Essential Question
How do humans
being acquire and
utilize sources of
energy?
1. What are traditional fuel?
tree
Wood
Peat
Coal
Moss
Buried
under
sedimentary
rocks with
intense
pressure by
weight.
Formed
300 mya
2.How is coal formed?

Wood
Wood is the primary
source of energy in
rural areas. This
source of energy is
from trees thus it is
renewable. They burn
this source of energy
to cook and produce
heat.
3. How is Peat formed?
Peat forms when
plants in marshy
areas is not totally
carbonized.
Peat has the
potential to
become coal.
Sphagnum Moss
Most peat is
from Sphagnum
moss.
Peat Cutter
Burning Peat
4. What is Coal?
non renewable source of energy
Coal forms from the
accumulation and
preservation of plant
materials, usually in
a swamp
environment.
This what they mined in the movie
“October Sky”.

5. What are the two types of
nuclear energy?
Alternative Non-Renewable Energy
1.Fusion
2.Fission
6. What is Nuclear Fusion?
Nuclear fusion in
the CORE of the Sun
provide us Solar
Energy!
Nuclear fusion is an
atomic reaction that fuels
stars. In fusion, Hydrogen
nuclei combine together
to make Helium and
produce Energy.
Solar Energy is
Renewable energy.
Sunlight is used
as energy for
photosynthesis
Oxygen
CO2
Food
Water
7. What is Nuclear Fission?
Fission is the splitting
of a large atom like
Uranium into two or
more smaller ones and
produce ENERGY.
Fission reaction does not
normally occur in nature.
It is Non-Renewable

8. Give examples of fossil fuels.
1. Natural gas (cleanest)
2. Oil or Petroleum
3. Coal
Fossil fuels are Non renewable
9. What is Natural Gas?
Natural gas is the cleanest
burning fossil fuel,
producing primarily carbon
dioxide, water vapor and
small amounts of nitrogen
oxides. Natural gas is used
extensively in residential for
cooking and heating.
Natural Gas
The United States Department of Transportation (DOT) and
California Public Utilities Commission (CPUC) rules and
regulations regarding the odorizing of natural gas.
For your protection, Gas
companies add an
odorant called
MERCAPTAN to give
natural gas a distinctive
odor so leaks can be
more readily detected.
10. What is Oil or Petroleum?
Oil is a non renewable
source of energy made
from the remains of
ancient plants and
animals, compressed
deep in the earth. It is
usually found in layers
of sedimentary rocks.
11. What are the advantages and
disadvantages of using alternative
renewable energy?
Nuclear power is
alternative source of
energy but it is nonrenewable.
Alternative Energy creates less
Pollution compared to fossil fuel.
Alternative Energy
Dependent on nature.
Not always available.
Fossil Fuel
But fossil fuels are MORE convenient to use.
12. Of the following, which
energy source produces the
least amount of solid waste?
A. coal
B. natural gas
C. oil
D. peat
13. Why do green plants require
solar energy?
A. to produce their own food
B. to absorb nitrogen into their
roots
C. to release carbon dioxide into the
atmosphere
D. to decompose the dead or
decaying remains of animals
14. Which describes the difference between
nuclear fission and nuclear fusion?
A. Nuclear fission is the process that produces the
radiant energy of stars, and nuclear fusion splits a
heavier nucleus into smaller nuclei.
B. Nuclear fission splits a heavier nucleus into smaller
nuclei, and nuclear fusion is the process that produces
the radiant energy of stars.
C. Nuclear fission produces the energy in the core of
Earth, and nuclear fusion produces energy in nuclear
power plants.
D. Nuclear fission produces energy in nuclear power
plants, and nuclear fusion produces the energy in the
core of Earth.
15. A company has several factories around the
world and has decided to transition
from burning fossil fuels to using alternative
energy resources. How could a decrease in
burning fossil fuels impact the atmosphere?
A. It could decrease the oxygen levels of the
atmosphere.
B. It could increase the nitrogen levels of the
atmosphere.
C. It could decrease the carbon dioxide levels of
the atmosphere.
D. It could increase the sulfur dioxide levels of the
atmosphere.
16. Which is an advantage of safely using
uranium as an energy source rather than using
coal?
A. Uranium produces energy without polluting the
atmosphere, while burning coal can increase the CO2
in the atmosphere.
B. Uranium reduces the amount of thermal pollution,
while burning coal can increase the amount of thermal
pollution.
C. Uranium is the most cost-efficient energy resource,
while coal is the most expensive energy resource.
D. Uranium can be easily mined from deep within Earth,
while coal is a hard resource to mine from deep within
Earth.
For 17-24: Use the following sources of
energy as choices to complete the following
ideas.

water vapor and small amounts of
nitrogen oxides. Other fossil fuels
are coal and oil.
It is used extensively in residential
for cooking and heating.
Nuclear
fission
20. ____________________ is
the splitting of an atom's

original. This type of power
generation, is used in both
nuclear weapons and nuclear
power plants.
Wood
21. ___________ is the
primary source of energy in
rural areas. This source of
energy is from trees thus it is
renewable. They burn this
source of energy to cook and
produce heat.
Peat
22. ______________________ is
vegetable matter which has
been partially carbonized due to
the way in which it decomposes.
Over time, these have the
potential to evolve into coal.
