I think the biggest point which was covered and I come across time and again is that when anti-ev people compare emissions they almost always look at mining of lithium, cobalt etc but then only include tailpipe emissions from ICE and totally ignore the oil extraction, processing and transport.

Well for a start you've just plucked the 'two times as quickly' figure out of thin air. EV’s aren’t twice the weight of another comparable model so how do they cause twice the road wear? The the BMW 3 Series vs the Tesla Model 3 - 1800kg vs 2100kg which is about 16% more. Yet you claim 100% more road wear? Secondly, many of the heaviest cars on the roads currently are large ICE SUV's such as Range Rovers, Large Audi’s, Large Mercs etc. Modern cars have been getting heavier and larger consistently for at least the last 20 years and I didn’t hear anyone complaining about road wear whilst that was happening but now that EVs are on the scene and are a bit heavier suddenly its an issue. Loads of cobalt is used to remove sulphur from oil in the production of petrol/diesel and is also used in batteries in consumer electrics like mobile phones. No one has cared about that for the last 20 years but suddenly when EV’s came along, cobalt use was a big problem. Oil refineries use massive amounts of electricity. No on cares how thats produced but if an EV has any fossil fuel produced electricity in it suddenly its an issue. Bottom line is that whatever metrics you choose to use, EV’s are over all cleaner and more environmentally friendly. They are more efficient and do more with less resources and almost all of them can be recycled which isn’t true about oil being burned in an engine. They are certainly not perfect but cherry picking the odd little statistic here or there doesn’t change the fact that oil extraction, transportation, refinery, more transportation and then burning in ICE that are at best 35% efficiency and pump out poisonous fumes in the towns and cities we all live in is worse for the environment and worst for us than using EVs.

Thanks for your contribution to the environment.Infrastructure in Australia hasn't caught up to the point that owning an EV is completely practical yet, particularly for people that live in areas where long distance travel is normal. It seems like Evs really make sense in high population areas like cities where short trips and good infrastructure are the norm. Lots of people live in cities in Australia too, don't get me wrong but if for example, one day I decided to travel 900km from Melbourne to Sydney, I'd have to think very carefully before driving a currently luxury price tagged EV. If I did own an EV, to achieve the same outcome, I'd probably need to either a) fly then hire a car which is terrible for the environment or b) keep a petrol car as well as an EV, equally terrible.

I love my car but recently on a visit to Basel Switzerland I was seriously impressed by the tram network. Many people use bikes and walk, and Basel is also part of the huge European rail network.

Fantastic presentation of the subject matter. I'm a brit living in Norway where the use of electric cars is extremely widespread, the charging network is pretty good and almost all the electricity is generated using hydro power (so all in all, a pretty unique situation looking at the global picture). I've owned a VW e-golf for the last 4 years, but I also have a diesel VW Touran for practicality purposes (big loads and it has 7 seats). As the Touran is getting old and the options are getting better, I'm on the verge of buying a larger electric vehicle to replace it. Last week I rented a VW ID4 to do a long journey within Norway (as my son is starting a year at University on the other side of the country) to take the opportunity to see how it would go using an electric car for long journeys. This was the first time I've ever done a journey more than 100 km in an electric car and the first time I've ever used a public charging station. The journey was roughly 360 km (220 miles) and was a reasonable overall increase in altitude (roughly 450m), but with a rough range of 500 km, I was fairly confident the ID4 would be able to do it on a single full charge. We stopped to charge anyway while having a bite to eat (speed limits and intercity roads in Norway are not what you would call ideal, so it's roughly a 6 - 7 hour journey). The 20-25 minutes it took us to eat was enough to put an extra 200 km range in the battery, so 'range anxiety' was never an issue. On the way back, I didn't even consider charging as the battery level hardly moved in the middle of the journey because of the regen keeping the battery topped up as I came down off of the highest point on the mountain roads (I would guess I got about 100 - 150 km 'free'). The whole experience was quite honestly, fantastic, with two exceptions -1 being something with the car and the other the charging network. The thing with the car is the touch sensitive controls for just about everything in the ID4 (irritating and temperamental - as documented on numerous reviews of the ID4). The thing with the charging network is the absolute insistence of the charging companies to require a mobile phone app to use the chargers!?!?!?! There are a few apps which cover multiple charging companies, but our experience was that there are various incompatibilities with certain phones (payment methods, android versions, Ios versions) which don't present themselves until you actually try to charge the car (they install ok initially, but can be fiddly with setting up payment methods - but may not ultimately work anyway). I had numerous problems with this on my Sony android phone (which is admittedly not the newest model, but it's also not ancient either) - with both the multi-company apps and the dedicated single company apps. Why oh why can there not be standard card reader payment on these chargers - just like a petrol/diesel pump?!?!?!? This is something that the government needs to step in on and state there has to be a standard card payment option on all public chargers, in my opinion. Fortunately, when I did get one of the apps to work on my phone, there were more than enough chargers available around the major routes and towns to travel around without any concerns. So, with more and more public charging stations popping up on a regular basis, there's no reason not to take the plunge (at least here in Norway) to going fully electric now that there are a number of vehicles with over a 400 km range.

