I would like to acknowledge the editorial assistance of Wynn-Anne Mourre and Shelley J. Leonard in preparing this manuscript, and I thank them for their help. My daughter, Renee Clayton, assisted with the cover design.

Dedication: I dedicate this book to my grandchildren, Alexander, Kristiana, Anne and Lucy Clayton. I wrote this book for them. They are the future, and I want them to know there will be plenty of energy for them to use and that the environmental impacts can be mitigated.
