Meta: for those unfamiliar, 1.21 GW is a reference to the 1985 movie Back to the Future . Clip of the scene in question: * https://www.youtube.com/watch?v=BDuZqYeNiOA * https://en.wikipedia.org/wiki/Back_to_the_Future If you haven't seen it, the entire trilogy is worth checking out: very fun and quite family friendly.
If you are a regular HN reader who is (or was until this post) unfamiliar with Back to the Future, I'd love to know three more random facts about your life. In my world view, you are part of a fascinatingly small group of people.

Absolutely false. Current flow is metered using current transformers. full disclosure: I install high voltage switchgear for a living.
Seeing current flow through switches isn't the same as seeing specifically where your power is coming from. Like, if power from several different sources flows into a single substation before it goes to your home, you know exactly which source created the electricity you're using? And if I purchase power from a 100% renewable company, is it always only electricity from their generators, never ever mixed in with power…

Like The Princess Bride or Labyrinth, BTTF currently remains a phenomenom of the 80's and 90's -- familiar to most from that time and deeply treasured by some, but not refreshed and sustained the way the Star Wars, Star Trek, Marvel/DC, etc brands have been.

France has 12% of Europe's population, and its primary energy is 45% from fossil fuels and 40% from nuclear power. The effect on Europe as a whole is therefore pretty small.
You're not counting the energy outflows from France to neighboring countries. Also, France gets 70% of its energy from nuclear, not 40%.
No, it gets 70% of its electricity from nuclear.

if it wasn't for France having primarily used nuclear power decades ago, Europe as a whole would be in a much much worse state when it comes to CO2 emissions. That makes it abundantly clear that nuclear needs to be a part of the mix when it comes to non-emission generating energy production.
Not sure if that still holds true nowadays with renewable energy and storage having got cheaper and cheaper.
There is a significant mismatch between reality and the kind of headlines we see in tech-focused media. These hype future products as if they were already widely available, which creates a false idea of the actual situation in the real world.

New renewable installations are getting cheaper, but are still far from being numerous enough to overcome their terrible load factor and enable switching off some baseline production plants. And storage at a grid level is pretty much inexistant, except for a couple of pumped hydro plants. There is a significant mismatch between reality and the kind of headlines we see in tech-focused media. These hype future products…
At least some of that is surely because of renewable power, mostly wind.

The result speaks for themselves, Germany still hasn't reached France 90s levels of emissions.
Energiewende didnt start in 1973, it was first authorized in late 2010. France's nuclear program was also very, very expensive: https://www.i-sis.org.uk/The_True_Costs_of_French_Nuclear_Po...
Skimming your source, I would not trust it very much.

Britain has switched off its coal plants. At least some of that is surely because of renewable power, mostly wind.
