Cleaning Up Redux: From Free Solo to Free Solar — Alex Honnold
8/20/2025
This episode was originally broadcast in April 2022
Alex 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.

The End of Fossil Fuels Is Inevitable | Ep221: Michael Liebreich & Bryony Worthington
8/13/2025
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.

Audioblog 15: The Pragmatic Climate Reset Part 1 — The Energy Transition Is Not Dead
8/6/2025
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 explains what a Pragmatic Climate Reset entails.

The Inflation Induction Act: How the US Lost The Race for Clean Energy | Ep 219: Ethan Zindler
7/30/2025
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 some bright spots too, with costs in some technologies falling 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 joins Cleaning Up, bringing the latest analysis from BloombergNEF to unpack the One Big Beautiful Bill and what it means for the future of US energy policy.

The Best Markets for Wind and Solar Are Not Where You Think | Ep216: Daniel Calderon
7/10/2025
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.

NVIDIA Rising: Will The AI Boom Bust The Planet? | Ep215: Josh Parker
7/2/2025
In 1849, when the Gold Rush hit California, the people who were certain to make money were not the miners, but the sellers of picks and shovels. Indeed, America's first millionaire, Samuel Brannan, made his fortune by adding huge margins to everyday items that suddenly become high in demand.
Today's sellers of picks and shovels are those providing the hardware and infrastructure to the software and platform providers, and one company stands apart as the beneficiary of the recent boom times in artificial intelligence: Nvidia.
They're currently among the top three listed companies in the US, alongside Apple and Microsoft, and are incredibly profitable, with estimated margins in excess of 40%. They've been around for 30 years, and are much more than simply chip fabricators.
This week on Cleaning Up, Bryony Worthington sits down with Josh Parker, Nvidia’s head of sustainability, to explore some of the challenges and opportunities he sees in the AI and Climate space.

Is There A Future Without Oil & Gas? Ep214: Ben van Beurden
6/25/2025
Oil and gas companies lie at the heart of the energy transition. To some, they are heroes, continuing to power human progress despite all the odds. To some, they are villains, responsible for the climate change that is devastating our planet.
This week on Cleaning Up, Michael Liebreich interviews Ben van Beurden, former CEO of Shell from 2014 to 2023. The conversation explores the complexities of the energy transition, climate change, and the role of oil and gas companies in addressing global emissions.
Van Beurden argues that there's no silver bullet solution to climate change, emphasizing the need for multiple approaches and a holistic view of energy transformation. He believes oil and gas companies will play a crucial role in developing clean energy solutions and driving systemic change, but ultimately we must move away from polluting fossil fuels in pursuit of the prize of Clean Energy.

Renewables Are Here To Stay. Get Over It. | Ep211: Antonio Cammisecra
6/4/2025
The world's electricity system is transforming: We're integrating more and more variable renewables. Fossil plants are running fewer hours. Demand is growing everywhere, including in the developed world, as we electrify transport and heating, and AI data centers elbow their way onto the grid.
Some people find this very threatening but not Antonio Cammisecra, CEO of ContourGlobal. CounterGlobal is a leading independent power producer who is well on their way to transition away from coal to electricity production based on renewables and gas.
Antonio joins Michael on Cleaning Up to discuss how to build resilience and security in renewable-dominated grids, how ContourGlobal's battery storage systems are delivering solar at night, and why grids around the world are struggling to cope as electricity demand rises.

Is The Tide Turning On Hydrogen? Ep210: Andrew Forrest
5/28/2025
Billionaire iron magnate Andrew Forrest believes he's on the cusp of a breakthrough to decarbonise shipping and heavy industry using hydrogen.
As the Executive Chairman of the Fortescue, one of the world's largest iron ore companies, Andrew Forrest is not an easy to pigeonhole industrial billionaire. He built Fortescue into a hugely successful company, partly thanks to his belief in taking unconventional paths.
After a serious accident meant he had to take a break from work, he enrolled in a PhD in marine science. For over a decade now, has been very vocally committed to getting his company's practices aligned with a climate-safe pathway. More recently, he's also been shaking fellow CEOs and leaders out of climate complacency by highlighting the risks of lethal humidity.
This week on Cleaning Up, Bryony Worthington asks Andrew about the current climate crusade he's on, what he makes of the recent policy decisions taken by the International Maritime Organization (IMO) to agree carbon penalties for highly emitting ships, and if hydrogen can compete with renewables to be the power source of the future.

