1.Use less energy consuming lights and bulbs at home, offices and public places. 2.Judicious use of our limited energy resources. 3.Search for alternative and non-conventional sources of energy. 4.Use of bio-gas for cooking and lighting in houses.   5.Use of solar cookers, solar heaters and solar cells instead of conventional sources like fuel, LPG etc
