Here in Brazil, 65% of the electric power comes from hidro power and more than 80% from renewable sources. We have a long experience of building hidroplants, but the newer ones were built as run of rivers because of environmental concerns and are not as efficient as the storage plants. So, it’s important to find the middle ground between environment and efficiency, but personally I’m huge fan of hidropower.
@@quadq6598 The Chinese government may not care about the wellbeing of the country's population, especially NOT of certain ethnic minorities, but they do know how to plan for the future, and they are well aware of environmental issues that can make life impossible to the average citizen.
Hydropower combined with nuclear is great! Nuclear provides all the baseline power and hydro smooths any fluctuations. Once it's been constructed it's carbon free!
You'd think that the methane problem is solvable. It's pretty apparent that it's caused not exactly by the dam's reservoir killing off vast amounts of foliage, but that the reservoir is a permanent feature that eliminates seasonal ebb and flow of flooding, a natural way to rejuvenate the environment and soil. So, what is the solution? Agitate the water to ensure proper oxygen mixing? Periodically intentionally let the water levels drop? Something else?
I expect these dams are run as a commercial operation. Letting all the water run out would reduce the income available while the benefit would be to the climate not the company. Some kind of requirement or incentive would be needed to get them to do it.
In Germany, Hydropower isn't just forgotten but straight up terminated. It recently was classified as "non-renewable", so it loses many Privileges and hardcore Enviromentalists even want to shut down all Hydropower Plants.
@@ekowhanson9268 Natural gas can be made in a renewable way using organic matter. Germany is actually producing quite a lot of it (but Germany also uses a lot of coal...)
Hydro power is the most efficient renewable power. The efficiency of hydo turbines is often greater than 80% . however this depends on the torque of the water.
@@stickynorth Holland is a waterlogged country, constantly being drained for excess water that they pump into the ocean - I'm not sure they know how to farm in the desert. Or maybe they do - do you have a link?
We here in the Pacific Northwest get the majority of our electricity from hydropower. It's the best. We also have the Bonneville Power Administration which is a government agency that keeps the rates low and maintains thousands of miles of transmission lines.
I have often thought that flood waters could be used and pumped into drained aquifers in the Midwest. This would help many farmers whose water wells are drying up. And in turn help the entire country secure our food sources.
generally surfacewaters are not desired to be directly pumped into aquifers due to contamination risk... however a flood recharge where an area is purposefully flooded and allowed to trickle down (thereby getting filtered) is an option that is used in some areas.
That's actually a good idea. It'd probably need treatment and therefore more than just local, 10' x 10', pump houses. Our depleting aquifers are of grave importance though.
true california lets so much water go to waste when they need to improve infrastructure to collect it. they been using too much ground water. as dirty as it sounds imagine if urine was recycled and then used to hydrate californias forest. would prolly avoid using it for agriculture. but it is safe I mean NASA does it all the time.
I’ve considered that as well. In regards charging aquifers I heard the figure that 30% of the stored water in the Colorado River system leach’s into the sandstone. Was wondering where that ends up.
Pumped storage isn't perfect but for grid scale storage capacity without mining a small planet worth of lithium and cobalt, it's the best bet to make variable sources like solar and wind scale up

Environmentalists: --- everything is bad, Bad, BAD!! Thanks enviromentalists, for finding the negative in everything, for telling poor people they can't have the same lifestyle we enjoy, and doing this all while reaping the benefits of having grown up in a rich country. Hydropower is one of the cleanest and greenest sources of energy around!! Yet still, there are so many complaints about it. Ugh.
Pointing out issues isn't a bad thing. You need these problems to come to light to correct or mitigate them. We need to ensure that your not destroying the environment so all people, "poor" included, can enjoy it. You sound like a turn of a century industrialists who complains about not being able to dump chemicals into the river.
Yeah. The methane that would be POTENTIALLY released from a reservoir is miniscule and negligible compared to ALL the methane we realease. Also, rivers have been releasing this supposed methane for thousands of years. It's okay, woman. "But think about the poor fish, they won't be able to swim past the dam!!!" * Palmface *
@@rh5829 He has a point though. Every month that green energy projects are held up because they aren't *perfect*, is another month that we continue to burn coal and gas powering our electric grid.
As CA is finding out, you need water to make use of hydropower - but it does two things in one, holding water for use in a lake being even more important. Problem is you need to expend a tremendous amount of resources and energy to build a dam and powerplant, which can also take decades from start to finish. People poo-poo nuclear, but it is the easiest non polluting energy source that can be built almost anywhere; but it also takes a lot of energy and resources to build a plant.
California needs to delay closing Diablo Canyon and repair and restart the San Onofre Nuclear Generating Station. Grid operators are expecting a shortfall of 1.7 gigawatts in California this summer. San Onofre had a capacity of 2.2 gigawatts.
We need both hydro and nuclear, because nuclear has a constant output whereas sometimes we need more or less power. Hydro, whether pumped or not, is the best low carbon dispatchable generation. Use excess solar in the day and nuclear at night to pump up hydro then let it out at peak times and during the winter when solar produces less. They can all work together really well.
@@adrianthoroughgood1191 That's not exactly true. Nuclear plants can do load following, and be even quicker at it than CCGT. Hydro is the quickest one at it with both turbining and pumps, not accounting for batteries (which are very resource intensive). Thing with Nuclear is that load following with most reactor designs is a waste. Overall I agree with you. Nuclear for baseload (maybe a bit over minimum maximum demand), Solar for the increased demand during the day, I especially like rooftop solar and floating panels at Hydropower reservoirs (reduces evaporative losses and uses already built wiring to connect to the grid). And Hydro working as the balancer between all.
yep I served on nuclear powered submarines, never more than 600 feet from a running reactor core....longest I've been underwater is 87 days....it's a great source of power, compact footprint lots of power no pollution. :)
I was seriously expecting to hear about the potential of floating solar, and how that could eliminate the need for releasing water during the day. That would allow for *increased* hydropower generation during the night.
@@NVGEAR Floating solar would be cheaper, faster to build, would have minimal hookup costs because the dam already has a grid hookup, the panels would enjoy increased efficiency from the water and produce more power, the panels would last longer, the arrays can be rotated to track the sun, the arrays reduce evaporation, and the arrays would reduce sunlight making its way to the bottom, which would reduce biomass growth and reduce CH4 emissions from reservoirs. Why would they not invest in floating solar? There's no reason not to.
@@firefox39693 And you don't need to clear whole swathes of land to install the panels. There are Hydro reservoirs that are absolutely humongous. You wouldn't cover them whole, but covering like 50% in a well designed way would not have a big impact on the biomes. You could inject it into the grid, and do some PSH on top. But I bet you that operators would just use it all for pumping, and then release it during the dinner peaks.
@@AlldaylongRock Yes, you just pointed out that combining them, by using solar to pump into storage makes sense and increases simplicity by using a dedicated separate pumping system. Storage capacity can easily be accomplished by increasing the reservoir's volume.
As far as I'm concerned, hydropower is great, we should keep doing it, look for ways to make it better and so on, but it doesn't have the potential to supply much more energy than it is already supplying. Wind and solar, on the other hand, have huge potential to grow since we need a massive amount of renewable energy and they are the only sources that could meet the world's energy needs. So the headlines are deserved.
actually fam if as good as hydro is in generating power and regulating water flow to prevent floods. down side is water flow can become political and can damage eco systems that rely on water. look at how much water loss has occurred in the colorado river. with that being said Nuclear is the way to go with only biproduct of water vapor or steam and ofcourse the decay of radioactive material. however with regards to removing radioactive material we can just launch it to the moon through NASA's atermis program and spacex falcon heavy.
Yeah but we haft to dig for lithium for batterys and that releases a lot of carbon & U.S. uses African children to do the mining they often die & dont get paid enough
Indeed. Hydro development ought to involve protection of water catchment areas which produce the rivers that the reservoirs depend on. It can even be combined with environmental conservation efforts like afforestation, reforestation and agroforestry. Minihydro, microhydro and picohydro plants are also useful for small and off-grid areas. Tidal and wave energy also count as hydro.

