- There's no denying that electric vehicles are what most of us will be driving in the near-future. Countries around the world have pledged to phase out the sale of petrol and diesel vehicles over the next few decades, in an effort to achieve net zero carbon emissions by 2050.

Maybe we should stop having such a car-centric approach to "saving" the environment? One diesel bus can fit a 100 EV drivers, and one high speed train can fit as many as 1400 EV drivers! Imagine how much better that is for the environment!
like the video said, it’s not a silver bullet. EV cars are part of a solution but not all of it. it’s also a single from the bottom up that the public are shilling to switch, that helps with getting the energy cleaner at a country level
Ifrs end the
Yes i think you deserve the first high speed train line right down your street
What is this common sense you speak off.
I wouldn't be seen dead on a bus
In Adelaide South Australia there has been an all electric solar powered bus for at least 15 years!
Where ??? in the city only ....
E-cars - just another way to convince us to carry on consuming regardless. The only tangible advantage is cleaner air in cities, which is not how they're selling it to us, is it? Congratulations dear people, you have been well and truly greenwashed by the unstoppable corporate-growth machine which can obviously never advise simply consuming far less.
You don't get clean air from a burning ev!
Like anything in life, you dont have to buy one if you dont want to, no one is making you. But one day you will want to buy one, as they are superior product to burning stuff inefficiently to propel yourself along.
There is a lot of FUD about at the moment, that people will see through, when they experience an EV for themselves, everyone is fearful of change but after driving EV's for over 6 years, I will never go back to driving an ICE car, it's too expensive, dirty and a complete faff to use one. One pedal driving as in a EV is the way forward
Tesla started to move away from cobalt in batteries in the middle of 2020. Mainly because of cost rather than altruistic ambition, but hey, whatever helps.

I've known this for ten years and debated it. It's great that we can now put more evidence into the debate so that global problems can be adressed in a deductive manner.
What evidence? This video is simply a series of assertions. Let's have some real side-by-side comparisons.
@@GurungyNoHamuster So in other words, you don't believe how batteries are made and where the electricity to charge your car comes from??? Are batteries delivered by the battery stork???

We need to stop saying "if only we use public transport more".
Public transport is a huge inconvenience for long journeys and is often cancelled or delayed, at least here in the UK, and it's particularly worse if you want to travel to somewhere rural.
It's merely a pipe dream to believe we will realistically become a society that chooses public transport over our cars to go somewhere. Anyone who can afford a car is 8/9 times out of 10 going to use it to get themselves around vs public transport.
Can you imagine grandma riding a bicycle to go to the grocery store, in the rain or snow? It’s not feasible.
I grew up in the country, I took a school bus, it took over an hour to cover 5 miles. if you’re on the early part of the route, it takes two hours.
You're missing a few things about petrol/gas cars. The refinement of the oil into gas, the transportation of the gasoline, the storage of gasoline at petrol stations, the oil changes/ oil filters throughout the lifetime of the ICE car, the reduced efficiency of the gas car over time.
Whereas EVs get cleaner overtime ( as we switch from coal to cleaner forms of power production), ICE cars get dirtier over time.
