微软 Nadella 谈算力瓶颈：缺电不缺 GPU
原来卡住算力的是电不是芯片，Nadella 说 GPU 可能堆着没电插，OpenAI 还想让美国每年多建 100 吉瓦发电。
Satya Nadella 去年就指出微软没有足够电力来给全部 AI GPU 供电，芯片可能闲置成堆。真正稀缺的不是芯片，而是靠近大型电网接入点的“warm shells”（已建成、可接电的数据中心建筑）。OpenAI 正推动美国政府以每年新增 100 吉瓦发电能力作为 AI 战略资产。GPU 在等待变电站和输电设施就绪期间持续贬值，形成搁浅资本；而电力与建设审批以多年为周期，GPU 供应却按季度扩张。
Satya Nadella already said last year that the company doesn’t have enough electricity to power all its AI GPUs. He said they might end up with a pile of chips just sitting around because there’s not enough power to plug them in.
The issue is not supply of chips but missing “warm shells” (empty but utility-ready building ), meaning finished data center buildings near large power feeds.
OpenAI is pushing the U.S. government to add 100 gigawatts per year of generation as a strategic asset for AI.
This power gap creates stranded capital since GPUs depreciate while waiting for buildings, substations, and transmission to be ready.
Even if training stays centralized, inference demand is the big driver for electricity, so any shift of queries to efficient edge devices would change grid and data center sizing assumptions.
The main problem is, power delivery and construction schedules run on multi-year permitting and build cycles, while GPU supply ramps in quarters.
