Dr Paul Davis says the debate over data centres in Ireland is focusing too heavily on headline figures about water and energy use. In his view, those numbers matter, but they do not by themselves explain the full long-term impact of the sector or provide the best basis for policy decisions.
The issue has drawn sharper attention as Ireland deals with a national hosepipe ban and low reservoir levels. Against that backdrop, public discussion has seized on reports that data centres used roughly a billion litres of water last year, turning the sector into a symbol of pressure on limited resources.
Davis argues that this narrow framing risks missing the wider questions that should shape the national conversation. Looking only at how much water or electricity data centres consume can produce an incomplete picture, especially when the real challenge is understanding broader effects over time rather than reacting to a single set of figures.
His central point is that Ireland needs a more rounded way to assess data centres and their place in the economy and infrastructure system. Instead of reducing the debate to water and power totals alone, he suggests the country should examine the longer-term consequences and trade-offs before deciding what role the industry should play.
