Power Usage Effectiveness: What It Means and Why It Matters
Power Usage Effectiveness (PUE) is a fundamental metric for measuring how efficiently a data center consumes energy – especially crucial in today’s cloud-first, energy-conscious IT landscape. At its core, PUE is the ratio of a data center’s total energy consumption to the energy consumed by its IT equipment: PUE = Total facility energy / IT equipment energy A PUE of 1.0 represents the ideal – where every watt of energy supports computing, with none lost to cooling, lighting, or overhead. In the real world though, data centers require additional power to keep servers at optimal conditions, pushing PUE above 1.0. …
