Some sources of energy are renewable like sun, wind, flowing water, ocean, wood, biomass etc. Some sources of energy are non renewable like coal, petroleum and natural gas. 3 3. Conventional sources of energy :- a) Fossil fuels :- are fuels formed inside the earth from the remains of plants and animals after millions of years.
Coal and petroleum. Coal and petroleum are derived from fossil fuels which are non-renewable. They will get depleted in due time. Hence, proper management for consumption of fossil fuels is important. Their combustion pollutes our environment due to the production of oxides of carbon, sulfur and nitrogen. Therefore, we need to use these

Coal gas is obtained during the processing of coal to get coke. It is used Coal gas was used for street lighting for the first time in London in 1810 and in New York around 1820. Now a days, it is used as a source of heat rather than light. These days, bitumen, a petroleum product, is used in place of coal-tar for metalling the roads. Fig. 5.3

Coal and petroleum. 1. COAL AND PETROLEUM BY:PALLAVI TIWARI. 2. • Coal and petroleum are sources of energy that are non-renewable. They are made in nature, a long time before and they will finish a long time use. 3. • Coal is a combustible, sedimentary, organic rock, formed from vegetation.
As we already know, coal and petroleum are exhaustible sources of energy. If they are not used judiciously, they will not last for more than a few decades. Since they are widely used as sources of energy throughout the world, it is of utmost importance to think about their conservation. Conservation is the process of using a resource in a more careful way so that it can be made to last for a
