HOW HYDROELECTRIC POWER WORKS:
From the dam's reservoir, water is directed in pipes called penstocks through turbines. The falling water spins the blades of the turbines, which are connected to generators. There are three types of hydropower facilities - impoundment, diversion, and pumped storage.

Impoundment - uses dams/waterfalls.
Diversion - divert a portion of a river through a turbine.
Pumped storage - when the demand for electricity is low, a pumped storage facility is often used to pump water from a lower reservoir to an upper reservoir. when electrical demand increases, the water is released back into the lower reservoir, passing through a turbine to generate electricity. the same water is reused many times over.

PROS OF HYDROELECTRIC POWER:
- Most obvious pro: renewable energy resource. Can use sea water - infinite source.
- Power dams generate enough electricity to repay the cost of construction, so they do not exhaust the economy/are an affordable source of energy. Very low operating cost and highly automated.
- Water can be recycled and run through the turbines numerous times.
- Humans can control the source/amount of water - not unreliable, like wind, sun, etc. Power is available on demand.
- Can use falling water that occurs naturally - for example, waterfalls. Therefore, there is no need to build an above-ground plant, only underground generator system. Does not ruin beauty of the waterfall - Niagra Falls is utilized for hydroelectric power and vistors cannot see any of the mechanisms.
- Does not contaminate or pollute water. Water is so clean that reservoirs can also offer a variety of recreational opportunities, including fishing, boating, and swimming.
- Emits extremely small amount of greenhouse gases compared to fossil fuels.
- Hydroelectirc power has received green power certification as issued by the Low Impact Hydropower Institute. Each facility must pass a series of rigorous tests to make sure the CO2 is minimal

CONS OF HYDROELECTRIC POWER:
- Dams can block fish passage to spawning grounds or to the ocean.
* Counter arguement: Many plants now have measures in place to help reduce the impact on fish spawning, creating separate passage ways for fish to pass through.
- The diversion of water can impact stream flow, or even cause a river channel to dry out, degrading both aquatic and streamside habitats.
* Counter arguement: Diversion facilities are becoming less and less common as Impoundment facilities, which have no negative effect on the landscape, are becoming more common. Additionally, the amount of water diverted is hardly ever enough to dry a river. The amount of power does not depend of the amount of water but on the height the water enters the turbine from.
- Impact on water quality by lowering the amount of dissolved oxygen in the water.
* Counter arguement: Many plants are taking measures to add oxygen back into the water before the water leaves the facility.

Hydroelectric is not an effective way to produce energy

i stand by my above resolution

Hydroelectric dams are expensive to run, and build such dams as the hoover costed over 2 million dollars.

To support a dam you have to have a constant running rivers, most running rivers now days are big tourist atractons and their is almost nowhere to build them, dams are ugly giant things that kill fish, and stop water flow.

another argument i make is that dams polute the water so it is not drinkable to anybody from the turbines that spin. and chemicals have to be used to clean the water, theese chemicals have been known to cause deadly diseases

Hydroelectric dams are not expensive if you consider the sustainability. The only thing expensive about them is the initial payment. They produce as much electricity as other conventional sources without the greenhouse gas emissions at a much cheaper rate per watt.

> "To support a dam you have to have a constant running rivers, most running rivers now days are big tourist atractons and their is almost nowhere to build them, dams are ugly giant things that kill fish, and stop water flow." <

I'm not sure this sentence is logically comprehensible, but as I said: Hydroelectricity dams have separate passageways for fish. Even if a few fish die, so what?, there is no shortage or endangerment of them.

As for the tourist attractions; most plants hide there structural turbines and so forth. Once again, if you happen to see a metal blade sticking out of the water, so what?

No dams today pollute their water with chemicals that produce "deadly diseases".

In conclusion, seeing some infrastructure in the water or seeing some fish die, is definitely not a reason to be against hydroelectricity. Hydroelectricity is sustainable, cheap, and effective.

My Opponent still stands by the resolution Hydroelectric power is an effective way to produce energy.

I am still oposing this topic,

My opponent stands by the fact they only kill a few fish.

dams kill about 80% of the fish. Science shows us that the dams – not over fishing – is the biggest reason for the declining salmon and steelhead runs.

First of all you are not debating my whole case. You are only picking one section of it, upon which you can try counter. The others - well lets assume you can't debate them and agree.

So back to the fish -

Sierra Club is one of the oldest and most radical environmental groups out there. I hope you know, statists can be manipulated very much to suite the intended need. The statistics of sierra club are grotesque, and the dams mentioned surely don't equate to the overall production of hydroelectricity - just a few dams.

As I said, the loss of a few fish enable us to cut carbon emission to nearly zero percent.

On a side note*

If you view my opponents comments in the "discussion section", he is obviously not very articulate, but in fact rude, and disrespectful. It is also obvious he has no idea what he is talking about.

Any one can argue that the source can be bad. thats not a valid argument

I do not have to argue your whole argument, as for you never said this in your resolution. and also you say that i dont answer your whole case when you are the affirmative and i am the negative you have failed to answer any of my arguments in my last speech, the only thing the aff does is comment on my rude comment and say how my sources are unreliable and question my grammer this is not an answer to my negative case.

My argument is not worth the amount of problems it creates, major money damages and such from the following sources. then i argue that your evidence is unreliable and should not be accepted.

A month long fish kill at Bagnell Dam on the Lake of the Ozarks killed more than 43,000 fish with an estimated value of $3.2 million, shows a report by the Missouri Department of Conservation (MDC).

"This fish kill will have a serious, long term effect on the paddlefish population," said Turner. "It will take many years to restore the large number of fish killed over the last few weeks."

It looks like the only way to save the Snake River salmon and to improve water quality is to punch holes in four dams and let the river flow free, the U.S. Environmental Protection Agency said this week.
http://seattlepi.nwsource.com...

and from the survey
http://wis.dm...
83% agree with me on my case

And from my tourist case earlier i will explain this now

One of the main rives that go into the grand canyon was recently damed, and undamed because people had been complaining that the water level has decreased. they undamed the river for this reason wasting 21 million dollars

Unless the aff can argue all my points, vote neg

how can anyone be con on this...he simply states his points with supporting information...his points are very true...i saw most of his points when the History Channel did a show over this issue...past issues are a small issue, but as a country we need to update many dams to current standards (artifical rapids for spawning fish) this would cost money, but as stated before the investment is more than worth it. the topic was do the pro's outweight the con's and they do.

I do not understand how the voting has turned in my opponents tide. Clearly, he has no knowledge of hydro-power and the enormous benefits it has bestowed upon mankind.

the con person here has NO CLUE

Hydro is the best and cheapest form of energy and its totallu environmentally friendly

One of our clients, San Joaquin Irrigation District, gets 50 MILLION a year in FREE MONEY from their dam, and they can seel the power when they want, in peak summer at the MOST expensive times

problem : we cant build any more dams becuase of the libs
