Norway is a hydro country.

More generally the global shift to renewables (solar, wind) is proceeding rapidly, but is hampered by politics: undertaxed or subsidized supply of very cheap natural gas and coal.

But we need both measures, shift to renewable electricity and scaling down car use, as EVs still have unsustainable co2 footprints.

I agree, Norway is in excellent position with hydro as its reliable baseline power source at the scale they have.

Other countries would struggle, and sadly the fission power-plants are demonized to the point of political suicide if you propose to build them. So globaly we are stuck with fossils until a miracle breakthrough in fusion (fingers crossed).

Even in nuclear friendly political climates, nuclear is just too expensive and unwieldy due to huge unit sizes, it had its chance in history but is now a dead end due to low cost and rapid improvement in cost per megawatt in renewables.

Renewables aren't on demand electricity for the most of cases. Or on required scale to run as baseline for a power grid.

The grid need a way to absorb spikes in renewables production (solar in the day) but also fill in during lows.

Nuclear fission is by far the safest and cleanest way when compared to fossils. Its hardly 'unwieldy'.
