हिन्दी में पढ़ें →Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Wind energy has high energy density.
Statement II:Wind energy is an intermittent source of energy.
ABoth Statement I and Statement II are correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct ✓ Correct
Correct answer: (D) Statement I is incorrect but Statement II is correct
Explanation
The first statement that wind energy has high energy density is wrong, since wind is a low-density, dilute source.
The second statement is correct that wind is intermittent, varying with weather and time.
Large swept rotor areas are needed precisely because wind carries little energy per unit area.
Output rises and falls with wind speed, so supply is not steady.
The high-density claim fails while the intermittency claim holds.
Storage or backup is paired with wind to smooth its variable output.
