Everyone needs the things Earth can give us - such as air, water, shelter, food and energy. But we must learn to use these carefully, without harming the world around us. Our Earth is in danger - and we must make it safe for the future.
The world cannot work without energy. We use it every day. This book tells you about power from the sun, and about getting power from wind and water. It also helps you find out about saving energy at home and at school.
