That’s one hell of a claim. In fact such an outrageously bold one that you shouldn’t be able to post a comment like that without citing a reputable source.
Comment on New clean energy comes out. *look inside* It’s just boiling water again…
chaogomu@lemmy.world 2 weeks agoExtremely.
Even adding in construction and mining, it has the lowest carbon per KWh out of any option. Even Hydro comes out worse, due to the years of carbon and methane emissions from the decaying plant matter at the bottom of the newly formed lake.
Wind and solar are down there, but the mining costs and the low output per unit tend to bump the numbers.
Noted, that’s just the carbon released. There are other metrics, and nuclear tends to meet most all of them because it’s very heavily regulated.

It’s not that bold or outrageous… It’s been common knowledge for over 40 years.
Basically since the dawn of nuclear power plants we knew it was the cleanest form of energy generation. That was literally its selling point.
The problem was the fear of radiation if shit went wrong.
oce@jlai.lu 2 weeks ago
The consequence of this legitimate fear is crazy security and the cost of it. To the point where the cost of nee nuclear now struggles to compete with renewables. The new generation plants EPR are catastrophic in terms of budget and schedule.
chaogomu@lemmy.world 2 weeks ago
The thing is, it’s not a legitimate fear.
Radiation needs respect, but it’s not the magic death sauce that Movies and the Oil industry claim it is.
We swim in a sea if radiation every moment of every day.

Coal ash (from some mines) contains so much uranium that if emissions like this were detected near NPP all hell would break loose, but nobody cares. Energy content of that uranium can be higher than what was released during coal combustion
woelkchen@lemmy.world 2 weeks ago
“coal ash is worse” doesn’t make nuclear waste clean and non toxic. Both are dirty, just different kinds of dirt. Geothermal is an excellent “boil water” technology independent of weather and without toxic waste.
chaogomu@lemmy.world 2 weeks ago
Coal ash is dumped into a retaining pond by the ton.
Nuclear waster is highly controlled and produced by the pound and sealed into giant casks that can be struck by a full speed train without beaching.

I’m not defending coal, so stop trying that whataboutism BS with me.

there are still coal powerplants around and any replacement is better. geothermal doesn’t work everywhere

So what. That’s why power lines exist. Coal is BS, nuclear is BS. A healthy mix of renewables is possible right now.

Radioactivity isn’t clean.
cynar@lemmy.world 2 weeks ago
Coal plants put out more radioactive material than even the bomb factories they call nuclear power plants. Newer plant designs are FAR more fail safe too, and some can actually ‘eat’ the waste from older plants.
New nuclear is right up there with renewables, with the added bonus of being great for baseloads. The only problem is we needed to be building it 20 years ago, since it takes a long time to design, permit and build them properly. If we try to rely on them now, it will be too late.

That’s been rigged by design due to… interests… it doesn’t take that long to build one.
cynar@lemmy.world 2 weeks ago
Fully agreed, though it’s also something you really don’t want done on too much of an accelerated timeline. Rushing the construction, when the fail-safes rely on it, and it will be an absolute bitch to fix later, is a poor plan.
Unfortunately the red tape has become far too risk adverse. E.g. the reactors china is now building were designed in the UK. The UK government killed 5 attempts to get them built through red tape and time killing. Eventually a Chinese scientist found out about the plans. (With permission) he contacted the Chinese government. Sufficient to say, those plans formed the basis for the newer Chinese reactors they are building out now. They are also exporting the expertise, since most western countries have had their skilled engineers reach retirement, before passing on their skills and knowledge.
In practice, you are looking at 5-10 years minimum, from site selection to power on.
woelkchen@lemmy.world 2 weeks ago
Class A whataboutism. Both are dirty, neither is clean.
cynar@lemmy.world 2 weeks ago
It’s relative harm. New nuclear is far cleaner than coal, and can slot into it’s place in the grid. We should have done this decades ago, but the plans languished till china found out about them. (Much to the designers joy)
It’s also not an either/or situation. As china is demonstrating, there is a limit to how quickly you can roll out renewables. Doing other, pollution reduction in parallel makes sense.
Taking nuclear off the table was the biggest win the oil barrons pulled off.
On a plus side, we will finally find out if fusion is viable in the next 5-10 years. The first over-unity test reactors, designed for sustained operation are being built.

Humanity’s relationship with producing energy continually blows my mind, and it’s one of the main things that makes me think that maybe we do live in a simulation.
We discovered fossil fuel energy, which was fine for a bit to kick off the industrial revolution, but obviously is super harmful in the long term. Then just as it was starting to become a problem, the universe went “okay, here’s this magic rock that just gives off energy, you can use that to generate massive amounts of power with no carbon.” And we just went “nah.”
So then, the universe is like, “alright then, how about this: you can just get it from the sun, the air and water. Again no carbon and it’s infinite free energy forever, you’re welcome.” And again, we were like “no we want to just burn fossils.” Even now at the ecosystem is visibly collapsing around us we’re adopting it somewhat, but still dragging ass on it like crazy.
It’s like whoever’s running the simulation keeps dropping the difficulty level to help us not die, and we just won’t accept it. I fully expect in the next century or so we’ll figure out cold fusion, build like two plants and humanity will just collectively go “BORING” and dig up more coal again.

it isn’t “humanity” who stands in the way of moving on from fossil fuels, it’s a few hundred extremely wealthy assholes who own the fossil fuel industry

The Nuclear industry actually makes an effort to clean up after itself. Coal wouldn’t be such a big deal if they captured the carbon before it hit the atmosphere.
chaogomu@lemmy.world 2 weeks ago
It would take far more than just capturing carbon to make coal clean.

This page’s “Life cycle CO2 equivalent (including albedo effect)” page says Nuclear is just a hair worse than onshore wind in the median case, significantly worse than both on- and offshore wind in the worst case (worst for both types), and slightly better in the best case. In best case, hydro actually beats nuclear.
Also, TIL tidal power isn’t commercially in use. I swear we were learning about it in school 20 years ago, and were not even told then that it wasn’t viable.
Including the effects of albedo seems rather straightforward and worth doing. Of course it neglects some more complicated factors, like opportunity cost of staying on fossil fuels in the meantime for the 20+ years it takes to build nuclear. A convenient part of the reason that the biggest proponents of nuclear tend to be those politicians and special interests who also support fossil fuels.
chaogomu@lemmy.world 2 weeks ago
You don’t need giant 20 year plants.
Small Modular Reactors can be built and deployed much faster.
You don’t need to power an entire state with a single plant. You can scale it down to powering a single town. That’s the current push, mass production of SMRs.
