Energy management is a widely distributed problem. there are a number of
areas where IETF participants have been peripherally or directly involved.

Building or network level power management was an activity of the
operations and management area.

Scheduling on air interfaces would tend to fall to other SDO's though as
fred notes, multicast contention and protocol chattiness are
considerations for protocols that fall within the IETF scope, there is
also scope for transport or IRTF related exploration probably.
