- Explore the creation of China’s Three Gorges Dam, and find out how the hydroelectric plant generates its power.
--
In 2018, a single power plant produced more energy than the world’s largest coal-powered and gas-powered plants combined. China’s Three Gorges Dam relies on running water, and is capable of producing more energy than any other power plant on Earth. So what allows Three Gorges to generate all this power? And how do hydroelectric plants work in the first place? Alex Gendler investigates.

Two fish swam into a concrete wall, one turn his head to the other and said "DAM"

But that's why people build fish ladders (things on the side of the dam that are like "steps" for the fish)

only fitting recommendation for this comment is the song “Dam Damn” by Päter its great!

The guy that worked on that animation deserves a Oscar, that what arts is.
But can't add captions.........
@@theinvinciblechannelwithsi9895 The problem is that RUclips used to have community captions, but they decided that it was bad for some reason. Now, video creators have to add captions themselves, which is rare, sadly.

Yeah! What's the name of the music?
@@saswotlamichhane5862 A custom one, I suppose?
Did anyone actually manage to find it?
my father worked for almost 40 years in Itaipu Dam. I remember as a kid when my friends' dads (my dad's colleagues) travelled to China to work as consultants. Every year we cheered for Itaipu to keep surpassing Three Gorges. We've since moved away from Itaipu and my father's retired now, but every time we see someone mention Itaipu my father says "your grandpa worked there as a constructor. He always said there was a part of him there. Now, there's a part of me aswell"
Your family's affinity with Itaipu Dam is truly remarkable. While politicians use these constructions as political tools, it's people like your father that commit entire lives to it.
@@falsch4761 I really hope you get to. It is an absolute modern marvel, especially when you consider everything that the corporation that owns and runs Itaipu does for conservation efforts in the area.
Is crazy that the world is still amazed with hydroelectric power, here in Brazil we almost rely only on it. Itaipu dam produces full energy for a whole country (Paraguay) and for most of Brazil, and we built it in 1984!!
A fellow Brazilian I see
I'm also astonished by such a powerful source of energy
Same in Quebec, almost 100% of our energy is from hydroelectric power.
Agora eu não entendo uma coisa. Temos uma barragem capaz de gerar energia mais do que a barragem chinesa, que é capaz de gerar energia suficiente pra alimentar NY por quase dois anos. Mas recentemente o estado do Amapá ficou vários dias sem energia elétrica. Ou falta de energia no Amapá foi por outro motivo?

My parents were the engineers for the Three Gorges Dam, no matter what, I am proud of what they've achieved. It is indeed an engineering miracle!
@Dreadnought 1997 why so rude?

@@TEDEd i think you are aware of the earth time was reduced due to dam.
@@TEDEd quick to resolve the issue, love that
@@explorelonelyplanet3696 that is a massively oversimplified statement
A similar controversial dam called Tehri Dam garnered massive criticism. Uttarakhand is prone to earthquakes and this dam is the tallest dam in India. Some say that if it breaks, half of the state will be flooded.
Same is the case with mullaperiyar. Starts and ends in Kerala and constructed during British period. Needs a lot of repair but Kerala has no acces to even a single drop of it and have to go to supreme court almost every time to get access for inspection and repair or even to reduce the water level.
If breaks, midland Kerala wipe out.
three gorges can flood everything if hit by a missile (literally impossible to defend)
great warning if china gonna go to war
I haven’t heard “turbine attached to a generator” since 7th grade science class and now I have PTSD.

"this dam(n) rivalry is far from over"
The purpose of the dam isn't only for powering, it's also for controlling the flood. It has been doing a great job at it this summer.
I thought RUclips was banned in China.
@@herp_derpingson yes it is

They did this in the South to my family’s farm. My great grandpa’s childhood home is there, interesting to see
I'm in Tennessee and the TVA (Tennessee Valley Authority) did this to an entire town right near me. Old Butler.
The touch of Samba music to the ost whenever Itaipu is mentioned was astonishing
Do you know what music is played in this video?
okay cool but can we talk about how good this animation is... Ted-Ed never fails to deliver. Thank you.
We are talking about it. It’s literally talked about in *every single video*
@@Brandon-hn5xy thank you for sharing your thoughts but I was talking about this video in particular, the one I replied to...I didn't know that when someone comments it apparently applies to every other video as well...
Easily one of the best dam videos Ted-Ed has produced yet.
I'm glad you raised the issue of sustainable energy development at the end
I live near Foz do Iguaçu (city where Itaipu is located), lots of beautiful things around there, it's truly one of the most underrated travel destinations, so many unique cultural, natural and engineering wonders
As a Congolese the , Inga dams are far yet from being finished. With the corruption killing the country I don't see any developments there it has needed renovations ever since but nothing till now. Sorry for the rant

