Kudos for acknowledging the mistakes! Takes a pair to pull off! Given the climate I live in and huge distances involved in routine trips, EV will never be an option here simply from survival standpoint. I often have to park off the road during blizzard and wait the blizzard out inside the car (with the engine off - obviously - i have layers to survive -40 'F inside the car just fine). With the gasoline car, I know that I can simply wait it out, sleep in the car and survive. Try to take a wild guess how long will the EV battery last at -40 'F/ - 40'C and whether the car will start after , say, 8-10 hours out in the elements (full exposure to wind-chills down to -60 'F), especially after having driven 200-300 kms already, but if someone's aspiration is to win a Darwin's Award, hey - no judgement there :) That being said, EV could be a nice, fourth (not second, not third) summer car. I can see it could be used for about 3-4 months out of a year, probably 2, perhaps even 3 times per week for things like - getting an ice cream, picking up mail or visiting neighbors across the street :) On a second thought, for $80,000, I can probably imagine a nicer summer car than a typical fugly EV...

(Which in your case would be a problem, I agree) But sodium batteries are coming and they work with close to 100% efficiency up to -20°C. Even at -40°C I'd expect them to work decently well, but time will have to tell there. Does your combustion car even start at that temperatures? Don't they need a block heater at that point?

Hi Sabine, your mind set for AC home charging is based on combustion engine fuel tank refills. You go to the service station when your fuel tank is low. With an electric vehicle you top-up charge every time you drive into your car port or garage. On average most daily distance covered by a vehicle is less the 50km. This would require approximately 4 to 6 kwh of charging energy. With a 15 amp AC socket this will take approximately 2 hours or less. If you have solar and charge during the day the cost to do so will be small or nearly free. It's great having control of your own electric fuel supply at home. Will never go back to ICE vehicle.

I fully agree on the fuel tank refill analogy @henvan8737, several times during the video I found you, Sabine, try to apply "old-style" (i.e. petrol/energy) mindset one to one to BEVs. Another example is peak loads for the grid (transformers). This assumes energy generation and distribution will remain forever centralized, but we already see a disruption there happening right now due tue exponentially growth of renewable energies. So, yes the grid needs to change and become more flexible but mainly due to renewables and not BEV. And again, this is already happening. There are smart home chargers on the market which charge your car whenever there is cheap electricity (and low load to the grid). Also, every BEV and home owner will add solar to the roof, for purely economic reasons, thus effectively reducing load to grid. Not to mention vehicle to grid which you can already buy in some countries (e.g. in Germany: Volkswagen - E3DC) All of that (and more to come) is reducing load to grid and is part of a transformation, that is happening anyway due to solar+wind even if no BEV would exist on earth...

As a new EV owner, I was warned against daily charging. There is a limit to the number of times a battery can be charged. Topping off your EV battery is similar to keeping your phone or laptop always plugged in. It reduces the life span of the battery. I was told to use the battery for what it was intended. I drive my EV down to a charge level where the remaining distance is at or below 50 miles, unless I plan to drive a considerable distance. Then I charge it up to 80% to ensure I can make it back home.

Ech time it starts the motor and system efficiency is almost ZERO!!!!

Hi Sabine! I've been driving my Tesla Model Y since June of 2021 and my experience has been as follows: - I never think about going to a gas station. No more calculating if I should stop at a gas station before or after my next destination (or wait until tomorrow). Just plug in at night and forget about it. - No more standing outside in the wind, rain and cold to fill up the tank. - On the rare occasion I do need to use a Supercharger, just plug right in. No swiping your credit card as the charger knows who you are and knows how to bill you. - Driving is tireless as I rarely need to use the brake. Letting off the accelerator automatically switches to regenerative braking which slows the car to a stop. No more switching your foot back and forth in slow traffic. - Tesla service staff comes to my house for certain service calls. Recalls have been handled via over-the-air software updates (thus far) - Charging costs less than half the equivalent gasoline (according to the app). Easy to configure off-peak charging.

We have been driving a Chevy Volt for 6 years. 90% of our charging is at home. Often you don’t use 100% of the power and don’t need to charge every night. And the big omission in the revised version is the cost savings of routine repairs. In six years: no brake pads replaced, no electric motor adjustments, no battery maintenance! Sure, replacing the whole battery would be expensive, but that is more like replacing an internal combustion engine rather than a gas tank. It happens, but very rarely. In my experience, the vast majority of EV drivers would never go back to the high cost of gas and routine maintenance. Thanks for asking for input Sabine. Your integrity is showing. 😊

Dear Sabine, thank you for all your interesting videos. YES, I'm driving an full E-vehicle, and that fact came in my life with different other events, all of them making sense together. First of all; I bought this car when I was 67, and liberated from professional pressure (I'm not sure it would have been possible if I was 40). Second point: I finally became strongly conviced about climat change and the absolute need of decarbonizing our lives. What means: accepting change, accepting reduction of expenses, reduction of consumption. What means: reduction of mobility. I don't fly anymore, I stopped eating beef, and try to convince my neighbours and family about reduction of green house gasses emissions, what is a sometimes a painfull challenge. So, I bought a LITTLE e-vehicle (Opel Corsa). I therefore abandonned my dream of driving a beautifull Volvo XC40 (abandonning dreams is also challenging). I charge aat homs, at night, and don't drive mors than 200 km/day. Living in Belgium, a little country where everithing is close to you, makes that not too difficult. For longer distances, I stop using the car and take the train. Decarbonizing our lives is an absolute piority!!!

Even if I did the infrastructure for charging out here is simply not there and the distances we have to travel are far greater than you do in Belgium. This push for carbon reduction is in my mind at least 30-40 years too late something should have been done about it way back then.

Well done, Sabine. You managed to discuss electric vehicles without mentioning the shortcomings of the currently dominant EV power source, namely lithium-ion batteries. Leaving aside the whole raw materials issue and the fact that Rio Tinto, the world's largest mining company, said at a recent industry conference that there simply isn't enough lithium in existence to meet demand, there's the issue of the chemistry. While the dangers of Li-Ion may very well have been overstated, the fact is that they have very real consequences on the motor trade. Among them: The escalating severe depreciation of EVs that can now be measured on a weekly basis; the scrapping of battery packs with only superficial damage to the outer casing (which usually means writing off the entire vehicle because of the cost of replacement); the refusal of used car dealers to take them as trade-in or to buy them at auction; the increasing reluctance of insurance companies to insure them and steeply rising premiums for everyone, EV owner or not; the inability of local mechanics to repair them because, amongst other things, manufacturers (especially Tesla) refuse to supply them with parts because they are not authorised repairers; and the increasing unwillingness of body shops to take in crashed EVs because of the danger that a damaged battery pack will ignite and burn everything to the ground. Note that I haven't even mentioned all the problems with battery disposal at end of life. As things stand, spent Li-Ion batteries go straight to landfill because they cannot be recycled and that means that they will be oozing toxic chemicals into the land and water for decades if not centuries to come. Battery electric vehicles are an environmental disaster in the making. In fact, it's already happening in China. Maybe in the near future solid state batteries will arrive to save the day but right now what you have is a bunch of scientifically illiterate politicians pushing a suicidal agenda that will do lasting environmental harm down our throat for the purpose of establishing their green credentials.

Well put, it's nice to see a voice of criticism during this, what some would call, mass schizophrenia event. 😢 I would add another point, regarding safety. In case of accident, or catastrophic battery failure one is dealing with a fire that is hard to extinguish. Since battery burns independently from oxygen supply, conventional methods and extinguishers are u effective. Fire itself is a chemical reaction that will run its course for anywhere of up to 36 hours. As we already know, although rare, spontaneous ignition of a lithium based batteries happen. Imagine one of such EV, being parked in the underground parking of apartment building. That just might be a reason to insurance companies behind reluctant about EV. Recycling of batteries is a big issue that no one wants to talk about. Public is well attuned and oposes nuclear waste storages while turning the head other way when we have similar r problem but on much bigger scale with all renewables. In fact recycling is the biggest problem of all renewables. Recycling is a daunting, ridiculously expensive and notoriously not included in energy cost forecasts. Why? Because then they would be totally unappealing solution, as EV are now. Same goes for solar panel and wind turbines on a smaller scale. In general all prognosis seem to be well to optimistic, loke not even taking demographic decline as factor in near future. This obviously not popular opinion in the doctrine of climate change. Don't get me wrong, let's get off fossil fuels but in a sensible, not a reckless way. Imho, by the way and means of introduction, lack of sensible debate and exercise in scaremongering, whole industry smell fishy to say the least.

