- Опубліковано 12 чер 2024
- There have been dramatic changes in some of the energy resources over the last 15 years, and even over the last 3. This video gives the latest statistics and talks about the future of energy consumption. It should be good food for thought as we enter the new decade. Happy New Year!
Can we all just take a second and appreciate how amazing it is that these fine folks make such high quality and understandable videos on these interesting topics? Big Props to both the Professor and the production team!
Hear here!
I love his Videos!
truly amazing. i wish more people watched them.
@@gabrielpalacios9023 These are great videos. Often it isn't how many viewers/listeners there are, but who they are. These type videos attract quality viewers/listeners, but not a quantity of viewers/listeners. Unfortunately, there are all of these Greta Thunbergs out there who just think they know the answer, but can't even figure out the right questions or how anything really works.
Agree
Thank you for your dispassionate, balanced, and highly informative videos. Personally, I think it’s shameful that we aren’t using more nuclear power. France gets 80% of its power from nuclear.
It does, and the state owned energy company EDF is deep in depth. Why is that? All but 3 of the french nuclear reactors are older than 20 years. I heared on this channel that nuclear power is especially lucrative over the long term.
Fission is just expensive.
agree completely
@@cavaronev4869 watch his video on economics of a nuclear fission reactor. It would be crazy not to run a reactor for longer than 20 years. you're barely paying off the initial capital costs at that point. seems like what France doing makes perfect sense actually.
@@cavaronev4869 It is. It bought France political independence for 50 years. That's priceless.
Need more nuclear plants, they are good.
Meh - expensive, not insureable by a company (the risk is with the state/the people), needs super high safety standards and skilled staff without room for human error. I take solar, wind and energy storage any time over this. South Australia is benefitting greatly from it. But I would consider the new kind of nuclear plants, which work with the nuclear waste we already have and reduce it...
@@cavaronev4869 Isn't South Australia mostly outback desert? Of course solar energy works well there. But the U.S. has a much more varied climate.
Look at 4:24 - 4:45, and 5:50 - 6:15. This is an expert in the field telling you renewables aren't going to cut it in the U.S. And if we want to get serious about lowering CO2 emissions, there really aren't other options.
@@danclassic7065 You would be right if solar energy was at the end of it's development stage, but it is still improving (as is storage). If ~20% efficiency is working in Australia now, 30% or 40% efficiency will do the trick almost anywhere. Maybe not in countries like Norway and Iceland, where it's very cold and dark for several months in winter... but wait, both are already at 99% renewables! Seems wind, water and geothermal can do the trick too.
@@cavaronev4869 Iceland and Norway both have geography that isn't present in a continent spanning nation like the U.S. They have unique geological features that make geothermal power much cheaper to produce, and a huge amount of coastline for wind farms.
So then what about a place like my Central PA? Lower than average sunshine, stable geologically, and the only decent wind is on the mountaintops, not really enough for large wind farms.
As for those efficiencies, again, that's for S. Australia. That's 20% of all solar radiation hitting the device. 20% or even 40% of sunlight on my rooftop in State College is a a lot less than the same fraction in the Outback.
@@cavaronev4869 I'm not against renewable energy at all, we absolutely should deploy it where/how it is sensible. But we also need to be realistic about how much power it can provide.
Ahhhhh, that sweet sweet sound of the marker gliding on the glass is soothing now.
I was braced for something with a political agenda, I was so pleased this turned out to be a video that just stuck to the facts rather than opinions or those videos where the facts are edited to support a predetermined conclusion.
I started seeing other energy presentations from other sources on my recommended, and they were filled with politics and “climate change” to try and get more investment. Glad to see this is something that is purely informative.
I'd love to see a total cost video per quad on each source. Cost including subsidies and total environmental cost including manufacturing and mining.
true! even more interesting: deaths per TWh...
There is no such number really. Those would be just made up PR numbers.
@@FreedomIsNotGoingToBeFree re: "There is no such number really. Those would be just made up PR numbers."
In the developed countries, those numbers (subsidies) appear in government 'budget' (and legislative bill) docs ... not-so-much in other countries ...
You’d have to factor in all the historical subsidies given to fossils and nuclear for that to make sense.
Also, the environmental cost of solar (PV and thermal) and onshore wind is still tiny compared to fossils. You have an upfront production cost and thereafter some land use (which can be diminished for both wind and solar PV by integrating them into other land uses). Doesn’t even compare to gigatons of carbon every year.
I do think developing 4th Generation nuclear is a good idea, though.
