  • the reduction request (specifically, the power saving request) for the energy consumption in the house H is transmitted from the CEMS server 40.
  • the present invention is not limited to this.
  • a power saving request may be transmitted directly from a server other than the server 40, for example, a server owned by an energy supply company (for example, the power supply source server 50 described above).
