SUMMARY
Electric vehicles are not necessarily greener because they create no emissions. We have to take a look at the bigger picture. Source of electricity, depending on the fuel, can produce greenhouse gases. Manufacturing the components of the car, such as batteries also makes CO2. We review CO2 produced by EVs compared to gasoline cars throughout their lifetime.
EVs are about 9% of all new cars sold yearly, and only 1.4% of all cars on the road. The main issue is carbon dioxide emissions from petrol or gasoline cars which causes climate change.
The common internal combustion gasoline engine is inefficient. Only 20-35% of the energy produced from burning the fuel ends up turning the wheels. But in electrical vehicles, about 75-85% of electrical energy is used to propel the vehicle.
How much do gasoline cars pollute? On average worldwide, a gasoline engine car produces 202 grams of CO2 per km driven. When taking into account the CO2 produced from the electricity generated needed to charge the EV battery, they produce 83 gCO2 per kilometer driven - a difference of 119 gr if CO2 in favor of electric vehicles.
But we have to take into account the CO2 generated during the manufacturing process of electric vehicles. Manufacturing a typical gasoline car releases 7 tons of CO2, whereas manufacturing a similar sized electric car releases 10 tons. So EVs produce 3 tons more CO2 in the manufacturing process.
So, EVs are not greener compared to gasoline-powered cars from day one, when considering that they have a substantially larger carbon footprint immediately after they are manufactured. So we have to consider how long, or how many kilometers they would need to be driven in order to make up for the higher CO2 generated during their production.
The math shows that an EV breaks even after it has been driven 25,210 km. But experts estimate that the average EV battery will last at least 200,000 km. So over the life of the vehicle, in most countries, an EV will be greener.
There are 5 countries where on average EVs will not be greener even over their lifetime - India, Estonia, Poland, Czechia and Bulgaria.
#electriccars
But overall cars only only account for 8-12% of overall greenhouse gas emissions. The most significant contributor to global greenhouse gases, 40%, comes from Electricity and heat production. So finding more eco-friendly ways to produce electricity will have a greater impact on CO2 levels than EVs.
In carbon dioxide numbers, you will create about 19 tons of CO2 over the lifetime of an EV, but more than 55 tons of CO2 for a gasoline car over its lifetime.
Here is an overall summary
• Over the lifetime of a car, an electric vehicles are greener in most countries of the world.
• EVs would not be a greener alternative in India, Estonia, Poland, Czechia and Bulgaria.
• Electric cars batteries may harm the environment unless we can recycle their batteries
• Raw material supplies may be limited which may have a geopolitical impact

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.

@CraftyF0X Жыл бұрын

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.

Mainly because it would make things look even worse. The same mining is needed to get the resources needed for cobalt. Often it is mined together with other things, like copper. Sadly, where there is cobalt, there often is also materials that are radio-active. Making the process, locally, even worse than 'normal' mining. This is why its mostly ignored. Because there isn't much difference, if not straight worse.

At 5:38, the chart shows ~200g/km of CO2 for a gas car. However, it seems they never account for the drilling for oil, the refinement process, and the transportation. If we are going to factor in every detail regarding electricity generation, then we need to do the same for gasoline, comparing apples to apples, not just tail-pipe emissions.

@ArvinAsh Жыл бұрын

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. This also has a CO2 footprint. The main takeaway should be that EVs are greener long term. Any CO2 saved from producing fossil fuels would be icing on the cake.

@KDawg5000 Жыл бұрын

@@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).

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.

@fredhawken1112 Жыл бұрын

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.

@james3876 Жыл бұрын

@@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.

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 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.

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!😊

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.

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. I don't hate the EV revolution. But it's been vastly oversold. Nuclear energy is the only realistic solution to the world's energy problems but its a long way off.

I don't disagree with that assessment. Nuclear is probably not going to be a savior because, at least in the U.S., nuclear power plants take 10-20 years to get approved and built.

A portion of Brazil is already “carbon free” concerning fossils fuels and switching to EVs will not help on that.

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.

Another important point of comparison when it comes to CO2 produced during operation is between electric automobiles and other modes of transportation. 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

@Tenly2009 Жыл бұрын

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! 😁
