      My problem is not with nuclear per se. We are pretty good at designing reactors these days. In areas where using renewables is difficult so not good for wind, hydro, geothermal, solar nuclear might have a place. HOWEVER. There is a high amount of regulatory capture that enables cutting corners on safety. Most of the time this will probably be okay but on occasion it will almost literally blow up in our faces. Mistrust of humans to responsibly operate nuke plants.

    21. DaRedWunsGoFasta

      The real problem with nuclear isn't the tech, but the people pushing for it, and the way it's extracted. For one, nuclear fuels are mined and processed by giant corporate players, who would stand to benefit from a swap to nuclear. They can monopolize the fuel source and charge for it whatever they want, with little regard for any economic or moral principle beyond short term gain. You can easily see this in how Rio Tinto leaves the areas in which it mines ecologically devastated and rife with civil conflict. Nuclear fuels are extracted at the price of human lives. As for who ends up using these fuels? You're gonna love this one: Critters like the Koch Brother(s)! They've been shilling and lobbying for nuclear, which, again, can be monopolized, for decades, the same way they've been shilling and lobbying for fossil fuels. Does anyone in their right mind really thing that new nuclear reactors will be well-regulated when the self-same corporate parasites that gave us the climate crisis are in charge?! Which brings us to, storage, intermittency and grid stability. These are talking points routinely flung around by corporate lobbyists as to why renewables are very, very bad. Thing is, those selfsame points apply to fossil fuel and nuclear plants. Those have malfunctions. Or supply chain shortages. Or other countless problems that cause them to shut down. And just about every time it's renewable sources that pick up the slack when nuclear and fossil fuels kick the bucket. Remember Texas? Which is run on both nuclear and fossil fuel, with only a barely-double-digit energy contribution from renewables? Well, when the recent blizzard hit, Texas' renewables outperformed all other sources in terms of reliability and proportional output, exceeding the power grid operators' own projections.

    22. Qwerty Qwerty

      I liked the gaming aspect of this video. I wish there was such game for the youth, to gradually form their perception of renewables and nuclear. It is clear that the current generation which makes the decisions is lost already and that only the new generation can make the more impactful changes.

    33. Parker Crowell

      Renewables will NEVER be the future of electricity because the components in Wind turbines and Solar panels only last several years before they become TOXIC WAIST. The biggest solar power plant in the world will become a WASTELAND soon. Not to mention the destruction of countless environments caused by building wind/solar plants.

    34. A Dw

      "Stop climate change" is a fallacy in itself. Cap all volcanoes, destroy the grass eating quadruped animals, stop exhaling and sacrifice yourself to trees and plankton. Oh, and tell the sun to stop.

      1. Pikmin

        @A Dw So it was the second one huh

      2. A Dw

        @Pikmin the human part hasnt been quantified. AT ALL.

      3. Pikmin

        I have a feeling you don't understand what that phrase means. Anyways, most people when they refer to "stop climate" change they most certainly talking for the humans part of it. Or maybe you decided it would be nice to take it literally and possibly out off context to write this comment and appear smart.

    36. FutureLaugh

      after my parents almost froze to death in texas this year, i dont really want to hear a word about wind and solar power. I want nuclear, ample amounts of energy- like the modern world uses. Its green, its renewable- and if regulations make it too expensive than stfu and change it if you care about the earth or energy.

      1. FutureLaugh

        @Simon Dahl Thats what makes it novel, because like stupid senators and politicians, it is not consistent. Im not going to rely on inconsistencies to function, nuclear works and its asinine to stand in its way.

      2. Simon Dahl

        @FutureLaugh Yes. Doesn't change the fact that wind works, but not if you have stupid senators and politicians.

      3. FutureLaugh

        @Simon Dahl renewables are novel but dont supply with primary and necessary energy supply. if you want to install expensive solar panels on your home to be green, and be fucked on a cloudy day or at night be my guest- but we need real power. if any pseudo environmentalist really cared about the environment, we would be deregulating and bringing modern nuclear to the main stage. what good is an electric car if it gets power from fossil fuels

      4. Simon Dahl

        The reason those turbines and panels failed, was because of incompetent politicians who don't realize you need to winterize your electricity production. Wind turbines and panels work fine everywhere else. Hell turbines work on Antarctica, and solar panels work on satellites in freaking space.

    37. Devantejah

      3:42 Yeah, that sounds all well and good but since Ringhals 1 and 2 was shut down in December 2020 and 2019 respectively we had to import electricity generated by fossil fuel and fire up the auxiliary generators that run on diesel to you know, meet demand due to it being winter. So that power plant runs at most at half the capacity now.

      1. Simon Dahl

        Jag skyller på sossarna...

    38. Kraken:)

      To combat climate change, the worldmust rapidly reduce its dependency on fossil fuels to reduce greenhouse gas emissions. Nuclear energy is low-carbon and can be deployed on a large scale in the time frame required, supplying the world with clean and affordable electricity.

