Oil and natural gas are both fossil fuels formed from the remains of dead plants and animals over millions of years. They consist of hydrocarbons like methane and are used for heating, transportation fuel, and electricity generation. While oil and natural gas have similar uses as fuels, oil is generally cheaper and more widely used for powering vehicles and machinery. However, both resources are non-renewable and finite, so transitioning to renewable energy alternatives will be necessary as supplies are depleted over time. Careful planning is needed to manage dwindling oil reserves and prepare for potential supply issues.

2.  Oil and natural gas are naturally occurring chemicals that
are made up of just two elements -- carbon and hydrogen.
The class of chemicals based on carbon and hydrogen are
called hydrocarbons. The simplest hydrocarbon, methane, is
made up of one carbon atom and four hydrogen atoms.

3.  Over millions of years, layer after layer of sediment
and other plants and bacteria were formed. As they
became buried ever deeper, heat and pressure began
to rise. The amount of pressure and the degree of heat,
along with the type of biomass, determined if the
material became oil or natural gas.

4. OIL
 The general definition of oil includes classes of
chemical compounds that may be otherwise
unrelated in structure, properties, and
uses. They are used for food (e.g., olive oil),
fuel (e.g., heating oil), medical purposes
(e.g., mineral oil), lubrication (e.g. motor oil),
and the manufacture of many types of paints,
plastics, and other materials. Specially prepared
oils are used in some religious ceremonies and
rituals as purifying agents.

5. Organic
oils
Mineral
oils

6. The word ‘organic’ itself says that
it is related to “organs”.
Organic oils are produced in
remarkable diversity by plants,
animals, and other organisms
through
natural metabolic processes.
Several edible vegetable and
animal oils, and also fats, are used
for various purposes in cooking
and food preparation.
What is organic oil ?

7. What is mineral oil ?
The name "mineral oil" is
a misnomer(wrong) , in that minerals are
not the source of the oil—ancient plants
and animals are. Mineral oil is organic.
However, it is classified as "mineral oil"
instead of as "organic oil" because its
organic origin is remote (and was
unknown at the time of its discovery), and
because it is obtained in the vicinity of
rocks, underground traps, and
sands. Mineral oil also refers to several
specific distillates of crude oil. Crude oil
originates from ancient fossilized organic
materials, such as zooplankton and algae,
which geochemical processes convert into
oil.

8. NATURAL GAS
 What Is natural gas ?
 Natural gas is a fossil fuel used as a source of
energy for heating, cooking, and electricity
generation. It is also used as fuel for vehicles and
as a chemical feedstock in the manufacture
of plastics and other commercially
important organic chemicals. Fossil fuel based
natural gas is a non-renewable resource. Natural
gas is found in deep underground rock formations
or associated with other hydrocarbon reservoirs
in coal beds and as methane
clathrates. Petroleum is another resource and fossil
fuel found in close proximity to and with natural gas.

9.  In the 19th century, natural gas
was usually obtained as a by-
product of producing oil, since
the small, light gas carbon
chains came out of solution as
the extracted fluids underwent
pressure reduction from
the reservoir to the surface,
similar to uncapping a soft drink
bottle where the carbon
dioxide effervesces. Unwanted
natural gas was a disposal
problem in the active oil fields. If
there was not a market for
natural gas near the wellhead it
was prohibitively expensive to
pipe to the end user.

10.  oil and natural gas are fossil fuels that are used for heating.
They are both formed from the remains of dead plants and
animals. Both oils have similar uses but may differ in the effect
and outcome of their use.
 oil, or petroleum, is a flammable liquid that consists of
hydrocarbons and other organic compounds found beneath
the earth through oil drilling. Natural gas consists mostly of
methane and hydrocarbons or ethane.
 oil and natural gas are used for transportation that make
vehicles work; however, with the increase of technical
advancements in manufacturing vehicles, the demand for crude
oil becomes greater because most vehicles are designed to use
crude oil than natural gas. Another point why most vehicles and
machines are designed to use crude oil than natural gas is
because crude oil is cheaper than natural gas.

11. conclusion
 It takes oil to create ethanol (a corn based fuel), it takes oil
to make plastic, to make computers, to build economies
and nations - oil is needed.
 As we progress into the future, supplies will tighten and oil
prices will increase further.We've already felt the ripples
from the recent rises of commodity pricing. And as demand
from developing nations combines with an ever dwindling
supply - the global economy will soon begin to feel the
squeeze. So what does the future hold, no one knows.
Obviously we must find renewable energy solutions, but for
them to become our major energy supply is a long time
away and thus oil will remain an intricate part of our
society.

12.  We can wish it, we can dream it, but it will
never be, oil is not renewable, and
therefore in time it must be realized that
THEREWILL BE NO OIL.
 According to the IEA'sWorld Energy
Outlook for 2007: "An abrupt escalation of
oil prices after 2015 as a result of a global
supply crisis cannot be ruled out.“
 "The consequences of unfettered growth
in world energy demand are alarming.“
 We must remain aware of our options now,
make the best decisions looking forward,
and be prepared in all possible situations.
