Energize!
The types of energy in our world

2. Renewable Resource:
A resource we get from the earth, that we can run out of, but we can always get more of.
Vegetables
Fruits
Trees
Plants
Animals

3. Nonrenewable Resource:
A resource we get from the earth, that we can run out of someday. Once these resources are gone, we can NEVER get them back again in our lifetime.
Precious gems and minerals
Extinct animals/plants
Fossil fuels
Petroleum oil
Natural gas
Coal
Propane

4. Fossil Fuels takes millions of years to form (make)
animals and plants die and are buried under layers of sedimentary rock
Types of fossil fuels:
coal
natural gas
oil
Gasoline is NOT a fossil fuel but fossil fuels are used to make gasoline/petroleum

6. Examples nonrenewable resources

8. More examples of other types of thermal (heat) energy that do not use fossil fuels

9. Inexhaustible Resource:
A resource we get from the earth, that we will never run out of.
Sun
Water
Wind
Dirt

10. Solar Energy comes from the sun natural resource
does NOT cause pollution
cheap…sun’s rays are free
solar panels can be expensive
inexhaustible resource (never used up)

11. Examples of Solar energy

12. Wind energy comes from the wind natural resource
does not cause pollution
cheap, wind is free
unreliable because sometimes the wind does not blow
wind farms becoming more popular
inexhaustible resource (never used up)

13. Examples of wind energy

14. Hydro Energy comes from moving water natural resource
does not cause pollution
cheap, water is free
unreliable because sometimes water is not available
inexhaustible resource (never used up)

15. Examples of hydro energy
long ago

16. Static Energy comes from friction manmade and natural
does not cause pollution
cheap, rubbing 2 surfaces together
not powerful enough for human to always use
inexhaustible resource (never used up)

17. Examples of Static Energy
sometimes called “static electricity”

18. Chemical Energy comes from batteries or combustion
manmade from natural resources
expensive to create
causes pollution sometimes
If using fossil fuels to make
researching new ways to make (wind, water)
both inexhaustible and nonrenewable depending on how its made

19. Examples of Chemical Energy

20. Batteries

21. Chemical Energy comes from food that an animal eats
from natural resources

22. Chemical Energy

23. Geothermal Energy Comes from inside the Earth
Heat, steam, and magma found INSIDE the Earth
Natural resource
Does not cause pollution
Free from Earth, materials to get it out are expensive
Inexhaustible, but not found everywhere

25. Geysers (steam)

27. Biofuels Comes from plants and algae Can come from animals feces
Natural resource
Does not cause pollution
Cheap, but mainly used by farmers
Renewable, but can only be used in certain types of engines

30. (heat energy) Thermal Energy comes from the earth – fossil fuels
natural resource
decaying/decomposing plants and animals that died MILLIONS of years ago
causes pollution
expensive to get out of the earth
we will run out someday
nonrenewable resource (cannot be made)

31. Examples of Thermal heat using nonrenewable resources

32. All make electric energy
