[Thematic Report] Green Vehicles |

By now, everyone of us have become familiar with what green vehicles are. Now as for comparisons between electric vehicles (EVs) and conventional engine-operated vehicles, it is a complex process. There is no single estimate that applies everywhere. However some basic comparisons can be like- 1) CO2 emissions from battery-powered vehicles are about 40% lower than internal combustion engine (ICE) vehicles. Emissions are even lower in countries which have large renewable power production and storage capacity. Electric vehicles offer a promising alternative to internal-combustion vehicles because they don't directly burn fossil fuels. 2) EVs are also capable of producing instant torque and smoother acceleration than conventional vehicles. 3) Electric Vehicles (EVs) aren’t without expenses however, the largest possible maintenance expense for an electric vehicle is a replacement battery pack. Unlike a conventional battery, EVs have large, complex rechargeable batteries that are drained and recharged constantly, which leads to degradation and range loss over time. So are electric vehicles really eco-friendly with no emissions? The answer is no, electric cars are not zero emissions vehicles. Although they do not emit CO2 while being driven, they might do it in 3 other stages which are during manufacturing as the need for mining activities to extract the rare earth metals that are used in batteries is very energy consuming and polluting; during energy production i.e., if the car is being powered with energy from burning fossil fuels, it is still releasing CO2 in the atmosphere, not from the tailpipe but from some distant power plant; and finally at the end of their life cycle as when it comes to batteries being recycled, it is still an expensive and ongoing process and most batteries are not being recycled yet. So what can be the solution? The only plausible solution is to adapt to public transportation which seems to be a better option than using individual vehicles if we want to lower our carbon footprint.

Yes mentor Yuseon, we cannot totally give up on developing EVs because they are helpful in lots of ways to us.. Thank you for appreciating this report of mine..

Thank you mentor Debbie.. Hopefully we can restore our ecosystem through our own efforts..

Hi Dalima,
This is your mentor Yuseon:D
Wow what a detailed and thorough research you have for this report.
EV emits less carbon than original ones(ICE), but they still emit a certain amount.
As you have mentioned, we also have to deal with the waste battery problems
as well. You have concluded that public transportation would be the best option.
However, we still have to try developing EV and consider reusing waste batteries for
other purposes.
Thanks for sharing;)

Dear Dalima,
This is your mentor Debbie. :)
I agree that batteries remain a problem to this day! And since the use of EVs are rising, there will be many more waste batteries being produced as well.
Apparently, the industry is working on turning these degraded batteries into ESS (Energy Storage System). Hopefully the harmful substances composing batteries will not affect our ecosystem!! (very worried actually)
Appreciated reading your article! It is very well-organized. :)
Green Cheers,
Debbie
