尽管美国计划新建近4000座AI数据中心，但建设进度远低于预期。目前仅有802座正在施工，而预计2027年完成的数据中心容量中约60%尚未开工[1]。这种建设与规划的巨大落差反映出美国在AI基础设施扩张中面临的多重困境。
民众反对情绪强烈成为制约因素之一。71%的美国人表示反对AI数据中心建设[1]，多个州和县随之提议或通过相关禁令。与此同时，技术和资源瓶颈进一步加剧了延期问题。虽然数据中心通常需要18至24个月建设，但完工期限正在被拉长[1]。AI计算容量的延期交付率达到50%，远高于传统数据中心的28%[1]。芯片供应短缺、电力紧张、劳动力不足等因素共同作用，使建设面临重重阻碍。
人力资源缺口尤为突出。要按期完成这些项目，美国需额外增加50万电工、30万焊工和55万管道工[1]。与此相关，变压器等关键设备的等待时间已增加两倍[1]，进一步延长了整体施工周期。此外，单座最先进AI园区的成本约80亿美元[1]，这一高额投入也限制了项目的启动速度。能源需求的增长同样令人担忧，到2028年数据中心用电量预计将从当前的8%增至12%[1]。
Public opposition to artificial intelligence data centers in the United States remains widespread, with 71% of Americans expressing disapproval.[1] Despite this resistance, the more pressing challenge appears to be the gap between ambition and execution: while nearly 4,000 new data centers are planned across the country, only 802 are currently under construction.[1]
The construction bottlenecks are numerous and interconnected. Of the data center capacity scheduled for completion by 2027, approximately 60% has yet to begin construction.[1] Data centers typically require 18 to 24 months to build, but completion timelines are being extended.[1] Delivery delays for AI computing capacity have reached 50%, compared to 28% for traditional data centers.[1] Equipment shortages compound the problem, with transformer wait times increasing twofold.[1] A single state-of-the-art AI campus can cost around $8 billion, placing significant financial strain on projects.[1]
Supply chain vulnerabilities further constrain progress. Taiwan Semiconductor Manufacturing Company (TSMC) chip supplies represent a single point of dependency for the global AI supply chain.[1] The United States also faces a critical labor shortage, needing an additional 500,000 electricians, 300,000 welders, and 550,000 plumbers to complete projects on schedule.[1] Power availability poses another constraint, with data center electricity consumption projected to rise from the current 8% of national usage to 12% by 2028.[1] In June 2027, data center construction spending reached $68.3 billion, representing a 46% increase year-over-year.[1]
