DALLAS – Julia Roberts is making another debut: this time as a spokeswoman for alternative fuel.
Dallas-based Earth Biofuels announced that Roberts will become a spokeswoman for the company and chair its new advisory board.
"It's very important that we expand our use of clean energy and make a long-term commitment to it. Biodiesel and ethanol are better for the environment and for the air we breathe," Roberts said in a statement released this week.
Earth Biofuels produces biodiesel and is the exclusive distributor of Nelson's signature brand of biodiesel. The soy derivative is mostly sold in a blend called B20, which is 20 percent biodiesel and 80 percent diesel.
Earth Biofuels said it will work with Roberts on a program to encourage the use of biodiesel in more than 500,000 diesel school buses nationwide.
The 38-year-old actress made her Broadway debut this spring in a revival of Richard Greenberg's "Three Days of Rain."
Her screen hits include "Pretty Woman," "Steel Magnolias" and "Erin Brockovich" -- for which she won an Oscar in 2001. She gave birth to twins, Hazel and Phinnaeus, in November 2004. She is married to cinematographer Danny Moder.
