Just a note about district heating: it's not majority of all housing (market share somewhere around 45 %), but it is majority of new housing (around 60 %).
And saunas are heated with electricity in towns, although a few old public facilities still run on wood stoves, as well as private saunas of those who like the "pure" feeling (such as myself).
