The heat map shows an effective sunshine amount per person. The red areas have plenty of sun, while purple areas have little sunshine per person.
Sun is the source of life on earth. We use it for agriculture and increasingly for electricity generation. In the long term, humanity will rely completely on the renewable energy, where the sunshine will be the most valuable natural resource. Here, I look at the regions which have the greatest amount of the sunshine per capita. Three continents stand out: Australia, Africa, and South America. They have plenty of sun for their populations. In the future, the extra sun will increase their wealth or perhaps sustain much larger populations.
