With the market saturated with titles for middle-grade readers about alternative energy, a new book must set itself apart, and this one does. Written by an environmental activist whose own interests in saving the earth began when he was a teenager, this title gives many opportunities for readers to think about how they, too, can impact the world around them. Features include appealing cartoon illustrations, lush photographs, projects that let students explore how various types of energies work, profiles of kids active in environmental issues, strong explanations, and more. Highly recommended. (102) ( )
