advantages of conventional resources of energy?
fossils fuels are energy rich resources that combust easily and release a good amount of energy when burned. thus they support heavy energy requirements.
coal, petroleum and natural gas and running water are reliable energy resources and the power generated from them is consistent and they can be stored and used on demand that goes a long way in preventing wastage.
while cost of raw material is high for fossil fuels, high calorific value results in in a relatively low cost per unit of energy . hydropower is also one of the less expensive sources of electricity.
fossil fuels resources can be transported easily to areas of power generation by road, railways or waterways. the power generated can be transmitted easily and are therefore linked up to power grids.
ONLY FOR HYDROPOWER - though a conventional source, can be renewed as it uses a natural resource water. hence it can sustain energy requirements for generations to come. its also a clean energy resource as it does not involve combustion and there is no emission of GHGs. natural gas is also a cleaner fossil fuel compared to coal and petroleum .
disadvantages of conventional resources of energy?
other than hydropower, they’re not eco friendly resources as they involve huge carbon emissions that pollute the environment leading to global warming which is one of the major causes of climate change
mining, extraction and combustion of fossil fuels lead to a release of SULPHIDES, ARSENIC, DUST AND OTHER POISONOUS GASES into the atm. this causes grave health risks and scars the landscape. (Not hydropower)
theyre non renewable and this supply challenge is biggest disadv. over utilization of these resources over a period of time will deplete the current reserves and they are not sustainable.
though hydropower is ecofriendly, but the dams that are constructed to harness it can bring about ECOLOGICAL IMBALANCE, INTENSE FLOODING AND DAMAGE TO THE ENVIRONMENET.
there not cheap, moreover transportation costs of the fossil fuels can be an expensive proposition also.
occurrence of coal?
lies as a sedimentary rock below the surface of the earth
occur in hot, wet, swampy regions like deltas, coastal plains and river valleys
coal is formed by the decay and decomposition of vegetative matter
over millions of years, these vegatative remains pile up and due to heat and immense pressure, they get modified into dark coloured, solid, combustible, organic, carbonaceous, stratified seams of sedimentary rock known as coal.
uses and advantages of coal?
traditionally used for cooking fuel and heating in the domestic sector
as a major source of heat energy, it also has major role in industries as a source of power, it can be converted into gas, oil, and thermal electricity.
forms a basic raw material for production of cement, chemicals, dyes, fertilizers, paints, synthetics, explosives and many more.
used in steel industries for smelting iron ore in the blast furnace.
by products are BENZOL, AMMONIA GAS, NAPTHA, PHENOL TAR AND SULPHUR which have multifarious uses.
disadvantages of coal?
burning coal is major source of pollution and GHG emissions. in addition to CO and heavy metals like Mercury, the use of coal releases SO2, a harmful substance linked to acid rain.
coal take many millions of years to form which means we may be using this finite resource faster than it can replenish itself, thus it is not a sustainable source of energy.
coal mining tends to make the land barren due to deforestation and destroys the habitats of the wild animals.
types of coal and their uses?
Anthracite - above 90 % carbon content , best quality, most preferred, moisture free, lesser smoke generation , lesser ash, lesser pollution, it burns for a longer time and leaves very little ash behind, it is preferred for domestic purposes, metallurgical purposes and in iron and steel industry, has high heating value
Bituminous - 70-80% carbon content, most used, easily available and is widely used for domestic purposes in India, used to produce coke, coal gas and steam coal, mainly found in Gondwana coalfields.
Lignite - 60-70% carbon content
Peat - very poor carbon content (less than 50%)

how is hydel power generated?
a hydroelectric power plant consists of a high dam that is built across a large river to create an artificial reservoir, along with a power generation station, where the process of energy conversion to electricity takes place.
mention the advantages of hydel power.
an eco friendly source of power. its non polluting as no toxic emission take place during power generation.
water is a renewable source of energy and the same water can be used multiple times for the same purpose of power generation .
though initial cost of installation are high, its cheaper on the long run.
mention the disadvantages of hydel power.
cost of building dams is very high, thus its not very economical.
building of dams disturbs the equilibrium and may lead to earthquakes. it causes flooding and leads to displacement of large sections of population.
hydel power projects cause a huge loss of biodiversity as large areas are cleared of vegetation to make space for construction of reservoirs and power stations. When a large dam is built, the result is a downstream loss of a great many dish species that are important to riverine populations. thus , environment costs of hydel projects are quite high.