In France there is Renault/Solvay who have a pilot plant and Northvolt/Audi in Germany have already produced new batteries from old at theirs. EV represent an opportunity to develop a circular economy, something that could never be achieved with the ICE.

It's not only about how you travel but also how far you must travel. North American suburbia types of housing force people to travel long distances just to do their basic shopping.

What a revelation it is. And I'm not able to charge at home either, but asked my company to install type 2 chargers under the government incentive. So a month before I received my car there were a pair of Zappi evses. And, as this is the UK, charging at work is free.

Personally, regarding cars, I still subscribe to keeping older cars, maintaining them well, and maximising the life of that older vehicle. I don’t own a car anymore, but if I were looking for a car and could find one I’d buy a Holden of the F, E, or H series which date from 1958 to 1984.

Only charge above 80% if you're actually going on a trip that requires the extra range to reach the first charging station. Do some research to check the Optima battery charge for your particular vehicle brand. Some Tesla's battery packs have lost almost nothing after 200,000 miles. And I think there are even a few that have lost almost no range after 300,000 miles.

Great video! For the second report, comparing types of transportation side by side, are the transportation mediums (rails, roads, etc) factored in? I was surprised to see EVs so close to trains, etc. EVs (being much heavier than traditional cars) will mean more road maintenance. We already know that suburbs are actually a money sink for cities because of the high cost of road up-keep for the relatively low number of drivers in the area so it would surprise me that their carbon cost would be almost as low as a train.

This might be because of the speed difference. You might imply that frontal area is the only factor that causes drag, but length and skin drag are super relevant too. This report might be based on the average rail line distance travelled, of which many are carried out by 160, 200, to 300 or some even 350 kmh trains. Drag increases by the square of the speed. It makes sense that the numbers are not much lower. If we were comparing to a 120kmh train, i bet it would be a quarter or less. Also it seems like the train not always being full was taken into consideration. Same with the bus, or it would be waaaay lower.

Battery and capacitor science and technology already has much better options in labs and prototypes. The same goes for fuel cells and those can be used in electricity hubs in more rural areas for EV vehicles too. There are already some pretty good fuel cells for things like ethanol and butane so we don't even need to work with far more difficult hydrogen or methane.

The question we should ask is why we need transportation in the first place. Because we do not live, work, produce, grow food and recreate locally enough. Solving this will save energy and also be an improvement of independance and stability.

So I sold it and started cycling 3.5 miles to work each way daily, with the intention of buying another car when things got back to normal. A year - eighteen months later I can't think of a good reason to get a car again! I cycle everywhere, use public transport for longer journeys (trains to middle of France for - you guessed it - a cycle touring holiday!) The main exception to this is monthly or fortnightly 'big' grocery shops where I use a taxi home, and sometimes to the supermarket, too. Panniers are plenty good enough for weekly shops. Occasional days out with friends and family mean they have to pick me up in their cars or we meet in the middle near a train station.

