Indigo Girls
The Indigo Girls used B5 biodiesel as part of a tour focusing on alternative energy and Native American environmental issues. The two-week "Honor the Earth" tour began April 10, 2003 in Northfield, Minnesota, and wrapped up on April 22, Earth Day, in Greeley, Colorado.
The tour visited 8 college campuses, put on full-blown activist music events, and was able to mobilize thousands of students and communities around social justice issues and renewable energy. "We feel that biodiesel fuel and solar energy are important because they offer us a way to live peaceably and cleanly -- well into the future," said the girls in 2003. "These technologies also help to save our pristine forests and waterways from destruction."
