SUMMARYA Grundfos report warns that Europe’s rapidly expanding datacenter sector could put serious strain on water supplies, electricity grids, and local infrastructure. It says server farm IT load is projected to rise sharply by 2030, with cooling systems consuming a large share of energy and hyperscale facilities using vast amounts of water. The report urges regulators to require water and energy efficiency in approvals and to promote incentives for efficient cooling and district heating integration.

A new Grundfos report warns that Europe's datacenter boom could strain water supplies and power grids unless regulators bake water and energy efficiency into planning, reporting, and incentives for new facilities. The Register reports: According to the report, the EU-wide server farm IT load is about 10 GW today, and is expected to rise to 35 GW by 2030 -- just four years away. These facilities account for about 3 percent of all electricity consumption now, but this is projected to hit 7-9 percent by the end of the decade. Water and energy are intertwined in cooling systems. Grundfos claims that cooling infrastructure accounts for a substantial share of a datacenter's resource use, representing about 38 percent of total electricity consumption in an average facility, while water demand in large hyperscale facilities can reach 11,356 to 18,927 cubic meters per day -- enough for up to 155,000 EU households.

Rapid growth in bit barns is placing increased pressure on energy systems, water resources and local infrastructure, the report notes. Without careful coordination, inefficient or poorly sited facilities risk exacerbating these problems and triggering public opposition. [...] Grundfos advises regulators to integrate water efficiency and cooling design requirements directly into planning approvals for new facilities and any large-scale expansions to encourage adoption of efficient cooling technologies. It also advocates investment incentives from governments such as tax credits, green financing mechanisms, and grant programs for technologies that demonstrably reduce energy and water consumption. Integration between server halls and district heating networks is another aspect worth consideration, the report adds.