Lowering one's personal transportation related CO2 emissions to nearly zero is definitely a step in the right direction, but I would argue that this alone is not sufficient to "qualify for a halo". To fully reach a zero CO2 emissions lifestyle, one must not only null out their personal transportation related CO2 emissions, but also their household electricity and home heating emissions, as well as all other CO2 emissions that are occurring elsewhere in society (ex: at factories/mines/farms/commercial businesses) that are necessary in order to support your lifestyle. The average total per capita daily energy consumption by residents in the US in 2019 was roughly 250 kWh. Some of this energy comes in the form of non-CO2 emitting sources (ex: solar, wind, hydro, and nuclear), but roughly 200 kWh is due to the combustion of coal, oil, and natural gas. To "qualify for a halo" and actually live a true net zero emissions lifestyle at a moderately high standard of living (ex: "average" for the US in 2019), you therefore would need to somehow offset all ~200 kWh of combustion energy occurring in the economy, associated with your lifestyle. This is actually quite possible and it isn't even all that difficult, based on current prices of solar panels. It also does not require a reduction in quality of life or major changes to one's lifestyle. A person can produce approximately 200 kWh of electric energy per day, by purchasing around 50 kW worth of solar panels, and installing them in a grid tied configuration, in a reasonably sunny location. However, it should be noted that grid electricity, when produced by burning coal or natural gas, has a relatively low thermodynamic efficiency, which means that 200 kWh (thermal) worth of coal or natural gas many only produces around 80 kWh of electricity. Therefore, if you simply buy enough solar panels to become a net exporter of roughly 80 kWh of electricity onto the grid per day, this will cause a reduction in coal and/or natural gas consumption elsewhere in the grid, by around 200 kWh (thermal) equivalent, which will null out your effective personal CO2 emissions. Therefore, you do not actually need to buy 50 kW worth of solar panels, as somewhat less (maybe 35 kW in a reasonably sunny location) is potentially adequate, if installed in a grid tied setup. At today's prices, 35 kW worth of solar panels (by themselves, without installation, racking hardware, or inverters) can be purchased for around $21,000 USD (mid 2022 prices). When the solar panels, plus the inverters, racking hardware, and ancillary hardware are included, but excluding the non-CO2 emitting "soft costs" associated with installation (labor + profit + government overhead/permitting/inspections + insurance overhead, etc.), a grid tied system of 35 kW rating can be built for roughly $35,000. If a person does not want to personally install 35 kW worth of grid tied solar equipment, they one could instead simply buy the equipment, and then just give it away for free to anyone that wants it. If you give away free solar panels and inverters, then in all likelihood, the person accepting the "free" equipment will eventually install that equipment into a system which will in fact reduce grid electricity consumption, which will reduce required coal and natural gas consumption somewhere in the economy, by a value approximately equal to 200 kW (thermal), which will effectively null out all of your personal CO2 emissions associated with your existence. You do not need to ride a bicycle to do this. You can do this, even if you still wish to drive an electric vehicle, or even a relatively fuel efficient gasoline vehicle. If you still drive a gasoline vehicle, you will emit CO2 locally, but your gifted 35 kW worth of solar panels will still offset the production of CO2 elsewhere in an amount quite a bit larger than what your vehicle will normally emit (unless you drive a large amount of annual miles, and/or use a gas guzzling vehicle, in which case more gifted solar panels than 35 kW would be required). Minimalist living is not required. Demanding that governments and corporations do something to make changes to reduce CO2 emissions is not required. Individuals can in fact make a difference, by effectively nulling out their own CO2 emissions, simply by purchasing ~35 kW worth of solar panels (+ inverters + racking hardware) and then doing something to cause them to eventually get deployed. The amount of solar panels required however does depend somewhat upon where they will ultimately be installed. Residents of high latitude and/or cloudy regions (ex: Canada and Europe) would need to buy somewhat larger quantity of solar panels (probably closer to 70 kW), due to the lower performance of the solar panels when installed in relatively poor sun access locations, such as the UK or Germany.

