You don't even have to go to the issue of climate change to defned this anymore. The far more relevant factor is the cost of energy as well as national security.

Europe as a whole has engaged in greenwashing where instead of really solving their emissions and energy problems has simply offshored those problems to poorer countries. If a neighbour uses fossil fuels for electricity generation and you buy their excess electrricity, you're not greener. You've just cooked the books.

People who might say "when I go outside at this very specific place solar panels look ugly" should carry no weight when those solar panels (in Denmark's case) covers 0.2% of rural land. Go somewhere else.

Unsurprisingly, China is leading here by making solar panel installations have multiple uses like reversing desertification and use vegetation growth from the shade and the water used to clean the panels as a place for grazing livestock. Obviously Europe in general and Denmark in particular doesn't have deserts, of course.

I'm generally a fan of putting solar panels on non-arable land. In the US, that's much of the southwest, which incidentally also has very good solar yields because of the high amount of sunshine. There are whole areas of grass plains that can't be used for traditional farming as we discovered in the 1930s. It was called the Dust Bowl. There was a famous book written about it (ie the Grapes of Wrath).

What I don't understand is why we don't build more solar around or over highways. This is already public land and it's land not doing anything else. The solar wouldn't interfere with the core purpose either. I guess people want solar panels tucked away where few can see them.
