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
