Everyone knows that electric vehicles are supposed to be better for the planet than gas cars. That’s the driving reason behind a global effort to transition toward batteries.
But what about the harms caused by mining for battery minerals? And coal-fired power plants for the electricity to charge the cars? And battery waste? Is it really true that EVs are better?
The answer is yes. But Americans are growing less convinced.
The net benefits of EVs have been frequently fact-checked, including by NPR. "No technology is perfect, but the electric vehicles are going to offer a significant benefit as compared to the internal combustion engine vehicles," Jessika Trancik, a professor at the Massachusetts Institute of Technology, told NPR this spring.
It’s important to ask these questions about EVs’ hidden costs, Trancik says. But they have been answered “exhaustively” — her word — and a widerange of organizations have confirmed that EVs still beat gas.
We’re going to run the country into the ground because we have such a large group of people being totally fine with (or even encouraging) their lack of education and the ability to reason properly. They’re just proud to be “against” something together, they don’t even care what it is they’re against.
There are already EV battery recycling plants springing up now that there are enough used EVs to warrant them, there wasn’t much point building them when there weren’t any battery packs to process.
The renewable energy switch is already happening, because even without subsidies they’re still cheaper.
But no… gotta get out there and roll coal.
North American auto has lost its mind and handed over any chance at being top-tier in the future. Seems game over to me. Canada is joining in on the 100% tariff game and I’m furious that my government will, this late in the game, try and protect an industry that gambled with the oil and gas industry and lost (not to mention their compete fall into profiteering in five to six digit major life purchases) by passing costs of avoiding Elon and subpar selection onto consumers.
I hope the industry wakes up and goes hard for competitiveness in EVs and stops waiting for elections to decide if climate change is real or if the economy will be affected by their decisions. To stop waiting for elections to decide if people want EVs. To allow manufacturing to flourish regardless of who’s fighting for the rights to our money while we briefly have it.
And to your point yeah - just like Asimov said:
There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.
Be sure to call a few government reps and speak your mind. Try to do it by asking questions. If you can turn a few aides against the system it can have a snowball effect bc those are people who are young and passionate about politics
100 percent.
The reality about the whole “write your congressperson” mentality, at least in Canada, our elected officials (Members of Parliament for our Federal gov, Members of Provincial Parliament for our Provincial gov) are engaged in rampant tribalism. Unless your wish is parroted by a significant portion of the population AND is in line with the goals of the party, your political engagement is worth nothing. Sure, you’ll get a response back, but it’ll either be Conservative culture warrior validation or Liberal boilerplate lip service assuring you that they value your input. Our Federal government is run by the Liberal party who have devised an immigration scam to increase the value of their real estate portfolios and literally have eschewed all other issues in our country, and our Provincial governments are arguing over beer and healthcare. There is no left of center representation in Canada, and most people seem on board with the tariffs.
I would agree that writing does nothing, they probably throw it away without even reading it, but talking to real people who actually want to improve things (like political assistants) can make a difference.
I live in Virginia and the other day I saw a Tesla with a custom license plate for friends of coal. like I don’t even…
I must admit this is a big-brain move — being for electric cars in order to have more coal-fired plants rather than burning gasoline.
Even a coal burning EV emits less carbon than a gasoline car. The payback threshold may increase uncomfortably though. A while back I read something doing that analysis per US state. I believe the threshold ranges from 2 year in states with cleaner energy, up to 14 in coal burning West Virginia and Wyoming
I just find it funny. It’s perfectly logical for someone who really cares about burning more coal to drive an electric car, but I’ve never seen anyone make that connection before. It’s like… I don’t know. A vegan lobbying against lactase pills?
And 14 years isn’t really feasible given battery decay.
Eh, maybe.
If you want to age something artificially, you run it through cycles of use very quickly. To age a wood joint, you run it through cycles of high heat and humidity and then drop it back down to cold and dry, and do it as fast as you can for weeks or months. Aging a CPU is similar; heat it up and then cool it down. For batteries, you hit them with a lot of charge and discharge cycles.