I just wanna say fuels that going into powerplant also have to be refined you have that same issue there as well and include power grid loss and your outlets losses as well. Now I agree ICE cars also getting less efficient as time goes by, but compare to Li batteries it is nothing. You also should take in account that for recharging an EV you have to stop way more often and it gonna take you 40 min to recharge your EV if every one use EV recharging EVs are going to become a nightmare. Right now refueling a combustion car gonna take around 5 min or less and we sometimes see huge lines, think if that was EVs.
Stop lecturing us on personal responsibility when you jettison the chances of the only politicians to promote substantial initiatives on green, public transport alternatives.
The even cite a climate denier publishing his misinformation in a right wing Murdoch paper at 3:00
This video is misinformation.
CARB lies about the efficiency of EVs!!! In their ARB/MSD/7-6-94 they claim that battery efficiency is 80% and motor is 90%. These are LIES!!! Charging a battery in one hour is 5.88%. In 15 minutes it is only 0.3675%!!!! The motor efficiency depends on how many stops are made. Each tine it starts, the motor and system efficiency are almost ZERO!!!!
For ICEs, you seem forget that every liter of gas also need electricity to manufacture, from oil rig station, processing and transporting to a gas station. And yes if it’s powered by coal power plant, it will release much more CO2 compared to EVs plus an emission every kilometer you drive.
True- just as about 62% of electricity generated is lost by the time it reaches your house. Then another 10-15% of energy is lost to charge your car. As the video says - this doesn't count likely your electricity is from a coal or nat gas power plant.
The loss depends on the charge time. in one hour the efficiency is 5.88%, in 15 minutes it is only 0.3675%!!!
Batteries are shipped, shock! Like if machine parts are not
not by trans ocean route, no.
Pun intended?
I just read that the Volkswagen ID Buzz doesn’t use cobalt.
you really believe Volkswagen after the diesel scandal?
modern VW disel engines are most perfect and clean automotive engine. Diselgate was just the way to move VW out of US market due to US industry was unable to create perfect disel below 3 liters volume.
@@wingswings1665 Finally, some common sense. Whole VW "scandal" was heavily sponsored/organised witch hunt against eu/german car industry, which win global and most importantly china market (biggest car market today) at that time and this was big no-no for american bankrupted car industry. On the other hand, if we get back to "emissions", diesel cars (whole brands combined, no just vw) represents about 1% of whole ice car spectrum in usa (they conveniently moved their domestic made 4-5l diesel pick-up etc into truck category, where different emission standards etc are used). And if we go even further, they use heaviest anti (car) diesel standards, that is used in California only, due to heavy pollution in L.A., which, as we can see is definitely done by that 0,5% euro vw diesel cars, lol.
So, in the end, vw was "obligated" to pay biggest fine in history (over 40 billions, if i'm not mistaken), and move tens of thousands practically new vehicles into deserts etc, just so they have their "environmental" win. After that they realised, that wont do enough, since they're still no way compatible against other car industry, they went full mental with bev cars (aka musk), where eu was forced to have big monetisation for (only) their chargers onto highways, to let their factories being exclusive build into Germany without permits etc etc. All this because you know, environment..
A lot of the big manufacturers don't use cobalt anymore and haven't for many years now. Even when this was released it was a mostly outdated practice.
What happens to the batteries when they no longer hold enough charge? This is a critical aspect of the EV carbon and environmental impact which is seldom mentioned.
Petrol cars also got batteries that need to be properly discarded

