Realizing the water risk in New Mexico, Meta, formerly known as Facebook, ran a pilot program on its Los Lunas data center to reduce relative humidity from 20% to 13%, lowering water consumption. It has since implemented this in all of its center. But Meta’s overall water consumption is still rising steadily, with one fifth of that water last year coming from areas deemed to have “water stress,” according to its website. It does actively restore water and set a goal last year to restore more water than it consumes by 2030, starting in the west.
Microsoft has also set a goal to be “water positive” by 2030. Â”The good news is we’ve been investing for years in ongoing innovation in this space so that fundamentally we can recycle almost all of the water we use in our data centers,” said Brad Smith, president of Microsoft. “In places where it rains, like the Pacific Northwest where we’re headquartered in Seattle, we collect rain from the roof. In places where it doesn’t rain like Arizona, we develop condensation techniques.”
