Incremental US data-centre electricity use by 2030, DOE national planning midpoint (published projections 35–108 GW)到 2030 年美国数据中心新增用电（以 GW 计），美国能源部全国规划中值（各方预测 35–108 GW）
Biggest constraint最大约束
Power电力
The biggest constraint is power: large loads must clear grid-interconnection processes such as ERCOT's, and California's laws signed in September 2026 make data centres pay grid-upgrade costs.最大约束是电力：大负荷须走 ERCOT 等电网接入流程，加州 2026 年 9 月签署的法律还要求数据中心承担电网升级费用。