EV batteries are either repurposed or recycled.
May be the time has finally come for sodium iron batteries initially for low performance and grid storage. As and when the technology develops, we can use the same for other applications which require greater energy density.
Let's use ecosia
No one talks about cruise-liners. If they are really serious about reducing emissions they would bad cruise-liners entirely. They have no use other than for entertainment and they are one of the biggest polluters in the world.

There have been various.
This is one of the best in recent years.
This is so obviously sponsored by an oil corporation
NO. The oil companies are one of the biggest investors in the EV market. They have invested billions in EV charging stations, manufacturing charging equipment, EV software, partnership with electric car manufacturers etc. The big winners in the EV market are the oil companies.

Petrol cars have all the problems mentioned in this video related to EVs AND the fossil fuel problems.

China use hydrogen fuel buses, which use electric to generate liquid hydrogen, which use the public power grid, which has the same "green" issue as using an EV...
That’s what I am doing - reducing my unnecessary car journeys and walking/cycling or getting public transport.
I just don’t see how the UK replaces 35m ICE vehicles with just EVs. Especially with the lack of infrastructure and Grid not being able to cope.
Either cut down - too many cars on roads or replace with Hybrids is the other solution. Think about when you use the car or share/borrow get taxis (they need to be green.)
3:53 Soviet Union have trolley electric bus
best use of electricy for transport, 100%. batteries are just another environmental problem.
I'd think they would focus on Hydrogen Cars. Green, affordable, works with the present infrastructure.
Possibly being able to make engine conversion kits for older vehicles in the future.
EVs create less brake pollution because they can use their engine to slow down. And it isn't the fault of the EV manufacturer that the grid isn't green. That is no argument against EVs. The economy has to dercarbonise, and electric cars are one piece of that puzzle. It's up to electricity providers to dercarbonise their product, not EV manufacturers.
I mean the grid is rapidly becoming green in 10 years the uk will get two thirds of its power from solely wind.
@@zUJ7EjVD All evs can regen brake and I haven't heard of any cons of that.
@@zUJ7EjVD Nonsense. It is an inherent feature of an electric motor.
Absolutely it’s rare occasions that I have to touch the brake in mine. The way the combined accelerator and regen brake works makes driving much smoother, so I can’t see the issues with additional weight. If you want to see that in action look at bus stops where the bus brakes you usually end up with a wave of tarmac and eventually a pit hole - as a cyclist I look out for these! With an ev you are never decelerating that hard because of the way the regen works.
@@zUJ7EjVD Go on, evidence that...provide a single EV without any regenerative braking?
Some have stronger braking features than others granted.
You can't discount vehicles without one pedal driving though.
I had an electric car when I was a young adolescent. It was called a power wheel. The battery was always going dead. lesson learned.
1) there's no carbon in oil refining
2) there's no geopolitical conflict over oil
Depends on color type.
“We have the technology but not the political will to use it” that part.
Also is anyone going to mention that fuel refineries are the largest consumers of cobalt by weight globally. Which use it to remove sulphur from petrol and diesel? No? Nobody?
Not so green when the car is a write off after a couple of scraps on the bottom of the car
Its not complicated EVs are greener than ice cars. They offset their carbon footprint in less than a year and won't produce any emissions ever. The life span of batteries can be over 15 years after that they can be used for 15-20 years as static storage before being recycled to get the rare elements back. Meanwhile petrol uses 90% of mined cobalt in it's desulphurisation process.
@@zUJ7EjVD I don't understand what you're saying? Its not hard to charge an ev. Also whats the point of buying a car if you drive afew times a year? There also more ev makers than tesla. You don't really need to repair evs that last a long time than you only need to replace the battery after like 20 years. Theres many third party places that do this in europe atleast.
It takes 2 years (realistically 2-3 years) to offset the carbon footprint. So those people that replace their cars every two years are causing more damage than any ICE driver.
They do produce emissions - not at the car, but every time it's plugged in it's producing emissions. The UK will never be 100% renewable on energy (not possible with our weather, river sources etc).
They're not the answer. In a few decades they'll be obsolete and will be replaced by the next fad.
Source?
@@nezudough2423 This is basic info at this point in fact my figures are very conservative compared to what we know now. What do you want a source on specifically? fully charged does great stuff on this.
Wasting most of the electricity by fast charging negates that. Charging in one hour is 5.55% efficient, in 15 minutes it is only 0.3675%!!!!

@@michaelrch cherry picked data . wow, if that isn't what the entire left has been doing for eons lol. There's plenty more data that proves Electric isn't actually as green as they want us to believe it is. If you want a car just to putz around in & go grocery shopping, great, enjoy the battery
Yes, that was my reaction too -- though I had noticed a weird anti-EV line from the Gurdiran from a couple of years ago. It's bizarre -- I actually wondered whether it was taking bribes from the fossil fuel corps.
The extra tyre pollution has been debunked too…
1 ton of lithium mined = 5 to 15 tons of carbon