This artificial process may, if anything, be harsher than any real world use. So there’s reason to think that manufacturer estimates are pessimistic.
This does appear to be the case; modern EVs have been around long enough now that we can get some real world data, and batteries are lasting longer than expected: https://www.pcmag.com/news/how-long-do-ev-batteries-last-study-says-longer-than-you-think
“There are two states that have such shitty electricity production systems that it may take more than the lifetime of an electric car for the carbon emissions to break even. That’s how terrible electric cars are!”
🙄
But the coal is cleaned, so it’s better to burn it for electricity. Duh 🙄
Wasn’t that what Desantis did, put a coal sticker on his Tesla? Then had dealerships write up a bill to restrict people from purchasing vehicles directly from manufactures without going through a dealership, keeping the costs higher for the people. The bill had an exemption for certain vehicles… Like the Tesla he bought.
That feels like they’re trolling or making fun of themselves a bit. I know a few people in Kentucky with EVs and they also have “friends of coal” plates.
AFAIK it’s the only way to get a black plate hence why they do it. Looks cleaner on darker cars.
This is the bottom line. We all know who these morons are and they’re never going to care what actual repercussions are for their actions. They think it is funny to “own the libs” no matter what the issue may be. If a left-leaning person advocates for one thing, their automatic reaction is to oppose it without question.
It’s truly scary to look around (especially in red states) and to know a good percentage of those around you are that dumb.
I don’t consider myself intelligent. One of the scariest moments of my adult life was realizing I’m above average intelligence, maybe by a decent margin.
They have guns too.
The end of life battery recycling has been the #1 thing I’ve been looking at. Glad to see they aren’t going to landfill.
Battery upcycling is also becoming a thing. If an old battery is not fit for a car anymore it can still be useful in other contexts; like you could convert it into a battery for home or grid storage with minimal processing.
edit: rephrased to remove double negative
I’m curious to know what you’ve learned. Would you care to share?
If you’ve been looking at it, then perhaps you’ve seen this:
EV Batteries Can Outlast A Vehicle’s Lifetime With Minimal Degradation, Study Finds https://insideevs.com/news/733987/ev-batteries-outlast-vehicle-degradation-study/
““Batteries in the latest EV models will comfortably outlast the usable life of the vehicle and will likely not need to be replaced.” That’s what David Savage, Vice President for the UK and Ireland at Geotab said in the company’s latest study that looked at how EV batteries degrade over time.”
But if not, the article, and research it’s based on is worth a gander. EVs require a whole lot less maintenance, too, as it turns.
So far, the biggest problem with battery recycling is that not enough of it is done locally. Depleted batteries are being shipped to China for recycling.
https://www.npr.org/2024/06/27/nx-s1-5019454/ev-battery-recycling-us
But things are improving here, so that’s good!
Ideally what I’d like to see are large, regional, recycling centers and that’s just not a thing yet. I’d say a minimum of 6, 2 in the West, 2 in the East and 2 in the center of the country.
While I was poking around I found this, on Lithium Ion battery recycling:
Pathway decisions for reuse and recycling of retired lithium-ion batteries considering economic and environmental functions https://www.nature.com/articles/s41467-024-52030-0
Abstract Reuse and recycling of retired electric vehicle (EV) batteries offer a sustainable waste management approach but face decision-making challenges. Based on the process-based life cycle assessment method, we present a strategy to optimize pathways of retired battery treatments economically and environmentally. The strategy is applied to various reuse scenarios with capacity configurations, including energy storage systems, communication base stations, and low-speed vehicles. Hydrometallurgical, pyrometallurgical, and direct recycling considering battery residual values are evaluated at the end-of-life stage. For the optimized pathway, lithium iron phosphate (LFP) batteries improve profits by 58% and reduce emissions by 18% compared to hydrometallurgical recycling without reuse. Lithium nickel manganese cobalt oxide (NMC) batteries boost profit by 19% and reduce emissions by 18%. Despite NMC batteries exhibiting higher immediate recycling returns, LFP batteries provide superior long-term benefits through reuse before recycling. Our strategy features an accessible evaluation framework for pinpointing optimal pathways of retired EV batteries.
