美国AI基础设施建设最大瓶颈已从GPU变为许可。《The Information》地图显示2023年以来有300多项州级和地方数据中心禁令或暂停,今年通过275项,还有75项在审,中西部和南部抵制最强。但现实数据反超担忧:微软新一代AI数据中心采用芯片级闭环冷却,每站每年避免超1.25亿升水,全舰队用水效率自2021年提升39%至0.30升/kWh;谷歌86%淡水来自低中风险源,全球PUE 1.09(行业均值1.56)。2015–2024年研究表明数据中心通过分摊固定电网成本适度降低了居民平均电价。趋势已转为“自带电源”:谷歌500 MW核电、微软835 MW三哩岛、Meta 1121 MW核电协议。

The U.S. AI buildout is running into a harder constraint than GPUs: permission.

The Information’s new map finds 300+ state and local data-center bans or moratoriums since 2023, with 275+ passed this year and 75+ still under consideration; resistance is strongest in the Midwest and South, exactly where hyperscalers want cheap land and megawatt-scale power.

But the backlash against data centers is outrunning the facts.

The most current datacenter is increasingly designed to solve the two biggest fears: water and power bills.

Start with water. Microsoft’s next-generation AI data centers use chip-level, closed-loop cooling that consumes zero water for cooling and can avoid more than 125 million liters per year per site.

Its fleetwide water-use efficiency has already improved 39% since 2021, to 0.30 liters per kWh.

Google reports that 86% of its freshwater withdrawals come from low- or medium-risk sources, and its global data-center fleet runs at a 1.09 PUE versus a 1.56 industry average—meaning far less wasted overhead energy.

Electric bills are not automatically shifted to households, either. A recent causal study of U.S. retail rates from 2015–2024 found data centers modestly lowered average rates by spreading fixed grid costs across more electricity sales.

And “bring your own power” is already the new trend - e.g. Google’s 500 MW nuclear deal, Microsoft’s 835 MW Three Mile Island agreement, and Meta’s 1,121 MW nuclear contract.
