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

[Dean Bogdanovic <[e-mail]>]

I’m really curious how many people understand how electrical grid 
operates,

the difference between active, reactive and apparent power in electrical 
grid. And how the grip operators are balancing power plants to maintain 
the needed power levels, how the operators decide between economic 
dispatch, grid stability and frequency regulation, environmental 
regulations and emissions , operational flexibility at the power plants 
etc.
Until we do, I would not speak about CO2 emissions and other complex 
energy and traffic engineering relations.

Lets first figure out how to report energy consumption by the networks, 
from very basic power consumers (SFPs) to more complex, like topologies. 
And provide the ability to provide the energy consumption information 
about an element, group of elements, part of network or even whole 
network to people who will know what to do with the info.
