Another "Funny" Ternary: Energy Sources

This occurred to me a few days ago, but it took me some time to decide how I wanted to lay it out. Based on 2010 data from Wikipedia.

Followup: I was actually a bit surprised at how much of the total went to renewables. If I'd had to guess, I'd have pretty much reversed that with nuclear. Also, adding "geology" tag. As I commented elsewhere, "where ever we go from where we are, the geology community and professionals will be the ones to allow us to get there." Whether petroleum/coal, nuclear or REE's, geology is going to be a significant part of whatever energy future we ultimately decide upon.
