[Episode #276] – Electricity Reform in South Africa

May 20 2026

Mini Episode

This is the second part of a miniseries about South Africa's energy transition, based on Chris' travels there in September and October of 2025. The first part was Episode 264, in which we heard how the end of apartheid precipitated reform of the country's energy systems.

South Africa is arguably one of the most exciting places in the world to see the energy transition unfolding right now, because after nearly 150 years of relying almost exclusively on coal for its energy, it is finally implementing reforms that will allow its electricity system to integrate more renewables onto its grid.

Eskom, the state-owned monopoly, has owned and controlled the grid for over a century. Its aging coal fleet still provides around 80 percent of the country's electricity, even though solar power is now far cheaper, and it has been able to block new renewable projects because they threatened its coal business. But now Eskom is being broken up into separate units for generation, transmission, and distribution. And the country is launching its first wholesale electricity market — the South Africa Wholesale Electricity Market, or SAWEM — opening the door for renewables to compete with coal.

At the same time, there is also an enormous and growing informal supply in the form of distributed solar — enough to meet a quarter of the country's electricity demand. Many businesses and residents are installing their own solar and battery systems, often without any kind of permission from or notice to the utility. That is simultaneously creating an entirely new and complex sort of electricity system that's hard for utilities to manage, while also making the system far more resilient. In fact, distributed solar batteries are credited with putting an end to the "load shedding" blackouts that plagued customers for over 15 years.

Formally and informally, South Africa is rushing headlong from its coal-fired past and into the renewably powered future. Clean generation led by solar surged past 30 percent in late 2025, while coal fell to a record monthly low. South Africa's experiment in restructuring a vertically integrated, coal-dependent grid offers an early look at the politics, economics, and surprises that other markets will face as they take on their own transitions to renewables.

In this episode, we'll be hearing from experts who are closely involved with the electricity reforms in South Africa. In the next episode, we'll see how those reforms play an important role in delivering a just transition.

[Episode #275] – The Cost of Delay

May 6 2026

Mini Episode

In mid-2026 we're experiencing the largest energy crisis the world has ever faced. The sudden and prolonged disappearance of one-fifth of the global supply of oil and LNG, set in motion by the Iran war we covered in Episode #272, has sent import costs soaring. World leaders are now confronting the risks of fossil fuel dependence as never before.

The high costs and outright physical shortages of oil and gas are driving inflation across the global economy. But that's not all. The crisis is also weakening currencies in importing economies, deepening their debt, stalling growth, and transferring wealth on an enormous scale. By 350.org's count, more than $150 billion has already moved from ordinary households into the balance sheets of oil and gas companies.

A new report from 350.org, Out of Pocket: How Delaying Global Fossil Fuel Phase Out is Draining Households and Economies, puts hard numbers on the price of delaying the energy transition. In today's conversation, we welcome the lead author, Clémence Dubois, Global Campaign Manager at 350.org, to share its findings. Clémence explains how the delay imposes opportunity costs, economic and environmental justice costs, and national security risks on importing countries. She makes the case for why this crisis, unlike the six previous oil shocks, might be the final nail in the coffin of the world's dependence on imported oil and gas. And we'll see how many countries are already switching to domestic renewables and electrification — because for them, delay is no longer an option.

Guest:

Clémence Dubois is Head of Global Campaigns at 350.org, an international NGO that uses online campaigns, grassroots mobilizations, and mass actions to oppose fossil fuel projects, deprive multinationals contributing to climate change of their financial resources, and mobilize for a just transition. A key figure in civil society for the past ten years, she holds an MSc in International Regulation and Environmental Policy from the London School of Economics and one in Political Sciences from Sciences Po Lille.

[Episode #274] – Global Electricity Review 2026

Apr 22 2026

Mini Episode

For years, transition skeptics have argued that what's really happening globally is "energy addition," where renewables are piling on top of fossil fuels rather than pushing them aside. The data that's just landing from 2025 finally puts that argument to rest.

For the first time, global electricity generation from fossil fuels fell, not because of a pandemic shutdown, recession, or unusual weather, but simply because renewables grew faster than demand. Power-sector emissions dropped along with it, also a first. Solar recorded the largest single-year increase of any electricity source on record, with the exception of coal's rebound as the world re-opened after 2020. And renewable generation surpassed coal in the modern era for the first time.

