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.

    Hands down, the future is not fossil fuels but nor is it renewables. It’s 100% nuclear. The future of mankind lies in the stars and you can’t get renewables beyond solar out there in our system, but to get the amount of energy you need from solar would require way too much to build and transport in or into space. Nuclear is the only answer beyond undiscovered technologies. We need to advance nuclear technology to the point where we get somewhat feasible reactors in space. Not only would you need less overall materials than let’s say a massive solar sail of some sort with an insane amount of batteries. The materials alone needed to power a ship or facility on a scale like that would be immensely smaller, last longer and produce far more energy using nuclear reactors than solar.

    I think renewable energy sources will have been exponentially high for the next decade and the objection to nuclear power necessarily will be wipe out , so countries such as Australia and Arabia which has a convenient place to set up solar energy must take some responsibilities to overcome this problem . We shouldn't forget this "we didn't take over the world from our ancestors , we just borrow it from our children. Today's world will be home for them as it does for us now".

      I mean, they’re depressing to me. I still watch em cuz they’re interesting. But most people would probably rather not have to be conscious of what a state we’re in, and a subset of those deny it entirely, and a subset of those think a god gave the planet to us and will magickally kiss it better if we do manage to fuck it up. Plus, our empathy for future generations is less than it probably should be because of the (temporal) distance between us and them, so a lot of us just simply don’t care as long as we live happy now.

    Nuclear energy is the only completely independent and reliable energy source. Regardless of climate change, there WILL be natural disasters and phenomena that can and will have a deleterious effect on the less reliable choices of wind, water and solar. A spaceship will have to use fission (and hopefully fusion) in order to operate in the future.

    Demand is increasing because increased quality of life requires greater energy. Then of course there is population growth. When I grew up in the 90’s, there was serious consideration to slowing population growth. Are we still working towards this goal, or ignoring it as a lost cause? Are we unwilling to consider a static population? Or does this violate some powerful instinct in too many people?

      Nobody’s born understanding their area. You don’t have to come out of the womb understanding nuclear engineering to eventually grow into a great nuclear engineer, same as you weren’t born knowing how to count but I’m sure you’re pretty good at it now. The only difference is that it takes more time and dedication to get into more specialized and technical fields. But if you’ve got the dedication and can put in the work of learning, you can do whatever you want. My tips would be first, don’t forget why you want to do it. If you’re really passionate about it, always remember that. Cuz when it gets hard, if you’re not certain of why you wanna succeed, you might give up. Second, start familiarizing yourself early, if you can. Maybe take some online classes about whatever the basics of nuclear engineering are, or even just watch a lot of educational HUfrom videos to keep that part of your brain engaged and thirsty for knowledge. If you want better information, you could try emailing a professor at a college and asking them what they think. I hope you don’t let some misguided thought that you aren’t “smart” mess you up. You’ve got just as much potential as everyone else, you just gotta allow yourself to believe it so that you can really work hard at using it. Good luck!

    Rather than having batteries, you could just use nuclear plants as a backup for whenever renewables are being inconsistent. Using Uranium as a battery is much more cost effective than using lithium.

    Ok I see a mistake here. Have you guys considered the energy consumption per population growth and area? Because small country with small amount of population and area have very less energy consumption so they need fewer and fewer nuclear plant and also can run without nuclear , using renewable energy. Also the climate to support wind, sun , tidal energy is different .AS PER THIS VIDEO I CAN SAY THAT ANTARCTICA IS THE MOST GREEN ( NOT CONSIDERE POPULATION, DEVELOPMENT, ENERGY CONSUMPTION, CLIMATE OR LAND):) oh and yes the other developed country was shown has done their part of pollution in early 20' to 90'. Now blaming still developing or non devloped country for climate change. There are so many problems here you haven't considered. This is not about which is better ENERGY!! This is about how much efficient it's to switch to them and most importantly the effect on climate of that

And the George Green magnet free energy motor. A city in Switzerland was powered with one. Or one of many thousands or millions of others. They've existed since 800 BC or earlier, especially from the 1400s on. They've been being patented in the USA since 1799, when a "permanent magnet mill" was patented! Of course some are fake so they have to test.

    I actually support nuclear but you fail to understand why people are against nuclear. Air pollution happens slowly so if a place becomes unviable for living people still have a chance to migrate . In case of nuclear you are already gone even before realising. Also the aftermath of nuclear accidents stay for hundreds and thousands of years. Air pollution is still way easier to counter by setting down multiple air purifiers.

    nuclear is better from what i understand. The batteries and storage that would be needed for the renewables would create alot of pollutants and would need to to be replaced just as much as anything else equipment wise. Also, do we have a good way for getting rid of or dealing with recycled batteries, all of the components? I'm on the side of more hydroelectric and nuclear.