Great review Sabina. I am basically an environmental petrol head! Our home is now fully self sufficient for power water and outputs. We are actually on our second complete solar system. Technical efficiency has improved dramatically over the last 18 years and costs fallen dramatically. Our new battery hybrid 8.6kw system cost less than our original 2kw system! Everyone said back in 2009 when bought our Prius ITech that the batteries wouldnt last that it wasnt viable etc but the main batteries are still original and operating to specification. The only thing replaced was the inverter in 2022. So full EVs will be both better and worse than people expect IMO. There will always be a fundemental issue where mass is involved. For hauling loads long distance EVs cannot compete with efficiency of the modern Turbo Diesel. And so people are going to be faced with transformative change. Travelling long distances hauling caravans or trailers will be much more difficult. When you consider that the most popular new vehicle in Australia and the USA is 4wd SUV utility many are going to find change difficult.

"For hauling loads long distance EVs cannot compete with efficiency of the modern Turbo Diesel. " I agree ! I bought a diesel car precisely for that reason. But that is only for a transition period. New battery technology will be mass produced end 2023-2024 (CATL & BYD) with a range of 750 miles/1000Km and charging from 10% to 80% in 15 minutes. The technology is improving fast, and mass production takes less than 2 years now. So I bought my diesel car because my old diesel is not allowed to drive in the city due to political "environmental" reasons. I therefore needed a solutiion until 2027-2028 when the EV with a longer range faster charging batteries will be available, and affordable.

And even more importantly, we don't all charge from 20% to 80% every night. These calculations need to also include the average distance people drive each day and the average energy consumption of the EVs on the road to calculate the amount of energy needed to charge every night. And they never take solar and home battery uptake into account. I pretty much only need to charge once a week, and I do that from solar on my house, mostly on weekends. Most people doing the work commute will find one or two charging sessions a week will meet their needs easily. If your workplace has the sense to go solar and provides charging infrastructure for employees, then the problem goes away. All the talk about grid infrastructure needs is often partly driven by grid companies seeking to profit from investment in their networks. One of the real drivers of cleaning up our energy systems will be decentralisation, ideally behind the meter, through solar and home storage (and stationary batteries are a much easier target than mobile ones from the resource perspective). Some sensible investment, through low or no interest loans for people to buy locally manufactured home batteries would go a massive way towards grid resilience. Oh, and we get increased domestic security as a byproduct by massively increasing the number of targets an adversary has to hid to cripple our energy systems, and by onshoring more and more of our energy sources.

"Time/energy to charge to 100%" is a completely irrelevant metric. EV manufacturers need to start advertising in terms of miles/hour of charging instead of whatever the hell they're doing now. My 2018 Leaf is 250km on a full charge of 40kWh, which means it charges 60km worth per hour on a Level 2 or 12km worth per hour on a standard 120V. If you commute to work every day and you spend only 10 hours at home, you'll still be able to top up every night plugging into your wall socket as long as your commute is less than 120km both ways. As far as charge times goes, that's literally the only figure that matters.

We have two cars at home and one is a BEV. We have a garage and a nearby 240V outlet. If you plan on replacing one of your cars and can charge it at home, you have no calculations to make. If you can supply all the charging yourself it is absolutely a no-brainer. Even if you have no environmental concerns, do it for the money. I am saving well over 50% of the total previous household fuel costs. We got the new car last December. I have tried quick changing on trips but in Costa Rica, it is still far from dependable. I plan a longer trip to a rural area for the end of the year. That trip will be in my old car.

(Recently retired from a Fortune 100 US electric company) The big time factor in building new transmission lines is acquisition of the right-of-way. The process often has a lot of dead ends, so the negotiations typically start with getting past choke points. Only after those are identified and commitments acquired can the less challenging parts be negotiated. NIMBY - Not In My Back Yard - is still a problem, as is the perception by potential sellers that they have a unique commodity. 15 years is remarkably fast for these projects. The other infrastructure concern is electric availability: enough generation at the moment to meet demand. The load/generation curve commonly called the "duck curve" illustrates the breath-taking shortfalls in generation at sundown in particular areas like California and Hawaii. Today, the focus is rightly on grid level storage. Using EVs for storage is a distant possibility: their status is never known (are they full or empty? Will there be fewer or more tonight than last night?). None of these are insurmountable problems, but they are facets of the folly of politics driving the pace of changes. We can get there - whatever "there" actually looks like - but not nearly as fast as we might like. Fifty years would be very optimistic; 70-80 years more realistic. It is likely we will find we have made quite a few wrong turns on the way. I only know for certain when we get there we will marvel at how naive we are today.

I'm glad you pulled the other video, it had a huge number of serious mistakes in it. This one is much better. I'll make some additions, simple things that people can remember: * A good rule of thumb for passenger-vehicle EV power consumption is 3 miles per 1 kWh. Tesla's get closer to 4, but 3 is a good conservative rule of thumb). From this it is easy to determine how much electrical energy is required, since statistics on miles driven are readily available and each individual has a pretty good idea how much they drive. * So in terms of charging at home, the charge rate you need for convenience depends entirely on the above. If you drive the average round-trip commute of 40 miles a day, you need (40 / 3) = 13 kWh worth of charging each day. At a space-heater rate of 1000W (1kW) this would take 13 hours with an L1 charger. With a L2 charger set to 16A it would be (16A x 240VACrms = 3.84 kW, so (13 / 3.84) = 3.4 hours. At 35A, even less time. For home charging, thus, it comes down to what is convenient for the consumer. A good rule of thumb is "overnight charging". L2 chargers are more convenient but to be very explicit here there is no need to charge at 35A. You can easily charge at 16A or even 8A or whatever, so being circuit-limited is not that big a deal. And if it came down to it, you could charge from a normal consumer outlet (120VACrms in the U.S., 12A = 1.4kW, or (13 / 1.4) = 9 hours to charge 40 miles. * This determines, more or less, how dependent on fast DC charging one is. If you have no outlets at all, say you park on the street and can't string an extension cable without someone getting angry at you, or if you drive a lot but can't get L2 charging, or if you are driving long distance all in one go, such as when taking a trip, then you need to use a fast DC charger for at least part of your trip. Most people do NOT need to use a fast DC charger for nominal work commutes. Not to mention that there is also such a thing as "destination charging" which is typically built-out by businesses that more and more EV commuters will be able to use over time. * This means that Fast DC charging is really only necessary for longer trips. There does need to be a build-out, and Europe is way ahead of the U.S. on that, but it isn't really a show-stopper. That is, there will be push and pull just like any other build-out, but it is not necessarily something that needs to be 100% government funded. Demand creates supply creates demand. -- This time around you made only two significant mistakes worth noting: (1) The first was confusing what parts of the grid have to be upgraded. To be clear, the ENTIRE EV rollout can occur with only minimal distribution-side upgrades and, in fact, no home services need to be upgraded. Sure, it might be convenient for some home owners to upgrade, but it is absolutely not a requirement for any home. The serious upgrading of the grid has to occur on the generation side because the renewables generation expansion is "a larger number of smaller generators" and those generators need feeders and backbones. That's 99% of the problem. Feeding residential power back to the grid does NOT require distribution line or transformer upgrades because backfeeds are limited to 20% of the service size anyway, which is less than peak consumption. But it MAY require a substation transformer upgrade... mostly the reason for this is to upgrade to a transformer with better voltage regulation automation. substations transformers have various taps that the substation can switch them between to change the voltage ratio of the transformer. When feeding power in the reverse direction, the voltage is being scaled up rather than scaled down and if a large subdivision is pushing a lot of power it is generally doing so near the top of the allowed voltage range. Which means that the step-up in the reverse direction can sometimes exceed the substation's intermediate voltage rating. Hence the need to upgrade that particular transformer. Distribution (e.g. pole) transformer upgrading is only a function of potential peak charging rates which for EVs can be significant, except that there is no actual requirement that an EV be charged at 35A. It can just as easily be charged at 8A or 12A or 16A, for example, which are far less stressful on distribution transformers. So is it actually a show-stopper? No. Just a convenience. The utility can simply require that homes with un-upgraded equipment charge at a slower rate until such a time as the equipment can be upgraded. That's it. That's the technical explanation. But it should be noted that substation upgrades are only required piecemeal. The entire substations / all substations do NOT need to be upgraded because neighborhoods just don't all upgrade to solar, let alone reverse EV feeding, overnight. The quoted dollar amounts or spectacularly over-estimated and completely ignore the dynamics of the rollout and adoption of EVs as well as the 30+ year time-frame involved. When you divide it all out, it really isn't as much money as people think it is. (2) You, like a lot of people, greatly misunderstand the power of industrial scale in production when it comes to the cost of building an EV. This is the primary mover. You also are still a bit behind on understanding battery chemistries. Cobalt and Nickel are used in NMC and NCA chemistries, but are NOT required in LFP chemistries (you mention LFP later but you clearly got lost on the significance). So neither Cobalt or Nickel are show-stoppers. Lithium is a very abundant element all over the world that requires only the mining to be scaled up. That is happening. Just because there is some push and pull doesn't mean that it's actually any sort of problem that would stick with us. You mention LFP, but you are a bit behind on the chemistry. Adding manganese (LFMP, for example), and other similar adjustments, has brought the energy density up to near the same levels of lithium ternary batteries (typically NMC) and this is clearly where the market is headed. Sodium batteries are NOT in scaled, volume production yet. LFP batteries are. Sodium batteries are a bit behind on the technology scale but they could very easily grow into a competitive alternative. == That's everything in a nutshell. You did a much better job this time around. Just remember that the technology is progressing VERY quickly, which means that you have to keep up with it at the same pace.

