Introduction and Objectives - Evolution of current router technology may fail in 2020-

The broadband subscribers in the world=215M Why so much energy isin 2005(Penetration=3.35%：WHITE PAPER Information and Communications in Japan). World Population in 2020=7,500M.

Why so much energy is required to transfer

weightless information?World Population in 2020 7,500M. Energy consumption per capita =1/35

Assuming 30% penetration ratio, g p ,Energy consumption per capita in 2020=1/10 of that in 2005 (per

capita)capita)
