Also the sheer amount of land and wildlife destruction they require to build solar fields and windfarms…
Comment on Green party drops longstanding opposition to nuclear power
uthredii@programming.dev 3 weeks agonuclear is a massive waste of money now renewables and storage are so cheap.
And how cheap are renewables when the wind doesn’t blow and the sun doesn’t shine?
Renewables and batteries are awesome and we need more. But they aren’t suited to all weather in all countries at all times. The UK has periods where there is not enough wind or sun or battery storage to sustain demand. Nuclear is not my first choice but it is a practical choice that can be helpful.

I don’t see that as a problem, you don’t have to put solar on a nature reserve you can put it on a roof, carpark, canal. You can even put it on grazing land and it can increase biodiversity.
Besides the actual surface needed for solar is relatively small, you could power the UK with about as much surface area as is currently used by golf courses.

Ah, fair point then.

That’s why I included storage in my comment. Wind and solar are very predictable across a longer time frame.
Really? Can you provide a source for this?

The wikipedia article itself has many sources, I won’t pretend I have read them. Pretty sure I first heard of this in a modo energy video, but I couldn’t find it. Regardless it is a well researched phenomenon and is a real challenge we need to overcome.
Technically you could do it with enough battery storage but those batteries would be doing nothing most of the time when the weather is normal.

It’s right there in the article, “To ensure power during such periods flexible energy sources may be used, energy may be imported, and demand may be adjusted.”

What do you think a flexible energy source is?
It also says:
To be clear, I am in favor of importing electricity across borders but if most of Europe is affected by Dunkelflaute then I don’t think it would be sufficient. Lets hope for the best and plan for the worst.
