    Do we need nuclear energy to stop climate change? More and more voices from science, environmental activists and the press have been saying so in recent years - but this comes as a shock to those who are fighting against nuclear energy and the problems that come with it. So who is right? Well - it is complicated.

I have a profound respect for Kurzgesagt. They put an enormous amount of time into research and animating their videos, try to make scientific topics as simple to understand as possible, and treat their viewers with a lot of respect. The Earth mug I bought from them hasn't had any paint come off even though I've been dishwashing it for a year, definitely not a cheap product. Of all the YouTube merch I've gotten, I think theirs is the highest quality (just barely beating out LTT). They could have just kept with patreon alone or gone with a cheaper producer, but they genuinely care. I'm happy that there are actually content producers who just want to educate the world and make the world better. As soon as I get a paycheck I am going to put a good amount of money into their patreon per month.

@Crygear By 1986, nuclear power was a pretty mature technology and well-understood (at least what we need to do to keep nuclear power generation safe). Chernobyl was a disaster waiting to happen. The techs told the manager that the way he wanted to run the test. He bullied them into doing the test and the rest is history. Add to that shoddy Soviet engineering and construction and it's a miracle the disaster didn't happen sooner.

I always bring that up to people when talking about renewables like wind or solar is reliability, especially in regards to solar energy. Winter is when people would need that energy the most to heat their homes. I live in Wisconsin. During the prime winter months, we only get about 9-10 hours of daylight if we're lucky. What's more, it tends to be very overcast during winter here so a decent chunk of that sunlight isn't even getting through. Winter is a tough time for a solar here. So then there's wind. That brings its own problems, especially during winter where snow and ice storms are notorious for knocking out wind turbines, right when people need them the most.

Nuclear energy was a legitimate threat to the fossil fuel industry so companies campaigned hard to make it look like the most horrible thing ever, taking advantage of the fact that the most common nuclear reactor designs produce materials that can be used to make nuclear weapons. Combine that with what happened at Chernobyl and it wasn't very difficult to convince the population that nuclear energy is too dangerous. Younger generations are more willing to give nuclear energy a chance, but the older generations which lived through the Cold War are still clinging to the idea that nuclear must be avoided at all costs.

The short answer is basically, yes, the only way we can reduce our carbon emissions is to either stop burning the fuel sources we already use, or use vastly more efficient energy dense fuel sources currently available, nuclear is by very far the best option, if you care about the planet, the climate and the human species, you need to support nuclear energy.

As a scientist who studies this kind of thing, this is really well explained! I have a similar opinion to you, and many of the scientists in my lab do as well. If we are going to start to fix climate change for real, we need to use everything we have. On the actual facts, I might start using this video to teach my students, as It's really hard to explain this issue and this video does it really well!

โ€‹@Adin P (polite discourse) The cost of solar is higher than people claim. You can't put solar panels anywhere if you don't have land to put them on (including roofs). Part of the cost of nuclear is buying the land and performing environmental impact studies, talking with the public, etc. And plants are built to be unique rather than using the same design. Cookie cutter houses are cheaper because they use the same design. I think even solar farms are more expensive. Ivanpah cost $2.38 billion in 2019 dollars and has a nameplate capacity of 392 MW. This comes to $6,071,428.57/mw. San Onofre cost $10.9 billion in 2019 dollars, had a nameplate of 2710 MW, coming to $4,022,140.22. Ivanpah began construction 27 October 2010, commission date 13 February 2014 ("Or 3 years, 3 months, 18 days including the end date"). San Onofre's first reactor (456mwe), construction began August 1964, commissioned January 1, 1968 ("Or 3 years, 5 months, 1 day including the end date.". The other two were commissioned in 1983 and 1984 but had protests starting in 1977. Not many protest solar farms but if they do it's for different reasons than nuclear. People protest nuclear because "it's deadly". People protest solar because they don't want forests cut down or cemeteries desecrated). In the end with everything being equal, nuclear seems less expensive and for the same output gets built faster (the cost would increase for solar to be built faster). Wouldn't a nuclear plant surpass the 1mw solar farm in days not months? If the farm produces electricity 8 hrs/day 365/yr, for 5 yrs that would be 14600 mwh. A 1000 mw nuclear plant would produce 12000 mwh in 12 hrs (smaller plants can be built faster and would still beat solar. A 200 mw reactor would produce 14400 mwh in 3 days). Wind isn't that environmentally friendly. The blades need to be durable which means they're very difficult to recycle (not reuse). They're made with plastic which gets scattered around the world because of erosion (plastic straws are bad but not blades). They disrupt air currents which affect the rest of the planet. And they kill birds (which means those who would have eaten the birds or what the birds would have eaten are affected). Hydro is better than wind because people have been changing landscapes for thousands of years. And people need to get drinking water from somewhere. The Great Lakes are one example of being hydroelectric and tap water (and recreational). And which is better, taking tap water from rivers and oceans and dumping filtered waste water back into them or having a reservoir where it's an endless cycle of hydro+tap (toilet to tap provides clean drinking water and if it's good enough to be dumped for fish then wouldn't it be good enough for people). Many nuclear plants have "private" lakes which are used for hydro (Arkansas Nuclear One uses Lake Dardanelle as its cooling source. Wikipedia lists Lake Dardanelle as having a nameplate capacity of 140 MW and a 2019 net generation (MWh) of 594,423, producing the 2nd most from hydro). Other than energy what does wind provide which make it superior to hydro (land use for hydro is debatable. If there weren't a dam/lake there it would be some sort of real estate. Land is needed for wind). Some claim wind helps farms because of circulation but at the same time it makes it harder to spray pesticides along with a few other problems.

