Nuclear is pretty expensive though. Nice and constant yes.
Yesterday it was nicely compared in an episode of Fully Charged. They are comparing the British Hickley point C nuclear project with a new project near South Korea, which will become the biggest windmill project in the world (8 times the current biggest one)
The wind farm at sea is muuuuch cheaper than nuclear. At least in that comparison.
In the end, in a world without subsidies, it will jut be a cost driven thing. Just like it is (or was) cheap to run coal. If nuclear is more expensive than renewables than not many will do it.
