Here are some sources and references you can use for estimating the energy of computing resources:

  1. Cloud Jewels coefficients The following coefficients are provided by Cloud Jewels for how many watt-hours (Wh) it takes to run a virtual server and to store a terabyte of data on HDD (hard disk drive) or SSD (solid-state drive) disks in a cloud computing environment:
  • 2.10 Wh per vCPUh for Server
  • 0.89 Wh/TBh for HDD storage
  • 1.52 Wh/TBh for SSD storage
  1. Avg Watts - Active Idle time for servers
