1. A demand response method comprising:

  • generating first data comprising information about charge rates for a unit of power for respective time spans;

    generating second data comprising information about amounts of power used for the respective time spans;

    calculating, by a computer, third data comprising information about index power charges for the respective time spans calculated based on a combination of the first data and the second data; and

    dividing the third data into a plurality of index sections such that dense index sections are generated in the time spans in which the index power charges are above a predetermined, index power charge threshold;

    generating a Demand Response (DR) signal when use of the power is in an index section of the plurality of index sections in which each real-time charge for the power is present;

    outputting the DR signal to an electric home appliance;

    controlling the electric home appliance in response to receiving the generated DR signal,wherein the dense index sections are denser index sections, at least at a point in time, than others of the index sections, at the point in time, and the others of the index sections are below the predetermined index power charge threshold.
