This great video features Amory Lovins and his house in Snowmass, Colorado, by the Wall Street Journal. A quarter-century ago, in the wake of America's first energy crisis, the young scientist named Amory Lovins came to the Rocky Mountains and built himself a radical house based on a radical idea. The country could save both energy and money, he believed, by combining common sense and unconventional technology. Mr. Lovins did achieve substantial energy savings, and many of his innovations, from better insulation to multiple-pane windows to more-efficient refrigerators, eventually became familiar fixtures in American homes.
