Burning fossil fuels, such as coal, oil, and natural gas, generates most of the power that we use today. This book explains how these fuels formed and why we must approach our use and production carefully as this is a finite source.

In this book, young readers will learn about passive solar power, photoelectric conversion, and how often they encounter solar energy use in their everyday lives—oftentimes, without even knowing it. Students will see the sun in a whole new light.

Though wind power has been in use for hundreds of years, it’s one of today’s fastest-growing energy sources. Readers will learn how we have harnessed the wind’s energy with everything from primitive windmills to high-tech wind farms.

This fact-packed book offers a simple, age-appropriate explanation of nuclear energy, discusses fission and fusion, and explores the pros and cons of this important energy source. A timeline is included to provide a full historical view of our challenges and advances in nuclear power.

Eco-conscious readers will be thrilled to know that one of the most powerful, renewable sources of energy has nothing to do with burning fuel or releasing of pollutants, and has a very minimal production of green house gases. Students will see how we’ve harnessed the power of nature and water to create hydropower.

We use Earth’s internal heat to do everything from producing electricity to heating our buildings. Readers will learn about the sources, harnessing, and workings of geothermal energy, and what the future holds for this reliable renewable energy source.
