Question : Which of the following is not a commercial source of energy ?
Option 1: Coal
Option 2: Petroleum
Option 3: Natural Gas
Option 4: Firewood
Correct Answer: Firewood
Solution : The correct option is Firewood.
Firewood is not a commercially viable energy source. While firewood is utilised for heating and cooking in many households and communities, it is rarely marketed on a wide scale as a commercial energy source. Coal, petroleum, and natural gas, on the other hand, are generally recognised as commercial sources of energy and are widely used for power production, transportation, and industrial reasons.
