  • I'd like to ask for some clarity on the energy subsidy data. While $447B is approximately 3.5 times the $128B, fossil fuels still make up 80% of global electricity generation while fossil fuels are roughly 5%. Per percentage of energy generated fossil fuels would cost $5.58B while the same energy percentage in renewables would cost $25.6B. Is the chart total subsidies or per unit of energy generated?

    • @Zuurker U Nope, the problem with both is that they depend on it being daylight for solar, and windy for wind power. Hydro and Nuclear are by far the best we have right now as they both provide constant dependable power. If some form of solar reflector system were to be built in space to get around the problem of not getting solar power during the night that could be fixed but not in a decentralized manner, but we don't have that made right now. Germany and some other European countries have invested heavily in wind and solar, and now have an inverse issue whereby they export power almost for free during the day but have to buy it during the night and on overcast days with too little or too much wind (wind power only work when there is a set amount of wind speed, too much or too little means no power). Another possibility would be to use large amounts of batteries which is being tried in some places but that has other issues aside from cost, the battery technology is "dirty", uses rare earth minerals that are difficult to extract and refine and that process itself is very polluting right now and controlled almost completely by China. So, at this moment my statement is still true, but in the future we could find ways to fix the problems that solar and wind have, but we do not have a really good solution for the problems right now.

    • @noth606 No, bud xD Wind and solar could easily power the grid if enough investments were made... Though, it might not be a good Investments it can still be done. Solar and wind are the "best" electricity generating sources now because they succeed where every other producer fails, they decentralize the energy grid.

  • Not just one solution. Yes there is. Ten or so SMR's available 24/7/365 Two in each of the old peat stations for starters. Next to them using much of the power, again 24/7/365, big data centres each using a couple of hundred MW of power. Then using the waste heat of these and the SMRs a vast area of 24/7/365 LED lit, hydroponic grow houses for salads, vegetables, cut flowers, avocados and G God knows what else. Then next to them the Soldier Fly farms, the larvae eating the processing wastes and also much of our one million tonnes of food waste a year here in Ireland alone. Then the fish farms and the chicken, both at present two of the most horrific environmental scandals on this planet. Then the rest of the bog areas for carbon, phosphate and nitrate sequestration. How criminally stupid we have been to put all our eggs in the wind basket, making billions for our home grown Oligarchs who have now sold out the real pushers behind the scene, the fossil fuel corporates, eager to have us over the metaphorical oil barrel for filling in the big gaps, not twelve hours, but with a winter blocking high, potentially two or three weeks, like in Nov / Dec 2011.

  • A brief on Hydroelectric 2 nd stage power recovery system This system is for all hydro systems running with a TAILRACE setup Why a tailrace setup ? In an ideal setup without the need to modify the construction plans to fit into a geological or given plot of stable ground, the benefits are not lost to compromise. As however in the real world hydroelectric systems are generally a compromise, and the TAILRACE is invariably longer than the turbine hall would find IDEAL in regards to power made per ton of water used - a loss that can now be recovered With the turbine hall believing a shortened tailrace has been fitted this allows the turbine hall to make more power out of the same volume of water IT IS WISE TO NOTE TOO SHORT A TAILRACE AND A SURGING ISSUE OF THE TURBINES WILL OCCUR, leading to its self destruction What sets how short the tailrace can be made? Because each and every dam is in effect a custo- made system, and so the type and number of turbines at the location dictate the power recovery units location in the tailrace But there are basics that are common to all hydro installations Example of why a shortened tail race works A different way to look at what is happening at this point is: You buy a 2 stroke motor to fit to a go-cart but it needs a bit more power. The quickest and cheapest way is to get a tuned exhaust pipe - it’s generally a shorter and larger pipe This allows the motor to breathe freely and returns a boost in power output with just the right amount of back pressure Firstly Back Pressure This new setup will not generate a backpressure issue to the dam (a common reason why to date the industry has failed to benefit in this area). In short blinded by their education. A stumbling block that has been drummed into every Engineer so no one looks at this sort of issue as solvable Secondly Down Time The assumption is made that to build this system would mean the dam will be offline for years when 90% if not more of the installation will not require the dam to shut down and the final step can be taken during the annual servicing period of the dam The freeing- up of the turbine hall from having to work with a tailrace that is now tuned to the best power output. NOT distance to the discharge point! And along with my new 2 nd stage turbine power recovery systems the return should be 3- 8% more annually combined Thirdly Servicing With no extra shutdown periods needed to service the new power recovery system as this can happen independently And should a unit go offline in say a three-unit setup, the offline unit can be swapped in a day without the need for the remaining two units being effected OR the turbine hall operations The end of the tailrace will continue to spill out into the existing lake or river location with only one extra outlet fitted to handle the same water volume, but now at a slower pace so that all works are easily able to be environmentally completed If a pump hydro system is used this will not alter the setup or require modification It should be noted that this system has less parts to an equivalent turbine setup so there are less failure points And is expected to outlast the required life expectance of the dam NOTE Chinas hydro output to date is: According to IHA's 2020 Hydropower Status Report, total hydropower capacity reached 356 GiggaWatts in 2019 after a further 4.2 GW in capacity was added China's total estimated hydropower generation reached 1,302.00 TerraWatt hours. FINAL POINTS So say China’s hydro output was up by a further 3% only (as not all China’s dams can run this system). So what is that worth as annual income to the country? It should also be noted that a new dam construction with a penstock hydro system fitted will double the return in secondary power recovered and still be serviceable without impacting the turbine halls operations simon bowman rdp marine facebook

