With 100% renewables you would need almost 100% storage and potentially for multiple days, with a nuclear baseload you'd only need storage for the peaks, you could even use excess renewables to charge up the storage for these peaks.

What do you mean with 100% Storage? And why would you need it for multiple days if you have a grid that transports energy all around the continent and in future possible worldwide?

[-] WagnasT@iusearchlinux.fyi 1 points 1 year ago

I guess we can talk about transmission then, yes if you can get enough renewable energy across a continent then in theory you can transmit it to where it is needed, however you would need a LOT of transmission capability that is not currently available. The current interconnects can handle an impressive amount of load but you're not going to transmit enough power for all of sweeden from spain. There are some massive transmission projects underway that should help address this but they're still not going to be enough to cover a 100% outage for most places. So a cost analysis would have to be done to determine if massive transmission projects are better than building nuclear plants. Keep in mind, these same transmission lines can transmit nuclear power as well so they should be built regardless of what energy source you use.

can be build faster and cheaper than nuclear, doesn't need fuel and needs to be build anyway. We get the cheapest, strongest and least dangerous grid if we invest in more renewables, storage and better transmission. And that's something we can get done fast and start harvesting the profits in a few years.

I mostly agree except transmission is not cheap, and further I'm not convinced transmission across a continent is even possible even with crazy high voltage DC lines which currently don't exist. The current massive projects are going to take several years for just a few lines, it would take an insane ramp up in production to do the entire continent. While we're working on that nuclear can be built reasonably fast without political hurdles blocking every step of the way. That's not to downplay the need for recycling the waste which will need to be invented regardless because the waste already exists. I'm also not convinced renewables can ramp up production on a scale that would be able to replace in excess of 100% of the demand within a few years, but I guess I'll have to look that up. Your concerns about nuclear are valid, but rebewables won't magically solve all the problems of reliability and scale, we're going to need a baseload and nuclear has proven for decades that it can do the job.

[-] derGottesknecht@feddit.de 1 points 1 year ago

High voltage dc transmission lines already exist and are already in use .

This is build faster and with fewer risks than nuclear.

[-] Serpent@feddit.uk 1 points 1 year ago

Not sure about the 100% point but you will certainly need long term storage which is an unsolved problem. A point I wanted to make was that with enough renewables installed you have the baseload. You would also have an excess of production at peak times that would be useful to store long term.

My personnal view is that a sensible energy mix should have some nuclear but I don't think it is the key to solving our future energy requirements and should be minimal as it isn't good value.

[-] ricdeh@lemmy.world -1 points 1 year ago

Entirely unsubstantiated. Renewables require storage only for the peak demands, otherwise, they function as a baseload, provided that there is a sensitive balance of wind and solar power generation installations.

[-] schroedingershat@lemmy.world -3 points 1 year ago

If you want 99.9999% uptime with no backup then the nuclear fleet will need months or years of storage due to the prevalence of correlated unplamned outages.

Back in reality, a good enough renewable system with >95-99% uptime has less than 10% of the storage that will be found in the accompanying country's EV fleet. Even if you are too allergic to nuance to understand the real solution for the remainder, simply planning a renewable rollout and assuming existing fossil fuel peakers for down periods over 12 hours will take 20-100 years to release as much carbon as delaying one of the years waiting for late, over budget nuclear reactors.

And thus you have shown that your mind is made up and no amount of evidence will sway your decisions. Good day.

[-] schroedingershat@lemmy.world 0 points 1 year ago

I'm plenty open to evidence, it's just every time I look at some it shows a new lie that nukebros tell. Every single talking point isnutter bullshit to the pooint where if you look it up you find that nukes are significantly worse by whatever hair-splitting metric is being used ti try and distract from their main downsides.

There is a fully renewable solution for the 2-5 >100 hour events a year where battery storage is unsuitable, but it requires holding more than one thought in your head at a time (thermal storage, dispatchable load and w2e is one combo).

[-] WagnasT@iusearchlinux.fyi 2 points 1 year ago

That's not very open minded. I'm all for vetting your sources and skepticism, but going in with your mind made up is close minded.

Look my dude, you're clearly here to fight not discuss, and that's fine we absolutely need to fight against the establishment, activisim is important. Fighting against your allies is a pro gamer move though.

[-] schroedingershat@lemmy.world 0 points 1 year ago* (last edited 1 year ago)

That last bit is the rub though. I'm fighting to decarbonize and reduce exploitation kf resource rich countries and you're fighting to stop it.

The constant tirade of insane lies is tolerable. Pretending you're not on the side of fossil fuels is the incredibly insulting bit.

[-] Exatron@lemmy.world 1 points 1 year ago

No, the insulting bit is youd constant tirade of insane lies, buttercup.
