"leaking" is the wrong word here - it implies some sort of inefficiency, process which is not working as well as it needs to. Leaky bucket, leaky faucet...

That's not the case here, that center is __dumping__ heat into environment - it is by design, all that electricity is being converted into the heat. By design, it's enormous electric heater.

I wonder if there's enough heat being produced for it to act as a district heating plant.
hephaes7us•21m ago
There absolutely is, but of course it's nonzero cost to capture.
timeon•1h ago
Not sure what your point is. With POW inefficiency is by design.
edoceo•56m ago
You got the point. It's "by design" - you've both said it.

a home can leak heat to the environment because of bad insulation. a datacenter doesn't leak heat because leaking is normatively bad.

Technically it is inefficiency. The electricity should be doing computer things. Heat is wasted electricity. Just there's not much the data centre could do about it.
geoffschmidt•11m ago
Heat is not by itself waste. It's what electricity turns into after it's done doing computer things. Efficiency is a separate question - how many computer things you got done per unit electricity turned into heat.

There’s a minimum level of energy consumption (and thus heat) that has to be produced by computation, just because of physics. However, modern computers generate billions of times more heat than this minimum level.

So I don't have any context for this. The article says it uses as much power as 300,000 homes. Is that a little? Is that a lot? How much does one steel foundry use?

Edit: One steel foundry uses about 3,000 more than that, according to my napkin math

sowbug•1h ago
You can multiply your own power bill by 300,000 if money is a more relatable unit.

Home energy usage is knocked down people that don't that don't do anything at home and where almost their energy use is externalized (at places that make the goods they use, or other places where they spend most of their their waking hours).

So it's a useful figure if you want to make a shocking headline. "Uses as much power as infinity of something that uses no power!"

driggs•39m ago
Have you considered that it's used as a unit to represent capacity of our power grid?

As in, we have now have the energy capacity for 300,000 fewer homes given this operating data center.

So not only is it a relatable unit, but it's an incredibly meaningful unit for those who care about ensuring that energy availability actually support something of value (families) rather than something wasteful (crypto mining).

3,000x would be 2.1 terawatts. That would require about 100 Three Gorges Dam, currently the largest generating station in the world, to power one foundry. Or about 2,100 nuclear power plants of typical size. I think your napkin math might be a bit off.

This was previously the location of an Alcoa aluminum smelter which used something around 1000+ MW. And that's why the crypto farm is there -- it already had sufficient electrical capacity to the site.

Folks should be happy since the crypto operation is using far less power and dumping less heat into the environment that the industrial operation that was previously there, but datacenters seem to be a trendy thing complain about at the moment so here we are.

I do get utility out of aluminium.
troglo-byte•25m ago
A cryptominer is a "datacenter" in the same way that a chop shop is an automotive parts supplier.
dajt•5m ago
Where is the upside here? An alu plant probably provided more jobs and produced something of actual utility. This is burning power for no benefit to society.

It's burning less power than before, but it's not producing anything of value.

The world cannot reasonbly run without alu, it got along better without crypto currencies.

drivingmenuts•5m ago
How many people did the smelter employ vs how many people do the bitcoin miners employ?

The smelter was providing jobs that fed money into the local economy. I'm sure much less money is coming out of the mining operation.

I always wondered if anybody has calculated how much of our global heating could be attributed, if any at all, to every electronic device, server, and engine outputting heat as a byproduct.

funny how somehow similar this image looks to that of a pc motherboard.