Thanks so much. One additional comment, not aimed at our dear Sabine in particular. Many alarmist EV discussions are "Oh my, EV' transition is such a huge problem, where will we possibly get XYZ materials!!" They completely leave out the alternatives. The growing demand in developing countries for more and more transport, in addition to more developed countries replacements. Without EVs, the world could not meet the much greater XYZ material demands and inefficiencies with ICE transport. EV's are already getting much more recyclable, for example. Fewer parts. Less pollution in use. Less pipeline and refining buildouts. Less oil spills. Fewer tanker trucks on our roads. Less sea bed drilling blowouts. Etc. The past and future environmental devastation caused by fossil fuel use MUST be included in any critical discussion of EVs.

The dollar amount of the upgrade to the grid is also overestimated because that upgrade is INSTEAD of normal upgrade that would have been done in any case during those same 30 years. The needed upgrade might cost more, but it's not all ADDITIONAL costs. But I can understand why estimating that is more difficult (it also depend on how much investment in grid maintenance is done by different utilities and that is very different in different countries)

I thought the main problem with Lithium supply was all the water it uses in the pools, Matt Ferrell (@UndecidedMF) did a video about companies trying to extract it in different ways but it didn't sound like they were near commercialisation yet. I agree about the grid, there is a lot of alarmist reporting out there, normally from media with big fossil fuel sponsors. 🙄 There are bound to be areas where the infrastructure has been ignored for too long and will need substantial investment, then there are areas which are already ready. I can't afford Patreon so I don't have access to the references, I was wondering how much charge was needed for each vehicle in the estimations at 10:20, not a question for you but something I wondered while listening. I didn't think many people drive further, every day, than a standard power plug can provide overnight, assuming people plug in when they get home and not the moment before they fall asleep. I think most of us spend more than 8-9 hours at home before leaving again. If they can get a V2G standard widely adopted they should be able to use the "smarts" to distribute the load around so nothing gets exceeded and everyone has enough charge for the next day. Of course this will require people to think ahead and set how much charge they'll need for days they'll travel more than usual, so it's probably headed to massive online and talkback radio bitching!

I'm very bullish on sodium-ion batteries. They probably won't be in long range cars anytime soon or ever, as they are competitive with LFP and some day maybe even with NMC in Wh/kg, but not Wh/l. But I think they will be in all low to mid range cars at some point. They just have amazing properties compared to existing lithium-ion batteries. While they are in mass production now, it's not at a big scale yet, that is for sure. CATL is very clear that current lithium-ion battery factories can be easily converted, but that is of course only half of the story. The materials used are completely different. So building up supply chains could take years. But let's hope it goes a bit quicker than that.

@@Cluuey the water that is used up in lithium mining is brine from salt lakes in which nothing can survive and that can be used for nothing else. Compared to mining other metals lithium is basically planting trees to grow back the rain forest or something like that. There are people saying that it magically makes fresh water disappear, but that doesn't make any sense. It's more likely that that is due to the big cattle herds in the area. If tens of thousands of cows are drinking water in a desert for decades, at some point there won't be any water left. Where is it supposed to come from? Rain? It's a desert.

From many perspectives an excellent presentation of the situation, but Sabine! You once again omitted an extremely important point! Cars, electric or otherwise, are designed for things they are statistically never used for. Cars are driven short (

Since you asked, I’m driving a Subaru Solterra in Japan, and so far am absolutely loving it. The public chargers, while not ubiquitous, are at least common and have even some 100% free options if you’re willing to visit a public park in Tokyo. A quick charge at a highway stop is ¥800 with a ¥4000/mo membership fee, or double that without (break even at 3 charges/mo) and several malls such as those run by Mitsui and Aeon have chargers, some of which are free and only cost parking fees, which of course you can also waive by shopping. Many smaller shops have public chargers with the same card system as the highway rest areas, and if approved, businesses can install them completely on the government dime, equipment and construction both, if they’re available to the public, even when payment is required to use them. I have encountered situations where I couldn’t use the specific charger I wanted, the high amperage chargers are taken first of course, but I haven’t this far encountered a situation where I had to queue for an available charger. Then again, I only took delivery of the car last week, there’s plenty of time yet to be inconvenienced by the bad manners and whims of other drivers. The standard highway charger is 50kW, which can be awkward in a Solterra with a 71kWh battery. Public rapid chargers limit you to 30 minutes per use, and so while they add about 140 km of range, they in no way will push the battery from 20% to 80% in a single charging session. This is where my preference for said higher amperage chargers is from, and yet some infrastructure is as low as 25 kW, though that’s not typical. The one thing I do really like about the public charging infrastructure is that there is real-time usage reporting. From either an app or my car navigation, the available, usage or out of service state of chargers is visible, and my car at least lets you restrict searching to available chargers only. All of that is subject to change of course, but that’s been my experience thus far.

Your videos are so great. I drive an EV, Volkswagen, and live in a cold climate. The most difficult thing that I didn’t anticipate when making the choice of which car to get was the significant, almost 40%, reduction in range when the temperatures are cold. It makes the effective range considerably lower than advertised for almost half of the year.

I’ve driven a plug-in hybrid for the past four years and a full battery electric for one year. I also have a solar array on my roof that generates a surplus, so my charging costs are very low. In my experience, the full electric vehicle requires some changes in lifestyle and planning to avoid prematurely degrading the battery or running out if power on a road trip. My plug-hybrid requires almost no change in ordinary habits, except for what is perhaps the most important feature - - home charging - which means only having to visit a gas station for long road trips with 90% of local driving powered by the battery. My full battery electric car is fun to drive and I’m happy that I bought it. But for the average household, I think that a plug-in hybrid with at least 40 miles of range is currently the best option.

I have an electric vehicle, solar panels and a remote job. I charge my car during peak sunlight hours. Remote work is something we should be pushing to help the environment.

Thanks for a great video Sabine. I’m using an EV since 2020 in India. At that time there were few fast chargers on the highways so had to request restaurants (Dhabas) on the way to plug in my portable (very slow) charger and order endless tea (chai) and pakoras! That situation has changed rapidly with many fast chargers on the highways set up by different power companies. At home, I put solar PV (grid connected with net metering) so now my car, AC cooling and cooking is practically free and green. Going by the immense change I have seen in India, I am more optimistic than your video!

My wife and I drove ~10,000 km from the Vancouver BC area to southern Ontario and Toronto and back again in early May, in our Tesla Model 3 with an LFP battery. We had no problems during our drive, when we relied on the Tesla Supercharger (DCFCs with the Tesla NACS plug) network, and averaged just under 1000km/day during the eastward portion of our drive and our best time was just under 10 hours to drive ~950km and that included charging stops! We averaged about 7km/kwh for the whole trip. I bought the Model RWD with the LFP battery because it is the most efficient electric car available and because Tesla has introduced an adapter so that most newer Teslas can also charge at non-Tesla DC Fast Chargers (DCFCs with the CCS1 plug) which greatly increases the number of fast charging stations available, especially in rural areas. We usually charge at home but the availability of DCFCs makes long trips quite feasible. The DCFC charging network is rapidly expanding in North America and we had no problems driving from BC to SE Arizona and back again, last winter.

