> We already have wires that cross continents to smooth out supply variations. It's exceedingly rare you get no sun and no wind over entire continents for an extended period.

I can be wrong but you would probably lose tons of efficiency even within High Voltage DC lines if everyday late night we take energy from different countries. Also this is getting outside of topic of discussion for me because one of the reasons we want Nuclear or Green energy in general is also the environmental plus the sovereign plus the long term affordability plans.

Another point from your first comment but if we run peak production in nuclear say in a country A, then the country A can also give power to Country B at late night similar to what you are proposed for solars.

> Again, batteries.

Once again, within my first comment I raise issue of battery. You mention a comment and I respond and then we get to batteries again.

I have no problem with solar at all without batteries but batteries really flip the equation in terms of environmental concerns.

My question is plain and simple, Why not Nuclear? I understand, I am not against Solar. Although environmentally, I feel like battery is a valid concern.

I am just saying that long term, Nuclear seems to be the better/best option. Why not Nuclear? That is a question which it seems that you may not have answered and that's a discussion worth having as well In my opinion too.

We can agree on this, correct?

HVDC is more efficient than you think, 3.5% losses per 1000km. Which means intracontinental is obviously good, and intercontinental will work in some situations.

Nuclear power is expensive, enough that “what about night” is solve by building extra solar and batteries. Also, renewables wreck the economics of base load power that needs to run all the time to pay back loan, but can’t compete with solar during the day.

Yes. Because they're the answer here.

Good luck with nuclear sovereignty, if that's your concern. How many uranium mines are in the UK?

> Why not Nuclear?

/me gestures at the last 50 years of historical evidence

"Why not try nuclear" is like "why not try communism?" for physics nerds. We have tried it.

I can't speak about UK but considering how cheap Uranium is, can UK not do cost analysis. Uranium is abundant material compared to Oil/Coal.

Maybe, but I think that, I can speak about the problem within US which I can better explain but US had nuclear fearmongering attempts and Senators passed laws which increased regulations on it to the point that some regulations contradict past regulations.

Nuclear power plants being built on loan in such a flimsy regulatory market was what lead to the downfall essentially within US

Nuclear fearmongering and lobbying efforts from Oil Industry as they are one of the most strong opposers of nuclear energy[0]

Once again, how do I explain this but nuclear produces 3.2x less carbon emissions than Solar[1]

We are able to build hydropower plants, we are able to launch spaceships into moon and outer space. It's definitely possible to build nuclear if lobbying effort decreases.

I'd say that its our dependence on Oil and Coal which have been the problem. I have nothing against solar and that is something that I am saying from the start. At some point we should look towards transition towards nuclear as well. To give up on that would simply not be ideal.

Wait until you hear how cheap and abundant sunlight and wind are!

Economically useful uranium deposits are only proven in a handful of countries.

> We are able to build hydropower plants, we are able to launch spaceships into moon and outer space. It's definitely possible to build nuclear if lobbying effort decreases.

This is the "well we haven't tried real communism" argument again.

Alright, So I think that some/most of my talking points were very inspired from the michael moore's documentary on the topic and I re-watched it after reading your comments. (Although Michael doesn't talk about Nuclear in the shortcomings)

I was going to ask you 3-4 questions but then I searched them upon myself and I do think that the results are more (positive?) than I thought.

Solar could feed world's energy needs by 0.3% and I think that Excess Solar could be used for green Hydrogen etc. too when needed for burstable energy source and smart grids in general to fix the ramp-up/ramp-down problem

I think one of the only things that I was sort of worried about mainly was the fact that Batteries produce lots of Co2 emissions and harm to the planet when mined but it seems that they have lifespan of about 10 years and can be carbon negative 3-4 years.

I don't know, I go through waves of doubt over Solar. I might need to learn more about Solar because I feel like I can just agree to whatever side I hear the recent data's from. Lies, Damned Lies and Statistics it seems.

But I feel like although solar is right direction too, we probably need smarter grids and just improvements within grid infrastructure in general too. Another point about Solar could be that there can be a more personal adoption of it whereas I can't build my own nuclear power plant so I do agree with you.

I'd still say that there is a lot of greenwashing in the Climate Change community to treat wood-chips and trees as fuel source and all the problems that stem from that with timber industry.

So although there are short-comings in Solar given its intermittent nature. I do agree that unless Govt.s create nuclear, it could be a good bet for personal actions/ even Govt.s to diversify at the very least from Oil.

I still think that though there is something wrong where People are wrongfully worried about nuclear. India for example had 3% of its energy coming from Nuclear and I looked at wiki and we planned even more but anti nuclear protests started happening after Fukushima Disaster :(

I am still really interested about Thorium Reactors and the race towards building it though. They are mostly disaster-free and Indian in particular has quite a large reserve of Thorium (25% of the world supply). The govt. is working on making 100GW to raise thorium's ratio in energy to almost ~10% estimate from 3% till 2047 which would still be impressive given that total energy would skyrocket as well till then.

India has true chances of being Energy Independent long term if it focuses on nuclear and Solar both rather than focusing on Solar given any advancement in Thorium reactor will be huge for us. For reference Coal : Thorium power ratio for same mass is 1:3.5 Million and its even more efficient than Uranium.

Also Thorium cannot be used for Nuclear Bombs in the sense of a fission unless you drop it at someone complete point blank but at that point its worthless compared to missiles so we can genuinely share this technology all across the world.

Thorium Reactors long term feel the future to me. So maybe I am too bullish on Thorium.

Solar is nice but atleast personally, Investments in Thorium Reactors could make India Energy Independent given 25% of the supply. We also recently found a huge jackpot in lithium and other minerals in Kashmir recently so I suppose long term India can be sovereign in manufacturing batteries for Solar production as well.

There is such a massive possibility in nuclear especially more so for India and general consensus also being within Scientific community that nuclear energy is cleanest forms of energy. The Combination means that, I'd want my govt. to take some risks in nuclear research/projects given how big the reward can be and that's also why I vocally support Nuclear. Much more than Solar. But I'd say that any govt. has their own risk profile and maybe Solar can be boring but works technology for Energy Independence so I just hope that Solar & Thorium both show some good numbers long term as well. So it isn't as if I am anti Solar as much as I am very pro nuclear energy long term.
