From Power to Performance: Rethinking What Efficiency Actually Means

SDEA will present at the Data Center Energy Efficiency & Sustainability Summit in London, making the case for measuring energy where it actually gets used.

The datacenter industry is demanding gigawatts. Grid operators are struggling to keep up. Governments are debating moratoriums. And yet, facilities across Europe are running at a third of their capacity, with servers averaging 12-18% utilization and millions of machines consuming power in perpetual idle.

Before the industry builds the next power plant, perhaps it should figure out where the energy is actually going.

That's the argument SDEA Head Matthias Haymoz will make at the 2nd Data Center Energy Efficiency & Sustainability Summit in London on April 29-30. The session – "From Power to Performance: Rethinking Energy Efficiency in Data Centers" – challenges the assumption that grid constraints are purely a supply problem. The real issue, the presentation argues, lies inside the racks: underutilized infrastructure, unmeasured IT systems, and a disconnect between energy consumption and productive output.

About the Event

The 2nd Data Center Energy Efficiency & Sustainability Summit takes place April 29-30, 2026, at the Millennium Hotel London Knightsbridge. Organized by Future Bridge, the event focuses on practical strategies for efficiency, compliance, and resilience in grid-constrained markets. More info

The keynote makes a straightforward case: operators who understand their energy flows today will have a decisive competitive advantage tomorrow, while others wait for grid capacity that may never come.

The summit brings together operators, engineers, and sustainability leaders from across Europe to address some of the most pressing challenges facing the industry – from EED and GHG disclosure requirements to high-density cooling for AI workloads and the economics of heat reuse.
