How do you appreciate the role of Ethanol as a fuel?

  1. A material which is burnt to obtain heat is called a fuel. Since ethanol burns with a clear flame giving a lot of heat, therefore it is used as a fuel.
  2. Some countries add ethanol to petrol to be used as a fuel in cars. Thus ethanol
    is used as an additive in petrol.
  3. Ethanol alone can also be used as a fuel for cars.