@@meh23p re: "all the historical subsidies given to fossils "
Like, uh, what? Can you give us a "program" or a congressional 'Act' or resolution name? I think you're falling back to that 'argument' that EVERYTHING gets a subsidy, which is misleading FOR THE PURPOSE OF THIS DISCUSSION.
Thank you, Professor Ruzic and the production team!
It's so cool to see University of Illinois making these videos. Illinois represent!
yeah but do you have a geothermal power plant? norcal!
In Ontario, Canada, we are something like 60% nuclear, 25% hydroelectric, and 0% coal. Except for cars, air pollution is almost non-existent here.
that's beautiful
Nuclear energy is the way off of oil,
@@kurtjohansson1265 Noticed the same thing in Paris. With their nuclear power, a city teeming with cars, the air was much cleaner.
That is only the electricity part though, not total energy.
Please keep doing what you’re doing! Love these videos!
Excellent presentation!. I think everyone should see this one.
A no- nonsense video well delivered and to the point. Excellent. Thank you.
Thank you and your team so much for these videos.
Luv facts. Ty and Happy New Year.
I absolutely love these videos. It's refreshing to see real science about energy explained in an understandable manner on the internet. I've learned a lot from these videos. Please keep them coming. And keep us updated on how that fusion technology is coming! I'm pretty excited about the future of that stuff!
Excellent! Thanks, professor!
Very fine lecture with clarity and insights, arguably better than many paid subscriptions! Carry on Energy Prof!
This Man deserve's my tuition!
Wow, one of the clearest most fascinating presentations of energy production and consumption. Had me on the edge of my seat. All I need now is some popcorn.
Iv'e learned so much fron your videos. I really appreciate the spin free presentation of facts and the incredibly simple way you discuss these complex topics.
Excellent video and excellently presented 🇺🇸
Thank you!!
The gray jacket looks good on you! Thank you for these videos. They really improve my understanding of these subjects.
Your videos are so informative and interesting to watch. You are very good at consolidating large concepts and presenting them in a manner that is easily comprehended. Thank you very much for your contributions. Greetings from a guy on a train on his way to work in Sweden.
Incredible
A fresh video with a fresh marker. 😀
I subscribed because everyone else is right- these are excellent quality videos on interesting and pertinent topics, presented in such an approachable manner, Im actually finding myself seeking out more information about them. You do your job very well, sir.
New EnergyProf content, thank you!
Last time I was this early Gore had the lead in Florida
SCOTUS: Not so fast
Never mind the actual count and 3 independent recounts that all had him losing, blame it on SCOTUS.
Guys, let it go lol
I'm really appreciating these lessons you are uploading about energy. The presentations are great and well organized and presented.
I wonder if I can ask if you can do a couple topics in the near future;
- Presentations - behind the scenes. A look at how your setup operates with your screen and your slides that you present
- Comparison of Nuclear vs renewables. A look at the numbers of RoI, energy density, running costs, life expectancy, end of life decommissioning, etc.
I did find your "There's Always a Cost" video, which was helpful, but if can done for the major energy sources it would be very helpful.
Love your videos!
2 significant improvement suggestions to this video 1) also show energy usage by capita next to those numbers, this is very relevant information 2) also show a pie-chart of each county's energy production split then and before.
With these changes, this video would skyrocket in informative value for the uneducated
yes, like civil and business. say would be interesting to compare industrial and civil consumption in china and us. also shipping from china to us, who carries the burden?
Energy use per capita isn't particularly useful. Here in Canada, for example, our per capita usage is very high, not because we are particularly wasteful but because we have to heat our houses at -40.
Long term nationwide usage is more relevant to the discussion.
@@TheOwenMajor You don't seem to understand the matter at hand at all, so I won't bother trying to explain it to you
@@Songfugel You really do come off as a massive ass whole.
@@TheOwenMajor Maybe, still beats wasting anymore of my time on you
Great content and production quality (I do miss the squeaky markers though :-)
A little suggestion - if you put the monitor on the other side then when pointing at the projected (superimposed actually) graphs and figures then it would appear as if you were looking directly at the image.
Constantly impressed with this guy's ability to write in mid-air. Astonishing!
hehe the secret is he writes normally, but they mirror the video so the writing is reversed.
The addition of the global population in each column would have been helpful in figuring out per person usage. Excellent series, BTW. Please don't stop making them!
I stole the professor's squeaky markers. Arrrr, me hearties!
I remember taking NPRE101 (which he sadly doesn't teach anymore) a couple years ago while I was still in school. I only really took it to satisfy some geneds.