Ideally what I’d like to see are large, regional, recycling centers and that’s just not a thing yet. I’d say a minimum of 6, 2 in the West, 2 in the East and 2 in the center of the country.
One of the challenges is, ironically, there aren’t enough dead batteries to economically support multiple large domestic battery recyclers. Batteries aren’t failing enough.
The problem with that model is that when they all start failing it will be a crisis without the infrastructure to solve for it.
What crisis are you foreseeing? It is unlikely its going to be an avalanche of millions of batteries failing at once needing processing. Wear and tear will spread final failure over a long time horizon.
Piles of spent batteries stacking up leaking heavy metals into the envirionment without a large scale plan to deal with them.
A single EV uses a 1,000 pound battery pack (on average):
https://blog.evbox.com/ev-battery-weight
That’s a LOT to properly dispose of. x 3.3 million EVs in use in the US?
https://www.edmunds.com/electric-car/articles/how-many-electric-cars-in-us.html
3.3 BILLION pounds of future battery waste. We need to plan for proper recycling now.
That’s because there’s not yet enough EV installed base to drive demand for recycled batteries.
Is Redwood Materials shipping things overseas? They seem to be the big car battery recycler the automakers are signing up with.
They have a very good map on the production end, showing where metals are sourced and refined, then cathodes produced in Japan and sent over, but I’m not seeing anything similar on the recycling side.

By insisting on perfect, you are preventing incremental change.
You can buy an EV and have a country invest in transit. These do not need to be exclusive things
Sure. Or I can drive my old car very little and be pissed my country subsidizes a clearly inferior solution just to save the car industry instead of subsidizing way more efficient and environmentally friendly mass transit.
Edit- I think we’re agreeing now that I look at your other comments but I’ll leave this.
Incremental change would have been fine in the 1970s when the world should have instituted it, including incrementally reducing industry to absolute necessities like medical products, and individual developed world quality of life, to find homesotasis with our only habitat.
Now it’s smash the factories today, and accept the hundreds of millions dead breaking those poisonous supply chains, including possibly ourselves, for humanity to have any non-nightmarish future on a planet we terraformed to be hostile towards Human life for the next couple million yers.
But having absolutely failed to institute incremental change half a century ago despite warning, and absolutely failing to take drastic action now that we are just beginning to feel our irreversible fine work, our species clearly and resolutely chooses no future/nightmare susbsistance future, or at the very least there wouldn’t be a pop figure/pointless plastic crap factory left standing in the world. 🔥🤷♂️🔥
What I find the most ridiculous is what we’re doing: resolutely choosing death by actions, while still strangely preaching hope for a future. WuT a weird fucking species we were.
Automotive tires are a leading source of microplastics so EVs aren’t exactly a darling angel
Could we not just make tires out of a different material?
Yes and no.
Yes it’s possible. No it’s not scalable or affordable.
Synthetic plastics (all plastics for the purposes of this conversation) are byproducts of the petroleum industry. They’re making gas out of oil and are left over with plastic precursors so those get made into something and everyone wins* because the materials are basically free.
Last I looked we were creeping up on two billion tires a year.
it’s not just capitalism, the US is a very spread out place compared to most other countries. if you want everyone to use mass transit you’re asking them to either 1) move into the city for similar commute times, or 2) spend an inordinate amount of time riding busses around the suburbs for the same distance commute. Neither are good solutions.
And also we have solved the “getting to work” debate with teleconferencing. why should we need cars or an even bigger mass transit system when most people can simply work from home?
if you want everyone to use mass transit
That’s the point, nobody wants to move people in the middle of nowhere to buses. Everyone wants these people to move to buses:
That’s like a half-full train’s worth of people if they single-seat, which they do, or 5-10 buses.
Imagine how cooler the place would be if that 16 lane road would be a 2 lane train track.
Eh there are plenty of places that have less population density than the US but they do just fine with transit. It might be true that most US cities are poorly designed for transit, but the density isn’t a the reason.
