"If someone wants an overall view of how energy gets used, where it comes from, and the challenges in switching to new sources, this is the book to read." - Bill gates, Chairman, Microsoft.

"A tour de force... As a work of popular science it is exemplary... For anyone seeking a deeper understanding of the real problems involved it is the place to start." - economist.com

This book is an essential resource for understanding energy policy as it relates to conservation and to renewable resources. This is how environmental science should be communicated; crystal clear text and honest graphs, with simplified theory and ballpark calculations that anyone can follow, backed up by empirical data as a check on results. Real examples, frequent references and explainations of limitations.

This book puts real numbers to a lot of hand-waving arguments which are used to justify grandiose claims made for different renewable energy sources or to imply that we could save the world if we all just unplugged our mobile phone chargers.
