To reduce emission of carbon dioxide discharged from a car, the carbon dioxide being produded from fossil fuel and contributing to global warming socially concerned, the fossil fuel being used in a vehicle having an internal combustion engine such as a diesel engine or a gasoline engine, and the fossil fuel being also used in a hybrid car uses both an electric motor and an internal combustion engine recently developed.

A wind power generation hybrid car and a wind power generation electric vehicle are equipped with a motor for electricity generation and drive and various small wind power generators instead of the internal combustion engine of the hybrid car using fossil fuel. Similarly, an electric vehicle is also equipped with various small wind power generators. The small wind power generators installed in these vehicles generates electricity using wind power generated by traveling. This electricity is charged in a secondary battery installed in a power source and the vehicles. Although it is necessary for these vehicles to be charged from an external power source, these vehicles can travel while reducing a frequency of charge from the external power source, or eliminating the charge.