He was one of the best professors I had, the most fun I'd ever had listening to in lecture (though I didn't like the assignments!). Really helped me understand so much more about the world of energy, even though it wasn't my major.
Hope you teach the class again some day! The lecture where you swam in Bonecreek was the best :)
Great stuff, thank you. I more the squeeky markers
Good stuff as usual. Could you turn up the volume. All of the other shows I watch much louder.
The presentation is good, the information is interesting. I don’t understand why the thumbs down ratings....
Because the Left hates reality.
When you tell them nuclear is a good thing they do get defensive....
Professor Ruzic,
UA-cam question: What is your opinion on the Molten Salt cooled Nuclear Reactor,
Is it an option and could it increase safety margins ?
Thank you.
Nice information. What's the current state of space based energy development?
thanks for such organized analysis!
Some remarks from me:
- gas got more popular in the US because of many shale gas extractions which appeared only during such timeline used during such analysis
- perhaps India has so relatively small energy consumption (compared to China) due to the country is in warm climate (not sure which part of the produced total energy is dedicated to heating and related service)
Please have older years on left and more recent years on right like standard timelines. Great video as always!!
Could you please do an economic cost of energy by type? Ex. Total of a coal plant plus fuel cost / BTUs produced over its lifetime?
Check out “economics of nuclear power”. Not everything you want but closer
The term for what I think you're looking for is "Levelized Cost of Energy" (LCoE). One of the most prominent LCoE assessments is done by the financial company "Lazard", and is updated annually (usually in November I think). It's freely available online.
Can you increase the volume gain on these videos? My mobile is turned up to max and it's still not loud enough. Other than that I really appreciate this series.
What are the projections for frack oil wells yet to be installed and depletion rates over time? I mean our frontier zones are limited. Also so is the 10 million gallons of water plus used per frack.
this videos are epic!
i‘m glued to the screen, even moore due the covid time.
in switzerland were i live, we sadly wave goodbye for future nuclear power plants.and those who are still in service ( 4 of them) give us 35 % electric power.
do the math when 2040 all are shut down..
anyway, thank you so much energy prof and your team.
Thank you for this video. Could you please talk about energy subsidies in a future video? It would be interesting to compare each energy source's production by the amount of taxpayer funding they receive, along with the growth of those energy sources and subsidies over the years.
Can you do a video on the integral fast reactor?
Isn't it that consumption in the US is flat just because much of the industry was moved to China?
Maybe of interest, though slightly outdated: www.carbontrust.com/media/38075/ctc795-international-carbon-flows-global-flows.pdf
He mentions this, still the GDP continued to grow as the economy transitioned
4:38 I say opinion! Because there is no physical reason why it should not be possible. We need a lot of energy storage though (electric, heat, kinetic - maybe power-to-gas).
Cavaron EV Tesla is here to stay
Maybe but all these additional storage systems make it less economically competitive especially with redundancy and seasonal variation compared to electricity on demand/ base loading plants
Happy New Year! can you revisit your global warming lecture this year? I thought the old one was somewhat superficial and left some things open to misinterpretation (out of character for the rest if this channel). maybe you can really clarify a well formed position in an updated way now. appreciate the nice clear content otherwise. Thanks.
The new non-squeaky markers are way cool :)
Love your videos, but allow me to make a small correction the generic formula for coal is C(x). For oil the formula is CH(x).
Great videos. Getting slightly outdated, which is understandable. As of 2022, solar was already up to 3.5% and wind 10%, and the adoption of solar in particular is accelerating as it becomes ever cheaper.
Volume seems a bit low on this one.
Thank you for this interesting analysis. The one thing I (as an European citizen) I do not agree on is that we perform great because our graph is rather flat. This is a misconception as we do NOT produce as much stuff as in earlier decades, but rather let China, ... produce lots of our stuff. This explains a big part of the rising energy consumption in those countries (which actually relates to our wealth > thus should add up in our numbers).
very good thanks. Incredible that the common conception on the street is that fossil fuel use is declining and is yesterday's energy to be displaced by solar and wind. People actually take that as a "given"
Professor in your opinion what energy source or sources should the country concentrate on and why?
Great video. Don't underestimate solar, it can not do everything but it is really taking off, lets check in five years. Also if we can develop large commercial air conditioners that can store energy during the solar window (11 am - 5 pm) and just use the fan at night, that will help. Electric cars give us maximum flexibility on energy use and are more efficient than gas.
I'd like to see a lecture on the energy costs of transportation systems. Mazda says diesels are "cleaner/greener" than electric vehicles. Humvee claims it's more energy efficient than a Prius when you take longevity and resource extraction and manufacturing into account. I'm hoping Energy Prof can shed some light on this complex topic.