  • Come on. You know better than to say that renewable is less subsidized than fossil. Fossil fuel still provides the vast majority of energy production. In dollar per killowatt, subsidies are much higher for renewables. From an immediate economic outlook fossil fuels are still far cheaper. Hydro is the exception, it is cheaper than fossil fuel, but environmentalists block almost all new dam construction. Only if you account for the damage caused by fossil fuels do solar and wind become extremely attractive. I don't hate renewable power, in fact I have loved solar from an early age. I plan on going off grid with renewables. I just don't like dishonesty.

  • @RealEngineering Just a question... If the draw of power to pump the water back up to the top is bugger all, then why couldn't you put an extra turbine to directly power to the pump so it's filling up as its producing electricity? Or run something like a dynamo off the turbine shafts ? Anyway just wondering? Excellent work, Interesting, informative , and unbiased and balanced.

  • Although a good video it is still looking at the issue from a centralized power grid. The Australian National University in partnership with Engineers Australia did a preliminary study that identified tens of thousands of locations where small/medium scale pumped hydro schemes could be established. This fits in with distributed power grid architecture where the energy is generated close to the load (and obviously stored there as well). This is in Australia, the driest continent on the planet! The Australian Government, of course (being backward as usual and liking flashy announcements) decided to extend the Snowy Mountain Hydro Scheme with all of the issues listed in this video. As a minor point, the term power generation is fine but when you are talking about generating AC the device is an alternator, a generator is used for DC. In many respects DC generators have advantages over AC alternators courtesy of modern technology, so they many indeed be generators in the future. >>;-)>

  • Everyone is always talking about hydrogen for long term storage and the automotive industry, but methane arguably just as appealing. This might be because methane is more commonly associated with natural gas, which is not an energy storage medium, but it can be used in the same role as hydrogen in power-to-gas nonetheless. Methane has a lower conversion efficiency to hydrogen, and the process is more complicated and costly than for hydrogen. That being said, methane can make use of existing natural gas infrastructure, which could help to reduce costs.

  • While I agree that fossil fuels are a convenient but very messy and pollution ridden way of getting energy, I also disagree with this perspective as it is presented. The advancement of technology that has been based upon traditional means of power generation allows us to actually provide a vast array of 'bespoke' solutions according to the given environment involved. (Obviously low wet flat lands, differ from deserts which differ from mountain ranges, or jungles etc.) Also since truly effective alternative means of mass energy production can never (and will never) be discussed here, it's a disingenuous to simply present such a simplistic overview of the (utterly man made) problems we face in energy generation and distribution. (i.e. Solar and wind good, fossil bad)

Which means we need to rely on other countries to "take care" of our nuclear waste. There is no perfect solution.

      golangolan11 dager siden
    • @golan Yes, when the level of the reservoir gets lower you'd need more flow for the same output since the pressure/force decreases. Usually pumphouses are located further downstream instead of at the bottom of the dam to reduce this effect. At a place from my youth in Austria the dam started at 1300m above sea lvl but the pump house was 15-25 km away at 880m above sea lvl

  • sorry sir, but your comment about cost is incorrect as you have to look at cost per megawatt-hour to find the cheapest. The cheapest type of generator is the combined cycle combustion turbine (natural gas, very clean almost no pollution) but i digress..... Offshore Wind = 89.2, Battery storage = 57.98, Advanced Nuclear = 50.51, Ultra-supercritical coal = 43.8, Hydro = 38.62, Biomass 34.96, Onshore Wind = 27.01, Solar = 23.52, Geothermal = 19.03 and Combined Cycle = 7.78 (All figures are US Dollar per megawatt-hour for capital costs). • U.S. levelized capital costs by energy source 2026 | Statista Also, for a national grid you much have MVAR (voltage) support to be able to "push" the AC power through your grid. Solar gives absolutely NO support via MVAR's and most wind farms do not (they can but most do not) provide MVAR support either. There are many other factors you have not informed your audience and that's wrong! Not in our generation will we see wind and solar to even be a significant portion of any national grid of any size. Not right or wrong but real figures and facts you have conveniently overlooked.