Your reasons for your car choice were the same as mine! I took delivery of a 2023 model-3 rwd on last November 28. I charge at home (7 kwh). In December we traveled from Michigan to Tennessee (670 miles), charged 4 times at superchargers. I'm spoiled, haha! Last Sunday we drove north 67 miles to visit friends, ate, saw a giant Sequoyah tree... drove home and still had 102 miles left.

The point "good luck finding a charger outside of Paris" has a lot of missed detail. Generally speaking, public chargers only have relevance in cities where people who live in apartment buildings with no garage may live. Anybody living semi-rural has a garage or a parking space, the cost of installing a level 2 charge is cheap compared to public charger rates, and will almost exclusively charge from home. Those who don't match this pattern will likely not buy an EV yet until some condition changes. As a long-time rural resident who drives 15-20,000km/year, I use a public charger less than once a month, and I use a DC fast charger around once a year. If you have a garage, you charge at home, and the whole first part of the video is irrelevant. Another missing detail is that if you have a roof, then installing solar and charging from your own sunlight is a financial no-brainer. Compared to energy rates or public charging prices, a solar system on your roof is a win, and that leads to zero-carbon charging for some fraction of EV's. Predictions and estimates for costs and quantities never seem to account for a large section of the EV ownership and charging patterns. Nobody I know who is an early adopter of EV's doesn't have solar and doesn't primarily charge from sunlight.

I have a 2023 Mustang Mach E. I have a 40 amp, 240 volt charger (9600 watts) that can bring the car up overnight without fail. For 99% of the driving I do, it's all where I can return home without charging and charge at home. I schedule the charging between 11PM and 6AM where the grid is fairly unloaded -- the car allows one to specify charging times. My battery chemistry is NMC, and I normally charge to just 80% unless I'm doing a longer trip. I absolute love the car. Great video and seems very complete. Thanks.

I have been driving electric since 2012 and my family (2 cars) exclusive electric since 2014. We driving ~ 12k mi/year in each car, go on road trips, etc everything typical people do with cars. The picture you present does not reflect my experience in North America with Tesla; Superchargers are generally widely available and very VERY dependable (unlike the competition- a question of incentives) and home charging has been a complete non-issue. My other beef with your exposé is that it leans to heavily on the current state of things. Ford CEO not withstanding, battery prices _have_ been falling dramatically over this decade. Final thing that was frankly ridiculous: repair cost. Fact is: the maintenance of our Teslas have been far far cheaper than the ICE cars we had previously. And they are cheaper to operate (I have records to prove this).

I'm driving a used Tesla since 2018 that replaced our big car for the long trips. It had around 200.000km on the odometer when I bought it and it is still doing great. The battery is far from dying.

Correction: Nearly all homes in the US have 240 VAC. For most circuits that's split into pairs of 120 VAC. But high-power appliances in the US use the 240 VAC. That includes electric furnace, air conditioner, water heater, and clothes dryer. People who want a car charger at home will need to have an electrician install a 240 VAC circuit and a charger at a suitable location ... in the garage. It's expensive. The bigger problem is that many homes don't have an adequate service connection. Older homes might have 100 amp service. But regardless ... if the service connection was merely adequate for a pre-EV world, it's often not adequate with the added load of an EV charger. Upgrading the service connection is VERY expensive. And it's often impossible because the electric company might not have adequate power available at the nearby transformer.

At around the same time I had 40 solar panels with a peak output of 15.5kW fitted on my house roof and 45kW of battery storage. The latter was necessary in the UK because most houses only have a Single Phase supply, feed-in is therefore limited to 4kW and I didn't want to throw away available energy. 4kW is a ridiculous limit to impose. The peak output power from the panels had been factored to extend use of home generated electrical energy into October and March. Apart from longer journeys when I have to use fast chargers the car runs on home generated solar energy. I don't suffer 'Range Anxiety'. I plan journeys beforehand, use Eco Pro on the i3 by default and on motorway driving often opt for slip-streaming large lorries. The whole exercise has been fun (80% of the time - when my wife is with me she doesn't care for the risks I take with range but the closest we came to running out still left us with 3 miles when we reached a charger - she was not happy). I would certainly never go back to an ICE. I would say 70% of my mileage costs me nothing in electricity because it's "free" if you ignore the investment I've made. Why did I do it?

Urban planning, mostly. The typical modern city - especially in the US - was really built around the car. There are zoning rules that separate residential and commercial areas, so there isn't anywhere within walking distance - all shops and workplaces are in a different part of the city from the homes. The road layout is made to maximise efficiency for car transport, with little regard to cyclists or pedestrians. The suburbs are especially bad, as their population density is too low to even support public transport - the houses are spaced so far apart that no matter where you put a bus stop or subway station, there wouldn't be enough people in walking distance to support it. If they could even reach it without having to cross dangerous six-lane roads. Public transport and walkable/bikable cities would be great, but it's hard to undo a century of city design. Politically difficult too, in that you'd have to change a lot of laws which still have public support: People like the comfortably spread-out suburban sprawl where they can live in a mini-mansion and be happy that none of the icky poor people can afford to live nearby.

As Tony Seba and others predicted, solar and wind power is growing at an exponential rate. If it really is a problem to have transformers working at night, then we simply need time-of-use pricing on electricity that encourages charging at the optimal time. In places with a lot of solar power installed, there is the famous "duck curve" where power is pushed onto the grid when it's sunny whether there is need for it or not; in such places, if the rates are cheapest during the day, people would be encouraged to charge their cars during the day and that "duck curve" power will be more likely to be put to good use. In the long run, electric transportation will reduce the impact of humans on the planet. It's true that it takes more minerals to make an electric car... my car has a battery pack that weighs around 1200 pounds (545 kg) and that battery pack holds 100 kWh, about the energy of 3 gallons of gas (11.4 litres). Yet the EPA estimated range of my car (when new) was 335 miles (539 km)! And that battery pack should work for at least a couple of decades, and then will be recycled, whereas fossil fuels, once burnt, are not only gone (needing to be totally replaced) but also add pollutants and carbon dioxide products to the atmosphere. Compare that battery pack weight with the weight of gasoline: I've computed that my old VW station wagon would burn about 3600 pounds of gasoline (1633 kg) each year I drive it. If we assume my electric car lasts 20 years, it (including all the minerals in it) would prevent the burning of 72000 pounds of gasoline (32660 kg)! Then consider the second-order savings. Gasoline is made out of atoms and must be hauled around: tanker ships bring crude oil, refineries make gasoline, trucks deliver gasoline to the filling station. In contrast, electricity flows through wires. (And I make most of the electricity I need from the roof of my house.) I've read that 40% of all ships on the ocean are hauling fossil fuels around (oil, natural gas, or coal). When the majority of our energy used is electricity, and the majority of generation is renewable, the pollution and waste associated with the fossil fuel economy will mostly disappear. Electric cars are a rare case where doing the right thing is no sacrifice. My electric car is the nicest car I've ever owned. The only thing wrong with it is that it cost a lot up front, but it's extremely inexpensive to operate it. (Especially considering I live in the state with the most expensive gasoline in the USA, but relatively inexpensive electricity. And once my solar panels are paid off, I'll get a great deal of electricity at no further cost to me.) I would be happy if all new houses were designed and built to have solar power generation on the roof, and a ground-source heat pump for heating and cooling. It will always be less expensive to design such things into the house and build at scale, than to build houses without them and retrofit later. And people won't mind the cost of solar or the heat pump if those costs are rolled into the mortgage.

