    Hi, I work in waste handling, and I would like to tell you about dangerous materials and what we do with them.

    There are whole hosts of chemicals that are extremely dangerous, but let’s stick with just cyanide, which comes from coal coking, steel making, gold mining and a dozen chemical synthesis processes.

    Just like nuclear waste, there is no solution for this. We can’t make it go away, and unlike nuclear waste, it doesn’t get less dangerous with time. So, why isn’t anyone constantly bringing up cyanide waste when talking about gold or steel or Radiopharmaceuticals? Well, that’s because we already have a solution, just not “forever”.

    Cyanide waste, and massive amounts of other hazardous materials, are simply stored in monitored facilities. Imagine a landfill wrapped in plastic and drainage, or a building or cellar with similar measures and someone just watches it. Forever. You can even do stuff like build a golfcourse on it, or malls, or whatever.

    There are tens of thousands of these facilities worldwide, and nobody gives a solitary fuck about them. It’s a system that works fine, but the second someone suggests we do the same with nuclear waste, which is actually less dangerous than a great many types of chemical waste, people freak out about it not lasting forever.

    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.

                  No, there is pumped storage. Honestly, despite the plethora of start-ups claiming to have a solution (sodium batteries, molten-salt, etc) The only really proven way to store electricity for later is pumped storage, but that relies on geography (hills) which not everyone has. Batteries are great for phones, and cars but they simply don’t scale to countries.

            it has got cheaper, but it has to get cheap enough that you can buy enough batteries with the difference. I’m not sure it has become that cheap. Maybe these sodium battery things will get developed.

          You probably also didnt heard about Thorium based molten salt reactors, they are much safer than conventional nuclear, also cheaper, and you can have a 50MW installation in space not much larger than a shipping container. A 50MW solar installation is close to 1km2 and thats without any storage included. It even can be modified to run on spent fuel of conventional nuclear power plants.

        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.

      You can make Thorium reactors much smaller and cheaper, basically a 50MW unit is not much larger than a shipping container, while being much more safe than standard nuclear plants. The largest issue is over-regulation of the nuclear power in general.

      A 50MW of solar installation is HUGE, and thats 50MW at the sunniest part of the planet: https://newsaf.cgtn.com/news/2019-12-15/Kenya-launches-Chinese-built-50MW-solar-power-plant-MqC575l6Te/index.html, We are basically talking about close to a square kilometer installation…

      there is simply no way to call a 50MW solar plant cleaner than nuclear and its probably not even that much cheaper in the end. Compare that to a shipping container sized reactor… Only thing in the way, is the nuclear scare and government regulations.

        The cost is less from the design and more from the safety regulations. Best case scenario the state just starts making nuclear power plants, it’s just not a good idea to mix profit incentive with nuclear.

    If you’re interested in energy solutions and haven’t read the RethinkX report on the feasibility of a 100% solar, wind and battery solution, it’s definitely worth taking a look.

    Whilst I agree that we need to decarbonise asap with whatever we can, any new nuclear that begins planning today is likely to be a stranded asset by the time it finishes construction. That money could be better spent leaning into a renewable solution in my view.

      Exactly this. I am “in favor” of nuclear energy, but only in the sense that I’d like fossil power to be phased out first, then nuclear. Any money that could be spent on new nuclear power plants is better spent on solar and wind.

        I’d like Nuclear power not to be thrown out with the bathwater because it is practically essential for space travel/colonization in the long term. Solar panels can only get us so far, and batteries are a stop-gap. We need nuclear power because it is the only energy source that can meet our needs while being small enough to carry with us.

        All should praise the magic, hot rocks.

            We are no where near close to running out of nuclear material. And for its energy density, we are unlikely to run out anytime in the next 10000 years. It can also be found in asteroids or other rocky bodies, so unlike wood or fossil fuels, Earth isn’t the only place to get it.

    There are two main problems in my opinion, and they are both related to the “fuel”. First, uranium is rare and you often need to buy it from other countries. For instance, Russia. Not great. Second, it is not renewable energy. We can’t rely on nuclear fission in the long run. Then there’s also the issue of waste, which despite not being as critical as some argue, is still a problem to consider

      A big problem IMO is the generational responsibility of the waste as well. There needs to be decades of planning, monitoring and maintaince to ensure waste sites are safe and secure, this can be done but modern political climates can make it difficult.

