$Trump, Venezuela & The Future Of Clean Energy | Ep239: Michael Liebreich & Bryony Worthington Is the link between oil and geopolitics starting to diminish? Has climate consensus fractured just as clean energy hits escape velocity? And are batteries, not barrels, becoming the true source of power and security? In the first episode of Season 17 of Cleaning Up, Michael Liebreich and Bryony Worthington unpack a turbulent start to 2026. From shock geopolitical moves in the Americas and riots in the Middle East to the curious calm of a $60 oil price, they explore whether fossil fuels still move the world the way they once did. The conversation ranges from the collapse of climate multilateralism and Europe’s energy malaise to the unstoppable rise of electrification, batteries, and system-level clean energy solutions across China, India, Africa, and the “rest of the world.” 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, SDCL and Wärtsilä.

$Geothermal is Having a Moment, Can it Deliver? Ep179: Cindy Taff Is the key to clean energy the heat beneath our feet? Could advances in the fossil-fuel extraction industry hold the key to providing 24/7 clean power? And can a Texan CEO and former oil exec bring geothermal to the masses? This week on Cleaning Up, Bryony Worthington sits down with Cindy Taff, a 35-year veteran of Shell, where she was Vice President of Unconventional Drilling, leading a team of 350 people with a budget of over $1 billion. Since leaving Shell, Cindy has made a bold pivot to the world of geothermal energy, and is now CEO of Sage Geosystems, where she is using her expertise in drilling, project management, and subsurface engineering to try to crack next generation geothermal energy. Cindy shares her journey, from rising through the ranks at Shell to leading a startup on the cutting edge of the energy transition. She delves into the technical challenges of tapping into hot, dry rock geothermal resources, drilling at 20,000 feet below the Earths surface, the regulatory hurdles of using techniques like fracking or stim drilling, and the potential to to use geothermal wells as an energy storage solution. Cindy has a unique perspective on how the oil and gas industrys toolbox can be repurposed to drive the clean energy transition, and believes geothermal is poised to play a crucial role in powering a sustainable future. Will she be proved right?

$How To Build Clean Energy In The Global South — Ep196: Lucy Heintz The global south needs to build out vast amounts of clean energy, and requires hundreds of billions of dollars annually to do. And yet, only a fraction of the investment going into clean energy and the net-zero transition is flowing into those growth markets. So why are so few investing? Lucy Heintz is partner and head of energy infrastructure at Actis, whose most recent Energy Fund represents over $6 billion of investable capital. She is a driving force behind the small slice of investment which does address clean energy in growth markets. Lucy joins Cleaning Up to unpack Actis approach to investing in critical clean energy infrastructure projects across the Global South. From assembling renewable energy platforms to managing foreign exchange risks, Lucy shares the strategies that have historically allowed Actis to succeed in markets that many consider to be too risky. The Acronym Corner: • BII - British International Investment; the UKs development finance institution. https://www.bii.co.uk/en/ • LP - Limited Partner, the capital provider for fund • DFI - Development Finance Institution, e.g. BII • DISCO - A distribution company, in places like India and Pakistan. Responsible for distributing energy from producers to consumers. • DNO - Similar to a DISCO but UK focused, a company licensed to distribute electricity. • PPA - Power Purchase Agreement — A long term contract between an electricity producer and a customer, that guarantees electricity be bought and sold at a pre-negotiated price for the period of the agreement. • MIGA - The World Banks Multilateral Investment Guarantee Agency. Its mandate is to promote cross-border investment in developing countries by providing guarantees (political risk insurance and credit enhancement) to investors and lenders.
