Conventional energy sources include fossil fuels like coal, petroleum/oil, and natural gas as well as firewood. Coal is a black-brown rock that is abundant and produces much of the world's electricity but is also dirty and harmful. Petroleum is a liquid fuel found underground that is used for gasoline and plastics. Natural gas provides energy for heating, electricity, and vehicles. Firewood is a renewable resource that is traditionally used as fuel but causes air pollution.

4. WHAT ARE CONVENTIONAL
RESOURCES
Energy that has been used from
ancient times is known as
conventional energy. Coal,
natural gas, oil, and firewood are
examples of conventional energy
sources.

6. TYPES OF FOSSIL FUELS
1. Liquid Hydrocarbons- Petroleum (oil)
2. Coal
3. Natural Gas

7. Coal
• Coal exists in many forms therefore
a chemical formula cannot be written for it.
• Coal is a fossil fuel that is made by carbonized
vegetable material. It is a black-brown
sedimentary rock.
•Produces 62% of world’s electricity.
•Most abundant fossil fuel and could
easily last at least 200 years

8. Advantages and Disadvantages
Pros
• Most abundant fossil fuel
• Major U.S. reserves
• 300 yrs. at current
consumption rates
• High net energy yield
Cons
• Dirtiest fuel, highest carbon
dioxide
• Major environmental
degradation
• Major threat to health

9. • Petroleum is a fossil fuel and is an oil that is found
underground. Sometimes we call it oil. Oil can be
as thick and black as tar or as thin as water.
Petroleum has a lot of energy. We can turn it into
different fuels - like gasoline, kerosene, and
heating oil. Most plastics are made from
petroleum, too.
• Petroleum is buried underground in tiny pockets
in rocks. We drill wells into the rocks to pump out
the oil.

11. 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.

12. Natural Gas
• Natural gas provides 29% of our
energy and is used to heat about half
the homes in the United States.
• It is a raw material in a variety of
common products, such as paints,
fertilizers, plastics, medicines, and
antifreeze.
• Natural gas is also used to generate
33% of our electricity.

13. FIREWOOD
Fire Wood is a fuel, such as firewood, charcoal, chips,
sheets, pellets, and sawdust.
Firewood is wood that has been cut into pieces so that it
can be burned on a fire.
firewood used as fuel for a fire.

14. Firewood is any wooden material that is
gathered and used for fuel.
Generally, firewood is not highly processed
and is in some sort of recognizable log or
branch form.
Firewood is a renewable resource.

15. Advantages
Wood is a domestic, traditional and renewable resource
that is locally available.
It CO2-neutral: carbon that is released during burning is
part of the natural carbon circulation.
The use of wood for energy purposes can have positive
effects on forest management.
It is usable multiple times because poor quality wood, small
wood and scrap wood is primarily used for energy purposes.
