- Explore how wind turbines convert wind into electricity, and the challenges of powering the world entirely with wind energy.
--
Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible amount of energy, and is it possible to create a world powered entirely by wind? Rebecca Barthelmie and Sara Pryor dig into the science of wind turbine technology.

I am *blown* away by these Ted-Ed videos
@lewangoalski good*
@lewangoalski thanks, that was the intention
haha, nice
I see what you did there.
@@user-hi8jv6cw8n amazing*
The biggest thing I took away from this is that American homes consume twice as much electricity as European homes 😳. That's insane
Small houses and appliances. Low usage of air-conditioning. Also gas heating and cooking systems are more widely used.
Part of it at least is the obsession with temperature control.
Most homes in Europe straight up dont have ac's
Then the fridges and ovens tend to be smaller.
Essentially its alot of small differences that add up to a large difference.
Americans: I sensed someone trying to take away my freedom/constitutional rights...
It also depends on which part of Europe. For instance, in Southern Europe most houses don't have central heating nor AC
And/or they are half as effectively using electricity as European homes.
For example:
Low quality American homes with high square footage and volume attempting to regulate temperatures because the homes are not well-insulated, which requires a lot of electricity.

Wind turbine: "I have infinite power!*
Albert Bertz: *Well yes, but mathematically no.*
Albert Betz: *You capture about 60% of the winds energy, wind turbine.*
They do have infinite power as long as the generator still works properly, the problem found by Bertz was about was the energy harvested from the wind was only half of its potential energy
Sorry for being too trivial, I know you were just making jokes but I can’t help it, lol
Albert Bertz: Well, you have 59.3% of infinite
Albert bertz:your 0.01% away from being an mortal

Ted-Ed!
Me of course
TED ED
@@googler5879 no
The Organic Chemistry Channel
Between the animation and the soothing narration, this video makes it easy to un-wind. Learning becomes a breeze which makes me watch from this channel with gust-o.
Lol
Her voice is so soothing
4:50 I liked the wind turbine blowing behind the Ted-Ed logo.
The animation is on point. 🤩 TedEd keep improving each time.
The artistic value keeps increasing
Just rename these things *"Freedom Fans"* and America will be completely running on clean energy by the weekend
Edit: Guys, it was a god damm joke
Wind energy is not profitable without taxpayer subsidies. We couldn't afford to run the country on windmills even if we wanted to.
@@DegreesOfThree I doubt that s true. How could they not be profitable when a single turbine powers thousands of homes?
@@RoScFan I'd like to see their sources on that. Half the time, the windmills I've seen don't even move. They break, or there's not enough wind.
@@RoScFan The turbine that powers thousands of homes is gigantic and probably cost 100 million to build, install and maintain.
@@DegreesOfThree They might be deliberely shutdown with breaks due to too much electricity production.
I'd like to say I'm a BIG FAN of wind turbines.
Haha
Haha😐
Haha
Yeah, the potential for this tech is mind blowing
"Some people feel turbines disrupt natural sceneries"
I'd rather have clean energy and deal with turbines in my view than a dying planet with a clear view
I think they can actually improve the view!
Is it just me or does anyone else actually like the view of wind turbines in the horizon. They move so fluidly and are a testament to human adaptability and ingenuity
The issue generally with them is that they are put in nice rural locations where the population is low and power demand is low, they are actually to power some city or data centre 100's of km away so people get annoyed especially due to the negative effects of having to live near them and destruction to the environment to build them.
Same
@@heckerjr.7982 Video no longer available, maybe censorship. What was it about? If I can find the video with other link, please, let me know.
How do people think that wind turbines ruin scenery? I find them quite beautiful
Same it always reminds us of our technological progress
The scenery is already ruined by vast human-made fields. So the objection is already unavailing.
When a wind turbine inevitably needs to be replaced the remains aren't recyclable. It goes to a landfill where it is chopped into blocks and will pollute the earth for thousands of years. But it gets worse, the concrete and steel used to hold the turbines in place is impossible to remove.
@@derklebob8161 source?
Depends on how many there are.
How ted ed shows visuals and how she explains, it feels so easy and clear and thus creating a want to see and learn more.
Nobody: How much animation do you want in your videos?
TED- Ed: yes
that doesn't even mean anything.
@@seaque. It's s meme.
@@mikkokivisto4414 It doesn't mean anything. The entire thing is animation. If it was real footage with animation and animation was too much it would make sense.
@@seaque. Memes tend not to have deep and insightful meanings.
@@mikkokivisto4414 What's deep or insightful about being accurate and logical?
