DAM
On the one year anniversary of your infamous joke, and, in leu of a "thumbs up"....I will take the opportunity to say thank you for the much needed comedic aside.
What did the Beaver say when he saw the river?
Dam It!
Walk yourself out please...
Three years later, I am still rolling on the floor with laughter!
Good one
Please... Dont touch our Dams
Greetings from the Netherlands
TheBigpippo I got a bomb and lots of time.
Murica...
Fasken2 Then you got lots of time to figure out how to destroy a shitload of dams with only one bomb xD Also greetings from the Netherlands
O really?
Citedspy HD Maybe it's a big bomb?
You seem to forgot that dams are not built just for energy production, instead most dams are build to store water. If it wasn't for dams there would not be enough water to irrigate the agricultural fields and major cities in regions without large sources of water that run all year long, remember that some river dry-out during the summer.
what would be of Las Vegas without Hoover dam?
That is why you dont live in desert.
In my point of view dams are good in dry areas, to store flood waters and use it gradually, and making dams in somewhere which are green naturally is not good enough, instead it is better build canals to transfer water to dry lands
@@mostafajan7025
In some areas you need both, canals and dams. Some canals (and pipelines) carry water for hundreds of km between an artificial lake created by a dam and the dry areas that need water and where there are no rivers only small creeks.
@@pedrolopes3542 yeah that is also good point
You've actually inadvertently tapped into an even bigger picture issue! The issue isn't just dams but why we even need huge stores of water in the first place. The agricultural practices we have today are incredibly unsustainable, giving rise to the need for harmful structures such as dams and practices such as depleting groundwater faster than it can naturally refill. The problem is not that there isn't enough water due to natural reasons but that our food industrial complex is designed with profit as its paramount goal and with no regard for the natural balance of ecosystems or future generations. Food and human life systems CAN be designed to support modern populations but NOT the modern wasteful way of life we have come to accept as normal.
I love how anti hydroelectricity point out all these cons, while pretending that wave, wind & other technologies currently are viable alternatives.
First, as you pointed out, trying to store wind energy requires consumption of fossil energies (natural gas). Then, we have to deal with the cost, materials & energy (likely fossil) needed of creating the infrastructure for storing that energy.
Next, wave power has such low energy output per area, that it would require utilization of vast coastal areas & bays before one could generate comparable energy as a single hydroelectric power station. That also ignores the difference in cost, material & energy needs.
nuclear
Yeah, everything has a downside. Let’s start replacing fossil fuels instead of talking about useless negatives.
@@idanofek9314 "useless negatives" you types are exactly the problem. These negatives need to be ironed out, systems replaced, new ideas thought of before we put all of ourselves into debt and ruination. California killed all their nuke plants, stopped using fossil power, tried to shift to wind and they've absolutely devastated their power grid, and their forests are burning.
Void of Space and Time no, it should be companies who do it. I think we should fund or lower tax on companies that emit the least greenhouse gasses per energy unit and do the opposite on companies which emit the most green house gasses. The companies that emit the most greenhouse gasses per energy unit will get worse taxes and regulations until eventually, we will abandon fossil fuels. The way I phrased my idea is very simple, the government needs to create a good plan for what companies are the worst for the environment and which ones are we gonna tax the most or least. This will create competition which creates innovation.
Even if all those alternatives are not perfect, they are still better than what we have now(fossil fuels). We can’t rely only on innovation, we have to start replacing them so that we have more time to innovate and before the point of no return.
@@idanofek9314 Many governments are already doing all this and it's not enough. These are megaprojects. The money comes from people's tax money and is not infinite.
This video only shows the cons of water dams and hydroelectric powerplants and delivers alternatives that are not as stabile as coal and hydropower, wich are used to produce peak energy during the day. Also now we have new tehnologies, wich can ensure the migration of fish, the transport of sediments, etc. So, from the impact on the eviorment view, you can not throw all the big dams and hydropower plants in the same basket as the smaller ones. The big power plants like the Hoover, Itaipu etc. have a big and negative impact on the eviorment, but the smaller ones (less then 100MW) now have or can have a positive impact. This video doesn't objective, accurate, nither checked deliver information about the issue.
