Q: hydroelectric?
ok im like realy bad at research… so if you could give me some info on hydroelectric… or maybe give me a good website that will… thanks!
A: hydroelectric is electicity generated using water.
wikipedia is always a good source for helping with anything like this:

Q: What is the difference between hydroelectric power and hydroelectric energy?
I’m writing a paper on hydroelectric power and I keep getting other stuff about hydroelectric energy too, and I can’t figure out if there’s a difference. Thanks!
A: The same, for your purposes.
Q: How many megawatts would a hydroelectric plant in Cincinnati generate? Enough to power the whole city?
I’m trying to do an economics project were we are each given an alternative energy source to research. My groups project is Hydroelectric power, my job is to find out if we installed one of these plants on the Ohio River if it would produce enough energy to power the City.
A: well it depends on how big the city is, how power hungry each home is, and how much stored energy you have in the river.
Hydroelectric plants store the energy in a reservoir and drop the water down a Dam and through a fan blade which is conected to a generator. The MW generated depends on the flow of the water and how much water you have at the top.
A typical 5 MW hydro plant would have enough power to generate electricity for about 1500 homes
Q: How do solar plants and hydroelectric dams generate electricity?
Can anyone explain to me in a simple way how solar plants and hydroelectric plants generate electricity? I’ve done research, but I’m a little confused.
Please note, I am not asking how solar panels work. I want to know how solar PLANTS generate electricity.
A: if you are talking about dams, than water passes through turbines which is basically a big underwater fan. as the water passes across the blades it makes it spin. the turbine is connected to a generator which makes electricity.
Solar plants. if your referring to oraganisms i cant help but a plant that doesnt use solar panels probably uses mirrors that are pointed at central point, usually a tower. All this light shines on the tower heating water until it boils. The hot, pressurized steam rushes over a turbine just as at the dam, and that runs a generator to make electricity.
Q: How to build a dam for hydroelectric power?
I have a small creek in my back yard.
Thinking about building a dam and a small hydroelectric power station.
How do I do this? Are there any legal issues I need to know?
A: A small water turbine is ideal for creeks . Something like this to experiment with would be a good starter for you http://www.energyquest.ca.gov/projects/waterenergy.html .
You don’t really need a damn just a hose leading up stream reduced smaller as you come down stream . This will create a good hydraulic system and safe for the wild life
Q: What are some futuristic uses of hydroelectric power?
I know that we use it now for powering homes, factories, etc. And I know that we will probably use it even more in the future. But I am wondering if there are any cool, unique, and specific concept designs (things thats people have already thought of and I can find information on) i.e. a hydroelectric car or a hydroelectric house.
A: There has been some talk about designing turbines for underwater use, that are turned by ocean currents and tides. There are some pretty steady currents available, but there are some big hurdles involved too.
Q: How does a small hydroelectric generator work?
Im doing a school project and i need to know how a hydroelectric generator runs for house use only not a dam or any other big one just one that is used to power a house
A: Same as a large one, but on a smaller scale.
You still need moving or falling water as a source of mechanical energy
to drive your generator.
For a small residential sized installation it would probably make sense to generate D.C. at a constant low level and store it in a battery inverter
system to handle the variable loads that such an application demands,
rather than build a big plant capable of handling the peak draws which
would be idling most of the time.
Q: What are some ways that hydroelectric energy can benefit the environment?
Guys I need help with my science paper about what is the best source of renewable energy. I need to know lots of facts on Hydroelectric energy A.S.A.P. please this paper is due today!!!
A: It generates no greenhouse gasses or any other pollutants.
It is infinitely renewable, as there will always be rivers. (This also means you don’t have to buy fuel for it).
Best of all: it is not intermittent, meaning it is always available, day and night 24/7. Wind and solar do not have this advantage, since they only work when the wind is blowing and the sun is shining, respectively.
Those are pretty much the three best things about it.
If you want some cons for it, those would include disruption of ecosystems (many animals depend on an interrupted flow), the fact that it is only available in a few specific locations (most places don’t have giant rivers nearby), and the slight safety risk (the dam could break and a wall of water could flood the shores downstream).

Q: Do you think that hydroelectric energy is a reliable energy resource for a safe and clean environment?
Ok! Hi. I have a research paper for English, and my topic is hydroelectric energy. I am having a hard time deciding whether or no hydroelectric energy is a reliable enregy resource for a safe and clean environment. To check it up, go t Wikipedia.I need help! 
Thx
A: No. In the state of California, our new policy (AB32) states that a big hydroelectric is no longer considered a renewable resource. Small dams are still considered renewable, but it is in our last of renewable priority. This is because of:
(1) Fish, like salmon, can’t travel upstream to mate
(2) Culture, some indian tribes are against moving a whole river!