I live in Wisconsin and many cities that are on a river have a power generating dam in the city (at least along the WI River). I think these dams could use some investment and be improved, but power producing dams are. Or overlooked. They are everywhere in WI.
But you have to look at the environmental impacts of these dams and what they do to the river ecosystems. Fish depend on getting from ace to place in these rivers and all a dam is, is a barrier to them.
Norway gets 99% of its energy from hydropower, the other 1% from wind and sun ... yes, they don't have any nuclear power plant, coal power plant or similar in the country, it's 100% running on green energy.

I love norway's electricity grid. It's a good help for the nations close to norway in the EU and the UK. It helps stabalize our supergrid a lot and i think that's super cool.
They also only have a population of 5.379 million in the Arctic where they don’t have drought to consider, I get what you’re saying but it doesn’t really apply to the 330 million Americans
Not only forgotten energy but forgotten free battery if you use a second flow management dam to allow the river flow to be maintained at a safe level while the turbine in the main dam is opened and closed based on the minute to minute power needs of the grid. Instead of dams producing power that is used to pump water uphill so you can get hydropower when you release it you simply close the dam gates until you actually need the power.
In Québec, the hydro power generation is dynamically adjusted. When wind/solar production goes up, they immediatly reduce flow of water through dams. This preserves the water in the reservoir and is far mreo efficient than letting it flow down and pump it back up. Hydro is our base load, we don't have nuclear or any sizeable fossil fuel production on the main grid. Where you have non-dymanic base load such as nuclear plants that take hours to adjust production instead of seconds, you can't do that and you end up with surpluses when wind/solar produce.
Depends on what environment level you care about - People really believe the world ends if you don´t fix global climate. Would you then care about local environment?
@@AERoVALKYRiEonce the dam has it's storage reservoir filled, it reaches steady state and no ongoing impact... Ethiopia has dammed up the Nile, and no famine or agriculture losses in Egypt. 🤷
In Nepal, almost 100% of the electricity comes from Hydropower but almost all of them are ROR & PROR types. But now storage types are also growing in number.
Dams in the US need to be rethought. We have minerals and fish migrations that are crucial to keeping plant life that in turn will help the water table hold water. These canyons have become deserts more since we have put the dams in place since nature can’t establish what it needs to create a healthy ecosystem
Here's my answer to hydropower: Lake Mead (which powers the Hoover dam and a huge part of 2 states and northern Mexico. Not to mention providing water to those same places - that can't be replaced) The combination of a changing climate and strong demand for the lake’s remaining water has resulted in a 100-foot drop in the reservoir since 2000. That’s just 10 percent under the lake’s high water mark in 1983, Lake Mead is shaped like a martini glass-wide at the top and narrows at the bottom. If the reservoir drops below 895 feet a possibility still years away Lake Mead would reach dead pool status, with potentially catastrophic consequences for millions of people across Arizona, California, Nevada, and parts of Mexico. Additionally, the power created by Hoover Dam is used to carry water up and across the Sierra Nevada Mountains on its way to supplying Southern California. So you see, hydropower is not flawless, and can go away when climate is unstable. Frankly, we need different sources of power, even fossil fuel power (for the immediate future) until we can reach carbon neutral (which we probably never will based on what I know about people).
Not a real major contributor in NV or AZ - Most goes to CA.... not sure any goes directly to MX per EIA stats... AZ - electricity by source in 2022, 99% of Arizona's total electricity net generation was provided from 6 sources: natural gas (42%); nuclear power (29%); coal (12%); solar energy (10%); hydroelectric power (5%): and wind (1%). Biomass, hydroelectric pumped storage, and petroleum, supplied the rest. NV in 2022, 99% of Arizona's total electricity net generation was provided from 6 sources: natural gas (42%); nuclear power (29%); coal (12%); solar energy (10%); hydroelectric power (5%): and wind (1%). Biomass, hydroelectric pumped storage, and petroleum, supplied the rest. Nineteen percent of the electricity from the Hoover Dam goes to Arizona, 23 percent goes to Nevada, and 58 percent goes to California. About 15 percent of the Dam's electricity goes to Los Angeles -a city that is 270 miles away. But you can see from the stats that hydro isn't a major % of the state makeup of power in either AZ or NV, and all the Hoover Dam power is mixed with other dam generation as well to get 'up' to those numbers. Only 5.7% of US electricity last year came from hydro, in the entire country - and it wasn't from Hoover Dam, which is now not all that big a generator. My stats are all audited and straight from the US EIA.
Too bad no mention of the various wave/tidal hydropower systems, which are ecologically friendly, and expandable, and there are going to be continuous tides, either in or out, for a very long time. No need to dam up rivers/lakes, no need for storage. All the coastline the US has it could really be a major source.
@@Morhua1 Thank you, Mattias, I absolutely agree, I was just thinking about relating to hydropower in this instance, but absolutely, anything and everything to get off of fossil fuels and be much less harmful to the environment. After all, it is the ecosystem human life depends on.
Rivers have existed for as long as the earth. Don't worry about their supposed methane gasses released to the atmosphere, which are probably negligible compared to the methane we release with engines and coal plants. I think these scientists need to be more realistic and not alarmist for small things like that (8:26) Everything we do has trade-offs and yes, it will affect the area surrounding the plant *a little* but hydropower is largely beneficial
i think they're mentioning the poor regulated projects which the consequences may outweight its benefits. this kind of project is widely found throughtout southeeast asia and africa as the developing country usually lured by the financing and the seemingly "sustainable & green" power source. yet the environmental risk is often not well studied beforehand. in additional it usually bring job oppprtunity to the local community (which usually doesnt really the case). so I agree with the scientist, to open our eyes wide open to all the pros and cons :)
Rivers being dammed, for less that 100 years in most places. Give me any river with a dam I will give you a list of dead animals and plants, as well as extinct human communities. A reservoir is not a lake, and a river that doesnt flow to the sea is unnatural. It's also why estuaries, deltas, and brackish water ecosystems are dead and gone almost everywhere. It's why freshwater species are mega expensive in places where they were freely available in abundance just 100 years ago.
The total generating capacity of the Grand Coulee Dam is 6,809 megawatts and its average annual energy output is about 2,300 megawatts. The total generating capacity of the Hoover Dam is 2,080 megawatts and its average annual energy output is about 478 megawatts. By using solar and wind to pump water upstream to those two dams, we could increase their output by as much as 6,111 megawatts, with months of storage.
1000 times this. People say solar is no good because it doesn't work at night and batteries are too expensive, but we have giant batteries right there already built that just need some extra equipment and organisation to make full use of them. Government needs to imscentivise this now before we get to the point of really needing it so it can cut the requirements for gas peaking and save CO2 sooner rather than later.

