Clarification on the calculation of Energy of CPU in Case study eshoppen

FAQ

- **Question/Observation**
After reading and looking for explanation in the documentation, I do not understand the following formula for Energy
E = Server utilization * Number of hours * Number of cores * TDP * TDP co-efficient
in this page case study page [eshoppen](https://github.com/Green-Software-Foundation/sci/blob/main/case-studies/eshoppen.md)

- **Suggested Answer**
I ask for answer actually.
Why do need to include the server utilisation, but most of all, how do we get this information ?
can you clarify the TDP co-effecient element.

thanks