And seriously, are you going to complain about the problems of pay and conditions for mining of materials for batteries while totally ignoring the fact that this goes on at a scale orders of magnitude larger for the materials for producing ICE engines and the BILLIONS of tons of dirty fuel they use every year?!
Yes, conditions for miners are often terrible, but that is common to all mining. The cause is capitalism, not batteries FFS.
🔥🔥
Can you point to me the whereabouts of the oppressed child miner in the US? Any other western nation? In fact countries like Australia miners get paid very well.
@@Right-Is-Right
That's not what I was getting at.
There is a common trope used by fossil fuel shills that EVs require lots of mining and that the mining communities around the world, especially in Africa and Asia, have a horrible time and get paid next to nothing. This is actually true. But it's MORE true for fossil fuel extraction and the attendant mining than it is for mining for materials for batteries. So raising this issue is either catastrophically ignorant or it's a deliberately misleading attack on EVs.
The most egregious example is criticism of mining for cobalt in the DRC. You hear this ALL THE TIME from people attacking EVs.
What they fail to mention is that child labour in the DRC was tiny and has all but stopped now. But even while it was going on, the biggest buyer of that cobalt was,..... the fossil fuel industry!!!
@@michaelrch correct... and the video ignored the fact that Tesla began moving away from cobalt in batteries in 2020.
When I saw "air fuel synthesis" 11 years ago I thought to myself "yay, that's climate change and sustainable energy sorted forever", because generating renewable energy is largely a solved problem, but storing it in vast quantities for hard-to-electrify applications wasn't. Just converting the renewable energy into the form we conveniently use it in was obviously *the answer*. And then it disappeared!
Electric and human-powered transport are the obvious solutions for transport's urban air pollution issue, but beyond that a mix is needed that also supplants fossil-origin carbon for things like plastics manufacturing. Only hydrocarbon synthesis gives that, and it's being rejected by silly 'decarbonisation' which is throwing out the baby with the bathwater. There's nothing inherently wrong with the carbon chemistry the world works on, only with the source of the carbon we've been using.
No vehicle or other product is 'net zero' until it's made from raw materials which are themselves net zero. The only way we can do that is to 'cut and shut' our economy at the refinery output stage, so that all those hydrocarbons come instead from air-captured carbon and renewable energy. If we do that, all downstream industry and applications are net zero too. Tailpipes, gas CH, and plastic sporks too, all net zero.
Truth is i don't care. All i care about is that EVs arent taxed as much as gas cars, so they cost about the same to buy, road tax on EVs is 3 times cheaper, and electricity is on average 4 times cheaper compared to gas with reasonable fuel economy. Considering i dont drive very far, it's a great alternative purely on budget consideration.
A provocative and informative doc on the CO2 Pollution caused by Electric Vehicles (EV’s) during their construction, (especially of their Batteries and the rare metal used), and during their driving life; ofc the Pollution caused by driving an EV depends largely on how the Elec used to charge EV’s is generated !
Co2 is not a pollutant.
The battery production is not a one time thing. You'd need more batteries per car
This talks as though petrol is magic and magically turns up without effort at petrol stations. Petrol additionally using the likes of Cobolt. The power grid, sure, countries are cleaning up the power grid
It’s clear that the starting point is reducing car use.
This makes me want to ditch my Guardian subscription, after decades.
- Really, G. you are "just asking questions" too? Like Faux News?
- Hand-wringing over lithium and cobalt mining while ignoring all the cobalt used in petrol refining? Compared with the humanitarian and environmental impacts of petrol? Perleeze!
- Material resources have to be transported? You don't say! Ditto _everything_ else!
- And let's not forget to mention that old canard "particulates from tyre and brake wear" (but let's not mention that EV's rarely use friction brakes, eh?).

Yes, we should all drive less. Yes, we should all drive smaller, more efficient cars. But many people will need to drive, so they should drive electric, asap. Once EVs are in the majority and it become socially unacceptable to drive a combustion vehicle, then we'll quickly get to 100% electric and a cleaner transportation future. But by posting this, you are delaying the transition. And that's barely forgivable.
No, they should not drive electric, and people shouldn’t have smaller cars!

@@riddhimaansenapati5006 Is it, though? It seems to me to be a thinly-disguised attack based on half-truths and received wisdom (also: giving many people what they want to hear).

@@brushlessmotoring what fact free exactly? facts are facts.

And the huge depreciation of an EV.
And this is why we use the combustion engine to manufacture your electricity in ad plants. It’s not green. The only answer is to travel less.

Problem with “green” energy is that it’s not environmentally clean. The heavier lithium battery cars wear tires out faster creating more airborne particle pollution. The heavy metals despoil the environment in their mining and eventual disposal with highly toxic minerals. They also require energy to be charged - most often fossil fuel energy. Hydrogen might be a far better solution.
On the other hand microplastics, pesticides and pharmaceuticals pose a genuine threat to human survival.
Yeah its really lucky that ICE vehicles don't need any mining or refining of materials at any stage in their life 🤣 Who's using fossil fuels to charge their EV in 2024?? Also if you don't have green electricity where are you planning to get environmentally friendly H2 from? 🤔
Please include the environmental damage caused by a burning ev
Offset by the 100 times more likely fire in ICE vehicles.
I think buying used cars and taking public transport when practical is the best option until governments provide clean electricity.
It's much more sustainable to buy a one year old hybrid and use it for 10 years than ordering and building a new electric car every three years because there's a better model.
Hybrids are the answer!! They don't waste electricity by fast charging, don't have a range problem and greatly reduce fuel consumption.
If the answer was as simple as putting 1000 laptop batteries in a vehicles floor pan companies like Toyota would have been all in on BEVs years ago. There reality is its just not a better solution, including overall CO2, especially compared to Hybrids.
Do you have a source for this? Would be really interesting to see your research in this area

Even for power grids relying on fossil fuels, countries could adapt EV vehicles for long hauls as break-even pt (carbon footprint) can be done in say two years of 45,000 kms per year (125kms per day).
Over 60% of the electricity feed into the grid is lost in conversion and transport. There is nothing green here, the pollution is just centralized to the power station.

