Comment on Imagine not being able to shower, because AI slop generator machines need that water!
RunawayFixer@lemmy.world 1 day agoGenerating power with coal/nuclear/hydro uses water, and since the LLM data centers use power that would otherwise not have been generated, this is one of the ways that they use up water.
For cooling many (most?) data centers use evaporative cooling. That evaporated water could be captured again with a heat pump (reducing the wasted water + recuperating heat for other uses), but it’s Texas, so it wouldn’t surprise me one bit if the data centers have no intensive to be less wasteful.

I doubt those are constantly consuming large amounts of water. hydro just lets it through, and nuclear has chained closed loop systems, and they also let through some after the last loop
A hydro reservoir has much higher evaporation than if there was no reservoir. That’s usually a big part of the discussion when a downstream nation objects against another nation building a dam upstream from them.
Depending on the source, nuclear uses a bit more/a bit less water than coal. But they are in the same order of magnitude.

Ps: biomass power generation is a crime against nature.

oh, I wasn’t aware of that, makes sense.

why, what’s the problem with that?

That is super helpful, thank you.
