How do wind turbines work? - Rebecca J. Barthelmie and Sara C. Pryor
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.
Lesson by Rebecca J. Barthelmie & Sara C. Pryor, directed by Gavin Edwards, Movult.

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.

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.

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.

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.

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.

I wish all my professors sounded like this 😭
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
Such a soothing voice, God!!
I am a third year student with renewable energies, thank you. I have benefited a lot
Happy Earth Day, everyone! It's fitting that TED-Ed made a video talking about wind energy on Earth Day.
This was actually cool, always heard about solar or hydel
Awesome Animation!! Good job, Ted-Ed.
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
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 🌱 🌏
wind is a friend, each people can feel when wind come.
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.
Very informative! Thank you for sharing!
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
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!!
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

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!

We have wind turbines farm in my village on the hill. First time I saw it, I was shocked by the size of it.
The fact that you could power twice as many Eu homes as US homes, really says something about the american lifestyle.
