Which among the following fuels has the highest calorific value?
(a) Kerosene
(b) Biogas
(c) CNG
(d) LPG
Biogas has the lowest calorific value among the given fuels. Calorific value means the amount of heat produced to burn 1 gram of fuel. The raw materials used in the production of biogas, such as food, plant and animal waste are inexhaustible. So it is an inexahustible and a sustainable form of energy.
Option B is the answer.
