Model Answer
Energy is required for all kinds of activities in daily life, industry, agriculture, transport and commerce.
Examples:
- Cooking and heating: Energy in the form of firewood, LPG or biogas is needed to cook food and provide heat in homes.
- Lighting: Electricity is required to provide light in homes, offices and streets.
- Transport: Energy derived from petroleum is used to propel vehicles like buses, cars and trains.
- Industries: Machinery in industries is driven by energy from coal, electricity or natural gas.
- Agriculture: Energy is needed to run irrigation pumps, tractors and other farm equipment.
Energy is generated from conventional sources (coal, petroleum, natural gas) and non-conventional sources (solar, wind, biogas). As consumption rises steadily, judicious use of energy resources is essential.

Explanation
- The examiner expects at least 4–5 distinct examples with brief explanation for each — this question is directly from the textbook definition plus supporting details.
- Mention both conventional and non-conventional sources briefly to show complete understanding.
- Avoid writing a long essay; use a short intro + point-wise examples + one concluding line — this fits the 5-mark word budget neatly.
- The exact phrase "cook, provide light and heat, propel vehicles, drive machinery" comes directly from the textbook — use it as your base and expand slightly.
