Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The high initial cost of wind mills makes wind power unsuitable for sustainable development.
Reason (R): In areas where the speed of wind is usually high, wind mills can provide electricity without any adverse impact on the environment.
In the light of the above statements, choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A) is false but (R) is true.
Assertion (A): The high initial cost of wind mills makes wind power unsuitable for sustainable development. — False. The initial cost is high, but the benefits are such that the high cost gets easily absorbed. Wind power is one of the strategies for sustainable development.
Reason (R): In areas where the speed of wind is usually high, wind mills can provide electricity without any adverse impact on the environment. — True. In high-wind areas, wind mills give electricity with no adverse impact on the environment.
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.” |