Ted-Ed videos: exist
Commenters who don't want to be controversial: Best i can do is *The animator deserves a raise*
Lol
Thats so true
Reminds me of my road trip out west 10 1/2 years ago. You would be out on the road, and up on the side of the road, and you would see a huge wind farm. My family took lots of pictures, because this isn't something we were used to seeing on the East Coast.
This was a great video on how Wind Turbines work.
Nice animation too,good job,Ted-Ed
4:05 What! I love the scenery of hills with windmills!
whenever I feel board , Ted-Ed will always be there for me.
We have wind turbines in some provinces here in the Philippines. So far, they have been used to create natural energy. Thank you for this video.
I usually don't like those 5min explanation video, but those are just great. My favourite is the subjects are actually diverse and interesting!
I live in America; about 40 meters from railroad tracks and saw a train with roughly 12 of these giant windmills on flatbeds! They are soooo big; One of the best feelgood moments of my life! Build back better!
4:05 what?? Windmills are literally aesthetically pleasing!! That power grids and electric towers or whatever you call them.
This animation fits so well with the topic. Keep up the amazing work TedEd!
I'm just amazed on how much time and effort is taken by the people of TED-Ed in making these videos, thanks!
Scenery depends on perspective, I personally think wind turbines makes for quite a nice scenery
With an Exuberant animation 😍 and good narration you're the best teacher to teach with joy 🤗and it made our learning joyful ☺️. We'll keep Supporting You Ted-Ed 🥰
I am a third year student with renewable energies, thank you. I have benefited a lot
Great explanation of the lift force that's generated from different blade designs. From my limited knowledge of these from only two classes in college (24m) covering them, I never made the connection (or professors never made the connection for me well enough) between translational wind movement and rotational rotor movement. This visualization cleared it up pretty well!
ft Not m
@@byronchavarria4954 its foot not ft and it's meter not m.
@@jonahjerryson4913 It’s Abbreviation
@@byronchavarria4954 It's abb not abbreviation.
The fact that you could power twice as many Eu homes as US homes, really says something about the american lifestyle.
This is amazing. We are doing this at school right now. I love you TedEd!😁
The problem here in Northern Europe is that we need the most electricity in the winter, when we need to heat our homes. But that's when there's no wind.
Is that the same with hydropower in winter? cause the reservoirs and rivers may freeze.
@@jk-gb4et
The water isn't stationary so it doesn't freeze. But there is more water in the spring and less in the autumn / winter.
Don't worry, Scotland and Ireland will provide: plenty wind here in winter, more than enough.
Wait i thought winter are the best time for wind to goes on?
@@lyricalarchives8341
No. There's almost no wind in the winter, and the air weighs less too, so less force in the wind. Wind power sucks during winter.
Wonderful episode! Thanks for the knowledge, as always :)
I can see why Wind Turbines are really important now! Thanks for this video TedEd 😊
the animation is so cute. I just can't--
Can’t what?
@@TheWendable it's just an emotional exclamation... that something is soo amazing that u R left speechless.
TedEd always blown my mind al the time like a breeze that spins my brain into new things to learn.
Thank you for the video! i love the style you used of kinda slowly thuroughly explaining it. I already knew mist of it, but its fun to listen to. As someone who has massive dream to work on build and repair these, i cant wait. Thanks for time
POV: you already knew how wind turbines work but it's a Ted-Ed video and you clicked anyway
Yup.
This whole video is just fantastic. Thank you.
Ted-Ed never cease to amaze me with their contents. - very educational
Guys it ain't always about the animation, Ted-ed is tryna inspire a new wave of energy dependence, and anyone could start it. We need to learn more and take upon this task
Thanks TedEd! Knowledge I didn't know I needed.
People don’t realize how big a wind turbine is until they see a 200 foot blade pass them on the highway. Canada has a lot of them and they are still being built in southern Ontario but there’s sadly a lot of controversy against them from being a sore sight to people having headaches from them.
I have heard geothermal energy mentioned a few times, but not really explained in-depth. Do y'all think you might be able to for us?
Happy Earth Day, everyone! It's fitting that TED-Ed made a video talking about wind energy on Earth Day.
just finished watching a couple kurzgesagt videos about nuclear energy when this came up. so happy we're talking about the importance of these things!!
풍력 발전이 바람의 힘을 이용해서 이를 에너지로 변환한다는 사실을 알고 있었지만 어떠한 과정을 거쳐서 바람을 전기에너지로 변환하는지에 대해 궁금증이 많았습니다. 그 부분에 대해서 잘 설명해주셔서 감사합니다.
Windmill uses to grind grain into flour and milled by winds, to pump water and to generate electricity.
Awesome Animation!! Good job, Ted-Ed.
I wish all my professors sounded like this 😭
Happy Earth Day 🌱 🌏
Always amazing and creative
Love all videos thank you so much for uploading such an informative video..... please upload still more videos with which I'm getting updated all the time...and I'm learning,knowing new things around the world by watching your videos...
