Hope everyone's having a great day! I put a ton of time into researching this video, and was surprised numerous times to learn about the differences in lifecycle emissions between gasoline cars and electric cars. It's a fascinating subject and I'm sure we can keep the discussion below civil! (That was a joke 😜). If you were curious about the battery video referenced towards the end, here's the link: http://youtu.be/1mXSMwZUiCU

+mkrakoff you can run diesels on waste vegetable oil, I used to do that years ago in my old Merc. You don't even need to make any modification if you are not living in a cold climate. If you do, you only ned to install a filter heater so the oil doesn't condense in sub-zero temps.

+David Mead Where is this diesel engine that emits close to no emissions? I want one. As far as I know the most recent diesel engine variants are quite efficient, have lots of filters etc but their emissions as you put it are no where near close to zero! In any case as part of their combustion cycle they must emit something otherwise they would not work. Seems like you have made a sweeping statement without any evidence to back it up.

Good Evening, i liked your video, but i believe you failed to mention one aspect of the debate. What about cars that last more than 10, 20 or 30+ years with only general maintenance like with the Mercedes Benz lineup of older Vehicles with incredible build quality. My personal car is a W123 series 3 litre Diesel coupe from Mercedes with over 300,000 on the clock and is over 30 years old and shows no signs of breaking, and the enjoyment of cruising around in a classic Mercedes pillarless coupe is second to none.

Hey professor. Good video. At least for your school system in the US.  I am interested how you do get the gas in the tank? Does it grow there? Any impact to the environment with the production of crude oil? Any related accidents with crude oil in the last 50 years??? How does the crude oil come to the refinery? Do they use electric power there? How is the gas being shipped to the gas stations?? How is it pumped in the tanks? Any political effects on societies throughout the world when it comes to oil? Any wars? a.s.o., a.s.o. Why is it so difficult to count in all the related effects when it comes to comparing gas with electricity? It is always comparing the gas in the tank with the co2 emission for producing the electricity. So why don't you widen your research and do a video with is really useful. Sorry for being unpolite. I am just so fed up with these comparisons.

Did you take into account that a warranty in not the battery's life span, but in actual fact the batteries manufacturer saying we will replace it if it fails in this time frame? I have repeatedly seen electric car batteries go bad and need to be replaced by the manufacturer while it is under warranty, about every 2.5 years, so with the smaller batteries you are just breaking even, with the larger ones you are in the red. Please do factor in the warranty batteries CO2 output as it is not counted in the estimates as the estimates are based off of the batteries never failing in your presentation but reality is that batteries fail and need replacing a lot more than you might think and replacing a single cell in a pack reduces the new cells life drastically and more often than not will result in problems requiring more trips to the dealership, more money and labor and in the end the full replacement of the whole batterie pack as a whole to solve the problem that should have been done at the start to eliminate the whole bad batch as once a single cell starts to go bad it is more times than not the start of a cascading failure. Maybe this will change in time but I'm not holding my breath. So EVs still pollute more at the moment as a whole.

You don't talk about how weight wears tires and brakes more and emits harmful particulate matter. You talk about better for the environment, but if you're just talking about co2 emissions, co2 is fine for the environment. For human life, sure it's not so good, but you do you realize that plants use co2 to photosynthesize? Warm planet is bad for who? You selfish pricks, never thinking about the plants, I for one would be happy if san francisco was the next atlantis, and canada had better agriculture. And who cares about the polar bears really? Currently they are surviving on a frozen wasteland and would probably be happier if they adapted to warmer temperatures. People want to drive around in evs and hybrids weighing around 2 tons to think they are green, maybe there is a con to that choice when pm10 and 2.5 are not dropping in cities, however, no regulations on vehicle weight are being made even though the human health effect from particulate matter is far greater and more immediate than co2. .04% of the atmosphere is co2, water vapor still causes more green house effect, there are also scientific experiments on ways to cool the earth

I would summarized it in this way: no ICE is the way to go and electrical has less impact on the environment overall. HOWEVER, it is also a myth that electric solution is such a big gain to the environment comparing to fossil fuel. Your video missed two important points, that is also a problem on other analysis: 1) CO2 and other emissions are not the only impact to environment. The electric energy produced can be from carbon sources but can be also from apparently benign sources like hydro. Building dams create micro-climates, change the oxygenation of rivers, change how sediments flow thru the river into the see, affect how sand arrives to the oceans, etc. These are usually non accountable problems. 2) the impact on environment in retrieving not only the elements for batteries BUT ALSO for the engines themselves, as they need rare earth materials.

