I've seen a lot of posts here on Lemmy, specifically in the "fuck cars" communities as to how Electric Vehicles do pretty much nothing for the Climate, but I continue to see Climate activists everywhere try pushing so, so hard for Electric Vehicles.

Are they actually beneficial to the planet other than limiting exhaust, or is that it? or maybe exhaust is a way bigger problem?

People who say EVs do nothing just want to complain for the sake of complaining a lot of the time. EVs aren't ideal, but they are better and more crucially they shift the consumer thinking away from ICE cars and towards alternatives.

[–] SwingingTheLamp@midwest.social 9 points 9 months ago (1 children)

But it's also really dumb to go the other way and focus so much on EVs, isn't it? Why replace our cars with slightly-different cars, build a whole new charging infrastructure for them, and then phase them out, say, another 40-50 years down the line? It's not just tailpipe CO~2~ emissions at issue, it's poor land-use causing a major housing crisis, it's the cost of cars skyrocketing out of financial reach of many people, it's habitat destruction causing populations of wild animals to crash and many to go extinct, it's particulate matter from tires causing human maladies like dementia and cardiovascular disease, it's an epidemic of social isolation and loneliness, it's traffic violence killing over a million people a year, it's sedentary lifestyles leading to diabetes and cardiovascular problems, it's CO~2~ emissions from manufacturing cars and building the infrastructure that they need, it's the large-scale use of fresh water for manufacturing, it's the loss of autonomy for children, it's municipalities going broke trying to maintain car-centric infrastructure, it's the burden on people in poverty needing to buy and maintain a car, etc. etc.

I mean, the ultimate solution is to have cities and towns that don't force us to get in the car to drive everywhere, for every little thing, every day. There's little meaningful difference between transitioning cities away from ICE cars and transitioning cities away from electric cars. We could just start now, and maybe Millennials might be able to see some benefit before they retire. EVs are fine as a stop-gap measure while we work on that, but I see them being treated as the main event.

[–] peter@feddit.uk 4 points 9 months ago

I don't think we are focusing completely on EVs, they're just a very hot topic for some reason. There's plenty of high speed rail projects, pedestrianisation and other non car related innovations coming through

[–] danhakimi@kbin.social 54 points 9 months ago (1 children)

Buying an electric vehicle does not make the world a better place, but buying and using a gas vehicle makes the world worse by a bigger margin, so if you're buying a vehicle, an electric vehicle is probably better.

First priority is to get rid of cars in general. Try to use bicycles and public transportation. If you don't need a car to get to work, consider a car share service to replace your private car/private parking space.

EVs probably have around 1/10th the lifetime emissions of a gas car, which is still really significant.

[–] sping@lemmy.sdf.org 8 points 9 months ago (2 children)

Do you have a source for that because that's radically better than any number I've heard. Most analyses I've seen have been more like 40-60%.

[–] dom@lemmy.ca 10 points 9 months ago

Doesn't this hugely depend on the power generation in your area?

[–] jlh@lemmy.jlh.name 5 points 9 months ago* (last edited 9 months ago) (1 children)

No source, but I remember hearing that EVs earn back the cost of their manufacturing through their zero emissions within about a year. I extrapolated based on that with the assumption that a car will last about 10 years. I live in Sweden where our electricity is carbon free/ carbon neutral.

[–] Atemu@lemmy.ml 4 points 9 months ago

What you heard was probably about tail-pipe emissions which are very low compared to ICEs indeed but they only represent a small part of an EV's lifetime emissions.

In the EU, EVs reduce lifetime emissions by about 30%. Certainly not nothing but not anywhere close to solving our transport emissions problem.

[–] cooopsspace@infosec.pub 4 points 9 months ago

It's basically "refuse, reduce, reuse, recycle" except for cars it's "refuse, cycle, public transport,, car pool"

It is the nuclear power vs fossil fuels vs renewables debate all over again. Nuclear is much greener than fossil fuels but comes with its own challenges regarding cost, safety and waste disposal. Renewable energy like solar, wind and hydro are better than nuclear but the point is that nuclear and renewables are not enemies rather they are allies who have to band together to beat fossil fuels.

Public transport is like renewables, the best solution but one which needs time because years of underdevelopment and under-funding means that they are not as developed as they should be.

EVs are like nuclear. Not the perfect solution but have the capability to serve areas and use cases that public transport (renewables) can't. There are issues like them costing more than the alternatives and that the disposal of waste produced by both is a problem with an unsatisfactory solution.

ICE vehicles are like fossil fuel energy plants. The worst of the worst with regards to their effect on the planet. Their only advantage is that they offer convenience.

So I think we should stop the narrative that EVs(nuclear) are bad because the are not the best solution at hand but rather combine increasing adoption of both EV(nuclear) and public transport (renewables) to combat the true threat that is ICE(fossil fuel energy plants).

