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 resources?
Now imagine that you are living in the same place in the year 2138. Can you put explain why the wind is an important resources now?
In pre-historic times, wind was not considered to be a resource which could be put to much use. Me and my friend could use wind to fly our kites high.
In the year 2138, wind would be an important source of energy. It would be used to produce electricity through wind mills. It is an important resource now.
