I think it behooves the US and any other country serious about both climate change and extra-planetary exploration and colonization to develop a robust terrestrial nuclear power program as well as encouraging a trained cadre of nuclear engineers who can manage nuclear power sources on other planets, satellites and space-craft.

Is the US serious about extra-planetary colonization?

if (US == "Musk") ? true : false

Articles like this miss the main point and instead focus on culture war material. There are plenty of sites that would happily accept more nuclear being built, but all other forms of energy have undercut the cost of nuclear. It's no longer cost competitive, and places like China that adopt a "let's try everything and see what works best" approach have heavily pulled back on nuclear. The issues aren't safety, waste, a…

This assumes that larger investment in nuclear won’t yield reduced costs, just as larger investments in solar did.

i just dont buy it. hypothetically, there is a nuclear power plant design that is perfectly safe in that it will never melt down. but there is no nuclear power plant that produces no waste. as long as you are producing waste, you are depending on bumbling bureaucrats to properly dispose of that waste and manage the waste often for extremely long periods of time. its just not an ideal situation. the government cant ev…

Isn’t there still a lot of implied waste from the solar panels themselves though, as well as the storage batteries i.e. once they’ve reached their end of life?

My understanding is that this cost and the manufacturing cost (rate earth metals etc.) are often overlooked when reasoning about the total footprint of both solar and electric vehicles..

A grid that relies on transmission to that degree will require unifying some disparate grids won't it? Also it seems horribly vulnerable to attacks digital or physical.

Disclaimer1: I'm "pro" nuclear (as a baseline to supplement hydro), and i think nuclear is the 3rd best option (behind hydro and reducing consumption) Disclaimer2: i have investissment in veolia

Panels do decline, a lot, and especially older panels, but also most newer industrial solar PV are using heavy metals that can burn land (I mean, go to indonesia and look at farmland or even forest near communities were ONG installed a lot of PV before the tsunami, you'll understand what i mean, you can literally see where those PV were buried).

Veolia Rousset plant was the first to recycle most of the materials (the shareholder paper said almost 95%, i believe them) and not simply landfill them. But this have increased cost, and right now, most PV panels end up in landfills, poisoning earth for decades (and now that we understand saturnism)

I'm not saying PV is not a solution, it is, especially locally, but it have to be handled well. But you can't have solar+wind make up more than 50% of your electrical network, its not possible. And even 50% add a lot of costs.

Batteries should be refurbish-able and definitely recyclable.

It seems like the largest feature of modern nuclear power is that it got a lot more expensive as we realized how much safety we truly needed to build into it. Whereas, without much prompting, solar got a LOT cheaper.

When nuclear develops that significantly, we will all pay attention. Until then, build cheaper sources.

Also consider when building nuclear, you are locking into technology from 10 years ago (when the plant is finally done), for the next 50 years (when the plant is finally decommissioned). Solar and other sources have much faster iteration cycles and much lower commitment.

If you're worried about attacks, you should be even more worried about nuclear.

Solar requires energy storage. It is not on demand. Wind and solar must be backed by an on demand source as we don't have sufficiently cost effective storage methods.

Options are then basically hydroelectric, natural gas, petroleum, coal, or nuclear. Nuclear is the cleanest if you can't put a dam somewhere.

The issue with radioactive waste is more of a political and emotional problem than a real one. The amount of waste is rather small and it's not like it will irradiate you from a kilometre away :-). It can be stored in safe containers and buried in stable geological sites or even stored temporarily for many years in storage houses and maybe later re-used in types of reactors that will be able to recycle the spent fuel rods. Whole US produces 2000 tones of radioactive waste a year. In fact, the U.S. nuclear industry has produced roughly 64,000 metric tons (one metric ton equals 1.1 U.S. tons) of radioactive used fuel rods in total or, in the words of NEI, enough "to cover a football field about seven yards deep." Which really isn't much compared to any other pollution.
