> Meanwhile, back in the real world not only are power grids distributed at a continental level but there also multiple sources of power feeding into that grid, including imported energy generated from renewable sources.

There is nothing close to the grid capacity to make this statement true.

Germany lacks base load capacity and imports energy from coal and natural gas burning neighbors when their renewables go offline. To offset this, Germany is building more base load capacity in the form of gas driven plants. This isn't a secret, it's not disingenuous to point it out.

The better option, from the point of view of carbon neutrality, is to make up that availability gap with nuclear. The Germans are unwilling to do this, and likely they hope that eventually they can import energy from neighbors that are willing to make up this gap with nuclear plants the Germans themselves were unwilling to build.
