this ppt was presented on fossil fuel by Mr.Amanullah Adeel and scholar student originally from Afghanistan at Shivaji University, Kolhapur Maharashtra India. This is focused on energy production and consumption in worldwide and fossil fuels impacts on environment.

3. Fossil Fuels
• A fossil fuel is a nonrenewable
energy resource formed from
the remains of organisms that
lived long ago (300 millions
years ago); examples include
oil, coal, and natural gas.
• Most of the energy we use
comes from this group of
natural resources called fossil
fuels.
• Everything you do, from the
food you eat to the clothes you
wear requires energy.

4. How Fossil-Fuel Deposits Form

5. Types of fossil fuels

6. Oil and Natural Gas Formation
• Oil and natural gas result from the decay of tiny
marine organisms that accumulated on the
bottom of the ocean millions of years ago.
• These remains were buried by sediments and
then heated until they became complex energy-
rich carbon molecules.
• These molecules, over time, migrated into the
porous rock formations that now contain them.

7. Petroleum
• Petroleum is a liquid mixture of complex
hydrocarbon compounds that is used widely
as a fuel source.
• Petroleum, also known as crude oil.
• Anything that is made from crude oil, such as
fuels, chemicals, and plastics, is called a
petroleum product.

8. Natural Gas
• About 20% of the world’s nonrenewable energy
comes from natural gas.
• Natural gas, or methane (CH4), produces fewer
pollutants than other fossil fuels when burned.
• Vehicles that run on natural gas require fewer
pollution controls.
• Electric power plants can also use this clean-burning
fuel.

19. Fossil Fuels
disadvantages
• Fossil fuels are central to life
in modern societies, but there
are two main problems with
fossil fuels.
1. The supply of fossil fuels is
limited.
2. Obtaining and using them has
environmental consequences.

23. Air Pollution
• The quality of coal varies. Higher-grade coals, such
as bituminous coal, produce more heat and less
pollution than lower-grade coal, such as lignite.
• Sulfur, found in all grades of coal, can be a major
source of pollution when coal is burned.
• The air pollution and acid precipitation that result
from burning high-sulfur coal without adequate
pollution controls are serious problems in countries
such as China.
• However, cleaner-burning coal technology has
dramatically reduced air pollution in countries such
as the United States.

25. The Environmental Effects of
Using Oil
• Petroleum fuel releases pollutants when
burned.
• These pollutants contribute to smog and
cause health problems.
• Many scientists think that the carbon dioxide
released from burning petroleum fuels
contributes to climate change.

28. Conclusion
 Fossil fuels are limited sources of energy.
 These sources are widely used in worldwide.
 The top users are developed countries such as USA.
 the highest amount of them are used to generate
electricity.
 Almost all environmental pollution and disasters
like air pollution and acid rains come from fossil
fuels (Co2, Nox, Sox…).
