    There are downsides to nuclear these days. Incredibly high cost with a massive delay before they’re functioning. Solar + wind + pumped hydro + district heating is where it’s at in 2024.

      This.

      Also, tie together more countries’ power grids to even out production and demand of renewables, and reduce the need for other backup sources.

      For a fraction of the cost of nuclear, increase the storage capacity as well. We’ve had days where the price per MWh was negative in many hours, because of excess production.

      The barriers to carbon free energy aren’t technical, they’re purely political.

        Yeah, back in 2010 and before nuclear was the way to go but with the incredible advancements in solar and wind it’s no longer the best option.

        Still shame on Germany for decommissioning nuclear reactors and deciding to build Nordstream 2 and burn coal as a replacement.

      Still not a reason to not build them, the entire point is for nuclear to handle the load when solar/wind can’t provide due to weather. Other renewables will still be producing the bulk of the power we need, but at night nuclear will be handling any demand spikes, each of them would greatly reduce the number of batteries required to satisfy the demand. They can stay until our solar output is so high we can just start electrolyzing water into hydrogen as energy storage.

        If you’re suggesting using Nuclear as a peaker plant or to turn it off and on whenever wind/solar is not up for it then I’m sorry to say that it’s not viable. Nuclear generators don’t handle well being turned off and on.

    Deep level irony that you used a Simpsons meme, which takes place in a city that suffers from a Nuclear Power Plant that doesn’t dispose of nuclear waste properly.

    Every form of energy generation is problematic in the hands of capital. Security measures can and are often considered unnecessary expense. And even assuming that they will respect all safety standards, we still have the problem of fuel: France, for example, was only able to supply its plants at a cheap cost because of colonialism in Africa. Therefore, nuclear energy potentially has the same geopolitical problems as oil, in addition to the particular ones: dual technology that can and is applied in the military, not necessarily but mainly atomic bombs.

    Also, I thought memes were supposed to be funny…

    Just because it’s safe doesn’t mean it’s the best we have right now.

    • It’s massively expensive to set up
    • It’s massively expensive to decommission at end of life
    • Almost half of the fuel you need to run them comes from a country dangerously close to Russia. (This one is slightly less of a thing now that Russia has bogged itself down in Ukraine)
    • It takes a long time to set up.
    • It has an image problem.

    A combination of solar, wind, wave, tidal, more traditional hydro and geothermal (most of the cost with this is digging the holes. We’ve got a lot of deep old mines that can be repurposed) can easily be built to over capacity and or alongside adequate storage is the best solution in the here and now.

      The problem with these arguments and the focus of debates is that they are based on nuclear energy from uranium, not thorium. Thorium is ubiquitous in nature, power centers are much easier to set up and can be small and the waste, while initially (a bit) more radioactive than uranium waste, loses it’s radiation level much faster

        The abundance of uranium and thorium is of the same magnitude. The thing is economics. Uranium is cheap, and as long it is, we use the sources we have. As the peice of uranium rises other sources get economical including sea water extraction which is effectively renewable.

          Uranium is a much scarcer source compared to thorium. Uranium can also be used to create nuclear weapons, that’s why other countries have difficulties using the tech because foreign powers are afraid of these consequences

    Nuclear lobby really tries to sell us to the fact, that it’s better to have control over power by a few big players. Must be terrifying to think about people creating their own power eventually.

    I hate to say it, but regardless of one’s stance, on his back should be “Public perception of Fukushima, Chernobyl, and 3-mile Island.”

    I say regardless of one’s stance, because even if the public’s perceptions are off…when we remember those incidents but not how much time was in between them or the relative infrequency of disasters, they can have outsized effects on public attitude.

      It’s not a great idea from the risk. If future governments let the windmills fall into disrepair, all that happens is windmills are useless. They can never accidently summon centuries of nuclear winter.

    It’s interesting watching the discussion in this thread evolving and polarizing. Yesterday the discussion started as ‘nuclear is one solution in a portfolio of solutions to combat climate change. vs. nuclear is always bad.’ and developed into ‘nuclear is good and you’re dumb. vs. nuclear is bad and you’re evil’.

    People are kind of missing the point of the meme. The point is that Nuclear is down there along with renewables in safety and efficiency. It’s lacking the egregious cover up in the original meme, even if it has legitimate concerns now. And due to society’s ever increasing demand for electricity, we will heavily benefit from having a more scalable solution that doesn’t require covering and potentially disrupting massive amounts of land before their operations can be scaled up to meet extraordinary demand. Wind turbines and solar panels don’t stop working when we can’t use their electricity either, so it’s not like we can build too many of them or we risk creating complications out of peak hours. Many electrical networks aren’t built to handle the loads. A nuclear reactor can be scaled down to use less fuel and put less strain on the electrical network when unneeded.

