Question

why should coal and petroleum be used carefully? how can we conserve these fields

Answer 1

Coal and petroleum were formed millions of years ago. They both have innumerable advantages like coal is used to manufacture coke, it is used to generate electricity and it is being used for industrial purposes as well. On the other hand petroleum is used for cooking, it is used as a fuel and for making paraffin or wax. Hence coal and petroleum are very advantageous. As they both are among the non renewable resources so they must be used wisely, because the survival without these two fossils will be very difficult.

By the following ways we can conserve coal and petroleum

1. using alternative sources of energy, especially for cooking.

2. using bulbs of CFLs instead of regular bulbs.

3. carpooling or using public transport to travel.

4. when car is at traffic signal, switch off the engine, to save fuel.

5. using air conditioners or heaters only when needed.
