Neil Young: Veggie-Fueled Touring

The rock 'n' roll veteran helped pioneer the now-popular practice of fueling tour buses with biodiesel. When promoting his 2004 film and album, both titled 'Greendale,' Young traveled with a caravan of 17 diesel vehicles, all of which ran on a mixture of soybean and vegetable oil. The biodiesel fuel emits about 75 percent less pollution than regular diesel fuel. Others who've followed in Young's Earth-friendly footsteps with their own biodiesel-fueled tours include KT Tunstall, the Indigo Girls and Keith Urban, just to name a few.
