Humanity wont go extinct but the coming chaos will lead to disruption in the supply chain and while civliazation won't go back to the stone age or even a hybrid of now and the 1900s not everywhere will stay at our current tech level

  • 80% efficiency seems so generous, it's disingenuous. The generator alone is 80% efficient but that's not including the efficiency of the motor pumping water into the reservoir and the various mechanical losses such as head loss from the water moving in and out of the reservoir.

  • There are pros and cons with everthing. Something tells me you use way more power to pump all that water up than you make on it's way down. This solution is a capacitor that has many flaws. I feel like the way better solution would be a flywheel. Recent flywheel technology have progressed significantly. They cost less, take far less space compared to lakes, can work for longer that 5 hours and you can have a lot of them one next to another. While I like wind power the most, I'm sure the nuclear, fission or fusion, is most stable and efficient solution of them all. There are massive problems with renewables. Solar panels are just 20% efficient and windmills are poorly constructed and prone to damage (especially wings/ blades). Nothing's ever perfect..

  • Have you considered making a video on biomethane as a storage option? It's being pursued actively in my home country (Denmark) as a way to use the existing gas grid as a storage option for peak load hours, that also contributes to emission reductions in agriculture. Main purpose is to use it for industry and transport - but storage option is an important secondary benefit.

  • Renewables aren't cheap because they are subsidized. Renewables are cheap because we use fossil fuel powered industries and transport to produce them. Also, i think it wouod be interesting to compare fossil and renewable subsidies with regard to how much energy they produce. Last tipe I checked, the world mainly runs on fossil fuels which means that the subsidies per kilowatt-hour are lower no? That being said, i agree renewables still are crucial to fighting climate change along with nuclear, and we really need to phase fossil fuel out of our energy production for sure.

It seems to me like these days we are all brainwashed into spending massive amounts of money on the absolute worst technologies for improving the environment rather than sound science, I mean engineering should be real science not based the New York Times and their ideas of what is best...that's a slippery slope.

  • If there was no talk of climate change wind and solar generation would still be lagging behind. It's not cheaper. If it were electric utilities would be demolishing coal plants and building towers non stop. Is it the future? Probably. Is it cheaper? No. There are huge costs. They don't last forever. And they aren't being recycled into newer wind/solar units

  • This video fails to mention the reality of hydro storage. Take Lake Shasta in northern California for example. Here you have a massive reservoir but the power house is not used for generating electricity, the dam is only used for flood control. Because it's too expensive and inefficient to turn on and off the generators as needed. Wind and solar will NEVER completely replace other forms of power generation.

  • This video makes me sad that my country, Norway, has not build more power cables to the continent. We have 87 TWh of hydro storage capacity, enough to storage all of the EU's and UK's electricity consumption for 1.6 weeks.

    Jon TingvoldJon TingvoldGiorno fa
  • What a load of cobblers. There is no scientific evidence that there is anything like a climate "crisis", intermittent, unreliable and expensive windmills lead to energy grid instability, and storage doubles the cost! To maintain reliable power that modern society needs look no further than nuclear power. Indeed, the article shows very well how expensive and impractical is weather dependent energy.

    John DowlingJohn DowlingGiorno fa
  • Pumped hydro has downsides but I'm surprised there aren't at least a couple of projects under construction in every country developing renewable energy. You mentioned using ocean water and that would be great, but from what I believe and can find, high pressure, high speed salt water is extremely corrosive.

  • Or you just build nuclear powerplants, it is cheaper more effective, less polluting (therefore less lethal), faster to implement and does not require any further improvement since the technology is already mature (no grid adaptation, no storage, etc.) If sun and wind, things that have been known and used for thousands of year were that great, I wonder why we ever felt the need to switch to fossile fuel. Where are our windmills and sun dryers we used the last two thousands years ? Yeah, reduction and nuclear. Edit : and hydro

  • I like going to the solar plants in the deserts and watch the birds fry in mid air, or sometime I go to the windmills and watch birds freaking explode as they fly into the wind mill blades. They actually call the burning birds at the solar plant streamers. Pretty funny to watch. Even watched a burning bird start a small grass fire. Smelled like bbq chicken and burnt feathers. Pretty messed up that if I point a gun at an endangered avian I go to jail, but windmills wack thousands out of the air every month, and no one says a word. The world is a comedy, love it.

