Which one of the following is not true for an electric vehicle?a.eco-friendlyb.high performance and low maintenancec.inexpensived.uses rechargeable batteries

Nowadays there is a debate on whether electric cars (EV) are more ecological and economical compared with normal gasoline cars (internal combustion engine, ICE). As materials engineers, we have the knowledge to solve this debate. We did a literature review and we found the following information:- The CO2 emission for the fabrication of an EV and an ICE car is the same and equal to 10 metric tonnes of CO2. However, EV cars depend on Li-Ion batteries. The fabrication of a 100 kWh battery pack adds to the EV fabrication another 12 metric tonnes of CO2 emissions. -ICE car consumes non-renewable fuel that produces an average of 5 metric tonnes of CO2 annually. EV cars consume electricity which is produced by a combination of renewable (solar, wind, hydro) and non-renewable energy sources, producing an average of 2 metric tonnes of CO2 annually. How many years will it take for the EV to be more ecological (less total CO2 emissions) than the ICE car?  Kysymys 2Valitse yksi:a.4 yearsb.many years because fabrication of ICE  car produces only 10 metric tonnes of CO2 emissions compared to EV that produces 22 metric tonnes of CO2 emissionsc.0 years. EV is immediately more ecologicald.8 months

Which of the following is not a challenge for electric vehicle adaptation?  High Capital Cost Charging Infrastructure Less emission Driving Range

the manufaturing of electric cars, including EV batteries

After careful thinking, can we say that EV cars are better than ICE cars?Kysymys 4Valitse yksi:a.Considering questions 3 a and b, we cannot give a specific answer on whether an EV car is a better overall option. We will be able to give a specific answer if a) we know the exact needs of each individual person or household and b) consider also advancements in technology that can lead to changes in ecological impact and costs. b.No we cannot knowc.Yes EV cars are better than ICE carsd.Considering questions 3 a and b, we can clearly say that EV car is a better overall option if we plan to keep it for more than 5 years and we travel more than 10 000 km per year.

Which of the following is a disadvantage of renewable energy?a.High pollutionb.Available only in few placesc.High running costd.Unreliable supplyClear my choice
