From the UK AI Energy Index
Every indicator carries its source, the period it covers and a confidence level. Where the evidence is insufficient, the Index says so rather than estimating.

How we research this
We work from primary UK sources — DESNZ, NESO, Ofgem, planning authorities and published company documents. Where a figure is modelled by us it is labelled an AI Energy Intelligence modelled estimate, with its assumptions shown. Where the evidence does not exist, we say so.
