The earth gives us many things: air, water, shelter, food and energy. We cannot live without these, but we have to use them carefully, to make sure they last, and that we do not harm the world around us.
The world cannot work without energy. Living things need food, while machines use power in the form of electricity or petrol to make them work.
'Earth Alert! Energy' tells you about:
- Power that comes from the sun
- Getting energy from wind and water
- How using energy may be changing the weather
- Ways that you can save energy at home and at school
This book is full of interesting examples, facts, activities and colour photographs. It is a fascinating study of managing energy, both now and in the future.
