That does seem to head for electricity based heating. But a web search lead to some (admittedly 6 yrs old) graphs that have electricity being in in 3rd place after fuel based heating solutions by energy use: https://www.stat.fi/til/asen/2014/asen_2014_2015-11-20_tie_0... - and hopefully those new houses are better insulated and use proportionally much less energy than the average housing stock, eg passive houses.