One problem. I live up north our winters are quiet cold. When its cold the lithium isnt able to do the chemical process as well. You do not loose much power once the cells warm up but there is the problem of the cells not operating properly resulting in excessive wear if used. Temp effects the lithium cells both hot and cold, lithium optimal temp is 41 to 113 °F. To me an electric car would be more problems because of the cold winters.

"for the environment .... for the environment" dude, the problem is not only the CO2 on the stratosphere and its effects on climate change that are disputed by many scientists. 1. You forgot the most immediate, true and highest benefit: the cities' atmosphere. If we all drove e-cars we would have cities with air as clear and as fresh as in the country side and almost as quiet too -the cities where most of us do live and work! *No air pollution* with toxic exhaust emissions (CO2 is harmless in comparison) and *no noise-pollution*, means a clearer mind too, less stressful environment, better performance, and most of all you get rid of a number or serious diseases linked to exhaust emissions! I can't believe you forgot that huge e-car advantage! 2. Oil mining from the sea bed, results in the complete destruction of nearby beaches and the ecosystem in a large area. 3. Oil mining is also linked to destructive wars where many people die and ...far more CO2 is produced for destroying and rebuilding afterwards, let alone that people pay the price for all this. The price to drive internal-combustion cars!

Just like the Sweden study (which isn't the most reliable source btw; it was "debunked" many times) you left out the HUGE amount of CO2 emissions for drilling, pumping, transporting and refining the gasoline/diesel plus the tons and tons of litres destroying the environment during a pipeline spill.

I know you were trying to give the best case for gas cars but I would like to point out that there is also CO2 made to take oil out of the ground, to make gasoline, to transport gasoline to gas stations and to make oil for the engines. If you are going to talk about how much CO2 is produced making batteries, you should talk about how much is produced making gasoline too.

Here are some factor to include in the calculation which seems to be a worlds best kept secret or often excluded. - How much energy does it take to refine a litre of gasoline and diesel. - How much diesel can you extract from a barrel of oil. You will find its a minor percentage. - Electricity is generated and distributed on an exiting grid. How much energy is used to distribute fuel in tankers to all the service stations. - Cost and efficiency trend for electric cars and cell manufacturing. Where are these going for ICE and electric. - Finally, how much energy have we used to fight wars to ensure an oil supply. How many people are dead or living with a mental or physical disability. What is the cost to society and energy used .What is the energy cost in having to reactivete the US Fifth fleet and put in a freedom loving Behrin. Lets see future energy blow back on this. Put these in the mix as well and see what the final results are. Oh Tesla giga factory is solar powered.

Pretty thorough explanation, well done. A couple of things I would bring up, though, you can't simply ignore the end of life issues when millions of pounds of batteries need to be recycled. Recycling processes for something like that are heavy on water and chemical use and energy consumption. You talk about one lithium mine in a remote area, but there are others where pumping massive amounts of ground water into evaporation ponds is affecting water supply for nearby populations. As all of the manufacturers push into more ev production more mines will need to be opened, and they own't all be in remote areas. Currently there are thousands of acres of evaporation ponds, it isn't just pure clean water vapor coming off those chemical and element laden waters, are those emissions accounted for in the battery production? (or any of the mining or lithium extraction emissions or just battery production itself?) What is the environmental impact of pumping oil out of the ground, transporting it, transporting it again, refining into gasoline, transporting that, then putting it into a vehicle vs extraction of coal, transporting, burning, etc.. of course blended with the other sources of electricity (those solar panels aren't emissions free, they had to be produced and shipped as did the controllers, inverters, wiring, mounting, etc...). You took a good swipe at it, but a true analysis would have to run a lot deeper...