    39. Carl Ryan Jay Masocol

      If we can't really stop using Fossil Fuels then why not plant Trees? Greenify the Metropolitan Cities with trees that Absorb much Carbon Dioxide?

    40. Sig_Necro

      The only reason why wolrd is not fullfied of nuclear reactor is because people dont think in the future lives.. they just care about themselves in the present and until the end of their life

        There is this thing called coolant systems..

    50. DeathlikeSilence

      Fossil fuels are like drugs. We rely too much on that shit, and need to kick the habit before we harm ourselves even more than we already have.

    51. damonstr

      It's vital to invest in nuclear power. It works and it is extremely safe with modern reactors. Remember, RBMK was cheap, big and old; and it had almost nothing in common with modern PWRs. I repeat, nuclear is SAFE.

    52. ellena jang

      Thank you for the video! I just think a fact check is required to see if building a nuclear plant in South Korea is actually quicker and competitively priced. As far as I know, the country is one of the countries which civil complaints are so harsh that it has been quite hard to build the nuclear plant these days.

    53. Ortavus

      Cant you just use magnets to create energy

      1. Ortavus

        @Lucky Izzac oh

      2. Lucky Izzac

        You need to spin the magnets in the turbine To do that we need energy

    54. albert mooney

      nuclear energy is the safest energy source, until it suddenly isnt.

    56. Cpt. Papandreu

      We need to choose an option. Humanity is currently like "yeah we need renewables lets do stuff, oh wait its not enough energy lets make fossil stuff, oh wait thats not good for our climate, lets test some nuclear, oh wait thats radioactive, lets to renewables...." Focus on something.

      what about nuclear fusion wouldn't that be one of the best ideas?

    65. Metao241

      Solar and wind are really bad for the environment in the sense that wind kills tons of bats and birds just by doing what they do. If you didnt know, bats are incredibly important for fruiting plants to pollinate (and other plants). Solar (depending where you get them but most use the cheap solar bc cheap) have very toxic chemicals that can seriously damage things like the water table and general soil health if they are damaged and leak those chemicals. I dont even need to explain why that is bad. Nuclear is becoming and has been the best and we should be using it. Its just better. But yeah its very hard to transition and it needs to be slow.

      Nuclear is the future, but certain companies both on renewable and non renewable side view it as a threat to their wallets. So they’ve made it impossible to go forward with nuclear

    73. white sky

      jesus christ, why dont we change to hydrogen and invest in it hardcore, maybe we need a video explaining it

    74. Muhammed Gundogan

      Yup electricity is like magic :D it is the type of energy that humanity has the most capability to manipulate it . Everything should be electrified but profit making is a great hindrance for it ; many petroleum or coal companies would not like to transition into nuclear or renewable energy due to profit margins. By current trend either the fossil fuels run out or global warming becomes too dangerous ; then humanity will shift towards it. We humans are really the most intelligent+foolish species on earth.

      Why can't we dump a large chunk of our unrecyclable waste into active volcanoes? Presently we are just shipping it out to poor countries and that waste gets burned there anyways.

      1. eZBoZz

        @Anon Surfer Ah okay, so Thermical recycling turns the heat produced by burning it into electricity, its not very effiecient way to produce energy, but its better than just burning it. There are even methods to fully recycle plastics so that they are reusable today, but they are too expensive so they dont get used

      2. Anon Surfer

        @eZBoZz Not talking about nuclear waste, but regular plastic waste. It's going to get into the atmosphere anyways when we burn it.

      3. eZBoZz

      The great tragedy of nuclear energy is that instead of showing the world how it can be saved, humanity instead used it to show how the world may die.

      Dude why did they not agree with Nicole tesla!?

    85. Da Real Wigga

      Only opinion I have is this. JUST DO IT! Renewable energy and nuclear energy cannot do the jobs alone. And while it's true nuclear energy is responsible for nightmares from the past, that's only because the nuclear energy was weaponized. If it was instead used to push fossil fuels out of the picture we'd already see a vast change in our climates. The truth is this, we best take action, and we best do it soon. Because climate change is not a good thing, and can lead to global extinction. Our governments and our society need to be persuaded that nuclear and renewable energy sources are the future, and it does not matter if they like it or not. Fossil fuels are doing nothing but harming the planet. And we risk the wrath of mother nature the longer we use it.

      * God's grace * Did you know that God loves you so much that he sent Jesus to save us? Jesus is the son of God! And he loves you very much! To have proof of this, we can say that he emptied himself of all his glory and stepped on the earth! Isn't that wonderful? And there's more! He assured us of salvation! He fulfilled the mission that God gave him! Which is to have a death on the cross for all people in the world! * How do I get to heaven? * It's very simple! -Accept Jesus as your Lord and only Savior! - Repent of your sins daily even those you don't know because you sinned out of ignorance! -Recognize that you do not deserve God's salvation but even with your faults He wanted to save you with his great love and grace!