Good lord, where to start on your comment, and do I even want to bother. There is not one easy fix to the problems she mentioned and if you think there are, you and I didn't watch the same video. You putting solar panels on your upper-middle-class Seattle home has nothing to do with the entire rework that's going to have to happen across the globe to accommodate this. Suffice it to say, before I go even an inch deeper into this: Unless we do something about China and India's emissions, the entire Western World could literally drop off the map tomorrow and make nary a dent in the bottom line global effect. That seems to be something conveniently ignored. We could commit cultural suicide in the West and go completely dark tomorrow, and nothing would change as far as hitting the climate "event horizon" tipping point. So, there's that. Just remember that unless you decarbonize China and India, nothing you or I do affects any outcomes. Too little way too late. The "exponential" solar growth has been largely subsidized by tax dollars, not market demand. It's also been a colossal cluster-f that has created a slave labor market due to lithium demand and truly offered very little. Even the most fluffed numbers are diresome. Your solution would require *extreme* government intervention to a degree and will require further reach into citizens' already-ailing pockets for a solution that will likely have no meaningful outcome on global temps. (Because again...China and India. I want everything I say here to be viewed from the lens that *nothing* we do matters unless China switches away from coal. They're building entire coal supply railroads to supply the hundreds of new plants they're building yearly...to ironically power their EVs) EV tech is a unidimensional view of environmental harm that ONLY takes the boogeyman of CO2 into account and not the entire Lithium battery pipeline and the actual LIFETIME environmental damage of an EV; The chemicals poured into the earth to refine lithium, the repair, the disposal of lithium, the slave child labor, the problem of there just not *being* enough lithium on the planet for us to go full EV. The smelting and maintenance of the blades, The entire species of migrating birds they're killing, the forests that have to be cleared to erect them. Oh, and solar panels. The toxic chemicals involved in their manufacturing and disposal are only the tip of the iceberg. So you may get some CO2 relief only to poison your water with the toxic manufacturing offshoots of lithium batteries and solar panels. A study I read recently estimates that, in the US, you're saving about 15% CO2 over the entire the life of an EV, when all things are taken into account. (Versus a state of the art economy-minded gasoline vehicle. This study was based in America, where the majority of power is produced by coal. An EV charged by a coal-fired plant is less efficient than many modern gasoline engines. If everyone had the money to kit their houses out with solar panels and buy a $50,000, EV we'd be in business. But until then, I see this new brand of environmentalism as an upper middle-class issue that only the rich have *time* to care about. Couple this with resistance to new nuclear technologies that I see coming from the loudest climate proponents, and I start to realize that many people care a whole lot less about carbon output than they do finding a way to track purchases and tack on new carbon taxes for things we're already paying taxes on. Until the loudest voices in the modern environmental movements take nuclear seriously, I can't take them terribly seriously. I'm on a phone, so unable to really phrase things how I'd like but. The bottom line is there's nothing easy about reworking the entire country's power grid and putting 7p trillions of dollars of new infrastructure to accommodate an electric future. It also ignores so many unintended consequences. The answer right now is nuclear. Maybe in 50 years we will have a viable solution, but that hasn't been invented yet. Current EV tech is pretty much for city-dwellers with minimal commutes who live in climates that don't get too hot or cold. (Because heat destroys a battery's longevity and cold destroys a battery's capacity) It's why most of the people who have such lovely experiences with EVs live on the west coast in temperate climates and drive 30mins or less to work. EV's are an upper middle class luxury right now and until they actually become affordable for the majority, it's going to remain that way.

It is not correct to say that it takes a “few hours” to charge an EV on a road trip. In the US it is easy to drive a Tesla 200+ miles and then charge for less than a half an hour at a Tesla Supercharger. I know this because I’ve been doing it for a decade.

I drive a BEV here in NZ. LFP battery pack(BYD). The only time I ever use fast chargers is when I travel on holiday. Plugging in at night is usually just part of my parking when I get home. (I use a bicycle for trips around town for shopping and recreation). With the conservative way I drive I get 480km on a full charge so range anxiety is non-existent. (20km travel per day usually, with 100km at most) Since I really only use an approximately 1.4kW charger I'm not feeling guilty about overloading the local grid. It never bothers me to just leave the car on charge at home as my car begins the nightly charging cycle during a 3 hours of free charging provided by my power payment plan. My employer also is happy to allow me to charge at work when I'm on the 100km days, it's much cheaper than petrol vouchers. It's all been about planning ahead and charging before I need it, so I don't need to worry about charging. NZ generates at least 40% of it's power using renewables at present, my batteries contain no Ni or Co, and I've had almost no running costs in a year. (wiper fluid and an occasional fancy car-wash) So I'm not feeling very guilty. :)

As I commented last time: the overwhelming number of cars is parked more than 22hrs a day. So you could charge almost all of them all the time with low voltage. Meaning, you wouldn't have significant usage peaks at any time of the day at all. You just need comparably cheap plugs wherever cars are parked. The "alternative charging method in Germany" part is kinda hilarious, because electric trams have been around for 150 years and trains and also buses that are powered this way are not at all new technology.

I think most EVs by far in Norway are charged slowly over night, and quite a few are probably charged slowly at work. In the last video I think she mentioned transformers need to cool down over night in warmer climates. My average electricity consumption has increased by a huge amount since we got an EV so I’m not sure how significant of a problem that will actually be. But even if it is wouldn’t it just be a matter of increasing the size of the container for the transformer, so it has more surface area to cool from? The transformer itself doesn’t need to be bigger

The standard uses case is: Drive to work in the morning, drive home on the afternoon, du things with you car (one needs food and there is something called free time), so the car will be available for charging in the evening. That gives something between 8 and 10 hours of charging. And afaik that is not enough time to fully charge a car with normal voltage. And we would get the usage peak in the night that Sabine is talking about for sure. Also charging something with a powerline while driving is not the same as just using the power. But you are right, it works, but is is very expensive.

Sorry Sabine, some more corrections.. 1. Producing hydrogen gas from electrolysis isn't bad to run on intermittent electricity because the reaction is "slow to ramp" up per se. It's because it becomes uneconomical when the capital cost of electrolysers is (currently) too large to have them "standing by and standing back" most of the time. 2. You stop at 80% most of the time because NMC (nickel, managese, cobolt) Li-on batteries don't like being fully charged & it goes slow at the end - this is not true if you have other battery chemistries like LFP (Lithium iron phosphate) or use an AC charger 11kw or lower. With NMC you should ideally go down only to 20% for the same battery care reasons. 3. Overall maintenance costs for EVs are often lower than ICE cars so long as you take care of the battery - there are far less moving parts that can wear out. At the same time EVs are more expensive to insure for the reasons you explained. One should do an total cost of ownership calculation for it to make any sense of this (fuel/repairs/insurance/interest costs), to see which is "cheaper".

i would very much see that 3 point as well, it is the crux of the issue after all, are we going from a better technology to a worse one or the other way. i would add total cost of ownership over lifetime comparison, which live for longer, which cost more upfront and what other indirect costs are added to own one. sorry for the last point as that rather directly goes against evs, but ive seen quite a lot of comments on it, its nice if you can afford things but its only IF you can afford them and most of the world population can not just jump from poor to rich in a day, it takes tremendous amounts of Work or in other words Energy, energy that must come from somewhere. Sure its nice and "cheap" to charge with your own solar, or heck a mini/residential nuclear power plant, but it will just cost up front in "fuel" rather than step by step in time. in the end i would like us to be realistic, not just have pink coggles on and then get to regret our decisions later in life, i dont really care it were gonna be an EV, ICE or more probably a mix* civilization in the future, i would rather like our efforts to go in the right place and do what they purportedly do than to just appease our feelings, rather shallowly, and make things worse then they are in the long run. *the right technology for the right things

Then another idea is instead of using charging stations along highways, is to have a electrical wire system the vehicle can connect to such as were used by electric trams in cities where a attachment on top of the tram connected to the overhead wires. No charging stations along highways needed at all, and the smaller battery packs only needed for local driving helps to conserve the materials the battery manufacturing requires. Gas stations along highways would be the losers in this scenario but as gasoline is being phased out they would disappear anyway to reappear as something else for land use.

I am glad you revise a video if needed! I drive a Tesla model 3 for 4 years now. And I drive a lot. More than 40.000 km per year. I drive mostly long distances between Holland and the south of France. 4 years ago I had to plan a bit more, to be sure to find superchargers when needed. Now there are almost dubble the amount. So now it’s a breeze. No worries at all. With my previous car I also took a break every 2 or 3 hours just to stay alert and healthy. Now I do the same, at the supercharger. So almost no extra time for me. I would never go back to fuel. Apart from driving cleaner with a BEV, I like how it drives!

Yes. Ditto

I live in an apartment in Los Angeles that I can barely afford. It's a one room studio. I have no parking. My flat is on the same wiring as the apartment building, i.e. utilities included. If I run my air conditioner and the toaster it pops the circuit breaker on main board for the building. All of the building lights and the laundry room go dark. I don't think, even if I had a parking place, that I could charge an EV here. And my work schedule and commute leave me just enough time for 8 hours of sleep and a few hours in the morning for breakfast and chores, so I'm not going to spend that time driving to wait in line at a fast charging point that will then take hours to charge my car. My whole life would then be driving to work, working my shift, driving home, sleeping, waking up, driving to a charging place and waiting, waiting, waiting, then driving to work. I would need a 5 minute charge time, to full, because my commute isn't short. Secondly, there is no room in my budget to even buy another car. I'm driving a 1996 Honda that I had bought for $300. There is no part of my income that can be directed to a new car. I used to have a short commute until my workplace moved. I don't fly anywhere, I live in 300 sq ft of space, while others live in lavish 11,000 sq ft homes, jet set to Europe multiple times per year, consume on a much grander scale than I can even imagine, but oh, they drive Teslas and are saving the world.