@ใ„ใ‹ใ most modern nuclear reactors can run safely until they are out of fuel with no user input. In the event of an error, every known mode of failure is safe. That is, it is far far more likely for an unmonitored plant that undergoes a failure to undergo it in such a way that the reactor is rendered incapable of reacting before damage is done to the outside world. Think of a modern car engine. Smash it up in an accident and 99.999% of the time it just stops running, because it is designed in such a way that its preferred ways of crumpling isolate the fuel from any potential ignition sources. Burning is rare, and explosions in modern cars are unheard of. Technically possible, but excessively unlikely. Nuclear also produces less waste heat per MW than any other form of energy generation 'mikey' above is just ignorant. The potential thermal efficiency of a powerplant is determined primarily by the core temperature and pressure. More pressure and temperature in the core is good. Less in the environment is good. All plants have an environment equal to 1 atm and whatever temperature the weather is at. Nuclear plants can run at higher temperatures, so can use a smaller core to generate more energy. (Think of trying to spin a wheel with either a candle or a blowtorch. To get the same speed with the cooler, more dispersive candle you need a REALLY big candle that will heat up the whole room very fast.)

@Mark Hackett My point was not the numbers, thatโ€™s why I said it may not be completely accurate. The solar farm one is quite accurate as they can cost anywhere from 800k to 1.3 million dollars. My point is that even though Nuclear facilities do cost a lot more in construction and maintenance, they are more efficient in making power with a less amount of space.

nuclear is definetly a requirement for the future. if we just spent 10 years on making reliable reactors that aren't 50 years old, they can consistently produce a silly amount of energy. Thorium reactors have a ton of potential, while also allowing countries to go nuclear without being denounced for the possible nuclear armament. In your other episodes, you talked about other reactors and some that use the type of fusion our sun uses to make energy. Nuclear will provide the needed energy for the dyson swarm, and once we get that up and running we're fine on the energy perspective.

โ€‹@Googlar I'm working in the energy-transition nowadays, and I do actually blame politicians and academia too, for their ideological purity. What you see is that people have strong opinions on energy, oversimplified: left is against nuclear, right is against solar/wind. No-one wants to compromise. This also leads to horrific renewable-energy-laws, that my collegues and I have to work with. For example: it takes *10* years to build a renewable project here in the Netherlands. 2 years construction, 8 years for NIMBY-procedural BS. Every person living withing 400 meters of a solar panel is a stakeholder that can veto it. Thus, our representatives have really dropped the ball on everything energy-related. I hope more energy-experts will seek office, cuz this is unsustainable.

It's mainstream political parties who have failed to properly appreciate the value of nuclear power. Don't blame green parties for something which they never had the power to stop. Maybe some green party politicians played a small part toward contributing to reduced investment in nuclear power in one or two European countries, as a part of a parliamentary vote. Not all "green" politicians are anti-nuclear, and green party politicians still have better than average views on the importance of managing environmental costs in industrial and economic regulations. All political parties have ignorant supporters among their members, and have made bad policy decisions. Don't blame a minority for something that they're not even responsible for.

@John The bit that gets me is the logic trap; If the politicians are not knowledgeable about the subject matter, and the people voting to elect said politicians are not knowledgeable about the subject matter... you see where i'm going with this? I feel like the main thing that would help in the long run is having peer reviewed Scientists take over the school curriculum needs of our education department, take politics Out of it, and actually teach critical thinking skills and the scientific process to kids, instead of churning out our good little worker bee's... maybe that would help? I don't know. I'm an old man, and I've had maybe 50 teachers in my lifetime so far, and out of those, maybe 3 that actually put in the effort and inspired me to Care about the subject matters and do my own research. All the rest cared more about standardized test scores and filling quota's, but that's what our tax dollars Tell them to focus on, so I can't really blame the teachers...

