Imagine waking up after a night of heavy snow. In most cities, you’d expect the grind of snowplows, the sting of salt on sidewalks, and the frustration of icy roads.
But in Reykjavik, Iceland’s capital, people step out onto snow-free sidewalks—already melted by the Earth itself.
No diesel engines. No salt. No human labor. Just geothermal heat silently flowing beneath the streets, turning blizzards into puddles before they can pile up.

A Blizzard-Proof City Built on Fire and Ice
Reykjavik sits on one of the most volcanically active regions on Earth. While this geology has shaped Iceland’s history with eruptions and lava flows, it also provides something extraordinary: an endless source of geothermal energy.
Since the late 1990s, Reykjavik has tapped into that resource by running hot water pipes beneath roads, bike paths, and sidewalks. When snow falls, the warmth from volcanic heat melts it on contact, leaving surfaces clean and safe.
By today, over 50,000 square meters of surface area in the city is covered with geothermal heating grids—and the network is expanding every year.
How Does It Work? The Science Behind “Volcano Snowplows”
The system is deceptively simple:
- Hot water (heated deep underground by geothermal reservoirs) is pumped into insulated pipes.
- The pipes snake beneath the surface of sidewalks, roads, and even outdoor staircases.
- As snow or ice touches the surface, the geothermal warmth melts it immediately—before it can build up.
Unlike salt, which corrodes concrete and harms waterways, or plows, which burn diesel, this method is sustainable, silent, and endlessly renewable.
Why Don’t Other Countries Do This?
That’s the question most travelers ask after experiencing Reykjavik in winter.
The answer comes down to geography and infrastructure. Iceland is uniquely positioned on the Mid-Atlantic Ridge, giving it easy access to geothermal energy. More than 90% of Iceland’s homes are heated this way—so using geothermal for snow removal was a natural step.
For cities without volcanic heat, replicating this exact system would be costly. But hybrid systems—using waste heat from power plants, factories, or even district heating—are starting to appear in North America, Scandinavia, and Japan.
The Costs and Savings of a Snow-Free Winter
On paper, digging up streets to install geothermal pipes sounds expensive. And it is—millions of dollars for a single district expansion.
But Reykjavik offsets that cost in several ways:
- No salt trucks or plow fleets burning fuel every winter.
- Less road repair, since salt and snowplows often damage concrete and asphalt.
- Fewer accidents, saving money on healthcare and insurance.
- Boosted tourism, because visitors can comfortably walk the city—even during storms.
Over decades, the investment pays for itself—while improving quality of life.
If Your City Could Choose—Salt, Diesel, or Geothermal?
Pause for a moment.
If your hometown had the choice—would you rather fund fleets of plows and endless piles of salt, or install a renewable system that works forever?
Your answer probably depends on where you live—but it sparks a bigger conversation about how cities should invest in climate-ready infrastructure.
A Climate-Resilient Future Hidden Beneath the Streets
As winters become more unpredictable with climate change, cities face a paradox: some regions will see harsher snowstorms, others milder ones. Either way, infrastructure needs to adapt.
Reykjavik’s model shows how working with nature—not against it—can create solutions that are cleaner, cheaper, and smarter in the long run.
Instead of battling snow with chemicals and noise, Reykjavik lets Earth’s heat do the heavy lifting.
Beyond Snow: Other Uses for Underground Heat
Snow removal is only the beginning. Geothermal grids can also:
- Keep outdoor swimming pools warm year-round.
- Heat greenhouses to grow vegetables in arctic conditions.
- Power entire neighborhoods with renewable energy.
In fact, Iceland already grows bananas—yes, bananas—in geothermal greenhouses, proving that volcanic heat can do far more than melt ice.
The Global Potential: Could We All Have Snow-Free Cities Someday?
No, not every city can tap into volcanic reservoirs. But the principle—using renewable, waste, or excess heat to handle winter—is globally relevant.
- In Stockholm, engineers are capturing body heat from subway passengers to warm nearby offices.
- In Toronto, waste heat from underground data centers is being piped into apartments.
- In Minnesota, pilot programs use hot water from power plants to keep sidewalks ice-free.
Reykjavik may be leading, but the ripple effect is already spreading.
The Final Question: What If Every Winter City Did This?
Imagine a future where snowy cities don’t grind to a halt. No endless scraping of windshields. No salt-stained boots. No fleets of trucks roaring through the night.
Instead, warm streets quietly keep themselves clear—powered not by fossil fuels, but by renewable heat beneath our feet.
Would you embrace it? Or cling to plows and salt as “tradition”?
The answer may determine not just how we survive winter—but how cities prepare for the climate future.
