PUE (Power Usage Effectiveness)
PUE is the ratio of total facility power to IT equipment power, measuring datacenter efficiency.
Definition
Power Usage Effectiveness (PUE) is the industry standard metric for datacenter energy efficiency, defined as: PUE = Total Facility Power / IT Equipment Power. A PUE of 1.0 means all power goes to IT equipment (impossible in practice). Average datacenter PUE is 1.55 (Uptime Institute 2024). Best-in-class hyperscale datacenters achieve 1.10-1.20. Harch Corp's datacenters in Morocco achieve PUE 1.08-1.24 thanks to: (1) free cooling from Morocco's temperate climate, (2) hot aisle containment, (3) liquid cooling for GPUs, (4) AI-optimized HVAC control.

Datacenter
A datacenter is a facility housing computer systems and networking infrastructure for computing and storage.
Carbon Intensity
Carbon intensity measures CO2 emissions per unit of electricity consumed, expressed in gCO2/kWh.
Liquid Cooling
Liquid cooling uses liquid instead of air to cool datacenter servers, enabling higher density and efficiency.
