@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis Sadly it is much easier to build an extra 10GW of peak gas plant than it is to build an extra 10GW of nuclear plant. The tradeoff is of course that the gas plant is inefficient and therefore extremely expensive per unit generated (but not used very often). Not to mention destroying the planet.
But that is how we largely managed it in the past.
In the future, and even the present, fortunately we have better options.