Thanks, Sabine for saying very important things that aren't heard anywhere else. I heard "subsidies" in this video many times, and sadly this is true. However, we observe that governments deal with it in two ways: 1. They put additional requirements and costs on energy distributors and producers (ETS costs and others), those regulations increase the cost of producing energy which is the reason why prices of energy in the EU are one of the highest in the world and still rising. One of the craziest regulations was to force energy distributors to buy power generated privately from solar or wind generators even if that power cannot be sold, or can only be sold at a fraction of what that private producer gets for it. This also needs to be financed from higher bills for homeowners. It also makes the energy market chaotic, green power is not produced in places that need that power, it is wasted and we pay for that waste. 2. They do indeed make subsidies, which need to be financed, from taxes of course, which makes the EU a place with the sharpest rising taxes in the last years, and more are in the way.

Since you asked... We bought our first Tesla in 2019, only maintenance was cabin filter and tires. Practically no brake wear as we use regenerative braking. No coolant/Oil to worry about. No engine to turn on for heating and cooling. No range anxiety, 100% reliable superchargers. We have one home charger in the garage, plenty for our family fleet of, now 4, Teslas.

GREAT point, which is almost always overlooked in discussions of public policy. A corollary is that people won't willingly live in energy-efficient areas (i.e., dense cities) if those are not safe, pleasant, and affordable. Personally, I was raised in a large city and prefer it in many ways. I would much rather walk everywhere than drive everywhere. However, I live in a small suburban city because the large cities near me are unsafe, unpleasant, and unaffordable. I am sorry to say this, but the wealthier neighbors I have don't rob my house, steal my stuff, shoplift, carjack, join gangs, filth things up, ruin the schools, and overburden the safety net. I have to drive to everything, which I hate, but it's a great defense against undesirables. (BTW, this isn't closet racism. My neighborhood is very multi-racial. They're just not criminals and deadbeats. And yes, I recognize how classist that is. But when urban governments don't protect the productive people, they protect themselves by moving away. And that's a huge driver for carbon emissions, which liberals refuse to even discuss. And, to be politically balanced, part of the reason for large city failures has been off-shoring caused by not charging for carbon emissions and pollution by means of taxes and import duties, which conservatives refuse to even discuss.)

Effective? Yes, there are way more effective ways to remodel our cities to allow for all kind of EVs (trams, trains, subway, bikes, scooters, bicycles) AND walkable ones at the cost of people's sanity, as you'd have to squeeze everyone together if you were to make everything walkable, you'd have to stack people on top of each other in smaller housing and tall towers. Now, it's not realistic at all, i'd say it's even more unrealistic than anarchism and/or communism. We could make new cities based around that concept, but who would even move there in the first place? When the reason they've moved to the big cities is because everyone is there and everything they need is already there, despite how uncomfy it may be, so you'd have to forcefully evict and rehome everyone on the new comfortable and efficient city. Changing cities to accomodate for better transportation and transit so people can use efficient EVs, public transport and still have all the vehicles needed to restock stores and deliver big objects or big amounts of materials to people's houses is outright impossible from an economic point of view. You would have to cut many roads to install trams, have lanes for public transports and you'd still need to have accessible roads for trucks everywhere to restock stores or to move furniture and other big stuff around.

The Sahara is also immense. Also, there is that concept of solar-wind chimneys that take advantage of the Mountains height to embed in them chimneyes that can be as high as one kilometer, the base-to-top differential in temperature and pressure can be used to generate electricity with turbines.

Standard single phase residential voltage in the USA is 240v (effective average absolute potential) 60hz. The way we reference it to the ground it alternates from -170v to +170v (peaks of sine wave), and so low power recepticals can operate at half potential, or 120v(average), by using either of the two legs with a ground conected neutral conductor. But in short all homes in the USA have 240v power, very old homes with non-electric heat having 100amp and most newer homes 200amp service. (150 is common also in a few regions, and very large homes, those with a substantial workshop(welding and such) or sharing a connection with a commercial business will have 400amp) A few appartment buildings use 208v/120v but that is a 3phase which is higher total power and they inherently have easy access to any other 3phase voltage, wye or delta up to ~13kV (the common streetside voltage and occationally used directly in heavy industry. Trunk distribution is 115kV up to 1000kV). In practice 480v/277v is very common, 600v in industrial settings and 4.2kV for special purposes.

@@KevinLyda yes, that makes sense. it might be easier for the employer to provide the infrastructure necessary (you've one single point of construction required) than everyone doing something at home. it might also be easier to observe that no one abuses or pranks them charging vehicles (like it's easy to see with street side parking and charging during nighttimes.) this could either be tax incentivised or an outright legal requirements for companies above a certain size to offer. ideally for free of charge so that more people feel to urge to capitalize from this fact. yes, sounds doable. 👍 (especially when electricity is free at work, people won't charge up their vehicle unreasonably during night. just enough to make it to work.)

In Australia, the biggest problem with EV uptake is cost. And we will very soon have EVs which cost the same or less than smelly cars. Many residences in Australia are detached houses with garages and 240v systems that can support a Type 2 charger charging at 7 kW per hour. More and more Australian houses are installing rooftop solar which can be used for daytime charging. EVs use less domestic energy than old electric hot water services and replacing old hot water services with heat pump systems would just about offset EVs. (The big electricity drain is air conditioning.)

Indeed. Here in Germany, electricity delivered through the public grid is actually going down, despite electric cars and electric heat pumps becoming more and more common. Because ... well, rooftop solar. Some supermarkets have started roofing their parking lots with solar panels, so customers keep their cars out of the sun and can charge a bit for free while shopping. Not sure why Sabine found only sources expecting a need for big and expensive grid updates.

If your commute is less than 20% of your EV's range, you can ride all 5 workdays from one charge and refill on the weekend. Also, kind employers have solar at their office/factory and allow to charge from that. If all this fails, one can always fall back to charging from the grid, so no fear of stranding with empty batteries somewhere.

@@jemima_brown You make good points. Home batteries at the moment are too small and expensive for EV charging at night. However, many people now work from home and even one hour of charging on a 7 kW charger will put about 40 km of range in an EV. Even if the family EV is not at home for charging during the day, solar can supply power for the house during the day and the EV can be charged at night; this can take much of the peak demand off the grid and remove the necessity for grid upgrades. Many businesses have large roof areas which could support panels for daytime charging of employee cars as an incentive for employees to work in the office.

Comparing the cost to replace the battery with the cost to replace the gas tank makes sense from a functional standpoint (both store energy), but not really from a cost of ownership standpoint. In an ICE vehicle, most of the major repair costs related to the drivetrain are due to engine malfunction. In an EV, the largest potential cost is due to the battery failure. Battery replacement for most EVs will still tend to be more expensive, but not by nearly so great a margin. The other factor to consider is how common battery failures are compared to major engine failures. I don't know the answer to that one.

I live in Scotland. Until April 2023 it was free to charge your car, in early 2023 getting a charger was becoming more and kore difficult as more and more people bought electric cars. As of April 2023 you are now charged either 33p pkw or 50p pkw, depending on the charger. Now all the charger stations are empty as it is cheaper to charge at home. If you have a jome charger installed for free by your power company, it will cost you 12p pkw. Far cheaper and no hunting around for a charging point. Clean air and fast than most petrol cars.

This was great to see - thank you for responding to the comments. Some of the issues you brought up had a much better balance this time. Please take a look at RethinkX and respond to their analysis of this problem of economic cost and benefits of this transition. A few points I'd like to make: 1) Electric vehicle costs are declining quickly and not increasing. As an example, Jim Farley's Ford has cut the price of the F150 pickup by roughly $10k US in the past week. 2) Maintenance costs for electric vehicles are significantly lower than internal combustion vehicles. This is proven across manufacturers and includes collision repair. 3) If you include oil and gas production as mineral extraction (which you should), electric vehicles require significantly less minerals. (Some simple math => 150,000 miles at 25 miles per gallon times 6 pounds per gallon equals 16.4 tons of fuel - none of which can be recycled).

I was born brain damaged and I'm now blind. I live in London and obviously have never been medically allowed to drive a car. I have relied on public transport and my own two feet, traveling the 10 miles to school on my own via train since the age of 8. I would severely severely struggle in the countryside but London is very connected with public transport albeit not perfect but definitely good enough. I do use taxis when my health is poor or its a really tricky journey to make (like going to Guys & St Thomas's Hospital absolutely need a taxi for that). But I live independently and nobody within 75 miles that I know can drive a car. So I'm pretty much car free except for the occasional taxis. London is great for being able to go car free although there are obviously some limitations.

