I have no idea whether they'd be able to compete commercially, but they manage to put a lot of money in a pension fund for all Norwegians: https://en.wikipedia.org/wiki/Government_Pension_Fund_of_Nor...
I wish BP and Shell did the same instead of being "commercially competitive".
If no one buys into their wind farm, there won't be much money to put into the pension fund (I mean it will, they earn money form oil, but no "wind money").
