Reply to comment by Akiasakias in Germany exported more electricity to its neighbours than it imported in 2022, even with an energy crisis at home, thanks to more weather-driven renewable power and greater demand from France by green_flash

That is wrong. Transmission lost would be terrible over this distance, the lost of power rises exponatial over distance. More then "a few percent". You also don't calculate in your "investment" the cost of building these land lines. What land lines do you want to build for that? Over- or Underground? If you go underground then the lost is even worse and good luck building 2000km of multiple overground landlines trough Europe without massive delays through politics and policies.

Also still waiting on the math you did, which the greens can't do and you did!

Will have to circle back Saturday with the data. I'm currently 2000 miles from home. Small town with limited internet and no access to my files.

Best I can do from my snow bunker are resources like this. https://globalsolaratlas.info/map?c=11.523088,8.261719,2

Red or orange, solar is great economic and environmental.

Yellow it is probably break even. Worth doing for environment reasons. But may not be a great investment.

Green or worse you are probably never going to make back the carbon debt of blast furnacing the silicon into panels.

Yeah still nothing about how to get the energy from Spain to Germany and the econmical effect of that.

What does it help the German energy grid if you produce the power in Spain? How does that help the supply?

Since you always talk about investement may think about the the macroeconmical factors for Germany to build and invest in their own infrastructur. You see this very one dimensional, more sun = more money. Nothing is that simple.

No that is your interpretation and it is wrong. The colors show the output, which is in southern Spain 40% higher then in Germany. Sorry but your source does not even help your point.

The one thing i still can't see is your math ;)