Reasons why the development of super-conductors is so important: reducing the impact on the electrical grid, AND facilitating the manufacture of more efficient powerful magnets to build tokamak fusion reactors. To increase the capacity of the electrical grids, is going to require a lot of copper and aluminum unless we can acquire super conductors with Tc’s greater than 100C.

Thanks Sabine, you do an amazing job with your videos. I ordered a battery EV car last week. Tested it a few weeks ago and it was some really cool experience, and that's an understatement. Why now? Well, because the technology reached the point to be practical _in the place where I live in_, and that's a very important distinction. The car has a 77kWh battery, that gives you around 550km of range. The island where I live in (Gran Canaria) is perfect for this kind of range, in fact with a fully charged battery I could drive round-trips around the whole island 3 times and still have a quite a bit of battery left, so the range anxiety depends a lot on the circumstances of every individual driver and the place where the car will be used. I will have a 7.2kW charging station at home, so the battery will be full every morning easily, and I don't think I will have to ever go to a public charging station at all. So at the end for the question "Are EV cars practical?" the answer is "Depends on where you live". At some places, like where I live, it is already, by far. But, for some other bigger places where you may have to drive for hundreds of kilometers in a single day, the situation can be more complicated, and depends too much on charger infrastructure.

In New Zealand, BP is a significant player, but not the biggest, in providing charge points at each petrol station (or working on it anyway). I stop there for a quick get me home charge in my leaf sometimes. They charge 3x the market rate per unit or kWh, but that's good... There are free chargers around, but everyone queues for those. Not for the pay stations. Remember, you only have to recharge what you used. If you only drive 40km in a day, that's 3 hours on a slow home charge outlet, without any special wiring.

Congratulations on your episode on electric cars. A couple of points from someone who has driven a Kia Soul EV for 3 years. They are fantastic to drive. Far nicer and easier than a I/C car. If you have off street parking(60% in U.K.) you can start every day with a ‘full tank’. Overnight charging is far cheaper on low rate tariff. Cost of ownership is way lower. In the first two years we didn’t use a commercial charger once. With a range of 260/300 miles, depending on ambient temperature, it wasn’t necessary with our sort of driving. Normally you charge to 80% for good battery life but if you have a long journey you set to 100%. The battery on our car does not seem to have deteriorated in the 3 years. However, I would not have one if I was driving 500/800 miles a week and be cautious if I did not have off street parking. However the charging infrastructure in UK is improving rapidly and we have done 1000 mile round trips since the pandemic with relative ease. Watch out for the many 7kw chargers though. A service station overnight is not fun! Remember if you are charging at home the odd 40 mins in a service area still means you are spending less time ‘filling up’ than an I/C car. Obviously I am looking at this from the user angle and understand the implications for updating the power grid etc. No more awful I/C stop/start systems driving me mad and no worry during petrol/diesel shortages. Oh, and servicing is minimal!

Gas shortages don't occur often enough to be an argument against an IC car and finally, the maintenance is mininal on all new cars - IC or electric. After a few years (or enough kilometers) the maintenance will be significantly more expensive on your electric car then on a comparable IC one.

The minimal servicing is nice, in theory as long as the servicing is opened up to all mechanics.

Thanks for the video.

I think energy efficiency is the Key to the EV transition, which is one of the motivations for buying the I3. More efficient vehicles would surmount a lot of the problems you correctly raise.

There is a hydrogen version of this where hydrogen is stored chemically bonded to some substance (can't recall what of course) in a canister that you swap out instead of pumping hydrogen into your tank, but with similar output as a pressurized tank.

What matters are efficiency factors and the H2 people are quickly catching up.

It is important to note that in the United States, the vast majority of homes have 240V "available", along with 120V. Exceptions would include very small apartments and some very old homes. The issue is that only a few large, power-hungry appliances in a typical American home use 240V circuits, so there are rarely 240V receptacles in a garage, for example, unless they have been installed for EV charging, or a large welder. Many newer American homes have 200-Amp service, so at 240V, that's 48 Kilowatts, assuming a 200A main breaker that can handle 100% load continuously (I don't know if main breakers in US breaker panels are typically rated for 100% load, but in almost all cases, the individual circuit breakers are rated to carry only 80% of their marked capacity).

@DarronBirgenheier

9 ай бұрын

Almost all circuits in an American home that have receptacles that you can see and use are 120V, almost always with either a 15 or 20 Amp rating. It is possible here to have 120V circuits at 30A or more, even with receptacles made for these ratings, but I've NEVER seen one in the US, despite being a bit of an electrical nerd. There are people here now installing 240-Volt, 100-Amp circuits to their garages, usually to power an EV charger at no more than 80 Amps, due to the 80% breaker rating thing. I believe the new Ford Lightning electric pickup truck can use the full capability of such a circuit to charge at home.

A few items to consider. The energy used to generate U.S. electricity is currently about the same order of magnitude as the total energy from gasoline and diesel for transportation. So it will be a huge challenge if we are to phase out generation from natural gas and coal and replace the electricity with generation from solar panels and wind turbines while steadily doubling the demand caused by converting to EV's. You did a good job highlighting the problems with infrastructure for charging and transmission. However, you could add more for sources of electricity. Current plans are to depend on solar panels (mostly from China) and wind turbines. However, solar panels only provide an average of 25% of rated capacity and wind turbines 35% compared to 94% for nuclear. The problem with solar panels is they don't work at night and work poorly in the morning, evening and when it is cloudy. Average demand for U.S. electricity is highest in August, but U.S. average generation from wind turbines is not only lowest in August, it is frequently lowest at mid day when electricity demand is highest. You mentioned that most people will likely charge their EV batteries at night. But if say 25-30% of our electricity comes from solar panels, that won't work. We might use wind turbines, but we would probably need 5-10 times the number calculated to meet average demands to account for the daily variability in the wind and solar panels only being effective about 6-8 hours per day. We might consider large banks of batteries. Iron flow batteries are a promising technology, but energy density is too low to be cost effective for cars. Iron is not toxic and does not burn like lithium does when exposed to water and iron is very abundant. But then there is the same question as we have for EV's about when to charge them. If the batteries are designed to be used at night when solar is not available, when do we charge the batteries? During the day won't work because demand is highest then unless we have a lot more solar panels, but then there is the liability on cloudy days. I built an economic model to represent 3 days of electricity supply and demand in 4 hour time slices. The only way I got utility scale batteries to be useful is to charge them during the day using electricity from the coal and natural gas plants that are supposed to be shut down. Nuclear should still be considered a clear option especially the Integral Fast Reactor designed by Argonne National Laboratory. They built a very effective one, but the program was cancelled for political reasons by President Clinton based on a strong push from John Kerry (our climate czar).

I just listened to a KZread presentation from Peter Zeihn, discussing deep geothermal heat as a source for generating electricity. This source takes advantage of developments from shale oil technology. He pointed out that the footprint for shale oil sites is smaller and a new shale site can be in production in just a few weeks and costs less. In his presentation he reports that a pilot geothermal installation exists to prove the viability of the source. The advantage of deep geothermal heat is that this source is not subject to time of day or the weather. Therefore It can even be considered as a base load generator. If adopted country wide, depending on how it is implemented the need for transmission grid updates might be reduced. Every state would want one or more. One problem is the possibility of a paradigm shift from thinking big. Suppose the generator could fit into the area of a substation. (even if it could be used for very large generator equipment). With smaller generators, the impact of a network generator failure would be reduced. It would increase redundancy Deep heat is everywhere, and abundant. Would companies accept a smaller but more numerous generator environment? Probably not, just as legacy auto makers rejected single casting of the car body, until Tesla proved its power, and showed it possible. The human mind set beliefs are hard to change. It is easier to bring up objections because that is the way it has always been done.

I drive an electric vehicle already. It is a hyundai kona with 300 Km range. We use the car for 22.000 km a year. We live in a small town on the countryside of northern Germany. A lot of people go electric here. I think there have been misconceptions of BEVs from the start. They thought of them as small vehicles for the city. But there is no charging infrastructure. Here, on the countryside almoust everyone has a house and a parking space next to it. They all charge at home. Furthermore: almoust every household here has two or more cars, but no one needs them both to have 700 km range. So they often first change one of their cars to electric. Our experience is: We rarely need a car with more than 300 km of range. We don´t care if we had to wait 30 minutes on a longe trip to recharge. On the other side we save a lot of money and time during normal working weeks with charging at home. We don´t miss the gas station. Also the comfort in an BEV is much higher, the music sounds better without engine noises.