Someone has to see Not Just Bikes. Capitalism was the driver to the sub-urbanization process made after WW2 in the US, as a national economic policy to orient growth around building detached houses, private cars and suburban infrastructure (and secondary security considerations of reducing losses and damage in case of nuclear bombs in cities). The US was not a '‘very spread out’ place before WW2 (i.e. for the vast majority of its history), in fact cities like San Francisco were world leaders in mass transit, and trains were the axis of transportation of both people and goods (even existing suburbs were connected to trains, in whatever shape and size they come). The us cities spent and spend an enormous amount of money and debt to pay for all the road infrastructure, that even neoliberals say it’s not economically sustainable, and that money can also be better used paying for higher quality mass transit, not the tertiary thought they give it now (horrible buses that stay in traffic with the cars for the poor people that can not afford a car). Most people do not work remote all the time, even flexible / hybrid workers need to transport themselves some trips per week. Not to mention that full remote work may over time trickle to foreign countries that do the service cheaper, and the work remaining onshore is work that the owners need-want at least hybrid or on site workers.
The US was not a '‘very spread out’ place before WW2
no kidding, the population was also like a third of what it is now.

yeah, mass transit within cities is a great idea and should be used as much as possible. I am not shitting on the general idea of mass transit. what I’m saying is, in the context of a practical daily commute, mass transit only works to a point, and a LOT of people live beyond that point.
Most people do not work remote all the time, even flexible / hybrid workers need to transport themselves some trips per week.
again, I’m not saying mass transit should never be used. what is the cost:benefit for the infrastructure to cover out to the suburbs? how much time is added to very long trips, and are people willing to deal with that?
Public transportation is even better yet
And when we actually get that going I’ll stop making sure I always have a car available.
yay for privilege I guess but we can’t all do that
Can’t all use public transportation? I don’t know what you read up there, but I’m in favor of it, I just don’t think we’re ever going to do it. We’ll bring back corporate owned worker’s barracks with corporate scrip before we actually give ourselves good public transportation.
No. The other thing.
Ah okay.
For inner city folk yes.
The US used to have an incredibly comprehensive rail network, combined with street cars in every town. This “public transit is only for cities” nonsense is pro car propaganda.
I used to live outside a town of 3,000 people. Prior to the 1950s it had a trolley that would take you to the 15 miles to the nearest city, and from there you could catch a train to go pretty much anywhere.
You can still have public transit/trains on suburban areas. See Germany or the Netherlands.
Or Japan, or China, or South Korea, or Italy, or Argentina, or Lancaster PA, or parts of New Jersey even. Fuck man so many places have public transit.
How I’m imagining public transportation in Lancaster, PA:
I mean close but instead think a fleet of like 20 bus routes that spread out in every direction for miles and miles into suburbs and farmland. And the buses have real time GPS tracking.
But otherwise very similar.
Japan beats everyone.
Its not a “you can” problem. Its a “we don’t” problem. I cannot get to work on time (7am) using the only public transport we have (bus) in a county with a million people. Also would take about 1.5hrs longer than by car. to be 15m late (assuming the bus is on time) every day. puts it around 4 hours travel to/from work, so work takes up ~12 hours of your day.
It sucks that this is so commonly the case. I’ve had times when I’ve been able to commute by bus to work and it genuinely makes the trip so much more pleasant - even if it takes thirty minutes longer (as it did in my last job where I did it) the ability to be on my phone for the whole trip was so nice I’d go back in an instant if I could.
The trip length is certainly an issue but bosses in the US need to be more on board their workers arriving when the bus system can reasonably get them there instead of demanding a ~25,000 dollar investment just to get to work.
Saw a rural bus system working perfectly fine in South America. If they can figure it out, so can we.
In Japan, taxes collected on the Tokyo metro (which is privately owned but heavily regulated) help subsidize a thousand little suburban and rural bus and rail lines. It’s not rocket science, even in the US a similar scheme is employed by the Post Office to ensure everyone’s mail costs the same to the consumer.
