Tesla does their own with real world data. It’s a non-issue. Save the planet. Stop making excuses and get an EV.
Etheryte•55m ago
While buying an EV is a greener choice than buying an ICE, a better option still is to use the vehicle you already have for as long as reasonable. This also overlooks the fact that EVs are prohibitively expensive for the vast majority of the population. It isn't the case that people aren't buying them because of preference. Nearly everyone would buy a car that's cheaper to run and maintain if they could afford it.
singinishi•51m ago
All the oil and gas is killing the planet. Even the gas fumes are killing you when you fill up. The sooner the better. There are lots of low cost EVs out there, especially when you factor in there’s no maintenance.
linsomniac•23m ago
The maintenance factor seems to often be overlooked. The amount of time I've put into EV maintenance in the last decade is about the same as I've put into my two ICE cars, but I drive them 1/10th as much. It's really, really nice, and I don't think dealer service departments are ready for a massive switch to EV.
neogodless•21m ago
Mostly agree but own an EV. "No" maintenance is an exaggeration and it's not necessary to make your point.

My car's first set of tires were very bald at 25,000 miles. That's not unusual on new cars in general as they seem to come from the factory with low longevity tires, but it's still quite a short tire life.

Yes anything in a gasoline engine is gone, and brakes get less use.

But there are still maintenance items.

epistasis•50m ago
That's absolutely untrue. The majority of the environmental damage is from the ongoing use of it, not from production.

Every time you fill up on 20 gallons of gas, that is 400 pounds of CO2 that will be dumped into the air.

Used EVs are apparently very cheap. Most new cars are prohibitively expensive, but a used car. The average new car cost is something like $50k now in the US.

dangus•43m ago
To add to this, almost nobody statistically keeps their vehicle very long. People keeping a car for 20-30 years is extremely rare.

The median length of car ownership is something like 7 years. Even if you are switching between used cars, most people are switching vehicles at some point.

From what I understand even considering battery mining and using dirty electrical generation, you’re still at breakeven within a couple years of driving with an EV.

Yeah lithium mining is bad, but don’t forget that oil is also extracted and “mine.” And your gas car uses a LOT of it.

I wouldn’t think too much about then average new car cost of $50k. That average is skewed by:

1. Expensive new car purchases (average != median)

2. Lower income people don’t buy new cars at all.

Still, some of the best new car deals are EVs because dealers can’t get rid of them due to the sudden expiration of federal incentives. Plus the used ones depreciate like crazy despite having better maintenance and lower miles. The lease deals you might get on an Ioniq are insane, good luck getting a gas car lease with that kind of value.

Let’s also not forget that the majority of housing units in the USA are single family homes where charging at home is likely to be an option.

closewith•29m ago
The EU average passenger car fleet age is 12.5 years.

> From what I understand even considering battery mining and using dirty electrical generation, you’re still at breakeven within a couple years of driving with an EV.

Only when compared to buying a new ICE, as it takes 1-2 years average mileage in the US and 2-4 years in the EU for a new EV to reach emissions parity with a new ICE. It takes well over a decade in the EU for a new EV to recover it's production emissions va driving an existing used ICE. It's never environmentally friendly to scrap an ICE for a new EV.

jeffbee•32m ago
It is true though, in some cases. The embodied carbon of a Rivian for example is never paid back by operations. So you do have to exercise good judgement in which EV you choose. The category doesn't always win.

In my case I already own a hybrid that I only drive 2000 mi/yr and there is not yet an EV that I could buy with so little embodied carbon that it would make sense to do so. At the rate China is decarbonizing, presumably the embodied carbon of their EVs will soon be minimal, but not yet.

thinkcontext•3m ago
> The embodied carbon of a Rivian for example is never paid back by operations

Really? I could imagine it being significantly longer than an average EV, but never? Regardless of driving pattern? Got a link or can you show your math?

cogman10•45m ago
Bike > walk == public transit > used EV > new EV > used ICE > new ICE

That's pretty much the order of "greenness" in personal transport.

New EVs will pay off their added carbon footprint in roughly 1 or 2 years in most locations. The ultimate determining factor of how fast that is the energy mix of your local power generation.

