September 28 · Intensity and coolingCommercial electricity intensity exceeds 14.9 kWh/ft² (2003 high) in 2031–2032; data-center cooling up to 2.9×; High-vs-Baseline cooling +84 BkWh in 2050; post-2040 Counterfactual extra efficiency 10%/3 years.
AEO intensity assumptions — not AESO 1,200 MW; not MISO 120-day; not LBNL 649 TWh.
