Cleaning Up: Leadership in an Age of Climate Change

Is the future of clean energy and climate solutions brighter than we think? In this episode of Cleaning Up, Michael Liebreich welcomes back Hannah Ritchie — Deputy Editor at Our World in Data, researcher at the Oxford Martin School, and author of her new book, Clearing the Air.In Clearing the Air, Hannah tackles 50 of the most common myths and misconceptions about climate solutions, from “Isn’t climate action too polarised and politically divisive to fix?” to “What happens when the wind doesn’t blow?” and “Won’t the world run out of minerals?” Hannah dives into the data behind renewables, electric cars, nuclear power, grids, and even lab-grown meat — cutting through the noise with clarity.Michael quizzes Hannah on why she wrote the book and what she hopes to achieve with it, and whether it has the potential to change the minds of climate skeptics. This conversation offers a grounded, accessible look at what really works, what doesn’t, and why we should feel more hopeful than the doom-filled narratives suggest.Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Arup, Cygnum Capital, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

What happens when cheap solar flips the script on climate sceptics? Can pumped hydro really deliver the long-duration storage we need? And is “hope” a dangerous comforter in the race to net zero?In this season opener of Cleaning Up, Michael Liebreich sits down with Malcolm Turnbull — former Prime Minister of Australia, lawyer, statesman, energy investor, and climate champion. From leading Australia through fierce political battles over climate policy to now spearheading renewable projects through Turnbull Renewables, he offers a rare insider’s perspective on the global clean energy transition.Turnbull and Liebreich explore the clash between optimism and realism in climate action: why cheap solar is reshaping politics, the promise and pitfalls of green hydrogen, and whether pumped hydro could be the long-duration storage solution the world needs. Along the way, they reflect on U.S. politics under Trump, trade negotiations without American leadership, and why “hope is not a strategy” when it comes to energy security.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Arup, Cygnum Capital, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

This episode was originally broadcast in April 2022Alex Honnold is one of the world’s best rock climbers, famous for his free solo ascents of big walls, including his 2017 first free solo of El Capitan in Yosemite.Alex began studies in engineering at the University of California-Berkeley but dropped out to pursue his passion for climbing, living out of his van. He first attracted attention within the climbing community in 2008 when he became the first climber to free solo Half Dome in Yosemite. In 2012 he established the speed record for the Yosemite Triple Crown, climbing three big walls in under 19 hours. With Hans Florine, Alex climbed the popular Nose of El Capitan, a nearly 3,000-foot granite wall, in a record time of two hours 23 minutes and 51 seconds – a feat National Geographic described as perhaps " the greatest feat of pure rock climbing in the history of the sport."Alex has been profiled by 60 minutes and the New York Times, appeared on the cover of National Geographic and starred in numerous adventure films. In 2015, together with professional climbing writer David Roberts, he authored Alone on the Wall, the story of seven of his greatest climbing feats up to that year.In 2012 Alex founded the Honnold Foundation to provide solar power to some of the disadvantaged communities he was coming across in his climbing career. In 2021 the Foundation supported 44 communities across 17 countries with its brand of community-centered innovation catalysed by solar energy.Links and more:Watch the video of this episode: https://youtu.be/MwmQf0mhHkEHonnold Foundation: https://www.honnoldfoundation.org/Free Solo Trailer: https://www.youtube.com/watch?v=urRVZ4SW7WUFree Solo website: https://films.nationalgeographic.com/free-soloThe Ascent of Alex Honnold – CBS special report with Lara Logan https://www.youtube.com/watch?v=SR1jwwagtaQEduro Corner: The most exposed move of Alex’s Free Solo climb of El Capitan https://www.youtube.com/watch?v=blfR33DUqsgProject Bo: https://www.projectbo.org/Project Bo, lessons learned: https://www.liebreich.com/project-bo-saving-lives-in-sierra-leone-with-solar-batteries-and-twitter/

