Essential Question: What do the different energy resources have in
common? What is different?
• When we use electricity in our home,
the electrical power was probably
generated by burning coal, by a nuclear
reaction, or by a hydroelectric plant at a
dam. Therefore, coal, nuclear and hydro
are called energy sources.
Topic: Energy Resources
Essential Question: What do the different energy resources have in
common? What is different?
• Energy sources are divided into
two groups.
– Renewable (an energy source that
can be easily replenished)
– Nonrenewable (an energy source
that we are using up and cannot
recreate).

Essential Question: What do the different energy resources have in
common? What is different?
• Advantage- A good reason to do or
use something.
– Example: The advantage of using a
calculator is math is quicker.
• Disadvantage- The reasons why
doing something would be bad.
– Example: The disadvantage of using
a calculator is you could punch in
the number wrong and not know it.

Examples of Renewable Energy
• Solar Energy- Solar • Advantagesenergy is the sun’s

that reach the Earth.
– Low impact on the
environment.
• Disadvantages– Sunlight is not the same
all the time.
– You need a LOT of solar
panels.

Examples of Renewable Energy
• Hydropower- Produces
the most amount of
electricity in the U.S.
Energy from moving
water.
• Advantages– Generators do not
pollute the air.
– Also helps stop floods
from rivers.
• Disadvantages– Stops the migration
of fish
– Could change water
temperature
– Could impact plants
and animals next to
plant.

Examples of Renewable Energy
• Geothermal- Energy
from the heat inside
the Earth. Heat is
always coming out of
the Earth.
• Advantages– Does not pollute
the air
– Earth is always
hot so never
going to run out
• Disadvantages– Have to find a
place to drill
(time consuming)
– Wells could stop
producing steam

Examples of Renewable Energy
• Biomass- The burning of • Advantagesorganic material made
– Alcohols are basically
from plants and animals .
Burning releases heat
clean burning
which is energy.
– Can be found
anywhere
• Disadvantages– Depending on what is
burned, could lead to
global warming
– A lot less energy is
released than other
types of energies.

Examples of Nonrenewable Resources
•
Fossil Fuels– Include Coal, Oil and
Natural Gas.
– Formed from the remains
of plants and animals over
millions of year.
• Advantages– Creates HUGE amounts of
energy.
– Power stations can be
made pretty much
anywhere.
• Disadvantages– Creates a HUGE amount of
pollutants
– Contributes to Green
House Gases
– Destroys land from mining.

• Disadvantages– Creates radioactive waste
which could cause cancer.
– Can be very dangerous
