- A “perfect” P.U.E. is equivalent to 1
(computer power consumption is strictly
equal to the total power consumption). This would imply that there would be no
cooling system, nor ventilation, nor a backup battery charging system. - A typical traditional data center PUE is currently between 1.9 and 2.5
- The best PUEs today are between 1.3 and 1.6
It is also important to note that geographic location and climate come into play when calculating this index. Indeed a datacenter located in a naturally cold area will not have the same cooling requirements and will necessarily consume less energy than a datacenter located in a warmer area.
