Decouple

Dr. Chris Keefer

There are technologies that decouple human well-being from its ecological impacts. There are politics that enable these technologies. Join me as I interview world experts to uncover hope in this time of planetary crisis.

  1. To Bomb or Not to Bomb

    To Bomb or Not to Bomb

    Professor Alex Wellerstein returns from the set of WIRED (watch his excellent appearance here) to help me understand the origins of Middle Eastern nuclear programs and where they stand today. From France’s covert assistance to Israel’s bomb program in the 1960s to the mysterious Vela incident over the South Atlantic, Wellerstein shows how nuclear weapons spread through unofficial networks of scientists, spies, and opportunistic allies. We explore Iran’s strategic nuclear hedging, Israel’s policy of deliberate ambiguity, and the disturbing possibility that recent attacks on Iran’s uranium enrichment facilities may force the country’s hand toward weaponization.

  2. Rare Earth Emergency

    Rare Earth Emergency

    This week, we talk about rare earth metals. What are they, where do they come from, and how are they redefining global power? I’m joined by David Abraham, a natural resource strategist who saw the future of rare earths in 2010 while working in Japan's Ministry of Economy, Trade and Industry. When China cut off rare earth exports over a territorial dispute, Abraham realized these obscure elements, sprinkled into our steel, the magnets in our speakers, the phosphors in our screens, held more geopolitical power than oil ever could. The warnings in his book, “The Elements of Power,” now written 10 years ago, feel like reading a prophecy. Half the periodic table now flows through your iPhone, and China controls 90% of the world's refining capacity for these critical materials. As trade wars escalate and great power competition returns, the country that controls rare earths may control the Earth itself.

    Battery Power

    This week, we talk about the rise of the global battery industry: its history, key players, raw material struggles, and how China came to dominate it. To do so, I’m joined by Henry Sanderson, author of "Volt Rush: The Winners and Losers in the Race to Go Green." We trace the story of electrification from Volta’s early experiments to the supply chains that now shape global power. Sanderson brings decades of reporting to a narrative that reveals China’s industrial strategy, the entrepreneurs behind battery giants, and the troubling realities of mining cobalt, nickel, and lithium. Together, we examine how technology, geopolitics, massive wealth, and environmental trade-offs define the future of clean energy.

    The Export Expert

    This week, we talk about Russian nuclear exports. Michael Seely, host of AtomicBlender, joins me to discuss the rise of Rosatom: Russia’s nuclear energy behemoth that now builds nearly half of the world’s new reactors. We trace its formation after the Soviet collapse, its grip on the nuclear fuel market, and its unmatched “turnkey” model for newcomer nations. Rosatom’s nuclear exports are more than just a commercial endeavour—they can reshape global influence for decades. Michael's videos on Canada, Russia, and Ukraine.

    #289 - Breaking the Ice

    This week, we travel to the edge of the map with Aleksandr Surtcev, an engineer who has crewed Russian nuclear icebreakers along the Northern Sea Route. We explore how Russia’s Arctic fleet keeps this strategic corridor open, why floating nuclear plants are powering remote communities and mines, and what life looks like in a place where polar bears trail ships for fish and resupply markets pop up on the ice. Beneath the stories lies a deeper discussion of geopolitics, engineering, and the hard logistics of operating in one of the most unforgiving regions on Earth.

  6. The State of the Atom (2025)

    The State of the Atom (2025)

    This week, Mark Nelson joins us to deliver his second annual “State of the Atom” address. The nuclear power landscape has transformed in the last two years. Russia continues its nuclear export dominance while the West at last awakens from its stupor, driven by an unexpected force: artificial intelligence's insatiable appetite for baseload power. From Amazon's billion-dollar Susquehanna deal to Three Mile Island's resurrection, Big Tech is discovering what nuclear advocates have long known: that when you need reliable electricity around the clock, few other generation sources compare. Nelson maps the new nuclear battlefield where Chinese reactors scale up to 1,700 megawatts, European phase-outs crumble, and Western teams scramble to assemble the talent and capital needed to compete.

  7. Sun, Silicon, and Xinjiang

    Sun, Silicon, and Xinjiang

    This week, we talk solar power—a long overdue topic on Decouple. In the past, guests have often been critical of the value of renewables on grids without extensive storage, and of the quality of jobs that politicians often claim when justifying renewables programs. Today, however, we drop preconceptions and get to the nuts and bolts. My guest is Seaver Wang, director of the Climate and Energy Research Program at The Breakthrough Institute. Despite is imperfections, the solar power has a remarkable story, from its technological origins, to its dramatic cost reductions in the last decade, to the sheer scale of new capacity being added in places like China. We cover these topics and more in this episode: the Solar Masterclass. Watch now on YouTube. We talk about Historical roots and evolution of solar technology Impact of the German Energiewende and feed-in tariffs China's rise to dominance in solar manufacturing Energy-intensive production processes of polysilicon Controversy over Uyghur forced labor in Xinjiang Solar’s lifecycle emissions and environmental impacts Dramatic cost reductions and economies of scale Limitations and misconceptions in distributed solar Future integration with battery storage Role of geopolitical and ethical issues in solar supply chains

  8. Small Reactor, Big Price

    2 JUIL.

    Small Reactor, Big Price

    We have an unusual episode today. One, because of its length (1 hour 40 minutes), and two, because I’m the guest. Joined by Aidan Morrison as acting host, I talk about a topic of intense interest to me: the Darlington SMR project in Ontario, Canada. I’ve been critical of this SMR project, which recently received its final investment decision, by calling for a pivot to CANDU reactors at the site. I use this episode to break down all my reasons for being critical, and to concede ground to this bold SMR project where earned. This is not the first place I’ve shared my reasoning (media interview here, LinkedIn post there), but it is the most in-depth. If you have time to listen to the full thing, I promise you will leave quite knowledgeable about the ambitious and capable Ontario nuclear sector, which I’ve studied and engaged with for years. Prompting this episode was the OPG’s final investment decision on the SMR and the revelation of its eye-watering cost estimates. I break down the $4.5 billion price tag for the first unit, the expected learning that will take place, and share why this represents not just a technical and economic challenge, but a strategic mistake that could undermine Canada’s competitive advantage in nuclear power. From the massive excavation challenges of burying a reactor ten stories underground to the national security risks of abandoning proven CANDU technology for American designs, I hope to share some of the hard truths behind the SMR hype.
