    Nuclear energy is not clean. Less CO2 intensive, maybe, but definitely not clean. It might be good in the short term but the long term looks grim regarding nuclear waste, among other issues.

      Nothing is “clean”. Wind/solar manufacturing are themselves polluting and would need massive amounts of battery storage to be moderately reliable that generates even more pollution. Geothermal is probably best but depends even more on location.

              You started with

              Nuclear energy is not clean. Less CO2 intensive

              If you meant to include oil in “less co2 intensive” just say so, then we can talk about it.

                What? No. I was merely putting in perspective that nuclear energy is not a magic thing that will solve everything.

                  It’s not magic, but it has advantages that are hard to beat in terms of resource usage. Renewables also have advantages, but you can’t handwave away their own problems and limitations anymore than you can do so for nuclear energy.

      Yah but we can manage Nuclear waste. We can’t manage runaway climate change. CO2 is the enemy.

      The US produces less than half the volume of an Olympic-sized swimming pool of nuclear waste per year in total, so it’s not exactly hard to manage. Wind and even solar take up a lot more space than nuclear for the same energy, even if we were to consider decades worth of nuclear waste storage. Nuclear power production has about 130x higher density than wind, and needs 34x less space than solar PV.

      And that’s considering that the US doesn’t even use their used nuclear fuel efficiently like, say, France. 96% of French nuclear fuel is recycled by them, while the US doesn’t really recycle their nuclear fuel. Thanks to free market capitalism fuel recycling never got commercialized in the US, so the over of century of usable fuel we have in recyclable nuclear fuel is just wasted. It’s cheaper to just buy new fuel rather than recycle, so of course companies don’t recycle. American problems I guess.

      If space were a big issue than nuclear would still win by a long shot even over the long-term. There’s very little of it produced, it doesn’t take up much space to properly and safely store for tens to hundreds of thousands of years, and the power production is extremely reliable so you don’t need miles upon miles of giant batteries to store excess power just in case.

        Storing and monitoring that waste for 100’000 years is too expensive, even if we manage to do it.

        Nuclear power is simply not cost-effective.

        I am very well aware of the state of nuclear waste in France, and it’s not 96% recycled. This is absolutely laughable.

          I should say up to 90-96%. It depends on the methods and the type of fuel you use. Currently widely used nuclear technology is more like 30-50% recyclable. That number is able to be increased by using more recyclable fuel technology, which is available.

          French nuclear waste in total is 0.0018 km³ (three olympic swimming pools) after 8 decades of using nuclear and primarily using nuclear for 4 decades, so I’m not so sure how you imply that the “state of nuclear waste” is bad. Even with the “inefficient” ways of using/recycling nuclear, there’s not a lot of waste produced in the first place.

          Only ~10% of French waste is actually long-lived too, meaning after a few decades to 3 centuries, 90% of it will no longer have abnormal radioactivity. Meaning the radioactiveness of the waste just goes away on its own after a moderately short period of time and it basically just turns into a big rock.

      It might be good in the short term

      Considering that modern reactors seem to require well over a decade to be built, not really “short term”, and certainly “too late” for any sort of climate related purpose of emission curbing.
