Dan Chiras paid his last electric bill in June of 1996. It is not that he has disavowed the use
of electricity and modern conveniences, but rather that he has turned to the sun and wind
to meet his family's needs.
In 1995, Dan, a former full-time college professor with years of experience in sustainable
development, built a state-of-the-art rammed earth tire and straw bale home in
Evergreen, Colorado. He installed solar electric panels on the roof; a year or so later he
installed a small wind generator. Since that time, he has met nearly all of his electrical
needs for his home and office from these clean, renewable sources.
Dan also heats his home in the foothills of the Rocky Mountains 8000-feet above sea level
with energy from the sun thanks to passive solar design. For backup heat on those cold
winter nights, he burns a cord of wood a year, gathered free from his community. His
annual gas bill, mostly for showers and cooking, runs about $120 a year - about $2 to $3
per month for natural gas and $10 per month to read the meter!
Dan has spent much of the past 30 years studying sustainability and applying what he has
learned in solar energy, natural building, and green building to his residences, and most of
the last ten years sharing the practical knowledge he has gained through writing, lectures,
slide shows, and workshops.
Dan has published 21 books to date including several college and high school textbooks:
Environmental Science: Creating a Sustainable Future, Natural Resource Conservation,
Human Biology, and Biology: The Web of Life. His high school environmental
science text, Environmental Science, was selected as the official book of the U.S.
Academic Decathlon's 1991 competition.
In the early 1990s, Dan published two trade books on environmental issues and
sustainability for a general audience: Beyond the Fray: Reshaping America's
Response and Lessons from Nature: Learning to Live Sustainably on the
Since 1995, Dan has focused most of his attention on residential green building. He
has written extensively on the subject. His is books include: The Natural House: A
Complete Guide to Healthy, Energy Efficient, Environmental Homes; The Natural Plaster
Book; The Solar House: Passive Heating and Cooling; Superbia! 31 Ways to Create
Sustainable Suburbs; and The New Ecological Home.
His newest book, EcoKids: Raising Kids Who Care for the Earth will be
published in the Spring of 2005 by New Society Publishers.
Dan also writes extensively for magazines, journals, newsletters, and newspapers. He
has published nearly 250 articles on environmental issues, sustainability, natural building,
natural plaster, green building, and passive solar heating and cooling. His articles appear
regularly in Home Power, Mother Earth News, Natural Home, and The Last
Dan also writes frequently for World Book Encyclopedia (Science Year) and
Encyclopedia Americana. He authored a 12-page article on the environment for
Encyclopedia Americana. Dan has written environmental pollution section for
World Book Encyclopedia's annual publication, Science Year, since 1993.
In 1997, he wrote an extensive piece for World Book on population growth and its
many implications. Dan also wrote the ecology and air pollution sections for
In addition to his writing, Dan has served as an adjunct professor at the University of
Colorado in Denver and the University of Colorado at Denver. He has been a visiting
professor at the University of Washington, where he taught a course on environmental
science. He currently is a Melon Visiting Professor at Colorado College where he teaches
courses on renewable energy, ecological design, and sustainable development.
Through his writing and teaching in the 1980s and early 1990s, Dan played a leading
role in promoting critical thinking, an understanding of the root causes of environmental
issues, systemic solutions to environmental problems, sustainable development. He
pioneered a systems approach to sustainable development and has played a lead role in
articulating the principles, policies, and practices of sustainable development which seeks
ways that business and society can prosper within a healthy environment. He is currently
focusing most of his research and writing on sustainable building and sustainable
Dan's free time is spent mountain biking, canoeing, playing music, and gardening.
