- the electric power charged in the electric vehicle is generated by various methods.
- the amount of CO 2 generated during power generation varies depending on the power generation method. For example, in the case of thermal power generation, a large amount of CO 2 is generated during combustion because fossil fuel is combusted during power generation. On the other hand, in the case of photovoltaic power generation, almost no CO 2 is generated during the process of converting light energy into electrical energy.
- Electric power generated by a power generation method defined as a power generation method that has a low load on the environment, such as power generated by a power generation method that emits less CO 2 is called clean power.

- the electric vehicle V is guided to the destination according to the clean power supply area passage priority traveling route.
- the electric vehicle V passes through the clean power supply area before reaching the destination.
- the display control unit 43 executes a display control routine so that the clean power supply area can be distinguished from the non-clean power supply area.
- a chargeable sign is displayed at the location of the. Therefore, an occupant of the electric vehicle V can confirm the position of the charging station in the clean power supply area through the on-vehicle display 30.
- power including clean power is supplied to charging stations in the clean power supply area. Therefore, the occupant of the electric vehicle V can stop at the charging station in the clean power supply area and charge the power including the clean power there.
- the control device 40 of the electric vehicle V acquires the charging station related information by transmitting the information stored in the database 2 of the information management center 1 to the electric vehicle V.
- the charging station related information may be stored in the storage unit 42 in the control device 40 in advance.
- the display control routine executed by the display control unit 43 and the route guide processing routine executed by the route guide unit 44 are executed by the computer of the information management center 1.
- a route guide may be provided.
- a display control routine and a route guide processing routine are executed by an information terminal device carried by an occupant of the electric vehicle, and charging station information and area information are displayed on the display of the information terminal device together with clean power information and clean power supply information. It may be provided to a vehicle occupant. Further, the first embodiment and the second embodiment can be implemented in combination. As described above, the present invention can be modified without departing from the gist thereof.
