Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Wind power generation depends on cube of wind speed.
Reason (R): Kinetic Energy of wind is proportional to the square of wind speed.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

For wind energy numerical problems, always remember the important relation: \[ P = \frac{1}{2}\rho A v^3 \] A small increase in wind speed causes a very large increase in generated power because of the cube relationship.

Answer 1

The Correct Option is B
