Consequences Of Hydroelectric Power


What are the good and bad consequences of hydroelectric power? You know what a dam is. What happens because of one?

What are the problems of a dam? For one thing, many fish are killed trying to get through the turbines and going through the turbines makes the water very hot. With the dam being there, areas beyond the dam have very low water supply and behind the dam they’re often floods.

According to the world they’re many different consequences. Some like there is no pollution, water is renewable however the water of a dam rises or lowers at unexpected times.

A bit of information on the history of water power…
The biggest water power dam is 400 meters from the Niagara Falls
The first power plant was made in 1882.

I like the way you write very informative paragraph and short paragraph. I agree with the fact that the many fish gets killed by the turbine.So do people stay near a dam?

I agree because you did explain the Consequences of the use of Hydroelectric power. I also Disagree because on your 3rd paragraph. "According to the world there are many different consequensces. Some like there is no pollution." If there is no polluton isn't that a good thing and not a consequense?

I did not know that fish are killed trying to get through the turbines.
I have a question can the fish escape sometimes?

I really like the way you kept your paragraphs short but still informitive. Starting eith the question was also very helpful because you knew what you were getting the answer to. Nice Job!!

I like the way you you summerized your paragraphs giving just the right amount of information. Has the dam flooded? How did the people survive?

Hi, Alea. Mom here. I liked our conversation at home about the fish ladder. I had never heard of those. I think it is a great idea to build a way for fish to swim/migrate around a dam so they can still get to where they need to be. I wonder about the water temperature, though. If the turbines make the water hot, does it hurt the fish? I know fish are cold-blooded and can change temperature with the water, but I suppose there is a limit to how hot anything can get!!!! Love you - M

Alea,

Thanks for the dam information. What types of hydroelectric power are there that don't use dams?

Love,
Uncle Rob
