electric cars reduce the CO2 emissions of our society?

Transcription

1 Can electric cars reduce the energy consumption and the CO2 emissions of our society?

2 A school project at Bundesrealgymnasium 16 Schuhmeierplatz Vienna Austria by Albert Jaros

3 Contents information about the students results of the project problems during the project additional information for the students at the end of the project given by the teacher

4 Class: 6c high school in Vienna / Austria 10th grade 22 students: 16 girls, 6 boys 3 physics lessons weekly project duration: 8 lessons

7 Today electric cars have + no direct exhaust or soot + low energy consumption + low energy costs - short range ( 10² km ) - long time for recharge (1-10 h) - high purchase price

8 Energy density: Accumulators: Pb Li-ion Li-S 0.03 kwh/kg 0.19 kwh/kg 0.5 kwh/kg Fuel: ~ 11.9 kwh/kg

9 Electric cars are useful + for reducing air pollution + for reducing energy consumption for short trips

10 Today electric cars need - a long time for recharging - additional car parks - additional funds

11 Impact of electric cars on + energy balance + CO2 balance costs for new cars - car parks - price of electricity - taxation of electricity

13 Calculated results Reduction of CO2 emissions in Austria: up to 24 % Reduction of energy consumption in Austria: up to 16 %

14 Problems during the project understanding of physical quantities units and orders of magnitude combining statistical data from different sources selecting parameters time management