'determined not to be convinced' is such a good quote. I suspect lots of these people are rejecting reality to satisfy some emotion like guilt, fear or shame. No one should feel guilty for driving a gasoline car, they should instead be angry at the oil companies who for decades pushed propaganda while millions die every year from air pollution. That anger, which would be correctly placed, is a much stronger motivator to buy an EV I think.

I have lots of cheap plastic for sale. I just need to buy 2 ships and a net.

I'd like an EV - once I can afford a second-hand one. That's going to be a long while unfortunately. In the meantime, I rarely use the car I have, it's small, efficient, economical and very well-maintained. Last year, we did 1,000 miles by car and it's set to do about the same this year. We're on the point of going back to using more public transport again whenever it's possible. (I used public transport right until the age of 52, when I finally had to learn to drive because of cut-backs in local bus services. Now it'll be case of frequency and just how much it costs to travel). Personally, I don't fret over the fact that I do have a 'gas-guzzler,' because I have made, and continue to make, a lot of pro-environment changes to my life: Been a vegetarian/vegan for over 40 years, my family committing to the same diet for the past 4 years. I've been a regular tree-planter for about the same amount of time. My career was as a gardener, but with elements of conservation work involved. I have only flown by plane once in my life (UK to Iceland), and that was not by choice. Although I loved being in Iceland, I vowed never to fly again, and I never have. (My family are also committed non-flyers). We are a make do and mend-type family, enjoy raiding fly-tip sites and lugging back stuff to make into other things. My son has got a new bookcase my husband has just finished making out of dumped wood. We buy most of our clothes and shoes from charity shops, sometimes furnishings as well. After the stream by my house emitted a methane 'belch,' which not only stank to high heaven, the fact this happened at all really worried me. So, over the past couple of weeks, I have begun to remove buckets of wood and leaves out of the stream and compost them aerobically to reduce the production of methane and nitrous oxide. There will be very little difference in the amount of CO2 emitted as these materials break down, but the other 2 were my primary concerns. I'm in the middle of planting a 2 acre permaculture/rewilding garden, and not only is this bringing back lots of wildlife to the area, it's encouraging species I've never seen here before. I have been picking my own home-grown fruit and vegetables every day for weeks now. Really saving money, with a fine crop of potatoes, blue and blackberries to come. I'm not just concentrating on those fruit/veg plants that are often seen in UK gardens, but planning ahead and starting to introduce those that can cope better with the new, hotter British summers. Today I began making a little activated biochar from dried out brash (thin wood collected from the stream) for the very first time. I was unsure how effective biochar would be, so I'd been doing a lot of research into it, making sure I wasn't getting into something that would have so little impact it wasn't worthwhile. It's a bit of a messy job, and rather hot work on a day like this (31C in Scotland! I think I might try and do this job the same time as cook a bit of food in future. Kill 2 birds with one stone), but it's supposed to be pretty effective at locking carbon in soil. Tomorrow, sowing more food plants.

The thing I like about electric cars is that you can choose where your energy comes from, from Solar to charging it of a dirty diesel gen set. In many places, you can sign up for your household electricity (the most common way to charge an EV) for your quota of power to come from various green sources.

