It is generally not the case in modern construction or outside cities (because you need "gaz de ville" otherwise it is a real pain, and that is infrastructure). This 2015 document indicates 39% natural gas in heating, and 35% electricity https://www.insee.fr/fr/statistiques/fichier/3280930/Enviro1.... I am currently living in an old city house with gas available for both heating and cooking.

In big cities like Paris I believe it is discouraged even when available due to the risks and housing density.

Awesome! Thanks for digging that document, it is really interesting.

I guess my parents living in suburbs, residential area basically meant to use electricity over gas.

It would be interesting to see if this current shortage, is going to accelerate the transition to electricity. Although retrofitting older building might be very expansive. But if gas price continues to increase like it did in the past few months, it would change the equation for some.