Issue #1 If Carbon dioxide is a pollutant the obvious answer to curbing it's production is: Birth control as humans produce copious amounts of carbon dioxide through their existence which requires breathing and consumption of resources which are finite. Issue # 2 in my state companies looking to capitalize on the solar power movement are buying vacant forests and subsequently clear cutting them in order to install massive solar fields. All of this is being encouraged through state and local tax incentives. Those "environmentalists" are oblivious to the value of vegetation to the health of the environment and think this is fantastic. These are the same folks who move to rural areas and wonder why there are suddenly wild animals hanging out in there yards after 500 acres down the road were cleared and want the municipalities to "deal with it".

Thanks for the great video! My ONE complaint is that you're analysis ignores a big variable: vehicle class!!! Comparing an economy car like the Leaf to an an average of ALL gasoline vehicles (which includes vans, SUVs, trucks, delivery vehicles, etc.) is hardly apples to apples. How about comparing it to vehicles in the same class? Or, even slightly larger (but ever popular) cars like corollas, civics, fusions, and the like. I think there's a bigger case to be made there. This is also why the high performance sports car (Tesla) fares so poorly in your analysis. P.S. Interesting idea: Compare a gas-powered economy car to the Tesla. Is all that Horsepower really an environmental free lunch?

Great video. Well researched and explained. Good work! I agree that electric cars are the way of the future, but not mainly because of CO2 emissions. This video clearly shows that they are not vastly superior but only marginally superior in that regard. Also I would quibble with the idea of CO2 emissions being equated with "worse for the environment" - there are many other more important environmental factors that make electric cars better like no chance of producing CO or smog and the freedom to use the cleanest and most efficient energy source instead of relying on fossil fuels. CO2 doesn't kill people - CO, smog, and dirty coal plants actually do.

thanks for the comparison. sounds good, except for two points. the cost of the electric car, especially the 100 kW battery ones. for example, you stated that this car would take 5 years to break even on emissions. but, the car cost difference is probably about 4 times the normal car. so, that is a limitation for a lot of people without 150K to burn on a car that only fits 4 people and hardly any stuff. lastly, the amount of electricity needed to replace all cars with electric or hybrids. this is a huge issue that should be realized as this is the actual limitation for electric cars replacing gas powered cars. and on top of that, is there enough rare earth metals to create enough batteries to replace all gas powered cars. i believe the answer is always a grey one. we can and should use both. and yes, the canadian tar sands will be needed in the future to power those gas powered cars, unless you like oil from countries that are not very nice to us.

I tried to find if this has been commented already, but I don't see it. The estimates that put the larger batteries as "more" polluting than smaller don't account for greater miles driven. If you compare a P100 with a gas car and actually use that 100kWh range, I believe it would QUICKLY come out ahead, as the gas car's numbers will grow mostly proportionally and the EV's original input because of battery doesn't change. Your comment at the top of the video about getting a "properly" sized battery hits the nail on the head, I think. Just wanted to emphasize that, as it wasn't mentioned again.

When mentioning the metals inside the battery, you didn't talk about Cobalt. That is a so called 'bloodmetal' mined under awful conditions in the Republic of Congo! Apart from that, I like, that you mentioned Hybrids in the End, but just briefly. HYBRIDS are the current state of technology, when it comes to fuel efficiency and environmental friendliness! Remember, a Hybrid as a much smaller Battery than an electric car, about 1/10th). So you can build about 10 Hybrids with the same amount of battery to build just 1 electric car. For now, building hybrids, is the best solution, and you don't know about the future, do you!? ;D

BTW Pellitized Thorium Nuclear plants with molten salt cooling seem to be the most efficient and most practical method right now to produce more electrical energy, reduce emissions and solve the CO2 "problem". Wind and solar are NOT the best way to do this. Way too expensive to implement and only work when the wind is blowing or the sun is shining (not at night for solar). We need to take a good look at Thorium Nuclear and, if confirmed that this is a good way to go, start construction on the plants NOW.

CO2 is food for plants that convert that CO2 back to O2. Less Co2 in the atmosphere means less food for plants. No CO2 and the plants would die. It that happened we would all eventually die. Am I wrong on this? Reduction of CO2 seems like a great idea until you realize that a large amount of the hype on global warming seems to be a way for the government to raise taxes rather than a way to alleviate the real problem. That is IF there is a real problem. Not so sure about that.

