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’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.

Auf jeden Fall you do, otherwise you guys need to buy energy from France or importing natural gas from Russia via the almost finished Nord Stream 2, and also facing US sanction for dealing with the Russians or as a last resort, you guys will burn brown coal which increases carbon emission.

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.

We've been polluting earth with greenhouse gases only for like a century or so and the situation already got worse so much, we really need to move on from them really fast, because it will get only worse like really really fast, not in some future like century after, but during our life time in following decade or so And about Russia.. Yea, our country definitely can technically, but it won't practically simply because of corruption For real, 90% of the budget dedicated to build some new nuclear power plant will be wasted by higher up in the government "people" and it won't be finished even in a decade

Contrarians: “People are stupid! Why do they never try to fix it!? Why is it all getting worse? We need less emissions! We’re in a crisis! The world will never recover if we don’t find a way to slow it and stop it NOW!” Actual people who try and help: “I agree! We could slow it with nuclear energy fo-” Contrarians: “NO! Get rid of them! I want them gone! I heard somewhere on facebook that they’re bad!” Other people: “But...that’ll make it get even worse. You said we can’t afford that.” Contrarians: “People are stupid! Why do they never try to fix it!? Why am I the ONLY ONE trying to think of a solution!? I’m going to browse Tiktok whilst I’m thinking about how great I am for trying to make the world a better place. Any day now I’ll find a solution. Thank GOD I’m here.”

nuclear is even safer than renewable (hydroelectric power plant kill fishes, wind turbines kill birds and are made of glass fiber, wich in not renewable) the only nuclear problem is the radioactive waste, but we can covert it into new fuel for nuclea power plants). in conclusion: the biggest problem of the nuclear energy is the human fear and disinformation.

Fossil Fuel, Coal, and Gas : *kill millions and millions of people every year slowly but surely by Carbon emissions* Nuclear Power : *has 2-4 major incidents in history that was caused by lack of proper management and care while all of it combined doesn't have 1/2 of the kill count carbon emissions do in a year* Renewable : *fairly unreliable, takes more land, while less than fossil fuel and coal still somewhat kills environments*

Energy density is the smartest energy policy we have to date. Until battery capacity greatly increases, we should invest in nuclear to help us wean off of fossil fuels. Battery energy storage will eventually come with research, but for now, we should focus on whatever energy source provides the greatest amount of energy, and that's clearly nuclear
