This article is useless. Virtually every building rejects heat outside using vapor-compression refrigeration.

#152The article mentions Riot Platforms, but the image seems to show Bitdeer Technologies
They're pretty much adjacent, but the orientation of the buildings is different:

Re: Satellites reveal heat leaking from largest US cryptocurrency mining center
#153I 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.
It’s 0%. Solar radiation is about 1.4kW per square meter.
We use a fraction of the sun’s total energy output each year, orders of magnitude more energy are in sunlight radiating onto the Earth than in the heat rejected from buildings with air conditioning.

Your math is completely wrong. We use ~20 TW, while solar radiation is ~500 PW and just the heating from global warming alone is 460TW (that is, how much heat is being accumulated as increased Earth temperature).
Well the math is correct, the methodology has obvious flaws some of which I pointed out. If you took all the energy that has been released by humanity burning things since the industrial revolution and dumped it into a closed system consisting of just the atmosphere, it would rise by about 1.5 C.
The discussion thread (and original question) you are participating in is about heat being rejected to the atmosphere through vapor-compression refrigeration or evaporative cooling, not CO2 or emissions from combustion. Reread the top level comment.
The amount of heat rejected to the atmosphere from electronic devices is negligible.

#155Climate pollution on this scale should be rated a crime against humanity.
Then what?
Re: Satellites reveal heat leaking from largest US cryptocurrency mining center
#156Technically any kind of datacenters, not just crypto, produces heat. Clouds, AI, banaking segment, etc.
Re: Satellites reveal heat leaking from largest US cryptocurrency mining center
#157"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.
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.

I was trying to work backwards to see what they were using as their ‘per house’ measure. Your usage is very low. Do you use electricity for water heating and cooking? If so, that’s impressive. We do, and charge a car.
Oh I see okay yeah. Used to have one electric car but it was on a separate meter with unlimited charging for $40/mo (just looked, now its $46). Added a few hundred to the charger install originally. We really don't do too much around the house. Three people. One TV running maybe two sometimes. Two desktops (well one is laptop with a dock). A random PC as a server. Everything electric (oven, range, water heater, filtr…
The car isn’t heavily used but averages about 6-8kWh per day.
With solar we are making a ton more power than we are using at the moment, it’s a sunny summer and we are managing to export something like 8x the power we are drawing from the grid.

#159New business idea: can they mine crypto in my kitchen, it's an old house and the heating is uneven. Also there are whole countries that run on central heating where hot water is pumped from a central power plant like facility to houses and apartments. Probably inefficient, but something they could do.
