The Human-Powered Home is a level-headed book which focuses on informing and entertaining. There is no utopian hyperbole, just useful facts and anecdotes that provide the foundation necessary to take appropriate action. Dean has produced an accessible primer for novices in the area of people power as well as a book that is thorough enough to benefit even experienced tinkerers.
