ings who live in accordance with the laws of physics, botany, and biology, people who truly want to
master the art of living as contrasted to a life of taking. Te best manual you could possibly want.

First there was the Whole Earth Catalog, and then there was the Real Goods Solar Living Source-
book, and now. . . there is still the Solar Living Sourcebook. Now in its 14th edition, the Sourcebook
continues to be jam-packed with exciting ideas and innovative products to make the good life a
practical reality. Always a classic, but now even better.
—Stephen Morris, Publisher Green Living Journal and founder of Te Public Press
Te Solar Living Sourcebook, long a trusted source of accurately described energy-efcient products,
has evolved into this remarkably comprehensive textbook for an education in Sustainability. You’ll
not only see what’s available, but how to think about your choices as you learn the why and how
to develop a lifestyle with minimal environmental footprint. Bucky Fuller wrote, “Philosophy, to
be efective, must be mechanically applied.” Here’s the philosophy and most everything else you
need to do so.
—Jay Baldwin, Senior Adjunct Professor of Industrial Design
and Sustainability, California College of the Arts (CCA) San Francisco
For all those dedicated to sane, reverent common sense — and to those not yet, here is a comprehen-
sive, rousing guide to a renaissance of reverent ingenuity. Critique holds up a necessary mirror to
our world — “look — ack!”, with a wave of the hand we change the mirror into a window — “look how
beautiful it could be!” then with another wave of the hand — the window becomes a door — “let’s
go and here’s how!” John Schaefer’s Solar Living Sourcebook does all three. Let’s spiral this forth to
libraries, schools, neighborhoods, elected ofcials — at this time of dire beauty.
—Caroline W. Casey, “weaver of context” for Te Visionary Activist Show radio show,
founder of Coyote Network News, a mythological news service
for the Trickster Redeemer within us all.
At a time when the Earth and its inhabitants are facing unprecedented challenges, John Schaefer’s
14th Edition Solar Living Sourcebook ofers an excellent comprehensive roadmap to sustainability.
Reminiscent of Te Whole Earth Catalog, which helped lead a generation to Earth friendly alter-
natives to conventional practices, Te Solar Living Sourcebook is much more valuable and speaks to
our vexing 21st Century issues. Te complex problems we face can only be solved with a full menu
of synergistic solutions. Tis book goes far and deep in laying the foundation for sustainable living.
Globally we all live in the same neighborhood. By demonstrating what works, what is afordable,
and what is sustainable, we can show, by example, and lead the way to a greener and brighter
future for all of humankind. A greener future is ours alone to make. Tis book is an essential step
in leading the way. Future generations are depending upon us now to make ecologically smart
decisions and this book is an essential frst step.
—Paul Stamets, D.Sc., Fungi Perfecti, and author, Mycelium Running
Te solar photovoltaic cell — a unique California success story — was only 24 years old when John
and his team at the Solar Living Institute frst published this veritable bible of sustainable living.
Today, hundreds of thousands of Californians have followed in John’s footsteps, installing two
nuclear power plants worth of solar power on roofops from Humboldt to San Diego. Other states
and countries now give California a run for its money in this race to the top where everyone wins.
Whether you’re an of-grid, hay-bale house, zero-carbon-footprint enthusiast or someone who’s
just interested in saving a little money with a home solar electric or hot water system, this is the
resource book for you.
—Bernadette Del Chiaro, Executive Director, California Solar Energy Industries Association
Te Solar Living Sourcebook continues to be the bible for practical uses of commercially- available
solar, energy efciency and other clean energy options. Now that more people than ever before are
turning towards solar energy options, to me, this is the frst resource to start with.
—Scott Sklar, President Te Stella Group, Ltd.