@@seanthe100 90% of the grid in the US is powered by fossil fuels. It should be the other way around: Nuclear should be making up the largest share of the grid with hydro and renewables filling in the gaps
Pumped Hydro is used by companies in Switzerland to store the surplus energy France produces during the night and then re-sell it to France during the day. They do have great mountains to do that. One of the most beautiful things I saw was a system to optimize the Brazilian hydroelectric system made by the University of Campinas. On simulations the system saved 3% of energy but it could not be put to work because of the risk that could cause a general blackout.
There is a wonderful development at Niagara Falls. The hydroelectric generation done on both the Ontario and New York State side of the border and was completed in the 60's with a capacity of 2.4 GW. Better yet an 80 million cubic meter reservoir is allowed to fill up at night and is used to generate power during the day.
Spot On! Nuclear Powered, Desalination and Pumping also has a place. Instead of pumping cooling water back into the local supply, it can be pumped to the highest elevations and allowed to cool on the way down. Why aren't they doing this at Lake Mead and Lake Powell?!? Try water lilies to absorb carbon...
I believe the issue is pressure. Water towers exist to ensure pressure to the taps that they feed, so using some of that energy will lead to lower pressure and less efficiency of the distribution system. That being said, there are thousands of pressure reducing valves in urban distribution systems. Retrofitting these to produce power is a huge untapped (pun intended) opportunity.
@@mkkm945 I considered the idea of running a hydro plant of civil water systems. I was just thinking a dedicated water tower for storing water only for use in the hydro plant. It reduces the need for drinkable water in a system intended to reuse the water in a closed system.
One of the reasons for fewer hydro projects is the environmental damage of flooding that many square miles of land not to mention the wildlife above the dam. Pull some of your own footage from the three gorges dam.
Forgotten? Who forgot about it. It's just either tapped out, or not fully built out on account of the massive environmental damage caused by building dams.
Absolutely no one have forgotten about hydro. Its build where ever possible all over the world constantly because its so good. Go away with your bad click bait.
Just here to let everyone know how something like this in critical time is a death trap. I was born in ucraine and at the moment my grandparents still live there. Currently also my two aunts with their children are there to help a little with farm stuff. Earlier in the year he river which runs besides our village (which is the second biggest river in ucraine) went down a lot, and right now there's almost none of it left. About a week ago something no one would've ever expected happened, water in our own well completely disappeared and the same goes for the public water that arrives from the sink. At the same time light started disappearing quite often. All of this is the sad fate of the "lucky side" of ucraine, the one where there were never attacks and all those things. I guess it's because most of these around ucraine got destroyed during war and the few one which are still there and are in a pretty safe environment have to work for the whole country
In general, hydropower is owned by the government as it is a non competitive industry. I don't know how it is in the US, but in most developped countries, dams are not something you can invest in.
There is still lots of potential to retrofit old hydro and generate more power. The US dept of energy did some of this at the small scale and it worked out very well. Pumped storage biggest issue is finding suitable locations as you often need one lake and a hill to exist already. China likes dam financing as it uses orders massive steel capacity and Chinese labour. High steel demand insures that they keep their lowest end steel costs over other non chinese competitors and as locations for the dam workers end in China, they can be used elsewhere. It also soaks up lots of capital that needs to find a long term home with less risk.
In US there are millions of old oil well that are not sealed and emitting methane. Methane is a powerful greenhouses gas with a 100-year global warming potential 28-34 times that of CO2. Measured over a 20-year period, that ratio grows to 84-86 times.
It needs to be reimplemented largely in States with natural flow basins, waterfalls, things like that. Creek diversion (partial) could also increase outflow, in the event that we need that in certain rivers to create more energy. Drought has killed the West Coast, outside of San Diego, and only because of their DeSal facility. BUT, that needs tons of power to run, so….eeehhhh, we should definitely get on this….now.
You Scandinavians function at a higher level then the rest of us neanderthals. I have some insight into this cuz I'm one quarter Dane!! It's the rest me that's neanderthal! 😂😆🤣
From what I've read, only 5 of the 17 turbines at Hoover Dam are productive down to 950'. The other 12 should have been turned off when water levels fell below 1050' a few days ago. I've seen no reports confirming that this happened.
It's too bad that solar over capacity and production is mostly along the West Coast where the sun rises too early before most businesses are open for the day... And that pumped hydro isn't likely a solution because of massive and widespread drought. Perhaps if long range transmission lines were built to connect the West Coast to maybe the Pacific Northwest where hydro is plentiful could be considered.
The future is for self-generation of electricity off grid, even in California, they came out with a proposed law that makes things difficult for on grid.
Or perhaps the US could actually have a National Grid rather than regional grids with high voltage transmission lines running coast to coast - given the time zones across the US that would give somewhere for California's solar excess a place to go. But US NIMBYism is alive and well in Maine - "A proposal to transport clean hydropower from Canada to the state of Maine has created enough "hoohah" to launch a fierce court battle - possibly signalling trouble for the future of green energy projects across the US. New England Clean Energy Connect (NECEC) was supposed to be an industry-leading project, transporting 1,200 megawatts of Canadian hydropower to Massachusetts across 145 miles (233 km) of transmission line, and eliminating over three million metric tonnes of carbon emissions every year. The $1bn (£840m) project, funded by utility company Hydro-Quebec and Central Maine Power (CMP), which is owned by the Spanish energy giant Avangrid, received final approvals, including a Presidential Permit from the US Department of Energy. Construction began in January 2021. Now, the hydropower project could be dead in the water, after a majority Mainers voted to cancel it last November. The legality of that referendum, as well as the lease for a one-mile stretch of public lands, is currently before the Maine Supreme Court, which could issue its decision any day." www.bbc.com/news/world-us-canada-62072844
So you want to talk about nuclear because it is supposed cleaner then let's start with the cost. A good example to highlight the cost of a nuclear power plant is the Edward Vogtle plant in Waynesboro, GE. That is the only plant now under construction in the country. It is actually two reactors added to the two already present. The estimated cost for these plants is projected to be 25 BILLION $$!!. Length of time to completion from start to finish is more then ten years. They started construction some years ago. People are going to have to make up the cost of these expensive nuclear plants which might be good for 70 years tops. So not cheap any way you look at it. And what about how clean nuclear power plants claim to be? One thing often over looked is prodigious amount of CO2 produced from cement production for the plant construction. And of course there is the highly radioactive waste produced by the plant which the US still hasn't found a permanent home for. It continues to accumulate on the site of the nuclear plants where it is produced. How long can that go on? Then there is also the vast amount of low level nuclear waste which must be stored away indefinitely. And did you say that nuclear power is safe? Did you forget about Fukushima-- complete melt down in at least two plants due to coolant loss because the tsunami wiped out the back up generators. March 11, 2011. There was a partial meltdown of the Three Mile Island plant in 1979. There was the explosion of the Chernobyl nuclear plant in 1986. So whether it is democrat or republican states nobody seems to want the big new nuclear plants because of all the baggage that comes with it. And lastly there is talk of thorium reactors mininuke reactors which supposedly produce less waste. But I see no commercial activity with either option. Maybe the authorities need to talk about it for few more years to decide how to sell it to Americans. 🙄 Any more questions?

