Electric vehicles will likely play an increasingly important role in urban environments where large quantities of electricity are readily available. However, installing charging stations outside of cities and in more rural environments is challenging, and would require major infrastructure changes.  Converting gas stations to charging stations would require changes in how electricity is distributed. Suddenly, gas stations would require far more power than they previously did. The same problem exists when considering installing charging stations in rural towns. A location would suddenly need more power, but there would be no infrastructure to accommodate that change in demand. Because of the challenges with installing charging stations outside of cities, it is unlikely electric vehicles will play a major role outside of urban environments.
Infrastructure changes will be required to support the shift to electric vehicles, but many governments have committed to supporting cleaner forms of transportation.  While there may be challenges, humans alter and create infrastructure constantly, and expanding car charging networks would just be another change.