  • In the areas with water shortages use compressed air, as compressing air pulls moisture from the atmosphere. Thus why air compressors have air dryer units to keep them from rusting out. The Amish in US are currently using old propane tanks for low pressure compressed air storage. The missile system adjacent to the radar system I worked on in the 1980's had a 10,000 psi dud ejector so it might be a good model and the most efficient air compressors are axial flow at north of 90%.

But actually, a hydro-pump is nothing more than a HUGE rechargeable "battery" that has to be charged if it is to supply power to the grid. That power has to come from somewhere and be powered by something. Just exactly what are you planning to use to charge these hydro-pumps? Then how does that benefit the environment if you still have to have a power plant to supply power? The world wonders.

  • The mother of all pumped hydro projects could be Lake Erie being the upper reservoir and Lake Ontario the lower reservoir. A canal could be built from near Crystal Beach Ontario to the hydro canal for the Sir Adam Beck Hydro station in Niagara Falls Ont. where generation and pumping would occur. A weir across the Niagara River would control Lake Erie's level which would also solve storm damage to Lake Erie homes and cottages. I did a quick calculation and found for every inch of water level on Lake Erie's 25,750 km2 of Lake Erie, it holds 643,750,000,000 L of water that can fall about 70 m overs Niagara Falls. Assuming a 10 % head loss and a 15% generation loss, I get 100 GWh of energy storage per inch of Lake Erie height. This could provide diurnal, and multi day energy storage for the states of Michigan, Ohio, Pennsylvania and New York and the Province of Ontario whose combined populations are 68,000,000 people.

  • What?... Correction, 1m3 water with 1m drop, has 2.7kWh, not 2.7wh

  • wouldnt pumping the water up the mountain use as much energy as you would get from dropping it down again???

  • Here is an idea. Over the Rockies pumped storage in the United States, joining the Mississippi and the Colorado Rivers across the Continental Divide. Using excess wind and solar power to pump Mississippi River water to a huge reservoir in the Rockies, and then release it on the western side through generators capturing that power back. If done on a large enough scale, it would also solve the Water Crisis in the west and reduce Mississippi flooding in the east.

  • No, 'fossil' fuels have NOT been getting more subsidy; they're TAXED and REGULATED. That money is where renewables' money comes from. After that, ratepayers get gouged to pick up the rest. There is NOTHING so-called renewables do better OR cheaper. All forms of so-called 'energy storage' are bandaids to try and get pinwheels and smoke-and-mirror solar to work

  • I read Bill Gate's book. I don't understand why @Real Engineering say's we need a mix @15:30 of batteries (and/or power generation methods). I've heard this idea of a 'mix' around a lot before. You can run a grid on 100% Nuclear right? Bill really perplexes me. He allocates a little of the book discussing Nuclear and how undervalued it is, basically describes it as the holy grail. It has none of the down sides of renewables and it's safe. But, the weird thing is he doesn't say why we shouldn't just run the grid/s on pure nuclear. Sometimes I wonder if it's because he knows that it just FEELS too scary for humanity (as a whole) to accept?

  • Pretty excited to find out that there's a closed-loop pumped hydro project being planned two hours East of Portland, Oregon along the Columbia River Valley. It's called the "Goldendale Energy Storage" project.

  • Has anyone actually crunched the numbers on Wind Power? Iron ore goes from Aus -> China Turned into Steel Tower sections are manufactured in China/Abroad Blade sections are manufactured in China/Abroad These then get shipped across the world. So it's manufactured in a place that is known for having shit Environmental protections/controls and is mostly powered by dirty coal. Then it's all shipped across the planet on vessels that are notoriously dirty and run off gross bunker fuel. Towers have a lifespan of ~20 years. The blades need to be replaced whenever they are struck by lightning. The blades aren't recyclable and are made of fibreglass. Every time a blade needs to be changed, a large crane is needed to be moved in (And all the work that goes with that, road works etc) And when there is not enough wind they don't work and when there is too much wind they don't work. They also need de-icing if in a cold environment.
