In a transition towards 100% renewable energy system, transportation sector is rarely dealt withusing the holistic approach and measuring its impact on the whole energy system. Furthermore, assolutions for power and heat sectors are clearer, it is a tendency of the researchers to focus on thelatter two energy sectors. In order to deal with the raised issue, authors of this paper developed amethodology for calculation of the transition towards sustainable transport sector, focusing on thesolutions that are already available. Furthermore, as a part of the model, a detailed mapping ofresources needed has been carried out for each of the alternatives. It was shown that theelectrification of the transportation sector is a crucial point in transition, while for the transportmodes that cannot be electrified, or shifted to different transportation modes, four alternatives weredefined: synthetic fuels, biofuels, hydrogen and synthetic fuels utilizing excess intermittentelectricity generation. Results showed that the 72.3% of the fossil fuel demand in transportationsector of the European Union (EU) can be replaced by electricity demand, reducing final energydemand in transportation sector for 50.6% or 2,051 TWh. All the alternatives for the non-electrifiedpart of transportation suffer from the low well-to-wheel efficiency, resulting in a significant amountof additional resources needed. Replacing remaining part of the fossil fuels by biofuels led to theincreased demand for biomass on EU level equal to 3,069 TWh, which is extremely challenging tomeet in the future in a sustainable way. In the case of synthetic fuel production as an alternative,additional electricity demand was calculated to be 2,775 TWh, which is approximately 90% of thetotal electricity demand of the EU for the year 2013. Hence, authors argued that due to the enormousadditional demand for scarce resources for producing alternatives to the fossil fuels, concepts suchas car sharing, induction charging on highways, promotion of bicycling and public transportationshould be assessed in more detailed way in order to bring additional energy savings in the sector.