These are just a few of the important findings in Ember's Global Electricity Review 2026. To unpack what they mean, and what they don't, we welcome back to the program Nicolas Fulghum, Senior Energy and Climate Data Analyst at Ember and one of the report's lead authors. Nic was last on the show in Episode #254 reviewing the 2025 edition of this report, which became our most popular episode of the year, and which we re-released without paywall in Episode #266.

In today's show, we'll see how the structural decline in fossil generation, long-anticipated by transitionistas, finally arrived. We'll hear why solar's growth rate refuses to slow even as the technology matures. And we'll explore how the second fossil fuel shock of the decade, this time from the Iran war we covered in Episode #272, is pushing more countries to accelerate their move off imported fuels. The energy transition isn't coming. It's here, and it's getting more unstoppable every year.

[Episode #271] – China Update 2026

Mar 11 2026

Mini Episode

China's total CO2 emissions went flat and slowly started declining almost two years ago, but you probably wouldn't know it from reading the news about how its pipeline of coal power plant projects surged to a record high in 2025.

Similarly, recent data shows that China's coal power output fell by 1% in 2025, even as it built more coal plants than it had in a decade.

These kinds of conundrums are typical for China, with its complex interaction of economic forces and top-down state planning. But once you understand what's driving them, it all makes sense—just not a Western economic kind of sense.

To help us untangle this picture, we welcome back Lauri Myllyvirta, co-founder and lead analyst at the Centre for Research on Energy and Clean Air (CREA), who last joined us in Episode #138, all the way back in 2021. We were overdue for an update.

In this episode, we dig into this coal conundrum—why China added 78 GW of new coal capacity in 2025, more than India built in an entire decade, even as customers pay $14 billion a year in capacity payments to coal plants that may not even run. We look at the 315 GW of solar and 120 GW of wind China added last year, and how 75 GW of new storage is helping to displace coal power. And we discuss why China's clean energy investments now make up more than a third of its GDP growth—without them, 2025 growth would have been 3.5% instead of 5%.

Although its fleet of coal power plants continues to grow, there is good news here. Because as the largest energy consumer in the world, China's declining emissions mean emissions are declining globally.

[Episode #269] – Trump’s War on the Energy Transition

Feb 11 2026

Mini Episode

In the first year of his second term, President Donald Trump waged an all-out war on the energy transition. His administration canceled hundreds of projects created under the Inflation Reduction Act, IIJA, and CHIPS Act, blocked offshore wind farm development, and forced aging fossil-fueled power plants to continue operating after their utility owners planned to shut them down. It weaponized every federal agency from Interior to the Department of Commerce against renewable energy, seized Venezuela's oil, and pulled the US out of participation in key UN climate bodies.

The results have been staggering. Over 22 GW of wind and solar projects have been thwarted or thrown into limbo, and fully half of the country's planned new power capacity, some 117 GW, is at risk of delay. The Department of Energy has issued "emergency" orders to keep six aging coal and gas plants open, invoking a provision of the Federal Power Act originally written for wartime. None of these federal interventions were requested by a utility, grid operator, or state regulator. Courts have been pushing back hard, calling these actions arbitrary, capricious, unreasonable, and seemingly unjustified.

Whether any of these executive actions will survive is the central question. In today's conversation, we are rejoined by Ari Peskoe, Director of the Electricity Law Initiative at Harvard Law School, to walk through dozens of Trump's energy interventions and assess which ones are likely to hold up against the growing wave of legal challenges being brought against them. As we discuss, the courts are doing a surprisingly effective job of striking down the administration's illegal maneuvers. But every project delayed or canceled while the cases grind through court is inflicting real damage on the energy transition.

[Episode #265] – IEA World Energy Outlook 2025

Dec 17 2025

Mini Episode

In November, the International Energy Agency (IEA) released its annual World Energy Outlook (WEO) report. It was greeted with cheers from the fossil fuel industry and jeers from energy transitionistas, but there is much more to the report than either camp's narratives suggest. So Chris returned to IEA headquarters in Paris to discuss the WEO with lead author Tim Gould, as he has done for the past two years (Episode #215 and Episode #248), to get the story straight from the source.

What he found is that the revived Current Policies Scenario (CPS) shows what could happen if the energy transition is stopped in its tracks and fossil fuel demand continues to grow, as the Trump administration has stated it would like to see. While other scenarios explore continued progress in energy transition consistent with recent reports, where oil demand still peaks around 2030, and coal demand falls before the decade ends.