All the best...
God bless you....
Very informative! Thank you for sharing!
This was actually cool, always heard about solar or hydel
Such a soothing voice, God!!
"The wind is an untamed and unharnessed force." - Abraham Lincoln
Not anymore
If you say that anywhere else but this video people will think it's just one of those fake Abraham Lincoln internet quotes
@@bernardoquina3047 This quote was displayed in the start of the video.
@@bernardoquina3047 whats wrong with sharing quotes
Why is TED quoting white supremacists? Shame on them.
This video does little to really cover wind generation, it's practical difficulties in using it to supply a grid and the very real intermittency problem. In the U.K, since the 9th April to date there has hardly been any wind generated power fed into the grid for example.
At 4:18 it makes the frequently stated view that it is cheap, it is quite the opposite it is very expensive due to the cost of accomodating it's technically unsuited power and the very large subsidies.
Power the world entirely with wind, not a chance, it is completely unfeasible.
Your voice and the way you speak is so relaxing
Like, I just woke up and I am sleepy now xD
The view from the top is amazing.
I'm interested in all sort of renewable energy.
wind is a friend, each people can feel when wind come.
I am watching from Philippines 🇵🇭
We need to cover the new gyrating vertical turbines because they’re amazing
Excellent explanation.short and sweet
4:17 you forgot to mention Hydropower ! one of the best and cheapest one
Building a dam is expensive
POV: you clicked the video just because you like the aesthetic of the wind turbines
Woke up to the notification of this video. I'm sure I'll have a good day 😊.
Renewable energy is the best source of energy
Imagine making a solar wind turbine. Not only will the turbine produce solar energy, but it will produce wind energy as well. So if you made wind turbines that also had solar panels as the blades and body.
A daft idea for more reasons than I can be bothered to list.
Source for the "Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day." figure? Would have thought that (all) wind would have much more kinetic energy.
These kind of videos *blow my mind*
So cool 👏👏👏
The best teacher award goes to⭐⭐⭐
Nice 👍👍👍
Great 👍👍👌👌👌
This video was just the right amount of time. I can't stand long-winded videos 🥁
Ted -ed never disappoints
5:02 You must take hydropower in consideration, which is considered the cheapest source or renewable energy. On top of that hydropower can supply power in the magnitud of GW
We need more of these here in Texas.
Two questions that were not answered:
- How wind turbines actually turn kinetic energy into electricity (electromagnets)
- Where wind actually comes from (the uneven heating of the planet)
Yes correct. Exactly
We have wind turbines farm in my village on the hill. First time I saw it, I was shocked by the size of it.
Animation is blowing my mind
This one had some of the best animation
Exact animation perfect
2:26 Snow too, if you don't neglect to winterize them.
I love Ted-Ed💖💖

Eternal breeze...I can feel its freshness
happy earth day everyone and every day should be earth day.
What happens after a wind turbine is used for 20 years? Is it possible to replace or even to repair parts, or is the structure of the turbine damaged after such a long time so it has to be dismantled?
"Is it possible to replace or even to repair parts" Yes, they often go through maintenance throughout the year - the jobs pay pretty well too.
Nice video! 👍🏻
Whoo, another ted ed video
I would love if the world would one day run on renewable sources of energy because it would be so much more eco-friendly. But people are so much afraid of changes. :(
Everyone would love that!
@@dimlighty ikr!
Not only that, but it would also never run out
Yes agree, we need nuclear power.
On a trip to California, I saw a crow die in the blades when I was 8. That's the only time I've seen a windturbine.
I live in California..
I can hear the lady say anything so soothing voice
Can we talk about the ressources needed to build all that amazing wind turbine please ? And all the impact on the environment ? It’s a good way to generate renewable energy but it can’t work all alone. We need an energy mix with wind, solar ( with some Storages), hydro and nuclear too (yes even if you don’t).
But you have to work on sobriety to improve the result way more that you imagine.
Technology and efficiency are importante but we have to work together on all fronts and never let some solutions (nuclear for exemple) on the side of this difficult road named Climate change that humanity need to cross right now and for the next decades.
So what do we do with the blades after 20 years ? I hear they are hard to recycle/process. We're actually "buying" wind energy with our energy supplier, and I like it a lot, but this is still something I worry about.
This helped me a lot
Imagine you build an equal size wind turbine in front of a fan, cooling effect is vastly reduced, one has to imagine cooling effect also. super smart!
What about utilization of those blades?
Winds are generally generated due to energy from the sun.
It was an advance GK video...rather being of machanism...but still fascinating.The only thing I learnt is Netherlands is doing good
Nice information!
the outro is SOOOOOOooooo creative damn
