English: Original JPG by Frank van Mierlo
Graphic is original and mine, it was however heavily inspired by the work of others; notably NASA, which has published an overview with similar data in a different presentation (e.g. see [1]). Energy at the crossroads by Vaclav Smil, MIT Press 2003 has a graphic on page 241 that is identical to the NASA graphic but he does not credit them so it is unclear who copied whom. Anyway this picture is mine and I am happy to submit is to the public domain. Please do credit me if you use it.
