Coal is a complex mixture of organic chemical substances containing carbon, hydrogen and oxygen in chemical combination, together with smaller amounts of nitrogen and Sulphur.
Oil shale resource is called unconventional oil resources to distinguish them from oil which can be extracted using traditional oil well methods (e.g., conventional oil resources). Most of the world's oil reserves are recorded as unconventional crude oil. Oil shale deposits represent staggering resource figures. Estimates by the U.S. Geological Survey suggest a global resource of 3 trillion (1012) barrels of oil, but reasonable estimates as high as 12 trillion barrels have been made. About half of the resource is located in the western United States. This articles aims to sight some light on the oil shale as the important types of unconventional oil deposits in the earth as well as how much can be economically recovered from oil shale.
All of us want an affordable and reliable energy source which we can only get by using coal energy. Although using coal energy is very significant for us and living without it would become impossible, we should always open our minds to the damage the continuous use of coal energy will eventually bring to us and to our environment.
Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulphur, oxygen, nitrogen. Ultimate analysis is also known as elemental analysis, it is the method to determine the Carbon,Hydrogen,Nitrogen,Sulphur and Oxygen content present in solid fuel.

ORIGIN AND Nature OF COAL Coal is a fossil fuel composed essentially o.pdflonkarhrishikesh
ORIGIN AND Nature OF COAL Coal is a fossil fuel composed essentially of compressed
altered plant remains. Under circumstances which have been replicated in many places on the
planet over the past 350 to 400 million years, plant tissue has been buried under anoxic (oxygen-
free) conditions, allowing plant tissue to be incompletely decomposed by anaerobic bacteria.
Economically viable coal deposits form when remains of entire forests are buried and preserved
by later sediments. Over millennia,such buried plant tissue may be converted through a series of
stages involving microbial activity, pressure,and heat into peat, lignite, sub-bituminous, and
bituminous coal,or the rarest coal, anthracite, the form of coal with the highest amount of energy
per kilogram. Coal is composed predominantly of the element carbon ( C ) along with hydrogen (
H ) and nitrogen ( N ) . Carbon content of coal ranges from 45 percent up to as much as 98
percent in rare anthracite. Most coal used to produce electricity contains between 50 and 70
percent carbon. Buming coal,therefore, produces large amounts of , themain agent of global
climate change. Question 4: Burning 1 kilogram of C produces about 3.7 kilograms of CO 2 .
Assume typical coal contains 60 percent C . How much CO 2 is released per tonne of coal
burned? Question 5: Recall that the United States produces about 1,100 million tons of coal each
year-equal to 1,000 million tonnes. How much CO 2 would be released each year? Question 6:
Slightly more than 4,000 million tonnes of coal were burned globally in 2003. How much CO 2
was produced, assuming 60 percent C content? Question 7: According to the World Coal
Institute, the world is expected to consume 7,000 million tonnes of coal each year by 2030, with
China accounting for half the projected increase. How much CO 2 would be produced by coal
burning in 2030 ? Question 8: How can global CO 2 emissions be controlled, in your view, if
these forecasts prove accurate? Discuss the implications if they are not controlled. DAL BED
METHANE When plant matter is converted into coal,methane is also formed,the main ingredient
in natural gas. The methane may be trapped in the sedimentary rock containing the coal. Some of
this trapped gas is released when coal is mined, which can lead to dangerous explosions. These
explosions are the reason for most miners' deaths in underground mines. Large mines may
release up to 1 million cubic feet per day of methane. This can be a significant souree of
atmospheric methanc, a powerful greenhouse gas. It is also a potentially valuable energy
resource. OXIDAtion of Pyrite and Water PolLUTION One of the most widespread and
polluting reactions is that of the oxidation of the minetn): pyrite, illes galled "fool's gold." Pyrite
is found in virtually all coals as well as in the When the coal is stripped away,the pyrite-bearing
sediment is exposed to oxidation fossil soils immediately below the coal seams: and
hydration,producing sulfaric acid. The.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