#1 - Burning fossil fuels (automobiles, specifically) kills 250,000 Americans a year. It causes a TREMENDOUS amount of pollution that is hugely impactful to health and quality of life

#2 - The only way to make our energy usage sustainable is to centralize production - ie you have to make all automobiles electric to start before the transition of the grid to renewables has a more dramatic effect. BTW, 40% of energy production of the US in 2023 was renewable. So our grid is getting cleaner and cleaner by the day.

#3 - Climate change. It is the most existential threat to our survival in our lifetime, bar none. We should do everything we can to leave the planet better than when we came. And right now we are failing miserably.

FYI, for all the naysayers saying EVs are "as" or "more" polluting than their ICE counterparts, this has long been debunked. Please do not listen to the Russian/Chinese propaganda or the comments of idiots that have no ability to analyze data.

[–] GreatAlbatross@feddit.uk 21 points 9 months ago (4 children)

I like to think of it as "better than".

They're not perfect, but they're better than what people might do instead.
I could swap my older car for a second hand EV, which would be an environmental improvement.
The current car does 50-ish MPG, about 1.5 miles per KWH. An electric would do 4+miles per KWH, which going in reverse is 100+MPG.

A bigger improvement might come from me getting the bus/train/bike everywhere, which is where the fuck cars argument comes from.
But I am disorganised, a bit lazy, and I don't want to shepherd 4 people onto the train, paying Β£150 to go 100 miles.

So for me, slightly better is better than no improvement at all.
The energy used can be green, depending on what the national grid is up to that day. But it's always more green than burning dinosaurs.
And the reduction in brake dust is always a nice plus.

[–] Silentiea@lemm.ee 11 points 9 months ago (1 children)

which going in reverse is 100+MPG.

Holy cow, why don't people drive in reverse all the time?

EVs are much better for the environment than ICE vehicles. Mass transportation is much better still.

[–] FluffyPotato@lemm.ee 20 points 9 months ago (1 children)

It's the same thing with recycling, companies trying to sell the idea that climate change is a personal failing of every single person even though said companies are responsible for like 90% of carbon emissions.

The problem with EVs is that we already have a better fix for this: public transit. Like trams and trains are both electric and would solve the microplastics caused by tires. Car companies are just pushing EVs to make a profit as always, the percentage of adoption required to effect climate changes isn't happening in the next several decades so just fix the issue centrally with proper public transit and actually effect climate change before we all die.

[–] scrubbles@poptalk.scrubbles.tech 12 points 9 months ago (1 children)

The often ignored part of this argument is that 50% of the US population at least lives in rural states. I grew up in a town with less than 10k people.

I'm 100% for more public transit, I live in a city and take the train to work. But for most Americans they do not and for the foreseeable future will not have public transit. I'm all for fighting for it, but it will be centuries before that happens.

EVs are NOT a perfect solution. They are a stopgap. But right now with where the planet is we need something now, we can't wait for centuries.

As for the companies are worse? Yes, they are. That doesn't mean we should just be complacent. It means we should be demanding they change AND lowering our own emissions. It's going to take everybody changing their lifestyles. The rich are the worst because few of them cause a huge percentage, but that doesn't mean the huge chunk of carbon we all put out together is excused either.

[–] FluffyPotato@lemm.ee 5 points 9 months ago (3 children)

I grew up in a small town of less than 6000 people and we had bus lines connecting it to larger cities and a bus line that went around the town as well, I never had to take a car anywhere and you usually didn't see more than 3 cars at once because everyone either walked or took the bus.

The problem with EVs is that won't be adopted at a rate to make a difference while building public transit could happen faster so as a stopcap they do nothing currently and probably won't until it's too late either while only working as a distraction while public transit could be just be built with the same political will behind it as EVs have.

Getting everyone to switch to EVs is not happening in several decades, for example here in Estonia people mostly buy old used cars because new cars are ungodly expensive EVs even more so, I have seen one EV in 10 years.

No product is good for the environment.

But an EV is a hell of a lot better than an ICE.

[–] DerisionConsulting@lemmy.ca 17 points 9 months ago (2 children)

The best solution is 0 cars anywhere.
A more realistic solution, is to replace planet-murdering cars with planet-kicking cars.

The math that I have seen on when an EV becomes better for the planet compared to an ICE is kinda all over the place, mostly due to how the power is generated.

Where I live, with a high amount of coal, buying a used ICE vehicle makes more sense than buying a new EV. If we drove more than just our weekly grocery trip, it might make more sense.

