Data centers consume significant resources, often to the detriment of local communities. But while water use has been on the lips of those fighting back against data center deployments, the sheer scale of their impact wasn't entirely clear until recently.

Many new U.S. data centers are being built on drought-prone land, and their cooling systems, which seem to consume gargantuan quantities of water, only represent a small portion of their total water usage by 2050. So, what makes up this overall figure for water usage? Cooling, of course, plays a part, but ongoing energy demands and chip fabrication also make up a larger part of the story.
