Data Center Water Use Efficiency

The new water usage effectiveness wue metric.

Data center water use efficiency.

Today many data centers adopt new cooling methods that are more energy efficient and use less water than traditional chillers and cooling towers combinations. These cooling methodologies reduce annual water consumption by integrating evaporative cooling technologies and an economizer that utilizes outdoor air. However data center experts say there s usually a trade off. The researchers found that most water use at data centers is indirect since it takes an average 2 gallons of water to generate 1 kwh of energy in the united states while an average data center uses 0 48 gallons of water for cooling for every kwh it consumes.

Effectiveness ere data center compute efficiency dcce and others. By using wue in conjunction with power usage effectiveness and carbon usage effectiveness metrics an organization can reduce energy use and in effect reduce the amount of water and electrical power needed to run the data center efficiently. The new water usage effectiveness wue metric combined with the pue and carbon usage effectiveness cue metrics enables data center operators to quickly assess the water energy and carbon sustainability aspects of their data centers compare the results and determine if any energy efficiency. According to the green grid a water use metric allows a data center manager to understand the effect water consumption has on the local electric grid.

The green grid proposes this new metric to address water usage in data centers which is emerging as extremely important in the design location and operation of data centers in the future. In addition to our efforts on energy efficiency and our goal to achieve 100 renewable energy for our global infrastructure aws has multiple initiatives to improve our water use efficiency and reduce the use of potable drinking water for cooling data centers.
