Winona LaDuke runs her car on biodiesel and vegetable oil, and hopes to spread this practice to the fleet of tribal vehicles on the White Earth Reservation. "In my reservation in Minnesota, we have a casino which produces l0,000 gallons of grease - that's a good start for our tribal school buses and the like," she told Sundays Energy in July 2006.
"In my reservation, the main thing I work on is how you build a self-reliant, culturally revitalized community that's going to survive in the post-petroleum economy. And the reality is that in the largest energy economy in the world, you've got to transform the economy to a renewable economy." In 1996 and 2000, Winona ran for election to the office of Vice President of the United States as the nominee of the United States Green Party, on the ticket headed by Ralph Nader.
