Can we use vegetable oil for fuel?

According to some estimates, out of nearly 23 million tonne (MT) cooking oil consumed in India, 3 MT can be used for the production of biofuel. Biofuel, produced from vegetable oils, recycled grease, algae, and animal fat can be used as an alternative in place of fossil fuels.

How is vegetable oil an alternative fuel?