Even just taxes. I pay taxes. I’d like to breathe less shit from all the commuters and have all the people I depend on at their work. This aversion to taxes in the US is terminal unless we get rid of it.
can you really blame us?
let me run through the last 8 years of American history with four words, “we were lied to”. doesn’t matter from whom, doesn’t matter what. we’re constantly being lied to. truth is, it’s been true for longer than 8 years, but the last 8 have been especially transparent.
we’re learning that the upper echelon only trusts the American public to do three things; consume, produce, and die. if you can’t even do that for them, you’re removed as an undesirable.
so yeah, trust in the system is broken. it’s going to take at least a generation or two just to repair it ** if they work on it**.
I can’t fault anyone who’s untrusting of a system that continuously covers lie after lie with more lies.
8 Years?
How long did fossil fuel companies know about climate change?
How long did the fuel industry know about the effects of leaded petrol?
How long did cigarette companies know about links to cancer?
How long did pharma companies know about opioid addiction risk?
How long did social networking companies know about psychological manipulation?
How long did the sugar lobby know about their links to diabetes and obesity?
How long did the manufacturing companies know about PFAS and microplastics?I would say you have always been lied to.
Your forgot that plastic manufacturing knew it wasn’t recycled or recyclable.
I can’t fault anyone who’s untrusting of a system that continuously covers lie after lie with more lies
I can and will. Learn some basic critical thinking skills and apply them. Throwing your hands up and ranting about how “the system is broken” is mopey teenager shit.
Things are far more complicated than your whiny rant. They world is shades of gray rather than the simplistic “bad guy in black / good guy in white” situation that you characterize it as.
You overestimate the general populations intelligence.
Very true.
Lololol, what a fucking worthless right wing rant
lulz jokes on you.
Fuck Trump, fuck republicans.
The only valid criticisms of EV’s are:
-
They’re harder to extinguish than a gas car if they end up catching on fire.
-
They don’t really solve any of the major issues with car based infrastructure.
-
Tesla is a shit show because of that damn muskrat which pushes a lot of people away from EV’s in general.
They are heavier and accelerate faster than an equivalent ICE vehicle on the same frame, and so result in more pedestrian fatalities.
They are heavier and accelerate faster than an equivalent ICE vehicle on the same frame, and so result in more pedestrian fatalities.
I lump that in with part of the major problems of car based infrastructure but that’s still fair to point out.
All else being equal
They’re harder to extinguish than a gas car if they end up catching on fire.
Yeah that is gonna be a bigger problem than most people imagined.
To be fair, no consumer vehicles have 900 kWh batteries haha.
My firefighter neighbour told me that the procedure now is just to let them burn, like they do with gasoline fires. They make sure it doesn’t spread, but they won’t try to extinguish it because it’d take 10-12 hours and thousands of gallons. By just letting it burn they’re done in an hour with a few hundred gallons.
They don’t steal a lot of data too? Or this privacy nightmare affected gas car too?
It’s an issue in newer cars in general.
-
An even larger portion of America can’t afford them, so it doesn’t even matter.
Thank you. I can’t even afford a base model Corolla and used cars prices are through the roof. I might have to buy a paraglider or something.
Check out auctions, feds and locals are always dumping cars. They can be a decent bit cheaper than dealerships with better maintenance and lower prices, talking SUV with sub 20,000 miles on it for $2,000 cheap.
Removed by mod
Over the longterm, and they also require a lot less maintenance because they don’t have to deal with mini-explosions from combustion generating excess heat and stress. The problem is in the battery, and the industry hasn’t even scratched the surface for solutions.
I see trucks carrying butane tanks all the time, where are the trucks carrying EV battery replacements? There aren’t because the industry wants to charge extra for fixed installation ones depending on capacity and charging capacity and there is absolutely no profit incentive that offsets other losses to standardize battery systems in a way they can be easily extensible or replaceable.
I see trucks carrying butane tanks all the time
That’s not the equivalent to battery replacements but to the power grid, which of course is yet another win for EV (since clearly distributing the energy source for vehicles over the power grid is safer and more environmentally friendly than needing huge trucks to carry it).
