To Choose: The correct option.
Answer to Problem 4STP
Option D
Explanation of Solution
Introduction:
Windmills are used to get the electric energy using the energy of wind. The propeller is used for conversion of wind energy into electric energy.
The wind energy is renewable and non-polluting form of energy that is the reason it is considered as clean form energy. They are highly efficient. Hence, the option (D) is correct.
The windmills can transform 100% of wind or air passing over it. Hence, the option (C) is incorrect.
The windmills are installed on that places where the wind is found in abundant quantity. Hence the option (B) is incorrect.
The windmills are not quiet because the moving blades are used to convert the wind energy into useful energy. Hence, the option (A) is incorrect.
Conclusion:
Thus, the correct option is D.
