I remember so many nuclear stans on lemmy a bit ago refusing to acknowledge that renewables are getting so good and cheap that they are more important to solving climate change than nuclear. I wonder how they feel seeing investors pull out in favor of renewables?
Like crap? Renewables are good in places where they work. Nuclear works everywhere and is more reliable.
Investors pulling out of a nuclear project like this just looks like a, really dumb kneejerk reaction. "Oh! New shiny thing!"
This. Green energy works best when complimented with nuclear energy. Then, we can ween away from big oil.
It’s the opposite. Nuclear outputs as close to 24/7 as possible, you can’t ramp it up and down to accommodate variable output from renewables for practical and economic reasons.
The problem with solar is that the sun doesn't shine overnight. The good thing with that is that we use much less power overnight than we do during the day.
If you're relying a lot on solar, you need to build a big-ass battery that you charge during the day and use at night.
Alternatively, you build a nuclear or gas plant sized to overnight usage and run them 24/7. Then, you build way smaller batteries to handle dispatchability and smoothing demand over the course of a day. Nuclear is good for baseline power, and doesn't come with the environmental costs of a gas plant. It has a niche.
Big if true. Winds tend to be stronger at night though.
Or pumped hydro, compressed gas, molten salt, green hydrogen, etc.
Base load. See here: https://cleantechnica.com/2022/06/28/we-dont-need-base-load-power/
I mean you can vary it pretty significantly depending on the reactor type, but even if you couldn't you can still put the energy to work in alternative ways, such as pumping water up into reservoirs/damns to generate energy at other points, or using the excess energy to split water. There are many ways to use excess energy.
You can do the same with excess power from renewables though. My point was that you need something to fill in the gaps when renewable output is low, whether that be from batteries, pumped storage, peaker plants, etc.
Nuclear doesn’t fit in here, there are no nuclear peaker plants.
