Power usage effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. A Critical Analysis of Power Usage Effectiveness and Its Use as Data Center Energy Sustainability Metrics. Submitted by Marc Ramsey on Mon. Power usage effectiveness (PUE) is a metric used to determine energy efficiency measurements. PUE is calculated by comparing the total power used by a data.

What is PUE / DCiE? How to Calculate, What to Measure
But how meaningful is that measurement power usage effectiveness the bulk of the servers are just sitting idle or not being very productive? Companies and organizations need IT equipment to provide their products and services, handle transactions, provide security, and to run and grow their businesses.
IT equipment includes computer servers, power usage effectiveness, routers, wiring patch panels and other network equipment. Depending on size, that secure environment is called a wiring closet, a computer room, a server room, or a data center.
What is Power Usage Effectiveness (PUE)? - Definition from Techopedia
In addition to power usage effectiveness energy needed to run that IT equipment, electric power is utilized for lights, security, backup power, and climate control to maintain temperature and humidity levels that will minimize down time due to heat issues.
All IT equipment and anything power usage effectiveness on electricity generates heat. Mark Fontecchio Share this item with your network: Power usage effectiveness PUE is a metric used to determine the energy efficiency of a data center. The total facility power includes all the power used in cooling, air conditioning, lighting and the uninterruptable power supply.
The TFP measurement is taken directly from the energy meter that controls the power supply to the entire data center facility. Rather than the issues mentioned in last paragraph, some other issues are the efficiency of the power supply network and calculating the accurate IT load.
According to the sensitivity analysis by Gemma,  "Total energy consumption is equal to the total amount of energy used by the equipment and infrastructure in the power usage effectiveness WT plus the energy losses due to inefficiencies in the power delivery network WLhence: The PUE value goes up as the data center becomes less efficient.

IT load is another important issue of the PUE metric. With a PUE of 2. The rest goes to cooling, lighting, etc.
The ideal, then, would be a PUE of 1. The average PUE for data centers in the U.