      It’d be nice to prioritise it at least rather than tucking it away under the oil and gas rug. There is no real competition in energy output to a nuclear power plant. And despite its egregious up front cost, operating it is relatively low cost.

      In regards to fuel, uranium is used often but there is options such as thorium that have been used with some success. I do agree it is unfortunate to have to purchase from other countries but I think it beats buying natural gas from wherever it may be sold.

      The mining is also usually a really polluting affair for the region, much more than the what power generation might suggest. And overall, in many countries there is a lot of subsidies going on for hidden costs, especially relating to the waste and initial construction. So it is not as cheap as a first look might suggest.

      I’m not against it per se, it is better than fossil fuels, which simply is the more urgent matter, but it’s never been the wonder technology it has been touted as ever since it first appeared.

        One thing to remember about the mining issue is that coal mining is just as bad, and coal is often radioactive as well. More people have died from radiation poisoning due to coal power/mining than have died from radiation poisoning due to nuclear power, even when you include disasters like Three Mile Island and Chernobyl.

        Of course, we’ve also been mining and using coal a lot longer, but the radioactive coal dust and possibly radioactive particles in the smoke from coal plants is something that many people are unaware of.

        But, like you said, the big thing is to move away from fossil fuels entirely, and nuclear power has its own issues. It doesn’t so much matter what we go with so long as we do actually go with something, and renewables are getting better and better all the time.

      Yeeeeah, I wouldn’t worry about that. Sure we (Australia) are conservative with our fears of mining and exporting uranium, especially with the Cold War and reactor whoopsies around the world. But historically it doesn’t take much for us to go down on an ally.

      Just let us finish unloading all our coal off to the worst polluting nations first, then we’ll crack the top-shelf stuff.

      Except that you don’t need uranium for nuclear reactors. The reason it’s used traditionally because it’s also used for nuclear weapons. Thorium is a much better fuel that’s more abundant. China has already started operating these types of reactors. The other advantage of this design is that they use molten salt instead of water for cooling. Molten salt reactors don’t need to be built next to large bodies of water, and they are safer because salt becomes solid when it cools limiting the size of contamination in case of an accident.

        I don’t think it will. The large cost of a reactor will probably be shared, but fission plants don’t deal with plasma, magnets, hydrogen/helium storage, lasers, or capacitors. And we don’t even know the method by which a practical fusion plant will operate!

          I am talking in the sense that the same companies are participating in fusion research, and pretty sure the methods you mentioned are utilized somewhat in nuclear plants. Like handling and filtering radioactive materials.

            Radioactive waste maybe. Fusion plants are likely to create irradiated parts that degrade quickly, similar to fission plants. Fusion fuel on the other hand, is gaseous, and likes to escape. Hydrogen is explosive, while helium-3 is just expensive.

    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.

    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.

    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.

    I’m pro nuke energy but to pretend there are no downsides is what got us into the climate mess we are in in the first place.

    Cost, being a major drawback, space being another. And of course while they almost never fail, they do occasionally, and will again. And those failures are utterly catastrophic, and it’d hard to convince a community to welcome a nuclear plant, and if the community doesn’t want it then it can’t or shouldn’t be forced onto them.

    They also represent tactical strike sites in time of combat engagement. Big red X for a missile.

    There are also significant environmental concerns, as we really have no good way to dispose of nuclear waste in a safe or efficient manner at this time.

    It’s likely that nuclear based energy is the future, but you need to discuss the bad with the good here or we are just going to end up at square one again. There are long term ramifications.

      Worth noting that all modern failures have been GE models or ancient Westinghouse models. Modern nuclear reactors built by Westinghouse are virtually immune from meltdown, and Westinghouse is the lead player in new builds. Nuclear safety has come miles since the like of Fukushima, and especially 3 Mile Island. I’d feel perfectly safe living near a new Westinghouse nuclear plant.

        This is a shocker for many on social media but you can accept that something you want is not perfect but still want it, or see good in a bad person, but still not want them on the throne.

        Just because I can be realistic about it’s pros and cons instead of blindly parroting that I have been told to parrot doesn’t mean I can’t be pro nuclear.

        Other power sources have more problems. And I say just launch the waste into space and eventually the reactors will just be out of the stratosphere and it won’t matter if it explodes.

        But you got to walk before you can run.

