Energy from Water: Hydroelectric, Tidal, and Wave Power

Nancy Dickmann (author)

Publisher: Crabtree Publishing Company ISBN: 9781427117571

For centuries, falling water has been used in parts of the world to create energy to run grinding stones at mills and irrigation systems for crops. This interesting book shows how the use of this “clean” form of energy, called hydroelectricity, is being expanded to help us build a more sustainable future. Discover how other forms of water-based energy, such as energy from ocean waves and tides, are being harnessed and used to help create electricity to power our homes, offices, and factories.

From Sunshine to Light Bulb

Michael Bright (author)

Publisher: Crabtree Publishing Company ISBN: 9781427118172

What happens when you flip a light switch or press the power button on the TV? Electricity flows to the device and it turns on. Most of us use electrical gadgets all day, every day, without thinking about it. This book follows the journey from source to resource of solar power, one of the most exciting forms of renewable energy today. Readers will learn how electricity is made and collected directly from the sun and how it reaches us to power our modern world. Other sources of energy are also examined, as well as how grids work to move electricity across land and sea, and how it is fed into our homes. Real-world examples look at solar farms, solar furnaces, solar towers, and even solar transportation. With the world's nonrenewable resources such as oil running out, the advantages and disadvantages of solar power as a renewable alternative are discussed.
