Biofuels such as bioethanol (which can be used instead of petrol), are made from corn and sugarcane, whereas biodiesel is made from vegetable oils and animal fats. The best types are second generation biofuels which are produced from sustainable sources rather than those grown for food.
Liquids remain the most important fuels for transportation because there are few alternatives that can compete widely with liquid fuels. With world oil prices remaining relatively high through 2030, the increasing cost-competitiveness of nonliquid fuels causes many stationary uses of liquids—that is, electric power generation and use in the industrial sectors—to be replaced by alternative.
