There were several comments saying that I did not take into account the CO2 released in the pumping, refining and transportation of crude oil. While indeed, these processes emit CO2, we should remember that at least 60% of the electricity produced world wide uses fossil fuels, including coal, natural gas, petroleum, and other gases. So in order to be fair, the CO2 emitted in the extracting, refining and transportation of these fossil fuels must also be taken account for electricity generation. In my view this aspect is somewhat of a wash for both gasoline-powered and electric cars. And even without taking this into account, we can see that the conclusions of this video would still be valid, from the most conservative viewpoint.

On the other side another minor inefficiency of the transport of electricity via the grid and other supporting infrastructure, with the projected necessary expansions (in case EVs quickly ramp up in numbers) and their associated emissions also worth a mention. This gets complicated fast because one can argue the extensions of the grid becomes important anyway, and just how much is due to ev adoption could bee debated. An other interesting question is how EVs lower direct air pollution in the cities air which can depend on factors like where, and what kind of power plant provides the charging. That being said it is fair and excellent video about how we should look at these problems from an objective point of view. One more thing to consider though, mass transport via electric trains are even more efficient.

Oil products including diesel is used extensively to produce electricity, so it is not always a useful figure to use. In the US, natural gas is used extensively to produce electricity.

@KDawg5000

@@ArvinAsh My point was, when these comparisons are made, *everything* should be taken into account. Otherwise how do we have a true contrast? The electricity used to refine one gallon of gasoline will propel an EV further than that gallon of gasoline will a gas car. So the gas car is actually creating CO2 from burning the fuel, and also from the electricity the refining process requires, and several other sources of CO2 to maintain the gasoline supply. Petroleum is used very little to produce electricity, yet it is used exclusively to propel gas cars (as well as for oil changes).

Of course, one must also take into account the fact that as more and more EV’s come into use, more and more charging stations must also be manufactured, which will also cause more CO2 to be released. Secondly, the current (no pun) electrical grid in the US, and I would think in other countries cannot handle the increased demand for power if the majority of vehicles become EV’s. This will also need to be replaced (i. e. manufactured) as well, releasing more greenhouse gases. The EV solution cannot take place overnight. It will take years, if not decades.

Aside from greenhouse gases, not being energy dependent upon countries who aren't very friendly is a huge bonus. We spend a trillion dollars +/- per year on defense to protect ourselves from countries building militaries with fossil fuel money or being forced to deal with those with horrific human rights records.

Even the people making the EV’s are shaking their heads in disbelief as to why Politicians are pretending they are green. They should of kept with cleaner emissions from ICE cars.

I personally think that the best reason to buy battery-electric cars is simply that _they are just better cars_ ! They’re more responsive, quieter, faster-accelerating, and smoother in every sense. They also require a lot less maintenance. If you can charge at home, they’re more convenient to fuel up: 5 seconds to plug in at night (once you get it all set up), and five seconds to unplug in the morning! Yes, road trips are more involved, but most people only take a 3-4 road trips per year. Most EVs’ GOS navigation systems include navigation through DC fast-charging stations, which are increasingly common. For most people, they’re also cheaper per mile, although that varies a lot by locale. They keep smoke out of residential and pedestrian -intensive areas.

Great topic and video! 5:14 - It’s worth pointing out that this 75-85% number includes losses charging and discharging the battery. Just the motors themselves are on the order of 90% efficient. 6:45 - Actually, although lithium ions are what transfer charge between the electrodes, lithium batteries are only around 7-8% lithium. Other elements, like cobalt and nickel, are bigger concerns. Also, the most common lithium-mining method is not an extremely energy-intensive process, but it is a very water-consuming process. It’s also worth pointing out that most new battery-manufacturing plants are designed to run on renewable energy, so that part of the process is less carbon-intensive. 9:25 - Indeed! Most people don’t fully grasp just how inefficient a space- and weight-constrained internal-combustion engine is, especially when rarely allowed to run under optimum RPM and temperature conditions in general. That’s one of several ways that hybrid vehicles reduce fuel consumption, BTW: They endeavor to shut off the engine entirely, except when it can operate at close to optimum conditions.