Yes, very biased video. Why you compare a lake to the emissions of a fossils-fuel plant that's misleading because it's a one-time emission. Also, didn't mention a single benefit of dams.
+Mark Brand
That's a very simplistic view you're taking, and you're implying that CO2 is the only ecological issue worth worrying about. it isn't; it's not even on my "top 5." Give me MORE WILD LAND, even if some of it is warmer and drier than I'd prefer, than spend all our time fighting the inevitable W/R/T CO2.
I'm simply refuting his claim about gases released. Hydroelectric energy would have been replaced with coal if it didn't exist.
I know there are other negative affects, most things are a two-edged sword.
I used to watch a lot of video's about dams and there are many ways to counteract the negative impact. He didn't mention any of them.
Nuclear energy is BY FAR the safest, cleanest, and most productive source of energy.
We should stop making more humans.

Costa Rica makes around 80% of it's energy from hydroelectric plants.
I saw what you were saying, in 2016 about 80% was made by hydroelectric power.
*Update* I saw something saying in 2019 saying only about 70% was made by hydroelectric power but 99% of the country's electricity was made by renewables as a whole including (in order from largest percentage to least percentage) hydro, wind, geothermal, biomass, and solar.
@@benjaminfisher1565 Yes! I think we actually managed to run on 100% renewable energy for like 200 days in a row due to the favourable rainy season and winds. And the government is trying to expand renewable energy production in other areas other than hydroelectric in order to diversify the different energy sources.
Wrote a nice paper on the pros and cons of Hydroelectric power for my energy class last semester. It sounds good on paper but the actual repercussions are quite substantial. Thanks D News for this interesting video.
Hi can I get that paper
Dams are also used to store excess energy. Electric pumps turn to pump water back up to the reservoir which can then be used to spin the turbines when peak demand comes in.
Please help me to answer the following question:
what are the distruction phase effects of the hydroelectric power plant on the environment?
We should build more canals to redirect rivers and their water to where we need them and control flooding. Dams are far too damaging to river ecosystems.
''I am your dam guide. Take aaall the dam pictures you want, now are there any dam questions?"
''Yeah, where can I get some dam bait?"
You guys should put the annotated video in the description too, that would make it a lot easier for us on mobile, since we don't have annotations yet.
Could you guys do a video on Trompe air-compressor technology? It seems like a promising alternative energy source.
you forgot to mention some pros like supressing floods and irrigation.
Is there a way to harness hydro-electricity using ocean's current instead?
I love that you name your sources of info and stats.
A question for the engineers here: What about small dams with no Reservoirs?
we have those in Bhutan, they are called 'run of river dams' they do not have reservoirs. The problem is during low season we have to import electricity
I’m a hydro engineer in New Zealand. We have a lot of hydro here, and lots of them are exactly that. They tend to do much less ‘harm’ to the environment when built but also have no storage, so can’t help with floods etc. plus can’t act as a battery.
Hey DNews I've got a question.
Is it possible to lose electricity?
so, in norway some dams have smaller 'salmon stairs' somewhere on them which allow fish to climb up and get to the taller water source, I assume those help the problems with hydropower quite a bit
We're starting to build tidal lagoons here in Wales.
Brilliant. Thanks for this video. People are generally ignorant of any cons of hydro power.
What is the alternative for the large scale food control then???
Wow Trace you're on fire! Great vids lately!
Thanks! :)
Don't listen to the hate ..........
CRAFT !
Trace Dominguez Dude, we need more Dams in California to save the water from the rivers for future uses (b/c of the drought).
Just build perforated dams( a dam with an open bottom section for sedemint and fish to flow through under the dam … you build a dam wall low enough to protect from major floods and to generate electricity when basins is topped up but high enough so that a constant amount of flowing water/fish/sedemint can pass underneath undeterred
Nice clip. (4:34) I like how young Trace looked back then.
Trace, you are an excellent entertainer/educator.
you can filter coal into an algae tube to capture the emissions and then burn the algae way better than hydro
Put turbines in already flowing water/ falls or create elevations . That's what we do I'm QUEBEC we are almost 💯 % Hydroelectric powered. No nukes in here.
