A broadband gateway may provide energy management service within a home network. The energy management service may enable reducing and/or enhancing energy consumption within the home network. The energy management service may comprise managing one or more devices in the home network by the broadband gateway. The energy management service may be performed based on energy-related information associated with devices, and the information may be stored by the broadband gateway. At least some of the energy-related information may be acquired from the managed devices. The energy management service may comprise controlling and/or configuring the managed devices, and/or communications between the managed devices within the home network. The broadband gateway may track actual energy usage by the managed devices. Information corresponding to energy-related activities and/or usage may be displayed via a user interface. The information may also be reported to entities external to the home network.