Awesome animation. Thank you for the update, TED-Ed..!! :)
Every video has its own animation style which is just amazing
I'm from Chile, here we have some dams here from rivers flowing from the Andean Mountains and in spite of the power they produce, the enviormental impact over native flora and fauna are devastating bc of rivers flowing with less water.
You may be a very chile dude
It is incorrect to think that the dam causes less flow in the river. The water flow shall be the same. The water only passes the turbines. The water flow in = the water flow out.
It is not the lack of flowing water but sediments that are blocked by dams that cause damage to the downstream environment.
@@robw6954 Do the fish just swim through the turbines?
@@calvinhoward3808 there will be fish passages constructed next to the dam
"This dam rivalry" , genius
What a calm yet informative video, I like this channel. Congrats Ted Ed!!
What a magnificent animation! Truly breathtaking.
There's also the impact on wild life, some scientists believe the constuction of Three Gorges was a signifigant contributing factor to the extinction of the Chinese River Dolphin, one of the few fresh water dolphins in the world.
can we really weigh this against the thousands of lives saved from floods downstream? 150 species go extinct every day worldwide, strange nobody cares quite so much about those
@@goldsilvervscrisiscollapse4320 I like dolphins more
Actually, the number of Yangtze dolphins have been steadily in decline before the dam was built. Saying the dam contributed to the extinction of the dolphin significantly is an overstatement.
@@ThePickledsoul they can record their genomes and 3D print some later.
The dolphins was declared extinct in 2004. Oh, and currently Yangtze River is currently in a 10-year no fishing period (illegal fishing punishable by jail time). Yes it is "cruel" and lot of fishermen lost their jobs, but fishes also need a break... (Of course the government have a employment assistance plan for the affected fishermen's)
수력 발전 댐은 정말로 단순하게 태양으로 부터 생성된 물입자의 위치에너지를 다시 우리가 쓸 수 있는 전기에너지로 변환하는 과정이라 생각했는데 그 과정이 단순하지 않고 많으 노력이 필요하다는 사실을 깨닫게 해 준 고마운 영상이었습니다.
These artists you guys have are crazy amazing
Somebody says it will break down, but it's been 27 years and it still works...
going straight to comment section looking for dam jokes
Most arguments go, "DAMN YOU!" and "Damn you more!"
but this one is, "I dam me!" and "I damn me more"
I see Brazil and the national wonder of my country that is Itaipu, I upvote. An excelent video like always ted-ed!
Itaipu is a bilateral DAM it belongs to both Brazil and Paraguay
Having seen it in person. I can vouch it was a marvel 🤩
The art in this is incredible
Dam, that’s a lot of energy!!
This is one of the few things I think China was right to do, the immense energy output was worth it.
The only thing I think they should have done differently was to put more effort into the relocation program as to make it not so difficult for those being relocated.
If China and the rest of the world want to swap from coal and fossil fuels we're going to need dams like these.
Some may want to critique the idea of destroying historical monuments. And I do think that's a valid reason, but in doing so we're also creating more issues as there will be less space alloted for progression and more space reserved by historical monuments that we refuse to remove. It would seem heartless to destroy it anyway, but in terms of advancing humanity, a huge focus on the past is actually quite harmful if not handled properly.
Your videos r didactic and more simply understandable. I wish I discovered you guys earlier 😄
Because of TedEd I've come to realise..
Music is at it's best when it accompanies wonderful narration.
The amount of water held behind the 3 Gorges dam changed Earth's day length by changing its angular moment of inertia.
ruclips.net/video/6achMwLwPUE/видео.html
What? Sounds unreal
Source?
@@djtan3313 , I believe the Yangtze's source is the mountains near the Tibetan border, but for more info about the dam changing Earth's day length, search "three gorges dam day length" and read away.
Nasa are also in on it.
Apparently, Earth's rotation was slowed, something I couldn't remember when I originally posted.
@@massimookissed1023 cheers
I thought the controversial part would be about the rumors about the 3 gorges dam integrity, and maybe also about the ecological effect dams have on the environment.
It because on Google map the picture is distorted (China uses a different GPS coordinates decoding method so massive structure will look distorted). Taiwan government using it as anti-PRC propaganda for years...
Yes there is massive ecological and environmental impact, villagers had to relocate and temples had to be moved. But the flood controlling capacity (most of China's economy centers and field are in south east) and power generation outweighed the cost... Imagine all that lower been generated by "clean" coal power plants...
@@AaronShenghao indeed. I think it is intellectually disingenuous for TED to call this the "Most controversial" power plant, when literally this year the massive floods in china would have been far worse and killed thousands were it not for the dam... lives, power and green tech vs the immediate vicinity's environment, which will change to favor other animals- it's clean water ffs, and the environment has already recovered
Versus the Fukushima nuclear reactor meltdown which radiates the groundwater many years later and from which many tons of radioactive material have been released into the oceans was less controversial? How about Chernobyl? Seems to me China can't catch a break on any Western media...
@@AaronShenghao ofc it outweighs the cost when you didn't take accounts of human and environmental cost in the accounting. And what kind of excuses is that? Different GPS decoding method? Next time you will tell me the high amount of CO2 generation from china is not because they burn a lot of coal, but because they use different math formula
@@goldsilvervscrisiscollapse4320 In defense of Fukushima, that reactor meltdown happened because of severe incompetency and shortcut taking. For a reactor meltdown to happen, many things have to go wrong first.
@@evankurniawan1311 Per capita, China population produce less CO2 than the US and the developed world. They consume less meat and per household, consume less energy than an average US house. It's called proportion. If you have 1.3 Billion people, of course you produce more CO2, the point you should focus is on how much each person generate.
By the way, also take into account that much of China and India CO2 and energy requirements are outsourced contamination from YOUR demand and consumption. Where do you think the contamination from extracting rare earths to produce your iPhone is left when the product arrive at your country? Who deal with that contamination? Big words for a little mind. The problem is more complex than just pointing fingers when is your own consumerism is the driving force behind worldwide contamination.
Do you remember when China banned plastic waste imports, which came from developed countries from their fake recycling strategy, where it went? Back to their country of origin? No, it was reallocated in other poor countries. When China is no longer profitable to produce your clothes, the batton pass from YOUR contamination will be taken by India, Bangladesh, etc.
The animation was even more better than the paintings produced by all of the finest artists of the world combined.
The BGM is on point.
You forgot to mention, that the water mass of this reservoir is so huge, that it effects the rotation speed of the Earth!
that's a myth, no scientific explaination for that
@@udin2842 L=Iω
Here you go scientific proof of that.
I know you aren't smart enough to know it but you can use Google kid.
@@morningstar3997 it's just an equation. equation doesn't make it real. it's like saying time travel can be done because it's proven by an equation. did you forget about ocean? if dams can slow the world rotation down what do you thing can ocean do?
and just like what you've said, you aren't smart enough. so don't brag about something you don't understand KID.
They didn’t mention the ecological impact. The baiji, a river dolphin, is believed to have become extinct in part because of the Three Gorges Dam.
At least I heard there are photography contests every year downstream to raise awareness of the issue, held by a committee dedicated to the protection of this particular species. Or it might be the other river.
More human lives were saved as a result of building the dam. You mad bro?
Any help the dam provided is irrelevant TBH. At worst it sped the extinction up by a few years.
People fishing is what truly killed the river dolphin off. And poor people on a river aren't going to stop fishing just because they accidentally kill river dolphins while fishing for their survival.

