Abstract
This paper presents an analysis concerning the effectiveness of electric traction in comparison with conventional cars. The Life Cycle Assessment method is used. It estimates the energy spent for the extraction of the raw materials/sources, manufacturing and transportation of the components and the vehicle, motion, maintenance and repair during exploitation period and the recycling process. The impact of the production technology of the electric energy, needed for charging the battery, is taken into account. The energy consumption and CO2 emissions for the life cycle of electric and conventional cars are presented on graphs. Examples for Bulgaria and EU countries are given. The exploitation conditions in which the electric car is more effective regarding CO2 equivalent emissions are shown. The main influence on the effectiveness of electric cars has the structure of the energy mix of the country where the electric car is produced and is used in exploitation.
Highlights
In view of decreasing the impact of vehicles on global warming in recent years, more and more electric cars replace the conventional ones
There are studies [1,2,3,4] of the effectiveness of electric car vs. conventional ones in terms of emissions of greenhouse gases adjusted to carbon dioxide equivalent (СО2). This type of studies are done using the Life Cycle Assessment (LCA) method [5] and the comparison is made for the energy consumption and/or СО2 emissions
The primary energy is two times less (49%) than the energy spent for BEV-1, 42% less than conventional gasoline (CV) in Bulgaria and 38% less than CV in Norway
Summary
In view of decreasing the impact of vehicles on global warming in recent years, more and more electric cars replace the conventional ones. There are studies [1,2,3,4] of the effectiveness of electric car vs conventional ones in terms of emissions of greenhouse gases adjusted to carbon dioxide equivalent (СО2). This type of studies are done using the Life Cycle Assessment (LCA) method [5] and the comparison is made for the energy consumption and/or СО2 emissions. A full comparative analysis, based on the LCA method and concerning used energy and generated СО2 emissions of electric and conventional cars in Bulgaria does not exist. Primary energy source, for car and battery production, for using the car and for utilizing the old components, have to be considered
