Conventional energy sources are also called
As Non-Renewable sources of energy.
Once utilized, they cannot be replaced easily.
The examples of that energy sources are
Coal, Natural gas, Petroleum.
Uranium, Thorium and Lithium are consist in
This category.
It is composed of highly complex group of
Substance that are mainly the product of organic decay.
They have wide range of Physical and chemical
Properties.
It is formed by the modification of the plant matter
According to carbon content it is lignite at lower end and bituminous at higher end.
1- They are naturally occurring
fossils fuels with limited stocks.
2- These energy sources are
mainly in transportation sector.
3- It is mostly used to generate electricity for human as well as country development.
Sunlight is the main source of energy on the earth
as well as in the ecosystem.
All fossils fuels are organic in nature and thus sunlight is their source of energy.
The amount of solar energy striking on the earth
is tremendous. The solar energy received by the
Earth is equivalent to 684 billion tones of coal.
Solar energy is used to produce heating effect
As well as Electricity.
Solar energy
Solar energy is the mostreadily available source ofenergy. It does not belong toanybody and is, therefore,free. It is also the mostimportant of the non-conventional sources ofenergy because it is non-polluting and, therefore,helps in lessening thegreenhouse effect.
It is one of the better source of Non-conventional
sources of energy for generation of the electricity.
It has better efficiency over tidal and solar energy
sources.
The site of the windmills shall be at higher
elevations so that velocity of wind is high. The
area should be open in such a way that the wind
strikes with a high velocity to the wind mills.
In some states like Maharashtra, Gujarat,
Tamilnadu gaining a lot of popularity.
In our country, there is a lot of research is going
on the generation of electricity by the windmills.
wind mills are also used for to pumping the
water for agricultural purpose, for grinding
food grains.
Wind energy is the kinetic energyassociated with the movement ofatmospheric air. It has been used forhundreds of years for sailing,grinding grain, and for irrigation.Wind energy systems convert thiskinetic energy to more useful formsof power. Wind energy systems forirrigation and milling have been inuse since ancient times and sincethe beginning of the 20th century itis being used to generate electricpower. Windmills for water pumpinghave been installed in manycountries particularly in the ruralareas.
Tides generated by the combination of the moon and sun’s gravitational forces
Greatest affect in spring when moon and sun combine forces
Bays and inlets amplify the height of the tide
In order to be practical for energy production, the height difference needs to be at least 5 meters
Only 40 sites around the world of this magnitude
Overall potential of 3000 giga watts from movement of tides
First generation, barrage-style tidal power plants
Works by building Barrage to contain water after high tide, then water has to pass through a turbine to return to low tide
Sites in France (La Rance), Canada (Annapolis), and Russia
Future sites possibly on Severn River in England, San Francisco bay, Passamaquoddy