Im glad to see Boromir doing well after LOTR
Can anyone please tell me what the control system tank is on an rbmk? I can't get a consistent answer from anyone. And I was interested before chernobyl (HBO) just fyi. I was born in Europe in July 86 so it I've always been interested!
This video needs 350 million views. There's too much political conjecture (from both sides) that needs to be reinterpreted and made accordant with this essential info.
This is the best channel regarding science on UA-cam. Thank you for your efforts!
I’d love to see a video, or series of videos, on real solutions. How to provide the energy required to provide a good standard of living for all people. What will it take? What are the options? You seem to be a trustworthy source of information...
Thank you for pointing out we can not replace oil, gas, coal and nuclear with intermittent energy. It’s not a problem to solved with technology, but understanding energy density and baseload power. Mathematically it is impossible to move to less dense energy sources and solve it with volume, you can try but it is madness. California a case of moving to intermittent energy, with a shell game to buy energy oil, gas, coal and nuclear from surrounding states. When you buy from other states it has to travel the grid and significant energy is lost as it travels. Balancing a grid is not a shell game you will win.
What we need is conservation. It's not that dirty of a word. Winter has set in where I live. I have my thermostat turned down a bit. My gas bill is cheaper. I'm happy.
How much energy was saved by switching to non-squeak markers?
So how are the plants now going to get their CO2?
Interesting review! Can a flat energy consumption be explained by flat level of energy hungry manufacturing? To do "more" US may import heavy manufacturing components thus needs less energy.
Steel was 6 percent of US energy now 2. So China subsidizing to get most steel work helps.
Would be interested in a video of how new efficient technologies will/are affecting these trends. When the US was going through this growth spurt it was done with incandescent lights, inefficient electric motors, computers that required refrigeration, and poorer or no insulation....etc. Would love to see if these improved technological starting points are showing up in the data as other countries start ramping up.
Do you have the stats for state by state? Also how much is exported?
State by state information is a bit harder to find. More videos in the future may discuss exports and the like, though the amount pf energy export for the U.S. is typically fairly low.
Here is a good article on energy use from WP
www.washingtonpost.com/graphics/national/power-plants/?.880d55c1e385
The UK would beg to differ on if you can replace hydrocarbons with renewables. We’re currently are about 47% electric from renewables. We’re also working on storage rapidly.
I've watched way too many of these videos.. Its a testament to how good this content is that somehow a series of topics I've either had zero interest in or never had it even occur to me to consider I've been so engrossed with.
Same here, it's really great to find interest in topics like this all thanks to the great presentation skills on show.
Please, pretty please, and quadruple pretty please do a presentation on the impact of electric vehicles on the U.S. electrical grid, with analysis of renewables and how they will or will not cover the increase of demand on the grid. Folks need enlightenment on this issue, and I foresee trouble ahead, caused by magical thinking..... am i wrong?
Love your vids, keep up the good work!
If EVs are going to take off (and it sure looks like they will), we will start to see a reduction in "oil" quads and there will be an increase in "electricity" quads.
However, while EVs are near 100% efficient with electricity, ICE vehicles are only about 20-25% efficient with oil.
So the "oil" quads are not the same as the "electricity" quads generated by renewables
Electricity is much more "valuable" energy than oil or coal or natural gas. (and this crucial difference between the various energy sources is something that is missing from this video).
Oil use is huge in the US, and it may seem that the electric grid would go down if we all move to EVs. But because of the efficiency difference, it's not going to be so bad. Look at this (overall US energy use) graph :
flowcharts.llnl.gov/content/energy/energy_archive/energy_flow_2011/LLNLUSEnergy2011.png
Notice that 25 quads of "oil" energy go into the transportation sector, but only 6.76 quads are used for actually moving vehicles. That's the ICE (Internal Combustion Engine) in-efficiency right there.
If we would move to EVs, then we only need to provide that 6.76 quads (plus some charging losses etc) in the form of electricity, which is about a 60% increase of the 12 quads that the US grid is currently providing.
So, yes, if we move the entire US transportation sector to Electric Vehicles, we will save 25 quads of "oil" energy, and it will cause a 60% increase in load on the US grid.
That's manageable. We just need some semi-smart grid where we don't charge all electric vehicles at the same time.
Currently, not an issue, don't see it being an issue for the foreseeable future. I don't see the ability for EV's to be more than a rich people's toy even with expanding supply networks(excluding potential small city vehicles). If anything more load during the night(charging) will help balence demand out a little.
