Scientists in California make a significant step in what could one day be an important solution to the global climate crisis, driven primarily by burning fossil fuels.

Does Nuclear count as Green Energy? I feel like it should, since it doesn’t really pollute and lasts a lot.

    Nuclear is absolutely green! The reason that nuclear energy is popular is that it’s remarkably easy to convert an old coal power plant into a nuclear one, all you need to do is strip out the insides, maybe modify some stuff, but the overall structure can remain pretty much the same. Thorium reactors are also much greener than the existing Uranium/Plutonium ones, with Thorium being ~3x as plentiful in earth’s crust compared to uranium. Additionally, it doesn’t require much of the very expensive ventilation equipment for mines as it doesn’t produce radon gas when it decays. And the best part is that Thorium reactors are meltdown-proof. The thorium can’t fission on its own, it needs a helper material like Plutonium, meaning you can basically just flush the thorium away and it immediately stops the reaction.

      Pro Nuclear is pro fossil fule as well. Stfu nuclear Stan.

      Nobody talks about the type of reactor, all make waste, all depend on mining, all take at least 10 years to, none are economical. Fuck nuclear. Go Solar.

        If they take ten years to build, start now. Nuclear plants offset 400 million tons of CO2 a year in the US alone. All the waste produced since the 1950’s would fit just over 9 meters deep on a single football field. Yes there’s mining, it’s not great, guess what? Solar panels and wind turbines also require mining. The open pit sort, the sort with wastewater containing the ever-perfidious radioactive elements. All in all, for each ton of rare earth elements extracted, about 2,000 tons of toxic waste is produced, 1-1.4 tons of which are radioactive, usually thorium and uranium funnily enough. A point of interest on the waste, the tailing dam of the Bayan OBO mine in China, responsible for only half the world’s rare earth elements, is around 70 million m3, the nuclear waste I previously mentioned comes in at 49,000 m3, or 0.07% of the volume of a single mine.

        All this to say, let’s build solar panels, wind turbines and nuclear reactors, because we’re in the harm reduction phase, and nuclear reactors are a fantastic tool even if they have downsides, just like everything else.

        Hi! So the other person completely demolished you, which is fine and none of my business, but it’s never a good idea to insult the person you’re debating against if you’re trying to change their opinion.

        Maybe you need to calm down.

        Nuclear is not the same as fossil fuels but it is, per dollar spent and per megawatt made and by waste produced, the best solution we have right this instant. Nuclear reactors last 30+ years when built and nothing in current green energy technology has that kind of longevity as far as I know. Green energy has peaks and valleys over a given day and current electrical grids are not built for that kind of short-term storage. Nuclear solves that problem. Battery-powered devices like electric cars also depend on mining, you know. Don’t solar panels also have electrical circuits that require mined minerals?
