    The real bottleneck now is grids and storage.

    And turns out nuclear has a few competitive advantages over solar. They are both great and serve different purposes.

      Nuclear is simply incompatible with renewables, if the price tag is of any concern to you. Nuclear reactors take long and cost a lot to build, still aren’t cheap to operate if you include the infrastructure cost of getting, handling and storing the fuel, can’t respond to chaning demand quickly and are centralized.

      Nuclear power plants need subsidies over their whole life, mainly to handle the risk inherent with nuclear fuel and the finincial risk of having to handle spent fuel for centuries to come. Nuclear power plants need to run at full power, which costs money every time renewables are pushing the energy price into the negatives. Nuclear power plants need a centralized power grid.

      Renewables work in exactly the opposite way. They are cheap to build and maintain, they are variable and decentralized. So to use renewables effectively, you need to build a decentralized grid and ideall, on-premise energy storage.

      Renewable energy simply wins in terms of cost, risk-management and scalability. So the energy grid of the future will be purpose-built to accomodate renewable energy. Trying to force nuclear energy generation into that mix only makes sense, if you have a clear, non-monetary reason to do so, like enriching uranium for bombs. For strictly commercial use, nuclear power is dead.

      Nuclear’s big selling point is that the sun goes down. Batteries have apparently missed that memo: they keep getting cheaper, better, and more efficient. Storage won’t solve every grid problem overnight, but pretending today’s limitations are permanent is a strange way to plan tomorrow’s energy system.

        another big selling point of nuclear is it’s easy to drop in at old coal plants that already have grid connections ready to go.

        pretending today’s limitations are permanent is a strange way to plan tomorrow’s energy system.

        how long are you willing to wait for perfect energy storage?

        obviously battery tech will improve, but the point is we cannot afford to assume that problem will be solved 100%, meanwhile experiencing more and more irreversible damage to our environment. We need to put our eggs into all clean energy baskets to get off CO2 as soon as possible. Not whenever battery tech happens to be ready to handle everything.

          “it’s easy to drop at a place that has grid connections”

          Funny, because solar or literally any other plant will also benefit from having existing connections, and all of them are easier and cheaper to build than nuclear.

          Nuclear is dead but for niche applications.

          Nobody’s asking us to bet on miracle batteries: Wind and solar paired with storage are already cheaper than building new nuclear. Reusing a coal plant’s grid connection doesn’t magically make a reactor cheap or quick to build. If speed and CO2 matter, follow the numbers, not the nostalgia.

          No, in my world tomorrow’s grid uses whatever delivers reliable electricity at the lowest total cost: solar, wind, hydro, geothermal, storage, and yes, nuclear if it can compete. This isn’t a religion with approved energy sources. It’s an engineering problem with a price tag, and nobody gets bonus points for glowing in the dark.

            Exactly, this is an engineering problem. You’re talking it like it’s an accounting one. Reliability, emergency use, redundancy, generating potential and universal scalability are the most important factors. Cost is a completely separate issue governed by separate factors, many of which are 100% artificial.

              You’re stringing worlds together at this point.

              Cost is the single largest factor in the deployment of new power plants, and solar is just impossible to match right now.

              You could spend literally decades and billions building a nuclear plant, or start deploying solar right this minute and immediately reap the rewards of that investment.

              It’s a no-brainer.

                But it doesn’t need to be one or the other. The more diverse the grid the better. I’ll also say again, cost on both sides is mostly artificial anyway.

              “Glowing in the dark” refers to nuclear power sources. Hope this helps.