The report's updated global data tells another story. The oil industry spends $550 billion annually on upstream development, and 90% of that just keeps production flat. Meanwhile, 45% of new heavy freight trucks sold in China this year run on electricity or LNG, not diesel. And in the Middle East, solar is increasingly displacing oil for electricity generation and desalination of water. In Saudi Arabia alone, this could free up over a million barrels of daily consumption.

In fact, in this year's report, IEA declares that "the Age of Electricity is here." For the first time, more than half of all energy sector investment is flowing into electricity. Renewables grow "faster than any other major energy source in all scenarios."

The picture is clear: the energy transition is still going strong.

Tim Gould is co-head of the World Energy Outlook series at the Paris-based International Energy Agency (IEA). He designs and directs the work together with the IEA’s Chief Energy Modeller and contributes to the Outlook as a principal author. He also oversees the Agency’s analysis of energy investment and finance, including the World Energy Investment series. Tim has been at the IEA since 2008, and joined initially as a specialist on Russian and Caspian energy before going across to join the World Energy Outlook team under the (then) Chief Economist, Fatih Birol, who is now the IEA’s Executive Director. Before IEA, he worked on European and Eurasian energy issues in Brussels and also spent ten years working in Eastern Europe, primarily in Ukraine.

[Episode #264] – History of the Transition in South Africa

Dec 3 2025

Mini Episode

South Africa has earned a reputation for having an old, backward, and unreliable electricity system more dependent on coal than any other country with a similarly sized economy. With an aging fleet of coal-fired power plants owned by a century-old utility that has actively resisted the energy transition, its grid is ripe for modernization.

South Africa is also blessed with largely untapped wind, water, and solar resources that could meet all of the country's energy needs several times over. Few countries better exemplify both the challenge and opportunity in the energy transition.

That transition is now under way, both through deliberate official reforms and through an uncontrolled explosion of solar and batteries that customers are installing on their homes and businesses. Over seven gigawatts of behind-the-meter solar and storage now operate in a country whose grid demand rarely exceeds 30 gigawatts, all deployed with zero subsidies.

To explore this story, Chris traveled to South Africa in September 2025 for a six-week research trip. He recorded numerous interviews with people closely involved in the country's energy transition, which we are featuring in a new miniseries.

We begin with Anton Eberhard, Professor Emeritus at the University of Cape Town's Graduate School of Business. For more than 35 years, Anton has worked to modernize and liberalize South Africa's power sector in pursuit of a more equitable, just, and clean energy system. His commitment to justice runs deep: in 1977, he became one of the first white South Africans imprisoned for refusing conscription into the apartheid military. After his release, he pursued a PhD in solar energy around 1980, doing fieldwork in remote Lesotho villages long before renewables were economically viable.

In this conversation, Anton recounts the evolution of South Africa's power sector alongside his own personal history. He explains why Eskom, once named the best utility in the world, saw its energy availability factor plummet from over 90% to as low as 40% at the height of the country's power crisis. He describes the political economy keeping coal interests entrenched, his role in the groundbreaking 1998 white paper whose proposed reforms are only now, 27 years later, being implemented, and why structural changes remain critical for accelerating the energy transition. This will give you the essential context for the rest of our South Africa miniseries, and contains many universal insights that may be useful to understanding the energy transition wherever you live.

Guest:

Anton Eberhard is a Professor Emeritus and Senior Scholar at the University of Cape Town’s Power Futures Lab in the Graduate School of Business. His research, teaching and advisory work focuses on governance and regulatory incentives to improve utility performance, power investment challenges, the design of new power markets, distributed energy resources and linkages to electricity access and sustainable development.  Prof Eberhard was a member of the Global Commission to End Energy Poverty. He has worked in the energy sector across SubSaharan Africa, and other developing regions, for more than 35 years and was the founding Director of the Energy and Development Research Centre. He is a Foundation Member of the Academy of Science of South Africa. He was appointed by the President of South Africa to chair a task team to resolve serious financial and technical challenges in the national utility, Eskom, and to make proposals on the restructuring of the power sector and he currently provides technical assistance to the National Energy Crisis Committee. Previously he has served on the country’s Ministerial Advisory Council on Energy, the National Planning Commission, the National Advisory Council on Innovation, and the Board of the National Electricity Regulator of South Africa. In 2012, he received the SA National Energy Association’s award for outstanding and sustained contributions to the enhancement of the South African energy environment. Prof Eberhard has more than 150 peer reviewed publications to his credit including three recent books: Independent Power Projects in SubSaharan Africa; Power Sector Reform and Regulation in Africa; and Africa’s Power Infrastructure: Investment, Integration and Efficiency.  He has undertaken numerous assignments for governments, utilities, regulatory authorities, donor and multi-lateral agencies, banks and private sector companies.

