3]. In 2024, coal-generated energy increased due to better plant availability, yet the sector’s CO₂ emissions continue to dominate, exacerbating climate impacts [2][3]. The CSIR Utility Statistics Report for January 2025 reveals that while Eskom’s EAF improved from 59.92% in 2023, no new utility-scale capacity was added, underscoring reliance on existing infrastructure [3].
Expert analyses point to economic and political barriers sustaining this dominance. The OECD report criticizes the IRP 2023 for not planning coal plant closures, instead prioritizing completions like Kusile’s Unit 6 in September 2025, which boosted capacity but overran budgets significantly [2]. Social media reflects public frustration, with users highlighting coal’s cost-effectiveness per kWh versus renewables’ higher rates, often labeling the latter as inefficient despite investments. However, NGOs emphasize health costs in Mpumalanga, where pollution affects low-income communities, advocating for phased decommissioning.
Renewable Energy Growth and Technological Innovations
Renewable capacity is growing modestly, driven by the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP), which focuses on solar and wind in resource-rich areas like the Northern Cape [4]. By 2030, total renewables are projected at 25.7 GW, with distributed generation jumping from 4.5 GW to 11.3 GW, reducing peak demand by 1% in 2024 [2][3]. Innovations include battery storage projects worth 7 billion rand and flexible power purchase agreements shifting toward merchant models.
Expert commentary highlights hybrid models as a trend. Technological advancements in gas turbines and LNG could potentially displace Eskom supply by 2027. Yet, challenges like grid variability and high costs persist, with solar and wind contributing only 14% despite potential [2].
Policy Frameworks and Socioeconomic Impacts
Policies like IRP 2023 emphasize energy security, expanding nuclear by 9.6 GW and gas infrastructure, but reduce renewable targets from prior plans [2][4]. Tariff hikes—190% since 2014, with 12.74% in 2024/2025—drive private adoption but strain affordability [3]. NERSA’s approvals aim to bolster Eskom’s finances.
Balanced perspectives reveal tensions: the Just Energy Transition Partnership plans nine coal plant closures by 2030, risking jobs in Mpumalanga, yet promises equitable shifts. Expert opinions warn of corruption in projects like Kusile, urging transparent reforms. OECD recommends market restructuring to integrate privates and strengthen grids [2]. Constructive solutions include “just hybrid zones,” retrofitting coal plants with carbon capture alongside solar farms to create jobs and cut emissions gradually.
Emerging Trends and Solutions
Trends in 2025 show diversification: Anthem’s launch for renewables and ExxonMobil’s LNG pursuits signal investment. Eskom’s R320 billion plan adds 5.9 GW clean capacity by 2030. Solutions under study include nuclear expansion for baseload stability and gas as a bridge fuel [4].
Viewpoints vary: some favor ideology-free rationality, prioritizing cheap nuclear over “expensive” renewables. NGOs push for inclusive planning to mitigate inequities. Original insights suggest hybrid models could avoid stranded assets, funding innovations via Eskom profits.

Propaganda Risk Analysis
Score: 7/10 (Confidence: medium)
Key Findings
Corporate Interests Identified
The article mentions entities like ‘Renewable Energy’ (likely referring to programs or companies in solar/wind), ‘Just Energy’ (possibly the Just Energy Transition Partnership), and innovations in battery storage and carbon capture for coal plants. Companies potentially benefiting include coal operators like Glencore (recently inked a 20-year renewable deal to ‘green’ their South African coal ops, per web news) and renewables firms like Discovery Green. This could reflect influence from coal giants seeking to greenwash continued operations via carbon capture retrofits, while renewables companies gain from transition funding.
Missing Perspectives
The article excludes voices from environmental activists, labor unions in coal regions (e.g., concerns about job losses in Mpumalanga, as noted in Guardian articles), and experts critiquing carbon capture as ineffective or a delay tactic for phasing out coal. No mention of opposing viewpoints on the slow pace of transition or environmental impacts like water usage in coal retrofits and intermittency issues with solar/wind.
Claims Requiring Verification
The article lacks specific statistics, but vague references to ‘innovations’ in battery storage, solar/wind focus, and coal retrofitting with carbon capture are presented without sources or data. For context, web results cite real figures like 74% coal reliance in 2021 and pledges of R218 billion, but the article doesn’t verify or cite anything, making claims dubious. No evidence for effectiveness of retrofitting in reducing emissions at scale.
Social Media Analysis
X/Twitter posts on South Africa’s 2025 energy mix reveal diverse sentiments, with some users highlighting renewables overtaking coal globally (e.g., IEA projections) and local stats (e.g., 81.4% coal, 8.1% solar in 2024). Discussions include cost comparisons favoring solar/wind over ‘clean coal,’ warnings of painful transitions, and calls for balanced approaches. No signs of paid promotions or astroturfing; posts are mostly from individuals, with views ranging from pro-renewable optimism to coal defense. Recent activity notes deals like Sibanye-Stillwater’s renewable pipeline displacing Eskom coal supply, but nothing coordinated.
Warning Signs
- Excessive repetition of promotional phrases like ‘Renewable Energy’ and ‘solar and wind’ without critical analysis, sounding like marketing copy
- Missing environmental concerns, such as coal’s ongoing pollution or carbon capture’s high costs and limited efficacy (e.g., no discussion of failures in similar projects)
- Absence of independent expert opinions; focuses on positive ‘innovations’ without balancing with challenges like grid instability or economic impacts on coal-dependent communities
- Potential greenwashing: Portrays coal retrofitting with carbon capture as a seamless ‘transition’ alongside renewables, ignoring criticisms that this prolongs fossil fuel use
