I did start my comment with 'Aside from Belgium', but you're right about the Netherlands.

Checking its energy mix now, it looks like it has even less hydroelectricity than Belgium.

Somewhat true. I got the hydroelectricity generation wrong for Denmark and the Netherlands, so my point is only really correct for half the list, as you said.

But it's not just about the surface being flat.

Still, Norway and Sweden have some of the highest hydroelectricity generation worldwide. With Finland a little behind, but holding strong at top 40 globally.

Norway is an abundant oil producer.

Exactly my point.

In these countries, tax policies are used to steer towards electric vehicles for environmental and national security reasons.

Aside from Finland and maybe Belgium, none of these countries care about the environment. If they did, Norway, Denmark, and the Netherlands wouldn't be among Europe's biggest crude oil producers.

We really need to stop glazing the Nordic countries as if they were some utopias completely free of crimes, where governments wanted the best for everyone.

Most of their successes are simply due to circumstances outside of their control, and paid for by poorer countries.
