We <i>Still</i> do not know how much energy is required when we send a packet from Japan to Brazil - one major criterion to evaluate the energy efficiency of today’s internet. How would you like to work on this?
I think one can only try to calculate the RANGE for utilized energy for a packet (but just for non-related packet)... if you go in terms of data, the count of assumptions of successful delivery, network availability, and many more features would hinder the correct judgement
I'd think this packet would pass a variety of totally different routing equipment with different energy consumptions
