Using appealing cartoons with a cast of lively and curious kids, experts Malcolm Wells and Tilly Spetgang demonstrate how solar power works in a wonderfully clear and understandable way. The fun lesson unfolds in a classroom where students explore solar energy and today s technology: active systems, passive solar, and the conversion of sunlight into electricity. In addition to learning why the sun is superior to nonrenewable fuels, young environmentalists will discover the many cool things you can do with this clean and natural energy. And it s all spiced with irreverent humor that makes the complex subject not only easy to grasp, but delightful. Plus, for their adult friends and relatives, it is a simple and clear lesson on the need for solar power in this environmentally challenged world we live in.
