[0002]

2. Description of the Related Art In modern life, electricity is now indispensable, but electricity is not generated for free, and it costs money. Therefore, from the viewpoint of cost reduction, power consumption is reduced. Reductions are being called for. Also,
Power generation is mainly performed by consuming fossil fuels, and is facing the problem of global warming due to the generation of carbon dioxide gas. Therefore, reduction of power consumption is also a problem in this respect. . For this reason, energy-saving measures centering on reduction of power consumption have been in the limelight, and Japanese Patent No. 2934416 and No. 31800 filed by the present applicant.
Many methods have been proposed, such as those described in No. 98, which can automatically reduce the power consumption.

However, how much electricity is used is ultimately decided by humans, and there is a limit to the automatic method of reducing the amount of power consumption by the machine. Therefore, in order to further reduce power consumption, it is necessary to change the awareness of people who use electricity.
In order to change this consciousness, first of all, invisible electricity
It is important to be able to visually grasp the amount used. And it must be a real-time, easy way. Therefore, the present invention has been made in order to meet such a demand, and is useful for reforming the consciousness to achieve the reduction of the power consumption. It aims to provide a low-cost and feasible cost reduction support system that supports cost reduction of electricity charges by being able to grasp the amount of electricity.
