write any two demerits of conventional source of energy
Answers
1.Accessible: The deposit of minerals is widely accessible and completely identified. Thus the identification, extraction and usage can be widely done.
2. Wider scope: People are much accustomed to the exploitation and usage of conventional sources, especially firewood. This is the basis of living, especially in rural areas.
3. Basis of many industries: fossil fuels are the basis of the functioning of many petrochemicals and other related industries.
4.Energy generation: The generation of electricity still uses coal as the major power source. It can be easily converted to electricity.
But the consequent exploitation of these conventional sources has many disadvantages. Some of them are:
5.Pollution: The major disadvantage of these conventional sources is that they cause high pollution. The burning of firewood and fossil fuels result in air pollution. This can be avoided by using these non-conventional sources.
6.Exhaustible: The major problem while using conventional sources especially fossil fuels is that they are exhaustible sources. It takes millions of years for them to be renewed and replenished. But non-conventional sources are renewable sources that do not get exhausted.
7. Risky: Non-conventional energy extraction is safer. Many accidents occur while extracting energy from mines.
8. High cost: The extraction of these energy sources are very costly both economically and environmentally. The cost of energy production and extraction is much lesser for non-conventional sources if the initial cost of establishment is borne.
