Changing constantly, the protean forms of energy tend to be fugitives from observation compared to the visible, tangible features of Earth's environment. In this descriptive tour of energy on Earth, its sources, transmutations, and dissipations, Pielou adopts a style of graceful perceptiveness familiar to readers of her " Fresh Water" (1998). Conversion is the leitmotif of the energy story, and following the forms that energy assumes carries Pielou through the arenas in which the change occurs, such as the atmosphere, the land and sea surfaces, the oceans, biota, and Earth's interior. Except for a tiny fraction generated by radioactive decay and gravitational contraction in the core, solar radiation provides all of Earth's energy. Its passage through the atmosphere to the surface initiates the thermal, kinetic, and potential energy (the energy stored in objects liable to falling) drives wind and currents, further stirred up by friction and the Coriolis effect. Pielou incorporates easy arithmetic that conveys the scale of these interactive processes and deepens the understanding an attentive observer will derive from her guidance.(Reprinted with permission of Booklist, copyright 2001, American Library Association.)
