Question

Write an essay on conventional sources of energy

Answer 1

Essay on Conventional and Non-Conventional Energy Sources. Advertisements: Energy is produced mainly from non-renewable sourcessuch as petroleum, natural gas, coal and lignite. They are usually referred to as non-renewable, because extraction from the stock depletes the usable quantity remaining

Answer 2

Answer:

Energy resources are very much important in the context of economic development of the country. With the growing industrialisation, mechanisation of agriculture, and the development of transportation sector, the demand for energy resources is increasing day by day.

Thus a positive correlation exists between economic growth and demand for energy. Moreover, consumption of energy for domestic uses and public lighting has also been increasing.In India between 1952-53 to 1987-88 the GDP had increased annually at the rate of 3.7 per cent while the energy consumption had increased at the rate of 6.2 per cent per annum. Inspite of this, the per capita consumption of energy in India is low in comparison to that of developed countries. In India, more than half of the population does not possess the capacity to purchase commercial energy.

Again out of the total energy consumed, about half of it is obtained from non-commercial energy. In India the non­commercial sources of energy, mostly used by rural poor, are obtained from firewood, dung cakes and agricultural waste. But the commercial energy is obtained from oil and natural gas, coal, hydro-electricity and a little volume of nuclear energy.In India the consumption of commercial energy is too much dependent on oil and coal. About 47 per cent of the demand for commercial energy is met through petroleum oil. With the growing oil crisis, the importance of coal has also been realised in the country. Coal has an advantage over other fuels as it can be suitably converted into other types of energy like electricity, oil and gas.

In India, the coal is the principal source of electricity, at present with the significant development of thermal power projects based on coal. About 60 per cent of the total electricity generated in India is available from these coal based thermal power projects.
