Europe needs a policy framework that integrates water and energy efficiency if it wants to keep growing datacenter capacity to support its AI and cloud computing ambitions. This is the argument in a report, "Scale and Secure: Powering Europe's Digital Sovereignty," which asserts that progress will depend not so much on access to the right silicon as on water and energy constraints. Grundfos, the Danish firm behind the report, describes itself as a provider of energy-efficient water solutions so has some skin in this game. Datacenters are becoming strategic infrastructure, it says, but their development intersects with energy security, water resilience, industrial policy, urban planning, and technological sovereignty concerns. 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.…
