From Booklist
This offering from the Eye on Energy series, part of the umbrella Checkerboard Science Library, begins with an explanation of the internal-combustion engine and its shortcomings. Wheeler then introduces readers to more efficient methods of powering automobiles, including electricity, a combination of gas and electricity, diesel fuel, hydrogen, natural gas, and ethanol. For each alternative she describes advantages, disadvantages, and the current availability of this technology. Captioned, full-color photographs, mostly of prototype vehicles, appear on nearly every page, complementing the clearly written text; unfortunately, a futuristic-style border intrudes into some of the photos and detracts from the otherwise clean layout. Wheeler is careful throughout not to favor any one alternative or to chastise Americans for their dependence on cars; this restraint makes sense, given how few of the options she cites are ready for production. A good choice for classrooms studying energy resources or for interested browsers. Grades 3-5. --Kay Weisman
