The comparison between two old technologies doesn't give any clues for the future. The argument to continue using nuclear energy since there are better energy sources like solar and wind power. Germany shut down eight nuclear reactors after the Fukushima accident. The cost of electric energy did decrease and Germany exports more electrical energy than ever before, despite Cassandras that it would all break down without nuclear. The comparison should be between nuclear and a mix of renewable and modern, efficient gas power plants.

One obvious difference - in the NASA image, clouds have no shadow, in the russian one they do. That makes the NASA image look flat, and the russian one jump out in 3D. Why that is, I'm not sure.

The Russian image is taken at the day-night border, where the sunlight comes from the side, while the NASA image is taken around noon. The shadows make the landscape much more visible. Spy satellite images are often taken in the morning or late afternoon for the same reason.