I've been driving my first electric car (Kia eNiro) since just over 2 years. Wouldn't go back to an ICE. Solar charging at home 80% for local/regional driving, 20% charging on the road for long drives. The infrastructure is getting better, and we are getting better at dealing with any issues. I keep on trying to promote adoption amongst friends, with some success. Living near Munich.

Hi Sabine, Love your direct presentation style and balanced presentation of data. The origin impetus for us buying our first EV, the Leaf, was to allow us to better benefit from the electricity our PV was generating rather than exporting it to the grid at a much lower rate than our imported electricity costs. We are presently upsizing our PV to allow us to satisfy the higher AC charging rate our Polestar will accept. My point is that many EV owners either do, or aspire to, charging their vehicles from their own solar generation. Apart from the cost benefits there is also the advantage of knowing that their EV is using fully renewable fossil fuel free electricity, AKA running your EV on sunshine. Also in regard to the demand on grid infrastructure that you identify the charging of EVs from generation in the immediate vicinity (home or workplace) mitigates this grid demand. In addition the adoption of V2G and V2H functionality will further buffer both peak grid demand and peak daytime generation from PV which it is used as the charging source. Much has been said by futurists such as Tony Seba in this regard and on the changing ways we will source energy and the uses we will put it to in the coming decades. EVs are just part of a much wider network that will change hugely in the coming years.

Contemporary design is focussing on prestige cars requiring more power long range capability. A different mind set is required. It's not just about transportation.

Instead of setting legislative goals for individual citizens, governments could be setting legislative goals for producers of energy, but that would make too much sense.

I drive a plug-in hybrid car and find that it is perfect for a small city. The approximate 35 km electric range from charging at home takes me anywhere in the city the next day. I rarely need to fill with gas, but never have "range anxiety". As a bonus, I love the smoothness, quietness, and strong torque of the electric motor.

In Norway, 8 of 10 new personal vehicles sold are in 2023 electric and soon 24% of the entire vehicle stock is already electric. It is about four times more expensive to drive a diesel or pertrol car than an EV in that country when considering just the fuel costs. Most people of course charge their cars at home and super-chargers are mostly used during long-distance driving. Hence, the problem with lack of charging infrastructure is somewhat overstated. Smart grid solutions will enable electricity production that is vastly more efficient than it is today. Even in countries where the energy mix is mostly made up of brown coal, it is a lot easier to reduce CO2 emissions from power stations than it is from individual vehicles. The "problem" with cobalt in battery production is very soon a thing of the past. With respect to the cost of fuel it is easy to forget that a finite resource only can get more expensive, while renewable sources can only become cheaper over time. The cost of battery production will also be significantly reduced over time with evolving battery technologies and capacity. Even if 90% of all new vehicles in Europe would be electric by 2030 it will still likely take a hundred years until we stop producing oil and gas. One should also not forget the subsidies that have been and still are paid each year to the oil industry when comparing costs.

AS I mentioned on the first iteration: using my EV for 2,5 months now and had zero issues. I was always able to find charging stations fpr a reasonable price. I also did a trip over 1800km from southern Germany to Dresden, through Tzech Republic and back. Really nice driving. Only thing I have adjusted is my speed of travel as i ever go over 120km/h and most of the time drive 110km/h. Range anxiety has vanished with this trip too as it is nearly always possible to find a opportunity to recharge as the electrical grid is nearly everywhere.

Sabine, you are wrong about hybrids: they recover a significant amount of energy from braking. Braking accounts for most of the energy loss of a car. The efficiency of regenerative braking can be high, often around 70% to 80% or even higher in some cases. This means that about 70% to 80% of the kinetic energy of the vehicle during braking can be converted back into electrical energy and stored in the battery. Without friction and with say 25% energy loss from regenerative braking; you'd be recovering 75% of the energy. The other thing is the combination of an electric motor and an internal combustion engine in a hybrid car results in lower maintenance costs and less wear on the components. The electric engine needs much less maintenance than gasoline. Also, having a gasoline engine is a huge plus during power failures!

Sabine, your thoughts on using solar/wind as a power source for the additional load? Love your work!!! ❤

The fact that I didn't notice any mistakes in the first video serves as a reminder not to blindly trust _all_ the brilliant and funny theoretical physicists we're subscribed to... 😎

It was mostly outdated information. Which is kinda understandable. If you find numbers in astrophysics from 5 years ago, they don't suddenly be wrong, if you find numbers regarding EVs from 5 years ago, those are garbage now.

Funny, more than once during this video I said to myself "but what about..." then you promptly talked about the what. Nicely done. I would love to hear a deeper dive on recycling of the various types of battery packs. It seems there are only two types of recycling videos, terrible recycling or awesome recycling. The awesome recycling videos tend to have more real data than opinions. We've had a Model Y long range for two years and we love it. I find it cumbersome and awkward when I am required to drive a gas car now. The lag in throttle response and having to switch to the brake pedal every time you stop or slow down is annoying. I also like the 8 year, 125,000 mile drivetrain and battery pack warranty.

Yes a deeper dive would be nice. Until then, the short version is that several researches (including one done by AU Govt) has shown that recycling 90% of batteries is totally feasible and economical. There will be some difficulties, but it can be done. One of the current difficulties simply is the demand for that at the moment. There are a few companies around that are already completely recycling batteries, but those are very few and far between. Again simply because there is not a big demand for needing more at the moment. And there likely will not be a strong demand for that quite some time to come. As batteries, especially those for vehicles and generally some sort of lithium base, will have a second life purpose elsewhere for a very long time. For instance a battery bank for a vehicle can easily last well over a decade as its life expectancy. But that life expectancy is going to be about 70% SoC. So those will unlikely be recycled as you will likely be able to sell it for a second purpose use for better price than recycling company can make. And that battery bank will last another very long time. You are easily talking about decades before it needs recycling. There will be a demand down the road in the future, in like say 30 years or longer. Batteries banks will more than likely in most cases outlast the vehicle before it even reaches its life expectancy, and then see a second life elsewhere, although there will always be exceptions of course.

A small correction In Greece pure electric vehicles (BEVs) constitute 3-5% (instead of 1% stated in the video) of new passenger car sales monthly and this has been consistent since mid 2022

The true solution is cheap, clean and reliable public transport systems for both commuters and freight.

Apparently 45% of Americans have no access to public transport. Changing that might be less than the trillions needed to upgrade the electrical system but it is unlikely to happen, especially since devotion to cars is entrenched as it is.

I saw some chargers at a UK motorway service station recently that were out of action because they could not get a connection to the grid. It's mind boggling to think of every car in a motorway service area connected to a 100 kW charger. How much power will that require?

Lots, but at least a lot of the Tesla supercharger stations have megapack batteries installed which charge up when power is cheap. A lot also have solar roofs connected to the batteries.

@@user-gg4is6db4u Large batteries and solar power will help but an expansion of the grid will also be necessary. A typical solar panel might produce 200 W per m2 so to power one 100 kW charger you would need 500 m2 of panels or 5400 ft2. You'll need even more to keep one charging station going 24 hours/day.

Invariably the hold up for connections is not due to technical challenges. Politics, planning, arguments over competition rights etc etc. Largest site in USA has 120 bays. Presently Tesla in Europe are maxing at 40 bays. By the time you get above 16 or so bays the turnover is very swift so I would think that 40 could be an optimum for large motorway service areas in the future.

@@AlanRPaine I think the worry about the grid is somewhat overstated - Gigabatteries are being installed in many locations, virtual power stations mean that communities with domestic batteries (like Powerwall) can feed back into the grid when needed, and accept excess power. I believe the rise of EVs and sustainable energy will help stabilise and protect the grid.

I run a phev. I have a long commute but even so it manages 65 to 80km per litter of fuel. Cold weather reduced efficiency. PHEV make the most sense at present whilst we build grid and charging capacity. My experience is that a prius phv uses 1/10th of the fuel used for a smaller Mazda demio. Where I live most people would not commute as far as I do and the grid is 90% renewable. It seems strange that we don't extoll the phv as the ideal right now.

Great video and analysis of the problems with the role out of electric vehicles. Would love to also see a spotlight done on the lack of technology in regards to recycling electric cars once their lifespan is over and a comparative analysis of electric car lifespan to internal combustion car lifespan.
