What’s interesting is seeing how kWh/GB is so variable – either based on network demand, the reality of the power curve and most importantly for me, when translated into CO2e how the variability massively increases (time and location)

Subject: [Green] Re: [E-impact] Network Equipment Energy Efficiency Metric

Is is useful for network planners to know kWh/peak-GB for an entire infrastructure?

This doesn't try to model reaction of network equipment to increased flows,
but rather to model how infrastructure grows to accomodate higher peak loads?

There is also an induced demand issue.  Networks grow when they fill,
assuming there is revenue to support it.  This is akin to transportation:
