Answer 1

Answer:

We know that coal and petroleum are fossil fuels. If they are used once they cannot be renewed easily in short period of time,they will take millions of year to renew as they are exhaustible resources.So they should be used judiciously to ensure their availability for a longer period of time.

Answer 2

most of the energy that we use today come mainly from three exhaustible resources on the earth- Coal ,Petroleum and natural gas the amount of Coal Petroleum and natural gas present in the earth is limited. the known Reserve of Coal Petroleum and natural gas will last only for about hundred years. once the present stock of Coal Petroleum and natural gas in the earth get exhausted no new supply of these fuel will be available in the near future because it takes millions of here to convert dead organic material into fossil fuel in nature so fossil fuel should be used with care and cautions and not wasted and also that the existing Reserve of fossil fuel can be used over a long period as possible.
