Correct answer: Biofuel crops

Biofuels are alternative fuels that come from plants and plant-derived sources. Biofuels are usually used for transportation. One such of biofuel is called the bioethanol, which can be used as substitute for petrol. It is produced by fermenting cellulose from corn (maize) and sugar cane. Another type of biofuel is the biodiesel, which can be sourced from oil crops like rapeseed, palm, and soybean.

Biofuel crops are considered as a renewable source of energy because it can be easily replaced (by planting the crops) in a relatively short span of time.