Doing "pretty much nothing for the climate" is hyperbole, I think. It's hard to say what the net climate benefit EVs might have, because our system is so complex. The numbers I found show that electricity and heating accounted for the highest, single category of CO~2~ emissions, at around 15 billion tons annually in 2020. Transportation came in second at around 7 billion tons. If we could wave a magic wand, and instantly do a 1:1 replacement of ICE cars with EVs, it would put a big dent in that category's emissions. It would also spike the electricity and heating category. Would the increase be less than the savings in the transportation category? LIkely, and the benefit would increase as more renewable electricity sources come online.

But even if we further used that magic wand to instantly get all of that new electricity for EVs from renewable sources, that still wouldn't touch the vast majority of emissions, in which car-centric lifestyles play a large role, e.g. manufacturing, construction, land use, even electricity and heating. So saying that EVs will do pretty much nothing for the climate is inaccurate, but so is saying that they're a big part of the solution. They're just incrementally better, and the size of the increment is arguable.

I think the push-back is mainly directed at that line of magical thinking that says that all we need to do is switch to EVs to drive to the grocery store, bring re-usable bags, and get Starbucks coffee in compostable cups, and the environment will be saved.

[–] essellburns 12 points 9 months ago (1 children)

In terms of Carbon, they produce about one third of the damage which an equivalent internal combustion engine car would.

There's a lot of factors that go into the final figures, like the specifics of the vehicle and the source of the energy used to charge it.

It's a bit like vaping instead of smoking. Neither are good for you but one is clearly worse than the other.

[–] FarraigePlaisteach@kbin.social 6 points 9 months ago (1 children)

Does that third also take into account any differences in manufacturing them? In other words, the entire lifecycle.

[–] essellburns 11 points 9 months ago

That's the best figure I've seen for the total lifetime impact.

It depends on a like for like comparison. A really massive and inefficient EV will not stack up so well against a small efficient ICE, for example.

There's just too much variation for any one figure to be both simple and accurate

[–] MNByChoice@midwest.social 10 points 9 months ago (3 children)

A lot of good answers here. One made me think about the good aspects, not just the game reduction aspects.

Electric cars are creating additional sources of funding for battery research, improvement of the electrical grid (there was a movement to get rid of central power generating and just use generators at each house), and electric generation smoothing.

Better batteries faster will help humans to make better use of the minerals we pull from the earth and the electrons we set in motion. (Imagine a battery peaking plant with 1980's batteries.)

Improvement of the electric grid could limit wildfires caused by them.

Smoothing electric grid drawls moves generation from peaking with natural gas to more base load, hopefully with something better than coal.

It is all about people who either are arguing in bad faith, or are focused on perfection.

[–] abbenm@lemmy.ml 9 points 9 months ago

other than limiting exhaust, or is that it?

Gee, when you say it like that, it makes extinction-level events sound not so bad! It is That Bad, so that would be the most direct answer.

The important thing to note is that even though some electricity is generated from fossil fuels, EVs eliminate the path-dependency that ties transportation to fossil fuels.

[–] Meatballs@mander.xyz 7 points 9 months ago* (last edited 9 months ago) (1 children)

We rape Africa for those metals the in a similar way we've been raping the middle east for oil. I guarantee once the US starts mandating EVs and the majority start to transition over there will suddenly be some reason we need to have a vested military presence in Africa, with the possibility of wars centered around countries with these metals that we need.

It's better for air quality and would do a shitload towards giving us some spare time to process climate change, but they come with their own baggage of bullshit in terms of environmental damage.

[–] Helix@feddit.de 7 points 9 months ago* (last edited 9 months ago)

I once calculated that my upper-middle class EV (2.1 tons in kerb weight, sadly) is better for the environment (indeed, carbon neutral since I'm only using clean energy) starting at 70,000km of driving usage. I'm at 20,000km now, so I'm already 28% there :)

[–] LadyLikesSpiders@lemmy.ml 7 points 9 months ago

"Pretty much nothing" is an exaggeration, but they aren't wrong in stating that it isn't the ideal solution. You've pobably already seen them talk about how shitty the Lithium mines are for the environment, and if you're still getting your electricity from, like, coal plants or other environmentally unsustainable places, well, you're not emitting CEO2, but the plant that outputs the electricity that fuels the car is now outputting more. It's still better than nothing, though

My personal issue with EVs isn't so much that they aren't perfectly ecofriendly, but that the biggest pushers of EVs are still capitalists with an industry to make money. The best we have in terms of solutions is better civil engineering for walkable cities and a robust and efficient public transport system. 5 EV buses is better than 50 EV cars. Thing is, companies making EV cars still want to make money. They have no incentive to actually push for public transport (Some like Tesla seem actively hostile towards the idea), as they would make more money on 50 electric cars than 5 electric buses. Considering how much power companies have in politics, especially in the US (which is from where I'm speaking), things don't look good

I'm certain that EVs are less of an issue in, like, the Netherlands, where public transport is better, and people can just bike everywhere. Again, though, I am speaking as an ignorant American, seeing how things are playing out here. Either way, EVs are generally preferable to ICE cars, but they are a far-cry from the actual solution they are being marketed as

[–] Thevenin 6 points 9 months ago

In the USA, out of every economic sector, transportation creates the most GHG emissions [EPA1], and the majority of that is from passenger vehicles [EPA2]. Significant portions of the industrial sector's emissions come from refining automotive fuel [EPA3]. US total GHG emissions are down around 20% from their peak in 2005, but almost all of that has come from the electrical power sector [CBO1][CBO2]. Vehicular pollution has dramatic direct health impact on top of GHG emissions [HSPH].