  • Total fail from the get go. Who told you your "facts" about subsidies for fossil fuels? The usual green lie is to pretend that normal accounting practices allowing for capital investment to be offset against taxes is somehow a subsidy unique to the fossil fuel industry. Every industry on the planet gets the same treatment. If you aren't a baby and you grew up in the UK you would know that the revenues from North Sea oil kept the country afloat in the 1980's. It was what allowed Thatcher to smash the Trade Unions and support massive payments from the state to support the unemployed. The oil industry subsidizes governments, not the other way round. Go away and study a bit of accountancy.

Also the excavators and factories to make the green energy solar panel and turbines run on the standard grid meaning coal and fossil fuels. I don't see us running a Bagger 288 on solar energy.

Everyone knows about solar, wind and the storage problem, so why not focus on the thing that gets almost no attention but solves for most of the headaches? Seriously RE, is there a reason you shy away from Nuclear as a topic? Do you or do you not support nuclear? (SMR MSR Gen 4 etc) Do you not see that these technologies are part of the holistic future that you say is needed?

  • Nuclear as a stopgap to fusion is by far the best solution. High output, minimal impact on the surrounding environment, and doesn't require a battery that has to make up for it. The life-cycle carbon output of nuclear power is lower than solar and hydro. This technology is cool, but is unfortunately the consequence of unstable power generation.

If the renewables are truly cheaper to use than fossil fuels then we might actually have a bright future

  • I'd like to say that while renewable energy is great and all and is cheap it is not clean by any means no more than coal and I don't mean by it doesn't produce emissions it does not one of the issues is the rare earth metals that are highly toxic to humans and the environment if not handled properly we've also not really solved the end of life on these products as well they've got about a 20-year time period and most of the pieces are not recyclable either because they're too large and the example of wind turbines or the majority of the parts are just unrecyclable or unusable after that and they are toxic now I'm not saying that we should just get rid of renewables they do have their place but the fact is it goes back to the old argument the wind stops blowing and the sun stops shining so how do we take care of that well we burn fossil fuels to help pick up the slack so renewables until we have large grid power storage are not actually clean because they come with fossil fuels to help during the low times and there are some places where renewables are not realistic like the Appalachians of Kentucky there are too many mountains too many trees to reliably have any kind of renewable infrastructure that's why they've depended on coal for more than a century so what are we going to do dig up the mountains and cut down all the trees to put in more solar panels and wind farms that kind of sounds like we're doing more harm than good I'd also like to say that for solar panels it takes twice the space of a nuclear reactor to reduce the same amount of power and not as reliably when would probably be our best choice but we also need to be very careful about where we put it and how we reuse it at the end of its life

  • A great report on an exceptional, little known Irish energy solution. You are lucky that you have more mountains to carve; we in Australia did our one and only Snowy Mountains Hydro Scheme in the 1950's and have not done another one. We have lots of coal! So we have been burning it for years in various state power stations to supplement the Hydro storage created. But that only services NSW and VIC. There's 5 other states it cannot reach really, and the green movement physically stopped an ambitious Hydro project in Tasmania 30 years ago. So we have been burning dirty coal instead, for that long ; good trade off, greens!

  • Chile have similar technology, common sense said it's no the same pump water up to a hill than let it dawn. But is better than nothing. And common sense indicates that if you create a pond on the top of a mountain you damaged more the environment, only to accumulate no energy, accumulate money, the truth is the truth. Each country have own opportunities to generate clean energy, México have deserts, sun and winds, America less wind but great deserts, Europe tides and wind, but the use of any kind of energy affect the environment and create climate change, so experts think it's only another mythology issue the theme, in other hand it's no the same pollution, than efficiency, so solution is develop the technology to reduce drastically the emissions of oil and natural gas generators than prohibited their use, make them very much efficient in the use of the energy than to prohibited, latter the problem go to be battery disposal, and go to use energy, quimical energy to destroy them, and go on and go on. Better development of better electric motors, light led bulbs etc. Electric massive transports, home working.
