  • I’m sure it was already mentioned but that facility, as stated, used the grid to pump and refill the upper reservoir(I’m sure during off peak hours or with use of renewable’s during their peak outputs) so without a consistent and reliable source of grid power you can’t use one of these facilities to “wind up” the other. Or youd need such a number of these that the logistics of it would be untenable.... in short... it’s so impractical you might as well just go nuclear.....

  • Solar and Wind renewables are not entirely clean, really no energy source is. Solar requires mining of rare earth metals. Wind turbines are vulnerable to some damages and effect natural migration of birds. Coal, well you know already. Natural Gas, there are two versions to this and that is there are net neutral carbon emission gases and not. Fossil/Oil, not even a question. Biomass generators, literally it’s coal just worst. Dams, pretty good actually, only a few problems that are about downstream effects. Nuclear plants, I hate how people forget that these are actually very clean, the nuclear waste is also usually safely disposed (like very far underground), the only problem is usually the system critical scenario that’s leads to radiation leaks from damage to the reactor from bad design to natural disasters. Nuclear fusion, not yet possible, and really high output of energy, we are talking about trying control the reaction that happens in our star’s heart. Hydrogen, not bad actually, just really hard to trap it and sometimes to costly (I’m not as well versed with it). I can’t think much more really. But don’t think your solar and wind are the saviors, they are not. If we want to fix global warming we do it in one way, plant more damn trees (like millions, it’s the best way to reduce the stupid CO2 already) and stop the process of releasing other Greenhouse gases. Those the major problem, not CO2, it’s those that are harder to fix when they are already out there. Anyway enjoy, sometimes I wish the marvel universe was real. Then Tony’s reactor would do major things for us. But I don’t want Thanos tho. The idea of getting rid of nuclear tho is stupid, it’s one of the best ways to get energy and the curiosity and perseverance rovers use a form nuclear decay (alpha) to power themselves because the solar panels didn’t work too well for the previous ones.

  • The strength, precision, and complexity of pumped storage is impressive.. However, in a way, that makes a strong case for battery storage. Compare a battery farm's ease of set-up, lack of moving parts, flexibility of siting, and modular construction allowing gradual expansion and maintenance of parts. If batteries continue to improve and their prices continue to drop, there is no contest.

  • How about building the upper reservoir on groundlevel and the lower reservoir in underground storage structures? This could- 1. Eliminate the evaporation losses to some extent in the lower reservoir. 2. Can open up plain areas for the contruction of pumped hydro electric plants 3. Could be integrated with solar power plants so that when excess solar power is present, it could be used to pump back the water to above ground level.

  • Overall a great video, but I would like to point out that the subsidies statement is quite misleading, as coal produces a lot more power. If you calculate it as dollars per TWh, for coal you get around $10.19M/TWh, and for wind you get around $89.51M/TWh. (These numbers are based on 2019 numbers from ourworldindata.org/grapher/global-primary-energy for the energy generation, and the subsidies are sourced directly from the video)

A few hundred people are literally using this diversion bullshit to crown themselves rulers of the world and give us these imaginary problems that end up destroying the env and emitting more co2 and using blood minerals and so much more for things like lithium ion batteries that need to be replaced in 10 years and don't recycle well. Lovely isn't it that we have made something less efficient than fucking fossil fuels that just hides all its emissions and evil during the manufacturing and disposal processes. Just stop supporting these fucking insane people. Nuclear is the answer to global warming, we will still need fossil fuels in industry, get over it...seriously, people can't think critically anymore and can only see surface level details nor do they look at motives behind why people want them to do things. If you do understand these nuances and see the world for what it is....if you are a guy lets be friends and if you are a girl, let's make some smart bebies! Hmmmm...*thinks like current political climate and imperialist plutocrats*..."bebies are renewable...lets use them for energy!

  • This video has now around 500.000 views. Assuming everyone watches on a laptop that draws 10W (probably more like 15) while watching this used up 10 * 500.000 / 4 Wh (rounding down the video length to 15 min). This makes 1.25 MWh of energy used. This does not include the power consumed by the local wifi router (probably around 15W), the efficiency of the laptop charger (probably 90%), the losses from charging and discharging the laptop battery (lets say 95% efficiency). The again, some people probably watch this on their battlestation, rocking some shiny i7 and a high end graphics card, running at around 100W while in idle. Oh, also 40W for the absolutely necessary 4K Screen. If you are cynical add in a few watts for a usb powered Coffe mug warmer. (Also i did not include the power consumption of the servers and all the communication stations in between youtube and the viewer. Can't have people scared by that, can we? ;) ) Maybe as a thought experiment... how much worse would it be if this video was uploaded in 4K vs 720p and does that even matter?

  • Your totally wrong about fossil fuel prices vs clean Nat gas is super cheap and can produce huge amounts of power in a tiny footprint .. the only way solar or wind would compete is with it is the subsidies and the fact we roadblock fossil fuels and make it more expensive now.. and FYI if we could actually swap over to total clean in 20 years which btw will never happen .. the world's climate will still be ruined for humans.. another FYI nuclear is far superior to either but we roadblock that also

  • fossil fuel 4x more subsidy... also much more massive than renewables, for a net subsidy that over-favors renewables. Foreign wars need not occur over fossil fuels when the US has its own supply and doesn't need that foreign shit, nor the things associated with it. That's purely political, just like renewables. Also, the term "renewables" is a bullshit misnomer, because you have to replace them constantly and renew them with sweet subsidies. It's not something for nothing. This video couldn't have come at a better time, as it's revealed just how worthless and shitty solar and wind power are, and reveals how China has been using it as an excuse to landgrab in the US, while not securing electrical power for citizens of the US. I don't see why you have to shill this garbage so hard, but as long as you're getting your pockets lined, right?