Transport emissions are the long pole in the tent for the US. Solutions to that will be the focal point of US climate strategy for the next decade. Barring the demolition of the majority of US housing to re-establish walkability, our two best solutions are EVs and public transit.

EVs cut lifecycle emissions by about 55-60%. [UCS][ANL][MIT][ICCT][BNEF][CB][MIT][IEA]

Public transit cuts lifecycle emissions by... about 55-60%. [IEA][AFDC][USDOT]

Neither is a magic bullet. Both get their asses kicked by bicyles (and to a lesser degree, microcars). Both get better with increased passengers per vehicle. Both can be fueled with renewable energy for additional reduction. Both can be manufactured with renewable energy for additional reduction. Both take surprisingly equivalent amounts of raw resources and energy. EVs need batteries that are carbon-intensive under current practices, but rail needs large quantities of steel which is equally carbon-intensive under current practices.

There are a ton of factors I can barely touch on here, so here's a rapid-fire overview. Public transit offers unique advantages from an urbanist perspective and the liveability of cities [ST], but that's objectively different from sustainability. The US has such low average ridership/occupancy that our busses have more emissions per passenger mile than our cars [AFDC1][AFDC2], and that was before the pandemic -- it's even worse now [NCBI]. Low ridership can be partly attributed to the incompatibility of American suburbs with public transit -- which could be a major roadblock because 2/3rds of Americans own detatched homes [FRED], representing $52t [PRN] in middle-class wealth that they will likely defend with voting power. Climate solutions will need to maneuver around this voting bloc. I personally think individual EVs and intercity rail are complementary technologies -- the more cheap (short-ranged) EVs are out there, the more people will lean on public transit for long trips. Heavy rail gets way better efficiency per vehicle mile than light rail or commuter rail and I have no clue why [APTA][ORNL], but I'm not as impressed by light rail as I expected to be. Since public transit and personal transport leverage different raw resources and face different challenges to adoption, we will achieve the most rapid decarbonization if we do both at the same time.

TL;DR

This is a huge, huge question, and anything short of a dissertation would fail to answer it objectively. My best answer is that the most effective solutions to climate change are diverse, engaging multiple technologies in parallel. EVs are a piece of the puzzle, but not a one-size-fits-all solution.

[–] hallettj 6 points 9 months ago

Here is a source with lots of detail on how carbon emissions compare: https://www.theguardian.com/business/2023/dec/23/do-electric-cars-really-produce-fewer-carbon-emissions-than-petrol-or-diesel-vehicles

The tl;dr is that EVs have lower lifetime emissions. If the relevant grids use low-carbon sources then emissions are far lower. (But not as low as bicycles.)

[–] sweet@lemmy.ml 4 points 9 months ago

I mean "nothing" is beneficial to the planet besides just stopping dumping CO2 into the air and toxic bs into the land and ocean. There is NO substitute for stopping corporate pollution, I mean nothing. That said, electric cars have more perks than just environmental impact, they do marginally help and they're cool. but in reality, you have to learn to tease apart what actual climate action looks like VS corporate adoption of "green washing" their products and putting the responsibility on the avg citizen. But that is infinitely hard for some people to come to realize.

[–] jabathekek@sopuli.xyz 3 points 9 months ago

Pretty much; although, (more importantly IMO) it also removes their economic support from oil companies. GHG's are still produced when obtaining lithium for the batteries, aluminium for the body, etc. There's as well the break and tyre particles that are still major pollutants regardless... despite all that it's still better then using a gas engine.

It's also not easy to convince someone to change their preferred mode of transport and EV's provide an acceptable (and in many ways superior) alternative. Not to mention taking the bus or riding a bike just isn't feasible for some people, similarly some places (like Japan with three separate voltage standards) don't have the necessary infrastructure and capacity to support EV's.

Exhaust and noise are still a problem. It won't do much on a climate level, but even if we manage to reduce car usage having the remaining cars be electric is useful. Both noise pollution and particulate pollution have negative effects on human health.

Maybe it's just my bubble but most climate activists I see are primarily pushing for renewable electricity generation, and consumption reduction across the board in all aspects of life. They are usually also against cars generally but it's a secondary subject.
