Still straining to find some relevance in your assertions.
"when renewables only account for 20% of the mix."
30 to 40% according to the article.
Just a quick statistics lesson. Since coal/gas make up 70% of the mix they will of course cause the greater part of the decline. If they fall by 10% that means a 7% decline overall. Whereas so-called renewables, being only 30% of the total, will cause a 3% overall decline if they fall by 10%. So yes, coal/gas caused the greater part of the problem but then they are the greater part of the solution.
Prior to the system being gutted to accommodate so-called renewables, there was significant redundancy built in. No longer - there or here.