(I’d say battery replacements are closest to motor replacements in gas cars in terms of costs and effort. What about the environmental impact? -> That’s why it’s so costly. To mitigate environmental impact.)
Battery replacements really are not difficult, I’d seriously recommend not imagining obstacles where there are not.
Without special installations, charging takes several hours instead of a quicker battery swap (which you could take with you as extra weight). DC chargers cannot even be installed at how home due to their requirement. Swappable batteries are possible and would make EV cars adaptable to new and different battery technology, they are just not designed that way.
Some, like the XBus, talked about allowing it, and it is perfectly possible, it just isn’t going to come out of traditional car manufacturers who had to be dragged to develop anything EV or manufacturers like Tesla who want to make range a subscription feature. Let’s not even go into EV range extension trailer systems, which would be as effortless as swapping trailers.
So, just so you know, the average EV battery weighs 1000lbs, and some all the way up to 2000lbs in something like the EV hummer. (Unnecessary I know). The cost to have a battery in an EV replaced currently sits around $5000 to $15000 off of warranty. So there are definitely obstacles. Along with letting the general public fry themselves trying to hook up a 400v battery. You’re not dealing with AA batteries. Battery technology is far away from something able to swap out yourself with the ease you may be thinking of.
So, just so you know, you can purchase 96V batteries that weigh less than 30 kg and can be connected in series to provide well over 400V, and if you want more range you can install bigger ones. EV ones weight that much because of the range, which is less of a factor if they can be swapped. They are made up of cells which are individually far below 400v, and there are standardized Anderson connectors that can safely connect and disconnect +600V and are used all the time. The cost of a battery is a non-factor is you are just renting them like you are sort of expected to do with butane tanks. 50V is the limit where you usually begin receiving a shock at, but 400V is not really considered high voltage and can be easily handled with the proper connectors and failsafes, like not swapping with a load.
It’s better than letting the general public fry themselves trying to fuel their cars with an ignitable combustible.You are not dealing with rubbing alcohol. /wildscaremongering
Battery technology is something I’m constantly swapping out for myself with ease, but that’s because I don’t make my own mental blocks. So do owners who retrofit gas cars to EVs. My goal is to retrofit an older EV car so that I don’t have to pay around $5000 to $15000 of overpriced proprietary batteries. It is a long-term goal, but be happy, it is not one that could be shared because the only way to do so would be in a society open to it.
Please let me know how that goes for you and when I can purchase one that allows me to travel 500 kilometres in -25°C without disabling the vehicle mid trip in that mentioned temperature.
You mean for your highly specialized need that the majority of potential EV drivers currently turned off by the step costs don’t need? Sure, let me just make a note, since the solution is scalable, even working in the energy demand of a heater.
Ah yes, I am the only person on the planet who has a need to travel occasionally to a larger city during a normal winter. Got it!
This is already the present; we have power tools that already swap batteries on the fly. The problem is more complex as you add batteries and charge, but not insurmountable. I see the first application in truck fleets.
The problem is that in those cases it is still a proprietary market.
Where are the trucks carrying the replacement petrol tanks for ICE cars?
You can get them at Amazon: https://www.amazon.com/s?k=gas+tank
You aren’t making a point if you are trying to equate the distribution network for gas, which is so ubiquitous that there is no need for the sort of trucks that distribute butane tanks to EV batteries, which require specialized facilities for fast charging, which also deteriorates batteries faster, or otherwise take half a day of charging. EV battery swapping bans already exist for things like scooter rentals.
There are already standarized sizes, voltages, and ports using in autocaravans which could be connected in series ideally through BMS to provide the voltages EV cars would need and would even be simpler through already prepped trailer systems. Four 96V batteries (can go up to six) in series connected safely through Andersen connectors would be enough for a basic EV car, that’s less than 30kg LiFePO4 each, making it swappable on the spot, less dangerous than lithium, and open to a large market of providers.
