[Energy for the 21st Century] is about the most intelligent, most sophisticated, most clearly-written book for children about energy I have yet to see. The author does an outstanding job of describing just about every scientific and technological aspect of the present debate about energy use in this country (and, maybe, the world). My only concern is that no attention is given to the political, social, economic, and ethical issues involved in energy production and use. I can hardly criticize an author for a book he didn't intend to write, but anyone who takes such a sophisticated and intelligent approach to this topic perhaps might at least consider the enormous non-scientific factors involved in energy production and use.
