Waste heat from data centers can boost air temperatures in downwind neighborhoods by as much as 4 degrees Fahrenheit, researchers at Arizona State University report in a new study conducted in the Phoenix metro area, the hottest in the U.S.
They are wasteful on purpose. they could have closed circuit cooling systems where they condense the water from the vapor and reuse it. But they are a giant middle finger to all of us.
Pretty sure most modern data centers are using closed loop cooling or refrigeration. Not evaporative cooling.
You can’t condense the water either that would defeat the point of evaporating it in the first place. Closed loop liquid cooling does not involve boiling or evaporation. You are just pumping a liquid around a circuit. It’s not just water either it’s more like a car antifreeze.
Got any info to back that up? Here’s a screenshot from page 39 of the US Data Center Energy Usage Report, which shows the use of closed loop systems (which they call dry cooling) as one of the smallest percentages of cooling types used. Pretty sure you’ve got it completely backwards on the types of cooling used, and I know for a fact the massive Amazon data center out in Oregon uses evaporative, because you can’t drink the water there as a result.
The laws of thermodynamics? Can’t create or destroy energy and overall entropy increases over time. A closed loop (or any cooling system) just moves heat away from the hot thing. So yes, they can be used as much as any other cooling system but it won’t stop the issue of “generating lots of heat”. That heat still needs to go somewhere. Dumping it into the atmosphere might be the best option if there’s nothing in the area that needs heat. Should probably build them next to steel plants or something like that. Then a closed loop would be better.
The guy you are replying to doesn’t actually know jack about data centers. Plenty do use closed loop cooling which doesn’t involve evaporating water. It’s only a minority that use evaporative cooling. Power stations are more likely to use evaporative cooling (hence big towers with steam clouds) than datacenters are. They also use far more cooling water than datacenters do. Both pale in comparison to agriculture and other uses.

Water is cheaper to waste than electricity unfortunately.

Just a talking point in an investors report. The more I read on these centers the more I am convinced they are not built to work.