Algea rotting emit hydrogen sulfite a toxic gaz . Burning 🔥 it would polute the air but would be smarter than coal with the sargassum crisis in the Atlantic Caribbean/ Mexico coast. I believe BP spill didn't help .
Ok, where are you gonna get you precious non polluting electricity. I would love to work on a damn dam where do I sign up. Ok I bet it, but really, how much vegitation really builds up inside the dam resivore, in that it decomposes to methane, crazy...
What if you had a giant waterwheel spanning the entire river? Multiple ones... They don't dam the river up. Minimal impact on local wild life... I would think they would not generate as much power possibly... with it not being falling water, but just water moving at 3mph or what have you... but if it saves the environment? One that spanned even a small river would still be quite a bit of force...
Nobody:
Dutch people: guess I’m going to drown now
Why no mention to the recent findings that pouring salt water over graphene produces an electric current when mentioning alternatives at the end. It's super cool!!
Perhaps it would be a good topic for another video.
Tesla's batteries + solar power.
Not enough batteries in the world for everyone you know :/ Hell we can't even feed the whole damn population let alone create ridiculously expensive batteries and panels for everyone .
HomeSkillenSLICE Tesla's batteries are cheap. We can't feed the population for many reasons unrelated and related reasons.
It's barely enough for 1 house and car and a bit of heating in the winter.
And even if efficiency goes up, that's just residential power in detached homes. (what about apartments)
what do u think batteries are made from? they dont grow on trees
Only 3%? What a waste! That actually makes me quite angry.
Agreed, Delaware is small but more than twice as big as you think.
I've heard that in the event of a catastrophic event, like a nuclear war, the hoover dam could be the last source of electricity in the US. From what I've heard, it's designed to run by itself, and could run for about 20 years without human intervention.
No dam can survive without human intervention. They need daily maintenance or they start to deteriorate.
Not likely, given that the hoover dam is only going to be viable for a few more decades, it's reservoir is drying up rapidly due to climate change
Seeker: STOP MAKE DAM HYDROPOWER CLEAN ENERGY AND USE THAT DAMN BLACK COAL!!
Damn excellent video!
Results in DAMN cold water =D
Trace Dominguez Will you be doing any space videos that talk about space colonization on Mars, Venus, Callisto, And Titan? And could you guys at DNews do more videos about space and space travel please?
Great video DNews!
We also make news videos on our channel and other videos like challenges and vlogs. We're starting a podcast soon too!
Beavis: "Yeah, I just have a question. Is this a God damn?"
Yeah no one gives a dam! Haha you get it? Damn I'm lonely.
Ico Petrov did you mean dam i'm lonely?
jesse scheepmaker haha yes!
Ico Petrov Dammed emotions. :^(
Ico Petrov Do you need a hug?
Ico Petrov I didn't get it at first, sometimes I read the comments of the video before reading the title.
Do we just need better energy storage?
Another dam good video. As a Canadian who gets all of his electricity from hydroelectricity I have to say I don't give a dam! It works great and once it's built its basically ever lasting.
Oh ya everlasting excluding the constant maintenance and repairs.
Nahele Duskwalker hydro electrecity is the most and cleanest energy source we have yet.
We should stop burning coal before stopping building dams.
Horray for environmental superiority :D BC resident in surrey here, hydro rules.
*"Jean-Francois Prince"*
Dams make sense in wet climates but were the worst thing imaginable for the riparian ecology of the desert southwestern USA. By allowing people to build cities where cities have no goddamn business being [Las Vegas], you accelerate the desertification of the area. Plus the loss of scenic and ecologically diverse Canyonlands...if anyone OTHER than Theo Roosevelt had been president, the Grand Canyon would be submerged!
Global Warming _threatens_ to make the world hot and dry, at some point in the future; dams (in the wrong place) do that, TODAY. I'd sooner let the Colorado run free, and deal with the incremental warming of coal power, than utilizing the Glen Canyon and Hoover dams.
dams are not ever lasting
dams are getting bigger all the time "dammit" LOL first dry joke witch actually made me giggle xD
Great video! Very helpful for a debate in doing on the topic 👍
Rather than just building standard dams...use them to create electricity. Makes more sense than just holding back water. Convert current ones to produce power as well..
