| Convert Used Cooking Oil into BiofuelIn America, people are helping to advance in renewable energy by just donating their used cooking oil that would be later turned to biofuel.In San Francisco, a cooking oil drive was held to help power the city's biofuel vehicles. The event generated about two tons of used cooking oil. Converting these oil into something useful can help on more ways; it supplies biofuel for vehicles and save millions each year for repairing pipes damaged from people pouring old cooking oil down the drain.
