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.

      Stupid science Science doesn't know Viruses convert sunlight into oil fields. Viruses appearing for the first time on Earth are extremely sophisticated, viruses know to absorb photons ( sunlight ) to get energy the virus to work, after millions of years the virus developin algae . Algae convert photons turned into an oil field. Sunlight - absorbing algae convert into positrons + and electrons -- Algae uses 928 positrons + that attract 917 electrons -- creating protons + Algae 918 positrons + that attract 918 electrons -- creating neutrons Algae use 6 protons + that attract 8 neutrons attracts 6 electrons -- create carbon ( c55 h72 o5 chlorophyll ) Algae use 1 proton + to attract 1 electron -- generating hidro ( c55 h72 o5 chlorophyll ) Algae reproduce fast like bacteria When dead algae are deposited into sediments, sediments decompose after millions of years in to oil fields

    I love your videos. But could you make a video about how renewables are everything but sustainable? Dams disturb natural flow of water. Wind and solar have many not recyclable parts, And the materials needed for it requires A lot of new mines to be opened in Africa and South America, destroying the habitat we need to protect. 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.

    people who blindly recommend renewable sources of energy 100% without thinking about the repercussions or the challenges that come with it are the same people who are wannabe vegans, mostly tik tokers and 14-year-old white girls thinking they want fame

  • orcun

    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.

    I would love to know is there a way to keep them safe so things like before are not gonna happen again? Like, put the nuclear and its waste in a remote place, far away from people, so we can minimize the damage

  • 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.

  • Superduperchris

    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.

      There are barley any nuclear dangers with new nuclear power plants. They use nuclear pebbles instead of rods which if everything goes completely wrong the power plant will release barely any radiation. Which the chance of that happening is so so SO low.

    Solar and wind have no negative effects ? Oh please, Solar farm use Solar panels which reflect sun's energy back, every flying creatures who passes by will die of burning. And wind fields do the same, too. The turbo fans kill thousands of flying creature years by years. There're pros and cons of each type of energy, but if we want to step further, we have to use Nulear Energy. My country tried to build a Nuclear power plant once, but the locals were just too afraid of the consequence of nuclear waste so our government had to stop. As a citizen, i still hope our country can build one in the near future.
