Therefore, IC and optical technology and architectural advancements are needed to contain its energy footprint. At the same time, “smart” networking promises significant (> 10%) improvements in the overall energy consumption, primarily from advancements in “smart-grid” power distribution, transportation, and buildings.

Telecom Energy Analysis
R. Tukcer et. al. IEEE OFC 2009
• Planning very critical; – Converged architectures
– Scalable platforms and capacity utilization (ASICs, interconnects, chassis fill factor)
• Access > 60% of consumption• Servers (500 nJ/bit) 1000% more than other equipment
