A combustible (can catch on fire) material, found
deep in the Earth’s crust that has been under
pressure for millions of years.
There are 3 types of Fossil Fuels found in Earth’s
crust.
Natural gas
Coal
Oil
Coal is used for:
•Generating electricity
•Old coal furnaces
•Old locomotives
•Power generators at some factories
•Making steal
How can you conserve your use
of coal in your daily life?
Oil is used for:
•Transportation fuels
(gasoline)
•Fuel oil for heating
•Generating electricity
•Road oil (tar/ashphalt)
Man-made rubber
Plastics
cosmetics
WAX
medicine


Natural Gas
•Oldest fossil fuel
•Found deepest in
Earth’s crust
•Found as a gas
•Made from decayed
animals
Gas companies add a
sulfur smell to the fluid.
Why is this important?
 Heat
water – hot water
heaters
 Heat homes – furnaces
 Cooking – stoves
 Drying clothes – clothes
dryers

What are 4 ways we
use Natural Gas in
the household.




What are 3 ways
you can conserve
Natural Gas in your
home?
Heat water – hot water
heaters
Heat homes – furnaces
Cooking – stoves
Drying clothes – clothes
dryers

Have a limited supply
(It takes a long time to create. So once
we use it all up it is gone!)

When burning any fossil fuel it
puts greenhouse gases such as
CO2 and methane into the
atmosphere.
(Increased levels of greenhouse gasses
causes Global Warming. )
 What
is Global
Warming?
 (Climate Change)


Global Warming is
the gradual
increase of earth’s
temperature.
Greenhouse gasses
like CO2 and
methane enters the
atmosphere and
traps heat around
the earth.


Why is Global
Warming bad?

An increase in Earth’s
temperature can cause the polar
icecaps to melt.

Changes weather patterns:
Floods, hurricanes, tornados,
effects some biotic factors natural
timing.

1. Take shorter showers (less heat is used)

2. Install High Efficiency Fixtures in your home

3. Heat your home only when necessary (keep it at
about 68 °F)

4. Switch to electric appliances

5. Only wash with full loads (laundry and dishes)
 Energy
is the
ability to do work
or to produce
change.
We use energy to listen to music,
watch TV, play video games,
even our bodies use energy.



Our bodies need energy to do things
like move, digest food, regulate our
body temperature.
Plants need energy from the sun to
make their own food during
photosynthesis.
Volcanoes need energy to erupt.

Thermal Energy
 Electric
Energy = Electricity
Electricity is a type of
energy you use to
power appliances that
plug into the wall or
attached to a switch.
Electricity consumption
is measured in
Kilowatt-Hour (kWh).
Electricity can be
generated (made) by
renewable and
nonrenewable
resources.

Coal
Nuclear
Natural Gas
Remember
to turn out
the lights!!!
57% of your
electricity comes
from coal and
natural gas!

Geothermal Energy
Wind Energy
 Wind
power
captures the
energy in wind
to produce
electricity



Turbines produce
electricity.

GREEN
Energy
harnesses the
energy from
the sun to
produce
electricity
 uses
water to
generate
electricity
 Uses
heat
from the
earth’s core to
produce
electricity.

Is organic
material that is
burned to heat
water in boilers,
which produce
steam and spin a
turbine to create
electricity.


The state of California mandates
that by 2020, 30% of all electricity
must come from renewable
resources.
Problems with Our Dependence on Fossil Fuel
Is this Really Enough?
