a)

2. There would be no fuel for transport.
3. There would be no fuel for running machinery.
4. There would be no fuel for producing electricity.
So life on earth become miserable.
b) The future energy resources are hydro electric power, solar energy, wind energy, tidal energy, geothermal energy, Ocean Thermal Energy Conversion (OTEC), biomass energy.
c) No, a survey gives an information that about 2015 the world people would consume half of total reserves of petroleum. Coal also exhaustible resource. We can meet our needs with coal for another 250 – 300 years at the current rate of use.
d)
1. Do not waste fuel for unnecessary activities.
2. The energy should be properly utilized and the wastage should be minimized.
3. Usage of bicycle in place of motor vehicles for small distances.
4. Using road transport vehicles for travelling larger distances which will minimize fuel consumption.
5. The engine of a vehicle thoroughly serviced in order to minimize fuel consumption.
6. Alternative sources like solar energy, wind energy, tidal energy more utilized.
