A method and a system are provided which support reducing domestic energy consumption and contribute to widespread use of expensive energy conservation support devices and home energy generators. The system comprises a device installation supporting portion (NK1) for obtaining and displaying information about a model to be installed and installation timing in accordance with a device list concerning an energy conservation support device having energy conservation effect of reducing energy consumption, an energy conservation effect managing portion (NK2) for determining and displaying energy conservation effect record in accordance with a measured value of the energy consumption at home after installing the energy conservation support device, an energy conservation control portion (NK3) for executing energy conservation control for increasing energy conservation effect when the energy conservation effect record is less than a predetermined value, and a payment process portion (NK4) for executing a process or issuing an instruction for depositing a payment amount of amortization payment for a facility cost of the installed energy conservation support device in a predetermined account. Thus, a solar cell can be used widely at home with zero initial investment. <IMAGE> |
