• Fossil Fuels
- Coal
- Oil and Natural Gas
• Enrichable Uranium

3. Coal
• Coal is mined
• Sedimentary Rock
• Formed from
- Underground
- Dead organic mater
• Coal is burned in
factories to heat water
that turns electric
turbines.
4. Oil
• Oil is found through
drilling
• It is used for many
things:
• Burned like coal in
power plants
• Refined to produce
gasoline which is
used in motor
vehicles
5. Natural Gas
• Collected from natural
gas wells
• Burned to turn
turbines
- Heat water and
produce steam
- Natural Gas/ Steam
Combination
Generator
• Used in Fuel Cells
6. Nuclear
• The uranium used is mined or
milled before being processed
• After processing, pellets are
placed into rods which are
placed into bundles.
• Uranium bundles are used in
Fission reactions
- Fission; Splitting of uranium-
235 atom by catching a free
neutron
• Fusion
- Two atoms collide to form
one atom
7. Incineration
• Trash and waste are
burned
• Heat produced is
used to heat water
• The water changes to
steam and turns
turbines to generate
electricity
8. Inexhaustible Energy
• Wind
• Solar
• Hydroelectric
• Geothermic
• Wave Energy

9. Wind
• Windmills have
blades that are
pushed by wind
• These blades are
connected to a
turbine. When the
blades spin, the
turbine generates
electricity.
10. Solar
• Converted in two
different ways:
- Sunlight is
redirected to a
building to heat
water…etc
- Sunlight is
absorbed directly
through solar cells

11. Geothermic
• Heat from inside of
Earth
- Tapped
• May be used to heat
or cool homes
• Heat used to
produce steam and
turn turbineshttp://www.geothermalpowerplant

12. Wave Energy
• Waves are harnessed
to produce electricity
• Direct Method
- Waves move a
special turbine up and
down
• New Method
- Described in picture
