People disliking renewables always say this.
Then when asked what method to price in the Swedish nuclear fleet having ~50% of capacity offline multiple times last year and France famously having 50% of the capacity offline during the energy crisis I always get crickets for answers.
It’s apparently fine when nuclear plants doesn’t deliver, but not renewables.
The difference with renewables is that it’s even easier to manage. Their intermittency is entirely expected and the law of large numbers ensure we never have half the capacity offline due to technical issues at the same time.
