Closing the Gap with Gwen Holdmann

Norway is determined to move away from coal and other fossil fuels entirely, but the town of Longyearbyen in the Arctic outpost of Svalbard is literally built around coal and has identified strongly as a coal town for more than 100 years. This year, the last coal mine in Longyearbyen shut down — not because they ran out of coal, but because the country is deeply committed to trying something else, even if they haven't totally figured out what that something else is yet.

On this podcast, we spend a lot of time talking about electricity — how to generate it, store it, and use less of it. But the truth is, the bigger share of our energy use often goes to heating and cooling — the invisible comfort systems that keep us alive in the places we choose to live.
Humans are unusual that way. Most species adapt to their environment. We do the opposite — we adapt the environment to suit us. It's how we survive in deserts and tundra, in glass towers and remote villages.
Today on the show, we're talking about passive cooling. We bring you three stories of designs that take advantage of natural temperature differences instead of using up a bunch of energy just to make something cold.

Waste-to-energy systems kill two birds with one stone: they deal with garbage and produce power at the same time. Copenhill in Denmark has been called the coolest power plant in the world, and it's hard to argue with that. It's a place where you can ski down the roof, climb up the side, and then grab coffee under the smokestack — all while the building generates heat and energy for the city.  At least one Alaskan community thinks Copenhagen might hold the answer for its energy and waste problems — and that's exactly where this episode takes us.

The multi-million dollar fighter jets that roar over the local tennis court where I coach the high school team is a daily reminder that Fairbanks is home to one of the most strategically important Air Force bases in the world. And now, Eielson Air Force Base is about to make history on a very different front — testing a first-of-its-kind nuclear microreactor.

Back in 2019, Congress directed the Department of Defense to find a site and pilot a small nuclear reactor to enhance energy resilience at military installations. That site is Eielson Air Force Base near Fairbanks, Alaska. Recently the Air Force named a developer for the reactor, so we're revisiting the story we told back in Episode 5. In future episodes you'll hear directly from the key people moving the project forward—both the technical lead for the Air Force and the senior commander guiding its integration on the ground. For now, we're sharing episode 5 with you as a refresher.
