


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

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
1. Geologist find source near oil deposits
2. Wells are drilled and pump out gas
3. Cleaned in a processing plant
4. Odor (like rotten eggs) is added to gas
5. Gas is compressed
6. Finally, some is stored for later use
and the rest goes to people’s homes
through pipes



Pumped out of the ground using oil wells
Then transported in Pressurized pipelines to a natural gas
facility.
At the facility they remove unneeded materials and
liquids


Gas continues through pipelines


Compressor stations to maintain pressure
Can be stored underground in old wells


Propane, ethane, water, etc.
For later use
Distributed to customers through pipelines.

Measured in British
Thermal Unit (BTU)=
amount of heat that
can raise the temp of
1 lb of water 1°F.



Underground pipelines are safe, reliable and
protected from the weather
Cleaner burning than other fossil fuels, like coal
and oil. By using Natural Gas, the US has
reduced Carbon Emissions (pollution) into the
air by 7.7%= 84 Billion cars (since 2006)
Increased use can lessen several environmental
concerns
 Smog, acid rain, greenhouse gas emissions

Have about 100 years supply of
natural gas left at current levels
of pumping
(It takes a long time to create. So once
we use it all up it is gone!)

When burning any fossil fuel it
puts CO2 into the atmosphere.
(Increased levels of CO2 causes Global
Warming. )
 If
we continue to use Natural
gas at the rate we are using it,
we will run out!
 What
is Global
Warming?


Global warming computer game

Global Warming is
the gradual
increase of earth’s
temperature.
Greenhouse gasses
like CO2 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.

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

 Wind
power
captures the
energy in wind
to produce
electricity


Have been around since the 7th century
Used to grind and pump in a circular
motion.



Turbines produce
electricity.
16,000 turbines in


The state of California mandates
that by 2020, 30% of all electricity
must come from renewable
resources.
