Woody Harrelson—Volkswagen “Beetle,” $15K

Woody Harrelson isn’t just an actor; he’s a bona fide green activist. A throwback to the earth-loving hippies of yesteryear, he takes a conscious step forward with his iconic VW “Beetle.” Rather than succumbing to standard, pollutant-laden diesel, he opts for B100—fuel made from 100% biodiesel.

When he’s not cruising around in his eco-friendly Beetle, you’ll find him biking across the lush landscapes of Hawaii, where he spends much of his time. Arrested once for protesting against the logging industry in San Francisco, Woody’s activism isn’t limited to fuel choices. His car, like his life, is a testament to green living.
