Abstract
Purpose - Beside the examination of electric power from renewables, this study has sought the answer as to what a ratio of vehicles fueled by environmentally sparing technologies represent in the vehicle fleets of Hungarian settlements. It has been to shed light on the self-sufficiency of Hungarian settlements with respect to these two segments of energy consumption. Design/Methodology/Approach - When looking into self-sufficiency, the focus has been on the ratio of locally available renewable energy sources. Which settlements have the largest numbers of alternative-powered vehicles, and within the vehicle fleets of the settlements where these vehicles represent the most significant shares. The focal point of the studies has fallen on the spatial distribution of electric and hybrid vehicles, as well as vehicles powered with various biofuels. The composition of the vehicle fleet has been examined in the light of the quantities of renewable energies generated in the individual settlements in order to see whether there are settlements in Hungary that are capable of covering the energy needs of their vehicle stocks from local sources. Findings - Among the Hungarian settlements, there are 30 settlements that are able to generate more green electricity than their annual electric power demands. One of the potential ways to utilize the electricity from overproduction is to charge the electric and hybrid vehicles belonging to the settlement, which can be used to supply energy to local transport, as well. Research limitation/implications - The settlements that are up to self-sufficiency still have not had an electric vehicle fleet that would consume the excess energy locally. On the other hand, the settlements that are in possession of significant quantities of electric, hybrid and biofuel-powered vehicles seem to be unable to satisfy the energy demanded for the operation of these vehicles with renewable energy produced in their own areas. Besides, these vehicle fleets account for only a fraction of all the vehicles registered in the settlements concerned. Practical implications - One of the potential ways to utilize the electricity from overproduction is to charge the electric and hybrid vehicles belonging to the settlement, which can be used to supply energy to local transport, as well. Social implications - The results serve as useful feedback in relation to the outcomes of the governmental or municipal measures, allowances and subsidies taken and provided for spreading environmentally friendly technologies until the end of 2017, in the energy transition process of Hungary's system of transportation. Originality/value - Determining municipal energy self-sufficiency by examining the settlement stock of an entire country (in the electricity and transport sectors).
