2、e power.To measure the operating efficiency of our data centers,we compare the total amount of power we source from our utility with the power used to run the hardware within the data center.The ideal PUE is 1.0,meaning that every electron entering the site is used to power the hardware inside the d
3、ata center.The industry average PUE is 1.5,and were proud that our facilities have averaged 1.11 or below for the last five years.We still continue to look for additional ways to get even closer to 1.0.-Annual Data Center Water Usage Effectiveness(WUE)Industry AverageWater Usage Effectiveness(WUE)is
4、 a water efficiency metric that 1.5 compares the amount of water we use to the amount of energy that is used by our hardware.Since we started tracking and reporting on this metric in 2012,we have consistently kept our WUE stable-and extremely low.We are also proud that Facebook was 1.0 the first to
