As oil prices continue to rise, many people are starting to think about how to unhook from the power grid. The Renewable Energy Handbook focuses completely on off-grid, sustainable living and energy independence in a rural setting.

Author William Kemp and his wife designed their own high-efficiency off-grid home in 1991. They worked methodically to produce a home which has all of the standard "middle-class" creature comforts while using six times less heating, cooling, and electrical energy than the average Ontario home. Soon they were inundated with inquiries and decided to put their experience into book form in 2003.

This updated edition focuses specifically on off-grid concerns and contains chapters on:

• Energy conservation
• Heating and cooling
• Photovoltaic, wind and microhydro energy generation
• Battery selection, voltage regulation and inverters
• Backup power

Twice the page count of the first edition, it also includes enhanced chapters on home and domestic water heating, wireless communications and biofuels. A "Showcase of Homes" chapter provides a tour of various off-grid cottages and homes, and details the type of lifestyle that can be achieved for a given capital cost. The book is augmented with appendices and hundreds of illustrations, line drawings and photographs.

William Kemp is VP Engineering of Powerbase Automation Systems Inc. and a consulting electronics/software designer who develops control systems for low environmental impact hydroelectric utilities worldwide. He is a sustainable living and clean energy advocate working in renewable energy heating, energy efficiency, photovoltaic, microhydro and wind electric systems.
