Cleaning Up: Leadership in an Age of Climate Change

Through nearly five years of war, Ukraine has been forced to adapt on the fly as attacks target its energy infrastructure, and the country has been ingenious in finding new ways to generate, distribute and protect power. Its experience has exposed vulnerabilities in the rest of Europe’s energy systems, and raises the difficult question of how well prepared our own energy systems are for disruption.
In the fifth episode of our Deep Dive Ukraine series, Michael Liebreich is joined by Ben Parsons, Partner at Oaklin, who travelled with Michael on his recent delegation to Kyiv. Together, they reflect on what they saw and heard in Ukraine, from the extraordinary efforts to keep the electricity system running under attack to how Ukraine has been forced to adapt its energy system at extraordinary speed.
From standardising equipment and making repairs easier to scaling up smaller, more distributed energy assets and better-protected infrastructure, they explore how Ukraine is building resilience in the face of relentless pressure. They also consider what the UK and other countries can learn from this experience, and why resilience needs to be built into energy systems now, rather than waiting for a crisis.
Topics covered in this episode:
What Michael and Ben learned from their visit to Ukraine
Keeping the energy system running under sustained attack
Rebuilding and repairing critical infrastructure during wartime
The case for decentralised and flexible energy generation
Why standardised equipment and spare parts matter
What the UK and Europe can learn from Ukraine’s experience
Building resilience into future energy investment
The role of international support, expertise and investment in Ukraine’s reconstruction

Despite the Trump administration's efforts to roll back clean energy subsidies and climate policies, America's energy transition is proving more resilient than many expected. Solar and battery deployment continues, nuclear power is attracting billions in private investment, and demand for electricity is surging. But after a historic set of midterms where does the US go from here?
In this episode of Cleaning Up, host Bryony Worthington speaks to David Victor, Professor of Innovation and Public Policy at the University of California, San Diego, about the political and economic forces shaping America's energy future.
They discuss what the US midterm elections mean for energy and climate policy, why renewable energy is continuing to grow in Republican states, and how the explosion in data centre demand is transforming the electricity industry. They also explore the backlash against AI infrastructure, the prospects for a new generation of nuclear reactors, the future of electric vehicles and America's increasingly complicated relationship with China.
Victor argues that the fundamentals of the energy transition are stronger than the political headlines suggest. But with an unreliable federal government, and public resistance to new infrastructure, the challenge now is turning technological progress into something that works for everyone.
Topics discussed in this episode:
The US Midterm Elections and the Energy Agenda
The Future of Clean Energy Under Trump
Data Centres, Electricity Demand and the Grid
The Politics of Building New Infrastructure
The Damage to American Government Institutions
Nuclear Power and the Role of Private Investment
Why Climate Change Is Struggling to Gain Political Attention
The Future of Electric Vehicles
Electric Aviation and New Technologies
China, Trade Restrictions and the EV Industry

Mexico’s energy future is closely tied to its neighbour to the north. It imports much of its natural gas from the US, but could it soon be exporting clean electricity, or even data, in return? With electricity demand surging, Mexico is preparing for a major expansion of its power system, with 30GW of new generation planned by 2030 and more than $40bn in potential investment.
This week on Cleaning Up, Bryony Worthington speaks to Alberto Estefan, Managing Director of Energy Infrastructure at Actis, about the scale of Mexico’s renewables opportunity. They discuss the country’s growing electricity needs, its dependence on US natural gas, and the investment needed to transform its power system. They also explore the challenges of grid expansion, the role of batteries and whether Mexico could become an energy and data exporter to the US.
Topics covered in this episode:
Mexico’s renewables boom
Latin America’s investment opportunity
The US-Mexico energy relationship
The economics of solar and batteries
Mexico’s new investment framework
Does natural gas still have a role?
Mexico as a potential data and energy exporter
The risks of delivering the energy transition
El Niño and Latin America’s energy security

The grid is one of the most important assets in any functioning energy system, transmitting electricity from where it's generated to where it's needed. In Ukraine, that challenge is enormous.
The country is very big, 1,300 kilometers from east to west, almost the distance from London to Rome. And the system is under constant attack from Russia, which targets the grid with everything from tiny drones to ballistic missiles.
In this fourth episode of our Ukraine Deep Dive, we're featuring two separate conversations with guests intimately familiar with the operations of that grid: Vitalii Zaichenko, the current chair and CEO of Ukrenergo, Ukraine's national grid operator, and Volodymyr Kudrytskyi, the former CEO of Ukrenergo from 2020 to 2024, and now co-founder of Negen.
Michael asks each of them how you protect a grid under constant attack. They also talk about the remarkable story of how Ukraine disconnected itself from the Russian grid and connected itself to the European grid in just three weeks at the beginning of the full-scale invasion, how to build more resilient energy systems, and why there's so much political scandal around the management of Ukrenergo and whether Ukraine could be better prepared for winter.
Topics covered in this episode:
Russia’s attacks on Ukraine’s electricity grid
Protecting substations from missiles and drones
Ukraine’s rapid synchronisation with Europe
The shift towards decentralised power generation
Batteries balancing nuclear, solar and wind
Financing and insuring energy projects in Ukraine
The political controversy surrounding Ukrenergo’s leadership
Lessons for global energy system resilience

Indonesia is facing a defining question: can it continue to grow its economy while making the shift towards a greener future? In this episode of Cleaning Up, guest host Marie Cheong speaks with Sandiaga Uno, chair of Mutuagung Lestari International and former Deputy Governor of Jakarta and Minister of Tourism, about Indonesia’s potential to become a major player in the green economy, and why the country’s natural resources, growing energy needs and entrepreneurial ecosystem could create significant opportunities for climate solutions and investment.
They explore whether green investing could be the next major growth opportunity, why the economics need to stack up, and how moving beyond the idea of a “green premium” towards “green discounts” could make sustainable business models more competitive. From the challenge of moving away from coal while meeting rising energy demand, to the potential of carbon credits and nature-based solutions, the conversation looks at what it will take to turn Indonesia’s green potential into real economic and environmental value and what investors should consider before taking the plunge.
Topics covered in this episode:
Indonesia’s green growth potential
Green investing’s next growth cycle
Green premiums vs. green discounts
Politics and the energy transition
Moving beyond coal
Carbon credits and nature-based solutions
Turning green potential into profits
What green investors should look for