I totally get driving an old car because it still works, and it is far cheaper than buying a new one... The first R of the three comes to mind, but for pollution, that argument does not hold. An EV needs to overcome the energy embedded in it's manufacturing when compared to an ICE vehicle in order to reach a "break-even point", after which it is truly very close to zero emissions. The typical "pay-back" period for this is about two years (averaging a lot of things... ) Translation: every two years of usage of a ICE car is the same as the impact on the client of getting a new EV. so if you use an old gas car for more than two years, it's worse for the climate than buying a new EV. Driving a car for 10 years, an ICE vehicle will be pollute about the same as 5 EV's. Also this two year payback is based on the power mix in place where the batteries and cars are manufactured. As the grid cleans up, the embedded carbon from manufacturing goes down, speeding up the payback further.

Well done! (as you always do!)

Quite a good report, but a few things have been missed: Firstly is the extra weight of EVs. They are probably on average at least 20% (probably more) heavier than equivalent ICEs. This will give the same percentage increase in wear on the roads, bridges, etc. which will require a lot more maintenance, and hence pollution to fix. At least 20% more road and bridge maintenance, I'm guessing is a lot of energy. Secondly, the tyres will require changing more often, along with other wearing parts, due to the increased stresses from the weight. What is the cost of this in increased pollution? Thirdly, how have the recycling figures been calculated? Does the energy required to recycle an EV leave out the parts that can't yet be recycled? What happens to those parts? Landfill? It would be nice to see a comparison of the percentages recyclable in EVs and ICEs. Fourth was the arguement about building new petrol stations and new charging points is about equal. This is ignoring the fact that we already have the petrol stations. The charging infrastructure will need to be comparable to the existing fossil fuel setup, which will take a lot of energy. I would also argue that a petrol station apart from a small electricity supply, is an independent thing, whereas charging stations need larger supplies of cables and infrastructure leading all the way to them. This is probably more pollution up front, at least. Fifth: there is the environmental cost of charging stations with regards to the space they require. I calculated that to serve the same amount of EVs (charged to about 80% capacity) as ICEs, charging stations will need about seven times the land area. Sixth is the drop off of efficiency with age, of both types of vehicle. An EV will need ot charge more often, after a while, which will affect the fifth point. I can never trust a report from people who have a vested, and possibly ideological interest in pushing an agenda. I don't mean you, Dave. Just the facts, Ma'am.😀

You raise a very serious issue. The government can legally decide that petrol or diesel fuelled ICE vehicles should cease production on any date they choose. What they cannot do is say they will be replaced by electric vehicles, because that choice is dependent on China. China controls around 80% of production of the rare earth elements that are required if you want to make an electric vehicle, a situation that isn't going to change significantly in the next 15 years. Neodinium, dypsoprisium etc. It's not planning laws that are preventing mines from being opened, it's the simple fact that the most economic methods of production of REEs is when they are a byproduct of a massive mine that produces some much less exotic element. China already has such massive mines - the USA don't, and there appears to be no way of changing that economically. And China are streets ahead in Africa in forming partnerships with governments who sit on vast reserves of any element they can't mine economically in China. It's not possible to manufacture an engine for Jet aircraft without Rhenium, because it will melt. Rhenium is essential because, along with other metals it forms an alloy that doesn't. It's worth mentioning that it isn't possible to recycle this Rhenium. Nobody has been able to come close to showing that it will possible to produce enough of the quantites required to manufacture all the EV''s that will be needed..

It makes intuitive sense once you learn two factors: - electric motors are incredibly efficient compared to internal combustion engines. it's eye-opening when you look at the maximum theoretical efficiency of ICEs and the real-world efficiencies of electric motors. electric motors are so much more efficient that it even makes sense (though the impact is less) to carry around a gas-powered generator to power those motors instead of powering a mechanical drive train, so hybrids get better MPG than gas cars. - bigger power plants (e.g. a giant coal-fired plant) are more efficient than smaller power plants (a tiny portable gasoline-powered engine) And then two more things that are just icing on the cake: - electrification makes it easier to switch over to green energy sources. you can't get gasoline from a windmill. - while battery storage doesn't make a lot of sense for grid storage, its portability makes sense for EVs. but once you have those batteries distributed all over the grid, you might as well offer rebates to EV users to let the grid rebalance itself with a portion (user-controllable) of that distributed battery.