@Naxster With saying "nuclear bad", they mean, that the highly radioactive waist, produced by using nuclear reactors is very much indeed bad. And they're not environmental terrorists, even if you might say so, they are just concerned about, how the world will look in more than 500 years. They are not focused on immediate gratification, but more for a clean source of energy, that won't harm the coming generations on this planet. And they don't want to watch the world burn, that is not a fact, they just want to see a healthy earth in 1000 years, that is not unhabitable.

I donโ€™t understand why we donโ€™t just say โ€œwe accept that thereโ€™s no way to deal with inconsistent power generation for now, so we will just use nuclear for the next 150 years, and build up the technology and unleash the replacements at that timeโ€. Picking a direction, sticking with it, and planning for its end will give everyone an objective to focus on, and allow for us to maximize the quality of the resource we choose. Ultimately we canโ€™t afford to just keep discussing it while CO2 generation grows out of control. Nuclear has to be an option until we are far, far further down the line towards being net-zero emissions (and even then, we still will need years of net-negative to undo the damage). We are so far from being at net-zero, itโ€™s ridiculous to take this option off the table. The increase in electric cars will actually increase carbon emissions from power generation, as cars will be recharged at night. We need (and will need) much more electric power generation capacity, and the only way to guarantee it *without increasing emissions* is nuclear.

@Genomsnittet Chernobyl was an obsolete design even during its time that was built without a outer containment vessel just to allow easier extraction of material for weapons production. Something which no new plant in the development page, or for that matter any plant built in the past 40-50 years, has as a flaw. As for Fukushima, what's not stated so much are the over hundred other nuclear plants along Japan's coastline that shut down completely safely during a tsunami that killed almost 20,000 people, amidst a 9.0 earthquake. I would call that a pretty good track record to be honest, considering all of the other carnage that happened in the midst of the Tohoku quake. Absolutely nuclear has its safety considerations to be made but right now fossil fuel is an existential threat to continued human existence on this planet and if we don't act immediately there might not BE a civilization in a hundred years to generate electricity for.

Great presentation (as always). I like the opinion piece - both sides thinking theirs is the only route when it's clearly not. Unfortunately western politicians have become so short sighted that such long term thinking is beyond their comprehension. I believe that is the biggest thing holding up advances which will curb climate change.

The company Thorcon claims to serial produce Thorium Molten salt reactors in shipyards, making them floatable as a boat, then shipping them to the country that ordered them, Sink them in low depth near coastlines. These are safe selfregulating reactors which do not need water pressure to keep it liquid and hot, the biggest problem with classical reactors, this means they do not need the big concrete containment facilities which makes them a lot cheaper,also when there is a runaway effect salt self regulates that by expanding and making fission harder to happen. and even then safety features are installed that could prevent a meltdown but this would never happen. Also did I mention they are THORIUM reactors? Safer, more abundant and therefore cheaper to find and use as fission material than Uranium.

Thorium reactors need to constantly remove and store protactinium from the salt or they quench the reaction. This means you need a way to constantly filter out intermediate byproducts until they decay into U233. Pumping in and out highly radioactive intermediates in a molten salt, storing it for months, then reusing the U233. You can't make this work without exposing workers to extreme levels of radiation required to fix leaks and perform regular maintenance.

Have no idea what to compare it to maybe a hydro plant ?? it would show facts with the fear component of a meltdown taken out.

In British Columbia, there is a ban on the use of nuclear energy for commercial power generation. It is somewhat understandable given that a lot of Canadaโ€™s nuclear power plants are around 40-50 years old, and restoring and refitting them would be incredibly expensive. In for instance, itโ€™s a mistake to ban commercial nuclear energy if we have the regulatory capability to keep it operationally safe, accountable to the public, and as minimally invasive to the environment as possible. In BC and Canada, we should pursue research, investment, and development of next generation nuclear reactors if they are more modular and cost effective. It seems like the most obvious choice

