I think the section about bike lanes, walkable cities and public transit could have been longer (maybe with an example from Barcelona or the Netherlands). It's far more effective than just electrifying cars.
Hoping there's a future episode coming that spends more time on the importance of reducing car ownership in general than the brief footnote here. When cars are necessary, electrification is good. But reducing how many cars are necessary in the first place will reduce carbon emissions at the source, and therefore require less output from the grid, which will continue expelling carbon for a long time while renewables come online.
Wonderful video, as usual! Could you also cover in a future video the less talked about problems with going electric? Such as: 1) the efficiency loss based on temperature (not just by running the car in the cold, but also the heating of the inside so the humans don't freeze) 2) the environmental effects of road building industry which, if I recall, is worse than the car industry for emissions 3) the ethical and environmental impacts of electric transport. Batteries need rare, toxic, and often unethically sourced materials such as cobalt 4) and of course anything else you guys dig up Thanks for such high quality and educational videos, always make my day better :)
This video skips rolling stock like Trains and Trams. Which avoid the need for mining of harmful battery resources and can be used for frieght transportation today. Hopefully they cover this in the next episodes but it not being mentioned here is a big misstep
I am a bit mixed on this episode. Yes, it is important to replace fossile fuel transportation with other, more renewable modes, but this episode kind of sounds like something that could be heared from car companies which are already switching from the fading fossile bases to renewable. The best change would be to eliminate the need to travel distances that require cars altogether. You have mentioned designing pedestrian friendly cities in the title, but that was more about electric public transportation. it might be viable in europe, but in R1 zoning suburban sprawl in the US, it is just a dream and would require cities to change faces just like they did in the 60s when they were bulldozed to make room for cars in the first place.
This was good, but it focused too much on batteries, which are not a panacea. For cargo trucks, the solution is overhead transmission lines, not batteries. For personal trucks, the solution is getting rid of them, not batteries. For planes, the solution is high-speed rail, not batteries. Batteries are really only suitable for electric cars and smaller vehicles.
There was something I saw that was interesting. Somewhere in Asia a public train network decided to put a train station in pretty much the middle of nowhere and that area started to develop with more and more people coming to live there.
I just bought a hybrid last December. With the length of the warranty I'm hoping it will be the last fuel-powered vehicle I buy. (Because maintenance costs were the driving factor in purchasing a new car.)
I've always liked the idea of putting nuclear reactors on big cargo ships like the navy does with aircraft carriers and submarines, it would virtually eliminate their carbon emissions. Of course it presents it's own danger if the ship sinks.
I think it’s actually kinda funny how years of anti-nuclear sentiment made me think you were being sarcastic for a second. But yeah, absolutely true. There was actually a civilian cruise ship that tested the waters (pun intended) with nuclear in a civilian application. However anti-nuclear sentiment shelved that project pretty quick as country after country banned the ship from entering its ports. Personally I find oil tankers to be FAR more risky to the environment, both from potential oil contamination but also from the fact that crude oil can cause a literal explosion if not handled correctly.
I think the section about bike lanes walkable cities and public transit could have been longer (maybe with an example for Barcelona or the Netherlands) it's far more effective than just electrifying care. This video was so amazing keep up the good work love you guys so much and thanks
I think another big thing that's necessary to speed up EV adoption is requiring landlords who provide parking to also provide EV charging infrastructure.
I live in Utah, frequently, because of the geography and emissions, our air is worse then Beijing. It's funny that people will blame it solely on the mountains, as if Beijing didn't have its own weather and geography to blame for it's conditions. Sure, there's not much to be done now, can't remove people or the mountains, but SOMEDAY, technology will save our air. We just got to encourage it.
Yeah, most US energy doesnt come from green sources. Also, there arent enough rare minerals to completely democratize electric. It seems a bit problematic. I dont see the future with everyone having a car. This video hits a lot of nice points. I hope the US can make some zoning changes to make for a bit more vibrant cities. Infinite subirbia is the pits
Cargo ships could be nuclear. The U.S. Navy has a boat load of experience. In fact oh subs the reactor's are modular. But those subs and aircraft carriers I've been told cannot dock in Europe.
In 2020, when nearly everything was closed because of Covid, the upside was the absence of cars. Streets were empty, clean, and quiet. Sadly, the cars came back.
In Brazil all cars already have the possibility of being run by gasoline or ethanol (alcohol made mainly from sugar cane), and the prices are basically equivalent