  • I think you read the subsidies stats wrong. You only used the year. You didn't take into account that non renewable are fewer used than all other methods. You did not show the amount per total power or per watt generated. Also the statement that it can generate "more than enough" is bluntly false as we, as we all know this. That title takes nuclear. Seems your religion has no problem replacing green meadows with blue panels and forests with white towers by super charging humanities reach into the animal kingdom. Killing them also, especially the endangered ones. To me it's simple. It's smaller and Thorium nuclear reactors or it's death by forced human depopulation. Agent Smith and Einstein were right.

  • In addition, instead of quoting gross "subsidy" dollar amounts in absolute terms, how about as a percent of total capital investment each year? Because your "large" subsidy number quoted for fossil fuels is large because the investment is and has been large. Show it on a percent basis. You are twisting facts to push an agenda.

  • Lumping all tax deductions into a single bucket and calling them "Subsidies" mischaracterizes them. MOST of the tax breaks being lumped together and called Subsidies here are tax breaks that are available to ALL companies that invest in capital projects. The tax breaks (that you characterize as Subsidies) that are claimed by fossil fuel companies are ALSO claimed by any manufacturer that builds a plant, builds a building, or makes any other capital investment. A manufacturer gets to depreciate their plant investment, as does a fossil fuel company. Stop characterizing tax breaks available to all companies that invest as a Subsidy. It misrepresents the truth. Subsidies (tax breaks) taken by renewable energy generators are NOT available to other manufacturers and investors. Really are Subsidies.

  • I'd be curious as to the ability to use freshwater lakes as a lower reservoir, and rather than releasing into the lake, releasing to groundwater, which would eventually find its way there, and pumping up from the lake, possibly using an aqueduct. Could open a lot of new areas as you could be, A. further from your lower reservoir, and B get more efficient generation as you could pump up a shorter distance than you release down by leveraging tidal forces. Example from my area, rochester NY, being doing this in Irondequoit bay

  • Have you already looked into solid storage ways; in Sweden there is a crane structure which can store energy by lifting and lowering concrete blocks. In the usa they do something similar with train cars. I saw a Dutch documentary about it (Tegenlicht). There's also energy storage in iron; burning Iron and renew the rust into iron again. And can you do a video about heat storage; in Germany Siemens create big energy storage facilities by locking heat in volcanic rock. And this can be done in decommissioned coal power plants; using the already existing infrastructure and keeping the people at work. Lowering the decommissioned costs and startup costs.

  • Should have mentioned the island of El Hierro, in the Canary Islands, Spain. The island has a complex with 5 wind turbines and a higher and lower reservoir. The 5 wind turbines are used to power the island and when there is excess energy, it is used to pump water up to the higher reservoir. When there is not enough wind to power the island, the water is dropped from the top reservoir to the bottom reservoir through pipes, where 3 water turbines convert the water's kinetic energy into electricity. This way, the island has managed to power itself without fossil fuels for even days in a row, and maybe for even longer but I cannot confirm that. There is also a back-up fossil fuel plant that also generates electricity when needed.

  • WHAT HAPPENS WHEN TWO MILLION EV CARS COME ON LINE?

    ArizVernArizVernVor Tag
    • @Massimo O'Kissed Your talking about in the future. I'm talking about 2021 when one million cars are delivered to customers, 2022 will be two million, 2023 four million deliveries. Tesla has no equipment on board to give external power, except Cybertruck. Today EV factories can't keep batteries from catching on fire in your garage.

    • All those batteries could actually work as extra grid load balancing. Effectively like a pumped hydro in every home.

  • Hahahaha the primary factory holding back solar panels, forget EVERYTHING ELSE. SOLAR SOLAR SOLAR, and then you get introduced to carbon credits hahahahah

  • In the US we have immense natural gas reserves. The first natural gas power plant with zero CO2 emissions has been built. Turbine driven generators are vital for providing the inertia to keep the frequency necessary for the power grid. Battery storage for solar comes at a huge environmental cost and it has to be replaced relatively often. Think of all the manufacturing and mining required to produce them. Also wind and solar are dreadful eyesores ruining once beautiful landscapes. They are also terribly harmful to wildlife especially our beautiful raptors which keep the rodent species population in check. Solar plants literally set birds in flight on fire and we know what wind turbines do. I call it renewable blight. I am a member of an Electric Co-op which uses hydro and geothermal. This makes more sense.

  • Renewables require batteries. Batteries are made out of mined minerals. If less things use fossil fuel, more things will use batteries. Less use of fossil fuel and more use of batteries means less oil drilling, but much much more mining. You ever see a lithium mine? Back to the drawing board boys.

  • Your lifecycle comment on the Stored hydro facility are real nice but now, do some research and tell us about the lifecycle of windmills. Presently you get only 20 to 30 years and those are terrible low numbers. To rebuild or build new windmills every 20 to 30 years is counter productive as it takes a lot of steel ,copper and recycling issues.

  • Cold storage of nitrogen makes more sense. A similar concept of chemically storing energy but doesn't need the height.

  • You Sir, are a corporate puppet. You do nothing but babble on about how big and complex your corporate system would be to produce electricity. I live in a standard suburban house on a standard suburban block of land. But I have gathered a lot of free water tanks, pipe lines, rigged generators and using second hand materials built pressure pumps that keep pumping, at no cost, the water into the highest tank, which is also fed from the rain gutters on the house. This miniature hydroelectric system cost nothing for the materials to construct it, it never stops producing electricity for our house, it doesn't need batteries nor does it need environmentally disastrous windmills or, even worse, solar panels that are short lived and if damaged become carcinogenic. So stop being a corrupt corporate shill and tell people how to make their own power and leave your God Cursed Fascist Corporations out of it.