Put them in a sealed room with a gas engine running and you’ll see how fast they realize that they’re cleaner
Fair, but the first rebuttal is going to be “go into a sealed room with a coal fire burning”
… how is that an argument?
The argument is that all you’re doing is moving the carbon emissions from the car directly in your vicinity to the coal-fired power plant a long distance away. Move that same coal-fired power plant into the sealed room, and suddenly it’s no longer far away, and the “unclean” nature of the electric car, so the thought process goes, becomes obvious.
That’s the thought process if you just stop thinking when you get to a point that reaffirms one’s biases. If you continue down that train of thought you’d realize it’s a lot easier to regulate and monitor the emissions of a coal power plant than it is every single car on the road. Plus you don’t need to use coal to make electricity.
I’d happily hang out in a sealed room with a nuclear reactor.
Isn’t the whole point that the gas engine equivalent is just in somebody else’s room though?
In any case, I’ll take whatever partial climate wins we can get.
Solar, wind, and nuclear energy: are we a joke to you?
Even if we assume all the electricity is coming from carbon sources (there’s no need for any of it to be carbon sources) it’s still more efficient because power plants are way better at turning that chemical energy into electricity. Even with the losses in the lines, charging, and in your motors, electric cars are still significantly more efficient on a mile per kg CO2 basis than gas cars. Throw some solar panels on your roof and they become essentially carbonless.
It’s really easy to understand why too. You completely waste most of the heat energy you produce in IC engines. They’re incredibly inefficient and always will be.
Yeah, what is it, 70% energy lost to heat in an ICE?
Genuine question - are EVs better for the environment if the main source of electricity of my country is coal based? Most of the coal plants are pretty old too…
Yes, whether your electric plant is coal, natural gas, or honestly even if it was diesel. Larger engines are more efficient than smaller ones. It’s been a long time since I broke down the math over 10 years so my information is probably wildly out of date but even 10 years ago when you broke down the math charging an EV from a fossil fuel plant of any kind was still ultimately more efficient than a gas car in the long term.
Couple that with the ability of many EV now to also act as a battery for your house and that just goes wildly into the EVs favor if you utilize that for peak demand offset. Which many people could do easily even if it meant not having their battery fully charged in the morning when they go to leave for work because let’s face it very few people drive more than 60 miles full round trip in a day so even with their battery at say half they would have more than enough for their whole day plus extra.
Do we actually have hard data to determine if coal power delivering your electricity is indeed cleaner than what an ICE emits?
It’s pretty simple really if you look at commuter traffic. Each stopped electric vehicle does nothing while stopped.
Aside from heating or cooling the occupants, that is.
Yeah, compare 500w heating to 30kw starts. But it does matter if you’re gonna be there eternally for 8 hours or something. Heating is inefficient when you’re not doing something else with the water before hand.
Somehow instead of having a GPS app tracking traffic to top off the batteries before you get there, I much rather have an app try to convince me to park my car, take a bus and try again tomorrow.
Yes the MIT link covers coal. At worst it’s on par with gas cars. They get better as the energy source mix does but they aren’t worse than gas powered cars.
Yes you can get the emissions per equivalent kilowatt hour of both. Especially since there are many electric generators that are just using a car engine. And it’s a known fact that at least in terms of energy generation larger motors a better conversion rate of fuel to electricity and power plant Motors are quite a bit larger than most cars. Unfortunately I only really have my phone available to me at the moment and I’m a little busy so I don’t have time for much more than these quick replies but over the next couple days if I get a moment I will come reply to this again after finding the actual figures if you haven’t already found them yourself which please do reply to this with them if you find them
The “break even” point is still somewhere around 150k miles for big batteries (above 75 kWh). And while there are many EVs that have 200k on their first battery, that isn’t necessarily the status quo for most of them. A simple lump of Aluminum or Cast Iron takes a lot less energy to make and can even be produced completely renewable If you factor in synthetic fuels, things look even more grey - especially with algae, there can be huge benefits growing algae in sea water (see the Arctic Algal Boom and the connected pytho plankton growth). BEVs are not “THE” answer, they are one answer to specific questions.