7:20 America was built from the ground up around car culture. Almost all of our cities are designed around people using cars for transportation. And unfortunately, 1 of the 2 US major political parties has a vested interest in keeping the country dependent on the car. Which leads to making pedestrian cities unfeasible politically on a large scale.
I use a bicycle in my daily life. I haven't owned a car in years. Build the infrastructure for bicycles, trains, trams, pedestrians. Build the walkable city. Invest in the alternatives to cars, and people will use them.
The reason manufacturers make EVs “luxury” instead of cheap is because for people to want to change, it needs to be an aspirational item instead of something nerdy and uncool. Also because it helps the manufacturers scale by going top down. I think there’s a disingenuous implication towards companies like Tesla (they were pictured while saying they focus on luxury instead of cheaper cars) but they’re literally the company that started EVs being a thing people wanted. (Nissan leaf and that little Mitsubishi thing both coming before widespread Tesla proves my point) EVs have existed forever but nobody actively wanted them. Now they’re a sign of success and everyone seems to want one
Carbon neutral jet fuel made out of atmospheric CO2 already exists, but it’s not as profitable as fossil fuels so it doesn’t get used. And production for profit instead of need is one of the biggest contributors to climate change and pollution. We need to not just improve technology, but improve how the economy works.
2023. If the Gov wants EV to be the way they electricity will need to be cheaper that Oil fuels. Example PG&E paying shake holder is not cheap and makes for bad decision on profit over cheap, safe, reliable energy. The lack of Infrastructure is a huge issue. I live in CA and commute to from the valley to the Bay Area. It’s cheaper for me to use gas than to buy EV and charge it. There are no charging station at work. Other notable problems to be solved. Cold weather. Charging stations. For profit energy production. These are just some of the things that have came up over the past few years.
How about government taxes car manufacturing more and takes that tax money to invest in public tram, trains and proper cycle lanes/facilities, not unlike what Singapore did. we need to look at the pros and cons of different countries legislator and take the pros from each system, take the pros from the Finnish education system, German workers rights, Finnish prison system, Dutch public transport system, Norweigen free roaming laws, Australia's healthcare rights ECT, ECT. We as a people also need to protest, vote, pressure government for change and sign petitions. We also need to change our consumer throw away habits aswell
Your electric car is only as clean as the electricity you are using to charge it. If your area generally burns fossil fuels for electricity then your electric car runs on fossil fuels.
Can anyone help me access the next video in the series? when I try to go to the playlist this episode from two weeks ago is the most recent one I can access and it says "two unavailable videos are hidden." Am I doing something wrong? Do I just have to wait?
While this is good, the current supply and demand need to be addressed, there isn't enough supply to electrify the demands of the countries promises, and even if a new source of these critical metals was found it takes a rough decade for mines to open upon discovering a economically viable source so unless new ways to get more efficient recycling or new forms of battery are found its still going to take a long while to hit the green future. I'm all for making a greener world but people need to know where the obstacles are as we simply can't make all vehicles electric.
2:40 rich people pay to have better environmental quality. It's always been that way in the US. On every single metric rich people have it better than poor people from standard of living to life expectancy. I don't see the US being politically able to reform this system without massive systemic changes that are politically and economically unfeasible such as dismantling American style capitalism.
ammonia is nice but haber-bosch is energy & carbon intensive and it's used to produce fertilizer, cars competing with food or enough haber-bosch to make even more is no bueno
I completely agree that we need to switch to electric and solar, but we really need to address the issue with lithium-ion and the water consumption and pollution that results. We should invest in a different kind of electricity for our vehicles.
I'm not sold on public transit. Here in Denver it costs as much as owning a car and the light rail only services richer neighborhoods. Plus because of the pandemic it all smells like illicit things with burnt foil everywhere. Denver's public transit has been permanently disabled as a result of terrible planning.
Any money spent to subsidize any private company in the USA is a misappropriation of funds. If the industry can't stand on its own it doesn't deserve to stand. I'd really like an electric vehicle however I'm going to wait until electric vehicles don't require government subsidies to be successful.
We don't have enough of the metals needed for a mass rollout of electric vehicles on Earth. Plus, mining metals needed to manufacture batteries for vehicles is extremely harmful to the environment to the point of creating a dead zone around the mine where plants and animals cannot survive. We need to adopt hydrogen powered vehicles.

