I’m not saying “no gas”. I’ saying: no more PV or wind because we already stress our grid with too much electricity on some days and we have periods of days or week where we need to essentially generate 100% without any PV or wind.
You linked the same study for 5 times in this thread - you still misrepresent it's focus. The study concerns itself with the influence of social acceptance and how that reflects on the cost and efficiency of 'going green'.
I accept Fraunhofer’s technical modeling: they explicitly size ~500–750 GW of PV+wind by 2050 (≈6–9× average load) and still keep ~100–150 GW of flexible gas turbines plus sizable batteries for reliability (pp. 5–7). They target ≥95% cuts in energy-related CO₂ vs. 1990, but that still leaves a non-zero footprint—nowhere near France’s nuclear-heavy intensity (p. 11). Where I part ways is economics: today’s ~40 ct/kWh retail reality makes their rosy cost outlook look detached from how this overbuild-plus-backup approach plays out on the ground. I can appreciate Fraunhofer’s technical simulations—they’re excellent at that—but I’m street-smart enough to separate modeling optimism from economic reality, and that’s a distinction worth keeping in mind.
Maybe some street smart and “nuanced” thinking is something to consider? :-)
