I live in a 100 year old, poorly insulated house with my family of 4, and we manage to use half of the average for a family house here. And we are not really trying, only thing we do is limit what parts of the house we heat (not the bedrooms) and set the temperature smartly.
I cycle 30km to my work on an electric bike to exercise and limit car usage.
So yes, I really don't think the price rise will have too much impact on consumers directly. I think most people in the Netherlands can halve their energy consumption here with very limited impact on QoL just by heating less and using their car less. And if the price really gets problematic our gov could just lower the taxation