Not only that, the issus (environmental, child labour, etc) with rare earth elements are still not solved and the environmental damages through lithium mining are not something to just sweep under the rug.
Or maybe 13,500 miles. But what’s a few zeros between friends?
Argonne assumes the batteries are produced with renewables AND they assume EVs are going to be charged over the day, when most of the renewable energy is “present”. Most BEVs are charged over night, where only Hydro or Geothermal makes power. Meaning, the Co2 footprint grows exponentially, because at night most of the power is made with fossile fuels - a kWh easily can have a rucksack of over 700 gr/kWh of Co2. But hey, what’s a few assumptions here or there in favour of either side, huh? Oh and go talk to China about them producing the batteries “environment friendly”. Just because something uses less Co2 doesn’t mean it’s cleaner. A few ppm more Co2 in the Atmosphere is bad for the Climate, sure, but a few ppm more Mercury in natural habitats, rivers and lakes? Pff, who cares!
A recent study from the Association of German Engineers did factor in that most EVs are charged over night - even after 130k Miles (~ 200k km), a Golf TDI has roughly a 33 Ton Co2 rucksack, where an EV produced with renewables (ID.3) had 36 Tons.
“Most BEVs are charged over night, where only Hydro or Geothermal makes power”
Maybe in Iceland; anywhere with wind and nuclear power, this really is not the case.
And in most areas, how much share have nuclear and wind? Somewhere around 30-40% combined on average
About 30% in Europe/US; half that in China.
Electricity consumption drops sharply during the night - when wind power typically peaks. There are power companies that offer substantially cheaper rates at night for charging EVs for this very reason.
So something a swappable and universal battery design would solve that would allow lithium to be phased out by sodium batteries and would allow the usage of only the amount of batteries you’d actually need. So why are you against that as well? Or just BEVs in general?
Who said i’m against that? But with that argument, phasing out fossile fuels would solve a lot more issues than a few EVs.
Yes. That’s the entire point here. The answer is yes.
EVs have a lot of advantages over ICEs. It’s good that things are evolving finally to make EVs more than a niche. It however doesn’t remove the problem that they are still a car with all of those negatives, even if they pollute much less. In some ways providing an individual solution could harm efforts to reduce the number of cars on the road. It’s not a final solution, only a step to fix a few of the most obvious problems while retaining others.
Most US metro areas are just too spread out for mass transit to be a worthwhile solution for most people. The only solution to significantly reducing cars in the US is telecommuting; unfortunately businesses generally don’t like it, so we need to find a way for this to be encouraged by the government with subsidies or something.
Even if you live in an area where busses are, they’re slow and limited routes. Times are often inconvenient to work schedules. 1h 30m by bus, 50m biking, 3h 10m walk. A drive to work takes me 15 mins on average.
If you can drive to work in 15 minutes. Properly funded and prioritized transit can get you there in 10. Hourly bus service is not good transit.
Absofuckinglutely not
Those 15 minutes usually are on low traffic roads, getting you straight from the point you depart to the point you need to go. A bus route on its own would be at least 20 minutes if it has almost no stops. And that is without counting the travelling beyond the bus stops, because it is impossible to have a stop at every single building.
Those buses aren’t going to be driving faster than cars are allowed either.
Absofuckinglutely not
Looooool.
A tram could go faster and have signal prioirty at intersectuons. Buses are the lowest tier and lowest quality of transit.
Of course they’re cleaner. As long as your electricity isn’t coming from coal, you’re doing better by the environment than an ICE.
Even if your energy comes from coal they’re still more efficient.
Because the conservative machine, despite the love of Elon’s right-wing antics, never stop talking about how bad EVs are. Funny, the only time they act like they care about the environment is when they talk about how bad the EV batteries are to manufacture. While they roll coal and drive gas-guzzling mall cruiser bro-dozers all over the place.
Give him a few years into a potential Trump victory, and he will make Tesla to manufacture petrol cars.
Its about 40% more power efficient per mile but theres a couple of other trade-offs, still better yeah.