        I just dislike when people pretend there are no downside to nuke, EV, wind, etc, because if they make one little comment on a con suddenly they’re some anti enviro Trump sucker and get dogpiled

          There’s a difference in something being not perfect and being fundamentally flawed. My confusion is because you perfectly verbalized why I think it’s flawed.

          I could understand being in favor of using nuclear temporarily until renewables are more reliable. I don’t agree but I understand the thought process. It’s a calculated risk, an acceptable gamble. But being aware of all the issues with nuclear and still be in favor of it long term, in my opinion, doesn’t make sense.

          Mind you, I’m not trying to attack you, I’m genuinely intrigued and curious.

            I dunno what that guy was thinking, but it seems obvious to me that nuclear fusion is the long term solution for energy generation.

            Nuclear fission not so much, but it’s definitely debatable which has more fundamental flaws between fission and wind/hydro/solar. All renewable energy sources ultimately depend on natural processes which are not reliable or permanent. And they also tend to disrupt the environment to some extent.

            Nuclear fission has no such limitations, but instead trades long term risk for short term stability. Basically renewable sources are and always will be somewhat unreliable, and Nuclear fission is the least bad reliable energy source to pair with the renewables. So in the medium term, fission makes a lot more sense than fossil fuels, and in the long term we should be looking to fusion.

          And I say just launch the waste into space

          This immediately discards like, everything you’ve said up until now, though. It matters if it explodes on the way up challenger style and irradiates half of the continent with a massive dirty bomb of nuclear waste. It’s way more cost effective, efficient, and safer to just put it somewhere behind a big concrete block and then pay some guy to watch it 24/7, and make sure the big concrete block doesn’t crack open or suffer from water infiltration or whatever.

              I mean to be fair you do make it pretty easy to discredit your entire argument, when you’re just gonna say that anyone calling you out on this very obviously stupid idea is a bot. Like that’s the same thing again.

              Maybe I’m a victim of Poe’s law, but I’ve seen “launch nuclear waste into space” get way more repute than it deserves as an idea from people who have no clue about the actual issues with, even just normal aspects to do with energy generation. It’s a shorthand signal that lets me know that someone’s had all their thinking on it done for them by shitty pop science and shitty science journalism. It’s like if someone believes in antivax, or something. I’m probably not going to really think they’re a credible source, after that. This is also bad if the shit they’re saying is itself lacking in external sources which I can rely on outside of them.

              I’m also flexing my brain right now because none of the shit you said at all really backs up the idea the nuclear energy is the future. Like, if you think it’s inevitable that more plants collapse and it’s inevitable that nuclear power plants get destroyed by missiles in times of war (also a great idea, on par with disposing of it in space, let me irradiate the exact area I’m trying to capture for miles and miles around), then you wouldn’t want nuclear power. If you believe in that and then you also believe in the overblown problem of nuclear waste, then there’s not really a point, there’s no point at which the benefits outweigh the drawbacks.

              The reason people aren’t going to accept nuclear if they believe it has cons is because like half of those cons are, albeit overblown, catastrophic for life on the planet, and the other half are failures to conceptualize based on economic boogeymen, just the same as with solar power. Political will problems, rather than problems with physical reality or core technologies. But still, problems that conflict with the existence of the idea itself.

              You’re not going to convince people to go in on nuclear power, your stated idea, if you only point out it’s flaws, and then also post ridiculous shit.

        If you start building a new nuclear plant today, it’ll start generating power around the year 2045, by which time renewables with storage will have gotten even cheaper.

        Bet you the public will be on the hook to pay for that white elephant because utility companies privatize profits and socialize losses.

        Cost is a proxy for productivity and resources. So while it is stupid to say that the energy transition is too expensive, shouldn’t we rather invest our productivity and resources into a faster and cheaper solution? Drawing focus away from renewables is dangerous as others have mentioned, because it is too late to reach our goals with nuclear.

          No I don’t think so. Nuclear is super effective and consistent, especially for large setups.

          Using renewables while we get our nuclear up makes complete sense. And subsidising nuclear with renewables after that also makes sense.

          But the technology to rely entirely on renewables isn’t really there either.

