WHERE WILL TOMORROW’S
ENERGY COME FROM?

     Many concerned people are asking this question today . . . with good reason. Two of our most important sources of energy, oil and natural gas, are in short supply. We must find new sources of energy that can serve our needs in the years ahead.

     The search for alternative energy sources is a worldwide effort. Scientists working in industry, at universities, and in government research laboratories are trying to unlock new supplies of energy. For although our planet has abundant reserves of energy, enough to last for countless years, much of this untapped energy is locked away beyond our present reach.

     But we’re learning more about alternative energy sources every day. In the not-too-distant future, scientists will probably discover practical and economical ways to employ these different forms of energy.

     The eight experiments in this booklet will introduce you to several of the more promising alternative energy sources. A few of these include sunlight, wind, and geothermal energy. At the beginning of each experiment, you’ll find a brief introductory section that discusses the promises and problems of the particular energy source. Be sure to read it before you begin the experiment.

Good Luck.