[Episode #242] – IEA Outlook 2025

Jan 29 2025

Mini Episode

What important trends are shaping the energy transition today? And what is the outlook for oil and gas demand?

In this conversation, Tim Gould of the International Energy Agency (IEA) returns to discuss key insights from the agency’s flagship annual report, the World Energy Outlook 2024. We consider the enormous implications of IEA’s view that global demand for all fossil fuels will peak and begin a slow decline within the next five years. To explore this, we take a closer look at the state of the oil and gas industry, comparing its expectations to what climate science and energy system modeling tell us about the future of fossil fuels. We also consider how the energy transition could reduce overall demand for fossil fuels, creating excess supply imbalances that reshape global markets and trade geopolitics.

Our discussion also touches on the IEA’s forecast that low-emission electricity sources like solar, wind, and nuclear will account for more than half of global power generation before 2030. Further, we explore the rising energy demand from data centers, shifting expectations for hydrogen, and the investments needed to keep clean energy growing at a pace that meets our climate targets.

[Episode #204] – Regulatory Reform

Aug 9 2023

Mini Episode

Whose job is it to lead the energy transition?

In previous episodes, we’ve talked about how markets can guide the transition, especially after targeted reforms. We’ve considered the role of regulators, and the problems of regulatory capture and corruption. We’ve asked how local community leaders and elected officials can lead the energy transition from the bottom up, and conversely, how local activists can hinder and undermine the energy transition. We’ve also looked at the role of governments, particularly where no one else seems able to meet a particular challenge, or where that challenge isn’t really anyone’s responsibility.

In this episode, we try to knit together these disparate threads with veteran regulator Audrey Zibelman, who has held senior roles at both utilities and regulatory bodies for more than 30 years. Audrey shares some deep thoughts about why regulators and governments will have to play much more creative, courageous, and ambitious roles in the future to contend with the challenges of the energy transition.

[Episode #203] – The Case for Climate Optimism

Jul 26 2023

Mini Episode

Why does so much media coverage of climate change emphasize the worst-case scenarios and the slow speed of the energy transition? Why don't more stories highlight how the energy transition is working and accelerating, reducing expected increases in carbon emissions and rendering the worst-case warming scenarios increasingly unlikely?

These are important questions, because reporting about the climate and the energy transition can be a self-fulfilling prophecy. If the media constantly asserts that climate change is unstoppable and that we’re doomed, people will feel discouraged and give up during a critical time in which we must make progress. Whereas by showing people how they can be part of the solution, they will do what they can and support leaders committed to addressing the problem.

It’s also important that we understand what’s real and likely, and what isn’t. An unfortunate number of stories about climate change have emphasized vague “tipping points” and “feedback loops” that might accelerate warming in the future. But those are unquantified and undefined terms referring to highly uncertain possibilities. Meanwhile, highly probable outcomes that would result from existing climate policies are barely mentioned.

So why is there so much media focus on the worst-case scenarios? A shred of uncertainty isn't a sufficient reason to emphasize the worst case above all else. Wouldn't it make more sense to focus on the likely outcomes of our existing policies?

In this episode, we're joined by a climate researcher and data analyst who finds reason for optimism on climate change. Hannah Ritchie is a Senior Researcher in the Programme for Global Development at the University of Oxford. She is also Deputy Editor and Lead Researcher at the online publication Our World in Data, which brings together the latest data and research on the world's largest problems and makes it accessible for a general audience. Her forthcoming book, Not the End of the World, will be published in January 2024.

In today’s conversation, Hannah explains what converted her from a climate pessimist to an optimist, and shares her insights into why stories of climate doom seem to be more popular. We explore a number of her data analyses that support her optimistic outlook. And we discuss why it’s important to give people hope that we can address the climate challenge successfully—not by merely adopting a pollyannish attitude, but by really looking at the facts, and understanding the progress that we’re actually making.
