Is the US still a coal-powered nation?

I ran across a map recently that seemed to show a lot of US states are primarily coal-powered. The map was a little difficult to read, so I decided to give it a SAS makeover ... Before we get started, here's a picture my friend David took of the Shearon Harris Nuclear Power

One of my favorite quotes is: "You can't believe everything you read on the Internet" - Abe Lincoln, 1868. And that is especially true when it comes to graphs and statistics. Hardly a day goes by without me seeing a bad graph that misrepresents the data (either intentionally or unintentionally) .