I agree and my view is If you scale that one percent ev's worldwide to 50 or 75 percent or so, all the grids in the world need to be fortified to deliver the power needed to charge al those ev's as fast as possible. This will take A LOT of copper for example. Powerplants need to be built (hopefully nuclear) to supply for the increased demand of raw electricity and the people who build all that infrastructure need to be fed. Extra factories for billions of batteries need to be built and new mines need to opened for the resources for those batteries and infrastructure changes. Charging stations need to be built everywhere and in theory you would need more of them because it takes longer for an electric car to fill and you drive less km with a full battery compared to a full tank. And i probably missed some more yet unknown issues we need to take into account. In my personal opinion the EV remains a technical utopia if we do not manage to control the total energy balance and conversion efficiency. The energy source/storage with the highest conversion efficiency (as you may know, energy is always converted, never 'won' or 'lost') and the highest energy density (joules/kg) will always win in the long run, we only need to find and combine the best ones, like nuclear ( 1 kg of uranium replaces about 1000 kg of coal i think) for electricity generation.

@@fredhawken1112 All good points, and for reasons like those I don't think the future of electricity management will look anything like the current system does now. When petrol took over from the horse and buggy, there were alot of projections for future needs based on what horse and buggy travel required. Same stuff is happening now. Safe to guess however that a complete replacement of petrol vehicles won't happen soon. Petrol and electric vehicles both thrive economically under different conditions, so alot of people will probably end up with one of each. Gas or diesel as a backup/for long trips, and electric for around town use. Further speculation might suggest solar panels will become a standard feature on electric vehicles offsetting several miles of demand per day(the ultra efficient three-wheeler in California is rated at 20 miles/day from onboard solar for example). Solar Panel technology is rapidly improving as well, it's getting cheaper and simpler to tie solar power harvesting into homes. The benefits will only become more notable and economical as electricity prices go up(seems a safe bet they will). In many rural locations going offgrid vs connecting to utilities for a new home build is already a cheaper option, and adding in a few panels to support a car(batteries are the expensive part of solar implementation) is a negligible expense. Especially with a petrol backup, an electric car can double as a booster to offgrid energy stability(when it rains a week straight for example.) Electric cars are a much younger technology than ICE vehicles. There's alot of growing room. Different locations will be better suited for different ratios of each as well(imagine living in a place where the average temperature is negative with anything BUT an ICE vehicle, not happening). In conclusion I'd offer that electric vehicle adoption won't look like we might straight-forwardly project it will, ICE vehicles will remain a mainstream choice of travel working synergistically with electric vehicles, and the rapid exploration and improvement of complimentary electrical systems will have a multiplicative effect on the speed at which these systems get adopted.

Small hybrid cars with relatively small batteries could be a good option overall, most journeys are quite short.

It’s a bit complicated. It depends on the car (weight and battery size), the country (for its national source of electricity - France is all nuclear and renewable for example while Poland is mostly coal) and the drivers use case. I drive a relatively small EV and do about 70 miles per day. It works perfectly for me and beats the diesel I had before ( which I loved! ). I ‘m happy I made the switch, but I had to do a lot of homework and cost analysis to see if it was the right choice for me. At work, I got the job of assessing our field teams vehicle use, who often drive 3000 miles a month and over 300 miles per day. Factoring all things the company was interested in (CO2, practicality, cost, etc), the answer was to stay with diesel for at least another two years. Changes are always coming and I’ll be rerunning the analysis every year. One day, electric will probably win, but for their use, not yet. We live in a hybrid (sorry!) time for cars. The right answer for each person right now could be petrol, diesel, hybrid or full electric. As I said at the start, it’s complicated!😊

Effective public transport is not a thing in the UK unfortunately unless you in London.

