Bet ya Trump will make this illegal: it makes too much sense

Data centres are energy hungry but what if we could use their waste heat to heat our homes?

That's exactly what happens in places like Finland: Cities are tapping the vast amounts of waste heat generated by data centres, and feeding it into district-heating networks.

America is always about building in the cheapest way possible. That's why these data centers look nondescript and are in more suburban/rural areas where land is cheaper.

You get that in a lot of developed areas. This takes planning and the ability of navigating an antiquated permitting process. In a lot of instances it’s much easier to put these things in rural or poor communities where opposition is less organized than developed communities with the resources to oppose them.

Thu Dec 4, 2025, 09:54 PM
7 hrs ago

... that is seemingly better suited to adaptation to distribute waste heat from data centers

This type of "district heating" infrastructure is more common in countries that employ more geothermal energy. It is apparently a less common type of heating system here.

Perhaps it is time places in the U.S. that are in the most need of efficient heating start exploring such centralized options. Seems it would be feasible in many high-density areas (e.g., upgrades of old systems and implementation of new systems in high-density areas -- e.g., much of the corridor from Fairfield, CT, to NYC, to Hoboken, the Palisades, and Union City...)

Question (Yeah, I know, problematic construction):
"Where in the United States is the infrastructure for district heating through underground pipes, similar to what they have in Finland, used."

Answer from Gemini (take with whatever grains of salt you apply to any AI summary)

Yes, the United States has a long-standing history of district heating infrastructure, particularly in the form of downtown steam districts in cities like New York, Boston, and Philadelphia. While not as extensive as Finland's modern systems, these steam networks have been in operation since the late 19th century, heating numerous downtown buildings and campuses. Some of these systems have been updated from older steam-based technology, while new, more advanced systems are also being implemented in various locations, though they are not as common as in Europe.

New York City: Has one of the oldest and largest steam districts in the US, with underground pipes distributing steam to a large portion of Manhattan.

Boston and Philadelphia: Also have active steam districts in their downtown areas, using a system that heats buildings and campuses.

Downtown Dayton, Ohio: Historically had a large steam heating system that powered downtown buildings and industries, with some lines still in place today.

Newer systems: While less common than in Europe, modern district heating systems using hot water instead of steam are being implemented in various locations for new developments or upgrades to existing infrastructure. These systems can use a variety of energy sources, including geothermal, waste heat from data centers, and other renewable sources.

For the sort of "district heating" that could make use of the waste heat to make sense, you'd need densely populated cold places like Minneapolis-St. Paul, Milwaukee, WI, Cleveland, OH, Marquette, MI, Buffalo, NY, Boston, MA (already has some district heating infrastructure), or even places like Grand Forks, ND.

these data centers still need power to run. So expanding data centers will still need more and more "Bountiful Clean Coal" to run. We're just tapping their waste with this, and I'm sure they can figure out a way to profit from it.

Applies to the “waste” their creepy fellow travelers the “data as oil” creeps mine as well. That metaphor is so daft given climate change.

If those data creeps could use the “waste” towards something the data generator (is that what one is?) supported without qualms, it would be one thing. But transactionalism that myopically destroys democracy, the environment and civil rights never has any legs.
Unless you are resigned to an eternal hellscape which I am not.

...with much more use of geothermal energy and the infrastructure to support it. The U.S. not so much.

But I bet some version of this does happen in many blue--and even red--states.

We just tend to use electricity for heating and cooling, so finding ways to convert the waste heat into electricity is the challenge here.

And, this is not actually a reliably red versus blue issue as we would like to think:

South Dakota--which hasn't voted for a Democrat in a presidential election since 1964--leads the nation in renewable energy production, with 92% of its electricity coming from renewable sources as of 2024.
https://www.sdnewswatch.org/fact-brief-south-dakota-wind-solar-clean-energy-production/#:~:text=South%20Dakota%20is%20ranked%20No,and%20Kansas%20third%20(74%25).

Note that "Iowa is second (83%) and Kansas third (74%)".

When you drive across Kansas to get to blue Colorado it is actually striking how many wind turbines there are between the billboards for Jesus and anti-abortion screeds in that very red state.

Will the Maniacal Orange Menace hate it? Yes. But I still don't think that will stop progress--because it really hasn't so far....

In a lot of Europe there are "steam utilities." When they build your house they tap into the main city steam pipe to connect it to the radiators in your home, then when you want heat you just turn a valve. It's way cheaper than installing a furnace and it works.

Outside of the big cities they don't have this at all in the US, and even in the big cities this might not be for everyone. For instance, CenTrio sells steam in Seattle but they only sell it in part of the city.

I wonder...is there a way to recover the heat pulled out of data centers and use it to generate electricity? That would work better than trying to sell the heat directly.

just profit and/or ideology.

When countries that are the size of our states do great things for their people, that doesn't make us look bad, but just makes the point of how small countries can innovate as well as afford nationwide change faster.

One thing that does make us look bad is that we have 90+ percent of the nation's wealth concentrated at the top, and the highest poverty level out of 38 OECD countries. Another thing that makes us look bad, when you look behind the drama curtains -- it's the tech and Koch oligarch networks that are privatizing the country into a plantation.

Their corporate messaging says, "nothing personal, just business" as the collateral damage turns into national human wreckage.
