The West's biggest online shopping mall comes clean about its datacenter water usage
Amazon says its datacenters used about 2.5 billion gallons of water last year, but claims that's far less than rival hyperscalers and that it remains on track to become "water positive" by 2030.In a blog post, the digital tat bazaar and cloud computing biz says the 2.5 billion gallon figure covers its entire global datacenter footprint for 2025. It downplayed the number by comparing it to the volume of water Americans - a country of 350 million people - used on lawns and gardens over the same period.Amazon disclosed water usage of 0.12 liters per kilowatt-hour (L/kWh) at its data facilities, and claimed Microsoft used 0.27 L/kWh during 2025, while Meta's consumption stood at 0.19 L/kWh in 2024 and Google was the thirstiest at 1.15 L/kWh during the same year.
The Register has asked Microsoft, Meta and Google to comment.The water usage, we're told, is 75 percent of the way to Amazon's goal - announced in 2022 - of being "water positive" by 2030. It means facilities return more water to the environment than they consume, via measures including rainwater capture or other treating waste water for reuse.The figures come amid growing pushback against datacenter construction in the US. A recent Ipsos survey found most Americans don't want facilities built nearby, citing worries over electricity prices, eyesore buildings, and water-hungry operations. This echoes a 2022 report that found Google datacenters were consuming more than a quarter of all the water used in The Dalles, Oregon.
