## Environmental Efficiency Statistics task 

The Environmental Efficiency Statistics task is part of the Monitor task group. It provides historical power consumption and thermal information for the IBM Z CPC, and is available on the HMC. 

The data is presented in table format and graphical “histogram” format. The data also can be exported to a . csv -formatted file so that the data can be imported into a spreadsheet. For this task, you must use a web browser to connect to an HMC.