                  All the charts on page 15. The ones where they extrapolate exponential improvement for a decade while only citing themselves. Their prediction is 15% annually for storage cost improvements in Li-ion batteries which they call ‘conservative’

                  Our analysis conservatively assumes that battery energy storage capacity costs will continue to decline over the course of the 2020s at an average annual rate of 15% (Figure 3).

                  Let us check if their souce updated. $139 for 2023? That isn’t a 15% decrease since 2019’s $156, let alone year over year since then, which would be under $90. In spite of last year’s drop that is still more than the 2021 price of $132. I don’t know what ‘on track’ means to you but it must be something different than it means to me.

    literally the least efficient in terms of cost and time.

    battery backed renewables are a fraction of the price and are being deployed right now.

    edit: the tech is cool as hell. go nuts on research reactors. nuclear medicine has saved my sisters life twice… but i’m sorry, its just not a sane solution to the climate crisis.

    Given that solar and wind are cheaper, get built to schedule and far less likely to have cost overruns, this meme is bullshit.

    Sure, nukes are great. But we need clean energy right the fuck now. Spending money on new nukes is inefficient when it could be spent on solar and wind.

        Correct, but don’t forget that renewables is an umbrella term.

        If you use solar, wind, hydropower, geothermal and bioenenergy, you’re diversified and it’s all renewable. Add in storage and there’s not much of an issue anymore.

            Are you really bringing up resource limitation when your point is energy sources that depend on finite fuel?

            Besides, the current form of renewables is the best option we have right now, so we should put all efforts into that. Once we find something better, absolutely go for that.

              Uranium is actually quite common on earth, hence it not being included in the rare Earth’s minerals. Go get a shovel full of dirt. Anywhere on earth that shovel of dirt on average will contain something like a micro or nanogram of uranium. Shit’s everywhere.

            People just feel like there has to be a catch with renewable energy and latch onto the idea of rare earth metals. Besides cobalt having some use in some kinds of lithium batteries right now, theres not really rare earth stuff going into renewables. Solar panels are silicon and aluminum, wind turbines are simple machines connected to a magnet spinning inside coils of copper, lithium batteries are already being made with iron as the other component.

        We already have 30% nukes. Right now we need more solar and wind. I’m not saying shut down nukes. They are good. They are just a waste of money and time to build new when we have cheaper and easier to produce alternatives.

        This, this should be common sense, and I don’t understand why it’s not.

        Okay, so, say I need some energy that’s pretty dense in terms of the space that it takes up, say I need a large amount of constant energy draw, and say that I need a form of energy that’s going to be pretty stable and not prone to variation in weather events. I.e. I seek to power a city. This isn’t even really a far-fetched hypothetical, this is a pretty common situation. What energy source seems like the best for that? Basically, we’re looking at hydropower, which generally has long term environmental problems itself, and is contextually dependant, or nuclear.

        Solar also makes sense, wind energy also makes sense, for certain use cases. Say I have a very spread out population or I have a place where space is really not at a premium, as is the case with much of america, and america’s startling lack of population density, that might be the case. But then, I kind of worry that said lack of population density in general is kind of it’s own ongoing environmental crisis, and makes things much, much harder than they’d otherwise need to be.

        I think the best metaphor for nuclear that I have is the shinkansen. I dunno what solar would be, in this metaphor, maybe bicycles or something. So, the shinkansen, when it was constructed, costed almost double it’s expected cost and took longer then anyone thought it would and everybody fucking hated it, on paper. In practice, everybody loves that shit now, it goes super fast, and even though it should be incredibly dangerous because the trains are super light and have super powerful motors and no crash safety to speak of, they’re pretty well-protected because the safety standards are well in place. It’s something that’s gone from being a kind of, theoretical idiot solution, to being something that actually worked out very well in practice.

        If you were to propose a high speed rail corridor in the US, you would probably get the same problems brought up, as you might if you were to plan a nuclear site. Oh, NIMBYs are never gonna let you, it’s too expensive, we lack the generational knowledge to build it, and we can patch everything up with this smaller solution in e-bikes and micromobility anyways. Then people don’t pay attention to that singular, big encompassing solution, and the micromobility gets privatized to shit and ends up as a bunch of shitty electric rental scooters dumped in rivers and a bunch of rideshare apps that destroy taxi business. These issues which we bring up strike me as purely being political issues, rather than real problems. So, we lack generational knowledge, why not import some chinese guys to build some reactors, since they can do it so fast? Or, if we’re not willing to deal with them, south korean?