Long time investors doesn't exist because they are smart to not bet their money on future politics. In Sweden ALL (roughly 1800) hydropower stations recently lost their right to use the water. And now they have to pay a huge amount of time and money to try getting their rights back through a court order. According to my opinion this political decision was made to strengthen the need and ROI of wind power that is losing money. "If your business is losing a lot money you can either close down or try make life of our competitors even more miserable". I have a very small but fully wildlife adapted 5kw run-of-river hydropower station and ROI for keeping it would be 500 years or so but I will not give up. I will pay and put a stick in the politicians eyes. Sadly most micropower station owner won't have the funds to do the same and will be forced to remove the whole facility and restore the waterway. All this is done while Sweden has an acute shortage of electricity. That is politics in a nutshell.
Hydropower CAN be clean but the mega projects beloved of despotic regimes are often destructive. e.g. Aswan Dam (silted up and caused famines downstream), Three Gorges (flooded a huge gorge and may well collapse) and the dams USSR built which drained the Aral Sea (leaving a toxic desert).
We need much more of it, and we need to stop destroying gigawatt dams to save the two fish that get caught in the screen monthly. Hydro is our only clean energy.
It's not forgotten, just mostly tapped out, and the cons now outweigh the energy benefits in most nations calculations. Much of the easily exploitable river energy has been tapped; China has been reduced to damming the Mekong, crippling its status with the downriver nations, who are suffering major economic hits. Pumped hydro energy storage is nice, but also subject to tight sighting requirements. The other sources of hydropower, like tidal energy, are theoretically simple but technically so challenging we still haven't found an economical way to tap them.
90,000 dams in the U.S. alone. Wow. The dams of the Columbia River basin have provided benefits. However the benefits they created came at great expense to the environment and natural resource economies of the lower Columbia River and coastal and tribal communities along the west coast of north America they supported. Essentially a transfer of wealth from many to create wealth for others. The "real" costs of these dams weren't fully considered or understood.
For me I think hydro power dams on rivers need to move away from total electricity generation ( which as she said is in many places like west USA being going down over the last 20 years away due to drought and slit etc etc … and moving more into slightly smaller dams that hold water for minimum off 18 hours a day but then flush more water per minute out during the few hours off the morning and afternoon peak electricity demand hours…… you simply pair these dams with open bottom dams a bit downstream so that after these perforated dams the rivers run more or less constant just as long as the open bit under these is sized right for an average 24 hour period …… keep the closed water systems more for pumped hydro which along with gravity storage,flywheels and batteries can be used more as excessive energy storage ready to fill in the nights and low wind periods
Hydropower sound good with the old technology. But with the 4 generation nuclear reactor and Lighbridge metallic fuel that operate 1000 Celsius degree cooler than conventional nuclear fuel, you can build the same power capability with NuScale SMR with a fraction of the land needed by Hydropower without any of the environmental damage by Hydropower. And the 4th generation Nuclear reactor with Lightbridge safer nuclear fuel make it a walk away safe that there is no reason not to choose Nuclear over Pump Hydro. And in regard to Pump Hydro storage, you can use Cryobattery energy storage like Highview Power that is pretty much Pump Hydro in a box. Cryobattery use a fraction the amount of land that Pump Hydro use without any of the environmental damage that Pump Hydro cause. So if you are an environmentalist, you would see no future in Hydropower since there are much better option out there.
Wave and tital power can be huge sources of energy . But hydro power through dams is limited since there are few geographic spot that would be suitable
@@joshuaford4460 Indeed, plus there is also Wave power. Dams & reservoirs aren't the only way to make "Hydro power". They should pump & desalinate the oceans some which might bring more rain to droughted areas. 🤔
Sadly 80% of US dams are in disrepair and are at risk of failure. If this was addressed and the US invested in desalination plants to pump filtered sea water back into the lake when river levels are low
That would make a ton of sense, maybe we could even use Saudi Arabias solar desalination plant to get more power out of the system. Basically it works like the close loop solar thermal reactors.
Using dams that already have power capacity and ones that are built already are a great idea. Using recently submerged land rather that adding concrete into the waterways could be a way to go by using the underwater geology to direct the water therefore the current where the power is. Other way are using the water that hits the shore as is already being done putting floating devices that generate power.

The problem with Hydro is the disruption of species who head upstream to spawn. Think Salmon, Eels, Striped Bass. Fish ladders don't work that well honestly. Is the trade-off worth it? Probably. Can we select certain rivers or create new reservoirs that don't have a billion year history of fish breeding and migration? Probably. But that's what needs to be discussed. Edit: I commented before I watched the video.
Hydroelectric power is responsible for 65% of Brazil's electricity generation. Unfortunately, climate change has increased droughts and affected reservoirs in recent years, so there is an increasing demand for solar and wind energy. Currently, the second largest source of generation is wind power.
Here in Brazil, 65% of the electric power comes from hidro power and more than 80% from renewable sources. We have a long experience of building hidroplants, but the newer ones were built as run of rivers because of environmental concerns and are not as efficient as the storage plants.
So, it’s important to find the middle ground between environment and efficiency, but personally I’m huge fan of hidropower.
We have to do the right way, for our future..

Same thing here in BC. We sell to Alberta as well as the US.

Quebèc also sells some of their hydro to Ontario, too!
Hydropower combined with nuclear is great! Nuclear provides all the baseline power and hydro smooths any fluctuations.
Once it's been constructed it's carbon free!
Hell yeah
I like how this video skates around the biggest problem. The water demand of Southern California is killing those lakes more than any other factor.
Hydro is good, imho, as batteries for other sources. It's not a solution for climate change.
You'd think that the methane problem is solvable. It's pretty apparent that it's caused not exactly by the dam's reservoir killing off vast amounts of foliage, but that the reservoir is a permanent feature that eliminates seasonal ebb and flow of flooding, a natural way to rejuvenate the environment and soil. So, what is the solution? Agitate the water to ensure proper oxygen mixing? Periodically intentionally let the water levels drop? Something else?
I expect these dams are run as a commercial operation. Letting all the water run out would reduce the income available while the benefit would be to the climate not the company. Some kind of requirement or incentive would be needed to get them to do it.