So what's wrong with CO2 emissions? Plants need CO2 to grow and we need plants to eat. The more CO2, the more and bigger plants. Sounds like a win-win situation to me.

I was taught 50 years ago that when energy is changed from one form to another there is always loss. If gas is burnt to produce electricity there is energy loss so burning gas directly is more efficient. If the battery is charged using other methods such as hydro (flooding land, loss of habitat, environmental degredation,...), or solar panels (heavy metals, plastics, ...) then I guess they might be better. I live in central Ontario, Canada, and it seems that 3 of the last 5 winters have been the coldest I have ever seen, and it is already much colder than normal for Nov. 15. Maybe a bit more CO2 would be a good thing.

Sounds reasonable until you look at real life experiences. There are plenty of examples on utube. One has a Leaf starting with a 100 mile range, driving 18k miles per year and the car displays the range of the fully charged batteries. Three years and he has only a 47 mile range. You don't mention that problem. Who would want the car? Nobody. By your own data, if the driver needs 60 miles a day to get to work and home, he needs a new battery pack every 2.5 years. How will he ever get to that 5 year point where it matches a combustion engine? If a person is really environmentally friendly, then the real answer is to buy a high mileage turbo diesel and keep it for 20 years. Then you also totally miss the whole point of CO2. The entire planet is greener with more CO2, 6% since 1979 when we started surveying the earth. CO2 levels started increasing in 1720, the rate has never changed so obviously not related to what man is doing. There are hundreds of PhDs producing videos to explain this, so don't be a puppet a listen to politicians. If our goal is to decrease pollution, high mileage combustion engines are the obvious answer. You also never mentioned road trips. Explain how I could ever visit my daughter in college 300 miles away. Why would I want to spend an extra three hours each way waiting for a charge, unless the car is two years old and needs me to recharge it twice. Why, this is so obvious, electric is not yet ready for the mass market, only a few zealots who ignore the truth and believe politicians.

The Earth is flat, the ozone layer is a lie, there is no hole in the sky, global warming will continue no matter what is done, even if tomorrow all cars are electric, all factories are toxic-free and everyone recycles, it will still happen. That said, I don't care if cars are electric, even though I believe hydrogen cars are a *much* better option, I do care though that they keep the bikes gas powered, even with a loud exhaust people are still oblivious to us and cut us off, and yet some governments want us to ride silently in the silence of the new era.

+Earl Grey I was actually talking about cars like the Honda Clarity and Toyota Mirai that use liquid hydrogen. I actually never knew someone made a water powered fuel cell, that would be even better. Who knows, maybe someone will find his plans on the internet in the deep web somewhere or come up with their own water fuel cell. Things don't always go as "they" plan.

Death666wish hydrogen is much better. Stan Meyer agreed. He and his water powered car are dead and have dissappeared as a result of his cells efficiency and advancement. We should all be flying around in water powered antigravity machines by now but the best "they'll" allow us to use is costly electric, gasoline, or hybrid cars...

There are a lot of preconceived and popular beliefs about electric cars. And I've got to admit I used to just go along with them... Until this video! Thanks ever so much for the work.

I'm gonna stop you at 5:18 - 24.3mpg taken as the average? If we are talking about people who care about emissions enough to consider buying an electric car they aren't buying f trucks, they're looking at cars with maybe a 1.5L engine, making 45mpg at least.

Unless I'm missing something, It seems that you are skewing the numbers to fit your conclusion that electric/Plug-in cars are the most efficient to drive in most/all states. You are using vehicle averages to produce the numbers for gasoline engine vehicles and comparing them to two specific battery sizes. It is not a fair comparison to lump in all gas vehicles and average them to make this conclusion (at least in my opinion). Wouldn't you need to compare a pool of comparable cars to the leaf and take only their averages? I'm guessing if you take a Civic, Corolla, Focus, and maybe an Elantra, and take only their averages into consideration the numbers would be quite different. And these are not even the most efficient gas cars out there, they are just what would appear to be the most comparable to something like the leaf (4 doors, mid-size sedan).

Excellent video! I’m really glad someone took the time to completely lay out all of the facts and statistics because this is something that is commonly misunderstood.
