Energy is the power that makes things work. We get energy from food, energy from the sun, energy from fuels such as coal and oil - and even from the wind. However, the world is having an energy crisis. Some of our fuels are running out and cannot be replaced. We are also harming the Earth and the atmosphere around it. Scientists believe that burning too many fuels is causing 'global warming' and is changing weather around the world. This book explains all the different kinds of energy, how they are produced and how we can use them more wisely. It also looks at what you, the reader, can do to help and start to improve YOUR environment today. Throughout, 'Fact Panels' give stark statistics to highlight the problems and 'Try This!' panels give the reader simple activities which they can do to investigate the issues. These books are also weblinked which means that the reader is directed to specially selected websites where they can find out more.
