there are almost certainly heuristics you can use, but these are going to be heuristics the size of the national US grid, with physics similar to how water flows through pipes. Except these pipes are dynamic and significantly less restrictive.
Plus source generation is very sparse, CCG gas plants for example generally only run when peaking, and solar only works during the day, generally, and nuclear power runs 24/7 around the clock, so it’s not quite trivial to calculate. More than likely what the heuristic they’re using here is that they consume 43% more power as a corpo, and thusly, produce 43% more CO2.

That is assuming that those data centers are necessary. If the data center is doing something that is not really needed then it is in effect wasting power that could have been used for other purposes. (e.g. using surplus power to make steel or aluminium for instance)
While I do think that AI-tools can be increadibly useful, the current hype surrounding it very much looks like a bubble akin to the DotCom bubble to me. Companies left and right are jumping on the AI bandwagon for the sake of using the buzzword “AI” in their marketing speech.
I don’t consider that kind of use of datacenters to be necessary.

isn’t steel still primarily made through the coking process? Or is that transitioning to more efficient means, last i heard the barrier was efficient hydrogen generation.
Humanius@lemmy.world 4 months ago
You are correct, but that cooking process doesn’t have to be done with fossil fuels. Hydrogen (like you mentioned) is an alternative and you can create hydrogen using water and electricity.
In the NL we have a pretty polluting steel mill that is currently still coal fired. They are working on a transition plan where they adapt it to be gas fired instead, with the ability down the line to make it hydrogen fired when hydrogen production capacity is up to speed.

oh, you were talking about europe" I was thinking about america. Yeah i imagine it’s going to be a while here.
pulled from a US government thing, seems like most cleaner methods use refined iron. Although from some quick googling, it seems like this is a preparation method for iron ore, so maybe this is just a semantics thing here.
ok, and some statistics, it seem slike 30% of US production is using vertically integrated mills, or coal based production (presumably) Seems like they’re even cheaper, generally. Which is also a benefit.
So i guess overall, the steel industry is better than i expected.
