    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.

        Please understand that negative prices are the market for electricity breaking down! That is not a good thing. It should mean that if you have solar panels on your roof you have to pay to participate in the national grid because you are dumping energy into the grid when it can’t use it, but special rules have been made for renewable plants. Literally, imagine a contract-to-supply for wind or solar…

          I understand very well the implications of the negative price, which is why I advocated NOT to spend trillions in nuclear, when issues of balancing demand and production can be solved for a fraction of what nuclear costs.

      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.

    In Spain we are starting to get negative prices every weekend for electricity thanks to renewables. France is not even close to those prices with their bet for nuclear.

    Don’t get me wrong, I love nuclear power. And I’m not a big fan ok what thousands of windmills made to our landscapes. But efficiency wise renewable is unbeatable nowadays.

      They don’t need to be exclusive. Power generation should be diverse. Otherwise prices will go through the roof on times without wind (happens in Germany). This can lead to higher energy prices in combination with high energy exports.

        Nuclear power does not solve the issue here. Nuclear reactors take hours or even days to ramp up or down. They are not quick enough to react to such occasions.

          True, it wouldn’t be enough, This is why Germany still has a lot of coal-fired power station and natural gas power stations, despite huge investments into renewables, and is also investing a lot into wood-fired power stations (imo a really terrible idea). The nuclear plants could still ease the situation by giving a stable basic load that has some planable variability (wind models are getting also better every year and aren’t that bad as it is). For now renewables cannot really provide a very stable basic load (at least not here, might be different for other areas).

          There are great concepts to improve all of this with stuff like pumped-storage hydroelectricity, but those cannot be build everywhere and take up a lot of space. It is going forward and I think nuclear power will come to an end eventually. For now, I think they still have their place (and imo Germany acted irrationally by shutting them all down).

          I mean, we’ve been lucky that France completly fucked their energy sector up (hints towards that nuclear plants probably also won’t be the ultimate solution), otherwise we’d have lost a loooot of money and would have had energy prices even worse.

      Negative energy prices are a bad thing! That means that someone is dumping energy into the grid (you should be paying the grid if you have solar panels!!) In the UK all renewable energy had to be called ‘experimental’ so that the pricing was fixed and the government picks up the tab - that’s not good. Check this map - right now the wind isn’t blowing and solar hasn’t got out of bed - so most of the countries using renewables are looking shit - later today solar will kick in, but tonight it will be bad again. That isn’t a solution.

    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…

    lol nuclear is really uneconommical, way too expensive and therefore really inefficient. You need 10-20 years to build a plant for energy 3 times more expensive than wind. For plants that still require mining. That produce waste we cannot store and still cannot reuse (except for one small test plant). For plants that no insurance company want to insure and energy companies dont like to build without huge government subsidies.

    I know lemmy and reddit have a hard on for nuclear energy because people who dont know anything about it think its cool. But this post is ridiculous even for lemmy standards.

    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

      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 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.

    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.

      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.

    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.

    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’.
