This is the book to read if you want to understand sustainable energy issues. The only part where it's weak is discussing the economics; I would have liked more material on the costs and how to make sure they're manageable. And yes, it's refreshing to see a book on this subject written by someone who can do enough math not to fall for nonsense.
