Sweden is going all in on nuclear power.The nation, led by centre-right coalition government and Prime Minister Ulf Kristersson is scrapping a renewable target of 100% and is instead going to build 10 new nuclear reactors. The government is passing legislation that currently limits the number of nuc
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.
Its not even zero emission…
What are the emissions, aside from waste heat?
The production of the uranium fuel, the gigantic building itself, the transport (the fule gets shipped around the world), the storage after its depleted.
Its definitely better than any Combustion fuels, but not at all better than actual renewables.
When considering these externalities for nuclear, you have to do the same for renewables as well. i.e. scrap turbine blades, concrete in dams, weathered PV panels, land use taken up by panels and turbines.
Remember that the materials used in most renewable generation are also shipped around the world and many have very dirty refining processes.
I’m a firm renewable energy supporter but you have to be fair to both processes.
You neglect the problem that the stuff from a nuclear reactor is literally unusable forever and becomes Special waste while the remains of renewables are recyclable, yes even turbine blades, there is just not enough market for it to attract a business so far, that will change of course with time, also the stuff is not toxic or radioactive…
Depends, newer version of the stuff don’t need rare earths, or much less, meaning the dirtiest of it falls out of the equation.
I am fair, nuclear is just not future proof for large scale usage. It also takes to long to be “effective” 10 years to build one powerplant, and is waaaay to expensive. you could build more actually renewables for less money in the same time and the electricity from it is basically free as there are almost no operational costs.
Renewables need all of that too plus they generate SHITLOADS of waste.
