What happens when global energy supply chains can no longer be trusted? Has the U.S. given up its edge in the clean energy race to China? And can politics keep up with the speed of the energy transition and the rise of AI? This week on Cleaning Up, Michael Liebreich sits down with former U.S. Energy Secretary Jennifer Granholm for a wide-ranging conversation on the future of global energy, politics, and clean technology. They explore how geopolitical tensions, from disruptions in the Strait of Hormuz to shifting alliances, are reshaping global energy markets and accelerating the move away from fossil fuels. Granholm offers an insider’s perspective on the impact of U.S. policy decisions under both Joe Biden and Donald Trump, including the rise, and partial dismantling, of the Inflation Reduction Act and what that means for US clean energy investment, manufacturing, and competitiveness. The discussion dives into the growing divide between ‘petrostate; U.S. and ‘electrostate’ China, the global race for dominance in electric vehicles and battery storage (with companies like BYD leading the charge), and the unintended consequences of tariffs and industrial policy. Looking ahead, Granholm reflects on lessons learned from her time in office, what a future Democratic administration might do differently, and the political and economic challenges shaping the road to the next presidential election 2028: inflation, energy affordability, and the disruptive impact of AI on jobs.

The news agenda this year has been entirely dominated by energy related stories, whether it's the war in Europe being pursued by Russia — formerly Europe's most significant energy provider — the U.S. capturing the head of state of Venezuela — which has some of the biggest oil reserves in the world — or the ongoing attack by Israel and the U.S. on Iran and all its ramifications. But there is also another story, which is the long term rift between the U.S. and the rest of the world about whether and how fast we should be addressing climate change.   This week on Cleaning Up, Michael Liebreich is joined by Dr Fatih Birol, executive director of the International Energy Agency, for his third appearance on the podcast. He discusses the International Energy Agency’s integral role in trying to steer the world through the current energy crisis, how he sees the global energy system change in response to the crisis, and how his organisation is facing up to criticism from the US over its net-zero scenarios. Fatih and Michael discuss: Why the current crisis could surpass the oil shocks of the 1970s How the International Energy Agency is helping stabilize global markets   Efficiency measures and the need to reopen the Strait of Hormuz Why solar, batteries, and nuclear may surge amid the chaos  Why countries are looking toward coal to fill the gap Whether energy security is now overtaking climate as the top priority The growing divide between the U.S. and global institutions on climate policy And why Birol insists: “Data always wins.” As Executive Director of the International Energy Agency, Fatih has positioned the Agency at the centre of global efforts to advance a secure, affordable, and sustainable energy system. Dr Birol joined the IEA in the mid-1990s and progressed from junior analyst to Chief Economist, where he oversaw the flagship World Energy Outlook.  He has been included in the TIME100 list of the world’s most influential figures and recognised by Forbes as one of the world’s most influential figures in energy. He chairs the World Economic Forum’s Energy Advisory Board and is an honorary life member of Galatasaray Football Club. This episode was recorded on March 19, 2026.

How should a central bank respond to energy shocks? Will high oil and gas prices bolster the uptake of renewables? And what is the true cost of net zero 2050? This week on Cleaning Up, host Michael Liebreich sits down with Pierre Wunsch, Governor of the National Bank of Belgium and member of the European Central Bank’s governing council, for a candid, behind-the-scenes discussion about how central banks should and can respond to inflation, energy volatility, and climate transition. From the recent surge in oil and gas prices to the lessons learned from post-COVID inflation, Wunsch explains why central banks may have “got it wrong” during the Russia-Ukraine energy shock, and how they’re rethinking their response to supply shocks. Michael and Pierre dive into: The costs of net zero, and why a one-size fits all approach to decarbonisation isn’t working. Whether European economies can absorb the costs transition without losing competitiveness Why “transitory inflation” didn’t stay transitory during the Russia-Ukraine war The risk of political backlash and policy instability Why industry, not households, is the hardest part of decarbonisation for Europe The gap between climate ambition and credible policy tools.

What happens if we’re underestimating the speed and scale of climate risk? This week on Cleaning Up, Bryony Worthington sits down with Ricken Patel, Principal at Climate Hub & Founder of activist network Avaaz, to explore how to build successful climate movements, and the case for research into geoengineering. Ricken argues that companies have been accidentally geoengineering since the turn of the Industrial Revolution, as a byproduct of their pollution, and says ‘it’s crazy’ that research into deliberate forms of geoengineering isn’t being allowed. Ricken has a long history as a campaigner and activist working in the climate and democracy spaces. He founded Avaaz, an online activism platform, and led successful campaigns around the Paris Agreement and beyond.  He was voted "Ultimate Gamechanger in Politics" by the Huffington Post, listed among the world's top 100 thinkers by Foreign Policy, and named a Young Global Leader by the World Economic Forum. Patel studied Philosophy, Politics and Economics at Oxford, graduating first in his class, and holds a Master's from Harvard's Kennedy School of Government. He went on to live and work on conflict resolution and civilian protection in Sierra Leone, Liberia, Sudan, and Afghanistan for organizations including the International Crisis Group. Together, Bryony and Ricken dive into: Why climate risks may be far greater than current models suggest The cooling effects we’re losing as we clamp down on pollution The  case for researching geoengineering How democracy, truth, and climate are deeply intertwined And how to build a successful movement around climate change.

