Where are the batteries coming from?
Maybe it’s crazy idea but… China?
No need to be a smartass, I’m genuinely curious if they are importing batteries from somewhere else
And if China, where are the mines so I can check out the environmental destruction on satellite imagery
I mean it’s pretty common knowledge that China is the biggest rare earth metals producer in the world. It’s also well known that the batteries they produces are pretty bad for environment. And it’s also known that Chinese EVs are still better for climate change than oil. It’s all been covered many many times. Are you following any news?
The batteries are also recyclable, which should make the equation even simpler.
I mean it’s not that simple because you can’t recycle the entire battery
The number I’m seeing is up to 95% recyclable. That’s preeetttty much the entire battery. Are you talking about something else?
I never said it’s not better than oil, I never even mentioned climate change. Lemmy sucks, you guys are dicks, like fuck me for asking a question lol
Worse community than reddit, fuck you guys. This is why lemmy is never going to grow. Wonder why comment sections are dead? You are the problem.
To answer your question, yeah I follow news, that’s why I assume China is probably strip mining for metals in the worst way possible. Of course mass producing batteries is going to be environmentally destructive. So where are the mines?
The mines are also in China. What’s your point? Why are you asking obvious question?
China is massive, where in China? Why can’t you just answer my question instead of being a dick?
You will have to look that up I guess.
I’m genuinely curious
No you’re not. Nobody says that unless they’re trolling.
Also worth mentioning that it’s not just cars, but public transit and city planning.
It’s worth noting that this is not being done for environmental reasons (more half of all coal pollution comes from China), but for strategic reasons as China has limited access to oil near it’s borders.
Car engines are immensely inefficient and car charging is a load that’s easy to load-balance for renewables (dynamic pricing see: Tesla)
Yup! EVs and renewables are broadly good things. Just wanted to give some added perspective :)
An EV running on a coal fired grid still has less emissions that a prius. Facts dont care about your feelings.
A Prius will definitely pollute less than the typical SUV electric cars on a coal grid.
Cause:
- Efficiency of coal power plant and all losses are as bad as ICE cars. The EVs do thermal->mechanical->electrical->grid->battery->wheels and if you count them all up, is not better than an EV
- Prius is designed for low drag unlike an SUV
- Prius had regenerative braking like an EV
But just the numbers:
- Prius is rated at 94g/kg
- Coal 950g/kwh
- Volvo c40 0.2kwh/km or 190g/km even without losses
I took Volvo cause they published a report with a good compare ev and ICE https://www.volvocars.com/images/v/-/media/market-assets/intl/applications/dotcom/pdf/c40/volvo-c40-recharge-lca-report.pdf
Even with the current EU energy mix, it takes 77’000 km to be better than ICE, so arguably better. On coal electricity, they are worse. And this is comparing equally sized cars, a Prius will do better.
Regardless of the accuracy of your numbers - If you fix the ICE cars as they wear out, replacing them with BEV as the energy grid retires coal plants or goes to a higher percentage of renewables, they get cleaner. ICE cars will be as dirty tomorrow as they are today.
That is true. I do think we should retire pure ICE cars as soon as possible. If you need to do long distances, a hybrid that could be converted might be a good intermediate solution. If you only need a car sporadically, a car sharing platform with electric cars is a good solution. These already exist in big eu cities. Ofc good and adorable public transport is nr 1.
Decreasing the amount of cars would decrease emissions short and long term more than the current shift to EV and would make shifting easier as there are just fewer to replace.
Could you please run us through your maths? I’m legit curious.
An ICE is only, at most, 35% efficient. In contrast to lithium batteries and electric motors, which is more like 90% efficient. Electricity produced from the dirtiest coal plants that exist, used in an EV, is more efficient and, thus, more environmentally conscious, than burning gasoline in an ICE.
The coal plants are not 100% efficient though. In fact they’re probably in the realm of 40%
Yup, and that’s ignoring the loss in transforming and transporting the energy across the grid, and in the chemistry of the battery itself through charges and discharges. Energy density of batteries is also a fraction of that of petrol, so every EV is also carrying around a lot of extra weight.
Coal power plant efficiency is less than 40%. You’d also not get 90% of the outlet on the wheels. There is also a lot of loss on the grid, but there is also on the production of fuel. The two pollute almost the same.
Burning coal however is a lot worse for the air quality.
