This is a beautiful, extremely high quality PowerPoint presentation (suitable for posters) that consists of two slides that build to a total of four images:
Image 1: The world viewed from space
Image 2: The world viewed from space at night showing where the world's energy is being consumed
Image 3: The world viewed at night with an overlay of global population
Image 4: The same as 3, but with specific countries highlighted showing their percentage of world energy consumption compared to their percentage of world population
This is a very very interesting slide set that shows clearly how much energy Americans use compared to the rest of the world.