Can You Run a Grid Entirely On Renewables? Ep208: Anders Lindberg
5/14/2025
Can You Run A Grid Without Fossil Fuels?
"Yes," says Anders Lindberg, President of Energy and Executive VP at Wärtsilä, on this week's episode of Cleaning Up. It'll just cost €65 trillion extra by 2050.
Anders' team at Wärtsilä has recently published its Crossroads to Net Zero report, which argues that keeping a little bit of flexible generation on the grid will save huge amounts of money as the globe strives for net zero, while also speeding up the transition to renewables. The argument centres on what to do with the last few percent of power supply, and what forms of generation need to be built to ensure consistent electricity supply and prevent black or brown outs.
Perhaps unsurprisingly for a gas engine manufacturer, Wärtsilä's report makes the case that gas should provide the last few percentage points of electricity generation. Michael Liebreich puts that claim to the test.

Is Geothermal The Future For Oil & Gas? Ep207: Jamie Beard
5/7/2025
Geothermal seems to have found new favour under Donald Trump's presidency, but can it ever live up to its potential? Will the oil and gas industry reinvent itself before becoming obsolete? And how might geothermal energy change the global energy landscape?
This week on Cleaning Up, Bryony Worthington talks to Jamie Beard, founder of Project InnerSpace, about why geothermal energy has never lived up to its hype, and whether it has the potential do so. Currently generating less than 1% of global energy, Beard believes that geothermal could become a game-changing technology that can leverage existing drilling expertise from the oil and gas sector to provide 24/7 energy.
Beard breaks down the technical and economic challenges facing geothermal energy, exploring its potential to provide stable, clean power and heat across different global regions. From the United States to India, she outlines how next-generation geothermal technologies could offer a more consistent renewable energy solution.
This conversation was recorded live at Geothermal House, as part of San Francisco Climate week.

Uniper Rising: Can Germany's Gas Giant Go Green? Ep206: Michael Lewis
4/30/2025
When Russia unleashed its illegal and unprovoked invasion of Ukraine in February 2022, gas prices in Europe spiked by a factor of 10, driving a wave of bankruptcies and restructurings of European energy companies. Uniper was one of those.
Uniper is one of Germany's largest energy companies. It is active across more than 40 countries and has 19.5 GW of power generation capacity to its name. It was one of the funders of the built-but-never-used Nord Stream 2 gas pipeline that connects Russia to Germany and, for most of its history, was heavily reliant on Russian gas.
So when the gas taps from Russia were turned off, Uniper reported losses of $40 billion — the highest losses in German corporate history — and was subsequently nationalised by the German government. The company has since returned to profitability under its new CEO, Michael Lewis, our guest this week on Cleaning Up.
Michael Lewis joins Michael Liebreich to discuss the company's rise from the ashes, and how it plans to reach its climate targets and overcome the dunkelflaute.

Trump vs The Transition, The Pope’s Climate Legacy & The High Price of UK Electricity — Ep205
4/23/2025
In 100 short days, the world has transformed. Since the reelection of President Donald Trump, US federal climate policy has largely been abandoned, with the government seeking to reopen coal-fired power plants and lower environmental standards.
An escalating trade war and global tariffs has sent the rest of the world reeling and threatened the global financial system with collapse. China has come under particular fire, but the US has also targeted its closest allies and neighbours — Canada, Mexico and the EU — with tariffs.
Any sense of certainty has been thrown out of the window as a more inward looking US seeks to reshape the global order. So what does all this mean for the energy transition, and plans to reach net-zero? Michael Liebreich and Baroness Bryony Worthington join forces for the opening episode of Season 15 of Cleaning Up to discuss.

We Built a Solar System That's Saving Babies’ Lives — Ep204: Project Bo, Sierra Leone
4/9/2025
In Sierra Leone, a 20-minute power cut can be the difference between life and death for newborn babies.
In 2013, an extraordinary doctor called Dr Niall Conroy set up a neonatal intensive care unit at the Bo Government Hospital, in Sierra Leone's second largest city, and set about training the staff to give the best possible care to the desperately vulnerable babies who were admitted. But there was one problem he couldn't solve: electricity.
Babies need warmth, and that means electrically powered incubators, and they need oxygen, which means oxygen separators, and the nurses need light in order to work. However in Sierra Leone, there are power cuts almost daily. They can be a few minutes, they can be hours, or they can last days.
In 2017, Michael Liebreich heard about this problem and put together a group of friends and supporters to create Project Bo. Since then, the neonatal intensive care unit has had a solar system and batteries installed, and hundreds of babies’ lives have been saved due to a reliable electricity supply.
Eight years on, Michael visits Project Bo for the first time to see how the system is performing, meet the medical professionals working there, and find out if there's anything else that we can do to improve it.
