The horrible lie about EVs being ecological must stop. Do people seriously not realize how much environmental damage manufacturing those batteries does? I find it absolutely pathetic how everyone's just willing to ignore facts that don't suit their narrative so here are some:

Manufacturing batteries for one car creates about 16 tonnes of CO2.
Running a petrol engine car for a year creates about 2-4 tonnes of CO2.
To make an EV actually more ecological you'd need to run it for about 200000 miles, now show me an EV with more than 200k miles on it.

How did you manage that calculation? I found the average gas emissions to be 1t of CO2 per 2500mi. So 16t of CO2 should actually be 40,000mi.

And that's only because you're taking the worst case for a Model 3 battery when the best case is actually 4.5t. While the mean is apparently closer to 5t, even if we take the median of 10t it's still a lot less CO2 at 25000mi.

Don't forget about the CO2 cost to extract, process, and transport that fuel all the way to the pump too. Actually makes the gas numbers way worse.

Plus a gas car has a lot more components in the drivetrain so the rest of the vehicle production is a bit more CO2 intensive compared to an EV as well.

Also considering batteries can be (and are being) recycled, the need for mining new battery materials will start to slow down, and maybe eventually can stop entirely.

So even if you're being pretty generous to the gas car and somewhat unfair to the EV, the gas car will overtake the EV on CO2 after 5 years.

u/TableSurface can't reply to your comment for some reason. So I'll do it like this:

Did you actually read the article? It had a battery pack replaced TWICE. That car alone caused more environmental damage than a fleet of Hellcats. That's kinda exactly what I was on about here.

Yeah I deleted the comment after I realized the article was a terrible example. You got a really good point and more focus should be put on the battery within EVs. Even though the "car" can last far beyond 200k miles, the battery must last at least as long in order to become more ecological compared to combustion engines. Battery manufacturing obviously needs to be improved.
