Amazon’s data centers used 2.5 billion gallons of water last year
亚马逊去年数据中心耗水量达 25 亿加仑
Just after Seattle enacted a one-year data center moratorium that some of Amazon’s own employees pushed for, Amazon shared how much water its data centers use, reportedly for the first time. 就在西雅图颁布了一项为期一年的数据中心建设禁令（该禁令得到了亚马逊部分员工的推动）之后，亚马逊据称首次披露了其数据中心的用水量。
With concerns about water consumption and energy use a focus of new AI data center construction debates, Amazon says its global data center operations consumed 2.5 billion gallons of water in 2025 at a rate of 0.12 liters per kilowatt-hour of electricity, dropping by two percent from its 2024 total even as it expanded operations. 随着对水资源消耗和能源使用的担忧成为人工智能数据中心建设辩论的焦点，亚马逊表示，其 2025 年全球数据中心运营共消耗了 25 亿加仑水，每千瓦时电力的耗水量为 0.12 升。尽管业务规模有所扩大，但这一数据较 2024 年总量下降了 2%。
Amazon also claims it’s using water more efficiently than some Big Tech rivals — this graphic in Amazon’s report points to Microsoft, Google, and Meta data showing each using more water per kilowatt-hour than Amazon did over the past few years. 亚马逊还声称其用水效率高于部分科技巨头竞争对手——亚马逊报告中的图表显示，微软、谷歌和 Meta 在过去几年中每千瓦时的耗水量均高于亚马逊。
Google by far used the most; however, it appears the data cited is focused specifically on Gemini AI datacenters, while Amazon is reporting on all of its operations. However, Amazon’s data doesn’t factor in indirect water usage at the power plants providing electricity for its data centers, or things like water use from new data center construction. 其中谷歌的耗水量遥遥领先；然而，所引用的数据似乎专门针对 Gemini AI 数据中心，而亚马逊报告的是其所有业务的运营情况。此外，亚马逊的数据并未计入为数据中心供电的发电厂的间接用水量，也未包含新建数据中心过程中的用水量。
Amazon says that “about 90 percent of the time” its data centers use air cooling, and uses evaporative water cooling on “the hottest hours of the hottest days,” while also raising its servers’ tolerances for heat. Amazon claims its data centers are seven times more water-efficient than the industry average, based on an adjusted number from a peer-reviewed research paper released last year. 亚马逊表示，其数据中心“约 90% 的时间”使用空气冷却，仅在“最热天气的最热时段”使用蒸发式水冷却，同时还提高了服务器对高温的耐受度。基于去年发布的一篇同行评审研究论文中的调整数据，亚马逊声称其数据中心的用水效率是行业平均水平的七倍。
