  • Using more of the grid we’ve already built
    Apr 1 2026

    The US power grid runs at about 50% capacity on average — built for its worst day, underutilized every other day. As demand surges from data centers and electrification, utilities are racing to build more infrastructure. But Ian Magruder, who heads the new industry-backed Utilize Coalition, argues there's a cheaper, faster path: better use what we've already built — it will enable faster growth and bring down ratepayer bills, potentially by billions.

  • Should we block some sunlight to cool the planet?
    Mar 27 2026

    In this episode, Dakota Gruener of Reflective walks me through her organization's new project, which maps the gaps in our scientific understanding of stratospheric aerosol injection — currently the leading candidate for directly cooling the planet. We get into what we don't know (including a factor-of-two disagreement on basic aerosol physics), who's already doing this without oversight, and the unsettling governance question of who controls the Earth's thermostat once humanity has grabbed it.

  • For data centers, a little flexibility goes a long way
    Mar 25 2026

    The explosive energy demand from data centers is breaking our grid, pushing desperate developers to build their own on-site gas plants just to get online. To figure out how we avoid locking in decades of new fossil fuels, I’m joined by Camus CEO Astrid Atkinson and Princeton’s Jesse Jenkins to break down their proposed alternative. We dig into how adopting flexible grid interconnections and clean, battery-backed “power parks” can meet this massive load growth without abandoning our decarbonization goals.
