    Extremely.

    Even adding in construction and mining, it has the lowest carbon per KWh out of any option. Even Hydro comes out worse, due to the years of carbon and methane emissions from the decaying plant matter at the bottom of the newly formed lake.

    Wind and solar are down there, but the mining costs and the low output per unit tend to bump the numbers.

    Noted, that’s just the carbon released. There are other metrics, and nuclear tends to meet most all of them because it’s very heavily regulated.

      Humanity’s relationship with producing energy continually blows my mind, and it’s one of the main things that makes me think that maybe we do live in a simulation.

      We discovered fossil fuel energy, which was fine for a bit to kick off the industrial revolution, but obviously is super harmful in the long term. Then just as it was starting to become a problem, the universe went “okay, here’s this magic rock that just gives off energy, you can use that to generate massive amounts of power with no carbon.” And we just went “nah.”

      So then, the universe is like, “alright then, how about this: you can just get it from the sun, the air and water. Again no carbon and it’s infinite free energy forever, you’re welcome.” And again, we were like “no we want to just burn fossils.” Even now at the ecosystem is visibly collapsing around us we’re adopting it somewhat, but still dragging ass on it like crazy.

      It’s like whoever’s running the simulation keeps dropping the difficulty level to help us not die, and we just won’t accept it. I fully expect in the next century or so we’ll figure out cold fusion, build like two plants and humanity will just collectively go “BORING” and dig up more coal again.

        it isn’t “humanity” who stands in the way of moving on from fossil fuels, it’s a few hundred extremely wealthy assholes who own the fossil fuel industry

      That’s one hell of a claim. In fact such an outrageously bold one that you shouldn’t be able to post a comment like that without citing a reputable source.

      The Nuclear industry actually makes an effort to clean up after itself. Coal wouldn’t be such a big deal if they captured the carbon before it hit the atmosphere.

        Coal plants put out more radioactive material than even the bomb factories they call nuclear power plants. Newer plant designs are FAR more fail safe too, and some can actually ‘eat’ the waste from older plants.

        New nuclear is right up there with renewables, with the added bonus of being great for baseloads. The only problem is we needed to be building it 20 years ago, since it takes a long time to design, permit and build them properly. If we try to rely on them now, it will be too late.

            It’s relative harm. New nuclear is far cleaner than coal, and can slot into it’s place in the grid. We should have done this decades ago, but the plans languished till china found out about them. (Much to the designers joy)

            It’s also not an either/or situation. As china is demonstrating, there is a limit to how quickly you can roll out renewables. Doing other, pollution reduction in parallel makes sense.

            Taking nuclear off the table was the biggest win the oil barrons pulled off.

            On a plus side, we will finally find out if fusion is viable in the next 5-10 years. The first over-unity test reactors, designed for sustained operation are being built.

              Renewables are cheaper than building new reactors. Fusion is always viable in 10 years.

                Fusion has been 10 years away, with proper funding. It never got that funding. It struggled to maintain the break even funding to keep skilled people employed, and the lights on.

                The difference is that over unity has been achieved, in a normally sustainable manner. The funding is such that it’s 5-10 years at current funding. Most of that is building the actual test plants.

                I fully agree that renewables are currently the best cost option. The catch is that they are not viable everywhere. They are also inherently low density, so can get expensive in certain areas.

                Basically, we want a mix of options, to fit local requirements. Nuclear (and later fusion) should be part of the plan.

                In practice, I’m of the take what we can get. We need to crash CO2 output, and we need to do it yesterday. Anything speeding that up is a win, as far as I’m concerned.

                  Fusion has been 10 years away, with proper funding. It never got that funding.

                  Fusion got billions in funding and it led barely anywhere. Meanwhile renewables are the cheapest mass market options.
