Energy charging apparatus, energy saving apparatus, energy consuming apparatus, and method of managing green energy
An energy charging apparatus includes an energy charging unit charging green energy in an energy saving apparatus, a measured amount information acquisition unit acquiring measured amount information that indicates a charged amount of green energy measured by the energy saving apparatus from the corresponding energy saving apparatus, and a certificate issuance unit issuing a certificate for certifying an amount of green energy charged in the energy saving apparatus when a charged amount of green energy charged by the energy charging unit coincides with the charged amount of green energy shown in the measured amount information, wherein the certificate is managed in association with the energy saving apparatus and is discarded if the amount of green energy that is certified by the corresponding certificate is output from the energy saving apparatus.
1. A method of managing green energy comprising:
charging, by an energy charging apparatus, green energy received from a green energy source in an energy saving apparatus;
acquiring measured amount information that indicates a charged amount of green energy measured by the energy saving apparatus;
comparing a charged amount of green energy charged by the energy charging apparatus with the charged amount of green energy shown in the measured amount information; and
issuing a certificate for certifying an amount of green energy charged in the energy saving apparatus if the charged amount of green energy charged by the energy charging apparatus coincides with the charged amount of green energy shown in the measured amount information, or not issuing the certificate if the charged amount of green energy charged by the energy charging apparatus does not coincide with the charged amount of green energy shown in the measured amount information,
wherein the certificate is managed in association with the energy saving apparatus and is discarded if the amount of green energy that is certified by the corresponding certificate is output from the energy saving apparatus.
2. A method of managing green energy comprising:
measuring an amount of input green energy received from a green energy source and an amount of saved energy;
requesting issuance of a certificate for certifying the input amount of green energy;
comparing the input amount of green energy to the amount of saved energy;
issuing the certificate if the input amount of green energy coincides with the saved amount of energy, or not issuing the certificate if the input amount of green energy does not coincide with the saved amount of energy;
acquiring the certificate;
preserving the certificate; and
discarding the certificate if the amount of green energy that is certified by the corresponding certificate is output.
3. A method of managing green energy comprising:
measuring, by an energy consuming apparatus, an amount of green energy that is received from a green energy source and supplied from an energy saving apparatus if the green energy is supplied from the energy saving apparatus;
acquiring a certificate managed in association with the energy saving apparatus and certifying the amount of green energy saved in the energy saving apparatus;
comparing the amount (X) of green energy supplied from the energy saving apparatus and the amount (Y) of green energy certified by the certificate; and
issuing the certificate for certifying the amount of green energy that corresponds to a difference (Y−X) between the amount (X) of green energy supplied from the energy saving apparatus and the amount (Y) of green energy certified by the certificate if the amount (X) of green energy is smaller than the amount (Y) of green energy, and not issuing the certificate if the amount (X) of green energy is larger than the amount (Y) of green energy,
wherein the acquired certificate is discarded and the issued certificate is managed in association with the energy saving apparatus.
