Networked infrastructure devices

can’t be switched off or put to
sleep, so the best way to reduce
their energy consumption is to
improve their ability to adapt to
changing levels of traffic intensity.
The existing European codes of
conduct for Data Centres and
Broadband networks are excellent
tools to drive the efficiency of
such systems. For example active
energy efficiency management of
Data Centres can help to reduce
up to 30% of energy consumption
by implementing permanent
changes through measurement,
monitoring, and control of energy