(3) Towns, moving a river’s path can affect the economy and well-being of the towns that use the river
(4) Chances of it breaking, causes devastating effects (like China and their floods every 3 years kills millions of people)
(5) Damage to land
(6) methane emissions from rotting vegetation that becomes submerged
(7) Eventual silting
Q: Would hydroelectric power using the ocean and deserts below sea level work?
The Dead Sea, Death Valley, and various other places are below sea level and no more than a few hundred miles from the ocean. Would it work to build very large pipelines from the ocean to these places and then generate hydroelectric power from the water flowing from the ocean to these places? Obviously, we would have to regulate the rate of water flow to avoid flooding the destination to too great a depth, but if we balanced the water flow rate with the rate of evaporation at the destination, then the amount of water there would not increase. Death Valley seems like a particular good location for this, because it is very hot, so the water would evaporate quickly, and it is almost completely unpopulated, so evacuating the area that would have to be flooded should be much simpler than for hydroelectric projects in more densely populated areas.
linlyons and oil field trash are wrong.
The Jordan River has been flowing into the Dead Sea since Bibical times. The water level in the Dead Sea has not equalized with the ocean. It really does all evaporate. The water level in the Dead Sea is currently decreasing, because the evaporation is faster than the flow rate. The plan is to keep the flow rate low enough so that it remains below the evaporation rate.
A: Yes. The issue is efficiency!! Any time a weight is dropped work is released. Any time a weight is raised work is consumed. If more work is released than consumed the result is usable power. If you use x + y units of work to produce x units of power, you wasted energy. If you use x to produce x + y you gain energy. If you plant a seed and eat the plant you are more efficient than plant a seed, grow a plant, feed a cow, slaughter the cow, transport the beef, transport fuel to kitchen, cook the beef, eat the good parts of the beef. Wasted energy!
Q: What are the byproducts in the process of electricity production in a hydroelectric power plant?
For our field trip, we had to visit a dam that was the primary source of energy for a hydroelectric power plant. We also have to answer a bunch of questions, and one of them is this:
What are the byproducts in the process of electricity production?
I tried looking for it in the Internet, but apparently my research skills aren’t that great yet.
I appreciate it, thank you!
A: ozone and cold water.
the electrical generators have massive commutators, transformers and transmission equipment…all these produce ozone (not the same stuff in the upper atmosphere)
water is taken in from the botttom of the lake behind the dam…after power generation , it is let out downstream…..it is much colder than surface water.
Q: What are 10 pros and cons for hydroelectric energy?
I need it for a school project. I just need 10 pros and cons for hydroelectric energy only. Thanks!
A: PROS:
Dams can store rain water or water directly from the river itself. Then, in case of a Drought, the dam will still have a relatively constant supply of water.
Producing Power.
Controls flooding & provides recreational activities such as boating fishing and swimming, if the lake is not being used for drinking water (Dam Society).
Simple design makes for inexpensive repairs and maintenance costs (Dam Society).
Produce inexpensive (after completion) and clean power.
Renewable energy source, because the water is not destroyed by passing through the dam.
If needed, dams can be shut down instantly, where thermal plants take hours, and nuclear plants can take days! (Dam Society).
Very few breakdowns.
CONS:
Hydroelectric power production require flooding of entire valleys and scenic areas.
Disrupts natural seasonal changes in he river, and ecosystems can be destroyed.
Ends flooding that help to clean out the silt in rivers, causing them to clog (Energy Laboratory).
The silt that usually flows down to the Beaches and Estuaries is block by the dam.
Studies show that the plant decay caused downstream of major dams produces as many greenhouse gasses as more conventional methods of producing electricity.
Dams are expensive to build, and due to drought may become useless, or produce much less power than originally planned.
A dam being build in Quebec will end up flooding an area as large as Switzerland (Energy Laboratory).
Dams can break in a massive flash flood.
Q: How are fish impacted by a hydroelectric power plant?
I need to know how fish are impacted by hydroelectric power plants
also what are some ways that this problem is addressed in a hydroelectric plant?
A: Dams have reduced salmon populations by preventing access to spawning grounds upstream. To help, most dams in salmon habitat have fish ladders installed.
Q: Did you hear the government thinks hydroelectric dams are not green power?
Did you hear the government thinks hydroelectric dams are not green power?
90 percent of Washingtons Power is hydroelectric.
A: If by green, you mean does not hurt the environment, they are not.
Dams heat the water in the river, changing the environment for plants and fish.
but does that mean they can’t be improved.
Q: Where can I find information on Hydroelectric Power?
I’m doing a persuasive research paper on why Hydroelectric Power is a better energy resource than any other alternative resources. I have a few web sites I’ve found with good information but still need more because the paper is 8+ pages. I’ll probably check out a few books at the library as well but as far as at-home research goes…
What are some good, reliable web sites I can find information on Hydroelectric Power?
A: You might have some of these websites already…
