Figure 3 reports several values concerning the Life Cycle Analysis of GHG emissions from electricity generation technologies. he difference between fossil fuels and RES is extremely significant. In this study an average value obtained by values reported in Figure 3 is chosen for the fossil fuels: ECDOIL = 824 gCO2eq/kWh, ECDCOAL = 1149 gCO2eq/kWh and ECDGAS = 568 gCO2eq/kWh.
Compared to traditional internal combustion engines cars, which are powered solely by diesel or unleaded gasoline, the electricity for EV charging can be generated from various energy sources—conventional (e.g., lignite, coal, natural gas) and renewable (e.g., biomass, biogas, solar energy, wind energy, hydro energy).
The results shown in Figure 5 revealed that for the Polish case study, charging batteries with electricity from the mains may be more harmful to the environment than using ICE cars.
Electricity consumption also has a significant impact on the environmental performance of electric cars. The EV with high electricity consumption may turn out to be less eco-friendly than standard ICE cars.
Among the analyzed classes, this is the case in the City class, where indirect emission, assuming battery charging from the grid, is higher (3.17 kgCO2∙day−1) than direct emission of diesel (2.70 kgCO2∙day−1) and lower than direct emission of gasoline cars (3.30 kgCO2∙day−1).
Among the analyzed energy sources, the highest MREC-CO2 emission is characterized by solid biomass (1440 kgCO2∙MWh−1). However, in this case, the overall balance of carbon dioxide emissions into the atmosphere is zero or insignificant, due to the equivalent amount of carbon dioxide absorbed by biomass during the plant’s growing phase.
The results show that the average indirect CO2-equvalent emissions for the selected electric vehicle model were 92 gram CO2 per kilometer (vs. Diesel 163.87+).