@@lordgarion514 2 species of animal go extinct every day and it’s just a dolphin
@@Imperium10
Actually, there is no single number.
The estimated range is between 200, and 2,000 species per year go extinct.
And that is based on the estimate of 2 million species in total. Could be a lot less, and could be a lot more.
And all of that is absolutely irrelevant. We've added to the number of extinctions, which screws up other things. Not to mention we've permanently reduced the numbers of wild animals by an insane amount.
"Globally, monitored population sizes of mammals, fish, birds, reptiles, and amphibians have declined an average of 68% between 1970 and 2016, according to World Wildlife Fund's (WWF) Living Planet Report 2020. Populations in Latin America and the Caribbean have fared worst, with an average decline of 94%"

It was not a real concern. Some Taiwanese and FaLungong followers spread the rumor.
That's anti-China propaganda you're talking about, according to them, this dam is on the brink of collapse every single summer.
Best voice
What a good video and animation.
Hearing about all these dams destroying natural and cultural sites was depressing. Dams still have problems with silt...over time, the reservoir fills up because the river's natural flow was disrupted and sites downstream lack vital sediment that keeps them healthy and helps prevent damage from rising seas.
but dam still far better than coal for generating electricity, it won't cause any harm if it maintain properly. so i prever losing cultural sites than losing oxygen

Please I'd like to know ways in which one can reduce his losses in the foreign exchange market.
Thank you.
One highly effective way to reduce the probability of regular losses is to follow a trading mentor or trainer. By gaining the knowledge and guidance of a professional trader you will master how to become an FX trader who adopts the correct trading mindset and skillset. And also you can sign up for a fund management service, that will also help.
I tried placing my trades all by myself but ended in a messed situation. I will advise anyone to place their trade under an expert who knows how to handle the trade very well of course a reputable and reliable one
I was once a victim of blown account, losing and failures in Crypto and Foreign Exchange market, until i met a Pro Trading Expert (broker) who is licensed and my financial status changed for good💯✔️
Just a minor nitpick but the turbine depicted at 0:50 seems to be a Pelton turbine and the Three Gorges Dam doesn't have those. It has Francis turbines instead. I know, I know. I hate to be that guy but I spent 2 semesters learning about it and couldn't help noticing 😅

why was there absolutely no mention of the effect it has on villages and other countries down the river. for example, what about in Vietnam when no one can fish because the dam has "stopped the flooding", effectively stopping any water flow to these fishing villages. This has a MUCH bigger impact on neighbouring, less-off, countries
You should first search the Three Gorges Dam on the map to see where it is, and then search the Yangtze River to see where the river is, and you will know that this dam has nothing to do with countries such as Vietnam and India, it is all in In China, the end point flows directly to the sea.
“Prevents flood during rainy seasons” yet massive floods have persisted throughout the Yangtze this year
Well it was also hundred year records breaking rain... At least it helped mitigated down stream flooding
Notice how if anyone posts anything questioning the three gorges dam the bots come out?
@@NPC13377 Oh totally, I was hoping to find some here by making this comment
