Data Center Energy Efficiency: PUE and Best Practices
Data Center Energy Efficiency: PUE and Best Practices Data centers use a lot of electricity, and teams look for clear goals. A simple, reliable measure helps a lot: PUE, or Power Usage Effectiveness. PUE = total facility energy divided by energy used by IT equipment. A lower value means less energy is wasted on cooling, lighting, and power distribution. In modern facilities PUE often sits around 1.2 to 1.5, while older sites may be higher. PUE helps teams compare designs, track improvements, and justify upgrades without blame. ...