@@stickynorth Holland is a waterlogged country, constantly being drained for excess water that they pump into the ocean - I'm not sure they know how to farm in the desert. Or maybe they do - do you have a link?
We here in the Pacific Northwest get the majority of our electricity from hydropower.
It's the best. We also have the Bonneville Power Administration which is a government agency that keeps the rates low and maintains thousands of miles of transmission lines.
That’s right, up here in BC, 95% of our power is from renewable sources, with about 86% of that coming from hydropower.
Quebec has almost 100% with hydro power.
@@Arctic_Adjuster You need to learn more and understand the power grid.
I have often thought that flood waters could be used and pumped into drained aquifers in the Midwest. This would help many farmers whose water wells are drying up. And in turn help the entire country secure our food sources.
generally surfacewaters are not desired to be directly pumped into aquifers due to contamination risk... however a flood recharge where an area is purposefully flooded and allowed to trickle down (thereby getting filtered) is an option that is used in some areas.
That's actually a good idea. It'd probably need treatment and therefore more than just local, 10' x 10', pump houses. Our depleting aquifers are of grave importance though.
I keep asking the SAME THING
true california lets so much water go to waste when they need to improve infrastructure to collect it. they been using too much ground water. as dirty as it sounds imagine if urine was recycled and then used to hydrate californias forest. would prolly avoid using it for agriculture. but it is safe I mean NASA does it all the time.
I’ve considered that as well.
In regards charging aquifers I heard the figure that 30% of the stored water in the Colorado River system leach’s into the sandstone. Was wondering where that ends up.
Pumped storage isn't perfect but for grid scale storage capacity without mining a small planet worth of lithium and cobalt, it's the best bet to make variable sources like solar and wind scale up

Hydropower is one of the cleanest and greenest sources of energy around!! Yet still, there are so many complaints about it. Ugh.
Enviros are idiots
Pointing out issues isn't a bad thing. You need these problems to come to light to correct or mitigate them. We need to ensure that your not destroying the environment so all people, "poor" included, can enjoy it.
You sound like a turn of a century industrialists who complains about not being able to dump chemicals into the river.
Yeah. The methane that would be POTENTIALLY released from a reservoir is miniscule and negligible compared to ALL the methane we realease. Also, rivers have been releasing this supposed methane for thousands of years. It's okay, woman. "But think about the poor fish, they won't be able to swim past the dam!!!" * Palmface *
Environmentalist should have no kids and love in the forests.
@@rh5829 He has a point though. Every month that green energy projects are held up because they aren't *perfect*, is another month that we continue to burn coal and gas powering our electric grid.
As CA is finding out, you need water to make use of hydropower - but it does two things in one, holding water for use in a lake being even more important. Problem is you need to expend a tremendous amount of resources and energy to build a dam and powerplant, which can also take decades from start to finish. People poo-poo nuclear, but it is the easiest non polluting energy source that can be built almost anywhere; but it also takes a lot of energy and resources to build a plant.
Based!
California needs to delay closing Diablo Canyon and repair and restart the San Onofre Nuclear Generating Station. Grid operators are expecting a shortfall of 1.7 gigawatts in California this summer. San Onofre had a capacity of 2.2 gigawatts.
We need both hydro and nuclear, because nuclear has a constant output whereas sometimes we need more or less power. Hydro, whether pumped or not, is the best low carbon dispatchable generation. Use excess solar in the day and nuclear at night to pump up hydro then let it out at peak times and during the winter when solar produces less. They can all work together really well.
@@adrianthoroughgood1191 That's not exactly true. Nuclear plants can do load following, and be even quicker at it than CCGT. Hydro is the quickest one at it with both turbining and pumps, not accounting for batteries (which are very resource intensive). Thing with Nuclear is that load following with most reactor designs is a waste.
Overall I agree with you. Nuclear for baseload (maybe a bit over minimum maximum demand), Solar for the increased demand during the day, I especially like rooftop solar and floating panels at Hydropower reservoirs (reduces evaporative losses and uses already built wiring to connect to the grid). And Hydro working as the balancer between all.
yep I served on nuclear powered submarines, never more than 600 feet from a running reactor core....longest I've been underwater is 87 days....it's a great source of power, compact footprint lots of power no pollution. :)
I was seriously expecting to hear about the potential of floating solar, and how that could eliminate the need for releasing water during the day. That would allow for *increased* hydropower generation during the night.
Especially at locations like Hoover which are running below design capacity due to lack of water. Makes better use of existing infrastructure.
@@NVGEAR Floating solar would be cheaper, faster to build, would have minimal hookup costs because the dam already has a grid hookup, the panels would enjoy increased efficiency from the water and produce more power, the panels would last longer, the arrays can be rotated to track the sun, the arrays reduce evaporation, and the arrays would reduce sunlight making its way to the bottom, which would reduce biomass growth and reduce CH4 emissions from reservoirs. Why would they not invest in floating solar? There's no reason not to.
@@NVGEAR It's faster, cheaper, and the cost to link it to the grid is next to nothing.
@@firefox39693 And you don't need to clear whole swathes of land to install the panels. There are Hydro reservoirs that are absolutely humongous. You wouldn't cover them whole, but covering like 50% in a well designed way would not have a big impact on the biomes. You could inject it into the grid, and do some PSH on top. But I bet you that operators would just use it all for pumping, and then release it during the dinner peaks.
@@AlldaylongRock
Yes, you just pointed out that combining them, by using solar to pump into storage makes sense and increases simplicity by using a dedicated separate pumping system. Storage capacity can easily be accomplished by increasing the reservoir's volume.
As far as I'm concerned, hydropower is great, we should keep doing it, look for ways to make it better and so on, but it doesn't have the potential to supply much more energy than it is already supplying. Wind and solar, on the other hand, have huge potential to grow since we need a massive amount of renewable energy and they are the only sources that could meet the world's energy needs. So the headlines are deserved.
Misinformation.
Nuclear is the way.
actually fam if as good as hydro is in generating power and regulating water flow to prevent floods. down side is water flow can become political and can damage eco systems that rely on water. look at how much water loss has occurred in the colorado river. with that being said Nuclear is the way to go with only biproduct of water vapor or steam and ofcourse the decay of radioactive material. however with regards to removing radioactive material we can just launch it to the moon through NASA's atermis program and spacex falcon heavy.
yes you Right
Yeah but we haft to dig for lithium for batterys and that releases a lot of carbon & U.S. uses African children to do the mining they often die & dont get paid enough
Indeed. Hydro development ought to involve protection of water catchment areas which produce the rivers that the reservoirs depend on. It can even be combined with environmental conservation efforts like afforestation, reforestation and agroforestry. Minihydro, microhydro and picohydro plants are also useful for small and off-grid areas. Tidal and wave energy also count as hydro.
OH NATHAN - LIE-berals DO NOT WANT YOUR SUGGESTIONS regarding water power!!!!!!!!!!!!!!!!!!!!

The upkeep is minimal and the environmental tradeoff is a no brainer.
I live in Wisconsin and many cities that are on a river have a power generating dam in the city (at least along the WI River). I think these dams could use some investment and be improved, but power producing dams are. Or overlooked. They are everywhere in WI.
But you have to look at the environmental impacts of these dams and what they do to the river ecosystems. Fish depend on getting from ace to place in these rivers and all a dam is, is a barrier to them.