A nice video! Still I have many concerns. Can an ev battery be regenerated? At what cost? What about disposing it? What about environmental issues and how much impact would it have if 90% of vehicles would be EV? How much CO2 does disposing battery emit comparing to scrapping a combustion engine car? What is an average lifespan of both solutions? What about economic costs? Most people can't afford EV at the moment anyway. The biggest problem I have this transition into ev is strongly influenced by politicians and the history teaches us it ends very badly most of the time. This also creates misallocation of resources in economy and waste of energy itself.

its an alright video, he left out a number of factors, such as what about hybrid cars, what about having enough resources to even replace all of those vehicles, what about since EVs tend to be heavier, the wear and tear they cause on roads, what about other solutions such as an increase in public transport as an option. what about making cities more bike and ebike friendly. making things walkable. I feel like changing every vehicle to an EV is an extreme scenario, that should be considered as a last result. as we could easily do other things with the infrastructure that we already have available to significantly reduce out pollution output to reasonable levels. For me I would honestly love to take the bus everywhere, however, in the US buses tend to not have enough routes, or a large bus station that you can go to. then when it comes to greyhounds and longer bus transit, it is less expensive to drive a car than it is to take a bus. With that price the time of travel tends to be 4 to 5 times as long, making a 2 hour trip into a 8 hour endeavor. Making public transport more of an option, or just making sidewalks so that it isn't dangerous to walk outside is a much much cheaper and more effective way to reduce emissions than trying to replace 10s of millions of cars. I wish you went into more detail about other alternatives than just 'oh an ev is better that's what you should look to get in the future'. cause again road damage such as potholes are caused by heavy vehicles traveling across them, so increasing the average weight of a car by several tons will significantly increase road damage causing entire roads to need to be replaced much more often then the current 30ish years. with that I believe hybrid cars are an excellent remedy for this issues, as some hybrids are bordering on 50 miles a gallon, and their efficiency has only been increasing. oh and how could I forget the increase to the electric grid due to so many more people owning evs that's a whole another issue. sorry for the rant, i would just rather not have to drive at all, heck for the summer i was driving 17 miles round trip per day to get to work. I just used an ebike, which has much less impact on the environment.

Cars are not the problem. Public transportation is.

Transportation accounts for 29% of all greenhouse gas emissions. That's all transportation, including air travel, ships, rail, trucks, and cars. Even if everyone on earth switched to an EV right now (assuming the charging infrastructure was in place, and all the electricity came from "green" sources, and ignoring the resources needed to manufacture billions of EVs) the effect would be only on a portion of that 29% of greenhouse gasses. The push for EVs is a distraction. EVs aren't the answer.

One thing is overlooked here. As demand for EVs reaches parity with IC vehicles, the demand for electricity will sky rocket and unless there's a giant shift towards cleaner energy production then it's moot. There's a whole host of other problems not related to emissions like infrastructure for charging, poor range and reduce performance in colder climates where a higher demand is placed on the battery from tempreture and additional power draw for ancillaries.

From a futuristic point of view, there is no doubt that EV come out victorious. Electricity is much more versatile after its been produced. Imagine the emissions released just from transporting the fuel to the petrol/gas stations.

Excellent presentation of a relatively obscure topic for most of the viewers. At personal level there is another problem.

Automobiles are, regardless of their motive power type, a much less efficient form of transport than almost any form of mass transit. They expend a lot of energy just to move the vehicle, which can only ever carry a handful of passengers and frequently carries just the driver, and they occupy a relatively large physical volume of space on the road. A larger mass transit vehicle -- like a bus -- uses less energy *and* a smaller volume of road occupied per passenger per mile/km. On top of that, rubber-wheeled vehicles on asphalt roads are inherently much less energy-efficient than metal-wheel vehicles on metal rails: the former has a lot more rolling resistance just to move. You can also chain railed vehicles together much more easily, amplifying the energy expended per passenger per mile/km advantage even further. All these advantages and disadvantages add up and multiply one another. At a certain scale, and depending on the power source used to charge the EVs, a fleet of cutting-edge EVs becomes more polluting than a 100-year-old coal-fired steam locomotive pulling enough passenger cars to move the same quantity of people over the same distance in the same time. EVs alone aren't going to solve climate change. We need mass public transit, and we need it on an epic scale in a hurry. TL;DR: car bad train good

