Question

The use of fossil fuels is harmful to us. Explain this statement and also mention some of the alternate fuels being used by man.

Answer 1

The use of fossil fuels such as petroleum oil and coal causes environmental pollution from which many serious health problems arise. Thus, the use of fossil fuels is harmful to us.

In order to overcome this, alternate fuels can be used by man. These alternate fuels are generated by renewable resources like the Sun, wind, water and soil. They are inexhaustible, easily found and can be used again and again. They do not cause environmental pollution. Some of the renewable alternate fuels are solar energy, wind energy and water energy. Solar energy is used to produce electricity through solar panels. It is also used for cooking purposes. Wind energy is used to generate electricity with the help of wind mills. Kinetic energy of flowing water is also used to generate electricity.