@@2meters2 not sure where you live but in Europe, our (modern) cars are more efficient than 20-25% I believe.
We have really small, high torque turbo engines. Not an expert tho!
And are EV's really anywhere near 100% efficient taking into account rolling resistance, aerodynamic drag, battery degradation, moving parts (albeit less than in ICE) but things like differentials etc?
@@Ryan-lk4pu ICE are about 33% efficient. Electric motors are 90% efficient, so whatever other forces are at play, aerodynamic drag, differentials etc. EV's will always be way more efficient. Yes we will need to produce more power, buy electric energy can be produced from zero CO2 sources, and low CO2 sources. Natural gas produces way less CO2 than coal.
Two things, electric motors are 90% efficient, ICE are 33%. Second, you can create electrical energy from many sources, nuclear, natural gas, renewables, all produce far less CO2, than an ICE burning gasoline. Yes widespread adoption of EV's will require more power, but the power can be made in a less CO2 intensive manner, and be used more efficiently by an EV.
How do fracking and coal compare when taking the whole extraction-to-consumption chain into account?
Coal preparation isn't very energy intensive. It's really just sizing and washing
With fracking you are using pressure or column pressure to liquefy gas. Butane or methane liquefies about 150 psi at room temperature according to Gay Lussics law. So you are using gravity to do the pressure work for you to liquefy gas. So at 33feet you have one atmosphere with 14.7psi salt water, freshwater 14.1psi. Now you can increase that atmosphere by adding more salt through salinity in your water column to liquefy methane gas. Hope this helps.
Ye boi first
That title, Then and Now, Here and There, still makes me sad. Great lecture nonetheless.
#MakeMarkersSquealAgain
Love the video but your chart at 8 min doesn't match your chart in the beginning? In your 8 min chart your renewables passed nuclear.
0:49 I prepered my ears and.... suprise!!!!! So chinese torture sound hahaha
There are two significant geothermal power plants in central Utah, Blundell and Sulphurdale.
Here in New Zealand we have shut down several major power stations and haven't run out of power, so I'd have to assume that we have massively reduced consumption.
Nope, you are flat like the rest of the world. I see coal has reduced but been replaced by oil and natural gas.
Wow enlightening and depressing how little progress we made and how world is getting worse. We better get moving on science fast to get us out of this mess.
I did a project on Geothermal Generators recently, maybe you should look into Enhanced Geothermal Systems, or EGS.
Thanks for that, encouraging. Texas is experimenting with a couple Tesla towers and thorium reactors are in view for power production as well. I think India is pushing that.
Can you also post CO2 output equivalents by year for US and for the world by country? Do you have data on the breakdown in China, for example? That would be interesting data.
geothermal energy production should be much higher. Unlike wind and sun, you can produce energy 24/7. Wind and sun energy need to be stored in batteries to be used at night and when there is no wind. There is also enough geothermal energy on the west coast to power the whole nation many times over.
Move your graphics monitor to the other side of the camera so you wont be looking in the opposite direction when referencing graphics on the screen.
Who else here was totally surprised that "renewable energy" was even on the first part of the chart?
5:56 I hope you are wrong. I think there is a huge growth potential simply through cheaper wind and solar even without cheaper storage (note you don't have use all you produce during peak supply, also variable pricing will allow demand to adapt to supply). If both renewables and storage get cheaper (which they are and fast) then the change in renewables can be huge.
Add also cheaper chemical long term storage (weeks and months) and or improved global energy grid to absorb national fluctuations and sky is the limit!
What are the facts behind SolarReserve’s Crescent Dunes backed Citigroup and US Dept of Energy ?
I'm studying chemical engineering in the UK. It is frowned upon to use BTUs even in Britain lmao.
I gotta be honest with you, I miss the squeak. (Still great content though)
Perhaps shifting of manufacturing activities to Asia had something to do with the leveling of the energy use in USA.
Definitely contributed, but many of the industries that have grown in place of manufacturing require lots of energy as well. The energy consumption of servers (like the ones allowing us to have this conversation) is very high.
Since the marker change my cat finds your videos less interesting ;)
This shows why electrification is important. Electric motors, boilers etc. are all more energy efficient than their fuel-burning counterparts. And although that means a lot more electricity generation will be needed, the US has a vast potential for renewables given its enormous landmass. There is a lot more that can be done right now, in many parts of the world, even if we don’t yet have the nuclear and biofuels to replace fossils.
Gas transportation is also cheaper and safer, via gas pipeline.
