NCERT Book Class 8 EVS Judicious use of fuels

8. Judicious use of fuels

Background

The known reserves of coal and petroleum will last, at most, a few hundred years. It is therefore necessary to use these fuels only when absolutely necessary. This will result in better environment and their availability for a longer period of time. In India, the Petroleum Conservation Research Association (PCRA) advises people on how to save petrol or diesel while driving.

Methodology

1. Survey at least 10 houses in your neighbourhood about the number of vehicles being used by them and how many people travel by these at a time. Find out if they share vehicles or go by separate vehicles.

2. Ask about the frequency of servicing of their vehicles.

3. Prepare a chart on the types of vehicles and the frequency of their servicing.

4. Ask about the driving speed of their vehicles. Procure booklets from PCRA and compare their speed with the speed advised by PCRA.

5. Ask about the average mileage being given by their vehicles.

6. Observe, at a busy road crossing, the average time for which vehicles stop. Every time the light turns  red, count the number of vehicles waiting for the light to turn green. Also note how many drivers switch off the engine of their vehicles while waiting at the traffic signal.

Conclusion

Make a brief report reflecting to what extent people are adopting measures for using fuels judiciously.

Follow-up

Prepare slogans on conservation of fuels and campaign for it in your neighbourhood.