What if the energy transition isn't a race, but a steady march toward the end of fossil fuel usage? Do we need to move more like the tortoise, and less like the hare? And in a world of competing narratives, who gets to define "pragmatism"?In this season finale of Cleaning Up, hosts Michael Liebreich and Bryony Worthington unpack these questions as they review Season 15's most compelling conversations about energy transformation, and celebrate five years of Cleaning Up. They dissect the current political landscape, particularly the challenges facing clean energy in the United States, and Bryony grills Michael on his recent Bloomberg essay on the "Pragmatic Climate Reset."This is the final episode of Season 15 of Cleaning Up, join us in September for the start of Season 16.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

In February, veteran fossil industry advisor Dan Yergin and two co-authors published a piece called The Troubled Transition. In it they dismiss the idea that there is or can ever be an energy transition, anchored on the fact that fossil fuels contributed 85% to so-called primary energy in 1990 and still contribute 80% today. Needless to say, their argument has been widely amplified by the oil and gas industry. They conclude with a demand for a new approach – which they call a “pragmatic path”. Pragmatism is needed, but not the pragmatism of defeat. Not the ‘pragmatism’ of believing fossil fuels hold the key to further human progress. Not the ‘pragmatism’ of addressing climate change only if it suits the interests of fossil-fuel companies. What is needed is the pragmatism of robust but affordable climate action. This week on Cleaning Up, Michael Liebreich debunks narratives that trumpet the alleged failure of climate action, and explains why a pragmatic climate reset is needed.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

Is the US about to enter a new era of energy inflation? Can technological progress outpace political regression? Are we witnessing the permanent end of America's climate ambitions?This week on Cleaning Up, Michael Liebreich sits down with Ethan Zindler, former climate counselor to Treasury Secretary Janet Yellen, now head of countries and policy at BloombergNEF, to dissect the dramatic shifts in US energy policy. Fresh from the passage of the "One Big Beautiful Bill," Zindler reveals how recent legislation in the US could set back clean energy development by years, potentially undermining investments in wind, solar and electric vehicles. There are a couple of brighter spots too, with costs in some technologies falling so rapidly that they might escape the drag of the current administration, and other technologies — like advanced geothermal and nuclear — seeing an uptick in support. Zindler brings the latest analysis from BloombergNEF to Cleaning Up to help unpack the One Big Beautiful Bill and what it means for the future of US energy policy.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

⁠If the UK can’t ditch fossil fuels, who can? What impact would more drilling in the North Sea have for UK energy prices? What does the end of the net zero consensus mean for UK energy policy?This week on Cleaning Up, host Bryony Worthington sits down with Tessa Khan, founder of Uplift, a charity challenging the oil and gas industry's hold on UK energy policy. A lawyer turned campaigner, Khan offers incisive analysis of why the North Sea's fossil fuel era must end.Drawing from her background in international human rights and development, Khan reveals how the UK could become a global pioneer in energy transformation. She unpacks the economic myths perpetuated by the oil and gas lobby, exposes the minimal benefits of continued extraction, and champions a just transition to renewable energy.With the UK at a critical political crossroads, Khan offers a masterclass in strategic advocacy, blending data, political insight, and a passionate vision for a sustainable future. Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

What if the key to solving our climate crisis lies beneath our feet? Could tiny fungal networks be the unsung heroes of carbon sequestration? And how might reimagining our relationship with fungi transform our understanding of life on Earth? This week on Cleaning Up, Bryony Worthington sits down with Merlin Sheldrake, author of the bestselling "Entangled Life," to explore the extraordinary world of fungi. Sheldrake reveals how these remarkable organisms are not just passive participants in our ecosystem, but active innovators that have been shaping our planet for a billion of years. From their crucial role in carbon cycling and soil health to their potential in creating sustainable materials, fungi may be a powerful solution to some of our most pressing environmental challenges. Sheldrake takes us on a journey through fungal networks, discussing their intelligence, chemical capabilities, and symbiotic relationships that challenge our understanding of life. Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

In a world where 17% of all electricity is generated from wind and solar and where 93% of all new capacity added to the grid is from renewables, it can be easy to forget that countries got their first wind and solar resources within just the last few years. And in fact, some countries are still waiting for their first. Today on Cleaning Up, we’re joined by Daniel Calderon, Founder and Managing Partner of Alcazar Energy Partners. Daniel has made it a specialty of going into countries overlooked by others, building their first wind and solar farms, and as he explains, doing it profitably. Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.
