## Question put to the AI subject

What share of Ireland's 2021 metered electricity did data centres account for, per the figure cited in the OECD Digital Economy Outlook 2024 chapter (sourced from Ireland's CSO 2023)?

## AI subject's verbatim answer

Data centres consumed **14%** of Ireland's total metered electricity in 2021 — a figure drawn from Ireland's Central Statistics Office (CSO, 2023) and cited in the OECD Digital Economy Outlook 2024. [...] The data-centre share of metered electricity rose from 5% in 2015 to 14% in 2021, 18% in 2022, and 21% in 2023. This represents a near-quadrupling in eight years.

## Verbatim regulator text contradicting the answer

> data centre energy consumption increased by 144% between 2015 and 2020, accounting for 11% of metered electricity consumed in the country in 2021 (Central Statistics Office, 2023)

_Source:_ [R6-REPORT_CHAPTER-00024](https://reglegbrief.com/substrate/INT/OECD/OECD-DIGITAL-TECHNOLOGIES-ENVIRONMENT-2025/R6-REPORT_CHAPTER-00024/source.html)
_Section anchor:_ Energy demand and consumption — Ireland data-centre share of metered electricity in 2021 (citing CSO, 2023)

## Failure mode

**`inference_drift`** — Inference drift — the AI inferred a conclusion the regulator's text does not warrant, often by combining unrelated provisions.