        I’m not saying we can’t also do solar and renewables as well, sure, those also have political issues that we would need to deal with, and I am perfectly willing to deal with them as they come up and as it makes sense. If you actually want a sober analysis, though, we’re going to need to look at all the different use cases and then come up with whichever one actually makes sense, instead of making some blanket statement and then kind of, poo-pooing on everything else as though we can just come up with some kind of one size fits all solution, which is what I view as really being the thing which got us into this mess. Oooh, oil is so energy dense, oooh, plastic is so highly performing and so cheap and we don’t even have to set up any recycling or buyback schemes, oooh, let’s become the richest nation on the planet by controlling the purchasing of oil. We got lulled into a one size fits all solution that looked good at the time and was in hindsight was a large part in perhaps a civilization ending and ecologically costly mistake.

        Global leader in nuclear is also China. They are actually building the reactors that cannot meltdown, but you also can’t make weapons from them, and they can run on the nuclear waste we have already produced with the crappy cheap reactors we use. We designed the reactors that China is now building 60 fucking years ago, and just shelved the design.

          The funny this is that I was a nuke person for a long time, until the facts changed. Nukes were really great fifteen years ago. But solar and wind have surpassed them in terms of cost so my opinion changed. Good shit.

      Windmil blades need to be replaced far more often than anything even half that expensive at nuclear facilities and require huge costs in chemicals and transportation. Off shore blades need even more frequent replacement. The best gelcoats in the world arent going to stave off salty air and water spray for long, and as soon as water gets in one small spot, the entire composite begins to delaminate. You don’t pay as much down the line with nuclear and you dont have to worry about offsetting the carbon output of manufacturing new blades so frequently.

        No, you just pay out the nose up front.

        If I had money to invest in the energy sector, I don’t know why I should pick nuclear. It’s going to double its budget and take 10 years before I see a dime of return. Possibly none if it can’t secure funding for the budget overrun, as all my initial investment will be spent.

        A solar or wind farm will take 6-12 months and likely come in at or close to its budget. Why the hell would I choose nuclear?

            Then we just move the problem. Why should we do something that’s going to take longer and use more labor? Especially skilled labor.

            Money is an imperfect proxy for the underlying resources in many ways, but it about lines up in this case. To force the issue, there would have to be a compelling reason beyond straight money.

            That reason ain’t getting to 100% clean energy in a short time. There is another: building plants to use up existing waste rather than burying it.

                Nuclear is nothing bog standard. If it was, it wouldn’t take 10 years. Almost every plant is a boutique job that requires lots of specialists. The Westinghouse AP1000 reactor design was meant to get around this. It didn’t.

                The experts can stay where they are: maintaining existing nuclear power.

                Renewables don’t take much skilled labor at all. It’s putting solar panels on racks in a field, or hoisting wind blades up a tower (crane operation is a specialty, but not on the level of nuclear engineering).

      Are solar and wind really “clean” energy? Everyone in this thread seems to ignore the costs of these methods.

      Every modern wind turbine requires 60 gallons of highly synthetic oil to function, and it needs to be changed every 6 months. That’s a lot of fossil fuel use.

      Lithium mining for batteries is extremely destructive to the environment.

      Production of solar panels burns lots of fuel and produces many heavy metals. Just like with nuclear waste, improper disposal of these toxic elements can be devastating to the environment.

      Of course, solar and wind are a big improvement over coal and natural gas. I dont want the perfect to be the enemy of the good, I just want to be realistic about the downfalls of these methods.

      I believe, with our current technology, that nuclear is our cleanest and greenest option.

          If we “all agree” and do a moonshot construction plan we could have electricity in 8 years. This is a fantasy, tho.

          Best case scenario in the real world is operational in 12 years.

          In the capitalist hellscape here in the US, a reasonable expectation would be 18-20 years.

          20 years also happens to be the lifespan of our wind turbines. In 20 years, all of the currently running wind turbine blades will be in a landfill and new ones will need to be manufactured to replace them.

          No reasonable person is suggesting nuclear as a short-term option. It’s a long term investment.

      You know renewables aren’t even the same thing as nuclear right? renewables aren’t consistent and it’s currently not possible to store the renewables anywhere.

      We already have over-capacity of renewables.

      Spending money on more doesn’t help when there’s no where to put that energy.
