Energy for Life gives the reader a detailed study of the role of energy in the world today. Topics covered include different energy resources and their uses, how fuels were formed, how they were discovered and how their use is changing, now and for the future. The series examines how energy can be transformed from one state into another and the conservation of energy. Each book in the series emphasises renewability and sustainable development of the world's energy resources. (The same concepts are covered in the parallel series Essential Energy which is aimed at a higher reading level.)