I live in Brazil and have used ethanol from sugar cane (100% renewable and not contributing to global warming) as fuel since 1986 (when I started driving). Most cars are “flex”, meaning you can choose between ethanol and gasoline. Worth mentioning that gasoline in Brazil contains 22% ethanol. A portion of Brazil is already “carbon free” concerning fossils fuels and switching to EVs will not help on that. I also produce my own eletricity (500-800 kwh/month on solar panels) and would like to to have an EV to save on fuel. However, we are far from a positive business case here… an EV cost 3x (or more) than a flex car and it doesn’t pay off during the most of its lifecycle. Once it drops to within 20-30% of a flex vehicle, I will consider it

In many cases your personal demand for a vehicle is not under your control at all and it is in fact dictated by the place that you live

An overlooked drawback of EV's and air quality is that a significant portion of airborne particulates comes from the rubber dust created from the friction of the tires. EV's emit just as much as ICE vehicles in that regard.

You should consider the costs of Oil and Co2 for production, extraction, car consumption, and oil leaks into Nature into this study

Saying that EVs are responsible for the emissions of power generation is a misdirection: the transition to EVs doesn't solve all greenhouse gas emission problems, but it removes a bottleneck that currently exists in transportation. EVs are only part of the equation, but they're a necessary part!

The "good" folk at the WEF can pay for any marketing stunt...

I drive a PHEV and think there are a few things worth considering that you didn’t cover in this video: 1. The location that the CO2 is produced. With EV’s, the CO2 is all produced at the power plant(s) - where industrial capture systems can potentially trap/filter the CO2 better before it gets released into the atmosphere. With gas cars, the CO2 is spread out and released wherever the car happens to be. EV’s help keep the air in big cities much cleaner. Industrial scrubbing (cleaning and filtering) systems don’t really exist everywhere right now, but are actively being developed and are nearing viability. 2. The extra cost of catalytic converters, exhaust systems, etc in gasoline cars. If you’re going to consider the batteries in EV’s, you should consider these components of non-EV’s. And 3 - the most important factor of all - which doesn’t relate to CO2 at all - is energy versatility! With a gasoline car, you are locked in to using gasoline and only gasoline. A single energy source. But an electric car can be powered by coal, or nuclear, or wind or hydro or solar or any other mechanism that produces electricity. If push comes to shove, an EV can be fueled at home with a solar panel and inverter. They will be in extremely high demand after the zombie apocalypse! 😁

Completely forgot to include the emissions cost of drilling, pumping, shipping, and refining oil, and the military cost of soldiers and sailors lives keeping the supply lines open, through endless patrols and the occasional war.

The relative low efficiency of the internal combustion engine is only very marginally linked to the fact that mechanical energy is being generated in 1 of 4 cycles. It is strongly linked to how much mechanical energy is being "captured" in that one cycle it is being created and how much is being "wasted" (as heat, mostly). 2 stroke engines have lower efficiency than 4 stroke engines.

One thing isn't mentioned: The slave children that work in Lithium mines. But most people in our rich countries don't care about that. It's far away and out of side. In my opinion electric car's are not greener, but more Red of blood and suffering.

It's as simple as this imo: If power generation became completely green / emission-free, then how much pollution would each vehicle contribute? 1. ICE: some 2. Electric: none and since we're working towards switching power generation to completely green sources, it's fairly obvious that we should also be working to switch all cars to completely green source as well.

There's bound to be teething problems with EVs but the big win is that people are beginning to see them as the norm, and so there is potential for development of cleaner technologies off the back of them. It's taken a century for people to think of electric cars as real world and not sci fi, so let us appreciate how this baby step helps us all.

