Energy consumption increases, but charging stations are ubiquitous and economic incentives plentiful in Norway. Geographic areas with colder climates frequently have block heater power available; similarly you want power available for "shore power" to keep the battery charging and conditioned when it's exceptionally cold.

Norway's electrical generation is almost 100% renewable, so the additional energy consumption is a moot point. EVs also make an excellent sink of power in aggregate ("controllable distributed load") for renewable generation that might have had to be curtailed and wasted.
