Question 23
Select the eco-friendly activity among the following
(a) Using car for transportation
(b) Using poly bags for shopping
(c) Using dyes for colouring clothes
(d) Using windmills to generate power for irrigation

Answer 1

Option (d) is correct.
A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. Centuries ago, windmills usually were used to mill grain, pump water, or both. Since there are no pollutants coming out so it’s eco-friendly.
