Data Center Energy Efficiency Measures: How Sensor Precision Improves PUE and Cuts Costs

Data centers currently consume around 485 TWh of electricity worldwide each year. According to an IEA report from 2025, this figure could reach 950 TWh by 2030. Artificial intelligence is one of the main drivers of this increase. 

Companies looking for data center energy efficiency measures should not focus only on IT hardware. Cooling offers the greatest short-term potential. Depending on the location, utilisation and cooling demands, it can account for up to 25% of total facility energy consumption.

Precise and reliable measurement data enables targeted control of energy efficiency in data center cooling without compromising availability.

In this article, you will learn:

• What PUE and WUE mean and why they are important metrics.
• Which measurement points in the data center have the greatest impact on energy consumption.
• What precise sensor technology can achieve in practice.
