A power source provides power (e.g., electrical power) to a powered object. The object is identified and the amount of power consumed by the object is measured. Information representing the object identity and the amount of power consumed by the object is transmitted to a remote server. Proximity between a device and the object may be determined, in response to which the device may obtain the information representing the object identity and the amount of power consumed by the object, and transmit such information to the remote server, in addition to information representing an identity of a user of the device.
