Power or energy plays vital role in our lives.
we need it for -> industry, agriculture, transport etc.
there are 2 types of power resources IE. conventional and non-conventional resources.
Slide 2
FOSSIL FUELS
Fossils are remains of plants and animals that were buried under the
earth for millions of years. Coal, petroleum and natural gas are fossil
fuels as they are formed from fossils.
Slide 3
CONVENTIONAL SOURCES
the sources that have been in common use for a long time are called conventional sources of
energy..
EG. are firewood, coal, petroleum
and natural gas.
Slide 4
FIREWOOD
Firewood is primarily used for cooking and heating.
it is not a
very convenient and eco-friendly source of energy.
Collecting firewood
and cooking with it is time consuming and also burning firewood releases
carbon monoxide in the air. This results in air pollution and higher
levels of greenhouse gases.
Firewood is also the main cause of
deforestation.
COAL
it is bulky
to transport, it is also a source of pollution.
it is used in iron, steel, steam engines and to generate electricity
called as thermal power.
it is also called as buried sunshine.
The major coal producing
countries in the world are China, the USA, Germany, Russia, South
Africa, and France. In India, the major coal producing areas are
Raniganj, Jharia, Dhanbad and Bokaro in Jharkhand.
eg. of conventional sources
Slide 5
PETROLEUM
it means rock oil and is found between layers of rocks in the
form of a thick black liquid.
In its raw form petroleum is called crude oil which is drilled from oil
fields located in off-shore and coastal areas.
A major advantage of petroleum is that it can be easily transported in tankers
The major petroleum
producing countries in the world are Iran, Iraq, Saudi Arabia and Qatar.
NATURAL GASit is traditionally used as a
source of energy. It is found with petroleum deposits and is released
when the crude oil is brought to the surface.
HYDEL POWER
Electricity is generated from the energy of flowing water & The
energy derived from flowing water is called hydro power.
The electricity
generated from hydro power is called hydroelectricity.
Norway was the
first country in the world to develop hydroelectricity.
The leading
producers of hydro power in the world are Paraguay, Norway, Brazil, and
China.