Not only forgotten energy but forgotten free battery if you use a second flow management dam to allow the river flow to be maintained at a safe level while the turbine in the main dam is opened and closed based on the minute to minute power needs of the grid. Instead of dams producing power that is used to pump water uphill so you can get hydropower when you release it you simply close the dam gates until you actually need the power.
Not forgotten, it’s just not mainstream.
@@KRYMauL I believe many dams have variable for l floor capacity, actually... They effectively already do this.
What about the environmental damage. We are taking out the dams on the Klamath river to restore fish runs and the farming areas.
In Québec, the hydro power generation is dynamically adjusted. When wind/solar production goes up, they immediatly reduce flow of water through dams. This preserves the water in the reservoir and is far mreo efficient than letting it flow down and pump it back up. Hydro is our base load, we don't have nuclear or any sizeable fossil fuel production on the main grid.
Where you have non-dymanic base load such as nuclear plants that take hours to adjust production instead of seconds, you can't do that and you end up with surpluses when wind/solar produce.
If you consider the environment damage to the lower stream then it’s not so clean anymore.

Dams in the US need to be rethought. We have minerals and fish migrations that are crucial to keeping plant life that in turn will help the water table hold water. These canyons have become deserts more since we have put the dams in place since nature can’t establish what it needs to create a healthy ecosystem
Amen to that 🙏🏼
Not to mention we can’t keep the damns infrastructure up to code.
Here's my answer to hydropower:
Lake Mead (which powers the Hoover dam and a huge part of 2 states and northern Mexico. Not to mention providing water to those same places - that can't be replaced)
The combination of a changing climate and strong demand for the lake’s remaining water has resulted in a 100-foot drop in the reservoir since 2000. That’s just 10 percent under the lake’s high water mark in 1983, Lake Mead is shaped like a martini glass-wide at the top and narrows at the bottom.
If the reservoir drops below 895 feet a possibility still years away Lake Mead would reach dead pool status, with potentially catastrophic consequences for millions of people across Arizona, California, Nevada, and parts of Mexico. Additionally, the power created by Hoover Dam is used to carry water up and across the Sierra Nevada Mountains on its way to supplying Southern California.
So you see, hydropower is not flawless, and can go away when climate is unstable. Frankly, we need different sources of power, even fossil fuel power (for the immediate future) until we can reach carbon neutral (which we probably never will based on what I know about people).
Not a real major contributor in NV or AZ - Most goes to CA.... not sure any goes directly to MX per EIA stats...
AZ - electricity by source in 2022, 99% of Arizona's total electricity net generation was provided from 6 sources: natural gas (42%); nuclear power (29%); coal (12%); solar energy (10%); hydroelectric power (5%): and wind (1%). Biomass, hydroelectric pumped storage, and petroleum, supplied the rest.

Nineteen percent of the electricity from the Hoover Dam goes to Arizona, 23 percent goes to Nevada, and 58 percent goes to California. About 15 percent of the Dam's electricity goes to Los Angeles -a city that is 270 miles away. But you can see from the stats that hydro isn't a major % of the state makeup of power in either AZ or NV, and all the Hoover Dam power is mixed with other dam generation as well to get 'up' to those numbers.
Only 5.7% of US electricity last year came from hydro, in the entire country - and it wasn't from Hoover Dam, which is now not all that big a generator.
My stats are all audited and straight from the US EIA.
Too bad no mention of the various wave/tidal hydropower systems, which are ecologically friendly, and expandable, and there are going to be continuous tides, either in or out, for a very long time. No need to dam up rivers/lakes, no need for storage. All the coastline the US has it could really be a major source.
We will need every type of renewable technology.
@@Morhua1 Thank you, Mattias, I absolutely agree, I was just thinking about relating to hydropower in this instance, but absolutely, anything and everything to get off of fossil fuels and be much less harmful to the environment. After all, it is the ecosystem human life depends on.

Storage is a huge potential positive of hydropower because of pumped storage. Tidal is not commercially viable at the moment.
Tidal is more dependent on Geography than Hydropower.
There is a reason its not used as much. Not many places can work for Tidal power.
Rivers have existed for as long as the earth. Don't worry about their supposed methane gasses released to the atmosphere, which are probably negligible compared to the methane we release with engines and coal plants. I think these scientists need to be more realistic and not alarmist for small things like that (8:26) Everything we do has trade-offs and yes, it will affect the area surrounding the plant *a little* but hydropower is largely beneficial
i think they're mentioning the poor regulated projects which the consequences may outweight its benefits. this kind of project is widely found throughtout southeeast asia and africa as the developing country usually lured by the financing and the seemingly "sustainable & green" power source. yet the environmental risk is often not well studied beforehand. in additional it usually bring job oppprtunity to the local community (which usually doesnt really the case). so I agree with the scientist, to open our eyes wide open to all the pros and cons :)
Rivers being dammed, for less that 100 years in most places. Give me any river with a dam I will give you a list of dead animals and plants, as well as extinct human communities. A reservoir is not a lake, and a river that doesnt flow to the sea is unnatural. It's also why estuaries, deltas, and brackish water ecosystems are dead and gone almost everywhere. It's why freshwater species are mega expensive in places where they were freely available in abundance just 100 years ago.
The total generating capacity of the Grand Coulee Dam is 6,809 megawatts and its average annual energy output is about 2,300 megawatts. The total generating capacity of the Hoover Dam is 2,080 megawatts and its average annual energy output is about 478 megawatts. By using solar and wind to pump water upstream to those two dams, we could increase their output by as much as 6,111 megawatts, with months of storage.
1000 times this. People say solar is no good because it doesn't work at night and batteries are too expensive, but we have giant batteries right there already built that just need some extra equipment and organisation to make full use of them. Government needs to imscentivise this now before we get to the point of really needing it so it can cut the requirements for gas peaking and save CO2 sooner rather than later.
Not entirely against it but it seriously f’s up some ecosystems. Not perfect what so ever. We need more nuclear and that’s about it

Pumped Hydro is used by companies in Switzerland to store the surplus energy France produces during the night and then re-sell it to France during the day. They do have great mountains to do that. One of the most beautiful things I saw was a system to optimize the Brazilian hydroelectric system made by the University of Campinas. On simulations the system saved 3% of energy but it could not be put to work because of the risk that could cause a general blackout.
There is a wonderful development at Niagara Falls. The hydroelectric generation done on both the Ontario and New York State side of the border and was completed in the 60's with a capacity of 2.4 GW.
Better yet an 80 million cubic meter reservoir is allowed to fill up at night and is used to generate power during the day.
Hydropower is not forgotten, it's just that the harm these plants do to rivers and their ecosystems are not cost free
I live in california, we dont have enough water to run them. In fact they should shut them all down until we are out of the drought.
Spot On! Nuclear Powered, Desalination and Pumping also has a place. Instead of pumping cooling water back into the local supply, it can be pumped to the highest elevations and allowed to cool on the way down. Why aren't they doing this at Lake Mead and Lake Powell?!? Try water lilies to absorb carbon...
The fight against nuclear power was propagated by big oil!
We need hydroelectric dam modernization, renovation, and restoration in the United States.
People forget ofton that these dams practically wipe out all migrating fish.
A water tower could be used for small scale water storage, they have also been used for years.
I believe the issue is pressure. Water towers exist to ensure pressure to the taps that they feed, so using some of that energy will lead to lower pressure and less efficiency of the distribution system. That being said, there are thousands of pressure reducing valves in urban distribution systems. Retrofitting these to produce power is a huge untapped (pun intended) opportunity.
@@mkkm945 I considered the idea of running a hydro plant of civil water systems. I was just thinking a dedicated water tower for storing water only for use in the hydro plant. It reduces the need for drinkable water in a system intended to reuse the water in a closed system.

