State any five steps to reduce the consumption of coal and petroleum products.
The consumption of coal and petroleum products can be reduced in the following ways:
-Use stairs to climb at least up to three floors of a building instead of taking a lift. This will save electricity.
-Bicycles should be used for covering short distances to save precious fuel like petrol (which is used in cars, scooters and motorcycles)
-Use energy efficient electrical appliances to save electricity. This can be done by using Compact Fluorescent Lamps (CFL) and fluorescent tube-lights instead of traditional filament-type electric bulbs (because CFL and tube-lights consume much less electric energy as compared to filament-type electric bulbs for producing the same amount of light).
.-Public transport system (local bus and train service) in the cities should be improved so that people do not commute in their personal vehicles. This will save a lot of petrol and diesel
-Switch off lights, fans and other electrical appliances when not needed.
