Question

utility and value of resources vary from time to time and place to place give any three example to support the statement

Answer 1

Here are some examples:
1. High speed winds were not much useful few centuries ago. But after inventing windmills that generate electricity with the help of winds, winds have become a useful resource for the production of energy. They are a important source of energy in farms and countrysides.
2. Large uranium deposits found today are very difficult to use. It is because we dont have the technology to utilise them. But maybe a few years later, they can become a very useful resource.
3. Solar energy is a very useful energy resouce. However when there is no sunlight, we are not able to utilise it. We are currently finding it difficult to store solar energy in large amounts and use it when needed. So in future, we might be able to utilise solar energy more efficiently.
Hope they will be useful:)
