The European Commission has proposed a rating scheme grading data centers over energy and water efficiency as the bloc seeks to push for more transparency over their impact as they place new demands on Europe's energy system.
The commission's statement noted that data centers were important for the bloc's digital future, as it seeks to triple its data center capacity over the next five to seven years, leading to increased pressure on electricity grids and natural resources such as water, while contributing to higher carbon emissions.
Aimed at ensuring transparency over data center resource consumption, the rating scheme would cover all projects with a capacity greater than 500 kilovolts.
Data centers consumed about 68 terawatt-hours of electricity in the EU in 2024, with consumption expected to jump to nearly 114 TWh by 2030, representing 3% of the region's total power demand, the commission said, citing International Energy Agency data.
The commission also touched upon the reuse of waste heat generated by data centers, noting that just half of it was equivalent to the heating demand of 4 million households.