This week on Cleaning Up, Michael Liebreich is joined by Emmanouil Kakaras, engineer, academic, and Senior Advisor at Mitsubishi Heavy Industries EMEA, for a grounded, technical conversation about the intersection of emissions and engineering: gas turbines pushing the limits of thermodynamics, the trade-offs between hydrogen, ammonia, and synthetic fuels, and why carbon capture keeps coming back into the conversation. Kakaras draws on decades in both academia and industry to explain how decisions actually get made inside large engineering companies, and why the energy transition isn’t about picking a single “winner,” but deploying a mix of solutions at scale.

This week on Cleaning Up, host Michael Liebreich sits down with Varun Sivaram and Steve Smith to explore one of the most urgent, and overlooked, challenges of the AI revolution: how to power it without breaking the grid. As AI demand explodes, hyperscale data centres are emerging as massive, inflexible loads, rivaling entire cities. But do they have to be a burden on the grid? This conversation dives into a groundbreaking trial led by Emerald AI in partnership with National Grid and NVIDIA—demonstrating that data centres can dynamically adjust their power consumption in real time using software. Key insights include: How AI data centres could reduce grid stress instead of increasing it The concept of “flexible demand” and why it’s a game changer for AI data centres Real-world trial results Why “speed to power” matters more than cheap electricity in the AI race How software, not infrastructure, could help unlock billions in grid capacity The hidden flexibility inside AI workloads (and why not all compute is equal) From kettle spikes during football matches to lightning strikes on the grid, this episode reveals how intelligent systems can respond in seconds, turning a looming energy crisis into a massive opportunity.

What happens when millions of electric cars become part of the energy grid? And could the key to cheaper, cleaner power already be sitting in your driveway? And why are so many automakers pushing back against EV targets?  This week on Cleaning Up, host Bryony Worthington speaks with Fiona Howarth, founder of Octopus Electric Vehicles, about the rapid transformation of the global car industry and the powerful role electric vehicles are beginning to play in the energy system. From her early fascination with clean energy to building one of the UK’s most innovative EV businesses within Octopus Energy, Fiona shares the inside story of how electric mobility moved from niche curiosity to mainstream disruption. She explains why falling battery costs, bold policy like the UK’s ZEV mandate, and fierce competition from Chinese manufacturers such as BYD are accelerating the transition faster than many expected.  The conversation explores how EVs are evolving beyond transportation. With vehicle-to-grid technology, cars could become distributed batteries: storing renewable power, stabilising the grid, and even providing drivers with free electricity for their journeys. It’s a vision that could reshape both the energy market and the economics of driving.  But as some companies race ahead, some traditional automakers are pushing back, asking for slower timelines. Fiona argues that the real risk isn’t moving too fast, it’s backing the wrong players in a historic technological shift.  Leadership Circle:  Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, Schneider Electric, SDCL and Wärtsilä.

How can we build out clean energy and infrastructure faster? Is Europe engineering its way to resilience, or pricing itself out of competitiveness? And can we redesign the entire system fast enough to keep up with AI, electrification and rising demand?  This week on Cleaning Up, Michael Liebreich sits down with Hilde Tonne, Chair of Arup and former CEO of Statnett, to explore the hard realities behind the energy transition. From offshore wind and nuclear to grid bottlenecks and data centre demand, Hilde brings a uniquely systems-level perspective shaped by decades leading infrastructure transformation across telecoms, energy and engineering.  They dive into:  Why grid investment, not generation, may be Europe’s biggest constraint  Whether hyperscaler AI companies should foot the bill for massive grid upgrades  The hidden bottlenecks in regulation, permitting and procurement • How ‘total design’ thinking can cut carbon by 40% before construction even begins  Whether electrification makes Europe more resilient, or more exposed  Hilde argues that this transition is no longer just about climate. It’s about security, competitiveness, affordability and economic growth. But achieving it will require rethinking regulation, redesigning infrastructure and the bureaucracy around it, and aligning public and private capital at unprecedented scale.  Leadership Circle:  Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, Schneider Electric, SDCL and Wärtsilä.