@EdricLysharae I agree with you and my mind was changed, i think we can pull of Nuclear energy. However i dont think the Communication problem is eliminated by that at all. We didn't know about Tuenchamun (probably spelt wrong) and yet we dug him up. We Humans just have a fascination for Treasure hunting, just think about Nazi gold, people that run around with metal detectors. I am convinced that it is guaranteed that for some reason, whether it be archeology or treasure hunting or in the process of construction, that these things will resurface. Also i seriously doubt your thesis of "Dumping radioactive water in the Sea is fine" and that you can "Swim in the pool". Yes i read about this, scientist say even tho the risks can be below allowed levels but radioactive material, no matter the intensity is still a risk. Again, if its supposedly safe, why are the cancer rates in those regions significantly higher? Nuclear Energy yes, but we should also store this radioactive Liquids with the other trash and not dump it into the ocean

@Daniel1010, again, don't tell them where it is, or give any indication of where it is to future generations. Thus, you eliminate the communication problem. The storage issue is, sadly, probably a thing of cost. Most radioactive material stays in a cooling pool for many years before they are stored in containers. This is for two reasons: Water is a great circulator of heat, and that the hydrogen in water does a very good job at decreasing the distance ionizing radiation can travel. It's also very hard to irradiate water (any particles that are suspended in the water may be another matter.) But honestly, you could swim in most cooling pools, and as long as you didn't get too close to the submerged radioactive material, you would just be enjoying the pleasant warm water. That is also why people dump radioactive waste into the ocean. I don't approve of that, but I see the logic if you're trying to cut corners in your disposal costs. The issues for nuclear waste disposal are cost and responsibility: not capability.

Nuclear energy has its downsides most of which are the concerns that nuclear waste being misshandled and improperly disposed of, but nowadays nuclear waste is carefully disposed of deep underground, in basically massive storage units, and then filled with concrete and buried, and the history of catastrophic nuclear reactor failures the most notable being Chrynoble, but as long as we foucs on the idea of making these nulear reactors safer and reduce waste product to an absolute minium then truly nuclear is the way to go, and as stated in the video this could be a great way to bring in better versions of renewable energy that casuses less damage to the enviroments that they are placed in both when being constructed such as the large amount of achers needed for both wind and solar farms, and when there are being disposed of such the fact that some windmills are made up of fiderglass and solar pannels being made up of several toxic and enviromentally damaging chemicals that are either disposed of in burn pit or buried under soil where the toxic chemical can spread. I in general believe that we as humans need to get rid of all if not most fossil fuels and only ever really of them for emergency purposes in the future, but starting now we need to put the past behind us and lok at the facts decide what is truly the next best step in order for everyine to achieve the goal of making this little blue rock a little bit healthier.

It took an earthquake and a tsunami to bring the power plant in Japan to break down. Nuclear energy is super safe, as long as you keep those things in mind

After watching Michael Shellenberger's Ted talk, I am 100% for nuclear since then. I am from Australia and we still burn tons of coal for electricity. Nuclear is a taboo word over here, not coal.

@THEPedroTHE THETHE As you don't know where I got that long of a lifespan for Nuklear Reaktor, I have no idea why you would use 25 years for solar panels. The average is way lower, closer to 5-15 years, at least now as a lot of cheap Chinese made solar panels are in use, wich also lose toxic chemicals into the ground when damaged, wich they will get if you involve hail. On the endangered species thing there is an interresting thought that occurred to me: Neither Elephants nor Rhino's where endangered, until someone thought " Ah well there are enough of them, killing one or two won't hurt. Or twenty." I think we should learn out of history and prevent even the possibility of these animals to get endangered. And yes, power storage is a big issue. Especially since we use up a lot of lithium in barely developed batteries wich die fast. A bit more testing and researching wouldn't hurt.

@Alex the Russian Nuclear power plants require maintenence every 2 years, and have higher capital costs. I don't now where did you find that nuclear power plants had a lifespan that long. The biggest problem is technical nowhow, the engineers and scientist that are required to operate complicated reactors. Solar panels have a lifespan of 25 years, and can be recycled. Wind turbines only require maintenence every 4 to 6 months, and last 20 years. And, there are places with a lot of unhabitable land, which isn't home to threatened species, that can house those energy types. Energy storage is the biggest issue with renewable energy, and until a method to store energy is devised, nuclear is the best option for most of the world. As a stopgap solution, or permanent solution for small countries, they are welcome. But as the definitive solution, not really.

My country (๐Ÿ‡ต๐Ÿ‡ญ) built a nuclear power plant once, but due to the events that happened in Chernobyl international opinion made it impossible for us to use it. It's a bit of waste leaving the power plant in legal limbo when it could have been used to create electricity.