What about small-scale hydropower?
The puns at the beginning reminded me of Percy Jackson
Same especially Hoover Dam!
in the bohol Philippines my friend told me he only had 1 earthquake he encountered in his hometown because there's no dams
Rivers was to kept flowing and regulate heat and cleansing the environment prevent draught or flooding
still better then gas or coal plants, and nuclear plants have the states breathing down your neck, solar doesnt work at night and wind isn't reliable enough to be used for 100% of power. what do you suggest?
Rhavi Marques Wind is reliable enough,5% of the Dutch power usage is windenergy. Most of our energy these days is actually green energy about 30%. Also windmilles produce about 30% of the energy used in Flevoland one of our biggest provinces.
EDIT:
May I add that we only started building the main bulk of our windmilles in 2013 and were still building/making plans for new ones now
Rhavi Marques A combination of many.
Solar + battery + wind + hemp biofuel.
GT6SuzukaTimeTrials The prices would be prohibitive.
Hydroelectricity is the cleanest one.
Wind turbine, solar panel and battery all have natural impact, it is only because we don't know them well for now.
+TheBigpippo Wind turbines will sometimes not turn even when it is windy. If it is too windy, wind turbines will be destroyed.
Wow, Trace, you looked young back then =)
The title should be why we should improve our dams. What materials we should be using. What we should do with the stagnant water.
QUEBEC 🇨🇦 CANADA has a geographic funnel on top of the AMERICAN continent. Water flows naturally all year round & Even more in spring Just like Niagara Falls . You just put a Turbine in it & in rivers . It's Cheap, it's Green it's smart
Ironically I bet this video was filmed in NYC which gets a lot of its electricity from 0 carbon Canadian hydro! With proper planning (which Canada has) almost all of the ecological risks can be mitigated.
we in Norway gets 99,9% of our power from hydropower
Robin Kristiansen are there any problems with it as presented here?
***** i haven't noticed any problems
Robin Kristiansen Do you have this salmon going up rivers and have to deal with it in Norway is there no problems for fish?
***** i don't think there is problems
Robin Kristiansen Well good for you. You have hydro and oil and can put solar panels on top of that as everyone else. Electric cars should do well in Norway if energy is cheap.
Wish this video addressed what's going on with the other 97% of dams
Because dams can slow it down or halt the rotation of the earth (if it’s too many of it).
Canals beats dam since it has holes for path so water can go through
Yes, we could store the wind. We could also use the wind during peak times to charge batteries which we could then use for power during off hours. It's the same with any source of power.
a dam can store water and energy. There are high and low rainy seasons. Many dams are a reservoir for cities and farms as well
Referring to what do we do when the wind stops blowing, that's were energy storage will be a game changer. I look forward to having a Tesla Powerwall in my garage storing the energy generated from my solar panels for the night.
Plus they create sub-climate conditions in surrounding areas, therefore altering and creating weird weather conditions.
What about dams that are used as flood control?
So how bad are beaver dams then?
Video on effects of standardized testing?
At least some dams have a dam snack bar.
2:40 I would not call that white spray flying through the air "barely oxygenated"
The methane problem from submerged plants is a problem that is hardly talked about and yet about one quarter of all the greenhouse gases created since the anthropocene has been caused by rice agriculture and the submerging of rice plants. We need to create better yielding forms of upland rice that can be grown dry soil and replace rice with other high nutrition crops like peanuts and corn. While corn is water intensive it is also the most nutritious of grains so rotating between peanuts and corn using terraced farmer techniques like the Maya where you surround a dirt palisade of terra preta soil with diverted water would allow you to grow lowland irrigated rice along with corn and peanuts while utilizing less water and fertilizer. Maybe you could float this idea on your channel Trace. I think it has been tried to some extent in South Korea.
We need to build more dams. They help us to not use fossil fuels to make electricity.
Okay, why is there pixelating going on for UA-cam videos all of a sudden? I've done my updates to stupid Windows 8.1 recently and UA-cam has updated to mostly fully HD now, but what the hell? I can't watch a video without it pixelating like mad. What's going on?