It’s the put the pollution somewhere else policy so that cities are more liveable. It was hurting China’s reputation and too many rich Chinese were going overseas and siphoning away the economy (and still are).
I don’t know if their statement is universally true, but the EPA’s fuel economy / total emissions calculator seems to show it for what I’ve put in. You can put in a Prius or random EV and see how they compare.

What a ridiculous distinction. Do you really think this narrative difference in motivation is noteworthy? What is scarcity if not an environmental consideration? What is lack of sustainability if not an environmental consideration?
It’s being done because it leads to a sustainable equilibrium of their social system. Whether that meets your standards of rhetorical “intentionality” to meet the criteria for “environmentalism” is meaningless.
Is it worth mentioning? Why?
Just wanted to add some perspective. There’s a narrative lately that China is a champion of the green movement, which is absurd
Pretty reasonable narrative tbh. China’s CO2 emmissions plateleued last month and have even started to fall, and they’re targeting zero emissions by 2060. They’ve also started spearheading cleaner energy this month with the first 4th gen nuclear reactor.
And of course the news in this post.
It’s no less absurd than the opposite narrative, that China is some kind of climate villain.
The reality is China is on the right track, but not there yet. I’m somewhat optimistic.
I mean, that’s a pretty good reason. I’m not too concerned why they do a good thing, as long as it’s done.
Electric cars aren’t a “good thing” though.
I assume you mean that they’re not a positive for our environment, even so they’re much better for our local environment, which is still one better than petrol and diesel cars imo.
You might get up votes if you accompanied a controversial opinion with a reasoned argument. However, making only broad, unsubstantiated statements is a waste of bandwidth and everyone’s time.

Ultimately I agree that they should include the argument, but adding a reasoned argument has very little affect on the use of the vote buttons as “agree/disagree.”
China is also the world leader in sustainable public transportation solutions
They’re a “better than ICE cars” thing. I’ll take whatever improvements I can get
Why not? This has been researched many times, and the results are consistently that it is a good thing already, and getting better, in regards to overall co2 produced
They’re also far more efficient than fuel cell too
China’s EV revolution showcases the power that state actors have when an industry is a matter of national security.
China has marginal domestic O&G reserves, so moving off of O&G is incredibly important for Chinese interests.
All EVs still require coal or oil for the electricity. And that doesn’t even factor in mining for the metals to make these things.
EV are okay but they’re not a solution to our resource consumption problem.
And since the oil and gas companies in China are nationalized, they will follow along with the government’s plans rather than obstruct or bribe their way as with for-profit private oil and gas companies in many western countries.
Woah hold the phone, you’re telling me there’s a way to build society OTHER than by explicitly rewarding greed and exploitation‽
It is a similar story in Saudi Arabia and many Arab countries. The oil and gas is nationally owned, and the revenues are being used to finance a massive welfare state as well as the transition away from fossil fuels.
I think saudi Arabia moving away from fossil fuels isnt really true considering their (ODSP) is a plan to hook the 3rd world on said fossil fuels.
Developing countries need cheap energy
So, solar and wind? Both cheaper than fossil fuels at this point.
But if we were really serious about sustainability, wouldnt it be better to not get more of the world hooked and fossil fuels in that way.
Which is not me saying everyone should be driving EVs, because fuck cars.
Oil isn’t just used for cars. A lot of countries use diesel trains on routes where electrification isn’t feasible for various reasons. Here’s a modern diesel train https://youtu.be/tFoljwX6o90
They also don’t seem to have many standards either. Specs and reviews I’ve seen seem to jump generations within a few months. I think my favorite ridiculous spec was the ability to use two fast chargers (one on either side of the car since it has two plugs) to pump some 300 miles in 5-10 minutes. It’s wild to read about the stuff they’re doing.
As a Saudi I’m happy with this development. The future of cars is electric.
Now do coal
“Every car you start driving with electricity, you’re not driving with oil,” said Robert Brecha, a professor of sustainability at the University of Dayton in Ohio
The journalist has to have a personal grudge against him. That d’oh quotation makes him seem dumber than my dog.
And it’s not even necessarily true: it takes a certain mileage to offset the extra CO2 that an electric vehicle requires for its manufacturing (mostly batteries), which directly depends on the grid’s carbon intensity. If you recharge your EV from a coal or oil plant, you are still burning coal and oil.
But at what cost?
