Please be aware what planning means in the EU. It might happen or might not.

After killing both nuclear and russian gas I wonder how they'll do.

French politicians are already calling for people to reduce their home temperature by 2 degrees C to not be impacted by the Russian gas being cut off, and France uses way less Russian gas than Germany. With German electricity already being twice as expensive as France I'm worried for my 2022 electricity bill

Are they going to get the energy from unicorns?

Also half of EU gas comes from Russia, and 40% of residential heating energy is gas. So even before cuts Russian gas totaled 20% of residential heating energy, big slice but less than what is often made out in headlines and many of these consumers have air heat pump installed as well.
