Hydropower 101 

Who came here because of homework 😅

pretty sure this is the 100th time my science teacher has made me watch this

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

Anyone else here because they're doing physics for home learning?

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

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'm an accountant student but my wife who is an event planner ask me how hydro works. This video is very helpful.

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.

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!

"Damned water." Gosh Dangit, Jimmy! LOLOL School brought me.

Just found this PERFECT video to show my class thank you so much, my teacher thanks you too! :D

I love the videos and I think this will help a lot of students as the explanation was neat and easily understandable

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.

Thank you for talking about the concerns with hydropower as well!

I appreciate the honest cons given at the ends. Thank you. Trying to write a good research essay for English 12.

Had to see this for quarantine

A lot of help on my project. Thanks a lot.Oh and I subscribed.

Hello! Excellent video. Would I be allowed to embed this into my personal website on Renewable Energy and Green Electricity? Many Thanks!

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

I watch these videos for my environmental management exam tomorrow 💕😬

Thank you for explaining this. It's a good, straightforward description.

Thank you so much. I had a test, and you saved me!!!!!

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

Fantastic video. Now, we know about hydropower. Moving water produces electricity.

A lot of help for my project thank you so much it helps a lot

great knowledge like my cousin and what a beautiful voice you have!

I came here because ai wanted to teach my students how Hydropower works. Thank you for this informative presentation.

the narration too is very good

Really good information and explaining!

thanks for this video it helped me a lot in my assignment of hydroelectricity , I had to make a very big report on this , so it really helped , thank s god bless you

Her voice is so relaxing. 😍

great help end information!! amazing narration!! Continuously went back to this video in my research and i found it very helpful for my project for school. Thank you so much and please keep making videos!!! also the pictures were AMAZING took screen shots and used some of them on my project aswell!!! I HIGHYLY RECCOMENEDED THAT MY CLASS GO WATCH THIS VIDEO AND MANY OF YOUR OTHERS

Thank you so much info for my project!

Thank you this makes my homework a lot easier!:)

This video gave me alot of information , thanks 😀

I'm leaving this comment here for the future when I need to do another essay and its a lot more than 500 words...

awesome !!!!! beautiful explanation and amazing animation

Thank you! This is very informative! 😊

good explanation nice speech

thank you for your lesson

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.

no wonder teachers love this video, amazing animations! I also am teaching with this. Thank you!

Thanks I needed that for my test in school
