What makes our car go and our lights glow? Energy! Learn about clean, renewable power made by the sun, wind, water, and the earth. Esther Porter grew up in North Dakota, where she and her best friend had enough small animals to open a zoo. She is the author of a number of science-y books including What's Sprouting in My Trash? A Book about Composting and Sun Power: A Book about Renewable Energy. Her only animals now are Chopstick the angry cat, Georgie the confused cat, and Samantha Turkey Porter the slobbery pup.
