Norwegian here.

- We have a lot of hydro, that are very cheap to produces and for some of the power plants we fill up water by using solar and wind when that is very cheap and generate power back when it's demand for it (meaning selling it expensive)

-Norway export more then we are importing. But that could shift in the coming years.

-Nuclear power are expensive, so with the current prices it do not make sense to have nuclear in Norway. Thought that could change (see point 2)

- not sure what you mean by "little land usable", you can absolutely be correct. in terms of size we are bigger then Germany. But I'm not sure how much usable land there is vs other countries. We do not have that big population but it's spread out and no one wants a wind park in their neighborhood