When cars are necessary, electrification is good. But reducing how many cars are necessary in the first place will reduce carbon emissions at the source, and therefore require less output from the grid, which will continue expelling carbon for a long time while renewables come online.
I would also add trams to the equation for public transportation so we have less reliance on batteries.
Wonderful video, as usual!

Public transit is the way to go.

This is not new. That's how a lot of the Western U.S. was developed, too.

Hi this video was so amazing keep up the good work I always have fun with this thanks
thank you for making a video that explains the pro and cons to electrification

Is this host Canadian? The way she says "car" is very Canadian lol
In Brazil all cars already have the possibility of being run by gasoline or ethanol (alcohol made mainly from sugar cane), and the prices are basically equivalent
There's going to be an episode of this show on the Pentagon, right? You know, the single greatest source of pollution on the planet?
I think this was a good, nuanced look at electrification of transport.

Key word that doom this video: central planning and environmental justice.

I keep loving this Crash Course!!! helping me a lot into seeing and knowing new perspectives about our everyday life :) also helping with my career
It is worth to note that EU is working on banning gas cars in 2035.
EU has already banned sales of new gas powered cars from 2035. So the video is actually containing old info.
Long story short, the future is TRAINS!
AND avoid over-consumption (of things that must be moved around) AND over-traveling (just "for the fun" of it)
Can you do videos on operational research
Oh yeah and taxes on gasoline needs to go up.
Off topic by does anyone know what her accent is because I love the way she says carrrs and carrrbon
Constructive criticism: the sound effect on transitions is very annoying and off-putting, please get rid of that.
Show me where you see that ammonia is sustainable! Fertilizer production is one of the major GHG emitting processes humans are using.
Ok fine there is one way of making it sustainable but it is not how it's being made at scale.

One day, before the end of my (hopefully long) life, I would love to be able to ride in a carbon neutral vehicle.

I'm surprised to not hear about hydrogen fuel cell cars, instead of battery.
Yes. Use fuel.
very interesting .
I like how electricity generation has lower carbon emissions than fossil fuels. ❤❤❤

we're publishing this series on a bi-weekly schedule! the next video will be released tomorrow at noon EST :)
not easy.
What about hydrogen from water, water powered airplane, truck or boats
Make poor people richer then they will be more eco conscious
Trains.
But we can use other metals in batteries that will make them more efficient.
Enjoy the videos, but that scene transition noise drives me nuts.
The way of the future. The way of the future. The way of the future. The way of the future. The way of the future.

ammonia is nice but haber-bosch is energy & carbon intensive and it's used to produce fertilizer, cars competing with food or enough haber-bosch to make even more is no bueno
what if we powered stuff on poop
fuel cargo ships with a nuclear reactor and call it a day for the next 20 years.
I completely agree that we need to switch to electric and solar, but we really need to address the issue with lithium-ion and the water consumption and pollution that results. We should invest in a different kind of electricity for our vehicles.
Great video. Please keep social division out of your video!
gotta git that mac n cheese
How about HAARP? We all need to know about the that.

Electricity will *ALWAYS* begin with *FOSSIL FUELS...* *ALWAYS*
Would any one please think of the mac 'n cheese

Those problems are totally valid - but there’s also got to be obstacles related to hydro-powered vehicles. It surely ain’t a perfect solution either
The future will be powered by cat pee.
