Hydropower… Hydropower, or hydroelectricity refers to the conversion of energy from flowing water into electricity. It is considered a renewable energy source because he water cycle is constantly renewed by the sun. One of the first uses of hydro-energy was for mechanical milling, such as grinding grains. But today, modern hydro plants produce electricity using turbines and generators. The mechanical energy created by moving water spins rotors on a turbine. This turbine is connected to an electromagnetic generator which produces electricity when the turbine spins. There are two main type of hydroelectricity production. Dams and run of river. Hydro dams utilize the potential energy from damned water to produce electricity. A dam is a large barrier constructed to raise the level of water and control it’s flow. The elevation created by the dam creates gravitational force for turning the turbine when water is released. Some dam also contain an additional reservoir at their base where water is stored to be pumped to the higher reservoir for release when eletricity is in demand. This is referred to a pumped stored hydro. The second form of hydroelectricity production is run of river hydro. Run of river still uses turbines and generators but relies on natural water flow rates of rivers, diverting just a portion of the water through turbines. Because run of river hydro is subject to natural water variability, it is mort intermittent than dammed hydro. There are various of hydro plants that produces electricity. Large hydro, greater than 30 megawatts. Small hydro, 100 kilowatts to 30 megawatts. And micro hydro, less than 100 kilowatts. The Hoover Dam in the United States is a whopping 2074 megawatts, which is enough to serve 1.3 million people. Of all renewable energy sources, hydropower holds largest share of worldwide electricity production. Hydropower has several benefits. It is a cost competitive form of electricity. Even though the initial building cost can be high. It is quite reliable compared to other renewable options and pairs well with other sources as it can be used as base load power. In some cases, dammed reservoirs can also help with flood control and be a reliable supply for communities. There are also some concerns with hydroelectricity, especially when it comes to large dams. Damming a river has a major impact on the local environment, changing wildlife habitat, blocking fish passage and often forcing people in riverside communities to move out of their homes. In addition, dam failures can be catastrophic claiming the lives of those living downstream. Hydroplants are also not completely free of greenhouse gas emissions. As with most form of energy carbon dioxide emissions happen during construction, particularly due to the large quantity of cement used. And plant matter in the flooded areas makes methane another greenhouse gas, as it decays underwater. That’s hydropower.

The largest hydroelectric plant in the United States is at Grand Coulee Dam. Its three powerplants have a capacity of 6,809 MW, and it generates, on average, about 21 billion KWh, while Hoover Dam's powerplant has a capacity of 2,074 MW and generates approximately 4 billion KWh a year.
dear sister you talked 2 things but whats difference between 1: Grand Coulee Dam. Its three powerplants have a capacity of 6,809 MW, and 2: and it generates, on average, about 21 billion KWh
What if the water in the damn drys up?
oh really?
@@Iamtheman325 no electricity production then

Thanks for helping me with my engineering assignments! My teacher loved this video! We are talking about hydroelectricity right now so this was perfect!
First!

Conventional sources of energy have always been blessing to this world.
Superb graphics and nice explanation.Short and crisp things don't confuse our minds. Exactly perfect.
I came here because I was reading Dr. Thomas Sowell’s book: Basic Economics. He refers to hydroelectric dams in page 423 of his Government Finance section (chapter 19). Good stuff. I urge you all to read this book with alacrity.
I'm an accountant student but my wife who is an event planner ask me how hydro works. This video is very helpful.
I have a project to present in physics. Most exactly i need to make sure my group understands how this works so this was as simply explained as it could be. Thank you very much
Anyone else here because they're doing physics for home learning?

No some last minute geography
yep
Had to see this for quarantine
Thx! Really helped me! I hv a presentation to do in a week and my topic is about Hydro tech...I did have a fair idea about dams but i still was a bit confused. But this video cleared up my confusion! Thx again!
I needed this info for a last minute project and I didn't find it clear anywhere. This video is just great. Thanks a lot

Thank you for talking about the concerns with hydropower as well!
Who came here because of homework 😅
Christine Greco me I have a presentation due tomorrow
Bro i have TIPE and this just popped off of nowhere im in tears .

I’m sad
me i have a presentation
Fantastic video. Now, we know about hydropower. Moving water produces electricity.
I love the videos and I think this will help a lot of students as the explanation was neat and easily understandable
Thank you so much, my task was to make a podcast about this topic and because of this video, I was able to finish the task faster
Thank you so much. I had a test, and you saved me!!!!!
Hello! Excellent video. Would I be allowed to embed this into my personal website on Renewable Energy and Green Electricity?
Many Thanks!
the narration too is very good
que
Eeeee
True
hows it goinnnnnnnn
gooodddd@@carsonlemoine7234
Just found this PERFECT video to show my class thank you so much, my teacher thanks you too! :D
I appreciate the honest cons given at the ends. Thank you. Trying to write a good research essay for English 12.
I watch these videos for my environmental management exam tomorrow 💕😬

School brought me.
sheeeeeeeeshhhhhhhhhhh
I came here because ai wanted to teach my students how Hydropower works. Thank you for this informative presentation.
Really good information and explaining!
thank you for your lesson
thanks needed it for project

Very well explained for Students to follow
got a physics test tomorrow and needed to watch this 😎
Will the information be available in PDF format? If so, send
Ive watched this video 60 times in one night, do i need to study this hard
no bruh, just take notes.
Bruh you don’t need to like she said TAKE NOTES 📝
Make one bullet point and ask if it’s enough.....
@@vijjilaxmi985 kinda hard to take notes two years later guys
@@eternallyspoopy2238 FUCKING DO IT AGANE
This video was really helpful. Thanks.
Thank you so much for sharing more information about hydropower
Thanks a lot for this informativ video! It helped me a lot for my school project.
do not forget to go further with Informations about Small and Micro Hydro Power plant! the video is limited in explanation only for huge dams. ;)
Thank you for this information
lower reservoir is meant to store water to be pumped back up when demand is high
Great work. This is a wonderful summery that is short and sweet. What app do you use to make your videos?
Thank you for tall me about Hddropower keep up the good work!
Who is on online school right now?
Just you......

good job i needed it for class work
Great video, thanks.
Nice vid, but there is also Pico Hydro Generators, these are less than 1 or 0.5 KW. I'm building one myself :)
That's wonderful! Where are you building your project?
In Slovenia, but it's gonna be tiny. Probably about 5 watts. I want to be able to use it for charging my phone and powering LEDs. BTW I subbed because your channel is AMAZING! :)
it is a good idea
Woah that's cool mate well done!!!!
@@mandarin1257 they you do it... how it went! Lemme know
I'm here for homework too!
heyyyyyyyyyy
Wonderful i love this explanation type really thankyou
thank you this video is very helpful
Finally got it...
No way....
Who is using this for a project and not paying attention?
very good explanation and graphics....✌️
2018? ThiS iS SomeThing i Was Searching CUZ Unable To UNDERSTAND by NCERT Geo BoOkk !!!

Hey dude go and study......👨🏻🔬.
Lol
Nyc explanation
Your ugly indo not know
*nice
wow you are good teacher and we need more lessons
Listening this as my vacation work
Could someone please professionally caption this? I have to use this for school, and it is quite frustrating as a hoh (hard of hearing) teen when I don't have captions. Thanks!
Better than coal.
thank you!!
Thanks
Because your explanation is to good