The only time it'd probably be better to continue using an ICE is if that ICE is a moped or you live in West Virginia and drive a hybrid. For pretty much all other vehicle choices, switching to an EV will be greener.

closewith•34m ago
Those must be US estimates involving huge mileage, because - taking your existing ICE car's production emissions as an already sunk cost - replacing an existing ICE with a new EV would over a decade of driving the average EU mileage (~10k km) before reaching emissions parity.

It takes 2-4 years of that mileage alone for a new EV to reach lifetime emissions parity with a new ICE in the EU (which I know is longer than the US due to the vast differences in average emissions per vehicle between the two continents).

For most of the world, the GP is correct. Driving whatever car you have will always be more environmentally friendly than buying a new EV. Reduce and reuse are environmental cornerstones for a reason.

cogman10•7m ago
People keep their cars for longer than 2 to 4 years and an EV sold in 2 to 4 years will likely be driven by someone else.

Which is why I put a used EV as being better for the environment vs a new one.

But both will be better for the environment in their lifetime than keeping a used ICE on the road.

It's more economical to keep your current car until it starts seeing major mechanical issues. However, environmentally an EV will (almost) always beat an ICE, the sooner you get one the better. Especially in a place like the EU where you can get even more environmentally friendly EVs due to the lower amounts of driving. You can, for example, grab the BYD seagull which has a 30kWh battery pack. That alone significantly reduces the new EV environmental impact beyond what some of the older numbers would have shown.

hdgvhicv•9m ago
My small car does 3,000 miles a year, or 300 litres of petrol a year, or about 1 ton of co2 a year.

How many co2 tons are generated in making a new Nissan leaf?

jsight•13m ago
Plenty of people that can afford them and that would likely benefit are not buying them because of preference.

In many cases, this is rational. Yeah, a used Model 3 with a great rate plan is probably worth it as a commuter, but what if you are an outlier? Even a low battery failure rate can be a risk, and extended warranties are expensive.

But also, some of it is irrational, as the FB comments effectively feed many false fear driven narratives.

anonu•51m ago
> How long do electric car batteries last?

The article never answers the question. But if you assume 70% end-of-life threshold with 2.3% loss per year - then we're looking at 13 years.

criley2•40m ago
Why is 70% a end of life threshold? Considering that most major models are sold with configurations where the entry level begins under 70% compared to the "Long Range" model, clearly 70% is a perfectly fine level of battery for some users.

I myself have a 11 year old Nissan Leaf with pretty significant battery degradation (the guessometer says 70 mi range but I wouldn't count on more than 35-40) and it's fine for probably 95% of my driving.

If I were to buy an electric car with 300-350 miles of range today, I could easily see myself finding a ton of value in it in 20 or even 30 years. It's still more range than my current one! Lol.

nritchie•40m ago
Hopefully, in coming years, we will see more practically designed EVs that are more affordable. A practical car doesn't need neck-snapping acceleration, every bell-and-whistle and room for a family of six with a dog. I'd like to believe that as batteries cost drop, the incentive to justify the extra cost will drop. Then we can get back to "just basic transportation" rather than a luxury product for the rich. While $31k isn't exactly cheap, the base new Leaf is heading the right direction.
dangus•26m ago
At this point most EVs are exactly the way you describe and Tesla is an outlier.

Look at Hyundai/Kia’s lineup. The Niro, EV6, and EV9 are essentially the three major segments of American car preferences. They aren’t particularly fast or exotic.

They don’t really cost a whole lot more to buy/own than alternatives in the same segment especially on a monthly payment or buying one used, they just aren’t chosen at a high rate compared to gas powered alternatives.

Tesla just used the neck-snapping acceleration to market EVs by cool factor rather than by economics. And that was a smart idea to get people in showrooms.

boplicity•18m ago
Affordable EVs exist and are widely available in some countries. They're effectively banned in North America, though.
zdragnar•5m ago
This has always been true of gas vehicles as well. They're banned for not having some safety feature or otherwise complying with FMVSS or some other regularity body, not because they are "affordable".
oklahomasports•10m ago
81% of original capacity for many cars means when driving at highway speeds you will get like 250 miles or less range per charge. Still dramatically less than gas cars.