There is nothing green about an electric car. They're great though. So comfortable and modern. But no one should be dumb enough to pretend they're saving the planet by driving a Tesla.
In the United States, utilities have retired hundreds of coal plants over the last decade and shifted to a mix of lower-emissions natural gas, wind and solar power. As a result, researchers have found, electric vehicles have generally gotten cleaner, too. And they are likely to get cleaner still.Nov 9, 2021

I mean they still are better than ICEVs, though they certainly are no saints
100% agree!
Considering you would need to drive one for around 30,000 miles before it becomes “greener” than a typical ice car it’s a lot better. And that’s without taking into account the number of lives you could save through clean air.
@@viralclipsnvids Then you would need to buy another EV much sooner than ICE and you would increase the demand for electricity (electricity sources pollute depending where you live) and in the US (I'm not sure about other countries) some states are having issues with the electric grid being overloaded.
Are EV's green? Yes.
Is our Grid green, and ready for EV's ? NO.
Nothing is green.
real green technologies are banned by, whom?
Typical gas vehicle is only 25%, 75% is wasted. Natural Gas combined cycle power plants are 50-60% efficient. So if you use a MWh a year in a car, you get 250 kwh of locomotion. You use a MWh combined cycle generator you get 550kwh, double the efficiency of the gas vehicle. There are small transmission losses to the EV charging station and the charging and discharging has small losses also so perhaps 80% more efficient. The Guardian should hire an electrical engineer to proof this story.
ethanol is the solution
Yeah 20-80% for fossil fuel car efficiency ! Say a true
What about using those lifetime battery's that use a radioactive isotope?
To change 'the collective mind' is much more difficult than to change technologies. It simply cannot be done. Evolution marches on.
Theres no way out, electric cars are dominate the car industry and parallel the green energy are increase the production, in few years the majority of energy suply will be green!
95 percent of the world's energy comes from fossil fuels.
Great! So China has the most electric buses but their electricity is mostly from coal. That makes sense
It's still cleaner because the coal plants run at maximum efficiency to produce electricity vs your average minimally-maintained, inefficient petrol engine inside every car.
@@elmohead coal is literally never the answer. It's the worst of all options for fuel. Not a great deal of power, and absolutely disgusting for health and environment, from the mining through to the refinement and burning pollution. China's air quality is horrendous, especially for such a rich and developed country. Even scaling up nuclear for now is better, and increasing speed of transition toward renewables. Wind and solar still offer China vast untapped potential and low hanging fruit.
Considering the latest studies show that tire dust releases thousands times more air polluting than tailpipes, those heavy EV eating tires should really not be allowed on the road.
Hmm, we never seemed to mind SUVs like range rovers being heavier and emitting more tire particulates, before EVs came along, it's almost at though this is "Selective Outrage" designed to focus people's anger away from gasoline cars, like ignoring the cobalt used in Oil refining, and ignoring that some batteries don't use cobalt (Tesla SR+) but that some cobalt mining is bad, so your phone's battery is bad ... but, lets only call out EVs, and not mention some EVs don't use cobalt at all.
Hmmmm. I wonder what's going on here then? Maybe this is The Guardian practising misinformation about EV's to keep their Oil and Gas advertisers happy?