You neglected to note that to produce 1 gallon of gasoline (petrol), it’s takes an *additional* 1.2 gallons in the extraction, refining, and shipping of oil/gas/petrol. So you should at least double all of the ICE emission numbers. Further, the source of power for EV (for grid powered) is getting cleaner every day and will eventually be 100% generated from renewables and other clean technologies, all over the world. EVs also require far less maintenance since they have roughly 1/10th of the moving parts that ICE cars have.

I would love to see you produce a similar program about the humble lightbulb!

The issue is not the electric car, it is electrical generation. Gasoline vehicle will always emit CO2, electric cars could be zero but for the generation. All steps of producing a car could be powered by zero emission power and that simply isn't the case for gas. There are synthetic fuels that work in ICE, but what an inefficient cludge these are to produce. Plus, charging cars at night stands to balance grid demand which is a good thing for overall efficiency per unit energy

As someone with an EV, I can say a few dated statements, but most are good. It is now over 10% of cars sold are EV, up from your 9%. Most car batteries are under warranty, and most of the Li-ion batteries coming from wreaked are reused currently. So, it is only bad batteries that are being recycled. I will give you Li recycling is a young growth industry, but it exist. There are some cars which charge at rates over 120kW, which gets an EV 20% charge to 80% in about 20 mins. I am sure someone with more knowledge of CC could say more with this.

Finally, a non-biased evaluation of EV's. It still amazes me that car companies can call EV's zero-emission in their ads. That is a flat-out lie, and last time I checked, that is illegal.

the negatives with cars and electric vehicles still needs to be solves before we adopt or change to it. clearly at this point we must stop using and making cars until we have a viable solution.

My understaing is that CO2 is only part of the problem of vehicles with an internal combustion engine. CO and other harmful emissions cause pollution locally, which electricity is produced efficiently by power stations (if not from renewable sources). I think the development of EVs will form part of the solution moving forward; for instance, combined with a hydrogen fuel cell onboard the vehicle.

Lunacy on stilts that's what we are dealing with. The UK is importing wood chips from North America to generate power instead of high quality coal on the doorstep.

Thank you for the great video. It explains the issue very well. Possibly the only one video in youtube that captures the big picture.

Very good. One more potential advantage of electric cars is that being simpler mechanically, less maintenance may be required and thus with proper maintenance, the useful life of the car may be longer. Internal combustion is a violent process that generates wear & tear on a lot of components; EV much less so. Of course, that's a potential advantage, depending on actual maintenance habits but also willingness of manufacturers to provide economical ways to replace batteries when performance drops, but the car otherwise still have lots of life left in it. Also depends on people not wanting to get a brand new car every 5 years or so. Which may actually be the biggest issue here.

@ArvinAsh

I would expect lower maintenance costs long term. Although EVs on the market today have not proven to be so.

Skoda, a VW-owned company, delivers its electric models to the customer's door with a CO2-neutral balance sheet.

Even if different people and country drive differents amount per year, but perhaps a better statistic is what is the average life time of a car in KM? And i would say almost every car produced at least is drive up to 100 thousand kms if not more.

One thing that this presentation misses is that GHG emissions are a system wide issue and that at that level an emphasis on battery EVs makes far less sense until we have first eliminated the use of fossil fuels, especially coal for electricity generation and other purposes. As an example space and water heating are major consumers of fossil fuels, but heat pumps for those purposes often have COPs in the 2-4 range. Fossil fuels used for this purpose are then 25-50% as efficient and the heat pumps do net require high density energy storage. Also, although EVs are more energy efficient than ICs as noted, hybrids make up part of that gap and use existing infrastructure. To me the most effective way to reduce GHG emissions globally would be to emphasize, and optimize, hybrids rather than full EVs, and eliminate as quickly as possible non-transport related uses of fossil fuels, especially coal fired power plants.

