Amazon Says Its Data Centers Use 2.5B Gallons of Water
Amazon drops giant water number and the internet instantly starts fighting over the math
TLDR: Amazon says its data centers used 2.5 billion gallons of water last year, a number landing in the middle of fights over new server farms and local water worries. Online, people split between “that sounds huge” and “golf courses use more,” with plenty of snark about terrible popups and sloppy context.
Amazon just revealed that its data centers used 2.5 billion gallons of water worldwide last year, and the comment section wasted absolutely no time turning that corporate disclosure into a full-blown numbers brawl. The company says the figure shows it cools its giant server buildings efficiently, while critics say the bigger issue is still transparency: where exactly is that water being used, and what does it mean for local communities already nervous about new data centers popping up nearby?
But online, the real show was the reaction. One camp basically shrugged and said, wait, that’s it? Commenters rushed in with comparisons meant to deflate the panic: one person noted that US golf courses use about 2 billion gallons a day, while another compared Amazon’s annual total to just a few days of London’s water use. A third argued that if this is the largest cloud company on Earth, the number sounds surprisingly small.
Then came the chaos of people trying to do back-of-the-envelope math in public, correcting each other in real time, and grumbling that the article’s paywall and popup storm were harder to survive than the water stat itself. The funniest line of the thread may have been a user saying the popups almost gave them epilepsy before they could even read the piece. So yes, Amazon wanted to talk efficiency. The internet heard “2.5 billion gallons” and responded with skepticism, calculator warfare, and a side quest about annoying news sites.