Just here to let everyone know how something like this in critical time is a death trap. I was born in ucraine and at the moment my grandparents still live there. Currently also my two aunts with their children are there to help a little with farm stuff.
Earlier in the year he river which runs besides our village (which is the second biggest river in ucraine) went down a lot, and right now there's almost none of it left.
About a week ago something no one would've ever expected happened, water in our own well completely disappeared and the same goes for the public water that arrives from the sink. At the same time light started disappearing quite often.
All of this is the sad fate of the "lucky side" of ucraine, the one where there were never attacks and all those things.
I guess it's because most of these around ucraine got destroyed during war and the few one which are still there and are in a pretty safe environment have to work for the whole country
What stocks do you recommend based on this information about the future of hydropower ?
BP, Shell, Exxon
In general, hydropower is owned by the government as it is a non competitive industry. I don't know how it is in the US, but in most developped countries, dams are not something you can invest in.
Those are monumental undertakings
1:03 - Only 3% of US damps produce power ?!? This is mind-boggling! What were you people thinking ?
if its so clean. Tell me what it takes to build one of these?
They didn't mention all of the fossil fuel that was used to have it built in the first place. Fools!
There is still lots of potential to retrofit old hydro and generate more power. The US dept of energy did some of this at the small scale and it worked out very well. Pumped storage biggest issue is finding suitable locations as you often need one lake and a hill to exist already. China likes dam financing as it uses orders massive steel capacity and Chinese labour. High steel demand insures that they keep their lowest end steel costs over other non chinese competitors and as locations for the dam workers end in China, they can be used elsewhere. It also soaks up lots of capital that needs to find a long term home with less risk.
In US there are millions of old oil well that are not sealed and emitting methane. Methane is a powerful greenhouses gas with a 100-year global warming potential 28-34 times that of CO2. Measured over a 20-year period, that ratio grows to 84-86 times.
Hydro and electricity are synonymous if you talk to a Canadian
It needs to be reimplemented largely in States with natural flow basins, waterfalls, things like that. Creek diversion (partial) could also increase outflow, in the event that we need that in certain rivers to create more energy. Drought has killed the West Coast, outside of San Diego, and only because of their DeSal facility. BUT, that needs tons of power to run, so….eeehhhh, we should definitely get on this….now.

I like to pronounce Mojave like "Mojave".
"Renewable" but has not been actively renewed, so it is likely to fail because of the record drought.
While climate change increase drought conditions in dry regions, it increases precipitations in wet regions, making hydropower even more performant
From what I've read, only 5 of the 17 turbines at Hoover Dam are productive down to 950'. The other 12 should have been turned off when water levels fell below 1050' a few days ago. I've seen no reports confirming that this happened.
Vegas needs its electricity fix.
Are you saying renewal energy sources are unreliable? Damn someone is doing their homework! That said, pollution must be curtailed.
It's too bad that solar over capacity and production is mostly along the West Coast where the sun rises too early before most businesses are open for the day... And that pumped hydro isn't likely a solution because of massive and widespread drought. Perhaps if long range transmission lines were built to connect the West Coast to maybe the Pacific Northwest where hydro is plentiful could be considered.
The future is for self-generation of electricity off grid, even in California, they came out with a proposed law that makes things difficult for on grid.
They could combine solar with desalination plants that pumps water into lakes and reservoirs. This basically works as a solar thermal power plant.
Or perhaps the US could actually have a National Grid rather than regional grids with high voltage transmission lines running coast to coast - given the time zones across the US that would give somewhere for California's solar excess a place to go. But US NIMBYism is alive and well in Maine -
"A proposal to transport clean hydropower from Canada to the state of Maine has created enough "hoohah" to launch a fierce court battle - possibly signalling trouble for the future of green energy projects across the US.
New England Clean Energy Connect (NECEC) was supposed to be an industry-leading project, transporting 1,200 megawatts of Canadian hydropower to Massachusetts across 145 miles (233 km) of transmission line, and eliminating over three million metric tonnes of carbon emissions every year.
The $1bn (£840m) project, funded by utility company Hydro-Quebec and Central Maine Power (CMP), which is owned by the Spanish energy giant Avangrid, received final approvals, including a Presidential Permit from the US Department of Energy. Construction began in January 2021.
Now, the hydropower project could be dead in the water, after a majority Mainers voted to cancel it last November.
The legality of that referendum, as well as the lease for a one-mile stretch of public lands, is currently before the Maine Supreme Court, which could issue its decision any day."

Are we going to talk about nuclear power and how safe and its way cleaner than coal and natural gas?
Fukushima. . Chernobyl. Three mile island. Safe? No. Ecological disasters. Global disasters. Get a clue. Radiation is deadly.
So you want to talk about nuclear because it is supposed cleaner then let's start with the cost.
A good example to highlight the cost of a nuclear power plant is the Edward Vogtle plant in Waynesboro, GE. That is the only plant now under construction in the country. It is actually two reactors added to the two already present. The estimated cost for these plants is projected to be 25 BILLION $$!!. Length of time to completion from start to finish is more then ten years. They started construction some years ago.
People are going to have to make up the cost of these expensive nuclear plants which might be good for 70 years tops. So not cheap any way you look at it.
And what about how clean nuclear power plants claim to be? One thing often over looked is prodigious amount of CO2 produced from cement production for the plant construction.
And of course there is the highly radioactive waste produced by the plant which the US still hasn't found a permanent home for. It continues to accumulate on the site of the nuclear plants where it is produced. How long can that go on? Then there is also the vast amount of low level nuclear waste which must be stored away indefinitely.
And did you say that nuclear power is safe? Did you forget about Fukushima-- complete melt down in at least two plants due to coolant loss because the tsunami wiped out the back up generators. March 11, 2011. There was a partial meltdown of the Three Mile Island plant in 1979. There was the explosion of the Chernobyl nuclear plant in 1986.
So whether it is democrat or republican states nobody seems to want the big new nuclear plants because of all the baggage that comes with it.
And lastly there is talk of thorium reactors mininuke reactors which supposedly produce less waste. But I see no commercial activity with either option. Maybe the authorities need to talk about it for few more years to decide how to sell it to Americans. 🙄
Any more questions?

Unfortunately the bill for water management 😕 has come due. Well the US had over 20 years to address the problem and here we are. Countries like Isreal which recycles nearly 90 percent of their water, the Netherlands, and Singapore are also leaders in the field. Heavy investments, licensing, and environmental concerns: there may never be a perfect scenario, but doing little or nothing is just not an option any more.

