Keeping in mind their availability in nature, Explain why should coal and petroleum be used
judiciously? Also, mention the alternative sources of energy.

Please find below the solution to the asked query:
Coal and petroleum are fossil fuels. It required the dead organisms millions of years to get converted into these fuels.
They should be used judiciously because :

1.they are fast depleting

2.they cause environmental problems

3.they are non-renewable

If they are not used judicially then these reserves would not be available for our next generation, Moreover, burning of these fuels is a major cause of air pollution. Their use is also linked to global warming. It is therefore necessary that we use these fuels only when absolutely necessary. This will result in better environment, smaller risk of global warming and their availability for a longer period of time.

Alternative sources of energy-
1.Solar energy.
2.Hydropower
3.Biomass.
4.Nuclear power.
5.Wind power.
