It’s becoming increasingly common around weekends in France — which gets about two-thirds of its electricity from its atomic fleet
So they occasionally have to take a nuclear plant offline on a sunny and windy day, because we still don't have the storage for solar to be an effective baseline.
Well if that's actually the functioning case, they are investing their effort in the wrong place. They don't need energy production, they need storage.
As far as your comment amount solar, we do have solutions that exist. Energy companies just need to actually get off their asses and work them into the grids.
Who would "they" be in that case? The people who'd like cheap energy do indeed need storage. The nuclear lobbies on the other hand need to cripple their competition, so they only need their own, already present facilities and whatever means they can get to sabotage upcoming competition and secure their primary position.
Nuclear Power Industry: "We need to invest $10B in nuclear plants!"
Everyone else: "Why not just spend $1B on battery storage instead?"
Nuclear Power Industry: "Nah, that's not feasible."
isn't their next door neighbor Germany having an energy deficit crisis cuz they've been dependent on Russian gas for years? Maybe they could match up somehow
