In Oslo, battery electrics are 49% [2]. We’re just starting to see its gas stations shut down [3].
Norway as a whole should hit 50% before 2030. By that time, Oslo should be around 3/4 to 4/5 electric. That should show the threshold at which gas infrastructure starts economically collapsing and forcing last-mile adoption through pricing. (China should hit 50% in the 2030s. The world, in the 2040s. So Norway shows us what being a gas laggard should look like in twenty years.)