    It should also be said that money can’t always be spent equally everywhere. And depending on the labor required, there is also a limit to how manageable infrastructure is when it scales. The people that maintain and build solar panels, hydro, wind turbines, and nuclear, are not the same people. And if we acknowledge that climate change is an existential crisis, we must put our eggs in every basket we can, to diversify the energy transition. All four of the safest and most efficient solutions we have should be tapped into. But nuclear is often skipped because of outdated conceptions and fear. It does cost a lot and takes a while to build, but it fits certain shapes in the puzzle that none of the others do as well as it does.

      Some personal thoughts: My own country (The Netherlands) has despite a very vocal anti-nuclear movement in the 20th century completely flipped now to where the only parties not in favor of Nuclear are the Greens, who at times quote the fear as a reason not to do it. As someone who treats climate change as truly existential for our country that lies below projected sea levels, it makes them look unreasonable and not taking the issue seriously. We have limited land too, and a housing crisis on top of it. So land usage is a big pain point for renewables, and even if the land is unused, it is often so close to civilization that it does affect people’s feelings of their surroundings when living near them, which might cause renewables to not make it as far as it could unrestricted. A nuclear reactor takes up fractions of the space, and can be relatively hidden from people.

      All the other parties who heavily lean in to combating climate change at least acknowledge nuclear as an option that should (and are) being explored. And even the more climate skeptical parties see nuclear as something they could stand behind. Having broad support for certain actions is also important to actually getting things done. Our two new nuclear powered plants are expected to be running by 2035. Only ten years from now, ahead of our climate goals to be net-zero in 2040.

      No one talks about land usage for solar either. Which is a real shame, because with some relatively minor redesigns solar plants can be integrated into the ecosystem without causing massive damage, instead of what usually happens which is just clear-cutting a huge field and destroying any plant and animal life there.

        Nuclear plants also have to built adjacent to reliable water supply. I’ll bet the land is more expensive and a bigger environmental impact whereas the location for solar is more flexible

    I would rather see more investment on better renewable tech then relaying on biohazard.

    You would be surprised to know the amount of scientific research with actual solutions that aren’t applied cause goes against the fossil fuel companies and whatnot. Due to the fact that they have market monopoly.

      Modern nuclear energy produces significantly less waste and involves more fuel recycling than the historical predecessors. But these reactors are more expensive to build and run, which means smaller profit margins and longer profit tails.

      Solar and Wind are popular in large part because you can build them up and profit off them quickly in a high-priced electricity market (making Texas’s insanely expensive ERCOT system a popular location for new green development, paradoxically). But nuclear power provides a cheap and clean base load that we’re only able to get from coal and natural gas, atm. If you really want to get off fossil fuels entirely, nuclear is the next logical step.

        Economicaly might be viable, but there is so much unused experimental tech that has higher potential and scales better (higher scientific development as well).

      Nuclear is the best and most sustainable energy production long term. You get left with nuclear waste which we are still figuring out how to deal with, but contemporary reactors are getting safer and more efficient. Not to mention breeder reactors can use the byproducts of their energy production to further produce energy.

    Where the fuck we gonna put all the waste product? I’m not saying nuclear power is bad, far from it, but we have two problems here:

    • Its cost prohibitive to build new Third Generation reactors that are fault tolerant, and moreso to assure that all the Second Generation reactors are fully fault tolerant given how adjacent they are to flood plains and fault lines in the US
    • Where the fuck are we gonna put the waste at? Yucca Mountain is off the table for good, WIPP is nearing capacity for a pilot plant, and we have nothing like Onkalo planned out despite the funding being there many times over

    My issue with nuclear energy isn’t that it’s dangerous or that it’s inherently bad. The world needs a stable source of energy that compensates for wind and solar fluctuations anyways. For the current realistic alternatives that’s either going to be nuclear or coal/oil/natural gas. We have nothing else for this purpose, end of discussion.

    My problem is the assumption underlying this discussion about nuclear energy that it somehow will solve all of our problems or that it will somehow allow us to continue doing business as usual. That’s categorically not the case. The climate crisis has multiple fronts that need to be dealt with and the emissions is just one of them. Even if we somehow managed to find the funds and resources to replace all non renewable energy with nuclear, we would still have solved just 10% of the problem, and considering that this cheap new energy will allow us to increase our activities and interventions in the planet, the situation will only worsen.

    Nuclear energy is of course useful, but it’s not the answer. Never has technology been the answer for a social and political issue. We can’t “science and invent” our way out of this, it’s not about the tech, it’s about who decides how it will be used, who will profit from it, who and how much will be affected by it etc. If you want to advocate for a way to deal with the climate crisis you have to propose a complete social and political plan that will obviously include available technologies, so stop focusing on technologies and start focusing on society and who takes the decisions.

    One simple example would be the following: no matter how green your energy is, if the trend in the US is to have increasingly bigger cars and no public transport, then the energy demands will always increase and no matter how many nuclear plants you build, they will only serve as an additional source and not as a replacement. So no matter how many plants you build, the climate will only deteriorate.

    This is literally how the people in charge have decided it will work. Any new developing energy source that is invented serves only to increase the consumption, not to replace previous technologies. That’s the case with solar and wind as well. So all of this discussion you all make about nuclear Vs oil or whatever is literally irrelevant. The problem is social and political, not technological.
