tf wrote that title… nuclear is defacto renewable
No, it’s zero emission but not renewable.
Nuclear fission is actually by definition the least renewable energy source. Even coal and oil are renewable on long enough time scales. But there will never be more uranium than there is right now.
We actually don’t have that much of it if we consider the long term future, only a thousand years or so. So nuclear is intended to be a bridge to eventual full renewable power generation and storage, an essential component in the present day but it’s still a bridge.
Another thing to consider is that nuclear is the only power source that works in deep space away from the Sun. So if we’re serious about exploring the solar system or further, we’d be best not to burn up all of our fissionable material right away.

But if you go according the strict physical principle every energy source is non-renewable
The sun fuses a finire amount of hydrogen, earth has a finire amount of latent heat, the moon a finire amount of gravitational inertia etc.
And there’s a little paradox if you think about it, how can fusion be non-renewable but solar, that use radiation from the sun fusion, be renewable?
Fission and fusion are two different things.
No it’s not. That’s just delusional. All the ideas of a sustainable uranium fuel cycle are based on non-existent technology. Uranium is a finite resource and we have nowhere near enough of it to power the world, even if you ignore all the other problems.
there is enough U238 to last until we get there. except if you think fusion is more than 500 years away (yes, that number is out of my ass)
U238 is not fissile so that’s not very useful.
Honestly I don’t care if it’s solar, wind, geothermal, biofuel, or nuclear, as long as it displaces fossil fuels. And it’s feasible on a very near time scale.
If Sweden did an honest investigation and found that renewables would be more costly and take longer, let em get nuclear.
We need an “all of the above” approach. This fight between nuclear and renewables is just stirred up by fossil fuel interests. Either is good. Both is good.

Bullshit. Renewables are cheap as chips.
Think of a traditional power plant. There are 4 main cost catagories: Construction, Maintenance, Fuel, Demolition.
-
In a traditional plant, over the life of the plant Fuel will by far be the biggest cost.
-
For renewables, Construction, Maintenance and Demolition cost more (issues such as remote locations, weather, smaller generators means more generators which increases the mean time to failure) however they have ZERO fuel cost.
Renewable generation is profitable as fuck, moreso than nuclear. Your average wind farm pays itself off in less than 5 years.
This is a right wing government backing the interests of fossil fuels, by implementing policy that delays any meaningful reduction in fossil fuel use.
have you ever been in Sweden? it is a a rocky mountainous and mostly dark region. they only renewables that they can easily manage is geothermal and iirc they do not have the correct crust for it

Finally! Some countries are starting to make rational decisions!
