That's crazy interesting, I've heard of district heating in places like new York, but I've never really thought of the same for cooling.
What's abit confusing though is ACs really just move heat from the cold end to a hot end. Normal ACs just blow out and heat the outside air abit, which is part of the problem district cooling is trying to solve, but if all they did was release the heat into the air, it wouldn't be any better.
Anyone got any idea what they do with the heat energy? My first thought was they could be using geothermal from dirt far below the city that's at like 50°F always, as some houses do, but I feel like they would be talking about "using the Earth's energy to cool our cities" if that was the case
