alt Hacker Newsboy am i tired of hearing that Dunkelflaute word as if its some kind of gotcha. Even ignoring the fact that you can continue to source power from other geographies during a localized phenomenon..... Just burn gas in peaker plants for the few days a year that this happens. That small amount of emissions wont matter for the next 50 years of decarbonization, after which we'll likely have plenty of other options.
The absolutism in all these arguments is so tiring, as if its not 100% perfect solution for 100% of every imaginable scenario than its no good. 95% reduction over a year would be astounding, we would have won the climate battle.
That's fine, but you need to include the cost of having barely-used gas peaker plants when calculating the cost of "renewables+storage". Laymen keep using arbitrary "marginal cost of solar with sun shining" to say "solar is cheaper than everything!". If it's true that capex of 80% gas peaker (and LNG storage and employees on standby and so on) + solar + wind + batteries is cheaper, then people should make that argument and provide the data.
