What does Influence Power Consumption on Networking Devices?

First part of a video on power utilization and optimization in routing/switching devices.
We breakdown a router in its active elements and describe which factors drive the energy consumption for each of them.
The second video is dedicated to the optimization features:    • Energy Savings in your Network?
