What are Biofuels?
Biofuels are fuels produced from plant material or living matter.
Coal and crude oil are non-renewable resources. They take so long to form that they cannot be replaced once they have all been used up. Petrol, diesel and other fuels produced from crude oil make a range of harmful substances when they are burned. Biofuels don't take as long to grow and can be grown in groups.
Examples of Biofuels:
Biodiesel- It is made from rapeseed oil and other plant oils. It can be used in diesel-powered vehicles without needing any modifications to the engine.
Bioethanol- Ethanol, C2H5OH, is not a hydrocarbon because it contains oxygen as well as hydrogen and carbon. However, it is a liquid fuel that burns well. Bioethanol is made by fermenting sugars from sugar cane, wheat and other plants. Needs engine modifications to work.
