LPG is a clean fuel that reduces household pollution to a large extent. Which other benefit of LPG does NCERT mention?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Energy wastage is minimised
Besides reducing household pollution, LPG also minimises energy wastage.
Option (1) It leaves a slurry that is used as manure — Incorrect. The slurry is left by a gobar gas plant.
Option (2) Energy wastage is minimised — Correct. This is the second benefit of LPG.
Option (3) It is made from cattle dung — Incorrect. Gas from cattle dung is gobar gas; LPG is liquefied petroleum gas.
Option (4) It is supplied free of cost to every household — Incorrect. LPG is provided at a subsidised price, not free.
NCERT (2026-27): “7.5 Strategies for Sustainable Development … To rectify the situation, subsidised LPG is being provided. In addition, gobar gas plants are being provided through easy loans and subsidy. As far as liquefied petroleum gas (LPG) is concerned, it is a clean fuel — it reduces household pollution to a large extent. Also, energy wastage is minimised. For the gobar gas plant to function, cattle dung is fed to the plant and gas is produced which is used as fuel while the slurry which is left over is a very good organic fertiliser and soil conditioner.” |
