Here, the authors propose the concept of a local electricity‐sharing system as a complement or alternative to a feed‐in tariff to achieve CO2 ‐neutral transportation in cities. In the authors’ proposed system, electricity generated from widely introduced solar photovoltaic panels (PVs) is stored in the cars ‘not in use’ in a city. In Japan, almost half of the cars in the central Tokyo metropolitan area are used only on weekends and thus are kept parked during weekdays. These cars represent a huge new potential storage depot if they were replaced by electric vehicles (EVs), that is, they could be used as storage batteries in a vehicle‐to‐grid system. Using an agent‐based transportation simulator (MATSim), the authors modelled the effects of a large‐scale introduction of EVs and PVs on the hourly regional power demand–supply for Yokohama city, Japan. The results of our simulation suggest that CO2 ‐neutral EV trips can be achieved only during periods with current average solar irradiance.