Utility scale batteries help the grit out in a number of ways not the least of which is preventing dangerous power spikes or power dips that can damage equipment. Reading report of the Hornsdale battery there was times when they were getting power off the grid and getting paid to take it away at a dollar per kilowatt hour.

I looked at their methodology paper and was even more confused since none of the numbers presented in the methodology report lined up with the graphic. However, a simple question about the graphic is are we comparing apples with oranges. I get how you can compute gCO2/pkm for public transit like airplanes, buses and trains, but for private transport, it makes a world of difference if 2 or more people are driving in a single vehicle. Would the gCO2/pkm be a fraction of what is presented based on the number of people in the vehicle? For example, would a medium gas car with driver and 3 passengers be 48gCO2/pkm and thus actually lower than an EV with a single occupant? And what difference does it make if you are a foot passenger on a ferry or drive your car onto it? Seems like it will still burn the same amount of fuel. In order to make the right travel mode choice these "nuances" seem to be critically important. Thanks again for what you do - invaluable to us all.

I’ve driven an EV for nearly 4 years, so often have conversations with all sorts of folks about the merits of ownership. I usually tell them that EV’s aren’t really “green” as no manufactured product can really be green. However, modern society has managed to build a reliance on the car that would be almost impossible to completely reverse, in that respect EV’s are a much better option than using a fossil fuelled vehicle. I started installing solar panels to supplement our energy use some ten years ago, an effort to reduce costs with the knowledge that electricity can only get more expensive. Over the years I’ve added hot water heating and later an EV to the equation. For our normal day to day driving all our charging is covered by the excess solar production, a significant saving over fossil fuels, especially now the price has risen so sharply. I appreciate that not everyone can afford an EV and solar setup, but this didn’t happen over night, it was gradually built up over a decade. We recently sold our Kona EV after 3.5 years of ownership and 67500km, only 1500 euro less than we paid new. We have completed several European road trips, at roughly a third of the cost of running an efficient (4km/100km) diesel. If you can charge at home an EV makes a lot of sense, for those that don’t have that opportunity I’d suggest an EV with a long range and checkout very carefully the local charging facilities, or ask if it’s possible to charge at work if you commute by car. Hopefully governments will take more seriously the need for charging facilities to allow the rest the opportunity to own and charge an EV, waiting for fossil fuel companies to provide this seems a bit stupid to me, where is their incentive!?

@@H4N5O1O I think I see where you’re coming from. But it also sounds very very out of touch. Consider that the device you are using to read this only exists due to globalized shipping and trade. Also, it’s impossible for 100% of the population to live in an urban environment with walkable access to everything they need. Food doesn’t come from a grocery store. It comes from farms. Presently it’s only the smallest percentage of the world’s population that is affluent and privileged enough to have everything brought to them rather than the other way around. And the former are merely outsourcing their long trips to the less affluent. Please describe a means of creating a world where this kind of inequality doesn’t exist. I’d really like to know.

Thanks Dave for another wonderful video. We make energy block diagram for every product, every process. The variables can be added to the diagram as they emerge. Finally we could bring up something that is most green for individual transport. Have ICE vehicles, two wheeler or four wheeler, run them either on ethanol or biodiesel made locally from agricultural and municipal waste. This model can work wonderfully for an agricultural country like India, China and most of South East Asian nations that house 50% of world's population. Economic consequences can be disastrous if people are able to brew their own fuel.

Wonderful video! :D I would like to point out that the BEV batteries production CO2 costs are based on Lithium Ion batteries that use cobalt and nickel which produce 50% more CO2 per battery than Lithium Iron Phosphate batteries (LFP). LFP batteries also last 3 times longer which means for ever LFP battery produced you must produce 3 Lithium Ion batteries that use cobalt and nickel. So the Lithium Ion batteries production generates over 3 times as much CO2 than LFP batteries.

