1. An energy management server for use with a device to be monitored comprising an energy meter, the device to be monitored being configured to output energy event described in a form of exchange algebra occurring in the device to be monitored the energy event being a change in a flow or a stock of energy of the device to be monitored as measured by the energy meter, the energy management server comprising:

  • a communication interface configured to receive energy event described in a form of exchange algebra output by the device to be monitored;

    storage configured to store, as a plurality of algebraic data objects, the energy events described in a form of exchange algebra in an energy bookkeeping description including the first term items of exchange algebra describing energy events and a second term items of exchange algebra describing energy events;

    a counting processor configured to, after a predetermined period of time, generate energy accounting data conforming to the energy bookkeeping description by aggregating the energy event described in a form of exchange algebra stored in the storage, based on the first term of exchange algebra describing energy event and the second term of exchange algebra describing energy event;

    a display for displaying the energy accounting data generated by the counting processor;

    whereinthe counting processor is configured to perform a transfer process on a result of aggregation by using exchange algebra, and generates the energy accounting data.
