The initial cost of setting up wind mills is high. Why is wind power still seen as a good strategy for sustainable development?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Its benefits are such that the high cost gets easily absorbed
Wind mills cost a lot to set up. But they give electricity without any adverse impact on the environment, and these benefits easily absorb the high cost.
Option (1) The government provides wind mills through easy loans and subsidy — Incorrect. Easy loans and subsidy are given for gobar gas plants.
Option (2) Its benefits are such that the high cost gets easily absorbed — Correct. This is why wind power is still a good strategy.
Option (3) Wind mills mainly supply a clean cooking fuel to rural households — Incorrect. Wind mills produce electricity. Clean cooking fuel for villages is LPG.
Option (4) Wind mills do away with the need for transmission towers and cables — Incorrect. This is a benefit of mini-hydel plants, whose power is used locally.
NCERT (2026-27): “7.5 Strategies for Sustainable Development … Wind Power: In areas where speed of wind is usually high, wind mills can provide electricity without any adverse impact on the environment. Wind turbines move with the wind and electricity is generated. No doubt, the initial cost is high. But the benefits are such that the high cost gets easily absorbed.” “… To rectify the situation, subsidised LPG is being provided. In addition, gobar gas plants are being provided through easy loans and subsidy. …” “… This means that they can also do away with the need for large scale transmission towers and cables and avoid transmission loss.” |