Doing nothing at all is definitely not the best option, and yet a great deal of effort is going into protecting the investments of those committed to doing nothing.

For the 25% transportation and other items shown at 2:06 these are competing proportions I found here and there from legitimate looking sources in 2014: In 2011, fossil fuel use created 33.2 billion tonnes of carbon dioxide emissions worldwide. CO2 (carbon dioxide) emissions sources 87% fossil fuels 9% land use changes 4% industrial processes Details are: CO2 (carbon dioxide) emissions sources 36% electricity & heat generation 17% industrial 14% transportation - except motor vehicles 9% other various 9% land use changes 8% transportation - motor vehicles 5% residential 4% industrial processes (cement production, maybe others) I've heard 8% & 9% for motor vehicles transportation but there's slight variation in information on all of the above of course. Here's a competing but similar assessment: 41% Electricity & heat generation 22% transportation 20% industrial 10% other 6% residential The 87% carbon burning emissions sources of CO2 are: 43% Coal 36% oil 20% natural gas CO2 emitters by national grouping China 23% USA 19% European nations 13% India 6% Russia 6% Japan 4% Canada 2% All other 28%

Thanks, I think you're referring to the IPCC 2014 analysis? One difference in the videos pie chart is it's not considering energy production as a separate slice; presumably it assigns the emissions to the economic sectors making use of that energy.

New to your channel. I saw the title of this episode and expected the "school yard" approach. Cherry picking data points. I was wrong in my assumption. You have a shiny new subscriber. 🙏

Nice review and summary. The ICCT paper just reinforces the uncontroversial consensus that an efficient EV powered by a grid with an increasing share of renewable generation is better for the environment. Researchers at the universities of Exeter, Nijmegen and Cambridge concluded in 2020 "Electric cars better for climate in 95% of the world": "electric cars lead to lower carbon emissions overall, even if electricity generation still involves substantial amounts of fossil fuel." And the Union of Concerned Scientist has been doing similar analysis for years: unless you barely drive a 50+ mpg hybrid in coal-soaked West Virginia, get an EV. It's intuitively obvious once you do the math and to find a 35 MPG car will burn through 10 TONS of actually filthy gasoline over 120,000 miles, which turns into 33 tons of CO2. Adding a 1/2-ton recyclable battery to make a far more efficient BEV reduces that significantly, no matter how much fossil fuel companies try to whip up fake "But what about the toxic polluting battery mined with children's bloody fingers?!" hysteria. Making then burning petrol is WORSE, and a gasser burns through a lot of it.

The best car is no car.

Unless you live and work in a place that enables you to travel everywhere by pedal cycle, local public transport and national rail, then EVs are a total no-brainer. Not just for the environment, but simply as a vehicle to drive. They are a joy to use: quiet, smooth and fun. It is unbeleivable that we are prepared to keeping buying both the fuel and the bullshit the fossil fuel companies sell.

you're forgetting the up front cost of an EV. currently they're way too expensive for many people. you can buy a decent used gas car to get you to work for 2-3k.. how much is the cheapest reliable used electric car? how about if you need a work truck or contractors van? in the coming decades EVs will be more widely adopted but right now they're still financially out of reach for many.

a no-brainer when you live in a privileged normal country, where I live people would have to work around around 50 years for a EV but they have to eat so saving money for a EV actually takes from 300 to 500 years.... and when that thing brakes there's no way a normal joe will fix it, you have to go to a dealership and pay with your kidney, meanwhile old petrol cars are easy to fix in your shed

Great video on the carbon emissions side of BEV vs Gas/diesel transport. Anyone have a good resource to look at the 10-15 year 150k-200k mile economics of gas vs electric? I know the situation is changing rapidly, but im interested in the forecasted costs (including battery maintenance/replacement) over time.

had an opportunity to get an e-bike and it's great for getting back and forth to work and small errands. car is parked much more often, gas bill is way down, and getting a bit of exercise in :)
