    Brian, can we talk about the cause and effect of CO2 and "global warming"? Are you open to discussing this with climate scientists, or is your mind closed to that assumption? If you have an open mind about the scientific method and understanding what CO2 can and can't do to earth's climate, if you're not afraid of discovering something new, let's discuss.

    Fossil fuels have a net negative subsidy, or at least petroleum (which the study linked to says dominate the subsidies) has a negative subsidy. In many countries targeted taxes on fossil fuels (gasoline taxes, carbon taxes etc.) are far larger than any reasonable measure for fossil fuel subsidies. Also your $447B/year figure for fossil fuel subsidies sound pretty fishy. You link to a 64 page PDF were you get the data but I can't find a simple list of what it calls subsidies and how much for each anywhere in the document. I've seen lists before claiming very large fossil fuel subsidies that fortunately did break down the detail about what they consider subsidies and it tends to be things like general tax deductions that are not targeted at or only available to fossil fuel producers.

    And this is why Australia was lucky that so many Irishers were damned criminals! My great....great Grandpa was sent here for forging - thanks England! Back to power. I've been converted to what I never thought I'd be - a proponent of nuclear power for the short term. We burn coal but have lots of uranium & lots of geologically stable desert. Aust needs to start nuclear power here NOW. And start a nuclear waste industry, take one for the team (world) as it were, for a reasonable price for now.

    Potential energy is not energy-dense. Look up Highview power liquid air storage. Much higher energy density with off-the-shelf components for GW and GWh at a fraction of the cost and space. Can store energy for weeks.

    Excellent presentation! For hydro storage to be practical, there must be a large surplus of electricity produced, probably 40%. That takes room. Miles upon miles would littered with windmills, uninhabitable by man and animals. There must also be hills, which some areas simply don't have. Other than that, it's fine.

    Without recognising the scale of the challenge (storage), what hope is there of meeting it? This video is an honest effort to convey these figures, so shouldn't be faulted for being the bearer of difficult news. A recent article in New Scientist reports "Green energy in them thar hills" (27 Feb, p13), and how "...each 1000 megawatts of pumped hydro could replace 750 MW of power from a nuclear plant..." - not a single mention of the amount of PH storage available from this article! The source document was commissioned by SSE (which has no nuclear) and targets EDF's proposed Hinkley Point C. It estimates a total of between 30 and 90 GWh PHS potential in Great Britain - mostly Scotland and Wales - enough to match 'Point Cs 3.2 GW baseload output for at-most 28 hours. Given the UK has a baseload (minimum continuous level) of ~40 GW in winter, and ~20 GW in summer, why not target one of its (SSEs) own gas-fired fossil plants rather than a nuclear facility which is already zero carbon? The total coal oil and gas (primary energy) consumed in the UK is equivalent to 200 GW-years per year (true in both 2018 and 2019). We cannot afford to ignore green baseload solutions on ideological grounds!

    Yeah, that's not feasible. Build like 3-4 Candu Nuclear reactors for 4.8-6.4 GW and use off peak surplus to carbon capture and synthesize petrol from atmospheric CO2. If you accept nuclear is the way forward, it can be done in under 5 years. The key is getting the anti nuclear nutters out of government that tie everything up with red tape and spread lies about how dangerous it is to scare people away from the only source of power that has a guaranteed likelihood to get us off fossil fuels.

    I will read the book. The problem thou is that when Bill Gates pushes his book now, through all of you youtubers, it becomes the truth. End of discussion. Climate change is not climate disaster. The disaster story has been pushed for half a decade now. First the ice age version then the heat wave version. Always with the "we have to do something drastic now" solution. Nothing happened and there is no catastrophe. It is almost irritating that the temperature is close to rock steady on an average. The scare and fear in people is real but the agenda is political. The book should be read with open eyes, that it is activism by the richest man on earth. The IPCC for example only exists because of an average temperature rise of the planet. If there is none, does anyone think this UN-institution will just say -O we were wrong -thanks for the attention? I hope we will be able to question and monitor their data in the future. As of now it is almost a crime to be sceptical wanting the details. My thoughts are that a healthy environment is crucial but the man made climate change is BS, that has become a religion that can't be questioned. Keep up the good work -Real Engineering.

    Hate to break it to ya, but the majority of these so called green technologies for energy generation so far create more waste and environmental damage by converting fossil fuels into their products than the actual burning of the fossil fuels themselves. Not only that, but the actual output BTU’s per unit of measure is also so far significantly worse than the direct consumption of the fuels used to make them... Ever considered this angle? DIDNT think so.

    The first minute of the video was chock full of "lying with statistics. when you talk about subsidies. Renewable receive 28% of what fossil fuels receive. Do they produce 28% of the energy we receive? The comparison should be between Terrawatts of power verse the amount of subsidy. When you claim renewables are the cheapest form of energy, you are not counting the cost of power storage in that calculation. The cost of power storage is included in fossil fuels cost. Additionally, if renewables are the cheapest energy why is Germany, the country with the most renewables, paying the highest cost for electricity in the free world.

    When I look at the size of these mega scale storage projects. I sometimes wonder if giving up on the idea of a grid that provides "base load" power is the way to go. If consumer systems were designed instead with intermittent power in mind. Storage could be forced to the edge of the grid, where power is consumed.

    I hope the obvious resources provided by tide pool generators are not overlooked... incoming tide runs through turbines, when full, the outgoing tide and draining the tide pools through the same turbine generators also generates electricity. Very large pools can be easily constructed by merely damming the opening to coves...

    From 10 to 11 minutes. Your math looks flawed? You are assuming that there must be an entire stand-by for the Max Peak, all the time? Max Peak is only a small amount of the time, and can be load-time-shifted, for a much lower peak. As more renewables come on line, the fossil supplies will become more and more surplus, as well.

    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.

    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.

    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

    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.

    Sounds like a little bit of fear porn. The planet will do what's going to do regardless what we do. It's not just the planet heating up it's the entire galaxy and no green technology is going to stop that.

    How about pumped hydro power without the pump? SEE: The World's Most Powerful Tidal Current: the Saltstraumen Maelstrom uslikes.info/house/oIl5m6yezXp5osg/video.html These can be manmade, ya know.

    Cheaper and cleaner? Lol. Just go ahead and ignore all the rear metals you are pulling out of the earth to make the solar panels and wind turbines. At least the strip mining industry will boom. 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. We just don't have the technology.

    Could you tell me what the carbon "cost" of the plant was? It would be interesting to know when it (did or) will pay back the energy used to create build, elsewise the so called "clean nuclear" solution still seems like the most logical and underutilized energy source. Perhaps you would consider a comparison video based on current knowledge.

    What happened in Texas with all their wind turbines and solar farms????

    Your calculations didn’t account for the power to pump it up as that would take more than you get out. Then you don’t just need to generate the average, you need to compensate for low wind when the power generation is really low for wind for several days

    Great video thanks. Can you do a similar video of wind to Hydrogen storage. Particularly with regards to losses and overall efficiency

    All good stuff but Nuclear Nuclear Nuclear! We need new Nuclear as a big part of the "holistic" solution. 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.

    Is it true that renewables are now cheaper to make than fossil fuels? If so then in 3rd world countries, they might use renewables as their electricity source of energy. They are still developing their economies but the problem is that they might use fossil fuels to meet their evergrowing energy demand... If the renewables are truly cheaper to use than fossil fuels then we might actually have a bright future

    I'm surprised we don't see more electrolysis as a means to store power. Converting water to hydrogen the store energy would be a great alternative to these massive construction projects, I would imagine.