Why aren't different types of generators being designed that work without the dam? If we can use wave power, why couldn't we use the power of flowing water from rivers? Sure, it won't be as powerful for a given area as a dam but you can distribute the devices the entire length of the river, hopefully without causing damage to the fish population or the flow of nutrients.
Yay! Delaware gets a shoutout! The first time anyone who ever existed acknowledged our existence too!
Brazil's... and Paraguay's* Itaipu.
Annotations don't work on phones so I can't watch the windturbine video.
Obviously, i do not know anything about how dams, nor water turbines work, but why not use flowing water to generate electricity, just as the old mills, in stead of having to create huge dams?
All ways to produce energy have environmental impact. To produce solar pannels is necesary to extract extrange and hazard minnerals from mining, Wind energy kills birds, and both need bateries which have very contaminant chemicals. Coal and hydrocarbons produce greenhouse gasses. At the end Hydropower is the best. Yo can create multipurpose reservoirs to store water wish allow to supply water for cities, control flooding, and you can produce fish in the reservoirs. The new standards of desing of hydropower plants that take in count all the environemntal concerns. I am sure the water you drink came from a reservoir. Your city and your food is feaseble because of them too.
Why do dams release water in times of flood?
WOW, Old Trace looks young. Paradox?
solution: thorium reactors + population reproduction rate reduction + steady state economy instead of growth based
I could not say anything before thanking Trace and collaborators for sharing with us this very informative video which I wished it was not so biased, given the power to influence audiences, and the bigger responsibility in doing so........ we see today's bent manipulation coming from anyone with an audience but certainly towards a more enlightening outcome days ahead.....ignorance can be improved while stupidity should not ..... dams are also natural happenings, also done by other animals, water reservoirs are absolutely more life givers than not, humanity would certainly be different if water was only frozen or in the skies.....without oceans and lakes, natural or man made as the bigger of all dams life would be terribly different. Agree? Data, like a picture or many moving pictures is not the same for everyone watching.... make another one more just.
What about for drought prone areas. Dams store enough water to last through the dry seasons.
+Rohan Thatté With extended basin area evaporation is more rapid. So you get less water to begin with due to drought+evaporation and dams get almost closed with very minimal flow until the neccessary water lvl is achieved. But what happens downstream meanwhile? Well what once was a river is now a creek with dead fish and plants laying in its banks. No beauty, no life, no fishing, swimming or boating. And if you thought of benefits using dam water for irrigation, well that is just dumb. Look what happened to Aral sea for example. Your logic is so flawed it makes me scared people like you make decisions for making damn dams.
I live next to small river and we have plenty of water North, but during summer river almost dies due to dam. It`s really sad.
+Reinis Miks oh in no way was that an argumentative comment. I was actually asking. Ive just moved to India, to a city on the Deccan plateau. There are monsoon rains for about 2-3 months from June and practically zero precipitation for the rest of the year. It cools down to about 13-16 degrees Celsius from December to end of January. Then onwards there is pure heat of 40-44 degrees Celsius until the following monsoons in June.
Yes cities are growing, industry is growing and still 70 percent of the population is agriculture. From what I know, there are specific dams here to store water for specific uses, one that goes to a municipal water purification plant for drinking water, others for agriculture, manufacturing industry, hydro-power.
The water crisis last few years have been so bad that there is a specific fresh water in the kitchen that only run for 4 hours in the morning and whatever gets stored in tanks would be used for other taps around the house.
So, that's my question.
Rohan Thatté
Oh, sorries. Yeah storing excess rainwater is not that bad. I was reffering to arid areas, like California and similar climate zones, which are considered arid.
+Reinis Miks yeah that's alright. There are idiots online that argue for the sake of argument.
Yeah California has had some rough couple of years. Reminds me of one of those videos that went viral of a trucks unloading millions of black balls into reservoirs to stop it from evaporating.
There are methods and regulations used all over the world to ensure that the flow downstream a dam is enough to ensure the maintenance of aquatic life and shore ecosystems. There is no country with a minimum of environmental law that would allow to entirely cut river flow after the construction of a dam. Regarding only the maintenance of life downstream a dam can have a positive effect regulating flow and keeping a minimum of it even during long droughts which would be impossible without its construction.
