Chiras, Daniel D.: - "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 Earth.

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 Sp
