Current Computer Use Case 

The energy consumption of this machine is Estimated at 62w average via a Kill-A-Watt P3 meter analysis after 3months of data collected. A very energy efficient computer setup compared to every previous desktop system I have ever operated. Some of my old screens used more power then this iMac setup! Great battery run time on the Magic Mouse 2, we shall see how it holds up over time.
