Set in Houston, Texas in the shadow of the nation's oil industry, HOT GREASE tells the surprising story of how the biodiesel industry is turning an ostensibly worthless raw material-spent kitchen grease-into a green energy source capable of fueling all of the trains, ships and trucks throughout the country--if it can overcome the powerful forces working against it. Featuring innovators, entrepreneurs, grease collectors and supporters like Senator Al Franken, HOT GREASE follows the battle for biodiesel's future and it's very survival.
