19 3. Comparison of water issues: EV and ICE life cycle based water consumption of EV might be higher than from ICE, due to electricity production from hydropower and thermal power plants. For ICE the most relevant influence on water consumption depends on the amount of biofuel blended (biodiesel in diesel or bioethanol in gasoline) water withdrawal and consumption for fuel supply show that ICE about 50% of the water withdrawal and about 80% of the water consumption is needed for the fuel supply EV about 90% of the water withdrawal and about 80% of the water consumption is needed for the electricity supply. Water Issues in Value Chain of EVs and ICE 1. ICE (incl. blending of biofuels) Fossil fuel extraction and refining(e.g. Tar sands, oil shale or traditional oil) Cultivation of feedstock for biodiesel and bioethanol (e.g. for B5, E10) Vehicle production 2. EV (only BEV and PHEV): Electricity generation (e.g. thermal open cycle, closed cycle, or hydro power) Battery production (specifically due to of pollutants for mineral extraction)
