The three ways to reduce the use of petrol are given below :
(i) Switching to alternative sources such as solar energy in the forms of solar heater, solar cookers, use of natural gas and wind energy are some ways to reduce their usage. We can also reduce the use of these natural resources by using public transport and carpool.
(ii) Preference of alternative resources should be given for using renewable natural resources such as the sun and the wind. Windmills use wind energy to produce electricity. The solar energy is used to heat water, cook food and to generate electricity.
(iii) Environmental education plays an important role in creating awareness. Through environmental education, people come to know about their rights and duties towards nature.