The crypto market has been favourable in the past weeks, I keep missing out on this opportunity, I'm most certainly very impatient how can I ever make a profit in the crypto market.*
There are platform where you can invest and they trade your money. Then pay you profit either weekly or monthly. That's investing.
Despite the financial crisis, this is still a good time to invest in Crypto as the market is favourable💰💱

Long time investors doesn't exist because they are smart to not bet their money on future politics.
In Sweden ALL (roughly 1800) hydropower stations recently lost their right to use the water. And now they have to pay a huge amount of time and money to try getting their rights back through a court order. According to my opinion this political decision was made to strengthen the need and ROI of wind power that is losing money.
"If your business is losing a lot money you can either close down or try make life of our competitors even more miserable".
I have a very small but fully wildlife adapted 5kw run-of-river hydropower station and ROI for keeping it would be 500 years or so but I will not give up. I will pay and put a stick in the politicians eyes. Sadly most micropower station owner won't have the funds to do the same and will be forced to remove the whole facility and restore the waterway.
All this is done while Sweden has an acute shortage of electricity. That is politics in a nutshell.
Hydropower CAN be clean but the mega projects beloved of despotic regimes are often destructive. e.g. Aswan Dam (silted up and caused famines downstream), Three Gorges (flooded a huge gorge and may well collapse) and the dams USSR built which drained the Aral Sea (leaving a toxic desert).
We need much more of it, and we need to stop destroying gigawatt dams to save the two fish that get caught in the screen monthly. Hydro is our only clean energy.
Only 5 out of 17 generators are online at Lake Mead due to low water levels
It's not forgotten, just mostly tapped out, and the cons now outweigh the energy benefits in most nations calculations. Much of the easily exploitable river energy has been tapped; China has been reduced to damming the Mekong, crippling its status with the downriver nations, who are suffering major economic hits. Pumped hydro energy storage is nice, but also subject to tight sighting requirements. The other sources of hydropower, like tidal energy, are theoretically simple but technically so challenging we still haven't found an economical way to tap them.
90,000 dams in the U.S. alone. Wow. The dams of the Columbia River basin have provided benefits. However the benefits they created came at great expense to the environment and natural resource economies of the lower Columbia River and coastal and tribal communities along the west coast of north America they supported. Essentially a transfer of wealth from many to create wealth for others. The "real" costs of these dams weren't fully considered or understood.
No. Without the electricity to power households, you would instead need to burn forests or massive quantities of coal and oil to replace it
For me I think hydro power dams on rivers need to move away from total electricity generation ( which as she said is in many places like west USA being going down over the last 20 years away due to drought and slit etc etc … and moving more into slightly smaller dams that hold water for minimum off 18 hours a day but then flush more water per minute out during the few hours off the morning and afternoon peak electricity demand hours…… you simply pair these dams with open bottom dams a bit downstream so that after these perforated dams the rivers run more or less constant just as long as the open bit under these is sized right for an average 24 hour period …… keep the closed water systems more for pumped hydro which along with gravity storage,flywheels and batteries can be used more as excessive energy storage ready to fill in the nights and low wind periods
Yes! Let's build more rivers!
Hydropower sound good with the old technology. But with the 4 generation nuclear reactor and Lighbridge metallic fuel that operate 1000 Celsius degree cooler than conventional nuclear fuel, you can build the same power capability with NuScale SMR with a fraction of the land needed by Hydropower without any of the environmental damage by Hydropower. And the 4th generation Nuclear reactor with Lightbridge safer nuclear fuel make it a walk away safe that there is no reason not to choose Nuclear over Pump Hydro.
And in regard to Pump Hydro storage, you can use Cryobattery energy storage like Highview Power that is pretty much Pump Hydro in a box. Cryobattery use a fraction the amount of land that Pump Hydro use without any of the environmental damage that Pump Hydro cause.
So if you are an environmentalist, you would see no future in Hydropower since there are much better option out there.
Wave and tital power can be huge sources of energy .
But hydro power through dams is limited since there are few geographic spot that would be suitable
Tidal power don't work.
just build it in mexico then
Have fun designing machines that need to move AND exist in salty water.
5:51 the largest Pumped Storage station is In fact Fengning Pumped Storage Power Station 3600 MW , not Bath County Pumped Storage Station 3003MW !
The oceans have unlimited water. It only makes sense the use that.
Why doesn’t we do that?
Tidal power is in research in several places atm, the difficulty comes in potential wildlife impact as well as maintenance feasability and cost
@@joshuaford4460 that maintenance would be killer
@@joshuaford4460 Indeed, plus there is also Wave power. Dams & reservoirs aren't the only way to make "Hydro power". They should pump & desalinate the oceans some which might bring more rain to droughted areas. 🤔
@@joshuaford4460 it will be a great study how we can make it environment friendly and ways we can solve the maintenence cost issue.
It should be forgotten. It has caused incalculable ruin of ecosystems.
I don't know if I should watch this now or when you inevitably put it into a CNBC Marathon video :/
It has a huge impact too
Negative impact i mean
In Brazil this energy source its much common.
Thanks for watching☝️Get-in-touch , Let's discuss on Financial investments
Sadly 80% of US dams are in disrepair and are at risk of failure.
If this was addressed and the US invested in desalination plants to pump filtered sea water back into the lake when river levels are low
That would make a ton of sense, maybe we could even use Saudi Arabias solar desalination plant to get more power out of the system. Basically it works like the close loop solar thermal reactors.
Using dams that already have power capacity and ones that are built already are a great idea. Using recently submerged land rather that adding concrete into the waterways could be a way to go by using the underwater geology to direct the water therefore the current where the power is. Other way are using the water that hits the shore as is already being done putting floating devices that generate power.

Environmentalists are a genuine party poopers...
And when heavy rain, the release of water from dam makes flood
No mention of the Columbia River system.
The problem with Hydro is the disruption of species who head upstream to spawn. Think Salmon, Eels, Striped Bass. Fish ladders don't work that well honestly.
Is the trade-off worth it? Probably. Can we select certain rivers or create new reservoirs that don't have a billion year history of fish breeding and migration? Probably. But that's what needs to be discussed.
Edit: I commented before I watched the video.
There’s ways to help that. Basically you send the fish through a non powering pump.
Why would you comment before watching the video?
There’s nothing clean about hydro power ☝️
No water! They’re tearing damns down everywhere.
I'm enjoying the video and I'm a big fan of hydroelectric power, however I can barely hear the narrator. ☹
Environmental impact of Dams is too much of a disruption for enviros
No mention of silt. All dams collect silt, some faster than others. When a reservoir is silted up its usefulness is over.
Here in Quebec 99% of electricity is made by hydroelectricity.
We can’t have energy with 100% renewable 🤯
which companies can we invest in with hydro?
Hydroelectric power is responsible for 65% of Brazil's electricity generation. Unfortunately, climate change has increased droughts and affected reservoirs in recent years, so there is an increasing demand for solar and wind energy. Currently, the second largest source of generation is wind power.
