Copying from another thread on this, but the focus on water use over electricity and emissions of datacenters does not make sense. It’s just helping datacenter by focusing on the wrong environmental issue because they are not a major contributor to water use. Agriculture, and animal agriculture specifically, are the super dominant water users. Even in water scarce places like the Colorado river archive.is/Gpibv Animal agriculture also pollutes ground water, and at a far higher rate and frequency. They create toxic algae blooms are from the runoff which means high nitrate levels in the local water level. Cancer rates are elevated nearby animal farms www.sciencedirect.com/…/S0013935126006286 Meanwhile electrical usage is delaying fossil fuel plant closure, leading to new ones, leading to backup generator use, etc. Datacenters are projected to go from 5% of electricity use to 15%. I keep seeing 5x the number of posts on the water usage than emissions. It’s letting datacenters get away with their super high emissions with so much less attention to it

    Worth noting that generating electricity is typically the second leading user of water behind agriculture. A 5 -> 15 percent bump will consume a lot more water unless new generation doesn’t spin a turbine with steam, just not at the data center itself.
