The longer an EV is used, the more beneficial for the environment it becomes, and the battery can be recycled. Gas powered cars are much less energy efficient and have more maintenance problems.

Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

That technology connections video where he burned the equivalent amount of fuel an engine uses in a second was really eye opening. It was something crazy like eight tablespoons a second.
The video in question. at about 8m 35sec.
It's 8 tbsp per minute, not per second
the battery can be recycled
Citation needed.
Thats a lab that's doing research...because the premise is that the batteries are not currently recyclable
The simplicity of an electric motor compared to a gas engine at a general level is pretty incredible, how could EVs not be more efficient and far more simple to maintain?
It wouldn't make basic logical sense outside of outlier edgecases for combustion engines to be more efficient.
I've had an EV for quite a while. It was used when I got it and quite aged now. I had the get new tires and new brake pads a few times. Thats it. In total. For almost 6 years.
Oh the reservoir for the wiper fluid is cracked, but like, I'm going to get around to fixing that. I swear.
A gas powered vehicle is hot and constantly trying to rattle itself to pieces.
Just operating at a lower temperature and not like, violently rattling constantly seems more than sufficient to explain the reduced maintenance.
That's because ICE engines work by relentlessly blowing shit up. It's the most primative technology aside from the wheel or the lever.
How it's still the norm after so many years is beyond me. Actually no, we know the dark story of why that is.
But yeah, tiny explosions to move a vehicle is caveman shit.
In what world is using complex chemicals for combustion "primitive"? I don't recall cavemen ever having access to explosives of any kind either.
The many fluids, the heat, the vibrations, the pistons, the belts, the transmission, the exhaust, the alternator. ICE vehicles are controlled chaos!
That's something I love about my Bolt, the absolute stillness, no shuttering, no annoying noise, just pure acceleration. Someone even asked me "don't you miss the sound of the engine?" Obviously, no, I don't. Some people can be so weird about the things they're afraid of changing.
How's the cost of battery replacement or does roadmaster usually time with vehicle end of life?
I'm expecting to get at least 250k miles out of my Bolt EUV. At that time, if I still have it, and the batteries outlast the car, I'll take the batteries out for a whole home battery backup if they have any capacity left.
Go for 300k! I believe! 🔋
Oh, I suspect a full half a million is quite possible with maybe just changing out a pack or 2. I think as battery tech progresses, in the future you might be able to purchase a car sans battery and just transplant your old cars battery to the new car. It's amazing what mass adoption of cellphones have done to progress battery tech in my lifetime.
I'm sure the study goes deeper but engineering explained did a video, even if you run on a coal power plant you can recoup the environmental impact within the lifetime of the EV.
I was most shocked when I learned it was about a gallon and a half of energy (okay energy transfer isn't 100%, maybe 2.5 gallons of energy) to fill an electric car battery, that can then travel hundreds of miles.
