Alternative Energy Sources by
Climate change and sustainability are important topics in the 21st century. Scientists have long warned that using fossil fuels to heat homes, power vehicles, and keep appliances running has negative effects on the environment, but there are many economic and social issues to consider when switching to alternative energy sources. Readers discover the debates surrounding various forms of alternative energy, the barriers that must be overcome in order to adopt them, and the benefits they can provide. Up-to-date statistics, annotated quotes from experts, full-color photographs, and informative sidebars help young adults form their own opinions about alternative energy sources.

Science and Sustainable Energy by
As early as the nineteenth century, a number of scientists recognized that fossil fuels like coal and oil are in limited supply and that burning them to produce energy cannot be sustained forever. In the decades that followed, new generations of researchers steadily perfected alternative, renewable energy sources intended to eventually replace fossil fuels. Today, those sustainable sources¿including solar, wind, and geothermal¿are rapidly changing the face of energy production around the globe.
