Data Centres in Ireland: Four Reports, Four Verdicts

Four recent reports examine the economic, energy and environmental impact of data centres — three focused on Ireland, and a global UN study on AI. They draw on much the same facts but reach strikingly different conclusions about whether data centres are a net benefit or a net cost.

This interactive dashboard sets them side by side: Digital Infrastructure Ireland's case that data centres are critical infrastructure worth powering; Friends of the Earth Ireland's finding that data-centre demand has pushed household electricity bills up via the gas-dependent grid; KPMG's assessment (for the Department of Enterprise) of the economic value they enable; and UNU-INWEH's measurement of AI's global carbon, water and land footprints.

The comparison lets you move between each report's headline statistics, the arguments behind them, the numbers side by side, and the authors and commissioning bodies. The recurring theme is that the reports rarely measure the same thing — they weigh different ledgers, which is why each can be internally consistent yet point toward a different conclusion.

This is an independent Bitpower summary of the four underlying reports; Bitpower is the author of the comparison only, not of the source research.