The claim that Electric Vehicles are environmentally friendly is a huge lie or a major misconception because the environmental impact equation is computed only after the battery is charged when one adds required battery charging process to the environmental impact equation one finds electric vehicles pollute much more than gas or diesel powered vehicles.
Most power on the USA electric grid is fossil fuels (coal, diesel or gas) about 70%, nuclear provides about 20% and so called "Green" energy (wind, solar and hydro) about 10%
Fossil fuel plants and nuclear plants are about 30% to 35% efficient.
Line losses from the power plant to the end user are somewhere between 7 to 10%.
Battery charger efficiency is between 80% to 70%
Battery efficiency is about 70% for a new battery and about 50% for an old one. Note battery efficiency is significantly affected by temperature (as battery cools it becomes less efficient. )
Efficiency of EV is about 70% but add required lights, all it's electric gadgets, compartment heating, Window defrosting and air conditioning it's efficiency drops to about 60%
The complete environmental impact equation:
Best case. Worst case
Fossil fuel & nuclear plants 35% 30%
Line losses -7% -10%
Equals. 28% 20%
Battery charger. X80% X70%
Equals. 22.4% 14%
Battery efficiency. X70% X50%
Equals. 15.7% 7%
EV efficiency. X70% X60%
Grand total. 9.8% 4 .2%
What all this means is when charging from the electric grid to get just 1 useful watt at the EV, best case over 9 watts are used at the power plant and worst case 23 watts are used. This is far from being environmentally friendly.
So driving an ev car is more of a lifestyle change than reducing carbon emissions. Got it
You offer no proof of your statements. Some reports and some studies by unknow authors is not useful or correct information.
If you really wanna drive a green vehicle, go to a scrapyard and find a 1989-1994 manual transmission Geo Metro that will get you 45-52 mpg combined, have it restored and drive it til the frame breaks apart and no longer can be driven. Ive owned one for two years. best car ive ever owned
Not sure I'd want to be driving at 60 when the frame breaks mind you...
@@leskennedy well then dont drive it once the integrity of the chassis appears to be compromised, or near to it
Solution to the problem, why don't you just walk bruh
But with today's lithium-ion batteries, EVs can go so far.
Discussing the impacts of battery production in relation to cars without even mentioning the massive environmental impact of fossil fuel production is ridiculous.
This really isn’t that complicated. EVs are significantly better than ICE cars, and less or no cars are way better than both.
They even cite misinformation from a known fossil fuel shill and climate change denier, in a Murdoch paper, at 3:00
This video is straight up misinformation.
Public and collective transport is the only way into becoming an advanced and sustainable civilization
You missed the part where EV's running on electricity produed from natural ga sstill output 76% of carbon diozxide as a comparable car nd that was just one study, to make that "yes EV;s do create less CO2 than petrol and diesel cars over their lifecycle' is a huge a stretch that has to ignore the CO2 of coal powered power stations.
@@Right-Is-Right
Where are you getting those figures?? Planet of the Humans or perhaps Exxon Mobil themselves?
Have you just tried googling
EV lifetime carbon emissions
? The studies all cite reductions over around 50% or more.
Check the CarbonBrief article on this. They are very reliable.
"Factcheck: how electric vehicles help to tackle climate change" from 2019.
And the situation is getting better every day as renewables displace fossil fuels, especially coal, on grids around the world.
@@michaelrch where did I get the figure from? why did you not watch the video or read what I typed? and no, i am not going to Carbon Brief, they are, well self professed left wing. Seriously their 'Director and editor' is a ex guardian employee, who has never even studied science, even though he was given an honorary geology degree for his climate change shilling.
EV is not perfect, but is certainly better than petrol. It is a start using EV, until it get better through investment because of mass acceptance. Think about how far petrol car has advance since mass acceptance. Look at mobile phone advancement. EV will improve on efficiency and technological improvement to be more green.
The real CO2 output comes from aviation and shipping.
Personal cars are a small part of a much bigger problem.
We could all ride horses - but they produce CO2 also :-)
tbf to the horses, they're also carbon neutral because they sourced their carbon from plants which sourced it from the atmosphere, so that carbon was already in the environment.
Not complicated. Ev's are not even close to green.
In the 20th century, government limited vehicle gas mileage to sell more gas and generate more gas taxes. Now they are limiting high gas mileage cars (we can get 500mpg, imagine 20x less CO2) so EVs appear more economical. While battery power creates 25% less CO2 today, they are devastating to the planet surface and fresh water supply.
What the video fails to mention, is that the precious metals used in EV batteries are subsidized, and will NOT get cheaper as demand increases. Precious metals only increase with increased demand. You can expect to pay over $150,000 for a Honda Civic EV.
The end goal of government is to eliminate personal transportation. (Grandma can ride a bike, in the rain.) And this video promotes eliminating personal transportation. If you have less movement, you have less freedom.
Correct me if I’m wrong but do electric cars move around on rubber tyres
In short EV’s are not as green as you would think over its lifespan
bicycle
We could make the EVs much, much smaller, about the size of a 4 seat smart car for 90% of journeys, at no more than a tonne weight- eg Dacia Spring, small battery, light and charge at home. Noone needs s 2.5 tonne EV to go to the shops or school. They should be banned. Secondly, a lot less moving parts, but about a thousand times more electronic chips and relays that all need software updates all the time. It is absolutely clear (see Nissan) that software updates will be stopped after a few years, like with smartphones, where the life is about 5 years for updates, so the EV will have to be thrown away (recycled- which is energy intensive). My ICE car is 21 years old, never goes wrong and does 45mpg, it is far more carbon efficient than any current EV. No credit is given for this reality.
I think there is a false equivalency there that EVs are the big and heavy option and ICE is small and light. More people drive 2.5 tonne ICE vehicles than 2.5 tonne EVs and there are many EVS that are available right the way down to small
