Calculate your PUE Goals and Savings

Here’s a neat little calculator from 42U. In a single page, with the input of a few figures which are easily obtained, you can get a good overview of the savings achievable by aiming for a specific Power Usage Effectiveness (PUE). The calculator asks for your existing PUE rating if known, and you can then adjust the target PUE. Input the cost of your electricity and your IT load in Kilowatts and off you go.
