An Interesting Picture Book -- energy

My Light by Molly Bang is a picture book about how the sun's energy creates electricity using water power/dams, windturbines, solar panels and also discusses how plants use the sun's energy and how this created coal. The author includes a few pages of notes about electricity at the back of the book -- good for adults and older kids, for whom the picture book might be a bit simplistic. The author states within the notes that she had more but that her publisher urged her to shorten it, however, she's posted the deleted portion on her website, www.mollybang.com.