The interesting thing is that all of the major nuclear disasters were caused by oversights by either the design team or the reactor team, and the subject of the accidents were old reactors. The new reactors are designed much better and they have advanced failsafe technology so the chance of a disaster goes from 1 every few decades, to 1 every few thousand years. Nuclear disaster and operational casualty numbers are also comparable to coal power plant worker casualties per KW, and once you factor in the deaths caused by coal pollution in the world, itโ€™s a no brainer. Nuclear, even with old tech reactors, is the safest form of solid baseload power. New tech reactors take that casualty number per KW and drive it down even further. Now that comparison between big disaster casualties and coal worker/pollution casualties is a bit of a bad one, but it still gives good perspective to how horrible coal is. What needs to happen to make nuclear truly safe from disasters is to increase funding to develop safer next generation reactors and there needs to be extreme regulation on operation protocol and reactor design. Nuclear waste is becoming less and less as well as reactors become more efficient, and there are some very safe storage strategies. The amount of nuclear waste is minuscule as well, as Iโ€™ve heard that the nuclear waste produced over the lifetime of nuclear power in the USA only takes up a single medium sized room. Deep underground storage with robotic access is a great method. Iโ€™ve heard of ideas where you put the waste deep into a certain geological area where the earths geological processes suck it down into the mantle. If rockets become more reliable, then sending payloads into space isnโ€™t even a bad idea either, as silly as it sounds. It wouldnโ€™t hit anything for billions of years, and itโ€™s 99.9999% likely that it would just be consumed by some star somewhere. Given the small amount of nuclear waste created it wouldnโ€™t be much of an issue, as long as the chance of rockets exploding decreases dramatically. Renewables like solar and wind are a great idea in lots of places, but it cannot be implemented nearly fast enough and depending on the power source it isnโ€™t a great option for reliable power. Itโ€™s also quite expensive and resource intensive. Obviously thatโ€™s far in the future, if at all, but the regular deep underground storage is totally fine today. There have been no accidents related to waste storage in recent time with modern knowledge, or maybe even ever. I hope fusion ends up working out because that would truly be the best option for power and it would solve the worlds power issues forever. But for the time being, until we crack the fusion code, we must use nuclear to avoid extinction from climate change. We are running out of time, and constantly discussing the improbable future of a world powered by solar and wind is wasting it. We need to take action with the best solution we have right now and that is nuclear power. In the future when solar and wind power becomes feasible, replace the reactors, but until then stop wasting time and stop killing the environment.

@knoahbody69 Old reactor and design. Premade old design from GE and it didnโ€™t fit the tsunami and earthquake hazard of Japan but it โ€œwould cost too muchโ€ to redesign with proper safety back then.

It annoys to me to think the only reason nuclear is getting removed in a lot of places is because of a scared and misinformed public which politicians then cater to for their own personal power.

@Shumnee Actually the worst case scenario in Chernobyl was the fact that we had no idea what the hell we were doing with radioactive materials. Fukushima actually did have the worse case scenario thought out. A tsunami. But corporate greed and lack of regulations got in the way to stop the redesign of the reactor before it was built. Basically there was a backup generator that was at the waterline. Engineers pointed this out saying โ€œhey this ainโ€™t a good ideaโ€ but since the reactor was already fully designed by GE, the company contracting GE didnโ€™t want to pay more money to have it redesigned and they built it anyway. Then a tsunami floods the backup generator and then bye bye Fukushima. Any modern reactor does have every single worse case scenario designed into it, unlike the old ones which were honestly pretty scary. Coupled with the safer and more reliable failsafes if something unplanned does happen, the chances of a new reactor failing are fundamentally impossible.

@matt frank you realize a day in Chernobyl does nothing to you unless youโ€™re literally not the reactor right? Thereโ€™s even tours you can go on to Chernobyl. The dangers of radiation mostly comes from long term exposure. Exception being extreme radiation dose due to an accident.

The problem with those 16% of our energy use coming from carbon-neutral sources is that in reality it's a lot less. Those have to be built, and maintained, and that itself uses a lot of energy. Also, other problems might bite us in the butt a lot sooner than the problem of energy and emissions: rare earth minerals necessary for our technology, and phosphorus necessary for our food production. Those will run out very soon, and unlike energy, no viable alternatives have been found yet.

Hi, I've seen a lot from this channel, and both the narration and the graphics are really top notch overall, but I have several complaints here. Narration suggests that Nuclear power could be used at least temporarily till we get to 100% renewable, and then switched off somehow. Sorry but no. Given the nature of renewable sources being much variable and not uniform, with a terrible capacity factor and given you need accumulators for too many sheer energy to be sustainable, the only solution is to keep nuclear for the baseload and renewable for the peak consumption. Only alternative to nuclear for baseload is, sadly, "natural" gas (which is indeed "natural" but not that green at all).
