[APRIL FREE REPORT]-TECHNOLOGY OF CARS THAT REDUCE AIR POLLUTION. |

Introduction. Cars and trucks are one of the leading causes of air pollution. Always, cars and trucks burn gasoline and diesel fuel to produce energy, while nitrogen dioxide, carbon monoxide, hydrocarbons, benzenes, formaldehydes, and other byproducts of combusting fuels are greenhouse gases that pose a greenhouse effect around the world. "Is it true that this developed world can't live without cars, airplanes, and other automatic vehicles that don't burn diesel, petrol, or gasoline for their operation?" - Please help me answer this question in the comment section. Discussion. My answer (you may provide yours) is no. Today, we have a lot of companies working to create electric vehicles that won't burn organic substances for energy production, and most of these companies have succeeded in their research. We have three types of electric vehicles: 1. Battery electric vehicles (BEVs) contain special batteries that act as the source of mechanical energy for vehicles; most of these batteries are made up of lithium-ion, which is actually expensive (this is why these vehicles are so expensive but save on climate change). These batteries are charged using grid electricity. 2. Plug-in hybrid vehicles: These cars use batteries to power electric motors and gasoline combustion through internal combustion when needed. These batteries are rechargeable using a special wall outlet for charging equipment, by internal combustion of gasoline, or through regenerative braking. 3. Hydrogen fuel cell vehicles: These cars use hydrogen gas to produce electric energy by splitting hydrogen gas into hydrogen atoms and then using the produced energy as a source of mechanical energy. (These cars' fuel is hydrogen gas.) Apart from electric cars, most vehicle companies modify fuel cars to reduce the amount of greenhouse gases emitted in the atmosphere (they are also known as clean vehicles); they emit greenhouse gases from fuel combustion but in a low amount. The kind of modification that was performed on these clean vehicles is that they are using a small amount of fuel in their operation, hence a little burning and a little emission. Conclusion. Electric cars, as discussed above, are very expensive, apart from the fact that they are climate-saving vehicles, so the world must invest in electric vehicle research to improve this technology; hence, some of these cars will be sold at a cheaper price compared to these fuel vehicles. Also, we should improve our understanding of using clean vehicles instead of outdated ones that emit high amounts of greenhouse gases.

Hello Baraka! This is your mentor Yewon.
Before I start, I apologize for the late comment.
You have written an interesting report about the technology of cars that reduces air pollution!
I haven't thought of this topic, so it was a great chance for me to learn more about it.
Especially it was impressive that those three different types of cars have very different ways.
Thank you for your meaningful report! Great job!

Hello again Baraka! This is your mentor James.
Again, really sorry for my late comment.
I see that you've selected to discuss about different types of EVs which emits less or no air pollutants and GHGs. In terms of BEVs and PHEVs, a lot of technological advances are already made and we can see quite a number of them in countries like Japan, the U.S, and China. However, FCEVs are yet to be developed and commercialized, and in my opinion, FCEVs are the ultimate goal for zero carbon emission vehicles.
Thank you for this writing meaningful report! Let's keep up the good work.
