Do we need nuclear energy to stop climate change? More and more voices from science, environmental activists and the press have been saying so in recent years - but this comes as a shock to those who are fighting against nuclear energy and the problems that come with it. So who is right? Well - it is complicated.

    Unfortunately people here in Germany don’t educate themselves enough with nuclear energy, fossil fuels and renewable energy. Thus the green party took advantage of the disaster of Fukushima, led Germany go into a „nuclear energy, no thanks“ point of view and finally all the fossil energy sources are still running, while the low emssion nuclear power plants are being shut down. People do in fact need more education for this topic and I hope videos like this will find their way to more people

    I suggest that the nuclear power plant is the best way for this and next century, but we should control it and stop the reasons which blow up Chernobyl and Fukushima, i think we can gather all of the power plants from a land far from humans, like Antarctica or a hole country from south America, and then i think we can make a new robot technology or at least fewer workers to work and control the power plants and so that we get steam and next electricity. In any case of explosion or meltdown, we get fewer picture of disaster than Chernobyl.

      @Ariean Troy How is spent fuel in drum polluting earth's soil? It doesn't need to last for 27,000 years, just long enough to build a new one or better one or find use for the spent fuel. Geothermal ain't the way to go, the limits of it are more than obvious.

    • Ariean Troy

      Problem with nuclear plant is that its waste need to be stored in an extremely safe storage and they would lasted for 27.000 years! We want to save the earth from climate change by polluting the earth's soil?? This is why i think geothermal is the way to go.

    What has poisoned the well for nuclear energy is that those who make the profit from selling 'cheap' nuclear electricity while their plants are operating are nowhere to be seen when it comes to cleaning up their toxic long term legacy- that cost is carried by the general taxpayer. Same for fossil fuels, to be fair. What is sorely missing in this contribution is that the large and increasing consumption of energy is not an immutable given. Kurzgesagt bemoans that technologies to reprocess nuclear waste are known, but not fully implemented - but fails to mention that loft insulation, double glazing, heat pumps and white LED lighting also are known, but not fully implemented. The 'opinion part' begins well before he says so.

And the technology for renewables is hitting a plato. Its not the magic solution everybody is pretending it to be. And we're gonna NEED nuclear way more than people like to admit, a specially thorium reactors.

    Modern Nuclear is renewable energy. A 300 life half decay is nothing, we could store that waste in a warehouse waiting for it to stop being radioactive compared to the amount of co2 fossils pump in the air. This is what China understand but the west won't compete because the masses were brainwashed to believe fossil fuels good, nuclear bad and a 10year development cycle means the politician who implements it does not reap the rewards as he will likely be out of office when it comes online.

    i think all countries will create their own solar farms. they will share power to eachother. this way energy generated from sunny side of the world will give power to dark side of the world. i also think solar power in arctic areas will be used for reducing heat and producing electricity nearby countries. the main problem is weak electrical grid between countries. for example africa and asia has lots of areas for solar farms but political reasons prevent countries to invest these places. germany had to build solar panels but they don't have much sun. but increasing demand on green energy will force oil producers like arab countries to sell desert area for solar farms.

  • Nivyan

    My personal reasoning for Nuclear over Fossil fuel is actually pretty simple: Nuclear power might be more dangerous, but fewer humans are required to keep it steady - and they're all trained professionals. In contrast, fossil fuels generally require manual labour and *a lot* of frameworks to keep it going. The less humans are involved, and the more controlled it can be - the less accidents happen. The only reason fossil fuel is still here, is "for the jobs". We need to stop being selfish and accept change before the world changes without us.

    On earth? Probably nuclear energy could help but maybe become less popular in the far future A idea I have is that when we get to places like Mars, we could maybe use it there? It could be a place where coal and other sources of energy can be contained and used. If CO2 makes the world hotter, why not try that on Mars? would make the freezing wasteland hotter? Nuclear waste could also be stored there, as well as power plants being used there. That way in case of accidents, deaths can be a bit more minimalized and away from cities and places where mass death can occur? This is just a idea. feel free to criticize or give other ideas to me

    I’m curious though, would it be possible to create a nuclear reactor that would work under zero gravity, and if that is a possibility, why don’t we just move them to space and figure out a way to convey the energy they produce over massive distances (make it like a space station so that maintenance can be performed) and have some kind of storage module that could contain a large amount of nuclear waste. Then, a way to unload said nuclear waste or launch it at the sun so that it would burn up? I know this has probably been talked about somewhere but still it’s an idea haha.