- COAL IS AN UNRENEWABLE SOURCE OF
FUEL
WHY?
- COAL IS FORMED FROM VEGETATION
THAT CAN BE AS OLD AS 400 MILLION
YEARS OLD. (THAT IS WHY IT’S CALLED A
FOSSIL FUEL)
6.
The earliest use of coal in the Americas was the
Aztecs
In the 1300s in what is now the United States,
Native Americans used coal for cooking,
making clay pots, and heating.
Large-scale coal mining developed in the
Industrial Revolution when demands for
energy skyrocketed
The first documented mining of coal in the US
was 50 tons dug in 1748 in Virginia
7.
In the past, coal had a variety of uses.
Gas for gas lights
domestic heating, railroad fuel and for stationery
steam engines.
Heating for the iron and steel industries
Weapons for the civil war
8. Over time
different ways of
creating energy
have been
discovered.
These ways are a
lot more complex
it effects the
environment a
lot. Some of the
ways that have
been developed
over time are
Biomass, Wind,
Geothermal, and
Hydropower.
These ways are
not only a lot
better for the
environment but
more efficient.
Coal covers about 21% of energy consumption. Even
though it isn't the smart choice it will still keep our cities
running until the next 25+ years.
12. Energy lost from coal
65% lost in
power plants
10% lost on
transmission lines
(stray voltage)
13. Formation of coal
Organic matter derived mostly from land
plants accumulates in low-energy
environment (like a swamp).
Oxidative decay uses up lots of oxygen,
rendering the sediment pore waters devoid
of oxygen (anoxic).
Gentle cooking and pressing (lithification)
as a result of increasing burial depth
remove the pore water and increase carbon
content (due to release of volatile
components of the organic molecules).
Low grade coal (lignite) cooked very little.
High grade coal (anthracite) cooked a lot
(close to being a metamorphic rock).
Lower grade coal tends to contain minerals
such as pyrite, which formed under the
reducing (low-oxygen) conditions.

18. Worldwide, compared to all other fossil fuels, coal is the most abundant and
widely distributed across the continents
998 billion tons
The resulting ratio of coal reserves to production is approximately 164
years (at current rates of production and no change in reserves)
Significant reserves are found in the United
States and Russia but not in the Middle East.

20. Availability
of Coal Mines
Two types of coal
mining
Surface mining
There are over
1000
surface
mines in the U.S.
Underground
mining
There are over
1000 underground
mines in the U.S
.Requires
more
workers, but is
the
most
efficient process
22. There are many
precautions coal miners
have. They where a
special device that
detects poisonous gases
that can harm humans.
They used canaries to
detect gases if the canary
died that meant you got
to get out of that mine.
23. Coal production has increased by more than 70% since
1970
9 out of every 10 tons of coal mined in the United States
today is used to generate electricity
56% of electricity in US is coal-generated
Use of coal is not limited to electricity generation:
Make chemicals, cement, paper, metal products
Methanol, ethylene
About 9 percent of U.S.-mined coal is exported to some 40
countries
24. The United States has a 300-year
supply of coal, if it continues to
use it at the same rate as today
Worldwide coal consumption is
supposed to increase 2% per year
from 2005 to 2030
29 percent of total world energy
consumption in 2030
25. There will likely be a significant increase in
the use of coal for electricity generation in
countries such as China and India
New technologies will continue to enhance
our ability to identify the shape and
composition of untapped coal reserves
26. WHAT ARE THE ADVANTAGES OF COAL?
- HIGHER HEATING VALUE COMPARED TO BIOMASS.
- MORE ABUNDANT THAN OIL.

27. The combustion of coal produces carbon dioxide(CO2) and nitrogen
oxides with varying amounts of sulfur dioxide (SO2) and other
pollutants
Coal-fired power plants represent the largest source of carbon dioxide
emissions, which is a major cause of global warming
Coal-fired power plants represent the largest source of carbon dioxide
emissions, which is a major cause of global warming
Sulfur dioxide reacts with oxygen to form sulfur trioxide (SO3) gas,
which in turn reacts with moisture in the air to form sulfuric acid. This
acid in the atmosphere is returned to the Earth in the form of acid rain.
