• Mapping the Next Energy Shock with The Economist's Vijay Vaitheeswaran
    May 14 2026

    The aftershocks of the Iran war are reshaping energy markets, investment decisions, and climate politics in very different ways around the world.


    David, Sara, and Ed sat down with Vijay Vitheeswaran, Global Energy and Climate Innovation Editor at The Economist and 2025 Energy Writer of the Year, to discuss the shock rippling through energy markets since the war in Iran began.


    On one side are forces accelerating the energy transition like electrification, EV adoption, solar deployment, and rapidly scaling clean tech. On the other are forces pushing toward deeper fossil fuel lock in: energy security fears, coal expansion, oil investment surges, and persistent fossil fuel subsidies. Which force is actually winning?


    The conversation covered a lot of ground — from samosa vendors in Delhi packing up because cooking fuel tripled in price, to what a potential OPEC collapse could mean for the oil sands.


    This show's a great listen, especially if you're trying to make sense of a world where the energy transition and fossil fuel lock-in are happening simultaneously.

  • The Nuclear Option: A Canadian Reality Check with Jason Donev
    Apr 30 2026

    Nuclear is having a global moment. But the story in Canada is a lot more complicated.


    David, Sara, and Ed sat down with Prof. Jason Donev of the University of Calgary for a full, unsparing look at where nuclear fits in a rapidly growing and electrifying Canadian grid.

    Jason is one of the clearest thinkers on energy systems in the country. He's also someone who started out opposed to nuclear and changed his mind.

    We set this episode up to tackle two questions. First, what is the case for new nuclear right now, given rising electricity demand from electrification, industry, and AI. And second, why Canada, despite decades of experience, has struggled to build new projects beyond Ontario and New Brunswick.

    A few things you'll hear about:

    • Canada had a nuclear accident in 1952. Jimmy Carter helped clean it up.
    • “Small” modular reactors can be up to 300 megawatts. A CANDU is closer to 700. “Small” is a relative term.
    • Darlington’s BWRX-300 is a closely watched test case for Western SMRs. Will costs fall with follow-on units, or will nuclear repeat its Achilles heel and get more expensive?

    It turned into a lively and wide-ranging conversation on costs, timelines, small modular reactors, and the deeper issue that keeps coming up with nuclear. The physics may be solved, but the politics and institutions are not.


    About Our Guest:
    Prof. Jason Donev is a tenured professor teaching Energy Science and Physics at the University of Calgary. He leads EnergyEducation.ca, the world’s largest and most widely used energy resource for adults.

  • The Hosts in the Hot Seat: Turning the Tables on Ed and Sara
    Apr 16 2026

    EvC Superfan and fellow energy nerd Robert Tremblay turns the tables on Sara and Ed — asking the questions the podcast usually doesn't: how EvC started, the energy transition over the 7 seasons of the show, what's changed, and whether any of it is working.


    They get into their backgrounds, the EvC origin story (are the rumours about Danielle Smith true?), how the show has evolved, and what they actually think about Canada's climate trajectory. Plus a rapid-fire round... well, at least as rapid-fire as EvC gets.

  • From Straits to Stoves and Tankers to Tables: Iran, Oil and Climate Trade-Offs in a Crisis
    Mar 19 2026

    The Iran war and the near-closure of the Strait of Hormuz have triggered a major shock to global oil and LNG markets.

    Roughly 20 million barrels of oil per day normally move through Hormuz. The IEA says nearly all of that has been disrupted.

    Oil and gas prices have surged sharply; and the disruption extends well beyond oil as Qatari LNG exports have been largely severed. Asia is especially exposed, since most Gulf energy exports flow there.

    This isn’t just an oil story. It’s a “can people cook dinner” story, a reminder that geopolitics gets real once it enters the kitchen.

    In this episode, David, Sara, and Ed unpack what this shock means for global energy markets, the climate, and the pace of the energy transition.

  • The Hidden Power Bill of Artificial Intelligence with MIT's Vijay Gadepally
    Mar 5 2026

    Vijay Gadepally joins Ed and Sara to break down the real energy footprint of AI—and why most people (and companies) are getting it wrong.

    They discuss:

    • How "agentic" AI systems use an order of magnitude more energy than ChatGPT.
    • Whether efficiency gains can keep pace with exploding usage (spoiler: not yet).
    • The one simple change that could cut AI energy use by 80%.

    Vijay is Senior Scientist at the MIT Lincoln Laboratory Supercomputing Center and Co-Founder of Bay Compute and Radium Cloud. He studies what's actually happening under the hood of AI systems—and has the data to back it up. If you've been wondering whether AI is derailing the clean energy transition, or whether smarter software design could keep energy use in check, this is the conversation you need to hear.

  • Understanding China's Energy Transition: Experts Weigh In | Andrew Light, Jeremy Wallace, Christina Pan, and Hong Li
    Feb 19 2026

    This episode is different. We're tackling China's energy transition, and instead of David, Sara, and Ed just talking about it, they went out and interviewed different experts on the subject.


    Why China? Because it's arguably the most important energy story on the planet right now. China is the world's largest emitter. It's also the world's largest investor in clean energy. It manufactures the lion's share of solar panels, batteries, and now electric vehicles in the world.


    Functionally, what happens there determines whether the world has any real shot at meeting long-term climate targets.


    David spoke with Andrew Light, distinguished professor at George Mason University and former Senior Climate Official in the Biden administration.


    Sara talked with Jeremy Wallace, professor of China Studies at John Hopkins and Christina Pan, a PhD candidate at Cornell researching renewable energy in China.


    And Ed interviewed Hong Li, a professor at the Institute of Physics at the Chinese Academy of Sciences, and an expert on battery chemistry.


    Three different perspectives followed by David, Sara, and Ed trying to make sense of it all.