Thank you for this interesting, and informative video. But it is a shame that you couldn't investigate the costs of battery disposal and recycling. If electric vehicle manufacturers like Tesla had to directly pay the costs of battery disposal their profits might not be so huge, and their share price so high. But I'm betting the cost of the clean up will be left to the taxpayer. As usual profits are privatised, losses socialized and the environment loses again so that billionaires can boast about how rich and clever they are.

Another amazing video👏👏👏👏

What EVs have that ICE doesn't is POTENTIAL. ICE can't get much better, but EVs can.

Excellent talk

"There is no such thing as a free lunch" EV cars need Lithium, Cobalt and other metals - the UK are stopping sale of fossil fuel cars in 2030 and an estimate I saw that there are not enough mined materials world-wide to satisfy the demand of the UK alone - let alone a global transition to EVs. Add to that growing demand for the same materials for other technology and the wasteful cycle of phone upgrades etc. and there are rough times ahead. It also doesn't address the child labour and appalling conditions in the mining industries, esp. for Cobalt. Another point that is not addressed is where is all the electricity going to come from for charging? The UK and much of Europe has been worrying about the need to ration electricity this winter over gas prices - and currently charging a car in the UK is more expensive than filling a petrol tank because of huge energy price hikes.

You calculated the carbon cost of producing gas versus electrical engines, but you didn't consider the fact that electric engines last longer and therefore fewer of them have to be manufactured.

You also have to take into account that an EV cost about the double of a gas car, this cost can be also measured in work hours for the customer try to buy the car, hour working and generating more CO2. En general the EV car will not impact significantly on CO2 emissions, will be good, but for cleaner air in large cities (no doubt is a good thing) and for the global account of some car companies.

"Travels in",, I remember a physics professor telling me that the majority of charge flows on the surface of the conductor not through it. If you want to increase current flow you use lots of strands instead of one wire, in doing so you increase the surface area.

Batteries currently pose many problems that may be reduced or eliminated by future battery and recycling technologies. Science is working on batteries with no exotic minerals so we may end up with batteries made mostly of iron, which is plentiful, benign, and easy to recycle, for example. Also it's good to remember that the substances in current lithium batteries are not consumed in use, so if we can figure out a viable way to recycle them, we can actually extract 100% of the lithium to reuse. So we shouldn't limit our thinking to imagining that batteries of the future will have the same problems as batteries of today.

I agree with positive impact of EVs , but nevertheless I have 2 remarks concerning the magnitude of this positive impact of EVs 1) Assuming that passenger cars represent 8-12% of the emissions, I find it mutch too optimistic that all these cars can be electrified. Many (50%?) drive in countries with a very poor grid infrastructure, so electric cars are not an option. 2) By calculation the pollution caused by electricity production you use the energy production mix of that specific country. But if tomorrow electric cars increase the electricity consumption with 10% than we dont have automaticly 10% more green electricity, so the energy mix becomes more polluting. In this case the electric cars consume the green electricity of other users. Electric cars will be a more substantial improvement if we have a surplus of green electricity in the year 20??.

"overall" is a misleading concept. It matters a lot if the pollution happens next to where you live or not. It is true that moving everything to distant factories merely pushes the pollution around and hiding the impact, but location does seem to matter when you are biking around cars and you can't breathe. Also, consolidating pollution to central points can lead to efficient solutions to filter or treat that pollution. We may be using gas to generate electricity, but it is preferable to use household lightbulbs than gas lamps in our homes.

Great video! I'm not an expert on the topic so can't really judge the accuracy, but it seems to me like you've quite objectively summed up all the major points, both pros and cons. That's such a breath of fresh air compared to all the fanatics, be it fans or haters of EVs. From what I've learned, it also seems like nuclear is indeed much, much superior to burning fossils, in almost every possible way, so I can't fathom why so many countries are still burning fossils instead. Sure, maybe solar, wind, etc. are even better, but we have to stop burning fossils with utmost urgency, and relying purely on renewables in the very short term doesn't seem realistic for many countries. Any country that can't rely purely on solar, wind, hydro, etc. should at the very least switch from fossils to nuclear.
