Every day news show that the environment is being destroyed due to human intervention. Green house gas emissions have been increasing excessively and much hasn't been done to avoid this. With this scenario, electric vehicles appeared many years ago and were always seen and presented as a green solution. However, they have been repeatedly put aside in detriment of internal combustion engine vehicles.Portuguese governments have already acknowledged the importance of this matter and have already invested, as well as other European and American countries, on this technology. It is noticeable, due to the issues previously referred, that the interest on this technology has been increasing. Therefore, it is important to evaluate if it is viable to purchase an electric vehicle when compared to a conventional vehicle, in the Portuguese context.
