This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.
