Question

Pretend that you live in the prehistoric times on a high windy plateau. What are the uses you and your friends could put the fast winds to? Can you call the wind a resource?
Now imagine that you are living in the same place in the year 2138. Can you put the winds to any use? How? Can you explain why the wind is an important resource now?

Mona and Raju were helping Amma to clean their house.“Look at all these things…. clothes, utensils, foodgrains,combs, this bottle of honey, books…..Each of these has a use,” said Mona. “That is why they are important,” said Amma. “These are resources…..”. “What is a resource?” was Raju’s question to Amma. “Anything that can be used to satisfy a need is a resource”, replied amma. “Look around you and observe, you will be able to identify many types of resources. The water you drink when you are thirsty, the electricity you use in your house, the rickshaw you use to get home from school, the textbook you use to study are all resources. Your father has prepared a tasty snack for you.The fresh vegetables he has used are also a resource”.

Water, electricity, rickshaw, vegetable and textbookhave something in common. They have all been used by you, so they have

utility

. Utility or usability is what makesan object or substance a resource.

“How does something become a resource?” Raju now wanted to know. Amma told the children that things become resources only when they have a value. “Its use or utility gives it a value. All resources have some 

value 

.” said Amma

Answer 2

We can use windmills to produce electricity. Therefore wind is a very crucial source of energy

Explanation:

• In prehistoric times we cannot put fast winds to any use, and as such wind cannot be considered as a resource during prehistoric times
• However, later, wind has been used since ancient times. It has been mainly used for navigation & for sailing boats. Slowly, wind mills were constructed to grind crops & to pump out water. Wind was considered as a potential resource. However because lack of technology it was not harnessed completely. First designs of windmills were built from wood, often rotated by hands or oxen to raise wind energy
• Nevertheless we have may use of Winds in 2138. In 2138 , we can see wind being used to the fullest as a resource. We have built wind turbines to generate electricity. We can see increasingly more wind turbines being used in agricultural farms to meet electricity & irrigation needs, and  industrial areas