This week on Cleaning Up, host Bryony Worthington sits down with investor and energy strategist Laurent Segalen, co-host of the Redefining Energy podcast, for a sweeping conversation that spans carbon markets, uranium trading, battery innovation, and Laurent’s bold plan to connect Canada and Europe with a 5,000km subsea electricity cable. Laurent shares the personal moments that shaped his obsession with energy security, from witnessing Cold War division in Germany to cleaning an oil spill off the beaches of Brittany, and how those experiences led him to the heart of Europe’s carbon trading system and into high-stakes commodity markets. Along the way, Laurent recounts: How he became becoming one of the most profitable uranium traders on the market The financial mechanics behind interconnectors, and why east-west cables make money Why sodium batteries could reshape grid storage His experience designing carbon markets, and whether they are working or not. At the centre of the discussion is NATO-L (North Atlantic Transmission One Link): an audacious proposal to link Canadian hydro and wind to European markets through ultra-high-voltage subsea cables.

This week on Cleaning Up, Michael Liebreich sits down with Miguel Stilwell d’Andrade, CEO of EDP, one of the world’s leading clean energy companies. From the front lines of the energy transition, Miguel explains why electricity demand in the United States is exploding, driven by AI, data centres, and re-industrialisation, and why this could make renewables one of the most attractive investments of the decade. He also shares how EDP transformed itself from an 80% coal-based utility into a company generating over 90% of its electricity from renewables. But the transition hasn’t been entirely smooth. Miguel recounts the dramatic moment when Spain’s grid collapsed, taking Portugal down with it, and what it taught him about resilience, grid stability, and the hidden challenges of running a modern clean power system. They also dive into: Why soaring power demand is changing energy economicsThe real story behind renewable costs and rising electricity pricesThe link between European competitiveness and energy independenceThe political and economic reality of investing in US clean energyWhy resilience may define the next phase of the transitionThis episode was recorded prior to the recent storms in Portugal.

This week on Cleaning Up, Michael Liebreich sits down with carbon removal insider Robert Höglund, CEO of Marginal Carbon, co-founder of CDR.fyi and architect of MilkyWire’s Climate Transformation Fund, for a deep dive into what’s working and what’s not in carbon dioxide removal and corporate climate action. Drawing on five years of hands-on experimentation funding everything from biochar to direct air capture and policy advocacy, Höglund challenges the dominant “speed and scale” narrative. Instead, he makes the case for a new phase: prove and learn.  Together, Michael and Robert unpack why the highest-impact climate interventions are often the least measurable, why corporate net-zero targets are more conditional than we admit, and what it will actually take to make carbon removal credible, scalable, and worth paying for.

What if the future of clean energy isn’t decided in Washington, Brussels, or Beijing, but in Lagos, Nairobi, and Addis Ababa? Are we underestimating how fast the Global South is leapfrogging fossil fuels? And what happens when clean energy becomes the cheapest, fastest path to development, not a climate sacrifice? In this episode of Cleaning Up, Michael Liebreich is joined for a third time by Damilola Ogunbiyi, CEO and UN Special Representative for Sustainable Energy for All and Co-Chair of UN Energy. Together, they explore how Africa and the wider Global South are quietly reshaping the global energy transition, from rapid growth in solar, storage, mini-grids, and EVs to bold policy moves that many developed economies haven’t dared to make. They dive into why energy access is about dignity, health, and gender equality; why finance, not technology, is the real bottleneck; and how local capital, data, and innovation could determine whether “Most of World” powers its future with clean energy or fossil fuels.

How do we model the climate system? How warm will 2026 be? And can geoengineering be anything more than a bandaid?  This week on Cleaning Up, Bryony Worthington sits down with leading climate scientist Dr. Zeke Hausfather on the day the 2025 global temperature data is released. Despite a La Niña year, the planet has just experienced one of its hottest years on record — pushing us ever closer to the 1.5°C threshold. Zeke explains why recent warming has accelerated, how declining air pollution may be unmasking hidden heating, and what disappearing cloud cover could mean for climate sensitivity.  The conversation ranges from the surprising accuracy of early climate models, the risks of rising nationalism, and what the U.S. withdrawal from international science means for the world.  They also tackle controversial questions:  Are worst-case climate scenarios still plausible? Is geoengineering a dangerous distraction — or an emergency brake? And can carbon removals ever work economically at scale.

Why does Africa, home to 18% of the world’s population, receive just 1% of global energy investment? What’s stopping money from flowing to the continent when it has such good wind and solar potential? And what would it take to unlock an energy boom that benefits both Africa and Europe? Spread across 54 countries and with a combined GDP the size of Italy, Africa's population is young and growing rapidly. It is set to grow from 1.5 billion people today to 2.5 billion by 2050. And it could reach 4 billion by 2100, accounting for two out of every five people on the planet.  Africans want and deserve the same prosperity shared by richer parts of the world. And that means investment. So why is investment not flowing?  This week on Cleaning Up, Michael Liebreich speaks with Clemens Calice, CEO and founder of Cygnum Capital, which invests around $1.3 billion in Africa’s energy transition. Together they explore why risk perception and outdated models are slowing investment across Africa.  From rooftop solar for factories and mines, to electric motorbikes, power pools, and the geopolitics of gas, this episode makes the pragmatic case for how Africa can leapfrog to a cleaner, more resilient energy future.
