I believe there are around 50 - 60 000 EVs in Norway and 6000 public charging stations. The EU is mandating that Norway needs to build 25 000 charging stations by 2020.

Shortage of charging points is becoming a problem as the number of electric cars is growing much faster than the building of charging stations. So while there is good geographic coverage the problem is that so many need to charge at the same time.

Whenever I pass charging stations down town they always seem to be occupied by somebody.

How can the EU tell Norway to build charging stations if Norway is not even a member of the EU? Do you have any sources for that?

Norway is part of the European Free Trade Association. It has access to the EU market but it means it has to respect certain laws and there is freedom of travel/work.

What happens with regular gasoline pumps there? 30% is a big number so I would expect some impact (closures, limiting working hours etc).
