Advanced ways to improve your data center’s PUE

A substantial part of a data center's energy consumption goes into cooling its servers. That makes picking the right methods and technologies for cooling, power distribution, and heat reuse critical for improving Power Usage Effectiveness (PUE).

Why data center Power Usage Effectiveness (PUE) matters

As our world is getting increasingly connected, the global need for data storage and processing is snowballing. By 2025, global demand will be an estimated 180 zettabytes – the equivalent of every single person alive today needing 48 laptops for data storage. 

But a data center consumes significant amounts of power for cooling IT equipment. This makes the reduction of data center energy consumption an important battle in the world's green transition.

Power Usage Effectiveness (PUE) provides the data center industry with a metric to determine the power efficiency of a data center. Power Usage Effectiveness indicates how much of a data center’s total power usage goes to the center’s IT equipment alone.

To obtain a lower PUE takes a smart combination of methods and technologies. Below we offer insights and solutions regarding HVAC, power distribution, energy storage, and heat recovery that support a reliably high uptime and drive down power usage effectiveness.

Methods and technologies for improving power usage effectiveness

The green transition has industries across the globe working with improving energy efficiency. In the data center space, Power Usage Effectiveness (PUE) has become a focal point. Below, you can find insights on how to lower power usage with more efficient equipment, reuse energy consumed, and cut energy costs in any data center.
