^^^ I had one of those growing up and thought it was so wonderful to see all that information all in one place. the amount of information displayed in a easy to see format conveyed an enormous amount of data. For its day it was an expert use of graphics to display multiple levels data all at once.
Despite being an unusual form of a gridded cartogram, it gives insights into the human geography of the world’s population. The four traditional physical hemispheres, dividing the world into north, south, east, and west, become almost irrelevant and are replaced here by a new division. The population centre of the world is situated on top of a mountain next to the Tiger Lake (Badai Talai) near the city of Udaipur. That point, displayed in the map’s centre, stands symbolic for the effects of recent demographic changes in the world population. The global population centre is gradually shifting from the currently most populated region in Asia towards a most rapidly growing African continent, which pushes the signifi cance of Europe and the Americas literally towards the edges of the planet in this modern version of a mappa mundi.
The data is a decade or so old, but the graphic is cool.
Gotta insert the standard note about this being primary energy supply, which means the hydro and the solar and wind part of other renewables are doing 3x as much useful work as the combusted fuels and nuclear energy. Which is to say, it'll only take about a third as much of those fuels to replace the rest.