Regarding evaporation this argument is silly, evaporated water does not simply disappear. We live in a closed system called planet Earth... The water evaporated in a dam reservoir would just be evapotranspirated by local vegetation systems and natural reservoirs or from the soil. Also, local temperatures often drop because of constructed reservoirs. There is no decrease in net water availability when considering the regional scale. If that would happen the dam would fill less and less every year which is just not what happens.
Regarding the other activities (swimming, boating and fishing) some of the uses for dams are exactly recreation, navigation and the improvement of fisheries. Badly design dams can be detrimental, of course, but a badly designed anything is not good.
Regarding irrigation, water resources surely are strained in several places due to it but this is not the fault of a dam per se but of the demands that are unsustainable. In many places irrigation takes water from aquifers (wells) with cause the soil to sink by several meters.
There is form of energy that has zero impact on the environment but dam construction has come a long way to reduce those. This video say nothing about the forms to mitigate dam impacts (sediment discharges, fish passages...) or any serious alternative to producing reliable and steady energy. It's all fun talking about how we could do this, or could do that... but most "cleanish" alternatives are decades away. This video was very disappointing.
Dams surely aren't the future of energy but considering the alternatives clearly are not the worst we as a civilization could come up with.
Yeah, massive dams are complicated project because of all of what you explained. However, multiple small dams could be a better alternative. Hydroelectric power is still way better than thermal or gas plants, and also more efficient than ocean or wind electric power generation.
Still an abomination of nature not worth it. Robs estuaries of freshwater for greater productivity/ recreation value, fish spawning usually, alters weather probably to some degree, too much nutrient and sediment buildup in resovoirs, and so on
Not saying they cannot be enjoyed/ have benefits, but the pro's don't outweigh the cons, ultimately
No oxygen below dams?? Some of the best trout fishing in the world is below western dams.
We can use the tides. It's called Tidal Energy like wind turbines underwater. It's 90% efficient, and extremely predictable. Tides come in and out everyday, carrying megawatts of energy potential.
Should just stick with water wheel design. It's not as strong, but it won't totally fuck everything over.
How much energy can water wheels produce, and what are the harms of water wheels on the environment?
This is a good dam video. *ding ding ding, most original comment ever*
California's megadrought is caused by lack of reservoirs. Ecologists are good, in moderation.
loved this video
Dams have stars with water floing through so the fish can get up 🙀
I don't think the hardly oxygenated water will be bad if it goes down a dam and gets oxygenated if you know what I mean.
Yes and because youre somebody who has probably never even thought about this before, your off the cuff hypothesis is clearly more accurate and useful than that on an actual expert
My refutation: Miami Conservency district.
You are excused.
I can't believe there actually is a group called the "Union of Concerned Scientists". What a World we live in...
What about the hydroelectric ones
Solar panels and wind power are limited from weather. In Winter, solar panels doesn't work, Sun is very little. In summer, wind power doesn't work, wind is very little. It's relationship with season in solar panels and wind power
huh? wait... when did D-News start making interesting videos again? :)
Except wind turbines kill bats or so I've heard. Poor bats.
You live in Southern California or Nevada or Arizona thank the Hoover Dam none of them would be able to support their current population levels without it
William Sonak Yes, and the whole reason California is in a drought is because of ecologists banning dams.
Bruce Dobson Or you know the whole La Niña climate pattern thats been present for the last couple of years, that's why here in Australia theres been record floods and rainfall. The effect is supposed to cycle through this year into an El Niño, effectively reversing the weather on either side of the Pacific, so wetter in the Americas and drought conditions here
Huy Ly It's been 8 years of drought, much longer than any Nina/Nino cycle. It's climate change.
TheJerbol Your right it is climate change, climate change makes weather patterns more extreme, it aggravates the ENSO effect on both sides of the Pacific. Also the last El Niño was about a decade long too, most of our dams here inland dried up completely (
That's a "con," not a "pro." Dams let cities exist where cities have no goddamn business being.
Where's the dam bathroom?
